- * Dashboard error boundary (App Router convention).
+ * Dashboard ROOT error boundary (App Router convention) — the catch-all for
+ * anything not caught by a more specific segment boundary (`sources/error.tsx`,
+ * `syncs/error.tsx`, etc.).
+ *
+ * DELIBERATELY DIFFERENT from the leaf-segment boundaries: those all now
+ * retry unbounded, because their specific throw (`Error: The destination
+ * stream closed early`) is a known, provenance-checked transport race — the
+ * underlying read already succeeded, only the RSC stream teardown raced. This
+ * boundary sits above `page.tsx` (the dashboard overview), which already
+ * fault-isolates every one of its OWN data reads via `safeRead()` — an
+ * individual source failing degrades that section to empty inline, it never
+ * throws up to here. So an error that DOES reach this root boundary is either
+ * (a) the same stream-teardown race, now unprovable-by-route because this
+ * boundary is shared by the whole segment, or (b) a genuine unhandled fault
+ * in render/layout code — precisely the class of bug `safeRead()` was built
+ * NOT to swallow. There is no error-reporting integration in this codebase
+ * (no Sentry/equivalent) — `console.error` here is the only diagnostic
+ * signal an operator has. Retrying an unprovable root-level fault forever,
+ * silently, would delete that signal for a real crash.
+ *
+ * So this boundary retries quietly (same skeleton, no failure copy, capped
+ * backoff) for a BOUNDED number of attempts — enough to absorb the ordinary
+ * transient race — and only after that repeatedly fails does it fall back to
+ * the pre-existing "Something went wrong" / Try again / Sign in again panel.
+ * That is strictly no worse than the boundary's prior behavior (which showed
+ * that panel immediately, every time) and materially better for the common
+ * case: a lone stream hiccup anywhere in the dashboard no longer flashes
+ * failure copy at the owner.
  *
  * Self-contained on purpose: it must not import server-only modules. The
  * dashboard shell (`RecordroomShellWithPalette`) transitively pulls in
  * `lib/owner-token.ts`, which is `server-only`; importing it here would break
- * the client build.
- * Stripe/Linear-style empty state lives below; the user can retry or sign
- * back in. See https://nextjs.org/docs/app/getting-started/error-handling.

+ * Owner-raised 2026-08-19: "why is there no product-standard fused

+ * obvious one-line fix is wrong — is written up in
+ * `design-notes/fused-source-status-2026-08-22.md`. The short version:
+ *
+ * Freshness, activity, and the health verdict are THREE INDEPENDENT AXES that
+ * routinely disagree. A source can be syncing right now and still be broken; it
+ * can be fresh and have a failing run in flight; it can be stale precisely
+ * because the sync that would refresh it keeps failing. Today's code resolves
+ * that disagreement by LAST-WRITER-WINS: `deriveRenderedSourceStatus` returns
+ * early on `running` with `label: "Syncing"`, `tone: "muted"`, and
+ * `freshnessNote: null` (`source-actionability.ts`), so an in-flight run erases
+ * both the freshness note and whatever the verdict said was wrong. That is the
+ * fabricated-green defect in miniature: the most reassuring axis silently wins.
+ *
+ * This module fuses instead of overwriting, under one rule:
+ *
+ *   ACTIVITY IS ADDITIVE, NEVER SUBSTITUTIVE.
+ *
+ * "Syncing" is something a source is DOING, not something it IS. So the state
+ * slot always keeps the worst honest verdict, and syncing is appended as
+ * context. The fused line can never read cheerier than its worst axis.
+ *
+ * This module deliberately owns no label VALUES that `connection-evidence.ts`
+ * already owns — it composes the strings that module and

- * Records-segment error boundary (App Router convention) — partial-aware.
+ * Sources-segment error boundary (App Router convention) — SLVP bar: Stripe,
+ * Linear, Vercel, and Plaid never tell an owner "we hit a transient read
+ * interruption, retrying." The page renders, or it quietly shows last-known
+ * state. The owner never learns the backend hiccuped.
  *
- * The owner reported hitting "Couldn't load your connections" — every card
- * gone — during a reference rebuild, when a transient read failed mid
- * `router.refresh()` (a poll tick or a post-Sync revalidation;
- * `records-page-poller.tsx` / `connector-row.tsx`). A read blip at the very
- * moment the owner most wants the page (ChatGPT consuming deployment resources
- * mid-run) should never blank all 19 cards.
+ * Root cause of the throw this boundary catches (`Error: The destination
+ * stream closed early`, digest-stamped by Next): the read itself is fine. The
+ * `/_ref/connectors` read this page depends on returns 200 in ~1.2s — the read
+ * already succeeded. The throw is React's Flight/RSC streaming writer
+ * (`react-server-dom-webpack-server`) reacting to the destination (the HTTP
+ * response) closing before the stream finished flushing — e.g. a poll tick
+ * from `records-page-poller.tsx` firing `router.refresh()` while a prior
+ * refresh's stream is still in flight, or the tab backgrounding/throttling the
+ * connection mid-render. It is a client-transport race below the data layer,
+ * not a backend outage, so there is no "fix the read" available here — the
+ * fetch already succeeded by the time this fires.
  *
- * So this boundary is NOT a full-viewport takeover. It renders a compact,
- * top-anchored banner that:
- *   - frames the failure honestly as a *read* failure, not a data change;
- *   - names *when* the data was last confirmed live (last-successful-load
- *     timestamp, read from the client-side `sessionStorage` marker the poller
- *     stamps — see `last-known-read.ts`), without claiming cached rows exist;
- *   - offers an explicit Retry; and
- *   - quietly auto-retries once after a short delay, so a transient blip
- *     self-heals back to the live list without the owner lifting a finger.
+ * Given that, this boundary NEVER renders owner-facing failure copy, at any
+ * stage. It:
+ *   - retries immediately and then on a capped exponential backoff,
+ *     UNBOUNDED — there is no terminal "give up and show a Retry button"
+ *     state, because a manual-retry dead end is itself the thing the owner
+ *     complained about (parked on an error for an hour);
+ *   - while retrying, renders the exact same skeleton `loading.tsx` uses, so
+ *     a transient stream-teardown is visually indistinguishable from a normal
+ *     page load — never a warning-colored card, never the words "error",
+ *     "interruption", "retrying", "couldn't", or "failed";
+ *   - once a last-good render has happened at least once, adds ONLY a quiet,
+ *     dimmed "Updated Xs/Xm ago" caption under the skeleton — honest staleness
+ *     signal, framed exactly like a normal freshness note elsewhere in the
+ *     product, never framed as a failure.
  *
  * Self-contained on purpose (mirrors `dashboard/error.tsx`): a `"use client"`
  * boundary must not import server-only modules, since the dashboard shell
  * transitively pulls in `lib/owner-token.ts` (`server-only`). The last-known
- * snapshot therefore comes from a client-cached marker, never a server read
- * inside the boundary. See https://nextjs.org/docs/app/getting-started/error-handling.

- * Read-resilience acceptance invariants for the records segment [Defect 3].
+ * Read-resilience acceptance invariants for the sources segment [Defect 3,
+ * revised]. The prior version of this file pinned a banner that told the
+ * owner "Refreshing source status… The Sources view hit a transient read
+ * interruption. Retrying automatically before showing an error." — and, on a
+ * second failure, "Couldn't refresh your connections" behind a manual Retry
+ * button. The owner reported that failure-copy state sitting on screen for an
+ * hour and said, verbatim: "I should never see this" / "/sources should
+ * always work."
  *
- * The owner hit "Couldn't load your connections" — all 19 cards gone — during a
- * reference rebuild, when a transient read failed mid `router.refresh()`. These
- * pin the fix so it cannot regress to a full-viewport blank:
+ * THE STANDARD (stated explicitly by the owner): Stripe, Linear, Vercel, and
+ * Plaid never show a user "we hit a transient read interruption, retrying."
+ * The page renders, or it shows last-known state with a quiet staleness
+ * indicator. The user never learns the backend hiccuped. That is the MINIMUM
+ * bar, not the target.
  *
- *   1. The records error boundary first renders quiet retrying copy, not an
- *      explicit failure headline, and the eventual failure state is still a
- *      partial banner rather than a full-viewport takeover.
- *   2. The boundary reads a CLIENT-cached last-known marker (it must not import
- *      a server-only module) and surfaces last-known status + a retry.
- *   3. The boundary auto-retries once so a transient blip self-heals.
- *   4. The poller stamps the last-good read time and guards the soft
- *      revalidation so a throw never escapes the timer.
+ * Root cause the boundary now assumes: `Error: The destination stream closed
+ * early` is React's RSC streaming writer reacting to the HTTP response socket
+ * closing before the flight stream finished flushing (a poll-driven
+ * `router.refresh()` superseding an in-flight one, or the tab
+ * backgrounding/throttling the connection) — NOT a failed data read. The
+ * upstream `/_ref/connectors` call already returned 200. So this boundary
+ * treats every activation as recoverable-by-construction: it never renders
+ * error-shaped copy, retries unbounded on a capped backoff, and — while
+ * retrying — is visually identical to the ordinary `loading.tsx` skeleton,
+ * with at most a quiet "Updated Xs/Xm ago" caption once a last-known
+ * timestamp exists.
+ *
+ * These invariants pin the STRONGER property (no error copy ever reaches the
+ * owner, no terminal manual-retry dead end) rather than merely deleting the
+ * old, weaker pin:
+ *
+ *   1. The boundary source contains NONE of the retired failure-ish copy
+ *      ("error", "interruption", "retrying", "couldn't", "failed", "wrong")
+ *      in any owner-facing string.
+ *   2. The boundary renders the SAME `ListLoadingSkeleton` component
+ *      `loading.tsx` uses, not a bespoke banner/card — so the transient state
+ *      is indistinguishable from an ordinary page load.
+ *   3. The boundary retries on every mount (no `autoRetried`/"give up" flag)
+ *      with a capped, growing backoff, and never renders a manual "Retry"
+ *      button or link as a terminal state.
+ *   4. The boundary reads the CLIENT-cached last-known marker (it must not
+ *      import a server-only module) and, when present, renders only a quiet,
+ *      dimmed relative-time caption — never a claim that failed data changed.
+ *   5. The poller still stamps the last-good read time and guards the soft
+ *      revalidation so a throw never escapes the timer (unchanged contract).
  *
  * Source-regex over the shipped client components, mirroring the existing
  * records-list-view / sources-ia invariant style: these are `"use client"`
  * React components that the behavioral marker logic (last-known-read.test.ts)
- * already covers as a pure unit; here we pin the boundary's structural copy and
- * the load-bearing wiring from source.

+# Browser-stream: the captcha tap, and the false "logged in" claim
+
+2026-08-22
+
+Two owner-reported defects on the interactive browser-stream path, both
+repeated across several days. They are unrelated in mechanism but share a
+theme: the console asserted things it could not prove.
+
+## 1. "Can't tap the captcha on mobile" — the residual half
+
+Reported at least three times from 2026-08-18. Scroll and rotate worked; taps
+did not.
+
+### The iframe theory is wrong, and worth retiring explicitly
+
+A reCAPTCHA checkbox lives in a cross-origin iframe, so the natural suspicion is
+that synthetic pointer events do not cross the iframe boundary, or that
+coordinates fail to resolve inside the iframe's document.
+
+**That is not what happens here.** The remote input path is coordinate-based all
+the way down — neko dispatches X11 pointer events, and the CDP backend calls
+`Input.dispatchMouseEvent` with raw `x`/`y`. Both operate at the browser
+compositor level, *below* the DOM, so they cross cross-origin iframe boundaries
+by construction. Nothing in the path hit-tests the top document: there is no
+`elementFromPoint`, no `querySelector` against remote DOM, no frame targeting.
+The only `elementFromPoint` in the streaming server is a calibration-beacon
+diagnostic, not the input path.
+
+The captcha was never special. It is simply the one control an owner *cannot*
+work around, so it is where a general tap defect gets noticed and reported.
+
+### What two prior commits fixed, and what they left
+
+- `a21a9a1be` stopped *dropping* touch taps that reported a non-zero
+  `event.button`. Correct: `button` is mouse-state and must not gate touch.
+- `5274dbd4c` rerouted touch press/release onto the CDP mouse path, because
+  `Input.dispatchTouchEvent` does not reliably synthesize a `click`.
+
+Both are real fixes. Neither covers the residual case, because the first
+commit stopped *filtering* on `button` but still **forwards the raw value**, and
+downstream that value is not a filter — it is arithmetic:
+
+```js
+// remote-surface 1.5.2, controllers/neko-pointer-controller.js
+const x11Button = (event.button ?? 0) + 1;
+```
+
+X11 button 1 is primary. A touch `pointerdown` reporting `button === -1` — the
+same non-spec value `stream-viewer-pointer-input.ts`'s own doc comment documents
+as real on touch input paths — therefore becomes **X11 button 0**, which is not
+a button. neko presses nothing, and the tap never clicks.
+
+Verified by replaying the exact client payload through the real installed
+controller:
+
+| `button` on pointerdown | X11 call emitted |
+|---|---|
+| `0` (spec-compliant) | `buttonDown(1)` — correct |
+| `-1` | `buttonDown(0)` — **no button pressed** |
+
+`pointerup` was already safe by luck: the controller prefers the *remembered*
+press button over the event's own. `pointerdown` has nothing to fall back to.
+
+This also explains the reporting pattern. Engines that report a spec-compliant
+`0` always worked, which is why the bug never reproduced on desktop and why it
+looked intermittent rather than universal.
+
+### The fix
+
+`normalizedPointerButton` in
+`apps/console/src/app/(console)/syncs/[runId]/stream/stream-viewer-pointer-input.ts`
+pins touch and pen to primary contact at the payload boundary. Touch and pen
+have no secondary button, so this loses no information. Mouse is passed through
+untouched — its `button` is meaningful, and normalizing it would turn every
+right-click into a left-click.
+
+Guarded by `stream-viewer-touch-tap-oracle.test.ts`, which asserts against the
+**real dependency** rather than restating our own arithmetic, so a future
+dependency bump that changes the mapping fails loudly instead of silently.
+
+### Honest limits
+
+**This is not confirmed against a real phone.** I do not have the owner's
+device, and I did not attempt a Reddit login (OTP/bot-detection sensitive, and
+the owner has been explicit about not burning accounts). What is proven is
+mechanical: the payload the client sends, replayed through the real controller,
+pressed no button before this change and presses primary after it. Whether that
+was the *only* remaining cause of the owner's symptom is unverified — it is a
+genuine defect on the exact reported path, not a confirmed end-to-end repro.
+
+## 2. The false "logged in" state — the more dangerous half
+
+The UI told the owner he was already logged in to Reddit when he was not.
+
+### The evidence the UI used was a proxy
+
+`deriveSetupState` in `reference-implementation/runtime/static-secret-setup-status.ts`
+reaches `first_sync_running` / `first_sync_pending` for a browser session from
+`hasDraftSetupProgress`, which is satisfied by run evidence alone:
+
+```ts
+return hasSetupMaterial || (setupKind === "browser_session" && hasRunEvidence(input));
+```
+
+The console then rendered, in `connect/status/[connectionId]/page.tsx`:
+
+> "Login is complete and the first sync is running."
+
+**For a `browser_session` connection, the run IS the login attempt.** It starts
+precisely so the owner can sign in inside the streamed browser. So a run row
+proves a sign-in was *attempted*, never that it completed. The projection's own
+comment stated the flawed inference out loud — "(the owner completed login and a
+first sync started)" — which nothing in the projection verifies. `lastRun` also
+satisfies it, so a *previous* failed run made the UI claim login was complete on
+the current attempt.
+
+The asymmetry makes the defect obvious once seen. For the other two setup kinds
+the same states carry claims that **are** backed by evidence:
+
+| Setup kind | Claim | Backed by |
+|---|---|---|
+| `static_secret` | "The provider credential is captured" | `setup_material.present === true` |
+| `manual_upload` | "The import file is captured" | `setup_material.present === true` |
+| `browser_session` | ~~"Login is complete"~~ | **nothing** — `defaultSetupMaterial` pins `present: false` |
+
+### The fix
+
+The browser-session copy now describes only what is observed — a sync is
+running — and points the owner back at the browser, admitting the page cannot
+confirm the login itself. The static-secret and manual-upload claims are
+deliberately left intact, and a test pins them, so this does not over-correct
+into scrubbing information that is genuinely proven.
+
+Guarded by `browser-session-login-honesty.invariants.test.ts`, which fails on
+any phrasing that asserts a completed sign-in.
+
+### What was NOT fixed, and should be
+
+The connector layer already holds **real proof** of Reddit login state.
+`isSessionLive` in `packages/polyfill-connectors/src/auto-login/reddit.ts`
+fetches an owner-only JSON endpoint and requires HTTP 200 — ground truth, not a
+heuristic, and deliberately so per its own doc comment.
+
+**That verdict is never plumbed into the console.** Wiring it through would let
+the UI make a positive, evidence-backed claim instead of merely declining to
+make a false one. That is a larger change across the RI projection boundary and
+is left for a follow-up.
+
+Two related weaknesses found and not fixed here:
+
+- `isSessionLive` degrades to counting a logout-link selector when
+  `REDDIT_USERNAME` is unset — which is exactly the credential-less manual
+  handoff path. The repo's own tests document that this selector is unreliable
+  in both directions.
+- An instance flips to `status = 'active'` on first successful ingest and is
+  **never re-validated**. A session that worked in June and has since been
+  logged out server-side still projects `active` → `healthy`. There is no
+  `last_verified_at` on the credential row, and for browser sessions the
+  credential row is bypassed entirely.
+
+Both mean "connection active" is a durable-row claim, not a live one. That is a
+real instance of the same defect class and deserves its own change.
+
+## 3. "Couldn't reach the browser stream" — assessed, largely already sound
+
+Root-caused but not re-engineered, because the existing design is mostly honest.
+The give-up message fires after 10 attempts with backoff, and is followed by a
+diagnostic probe (`stream-reach-diagnostics.ts`) that recovers the real HTTP
+status and error code — necessary because `EventSource` collapses every
+pre-attach failure into a payload-less error. Four of six reasons already get
+specific, actionable copy.
+
+Two genuine residual gaps, left for a follow-up rather than fixed blind:
+
+1. `managed_surface_window_settle_unavailable` (a 503 the server describes as a
+   transient restart worth retrying) is not in the classifier's match list, so
+   it falls through to the vague generic copy.
+2. The generic message is shown *before* the probe resolves, so there is a
+   window where the owner reads network-flavored copy even when the cause is
+   precisely known moments later.
+
+Neither is a fabricated-green defect — the classification rests on a real HTTP
+status — so they are accuracy gaps, not dishonesty.

+# Connector coverage findings — USAA and Gmail (2026-08-22)
+
+Four owner-reported coverage gaps (ledger items D1–D4). Two of the four had a
+wrong premise in the report; the evidence is recorded here because each finding
+is the kind that gets rediscovered as something else entirely six months later.
+
+## D1 — USAA `transactions` stuck at 2 of 4: a marketing interstitial, NOT a UI change
+
+**The finding that will otherwise be rediscovered as "USAA changed their UI".**
+
+USAA serves a promotional interstitial in FRONT of a checking account page:
+
+```
+https://www.usaa.com/my/banking-offer/atm-deposit
+    ?accountId=…&accountType=checking&goto=https://www.usaa.com/inet/ent_home/CpHome
+title: "Find an ATM | USAA"      ("Depositing cash just got more convenient!")
+```
+
+`locateExportPage` navigated to the account URL, was redirected here, found no
+Export button, and reported `source_structure_changed` — whose owner-facing
+meaning is "the source's UI changed; retrying is pointless until the connector's
+selectors are revisited". **The selectors were fine.** The connector was looking
+at a page that never claimed to have an Export button.
+
+Only `LOGON_REDIRECT_RE` was checked after navigation. `/my/banking-offer`
+matched neither that nor `USAA_ACCOUNT_DETAIL_ROUTE_RE`, so it classified as
+`unknown` and fell through to the no-affordance path.
+
+### The correlation that proves it
+
+The denominator for `transactions` is **accounts, not statements**
+(`emitTransactionsDetailCoverage`, `state_stream: "accounts"`): 5 accounts, 4
+transaction-eligible (Chase is `external-account`).
+
+| account | type | offered ATM deposit? | outcome |
+|---|---|---|---|
+| Checking | checking | yes → interstitial | **gap** |
+| Family Checking | checking | yes → interstitial | **gap** |
+| Signature Visa | credit-card | no | covered |
+| American Express | credit-card | no | covered |
+
+**The 2 covered accounts were precisely the 2 credit cards** — the accounts that
+get no ATM-deposit offer. Both checking accounts hit the interstitial; both
+credit cards exported normally. That is the whole of the 2-of-4 gap. Captured
+live 2026-07-14 in the connector's own page artifacts (URL + title).
+
+Note also: `pdf_template_unknown` is a *separate*, much smaller skip on the
+statements→PDF path. It is NOT the cause of the 2-of-4 transactions gap, and
+chasing it would have fixed nothing.
+
+**Fix:** navigate through the offer once, using the interstitial's own `goto`
+param when it names a USAA account-detail route (off-host or wrong-section
+`goto` values are refused, so a redirect chain cannot steer the connector).
+Session death is re-checked *after* the hop, because an offer page can itself
+bounce to logon — that must surface as session-dead (which triggers re-auth),
+never as a missing affordance.
+
+**Watch for:** other banks doing the same thing. A promotional interstitial in
+front of an account page is a generic pattern, and the failure mode it produces
+— "the source changed its UI" — is maximally misleading.
+
+## D2 — a gap-opening path with no gap-closing path (general defect class)
+
+USAA `statements` simultaneously reported:
+
+- stream fact: `covered 10 / considered 10, checkpoint: committed`
+- gap table: **4 rows still `pending`**, three with `attempt_count = 0`
+
+Both readings were current. They disagreed because the four "pending"
+statements were not missing at all — every one has a durable `pdf_sha256` on its
+record. They had been downloaded.
+
+### The class
+
+A pending detail gap leaves `pending` **only** on an explicit
+`DETAIL_GAP_RECOVERED` (`connector-detail-gap-store.ts`). Nothing closes one
+implicitly: not a later success, not a full-coverage `DETAIL_COVERAGE`, not a
+committed checkpoint.
+
+USAA emitted that message for `transactions`
+(`recoverServedAccountTransactionGaps`) and for both credit-card streams —
+**but never for `statements`**. So the first statement PDF that ever failed to
+download opened a gap that no subsequent run could close, however many times it
+succeeded afterwards. Three of the four were never even re-attempted.
+
+> **The general shape: any stream with a gap-OPENING path but no matching
+> gap-CLOSING path accumulates permanent false gaps.** It is silent — the stream
+> looks fully collected on every axis except the gap table — and it is
+> self-inflicted, needing no source misbehavior at all.
+
+**Worth auditing across every connector**: for each stream that can emit
+`DETAIL_GAP`, confirm a `DETAIL_GAP_RECOVERED` path exists and is reachable.
+The asymmetry within a single connector (USAA had closers for 3 streams and not
+the 4th) suggests these are added per-stream as each is built, so the omission
+is easy to repeat.
+
+**Fix:** `emitStatementCoverage` now emits recovery for each served gap whose
+statement is hydrated this run, driven by `coverage.hydratedKeys` — the same set
+that feeds the coverage numerator, so recovery and coverage cannot drift apart.
+
+## D3 — Gmail `message_bodies` has no denominator: PROHIBITED, not unimplemented
+
+Definitive answer to the owner's direct question ("are you sure it's not
+possible?").
+
+`manifests/gmail.json` declares `message_bodies` with `state_stream: "messages"`,
+making it a **static single-parent detail stream** whose checkpoint status is
+projected from the parent's own commit outcome. `runtime/index.ts:1514`
+(`validateDetailCoverageAgainstManifest`) **throws and fails the entire run** if
+such a stream emits `DETAIL_COVERAGE`. This is not a missing feature; emitting a
+denominator is an error.
+
+The owner's reasoning is sound but lands one level off. The message count *is*
+knowable — but it is the **parent's** number. Reporting it under
+`message_bodies` would assert `covered == considered` for bodies that were
+skipped or whose fetch failed. A real denominator would require a per-key
+hydration tally, which this stream does not produce.
+
+`attachments` is the instructive contrast: it has no `state_stream`, and it
+earns coverage from a genuine attempt-per-key tally — which is exactly why it
+is permitted to emit at all.
+
+Already corrected in-tree (`cfe738071`); live evidence shows `collected: 4,
+checkpoint: committed` with no fabricated coverage.
+
+## D4 — Gmail `attachments` "won't backfill": a forged impossibility proof
+
+The 32 terminal `too_large` gaps are **all collectible**. None is genuinely
+oversized.
+
+Gmail's hydrator briefly sized attachments from imapflow's `meta.expectedSize`,
+populated from the FETCH `RFC822.SIZE` item — the size of the **entire message**,
+identical for every part of a multipart message. Against a per-part cap this
+condemned every attachment of a message whenever their SUM crossed it.
+
+The durable signature, straight from the rows:
+
+| claimed "observed" | sum of that message's parts | largest single part |
+|---|---|---|
+| 32,229,094 | 32,218,046 | 7,711,218 |
+| 30,062,404 | 30,051,218 | 8,709,138 |
+| 29,830,196 | 29,800,496 | 10,947,340 |
+
+32 gaps, only **7 distinct claimed sizes** (real per-part sizes are never
+byte-for-byte identical across distinct attachments); every claim ≈ the sum of
+its message's parts; the smallest condemned item is **3,080 bytes** against a
+26,214,400-byte cap.
+
+The connector was fixed (`1bf3f6cfa`, per-part BODYSTRUCTURE size), but the rows
+already written stayed terminal, and `isProvenUnfillableGap` reads
+`observed > limit` as durable per-item proof — so the false verdict outlived the
+defect that produced it.
+
+> **Transferable lesson: a durable "proof" is only as good as the measurement
+> behind it.** `too_large` was treated as unfalsifiable because a size beats a
+> retry count as evidence. But the number itself came from a buggy source, and
+> nothing re-checked it against the item's own recorded size. Any terminal state
+> justified by a recorded measurement should be falsifiable by independent
+> evidence.
+
+**Fix:** `classifyTooLargeProof` adjudicates a row against the item's OWN size —
+requeue only on positive contradiction (`fabricated_proof`); keep terminal for
+`proof_holds`, `no_corroborating_record`, and `not_a_size_proof`. Absence of
+contradiction is not proof of fabrication.
+
+Repair tool: `scripts/repair/requeue-fabricated-too-large-detail-gaps.ts`
+(gmail/attachments-locked, dry-run by default).
+
+**APPLIED 2026-08-22** to `cin_12407c1afb78d56848fe0b20`, with backup table
+`gmail_gaps_backup_20260822034236` (32 rows):
+
+| | before | after |
+|---|---|---|
+| `recovered / temporary_unavailable` | 10,236 | 10,240 |
+| `terminal / too_large` | **32** | **0** |
+| `terminal / quarantined` | 3 | 0 |
+| `pending / temporary_unavailable` | 0 | 31 |
+
+All 32 adjudicated `fabricated_proof` (0 `proof_holds`, 0
+`no_corroborating_record`). The 3 `quarantined` rows went through the existing
+allowlisted tool in the same pass. **Zero terminal gaps remain.**
+
+Recovery is confirmed real, not hollow: within a minute, 4 of the 32 had already
+moved to `recovered` with `hydration_status: hydrated` and content-addressed
+blobs (2,248 / 13,162 / 220,273 / 1,970,646 bytes) — every one far under the cap
+it had been condemned against. So the requeued gaps ARE picked up by the ordinary
+recovery path; this is not the D2 defect class inverted.
+
+Each requeued row carries an audit trail
+(`class: "too_large_proof_contradicted"`) recording the claimed size, the cap,
+and the item's real size, so the repair is legible in the row's own history.
+
+
+## Operational: a repair CLI that silently misread its own arguments
+
+Found while applying the D4 repair. `--reason too_large` (space-separated)
+parsed as `reason = "true"`: the parser read a value only from `--key=value` and
+substituted the boolean `true` otherwise. The operator saw
+
+    --reason='true' is not requeueable (allowed: quarantined, ...)
+
+naming a value they never typed. The refusal was correct — `too_large` IS
+refused by that tool by design — but the message pointed at the wrong thing, so
+the tool looked broken in a different way than it was, and the real routing
+(use the adjudicating tool) stayed hidden.
+
+Both repair CLIs now accept `--flag value` and `--flag=value`, and REFUSE a
+value-taking flag given no value rather than defaulting. Defaulting is what
+produced the defect; failing closed is the only safe reading of an ambiguous
+argument list for a tool that writes to production.
+
+> **Worth checking in other operator tooling:** the `--key=value`-only parser
+> with a `true` fallback is a common hand-rolled shape, and it fails silently
+> and specifically on the argument form most operators type first.

+# Who owns a connector's native sidecar once connectors leave the server repo?
+
+**Status:** intake. No requirement proposed. Written from evidence produced while
+shipping the Signal connector on 2026-08-17.
+**Date:** 2026-08-17
+
+## The question
+
+Several connectors shell out to a native binary they do not own:
+
+| connector | sidecar | license | how it ships today |
+|---|---|---|---|
+| slack | `slackdump` v4.4.2 | AGPL-3.0 | pinned tarball, SHA256-verified, builder stage in the RI `Dockerfile` |
+| google_messages | `gmcli` | — | same arms-length-subprocess pattern |
+| signal | `sigtop` v0.24.0 | ISC | built from pinned source in a Go builder stage (added today) |
+
+All three live in the **reference implementation's** `Dockerfile`. If connectors move
+into their own distribution — the data-connectors reorg — that stops working: a
+connector shipped separately cannot edit the server's image build.
+
+So: **how does an independently-distributed connector declare and obtain a native
+dependency, and who verifies it works on the runtime that will actually execute it?**
+
+## Evidence from shipping sigtop today
+
+Seven build failures, in order. Every one was caught before shipping, but the pattern
+matters more than the count:
+
+1. `golang:1.23` too old — sigtop needs Go ≥ 1.25
+2. missing `libsecret-1-dev` at build time
+3. license file is `LICENSE.md`, not `LICENSE` or `COPYING`
+4. **`libsecret-1.so.0` missing at runtime** — binary compiled cleanly, could not load
+5. **GLIBC 2.38 vs 2.36** — `golang:latest` is Debian trixie, the runtime image is
+   bookworm; the binary ran in the builder and died in the final image
+6. `sigtop -v` is not a valid subcommand
+7. `sigtop version` is not either
+
+**4 and 5 are the load-bearing ones.** Both produced a binary that built successfully
+and would have failed on the owner's first real sync. Neither is discoverable from the
+connector's own source; both are properties of the *runtime image* the connector will
+be executed in.
+
+That is the crux. A connector author can pin a version and a checksum. A connector
+author cannot know the runtime's glibc, its installed shared libraries, or its
+architecture — and today's evidence says those are exactly what break.
+
+## What the current pattern gets right
+
+Worth preserving whatever the packaging answer is:
+
+- **Pinned version + SHA256** on the downloaded artifact (`slackdump`), or a pinned
+  source tag with a commit-exact `SOURCE_URL` recorded (`sigtop`).
+- **Isolated builder stage** — Go and build dependencies never reach the final image.
+- **License and corresponding-source URL copied into the image**, which AGPL §6(d)
+  requires for `slackdump` and is good practice for ISC.
+- **Build-time smoke test.** `slackdump version` and (now) an execute-and-check for
+  `sigtop`. This is what caught failures 4 and 5. A verification step written as
+  `... || true` would have shipped both.
+
+## Options, none yet chosen
+
+**A. Connector declares, runtime resolves.** The manifest names a sidecar (source, pinned
+version, checksum, license) and the runtime image build reads those declarations and
+produces the binaries. Keeps one place that knows the runtime's glibc and libraries.
+Cost: the runtime build must enumerate every connector, which partially re-couples what
+the reorg is trying to separate.
+
+**B. Connector ships prebuilt per platform.** Each connector distributes its own
+binaries for supported platform triples; the runtime verifies checksum and executability
+on load. Fully decoupled. Cost: connector authors take on cross-compilation and a
+platform matrix, and today's evidence says that is precisely where the failures live.
+
+**C. Sidecar declared as a runtime prerequisite.** The connector declares "requires
+`sigtop` ≥ 0.24 on PATH" and refuses to register when absent, with a clear message. Zero
+packaging burden, but it breaks the property that makes the current product good — a
+self-hoster following the docker/railway/fly.io steps gets working connectors with no
+extra install. Slack works today because `slackdump` is *in the image*.
+
+## The constraint any answer must satisfy
+
+**Whatever ships must be verified against the runtime it will execute on, at build time,
+by executing it.** Not "the artifact downloaded," not "the checksum matched" — those both
+passed today while the binary was unrunnable. The only check that caught it was running
+the thing.
+
+## Open questions
+
+- Does the reorg keep a single runtime image, or do connectors get their own containers?
+  Option B is much more attractive in the latter case.
+- Is there an existing prior-art answer here? Language package managers with native
+  extensions solve a similar problem (Python wheels' manylinux, Node prebuilds), and
+  manylinux exists specifically because of the glibc problem hit today. Worth a sweep
+  before designing.
+- How does a self-hoster on a non-Debian base fare today? Untested — the current
+  `slackdump`/`sigtop` stages both assume Debian.
+
+## Related
+
+Same shape as the collector/server contract gap
+(`upstream-disclosure-window-2026-08-17.md` and the collector-contract findings): a
+component whose correctness depends on a peer's version, with nothing verifying the pair
+is compatible. Here the failure is loud at build time if a smoke test exists, and silent
+until first use if it does not.
+
+---
+
+## Proposed requirement (appended 2026-08-17 after prior-art research)
+
+Research: `~/.tmp/reorg-0814/sidecar-abi-prior-art.md` (corpus entry filed). Key finding:
+manylinux, Node prebuilds, and N-API all declare compatibility as data and verify by static
+analysis or eliminate the variable by construction — **no surveyed ecosystem executes the
+artifact on the real target before accepting it**. The constraint this note demanded is a
+genuine gap in prior art; adopting it puts this registry ahead of, not behind, the state of
+the practice.
+
+Direction (option B, shaped by the registry design; proposed, not owner-ratified):
+
+1. **Static by default** — `CGO_ENABLED=0`/musl-static for any sidecar without a real
+   `dlopen` dependency; erases the glibc class by construction (verify per-tool, don't assume).
+2. **ABI tags where dynamic is unavoidable** — per-artifact `{os, arch, libc, libc_floor,
+   linkage}` (manylinux/prebuildify model), built inside a pinned deliberately-old shared
+   build image (the registry's manylinux-image equivalent), so the floor is infrastructure,
+   not per-author judgment.
+3. **`smoke_cmd` becomes a manifest/artifact field** — the trusted installer executes it on
+   the actual runtime at install time and refuses on failure; loader errors already
+   distinguish "missing library" from "symbol too new" with no parsing.
+4. **Graceful fallback** — on smoke failure, try the static/alternate build before failing
+   the connector.
+
+Why not options A/C: A cannot survive in-app connector install (no image rebuild available
+at user install time) — transitional-only by construction; C breaks the self-hoster
+works-out-of-the-box property this note already names.
+
+Transitional: today's Dockerfile builder stages are server-repo property, untouched by the
+connector-content move; recorded as a known coupling whose removal trigger is registry
+artifacts carrying ABI-tagged (or per-connector-container) sidecars. For server deployments
+the container sandbox tier ultimately makes the sidecar ABI self-contained inside the
+connector's own image; the tag machinery chiefly serves bare-metal desktop.
+
+---
+
+## The packaging rule (settled 2026-08-17, window 20 disposition)
+
+**Sidecar packaging keys off the connector's placement bindings, not one uniform
+mechanism.**
+
+- **Network-authenticated sidecars** (`slackdump`) belong in the server's runtime image.
+  The tool reaches the provider over the network, so the server is a legitimate place to
+  run it, and the builder-stage pattern above is the right answer.
+- **Session-bound sidecars** (`sigtop`) can only be acquired to the *user's* machine.
+  No server-side image stage can help, because the constraint is not where the file is —
+  it is where the key can be unwrapped.
+
+That sentence is what makes the rest of this note cohere, and it is why "put the binary in
+the image" was the wrong instinct for Signal.
+
+### Evidence: Signal cannot run server-side, by construction
+
+Tested against real data on this host, four successive configurations:
+
+| attempt | result |
+|---|---|
+| container, no mounts | `open /root/.config/Signal/sql/db.sqlite: no such file` |
+| + Signal data mounted read-only | `cannot decrypt database key: cannot connect to D-Bus session bus` |
+| + host `/run/user/1000/bus` mounted | `EOF` (uid mismatch) |
+| + `--user 1000:1000` | `An AppArmor policy prevents this sender from sending this message` |
+
+`~/.config/Signal/config.json` holds `encryptedKey` with `safeStorageBackend: kwallet6`
+and no plaintext key. Mounting the database is insufficient because **the key is not in
+the file** — it unwraps only through a session-bound keyring daemon.
+
+### Consequences adopted
+
+1. **Signal ships local-collector-only**, with a PATH/`SIGTOP_BIN` resolution and a clear
+   install error as the interim acquisition story. Connector code must not fetch
+   executables at runtime; a downloader in the npm package today would be the insecure
+   version of the signed, ABI-tagged registry artifacts already designed above.
+2. **The constraint is now declared, not discovered.** `desktop_session` is a
+   first-class binding in `runtime_requirements.bindings`, and
+   `sourceKindFromManifestBindings` resolves it to `local_device` — the same placement
+   mechanism that already keeps browser connectors off the collector profile. The engine
+   refuses server-side placement up front rather than failing four D-Bus layers deep.
+3. **The `sigtop` builder stage is removed from the Core image.** Shipping a binary that
+   cannot work there implies support that does not exist. The builder-stage pattern
+   remains proven via `slackdump`.
+
+### Edge case worth documenting, not shipping for
+
+Signal Desktop configured with `safeStorageBackend: basic_text` stores the key
+**unwrapped**, so a server-side path does exist for users who have disabled their keyring.
+That is a documentation note, not a reason to carry an image stage — and a connector that
+declares `desktop_session` should keep declaring it, since the common configuration is the
+session-bound one.
+
+### Carry-through
+
+The connector fleet was copied to `data-connectors` around this change. The manifest and
+engine edits above were made in pdpp's canonical copy and **must be carried through the
+cutover rather than silently diverging.**

+# Detecting a cursor a connection never earned
+
+**Status:** deferred. Code removed from the branch; no requirement is proposed yet.
+**Date:** 2026-08-20
+
+## What was built, and why it is not in the tree
+
+`reference-implementation/runtime/cursor-provenance.ts` and its test were removed from
+`fix/sweep-fairness-and-transformer-bounds` before that PR landed. The module was never wired into
+anything: its only reference anywhere in the repo was its own test file, and it does not exist on
+`main`. Its own commit (`6af425709`, "detect the three ways a cursor silently excludes data") says
+so deliberately — it "stays unwired: it needs the full connection set, so it belongs in the
+maintenance sweep rather than the per-run commit."
+
+Unwired, it still failed the zero-connector-knowledge conformance gate, because its watermark table
+names eleven connectors in RI production source. That is a real gate finding, not a false positive.
+Shipping the module unwired bought nothing and blocked a PR carrying real production fixes, so the
+code came out and the analysis stays here.
+
+This note exists so the next person does not rediscover the defect, the ruling, or the blocker.
+
+## The defect: `duplicate_of_sibling`
+
+A watermark cursor ("fetch everything newer than T") is only sound when T was reached by *this*
+connection walking its own history. Seed a new connection with another connection's high-water mark
+and every record older than T becomes permanently unreachable — the connection will only ever ask
+for newer items — while `covered == considered` keeps reporting complete coverage, because the run
+genuinely did process everything it fetched.
+
+This is live, not hypothetical. ChatGPT connection `cin_484604984db7c091bd08b259` (created
+2026-08-17) held a `conversations` cursor of `2026-06-19T20:30:04.127Z`, byte-identical to the
+millisecond to the cursor of a different, paused connection (`cin_e4ab231c7d49b8f59e4c80ed`) that
+reached that value on its own final run. Two separate accounts do not independently walk to the same
+millisecond. The value was copied, and everything older than it is unreachable for the newer
+connection.
+
+The signal is exact equality across sibling connections for the same connector and stream, never
+proximity and never staleness. Staleness is explicitly not evidence: an account nobody has posted to
+in six months has a legitimately frozen watermark, and firing on it would cry wolf on exactly the
+quiet connections an owner is least able to check by hand.
+
+A finding is `suspected`, never a quantified loss. The evidence proves the cursor's *provenance* is
+unsound, which makes any completeness claim built on it unfounded; it does not measure how much data
+is unreachable. The right outcome is to withhold the healthy claim and tell the owner to re-seed.
+
+One rule was tried and disproved by the live fleet: flagging a cursor that predates its own
+connection's `created_at` produced seven false positives across reddit, github, and notion. Those
+watermarks store the newest *content item's* timestamp, not an observation time, so a connection
+created today that fully walks an account whose newest post is from 2024 correctly stores 2024. The
+rule was removed rather than tuned.
+
+## The ruling: this audit stays RI-owned
+
+The architecture owner's decision, which this note records so it is not relitigated: the watermark
+specs must NOT move into connector manifests, unlike the sibling `cursor-band-contiguity` check
+whose `cursor_shape` enum did move.
+
+Letting a connector declare which of its fields are checkable lets the audited party define the
+audit's scope. A connector could omit or mis-path its watermark and silently exempt itself, or
+mis-declare `valueKind` (`iso8601` as `epoch_seconds`), making comparisons meaningless with no
+error raised. This is an integrity check *about* the connector evaluated *against* the connector,
+so the connector cannot be the one who says what counts.
+
+The contrast with `cursor-band-contiguity` is the useful part. There, the manifest declares only a
+closed enum (`cursor_shape: "imap_uid_band"`) and the RI owns every semantic — the paths, the
+`UIDVALIDITY` epoch guard, the arithmetic. Declaring can only opt a stream *in*; omission yields
+silence, never a healthy verdict. That asymmetry is what makes manifest declaration safe there and
+unsafe here.
+
+## The blocker: the sibling-JSON route fails both ways
+
+The obvious fix — move `WATERMARK_SPECS` into an RI-owned JSON data file (e.g.
+`reference-implementation/data/watermark-specs.json`) and load it at runtime, keeping the data
+RI-owned rather than connector-declared — does not work. It was tried and probed empirically against
+the real scanner, not just reasoned about. Both halves of rule 5 reject it:
+
+1. **The path.** `SANCTIONED_POLICY_RESOURCES` in
+   `reference-implementation/test/helpers/ri-zero-connector-knowledge-data-load-scan.ts` is
+   deliberately an empty `Map`. Its own doc records that the two production files which used to load
+   a sibling RI-owned registry through it (`compact-record-history.ts`, `version-disposition.ts`)
+   were migrated *away* on purpose. A probe file loading such a JSON returns
+   `unsanctioned-policy-resource-path`.
+
+2. **The content.** Even with an allowlist entry, `classifySanctionedPolicyResource` parses the
+   file and walks it for any string — object key, value, or array element, at any depth — equal to a
+   manifest-derived connector key, reporting `hardcoded-connector-literal-in-ri-owned-json`. A
+   watermark-spec file is nothing but connector keys, so it fails here even if the path were
+   sanctioned.
+
+The scanner states the principle directly, and it is correct: moving a connector-identity fact out
+of `.ts` source into a sibling RI-owned JSON file "is exactly as much self-attested connector
+knowledge as the literal it replaced, reached via a different seam."
+
+Adding an allowlist entry to get past this would be defeating a gate that is working as designed,
+not satisfying it.
+
+## The viable path
+
+Wire the check into the **maintenance sweep**, with the watermark specs supplied by the call site
+rather than held as a module-level table in RI production source.
+
+This fits the shape of the check anyway. `evaluateCursorProvenance` needs the full set of
+connections for a connector/stream to compare siblings, which is a sweep-time input, not a per-run
+one — the reason the original commit left it unwired. Making the specs a parameter means the pure
+comparison logic stays RI-owned and connector-agnostic, and the identity table lives wherever the
+sweep legitimately assembles per-connector context.
+
+That is a real design task with its own review surface: where the sweep gets the specs, whether a
+finding withholds a healthy verdict or only annotates, and how `suspected` is surfaced to an owner
+without implying a measured loss. It deserves its own PR rather than being rushed to unblock CI.
+
+Recovering the code: `git show 6af425709 -- reference-implementation/runtime/cursor-provenance.ts`
+(and the sibling test path). The module and its 9 tests were passing when removed; only the
+conformance gate objected, and only to the identity table.

+# A failure must not destroy its own cause
+
+**Status:** intake. No requirement proposed. Written from five production
+failures observed on 2026-08-18, two of them fixed the same day.
+**Date:** 2026-08-18
+
+## Why this note exists
+
+Five failures in about one day. All five have the same shape: **something went
+wrong, and the evidence needed to act on it was destroyed by the code that
+handled it.** In four cases the failure itself may well have been transient and
+harmless. What made them cost a day was that nothing downstream could tell.
+
+1. **`[object Object]`.** `packages/polyfill-connectors/src/reference-blob-uploader.ts`
+   built its error text with `String(body.error ?? statusText)`. The RI host
+   always shapes `error` as an object — `pdppError` in
+   `reference-implementation/server/request-helpers.ts:92` writes
+   `{code, message, type}` — so `String()` produced the literal
+   `"[object Object]"` for every host-side failure. That discarded the cause of
+   24 quarantined Gmail attachment gaps, each recorded as
+   `blob upload failed (503): [object Object]`. Fixed in `457e23e93`.
+2. **Silent statement_timeout.** `observeConnectorSummaryEvidence`'s outer catch
+   treated a typed `PostgresStatementTimeoutError` like any other error and
+   routed it to `markAllConnectorSummaryEvidenceDiscoveryFailed`, durably
+   writing `record_snapshot_state='failed'` across every row in scope. Neither
+   that path nor `repairCandidatePostgres` logged anything. 25 of 29 evidence
+   rows degraded in production with **zero** log output. Fixed in `1d8995b0f`.
+3. **Empty `failure_reason`.** A failed ChatGPT run (`run_1787075769450`) wrote
+   zero log lines matching its own `run_id`, and `run_history.failure_reason` is
+   empty on every failed row. Only `terminal_reason` and a
+   `connector_error_json` blob survived. Not fixed.
+4. **`[REDACTED]`.** HEB connection `cin_c875ca3ec8b6ce2c283a4288` failed with
+   `connector_error_json = {"code": null, "message": "heb_session_failed: [REDACTED]", "retryable": false}`.
+   The cause is literally the string `[REDACTED]`. Partly fixed same-day in
+   `46887c2e8`, which populates the `code` channel; the `message` channel is
+   the subject of the proof-of-concept below.
+5. **Unpublished dependency.** Every published `@pdpp/local-collector`
+   (1.5.1–1.5.4) has `import ... from "@pdpp/reference-contract/common"` as line
+   1 of `dist/polyfill-connectors/src/local-device-client.js`, but that package
+   is not in `dependencies` and does not exist on npm. Every install crashes
+   with `ERR_MODULE_NOT_FOUND` on any invocation, including `--version`. It
+   works in the monorepo because pnpm resolves it through the workspace link.
+
+Numbers 1–4 are error handling. Number 5 is packaging, and it belongs to a
+different family; it is addressed separately at the end.
+
+## First, the scale numbers are wrong
+
+The intake for this note claimed ~246 bare catches and ~282 stringified-error
+coercions. Both were re-measured. The raw catch count is **higher** than
+claimed and the story is **much smaller**.
+
+| metric | intake claim | measured |
+|---|---|---|
+| bare `catch {` (non-test) | ~246 | **439** |
+| bare `catch {` (tests, separate) | — | 207 |
+| `catch (e) {}` empty body (non-test) | — | **0** |
+| `String(err)`-style on error-named values | ~282 | **173** |
+| `REDACTED` (non-test, in scope) | ~58 | 35 |
+
+The original grep almost certainly used `catch\s*\{`, which also matches
+`catch (e) {`. It conflated two populations while undercounting the one it
+named.
+
+Then 55 of the 439 bare catches were read and classified, one per file, across
+55 distinct files:
+
+| class | count | share |
+|---|---|---|
+| benign cleanup | 8 | 15% |
+| benign optional parse | 24 | 44% |
+| benign probe | 21 | 38% |
+| **fault-swallowing** | **0** | **0%** |
+| **degrades durably** | **2** | **3.6%** |
+
+**About 97% of bare catches are benign, and the fault-swallowing class is
+empty.** The dominant patterns are `JSON.parse` → `return null` on stored
+manifests and cursors, `new URL(x)` → `return false` in SSRF validators, and
+telemetry taps explicitly commented "must never break the streaming path."
+Several carry a comment justifying the swallow. This is a deliberate house
+style, not neglect. **There is no catch-block crisis here, and a campaign to
+migrate 439 call sites would be almost entirely waste.**
+
+What the sample did find is three real defects, verified end-to-end to their
+persistence points:
+
+- `packages/polyfill-connectors/src/statement-content-fingerprint.ts:142` —
+  any PDF text-extraction failure returns the all-null fingerprint, which is
+  then persisted as statement `content`. The record durably says "no extractable
+  content" whether the PDF is genuinely empty or the extractor crashed. USAA's
+  sibling path at `statement-pdfs.ts:502` shows the fix: it emits `onSkip` with
+  `structuralErrorDiagnostic(err)`.
+- `packages/polyfill-connectors/connectors/gmail/index.ts:1418` — an IMAP body
+  fetch failure returns null bodies and the message is emitted anyway, with no
+  `DETAIL_GAP` and no coverage marker. Given the measured ~4.65 KB/s IMAP
+  throttle on this connector, transient failures are expected, so bodyless
+  messages land durably with nothing distinguishing them from empty mail.
+- `reference-implementation/server/routes/as-grant-revoke.ts:157` —
+  `String(e?.message ?? hookErr)`, where the catch neither rethrows nor changes
+  the response. A failed grant-revoke side effect vanishes into one unreadable
+  log line while the caller gets a success envelope.
+
+Both durable-degradation sites are the same shape: **a fail-closed default that
+is indistinguishable from a legitimate empty result.** Neither needs a `try`
+restructured; each needs one extra field saying why the value is null.
+
+The `457e23e93` archetype has **no surviving siblings** — a targeted search for
+`String(...)` over parsed-JSON HTTP error bodies returns zero hits. And all 35
+`REDACTED` occurrences are redaction *mechanism* (regex constants, scrub tables,
+sanitizers), not a bare `message: "[REDACTED]"` standing in for a lost cause.
+
+So the honest headline is **three fixes, not 246.** The rest of this note is
+about why those three happened and what makes the next one impossible.
+
+## What this codebase already gets right
+
+There is a good, half-built convention here, and it is worth naming precisely
+because the answer is to finish it rather than import something foreign.
+
+**Two channels with opposite disciplines.** Stated outright in
+`packages/polyfill-connectors/src/terminal-error.ts:44-57` and implemented once,
+correctly, in `buildTerminalConnectorFields`
+(`reference-implementation/runtime/index.ts:2846`):
+
+- `code` is a **typed** channel. It is *validated, never redacted*, and fails
+  closed to null. `boundConnectorErrorCode` tests it against
+  `/^[a-z][a-z0-9_]{1,63}$/` and drops anything malformed.
+- `message` is a **prose** channel. It is *redacted and truncated*, never
+  trusted — `boundConnectorErrorMessage` runs `redactStderrTail` then caps at
+  500 characters.
+
+The security argument for the asymmetry is explicit in the source: `code` is
+exempt from redaction *only because* the charset makes it incapable of carrying
+a credential, a URL, or a stack trace. That is a genuinely good design, and it
+is the thing to generalize.
+
+Three more pieces are already right:
+
+- **`recovery_hint` is a closed vocabulary** of 8 actions
+  (`runtime/connector-gap-bounding.ts:117`), with the design intent stated
+  well: *"a connector requests an ACTION this way; it never gets to pick one by
+  shaping its `code` or free-form `message` text."*
+- **Structured failure evidence on the row.** `search_index_dirty` records
+  `last_error`, `attempts`, and `next_attempt_at` atomically
+  (`queries/search/index-dirty/record-failure.sql`), with the comment
+  *"observable evidence, not just a console.warn line."* This is the right
+  instinct and the right place to put it.
+- **The typed-error → reason-code mapping** the `1d8995b0f` fix introduced:
+  `err instanceof PostgresStatementTimeoutError ? REASON_CODES.STATEMENT_TIMEOUT : default`.
+  That is exactly the shape the terminal design needs, written once.
+
+### Where the convention is only half-built
+
+The pattern exists. Its *closure* does not.
+
+- **Closure is upheld by hand-copied `Set`s and tests, not by types.**
+  `RECOVERY_ACTIONS` is a `Set<string>`. Both `REASON_CODES` objects are
+  unexported `as const` with no derived type. `codeToStatus`
+  (`routes/ref-error-status.ts:89`) is `Record<string, number>`, so an
+  unregistered error code compiles fine and silently becomes a 500. Only
+  `SharedConnectionConditionReason` is a real derived union — and it is the one
+  vocabulary with a single producer and a single consumer.
+- **It has already drifted.** `scripts/stream-health-audit/authority.ts`
+  maintains duplicate `Set`s that omit `repair_statement_timeout` and contain
+  `"summary_evidence_unavailable"`, which exists in no const.
+  `"update_connector"` is emitted at `runtime/connection-health.ts:1982,2747`
+  and is not in `RECOVERY_ACTIONS`.
+- **~170 error subclasses, no shared base.** The de-facto common field is
+  `code: string`, but the HTTP-status carrier is variously `statusCode`,
+  `httpStatus`, and `status`. Discrimination splits three ways: 134 `instanceof`
+  sites, 74 `.code ===` sites, and 3 fragile `.name === "..."` string
+  comparisons.
+- **The typed channel degrades into prose-sniffing.** When a recovery hint is
+  absent or invalid, `inferRecoveryAction`
+  (`runtime/connector-gap-bounding.ts:739`) regex-matches the free-form message
+  to guess an action. `connector-coverage-policy.ts:167` matches connector
+  reason strings by substring. These are the seams where a structured design
+  silently becomes a guess.
+- **There is no logger.** No module exports a log API. Pino exists but is wired
+  to exactly one call site (`transport.ts:335`) and is never exported, so no
+  library module can reach it. Everything else is `console.*` with a
+  `[module-tag]` prefix — **19 calls in the entire server, none carrying
+  `run_id`.** That is the mechanical reason incident 3 produced zero lines
+  matching its own run id: there is no facility that would have written one.
+  The real correlation channel is the spine (`lib/spine.ts:483`), which carries
+  `run_id`, `trace_id`, `request_id`, and `grant_id`, and hard-rejects a
+  malformed event. `packages/polyfill-connectors/src/` has no spine access at
+  all, which makes it the least observable surface in the system.
+
+## The invariant
+
+The candidate invariant from intake was:
+
+> A failure must never lose the information needed to act on it. Every failure
+> that crosses a durability boundary carries a machine-readable code, a
+> human-readable cause that is not a stringified object, and a PII-safe
+> diagnostic detail. A catch that discards a fault is a bug, not a style choice.
+
+The last sentence should go. The measurement says the fault-swallowing class is
+empty and 97% of bare catches are correct, so "a catch that discards a fault is
+a bug" indicts a house style that is not what broke. It would also push toward
+a 439-site migration that buys nothing.
+
+The rest is close but describes a payload rather than a property. What actually
+failed in all four cases is narrower and more testable:
+
+> **A failure that crosses a durability boundary must carry a cause that is
+> reconstructable from what is written down.** Every failure persisted to a row,
+> returned to a caller, or shown to the owner carries (a) a machine-readable
+> code from a closed vocabulary, and (b) a human-readable cause. Any transform
+> applied on the way out — coercion, redaction, truncation, classification —
+> must be **category-preserving**: it may drop detail, but it may never leave a
+> value whose failure class can no longer be told apart from a different one.
+
+The operative word is *category-preserving*. `[object Object]`, `[REDACTED]`,
+`''`, and `record_snapshot_state='failed'` with no reason are all the same
+defect under this rule: each is a value that survived the boundary while
+becoming indistinguishable from every other failure that produced the same
+placeholder.
+
+### Testing it against the five incidents
+
+| # | prevented? | why |
+|---|---|---|
+| 1 `[object Object]` | **yes** | The coercion is not category-preserving: every distinct host error maps to one string. Caught by the rule directly. |
+| 2 silent timeout | **yes** | A cancelled read and a genuinely bad row both wrote `failed`. Distinguishing them is exactly what `1d8995b0f` added, and it is what the rule requires. |
+| 3 empty `failure_reason` | **partly** | The rule forces the field to be populated. It does **not** by itself produce a correlated log line — that needs a logger this codebase does not have. |
+| 4 `[REDACTED]` | **yes** | Redaction that collapses distinct reasons to one token is not category-preserving. |
+| 5 unpublished dep | **no** | Nothing was mishandled. No failure crossed a boundary; the artifact never ran. Different family. |
+
+**Where it would not have helped, honestly:**
+
+- It would not have prevented incident 5 at all.
+- For incident 3 it fixes the durable row but not the missing log. Someone
+  debugging by `grep run_id` still finds nothing until a logger exists.
+- It says nothing about failures that are never caught in the first place, or
+  about a correct code attached to a wrong diagnosis.
+- It does not address the two durable-degradation sites found by measurement
+  (`statement-content-fingerprint.ts:142`, `gmail/index.ts:1418`). Those write a
+  *successful-looking record* with a silently-null field; no failure crosses a
+  boundary, so the invariant never engages. They need a different rule — a
+  fail-closed default must be distinguishable from a real empty result — and
+  that rule is worth stating separately rather than stretching this one.
+
+## The mechanism
+
+One small thing, not a framework. The two-channel design already exists and is
+already correct; what is missing is that its vocabularies are open and its
+transforms are not category-preserving. Three changes, in order of leverage.
+
+**1. Close the vocabularies with types, not `Set`s.** Every reason vocabulary
+becomes an exported `as const` with a derived union:
+
+```ts
+export const RECOVERY_ACTIONS = {
+  RETRY_BY_RUNTIME: "retry_by_runtime",
+  // ...
+} as const;
+export type RecoveryAction = (typeof RECOVERY_ACTIONS)[keyof typeof RECOVERY_ACTIONS];
+```
+
+This is a mechanical change with immediate payoff: `"update_connector"` and the
+drifted audit `Set`s become type errors rather than silent divergence, and
+`codeToStatus` stops turning an unregistered code into a 500 by default. It
+requires no call-site migration — only the declarations move.
+
+**2. Make redaction category-preserving.** This is the subject of the
+proof-of-concept below, and the finding there is the most interesting result in
+this note.
+
+**3. Populate `failure_reason` from the terminal event.** The empty field in
+incident 3 is not a bug in the ordinary sense. It is a hardcoded literal, in
+both backends, with a comment explaining why:
+
+```ts
+// reference-implementation/server/stores/run-history-writer.ts:275 and :366
+const terminalReason = typeof event.data.reason === "string" ? event.data.reason : null;
+const failureReason: string | null = null;
+```
+
+The comment says `failure_reason` is a scheduler-only classification and is
+"left null rather than fabricated, since no Slice A reader depends on it for
+non-scheduled runs." That reasoning was sound when written and is now false —
+`ref-spine-correlations-list` and the console both read it. **This is worth
+dwelling on: the information was dropped deliberately, on a reader-side
+assumption that later stopped holding.** No lint rule catches that. It is an
+argument for making the *durable schema* carry the classification unconditionally,
+so a writer cannot decide on a reader's behalf that a cause is not worth keeping.
+
+### The gate that makes regression impossible
+
+This repo already has the right mechanism, used twice, and it is better than a
+linter rule for this purpose. `lefthook.yml` runs
+`check-direct-prepare-conformance.ts`, which pins grandfathered sites at exact
+`(path, line)` in a checked-in allowlist and fails on three divergences: a
+**new** hit not in the allowlist, a **stale** row whose site moved or was
+migrated, and a **duplicate** row. The polyfill-connectors `noAwaitInLoops` gate
+has the same shape. The comment states the property that matters:
+
+> The rule still fires on any NEW direct-prepare anywhere, INCLUDING a new one
+> inside an already-allowlisted file, and additionally fails on a STALE
+> allowlist row so exceptions cannot be carried silently.
+
+That is precisely the migration mechanism this design needs, and it already
+exists. A new `check-error-envelope-conformance.ts` in the same shape would
+enforce the one defect worth banning outright: **`String(...)` applied to a
+caught value or a parsed HTTP error body.** That is a real, narrow, mechanically
+detectable pattern with exactly one known instance left
+(`as-grant-revoke.ts:157`), so the allowlist starts at ~1 entry rather than 439.
+
+Biome cannot express this. It is version 2.5.6 extending `ultracite`, and the
+repo already works around missing rules with grep gates — the `no-double-cast`
+job exists because "Biome/Ultracite has no equivalent to typescript-eslint's
+`consistent-type-assertions` yet." A `String()`-on-caught-value rule needs type
+information about the argument, which is why the grep gate is the honest answer
+here rather than a stopgap.
+
+**What should not be banned:** empty `catch {}`. The measurement says 97% are
+correct and the fault-swallowing class is empty. A lint rule there would
+generate 439 suppression comments and teach people to ignore the gate.
+
+## Proof of concept: category-preserving redaction
+
+Incident 4 was chosen over incident 3 because another agent is already working
+in `run-history-writer.ts`, and because it turned out to have the more
+interesting answer.
+
+While this note was being written, `46887c2e8` landed a **complementary** fix
+for the same incident from the other side: it populates `TerminalError.code` on
+the session-establishment path, so the *typed* channel carries the reason even
+when the prose channel is destroyed. That is the right first move and it
+confirms the two-channel design is the one to generalize. It does not restore
+the `message`, which is what an owner reads and what `inferRecoveryAction`
+consumes, so the two fixes stack rather than compete. The proof-of-concept below
+touches `runtime/stderr-redact.ts`, which `46887c2e8` does not; both were
+verified green together.
+
+**The defect, reproduced exactly.** `LONG_OPAQUE_RE`
+(`runtime/stderr-redact.ts:43`) is `/\b[A-Za-z0-9_-]{24,}\b/g` — an **entropy**
+heuristic, aimed at unlabelled API keys in stack traces. Categorical reason
+tokens match it too:
+
+```
+"heb_session_failed: login_form_never_appeared"   -> "heb_session_failed: [REDACTED]"
+"usaa_session_failed: source_unavailable"         -> "usaa_session_failed: source_unavailable"
+```
+
+`login_form_never_appeared` is 25 characters and carries no PII whatsoever.
+`source_unavailable` is 18 and survives. **Whether a failure stayed diagnosable
+was decided by the length of its reason token.** Run through the real production
+boundary, `boundConnectorErrorMessage` reproduces the exact production string
+`heb_session_failed: [REDACTED]`.
+
+There is a second half to this. Once the message is destroyed,
+`inferRecoveryAction` regex-matches the *redacted* text to choose a recovery
+action, and returns `"unknown"`. So the redaction did not just cost a human
+reader the cause — it silently degraded the machine-actionable output too.
+
+**The finding: shape cannot fix this.** The obvious fix is a smarter pattern —
+preserve alphabetic `snake_case`, redact anything with entropy. Tested against
+real secret shapes, it separates cleanly:
+
+```
+login_form_never_appeared            kept      sk_live_<redacted-example>   redacted
+heb_verification_code_not_provided   kept      eyJhbGciOiJIUzI1NiIsInR5cCI6...  redacted
+two_factor_challenge_unrecognized    kept      a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6 redacted
+```
+
+And then it fails, in the way that matters:
+
+```
+tim_nunamaker_gmail_com              kept      <- a personal name
+```
+
+**A name is alphabetic snake_case too.** No regex distinguishes a declared
+reason token from a person's name, because the difference is not spelling — it
+is *provenance*. That is the load-bearing conclusion, and it is why the
+mechanism is an allowlist rather than a better pattern.
+
+So: a token survives only if the connector **declared** it in advance. The
+declaration is reviewable in the connector's source, where a human reading
+`login_form_never_appeared` can see it is a constant, and would see a name for
+what it is.
+
+```ts
+// reference-implementation/runtime/stderr-redact.ts
+next = next.replace(LONG_OPAQUE_RE, (match) => (declared?.has(match) ? match : "[REDACTED]"));
+```
+
+The full change is 36 lines, most of it the comment explaining why shape does
+not work. Six tests in
+`reference-implementation/test/stderr-redact-declared-reasons.test.ts` pin the
+four properties the fix must have, including the two that say what it
+deliberately does not do:
+
+```
+✔ regression: the production defect — a declared reason token is destroyed by length alone
+✔ a declared reason token survives redaction, so the owner sees the real cause
+✔ secrets are still redacted even when a declaration set is supplied
+✔ an UNdeclared reason token still redacts — declaration is the safety property, not spelling
+✔ callers that do not opt in are byte-identical to the previous behaviour
+✔ disclosed pre-existing gap: this redactor is not a PII control
+```
+
+**Verification.** 18/18 tests pass across the new file and the existing
+`stderr-redact` suite; 20/20 across `connector-gap-bounding` and
+`device-exporter-sanitize` consumers; 16/16 on the systemic-failure redaction
+and stderr-tail oracles. `tsc --noEmit` clean, `biome check` clean. The
+declaration set is optional and defaults to empty, so every existing call site
+is byte-identical — pinned by its own test, since a redaction change that
+silently widened what escapes would be much worse than the bug it fixes.
+
+**Disclosed while building it.** Today's redactor already passes
+`tim.nunamaker@example.com` and `tim_nunamaker_example` through untouched, with
+no options involved — both are under the 24-character threshold. This is
+pre-existing and independent of the change, but it should be recorded plainly:
+`LONG_OPAQUE_RE` is an entropy heuristic and **is not a PII control**, though
+its name and position invite reading it as one. The declared-token change can
+only ever reduce what escapes, never widen it. Whether a real PII boundary is
+needed here is a separate question this note does not answer.
+
+## Incident 5 is a different family
+
+Nothing was mishandled. No failure crossed a boundary. The artifact simply never
+ran anywhere except where it was built — the same shape already recorded in
+`connector-sidecar-packaging-2026-08-17.md`, which put it well:
+
+> Whatever ships must be verified against the runtime it will execute on, at
+> build time, by executing it.
+
+The pleasant surprise is that **the smoke test already exists and is already
+correct.** `packages/local-collector/scripts/pack-install-run.ts` packs the
+tarball, installs it into a clean temp npm project outside the workspace with an
+isolated `HOME` and cache, and then *executes the installed binary* — `advertise`,
+`enroll`, and `run --connector codex` against an in-process reference server. It
+asserts forbidden packages are absent and the bin is executable. An `npm install`
+of a package whose dependency does not exist on npm fails at the install step.
+**It would have caught this.**
+
+It is wired to `pnpm --filter @pdpp/local-collector run verify`, and `verify` is
+`pnpm test && pnpm validate:package`. `pack-install-run` is not in it. CI calls
+`verify` at `.github/workflows/semantic-release.yml:130`.
+
+So the fix is one line — add `pack-install-run` to `verify` — and the rule is:
+
+> **A package's release gate must install the packed artifact in a clean
+> environment and execute it.** Not "the build passed," not "the types check" —
+> those both passed while every published version was unstartable.
+
+The right place is the existing `verify` script, so it runs in
+`semantic-release.yml` before publish and stays available locally. The same gap
+should be checked for `@pdpp/cli` and `@pdpp/mcp-server`, which have sibling
+`verify` scripts. Worth noting separately: `pnpm` workspace linking is what
+*hid* this, so any check that resolves through the workspace is structurally
+incapable of finding it. That is the same lesson as the sidecar note, one layer
+up the stack.
+
+## Cost, and what stays broken
+
+Hundreds of call sites cannot and should not be migrated. The measurement is
+what makes this affordable — the real work is small:
+
+1. **Close the vocabularies** (types only, no call-site changes). Highest
+   leverage, lowest risk. Turns existing drift into compile errors.
+2. **Wire `pack-install-run` into `verify`** for all three published packages.
+   One line each; closes incident 5 permanently.
+3. **Land the redaction change** and give connectors a place to declare reason
+   tokens. Already proven; needs the declaration plumbed from the manifest.
+4. **Populate `failure_reason`** in `run-history-writer.ts` for non-scheduler
+   runs. Needs coordination — another agent is in that file.
+5. **Add the conformance gate** for `String()` on caught values, starting from a
+   ~1-entry allowlist.
+6. **Fix the three measured defects** — `statement-content-fingerprint.ts:142`,
+   `gmail/index.ts:1418`, `as-grant-revoke.ts:157`.
+
+New code is forced onto the new path by step 5, which is the only step that has
+to be right the first time; the rest are additive.
+
+**What stays broken in the meantime:**
+
+- There is still no logger, so incident 3's "zero lines matching the run_id"
+  stays true even after `failure_reason` is populated. A structured logger with
+  correlation fields is a real piece of work and is not scoped here. The spine
+  is the closest existing thing and connectors cannot reach it.
+- `inferRecoveryAction`'s prose-sniffing fallback and
+  `connector-coverage-policy.ts`'s substring matching both stay. They are the
+  seams where the typed design degrades into a guess, and closing them means
+  deciding what happens when a connector supplies no hint at all.
+- The ~170 error classes keep their three discrimination styles and their
+  `statusCode`/`httpStatus`/`status` drift. The duck-typed `.code` convergence at
+  the HTTP boundary works well enough that a base-class migration is hard to
+  justify on today's evidence.
+- The two fail-closed-null sites are real but need their own rule; the invariant
+  in this note does not reach them.
+
+## Open questions
+
+- Where do connectors declare their reason vocabulary? The manifest is the
+  obvious home, and `reason-display-messages.ts` already keys on
+  `(connector_key, reason_code)` with an anti-parrot rule — but its
+  exhaustiveness is enforced only by an AST-scanning test, which is the same
+  open-vocabulary weakness described above.
+- Should `failure_reason` be a closed union rather than free text? There is
+  already an unexported closed union in `runtime/classify-runtime-failure.ts:14`
+  that never returns empty. Exporting it may be most of the answer.
+- Is a real PII boundary needed where `redactStderrTail` currently sits, given
+  it passes plain email addresses through today?
+- Do `@pdpp/cli` and `@pdpp/mcp-server` have the same unpublished-dependency
+  defect? Only `local-collector` was checked.
+
+## Provenance
+
+Written from five production failures on 2026-08-18. Incidents 1 and 2 fixed
+same-day in `457e23e93` and `1d8995b0f`. Scale numbers re-measured against
+`deploy/prod-plus-fixes-0817`; the catch classification is a 55-site sample
+across 55 files (12.5% of 439), so the two durable-degradation sites are
+verified end-to-end but any extrapolation from them should be treated as an
+order-of-magnitude hint, not a census. The redaction proof-of-concept and its
+six tests are working code, not a sketch.
+
+Related: `connector-sidecar-packaging-2026-08-17.md` (incident 5 is the same
+"verified where it was built, not where it runs" shape) and
+`summary-evidence-projection-controller-2026-08-18.md`, whose subject is the
+sweep that produced incident 2.
+
+---
+
+## Addendum: the wider class is failures nothing reports
+
+Added 2026-08-18 after the note was applied to code outside this repo.
+
+An engineer migrating this instance's Postgres read the draft and found the
+same defect in their own verification gate within five minutes:
+
+```bash
+tgt_rows=$(psql -Atqc "SELECT count(*) FROM ${tbl};" 2>/dev/null || echo "ERROR")
+```
+
+That is `[object Object]` in bash. The gate fails correctly and exits non-zero
+while collapsing permission denied, a missing table, a dropped connection, and
+genuine data loss into one string. On migration night that is the difference
+between a five-minute fix and a torn-down restore. It appeared twice, and the
+fix was the same: capture stderr and log it before failing.
+
+Worth recording because it says the rule is not TypeScript-specific and not
+about error objects. It is about any transform on the way out of a failure
+path that keeps the fact of failure and discards which failure.
+
+### The count that reframes it
+
+That engineer's session produced four significant findings, and only one was a
+thing breaking loudly:
+
+- Postgres crash-recovering behind `RestartCount: 0` and green healthchecks
+- meilisearch crash-looping behind a healthcheck that only probed its own port
+- promtail dying on a full disk without telling anyone
+- `pg_dump` exiting 0 while producing an unrestorable dump
+
+Four of five were *nothing reported it*, not *it broke*. Our five incidents
+were the narrower shape — something reported a failure and destroyed its cause.
+Both belong to one family, and the wider one is the more dangerous half,
+because the narrow shape at least leaves a row to investigate.
+
+So the invariant needs a second clause. The first is already stated above: a
+failure that crosses a durability boundary must carry a code, a human cause,
+and a PII-safe detail. The second: **a component whose failure is survivable
+must still be observable — a supervisor that restarts, a probe that recovers,
+or a process that degrades silently is not thereby healthy, and something must
+say so.** `RestartCount: 0` is the canonical false negative: the container
+never died, so every container-level signal stays green while the process
+inside it crashed and recovered.
+
+This is why the missing logger matters more than its size suggests. Nineteen
+`console.*` calls in the server and none carrying `run_id` is not merely
+inconvenient; it means the only detection layer for an in-process crash is the
+database's own log, which on this host was reaching no aggregator at all —
+promtail scrapes the systemd journal and has neither docker discovery nor
+socket permission. The blind spot was total, not partial, and nothing reported
+that either.
+
+### What this does not change
+
+The remediation scope stays three sites. The measurement in this note stands:
+439 catches, 97% benign, the `[object Object]` archetype with no surviving
+siblings. Adding a second clause to the invariant does not widen the migration
+— it widens what counts as evidence when deciding whether a component is
+healthy, which is a monitoring question, not a refactor.
+
+### A third variant: reported correctly, in a field nobody read
+
+The migration engineer, having just added the second variant, produced the
+third by making the mistake himself an hour later. He checked whether the
+maintenance sweep's backlog had drained:
+
+```sql
+SELECT record_snapshot_state, count(*) FROM connector_summary_evidence GROUP BY 1;
+-- current | 29
+```
+
+Twenty-nine of twenty-nine current, so he reported the backlog clean and
+warned that a post-deploy measurement could not distinguish the fix from the
+status quo. The real backlog at that moment was nine rows, and the sweep had
+logged seventy consecutive no-progress passes. `dirty` is a different column.
+
+Nothing was hidden, destroyed, or masked. The failure was fully and correctly
+recorded, in a field he did not read.
+
+This is the same error made earlier the same day from the other direction —
+reading `connector_summary_evidence` columns and reporting "15 of 21 green"
+while the Sources page showed otherwise. Both readers were competent, both
+queried real data, and both were confidently wrong.
+
+The structural cause is that this table carries seven signals — `dirty`,
+`state`, `record_snapshot_state`, `terminal_facts_state`,
+`manifest_declaration_state`, `retained_bytes_state`,
+`list_summary_projection_state` — none of which is the verdict, while the
+actual verdict lives in `isHealthyConditionSet`
+(`reference-implementation/runtime/connection-health.ts:1739`), ten conditions
+evaluated together. Any reader who samples one column gets a plausible answer
+that is not the answer.
+
+**A system with N independent health signals and no single authoritative one
+invites every reader to pick a different signal and be confidently wrong.**
+
+The remedy is not better logging — the logging was perfect. It is that a
+verdict must have exactly one source, and the raw signals must be hard to
+mistake for it. That is a naming and API problem: `record_snapshot_state` reads
+like the state of the record snapshot, which it is, and like the state of the
+row, which it is not.
+
+Worth noting what this shares with the other two variants and what it does
+not. All three end with an operator holding a wrong conclusion. Only the first
+involves anything being destroyed, and only the second involves anything being
+unreported. The third needs neither — it is sufficient to offer several true
+answers to slightly different questions and let the reader choose.

+# The fused source status line — why it wasn't there, and what it cost
+
+2026-08-22
+
+The owner asked on 2026-08-19 why the console has no product-standard fused
+status string — the "Last updated 3 hours ago / Syncing now" line every mature
+sync product shows — and asked for the underlying design problem explained
+rather than patched over. This is that explanation, and the design that shipped.
+
+## What the owner saw
+
+On `/sources`, each row showed one colored glyph (`●◐⊘○◌⏸`) and nothing else
+about state. The status *text* existed but was `sr-only` — announced to screen
+readers, invisible to eyes. Freshness never reached the row at all. Whether a
+source was syncing right now was used only to disable buttons and set a polling
+interval; it was never displayed.
+
+So the row could not answer any of the three questions an owner actually has:
+what is this source's state, when did it last update, and is it working right
+now?
+
+## Why this is not a one-line fix
+
+The tempting fix is to concatenate three fields. That fails because **these are
+three independent axes that routinely disagree**, and the disagreements are
+exactly the cases that matter:
+
+| Situation | Freshness | Activity | Verdict | What the owner needs to hear |
+|---|---|---|---|---|
+| Sync running against a broken connector | stale | syncing | blocked | **Blocked** — the run will not save it |
+| Healthy source mid-refresh | fresh | syncing | healthy | Working, syncing now |
+| Stale because every run fails | stale | idle | blocked | Blocked, and here is how long |
+| Paused with a stale in-flight run flag | stale | "syncing" | n/a | **Paused** — it is not syncing |
+| Never connected | none | idle | unknown | Never updated |
+
+A source can be fresh and failing. It can be stale and syncing. It can look busy
+and be dead. Any fused string has to *resolve* those conflicts, and the
+resolution rule is the entire design — not the concatenation.
+
+## What the code actually did: last-writer-wins
+
+`deriveRenderedSourceStatus` in `apps/console/src/app/(console)/lib/source-actionability.ts`
+resolves the conflict by returning early:
+
+```ts
+if (running) {
+  return { dot: "◌", freshnessNote: null, kind: "pending", label: "Syncing", tone: "muted" };
+}
+```
+
+An in-flight run **erased both the freshness note and the health verdict**. A
+source that was blocked, stale, and had a doomed retry in flight rendered as
+`"Syncing"` in a muted tone — the calmest thing on the page.
+
+That is the fabricated-green defect class this program exists to kill, in
+miniature. Nobody wrote "pretend it is fine"; the most reassuring axis just
+happened to be evaluated last and win the single available slot. **Fabricated
+green is usually an architecture accident, not a lie somebody typed.** One slot
+plus three axes forces a silent choice about which truth to discard, and the
+convenient one wins by default.
+
+## The rule that shipped
+
+> **Activity is additive, never substitutive.**
+
+"Syncing" is something a source is *doing*, not something it *is*. So:
+
+- The **state slot** always holds the worst honest verdict.
+- **Freshness** gets its own slot and is never erased by activity.
+- **Syncing** is appended as a separate clause and owns no color of its own.
+
+The line therefore reads `Blocked · Last refreshed 6 days ago · Syncing now` —
+which is uncomfortable, and correct. The old rendering of that same source was
+the single word `Syncing`.
+
+Implementation: `apps/console/src/app/(console)/lib/fused-source-status.ts`.
+Axes are ranked worst-to-best (`SEVERITY_BY_KIND`) and the worst wins the slot
+by comparison, not by branch order — so adding a state later cannot silently
+reintroduce last-writer-wins.
+
+### Recovering the discarded verdict
+
+Because `deriveRenderedSourceStatus` throws the verdict away on `running`, the
+fused line needs it back. `deriveSourceVerdictStatus` re-derives the
+verdict-only status, and `projectSourceActionability` passes it as
+`verdictFallback` — but **only for the `running` collapse**. `revoked`,
+`paused`, and `pending` are lifecycle facts that outrank any verdict: a revoked
+source is revoked no matter how its last verdict read. Passing the fallback for
+those would let a stale "Blocked" overwrite "Revoked".
+
+### Honest absence
+
+A missing freshness note is not "fine". When a source has never had a
+successful run, the line says `Never updated` rather than omitting the slot —
+omission reads as "not applicable", which is a stronger claim than the evidence
+supports. When a source *has* succeeded but carries no annotation, the slot is
+genuinely absent rather than guessed.
+
+The server already folds activity into its own freshness annotation
+(`rendered-verdict.ts` emits `"Refreshing now."` when `badges.syncing`). That
+phrasing is dropped here and re-added from the real activity flag, so the
+activity slot has exactly one owner and cannot double up.
+
+## What is guarded
+
+`fused-source-status.test.ts` pins the disagreement cases, and the rule is
+mutation-proven three ways: restoring last-writer-wins, inverting the severity
+comparison, and letting paused/revoked show as syncing each fail tests that name
+the specific dishonesty.
+
+CSS state rules change **color only** — the geometry-bearing rules are
+state-independent — so the list never reflows as sources change health. This is
+enforced by the pre-existing "status state does not create separate row
+geometry" invariant.
+
+## Coordination note
+
+This work deliberately does **not** restructure
+`apps/console/src/app/(console)/lib/connection-evidence.ts`, which the
+`labels-naming-0822` lane is changing. The fused line *composes* the label
+strings that module and the server verdict produce; it defines no owner-facing
+label vocabulary of its own beyond the two connective strings `"Syncing now"`
+and `"Never updated"`. If that lane renames a pill label, the fused line picks
+it up with no change here.
+
+## What is not addressed
+
+- Freshness granularity is still the server's day-level prose
+  (`"3 days ago"`), not minute-level. Mixing the client's `formatRelative`
+  (minutes/hours) with the server's day buckets would read inconsistently, so
+  one source of truth was kept. A finer server annotation would improve this.
+- The detail page still renders the axes separately. Only the `/sources` list
+  row is fused so far.

+# Graceful drain on SIGTERM: do not re-attempt
+
+**Verdict: rejected, with production evidence. `fix/graceful-drain-0821` should
+not be landed.**
+
+This note exists because the idea is genuinely appealing and has already been
+built twice. Without a durable record it will be rediscovered — the reasoning
+below is what stops the third attempt.
+
+## What was tried
+
+`fix/graceful-drain-0821` (uncommitted work in
+`~/.tmp/graceful-drain-0821`) makes `drainActiveRuns` CANCEL every in-flight
+run on SIGTERM and then await its terminalization within a 5s budget, so the
+dying process writes each run's own terminal event instead of leaving it to be
+adjudicated at the next boot. It also closes run admission during shutdown and
+adds a `shutdown_drained` terminal reason.
+
+The engineering is careful and the diagnosis of the read-side problem is right
+(a restart-ended run should not be reported as `run.failed`). The mechanism is
+what does not work.
+
+## Why it does not work
+
+**The budget cannot cover the work.** Production sets no `--stop-timeout`, so
+Docker's 10s default governs, and `--stop-timeout` is fixed at container
+creation — Docker has no equivalent of systemd's runtime `EXTEND_TIMEOUT_USEC=`.
+Real runs take minutes: production medians span 9s (github) to 1221s (ynab). The
+gap is two orders of magnitude and is not closable by tuning.
+
+**It was measured failing exactly that way.** A production shutdown logged:
+
+```
+drained:0, elapsedMs:5000, timedOut:1
+```
+
+The drain spent its entire budget and abandoned the run anyway, having consumed
+half the window before SIGKILL while making the failure look handled. That is a
+negative win — worse than not trying, because it delays the storage close that
+still has to happen.
+
+**Correctness never depended on it, and cannot.** A `kill -9`, an OOM kill, or a
+power loss gets no drain at all. Any design that needs the dying process to
+write its own terminal state has an unhandled case by construction. The
+successor must adjudicate regardless, so the drain is a redundant second
+mechanism guarding a case the first already covers.
+
+This is the standard layering, not a local shortcut: Temporal's
+`WorkerStopTimeout` defaults to 0s and the service writes the terminal state on
+a timer; Kafka recovers a dead producer's transaction through the successor's
+`InitProducerId` epoch bump.
+
+## What replaced it
+
+`2ddcca1b8` ("perf(shutdown): drop the connector drain from the SIGTERM path")
+removed the shutdown call site and left `drainActiveRuns` on the controller,
+where it means "await in-flight runs" for the watchdog, `awaitRun`, and the test
+suite. Correctness lives in `reconcileOrphanedRunsAtBoot`
+(`lib/controller-boot.ts`), which writes `run.abandoned` for any run whose owner
+epoch is not the current one.
+
+That commit is an ancestor of the current base. **The drain branch predates it
+and does not contain it**, so landing the branch would re-introduce a mechanism
+this repo already removed on evidence.
+
+## The valid insight, and where it went instead
+
+The drain branch was right that a restart-ended run must not be reported as a
+connector failure. That belongs on the read side, where it works for every
+restart shape including `kill -9`:
+
+- `8609f37a8` — restart-abandoned runs no longer classify connection health;
+  they defer to the last run that actually observed something.
+- `3cf21fd04` — restart-ended runs no longer reset the schedule anchor, so a
+  restart stops delaying the next run by a full interval.
+
+Both apply regardless of how the process died, which is precisely the property
+the drain could not offer.
+
+## If someone still wants a drain
+
+The only version worth discussing would need all of: a stop timeout raised well
+beyond 10s at container creation, evidence that the raised timeout does not get
+the process SIGKILLed mid-storage-close, and a reason why successor
+adjudication is insufficient despite handling the `kill -9` case the drain
+cannot. Absent all three, this is settled.

+# Local-collector coverage: two parallel systems, not one dropped field
+
+Investigation of PR #166 owner-feedback item C1: four local-collector sources
+(peregrine Claude Code, peregrine Codex, Simon VM Claude Code, vivid fish Claude
+Code) emit coverage facts with blank `covered`/`considered` while server-run
+connectors emit real numbers.
+
+**Read this before "fixing" the blank denominators.** The obvious fix is wrong
+and would fabricate a false coverage claim. The disproof is in §3.
+
+## Verdict
+
+The owner's reasoning — "local collector runs a connector the same way the
+server does, so denominators should depend on the CONNECTOR, not the runner" —
+is sound in principle but does not describe how this is built. There is no
+single runner with a dropped field. There are **two parallel coverage systems**
+with different units, vocabularies, and transports.
+
+This is a **per-connector gap plus a transport that cannot carry counts**, not a
+runtime silently discarding numbers the connector emitted. `claude_code` and
+`codex` emit no `DETAIL_COVERAGE` message at all — zero occurrences in either
+`connectors/*/index.ts`.
+
+| | Server path | Local path |
+|---|---|---|
+| Signal | `DETAIL_COVERAGE` message | `coverage_diagnostics` records |
+| Unit | per-record counts | per-**store** status enum |
+| Vocabulary | `covered` / `considered` | `collected`, `inventory_only`, `missing`, `deferred`, `excluded`, `unsupported`, `unaccounted` |
+| Verdict source | `covered` vs `considered` | `localCoverageConditionForStatus` |
+
+## 1. Three independent barriers
+
+Any one of these alone is sufficient to produce blank denominators. All three
+are present, so a partial fix changes nothing.
+
+**Barrier 1 — the producer has no numeric field.**
+`packages/polyfill-connectors/src/local-source-inventory.ts:168-181`.
+`CoverageRecord` carries `status`, `store`, `stream`, `reason` — no count.
+`coverageStatus()` (:541) answers "does this store exist and what is its
+policy", one status per store. Counts that *are* measured get stringified into
+prose at :245:
+
+```ts
+return `enumeration complete, ${input.examined} examined (${input.emitted} emitted)`;
+```
+
+**Barrier 2 — the wire contract forbids counts.**
+`packages/reference-contract/src/reference/index.ts:1839-1848`:
+
+```ts
+const DeviceTerminalRunFactSchema = {
+  additionalProperties: false,
+  properties: {
+    coverage_statuses: { items: { minLength: 1, type: "string" }, minItems: 1, type: "array" },
+    scoped: { type: "boolean" },
+    stream: { minLength: 1, type: "string" },
+  },
+  required: ["coverage_statuses", "stream"],
+```
+
+`additionalProperties: false` — numeric coverage is actively rejected, not
+merely absent. `canonicalTerminalRunCommitEnvelope`
+(`packages/reference-contract/src/common/terminal-run-commit.ts:32-45`)
+reconstructs each fact from exactly these three fields, so anything else is
+dropped before signing.
+
+**Barrier 3 — the server hard-codes null.**
+`reference-implementation/operations/local-device-terminal-collection.ts:249-258`:
+
+```ts
+const fact = readRuntimeCollectionFact({
+  checkpoint: "committed",
+  collected: 0,
+  considered: null,
+  coverage_statuses: coverageStatuses,
+  covered: null,
+  ...
+```
+
+This exactly reproduces the observed rows: `covered: null`, `considered: null`,
+`collected: 0`, `checkpoint: "committed"`.
+
+## 2. The local path is NOT verdict-less
+
+Worth stating because "coverage unknown" was over-scoped in the ledger. The
+server has a working local coverage authority:
+`reference-implementation/server/ref-control.ts:3829-3848` maps
+`collected -> "complete"`, `inventory_only -> "inventory_only"`,
+`unaccounted -> "gaps"`. `coverageTone` (`runtime/rendered-verdict.ts:560`)
+renders `complete`, `deferred`, and `inventory_only` all **green**.
+
+`connector-coverage-policy.ts:246-249` treats `observed_collected` (derived from
+`coverage_statuses`) as legitimate non-numeric coverage proof, and
+`verdict.proven` can return `"complete"` with no denominator at all.
+
+So blank denominators do not automatically mean a red or unknown stream. Check
+the rendered verdict per stream before scoping work.
+
+## 3. Why `examined` is NOT the denominator (the trap)
+
+The prose already contains real numbers, so piping them into `considered` looks
+like a one-line fix. It is a fabricated denominator. Production disproof
+(peregrine Codex, `cin_ece4bfe5096b8bf67a1468c2`):
+
+```
+coverage_diagnostics reason: "enumeration complete, 566589 examined (0 emitted)"
+actual stored records:       758,345
+```
+
+**Examined (566,589) is LOWER than stored (758,345).** `scanLocalJsonl`
+(`packages/polyfill-connectors/src/local-jsonl-cursor.ts:139-172`) is
+incremental: on a `fast_skip` or `append` decision `onLine` fires only for new
+bytes. `examined` is therefore a **per-run delta**, not a corpus size.
+
+Rendering that as `considered` would show "566589 of 566589 — complete" for a
+run that skipped most of the corpus. That is precisely the fabricated-watermark
+defect class this program exists to eliminate.
+
+It is also not uniform. `sessions` reports `"declared rollout source"` — **no
+count exists at all**. Any fix must be per-stream.
+
+## 4. What an honest denominator would be
+
+For these inventory-style local collectors: **corpus discovered vs corpus
+parsed**, measured at the enumeration site independently of the incremental
+cursor — e.g. sessions/transcript files discovered on disk vs successfully
+parsed. That satisfies the standard `DetailCoverageParams` already documents
+(`connector-runtime.ts:494-509`): measured at the enumeration site, never
+aliased to the collected/emitted count.
+
+Today's counters cannot supply it. `messagesExamined`
+(`connectors/claude_code/index.ts:1447-1470`) is honestly measured per-line and
+classified independently of emission — it is a *good* number, just a
+per-run-delta one. Getting a real denominator means teaching the connectors to
+measure corpus size on a full pass, separate from the cursor.
+
+Streams that genuinely cannot have one (a store whose whole content is
+`inventory_only` by policy) should keep saying so precisely via
+`coverage_statuses` rather than reporting a blank number.
+
+## 5. Cross-repo scope
+
+The end-to-end fix spans three places, one of which is not this repo:
+
+- **data-connect** (`PDP-Connect/data-connect @ 9155e57`) — the collector
+  runtime and `@pdpp/connector-protocol` that build `terminal_facts`. Vendored
+  here as `vendor/pdpp-collector-runtime-0.0.1.tgz` and
+  `vendor/pdpp-connector-protocol-0.0.1.tgz`; not editable in this repo.
+- **this repo, reference-contract** — the wire schema AND
+  `canonicalTerminalRunCommitEnvelope`, which is the **commit-id / replay hash
+  authority**. Widening the fact shape changes envelope hashes, so it is a
+  compatibility break requiring a versioned migration, not an additive field.
+- **this repo, reference-implementation** — `normalizeTerminalFacts` and the
+  coverage policy.
+
+Recorded as a known architectural gap. Not attempted here: a hash-contract break
+across repos needs deliberate scoping.
+
+## 6. Related finding: freshness is a separate defect
+
+Ledger C3 suspects local sources write no run history. **They do** — 537
+succeeded runs for peregrine Claude Code, 380 for peregrine Codex, all recent.
+C3 is right only for Signal.
+
+Local-device runs are deliberately discarded for health
+(`ref-control.ts:5215-5221`, `localDeviceBacked ? null : ...`), so freshness
+rests entirely on the heartbeat gate. A single dead-lettered row out of 10,001
+forced `blocked` -> `stalled` -> no freshness proof -> RED "can't collect" on a
+2.5-million-record source whose collector was healthy. Fixed separately in
+`localDeviceFreshnessHeartbeatAt`; see
+`test/local-device-terminal-backlog-freshness.test.ts`.

+# A finished import has no way to prove what it ingested
+
+**Status:** superseded 2026-08-20. The premise below was wrong on the facts, and
+the proposed build is unnecessary. See "What was actually true" at the end.
+Written 2026-08-19 after a related fix was deliberately scoped to exclude this
+case.
+
+## The state that has no honest verdict
+
+Two sources on this instance hold real data and can never be green:
+
+- Google Maps Timeline Import — 299,248 records
+- WhatsApp — 120,042 records
+
+Both are `source_kind='manual'`, paused, with zero runs ever and zero rows in
+`connector_detail_gaps`, `run_history`, or `acquisition_batches`. They are
+finished one-time file imports. Nothing will run again.
+
+`isHealthyConditionSet` requires `SourceCoverageComplete` to be true. Coverage
+evidence is produced by a collection run. No run, no evidence, no green — on a
+source holding 419k records the owner can read today. The page says "Not
+measured", which he reads as broken.
+
+## Why this is not the same as the case next to it
+
+An adjacent problem looks identical from the pill and is not. Gmail has 32
+terminal gaps, each carrying `observed_size_bytes > configured_limit_bytes` —
+a specific attachment, a recorded size, a recorded cap. Gmail measured its
+shortfall and can enumerate it. That case is being handled by
+`unfillableAccounted`, a flag whose contract requires **every** outstanding gap
+to carry durable per-item evidence.
+
+These two imports fail that contract on the facts. There is no `terminal_gap`
+axis to account for, because there are no gaps. Their coverage axis is
+`unknown` — never measured — not `terminal_gap` — measured and partly
+impossible.
+
+**"Measured, and this part is provably impossible" and "never measured, and
+never will be" are different states and must not share a signal.** Setting the
+Gmail flag for an import would assert that every outstanding gap is proven
+unfillable over an empty set, inferred from the total absence of evidence.
+That is the exact false-green the anti-green tests exist to catch.
+
+An earlier framing in this work treated both as one design. That was wrong, and
+the evidence above is what corrected it.
+
+## The line that already exists, and holds
+
+`Fresh` can be satisfied by `not_applicable` (`conditionIsSettledSatisfied`).
+`SourceCoverageComplete` cannot — it is gated by `conditionIsTrue`
+(`connection-health.ts:1830`). That asymmetry is deliberate, and
+`source-state-truth-2026-08-18.md` states why: a completed import buys
+exemption from a *freshness* proof, never from proving it ingested what it
+claimed. Relaxing coverage would let any source with no evidence read as
+complete.
+
+So the fix is not to exempt coverage. It is to let an import **prove** its
+coverage.
+
+## The shape a proof would take
+
+`connector-coverage-policy.ts` already declares a `snapshot_import_receipt`
+coverage strategy alongside `checkpoint_window` and `full_inventory`. No
+connector emits evidence for it. The placeholder is the design, unbuilt.
+
+What it needs, roughly:
+
+1. The manual-upload route writes an `acquisition_batches` receipt at import
+   time recording what the file claimed to contain and what was ingested. The
+   table exists and is empty for both connections.
+2. The stream's manifest declares `coverage_strategy: snapshot_import_receipt`.
+3. The coverage projection grows a branch that reads that receipt as proof, the
+   way it reads a run's coverage report today.
+
+Then a finished import satisfies coverage the same way a collecting source
+does — by evidence, not by exemption — and the terminal label already built for
+it (`Fresh: not_applicable`, "Import complete") becomes reachable.
+
+## Cost and scope
+
+This touches the manifest schema, the upload route, and the coverage read path.
+It is a separate change from the Gmail work deliberately: bundling them would be
+two problems in one story, and the Gmail fix is narrow and provable on its own.
+
+Worth stating plainly: until this exists, these two sources stay honestly red.
+That is the correct outcome. The alternative — green by exemption — would mean
+the page can no longer distinguish a source that proved its completeness from
+one that never tried.
+
+## Open questions
+
+- Does the receipt record the file's own claim (a manifest inside the export,
+  a row count) or only what PDPP ingested? A receipt that only records what was
+  ingested proves nothing about what was missed.
+- Are existing imports retrofittable, or is this only correct for imports made
+  after it ships? Both sources here predate any receipt, so they may need a
+  one-time backfill with explicitly weaker provenance — and that weaker
+  provenance should be visible, not silently equal to a real receipt.
+- Does a partial import (an interrupted upload) produce a receipt that honestly
+  reports incompleteness, or none at all?
+
+---
+
+## What was actually true (2026-08-20)
+
+Three of the four load-bearing claims above are false. Steps 1-3 should not be
+built.
+
+**"No connector emits evidence for `snapshot_import_receipt`" — false.** Both
+connectors already emit an artifact-grounded coverage declaration, and both
+manifests already declare the strategy (`google_maps.json:166,246`,
+`whatsapp.json:140,208`). `google_maps` counts every point/segment element the
+parser produced, at the parse site, and reports `covered < considered` when an
+element had no usable id or timestamp (`finishPoints`/`finishSegments`,
+hardened by `e1b92b36c` the same week this note was written). `whatsapp` counts
+the archive's own file and attachment listing and subtracts media the bounded-
+read policy dropped. Neither denominator is recomputed from the survivors.
+
+**"Nothing will run again" — false, and this is the load-bearing one.** The
+uploaded artifact is durable and is re-read on **every** run, not just at setup:
+`ManualUploadDurableSourceBinding` carries `import_dir`/`import_dir_env_var`
+specifically so they survive promotion, and the run orchestrator injects the
+directory as the connector-declared env var. These connections are re-runnable
+against the file already on disk.
+
+**"Coverage evidence is produced by a collection run" — true, and sufficient.**
+`connector_summary_evidence` is keyed by `connector_instance_id`, but is only
+ever populated by folding a terminal run event's `collection_facts`. Zero runs
+therefore means `stream_latest_facts_json IS NULL` and axis `unknown` — which is
+the correct and honest reading of "never measured", not a defect.
+
+Derivation over the exact shapes these two connectors emit, through the real
+`deriveStreamCoverageCondition`:
+
+| fact | axis |
+| --- | --- |
+| `considered=299248, covered=299248` (fully reconciled) | `complete` |
+| `considered=299248, covered=299243` (5 elements unaccounted) | `partial` |
+| whatsapp attachments, media dropped by read policy | `partial` |
+| no run ever — the live state today | `unknown` |
+
+So the proof path is built and works end-to-end, including the honest partial.
+**The remedy is operational — re-run each connection once against its stored
+artifact — not a receipt, a manifest change, or a read-side branch.** A backfill
+would be strictly worse: it would synthesize a denominator from records already
+ingested, which is the fabricated-denominator anti-pattern (`covered ==
+considered` recomputed from survivors) that the coherence contract exists to
+reject, and it could never produce the `partial` verdict a real re-run can.
+
+One genuine defect did come out of this review, fixed separately: `CredentialsValid`
+had no branch for a connector that authenticates to nothing, so both sources sat
+at `credentials_not_probed`/`unknown` forever. That is now `not_applicable`,
+derived from the manifest declaration.
+
+What remains unprovable either way, and is worth not overclaiming: a reconciled
+artifact proves the run ingested everything the *file* contained. It says
+nothing about whether the file is a complete export of the owner's history —
+the provider decides what goes into it, and no check on this side can see past
+that.

+# Semantically Bounded Consent (derived streams vs dynamic selectors)
+
+Status: captured
+Owner: Tim
+Created: 2026-08-07
+Related: spec-core Grant semantics; derived subset streams aside (non-normative);
+spec-deferred predicate scoping; openspec change harden-pdpp-authorization-and-0-1-migration
+(critical-extension and seam-spike gates); inbox/8-7-26-chatgpt-convo.txt
+
+## Question
+
+A user wants consent bounded by a subjective rule ("my accountant may read financial
+documents, excluding items my agent flags as private"). Can PDPP express this without
+changing the grant model or sync semantics, and what minimal seams should exist so a
+future extension can carry it?
+
+## Context
+
+Two designs were compared, independently by two analyses (this repo, 2026-08-05; an
+external ChatGPT session with its own red-team, 2026-08-07), converging on the same
+answer.
+
+Dynamic selectors: grants carry typed, monotonically narrowing constraints evaluated
+per request, possibly by a model. Rejected for Core: it converts the immutable grant
+from the complete authorization into a maximum bound, leaks excluded records through
+side surfaces (counts, aggregations, search, expansion), risks per-grant membership
+state at platform scale, and produces interoperability in name only when evaluator
+contracts differ.
+
+Derived streams: an evaluator materializes a subset stream upstream; the recipient
+receives an ordinary deterministic grant to that stream. Core is untouched, side
+surfaces are contained because excluded records are absent from the granted stream,
+and existing mutable-stream sync carries membership changes.
+
+Honest limit of the derived-stream design: the grant fully describes authorization
+only syntactically. Stream membership changes at the evaluator's discretion, so the
+indeterminism moves behind the stream name rather than disappearing. The real
+arguments are Core stability, side-channel containment, and reuse of existing sync.
+
+Evaluator placement is a deployment property, and the spec stays deployment-agnostic.
+Where the evaluator is co-located with the data (a personal server, or the provider
+itself), no second disclosure occurs. A remote evaluator is a second grantee and needs
+its own grant. An extension should state this trust consequence explicitly.
+
+## Stakes
+
+Low until an implementer wants it. The protocol-design payoff is flexibility: the same
+seams cover role changes, household membership, classification, and jurisdiction, well
+beyond AI evaluators.
+
+## Current Leaning
+
+1. Prototype subjective consent as a materialized derived stream. No Core change.
+2. One near-term semantic clarification worth owner review before or after the v0.1.0
+   freeze: on subset streams, a tombstone signals membership removal and does not
+   assert source deletion. This ambiguity exists today without any evaluator, and the
+   two claims carry different recipient obligations. One sentence, optionally a reason
+   field later.
+3. Reserve a namespaced critical-extension mechanism (an enforceable constraint an RS
+   must reject when unrecognized, distinct from ignorable capabilities). PR #77's
+   accepted proposal already moves in this direction; keep the reservation, publish no
+   selector grammar.
+4. Revisit a Dynamic Disclosure Profile only after derived streams fail against
+   several real use cases, and require: hard Core boundary, evaluator identity,
+   decisions tied to record versions, fail-closed behavior, and authoritative
+   resynchronization rules.
+
+## Promotion Trigger
+
+A second implementer asks for subjective or externally evaluated consent, or derived
+streams demonstrably fail a real deployment (per-recipient stream explosion, consent
+legibility complaints, or re-consent churn on stream redefinition).
+
+## Decision Log
+
+- 2026-08-07 — Captured from convergent internal (2026-08-05) and external analyses.
+  Owner direction: keep the protocol flexible and cohesive; no build planned; the
+  tombstone clarification is the only near-term action candidate.

+# What a source's state should tell its owner
+
+**Status:** intake. Terminal model proposed, not owner-ratified. One case
+implemented as proof; the rest is unbuilt.
+**Date:** 2026-08-18
+
+## The evidence
+
+The owner's goal is every source green, honestly — green only if genuinely
+collecting, never by loosening a condition. Today `/sources` shows 23 sources in
+five display states, and four of the five lie in a way the owner can catch:
+
+| shown | reality |
+|---|---|
+| `○ Not measured · Fresh today` | claude-code holds 2,408,082 records and is collecting right now |
+| `○ Not measured · Freshness has not been measured yet` | Google Maps Timeline Import holds 299,248 records; the import finished and will never run again |
+| `◐ Needs refresh · Review: Resume schedule` | Chase is fine; an operator disabled its schedule to stop an OTP loop |
+| `⊘ Can't collect` + `Last successful refresh today` + 2,129 records | USAA, all three simultaneously true |
+
+Verified in production today:
+
+```
+claude-code  local_device  2408082  stale     (3 instances: 2.4M, 38k, 20k)
+codex        local_device  1299535  fresh
+google-maps  manual         299248  fresh
+whatsapp     manual         120042  fresh
+usaa         account          2129  fresh
+```
+
+Both `manual` sources have **zero rows in `run_history` and zero schedules**.
+There is nothing to run, and nothing that will ever run.
+
+The four failures have one shape. `isHealthyConditionSet`
+(`reference-implementation/runtime/connection-health.ts:1755`) collapses ten
+conditions to one boolean, and it requires three of them to be affirmatively
+`true`:
+
+```
+CollectionSucceeded === true
+SourceCoverageComplete === true
+Fresh === true
+```
+
+Three of those ten are also required *not* to be `false`, and `BacklogClear`
+must not be `error`. The predicate has exactly one caller, `classifyHealthy`,
+the last of fourteen ordered classification steps.
+
+The collapse is not the bug by itself. The bug is that the predicate cannot
+distinguish **"we don't know"** from **"the question doesn't apply here"**, so
+it treats both as not-green. A finished import can never produce a freshness
+proof, so it can never be green, no matter what the owner does.
+
+## What the code already knows
+
+This codebase already diagnosed this problem and solved it one layer too high.
+`ConnectionConditionStatus` (`connection-health.ts:107`) has four values, and
+the doc comment on the fourth is worth quoting:
+
+> `not_applicable` : the condition cannot apply to this connection at all,
+> because the evidence source it reads does not exist here. This is a *settled*
+> answer, not a pending one.
+>
+> `not_applicable` exists so the projection stops encoding certainty as doubt.
+
+And then, three lines later:
+
+> Classification treats `not_applicable` exactly as it treated the `unknown` it
+> replaces: it is never `true` and never `false`, so no headline state, axis, or
+> healthy-set predicate changes. **Only presentation changes.**
+
+That last sentence is the decision to revisit. The concept is right and already
+shipped; it was deliberately confined to cosmetics. Making it load-bearing in
+the healthy predicate is a smaller change than inventing anything new.
+
+Two more pieces already exist:
+
+- **`source_kind`** is a real column with a CHECK constraint over `account`,
+  `local_device`, `browser_collector`, `manual`
+  (`server/postgres-storage.ts:885`). The two "never measured" sources are
+  exactly the two rows with `source_kind = 'manual'`. The manifest already
+  carries enough to decide this — nothing new needs to be declared.
+- **`COVERAGE_UNKNOWN_STALE_COLLECTOR`** (`connection-health.ts:2716`) already
+  says *"This local collector build predates coverage evidence the server now
+  requires. Update the collector."* That is the honest sentence for the 2.4M-record
+  case. It exists, it is correct, and the sources list does not show it.
+
+## The dimensions, derived from the incidents
+
+Not a taxonomy invented for symmetry — each of these is a distinct axis because
+a real source varies on it independently of the others.
+
+1. **Is data arriving?** claude-code: yes, 2.4M records. Independent of whether
+   we can prove anything about it.
+2. **Is coverage provable?** Separate from (1). The stale collector emits data
+   but not the stores that prove coverage. Data flowing and proof complete are
+   genuinely orthogonal — that pair is the whole "Not measured · Fresh today"
+   contradiction.
+3. **Is currency meaningful, and if so, is it current?** Two questions, and the
+   model only asks the second. For a finished import the first answer is *no*,
+   which makes the second a category error.
+4. **Who can resolve the blocker?** Connector maintainer, owner, operator, or
+   external provider. USAA's detail page says "Connector code needs a fix"; the
+   list says "Can't collect". The useful sentence is the one not shown.
+5. **Is this source finished by design?** No state expresses it. There is no
+   terminal state at all.
+
+## Is a single green/not-green verdict the right shape?
+
+**Yes — keep the boolean, and fix which conditions are required versus
+inapplicable per source.** I considered the alternatives seriously.
+
+**Two-axis (data-flowing × proof-complete)** describes the claude-code case
+exactly, and it is the model I most wanted to adopt. I rejected it because it
+does not generalize: it has nothing to say about the operator-paused case or
+the provider-down case, so those would need a third and fourth axis, and the
+owner would be reading a vector. The owner's stated goal is *every source
+green*. A goal phrased as a scalar needs a scalar answer.
+
+**A state machine with a terminal Archived/Complete state** is the wrong
+primitive because completeness is not a state a source *transitions* into
+through the health pipeline — it is a property of the source's kind, known at
+creation. Google Maps Timeline Import was complete the moment its import
+finished. Modeling it as a reachable state implies a transition that never
+fires, and this codebase has already been bitten by exactly that: the
+`terminal_facts_historical` exclusion in
+`summary-evidence-projection-controller-2026-08-18.md` stranded three
+production rows behind an exit condition that was unreachable by construction.
+
+**Keeping the boolean, fixing the required set** wins because the boolean was
+never actually the problem. The problem is that "required" is currently a fixed
+list of ten conditions applied uniformly to every source, when some conditions
+are unanswerable for some source kinds. Green should mean *every condition that
+applies to this source is satisfied* — which is what the owner already thinks it
+means.
+
+**What it costs.** The predicate stops being a fixed list, so reading it no
+longer tells you the whole rule; you must also know which conditions the source
+kind marks inapplicable. That is real complexity and I am not going to pretend
+otherwise. The mitigation is that inapplicability is derived from `source_kind`
+and the manifest — both durable, both already there — rather than from
+per-source configuration an operator can get wrong. The failure mode to guard
+is a condition marked inapplicable when it is merely unproven, which would
+manufacture exactly the false green the owner refuses to accept. Hence the rule
+below.
+
+### The rule
+
+> A source is green when every condition that **applies** to it is satisfied.
+> `not_applicable` is satisfaction. `unknown` is not.
+>
+> A condition may be marked `not_applicable` only from durable evidence that the
+> question is meaningless for this source — never from the absence of an answer.
+
+The second sentence is the entire safety property. "We couldn't measure it" and
+"there is nothing to measure" must never collapse, or this design becomes the
+loosening the owner rejected.
+
+## The manual-import case
+
+**Settled: `Fresh` is `not_applicable`, not `false` and not `unknown`, for a
+source whose acquisition is complete.**
+
+Not `true`. Claiming a finished 2023 WhatsApp export is "fresh" replaces one lie
+with another. The honest statement is that freshness does not apply.
+
+Coverage is deliberately **not** relaxed. A completed import must still prove it
+ingested what it claimed. Unknown or gapped coverage keeps it out of green — the
+completeness declaration buys exemption from a freshness proof only.
+
+`source_kind = 'manual'` already carries this and is written at exactly one
+place (`server/routes/ref-manual-upload-draft-connection.ts:687`). The health
+input takes a new `acquisition: { complete: true }` evidence field rather than
+reading `source_kind` directly, matching how every other signal reaches
+`computeConnectionHealth` — the projection trusts caller-supplied evidence and
+never reads storage itself.
+
+## The operator-paused case
+
+**Settled: this is already correct in the health model and wrong only in the
+rendering. Do not touch the health model.**
+
+`classifyOwnerPaused` (`connection-health.ts:1356`) runs third of fourteen
+steps, before every failure classifier, and routes a disabled schedule to
+`idle` — not `degraded`, not `blocked`. `isDegradingCondition` explicitly
+excludes `ScheduleEligible`. The model already says an operator pause is not a
+source defect.
+
+The damage is done downstream: `idle` + disposition `owner_refresh_due` renders
+the amber pill `"Needs refresh"` (`runtime/rendered-verdict.ts:432`), and the
+console prefixes the CTA with a hardcoded `"Review: "`
+(`apps/console/.../sources/sources-view.tsx:338`). Amber plus "Review" reads as a
+defect for a source that has none.
+
+The fix belongs in the pill vocabulary — an operator-paused source is not amber
+— and I am explicitly not making it here, because `rendered-verdict.ts` is the
+same file the actor vocabulary below would rewrite, and both should land
+together.
+
+## The actor vocabulary
+
+"Can't collect" names no actor, so it cannot be acted on. Every state must name
+who resolves it. All five derive from evidence that already exists:
+
+| state | meaning | derived from |
+|---|---|---|
+| **Collecting** | green | the healthy predicate above |
+| **Complete** | finished by design, final | `acquisition.complete` (from `source_kind = 'manual'`) |
+| **Needs your login** | owner action | `CredentialsValid` false, `CREDENTIAL_REQUIRED` / `CREDENTIAL_REJECTED` |
+| **Needs a collector upgrade** | owner action, distinct from the above | `COVERAGE_UNKNOWN_STALE_COLLECTOR` — exists today, unshown |
+| **Needs a connector fix** | maintainer action, not the owner's | `terminalCoverageCta`, `audience: "maintainer"` |
+| **Paused by operator** | operator action, not a defect | `SCHEDULE_PAUSED` |
+| **Provider is down** | nobody's action; wait | `REMOTE_SURFACE_FAILED`, `EXTERNAL_TOOL_UNAVAILABLE` |
+
+Every row maps to a reason code already in `CONNECTION_CONDITION_REASONS`. This
+is a presentation vocabulary over existing evidence, not new derivation — which
+is why it is cheap, and why it is worth doing before anything more ambitious.
+
+Note "Needs a collector upgrade" is the sentence the owner most needs today: it
+covers 2.4M + 1.3M + 38k + 20k records currently labelled "Not measured", and
+the string already exists in the codebase.
+
+## Proof of concept
+
+The manual-import case, implemented end to end in
+`reference-implementation/runtime/connection-health.ts`. It is the cleanest test
+of the model because it is the case with no possible workaround — no owner
+action can ever make a finished import fresh.
+
+New test: `reference-implementation/test/connection-health-completed-import.test.ts`.
+
+**Fail before** (against unmodified `connection-health.ts`) — this reproduces
+the production symptom exactly:
+
+```
+✖ a completed one-time import reports Fresh as not_applicable, not unknown
+  + actual 'unknown'  - expected 'not_applicable'
+✖ a completed one-time import is healthy without a Fresh=true proof
+  'idle' !== 'healthy'
+```
+
+**Pass after** — 6/6:
+
+```
+✔ a completed one-time import reports Fresh as not_applicable, not unknown
+✔ a completed one-time import is healthy without a Fresh=true proof
+✔ a completed import still needs complete coverage to be healthy
+✔ a completed import with a terminal coverage gap is not healthy
+✔ acquisition completeness does not leak into recurring sources
+✔ a recurring source that is genuinely stale is never rescued by this path
+```
+
+The last three tests are the ones that matter. They prove the change cannot
+manufacture a false green: coverage is still required, and a recurring source
+without the completeness declaration behaves exactly as before.
+
+The change is 90 lines, of which the load-bearing edit is **one**:
+
+```
+-    conditionIsTrue(conditions, "Fresh") &&
++    conditionIsSettledSatisfied(conditions, "Fresh") &&
+```
+
+where `conditionIsSettledSatisfied` accepts `true` or `not_applicable`, and
+pointedly not `unknown`. The other 89 lines are the new
+`ConnectionAcquisitionEvidence` type, one branch in `freshCondition`, and one
+branch in `collectionSucceededCondition` that mirrors the existing
+`localDeviceCollection.verdict` precedent for sources that legitimately write no
+spine run.
+
+**Regression evidence:** 305 existing tests pass unchanged —
+`connection-health.test.ts` 151/151, `connection-health-acceptance.test.ts`
+70/70, `rendered-verdict.test.ts` 84/84 — and `tsc --noEmit` is clean.
+
+Not wired to the read path. `projectConnectorSummaryConnectionHealth` in
+`server/ref-control.ts` would need to pass `acquisition` from the instance's
+`source_kind`, and that file is being actively edited by another agent. The
+runtime model is proven; the wiring is one line in a file I did not touch.
+
+## What I deliberately left alone
+
+- **The other nine conditions stay required.** Only `Fresh` gained a
+  not-applicable path, and only for one source kind. Extending this to coverage
+  is where a false green would come from, so it needs its own evidence and its
+  own argument.
+- **`classifyOwnerPaused` and the classification order.** Already correct. The
+  paused-source damage is in the pill vocabulary, not the model.
+- **`rendered-verdict.ts`.** The actor vocabulary rewrites it; the paused-pill
+  fix rewrites it; doing either piecemeal now means doing it twice.
+- **`hasAffirmativePassiveRecoveryEvidence`** (`connection-health.ts:1751`) —
+  the scheduler's passive-recovery authority. It independently requires
+  `axes.freshness === "fresh"` and `Fresh === "true"`. I did not touch it: a
+  completed import has no schedule and no next attempt, so it can never reach
+  that path, and relaxing a scheduler predicate to fix a display problem would
+  be scope I cannot justify. It is, however, the second place the same
+  fixed-required-list assumption lives, and it will need the same treatment if
+  this model is adopted.
+- **The `dirty`/projection layer.** Orthogonal, and owned by
+  `summary-evidence-projection-controller-2026-08-18.md`.
+- **Production data.** Nothing deployed, nothing committed, no database written.
+
+## Cost and risk
+
+**What breaks if the predicate changes.** Less than feared — `isHealthyConditionSet`
+is private with exactly one caller. The blast radius is `classifyHealthy`, and
+from there whatever reads `state === "healthy"`. The real risk is not
+mechanical; it is that every future `not_applicable` is a potential false green.
+That is why the rule above forbids deriving inapplicability from a missing
+answer, and why the proof-of-concept spends half its tests on that boundary.
+
+**The honest residual risk.** `not_applicable` is now load-bearing, so a bug
+that marks a condition inapplicable is a bug that turns a source green. Before
+this change such a bug was cosmetic. That is a genuine increase in the cost of
+being wrong, accepted because the alternative is a permanently dishonest display
+on 420k records that are complete and correct.
+
+**Confidence.** That the manual-import fix is right: high — it is proven by
+test, and the case admits no other honest answer. That the same shape extends
+cleanly to the stale-collector and paused cases: moderate — the evidence exists
+and the vocabulary maps, but neither is implemented, and the paused case needs a
+pill-vocabulary decision I did not make.
+
+## Related
+
+`upstream-disclosure-window-2026-08-17.md` names the same failure from the other
+side — "Imports have no upstream. They need to be first-class *not applicable*,
+not zero — the same failure this codebase already has with 'Not measured'." That
+note wanted this primitive and could not assume it. This note builds it for
+freshness; the boundary case will want it too.

+# One generation row per connection, not a generic job queue
+
+**Status:** intake. Terminal design proposed by an independent reviewer, not yet
+owner-ratified. Deliberately NOT scoped into the corrective branch that prompted it.
+**Date:** 2026-08-18
+
+## Why this note exists
+
+Five starvation bugs were found in the bounded maintenance sweep inside about
+twenty-four hours. All five have the same shape: **work that cannot progress
+consumes a shared budget, and work that can progress never runs.**
+
+1. **Checkpoint floor.** The fold read from `min(checkpoint)` across participants.
+   Three rows sat at checkpoint 0, so the floor was 0 against a 1.44M-event log.
+   Every 2s pass restarted at 0, read zero qualifying events, and repeated.
+2. **Zero-vs-null.** The first fix guarded `null`. The rows stored a literal `0`.
+3. **Phase starvation.** "Missing" discovery consumed the whole budget before
+   "generic" — the only path that classifies a row as dirty — could run.
+4. **Post-deadline skip.** Discovery expired the deadline, so the repair loop
+   skipped every candidate. 16 classified, 16 skipped, 0 repaired, on an idle
+   database.
+5. **Permanent exclusion.** The fix for #2 excluded `terminal_facts_historical`
+   rows at checkpoint 0 from the fold. Its stated exit condition was unreachable:
+   nothing marks such a row dirty, and the checkpoint advances only via the fold
+   the row is excluded from. Three production rows stranded, one an active
+   connection that could not recover.
+
+Number 5 is the one that matters most for design purposes. It was introduced *by*
+a starvation fix, written immediately after fixing the previous one, and it
+converted a livelock into a permanent exclusion. That is not an attention failure.
+It is what happens when fairness is an emergent consequence of phase order, cursor
+position, and exception paths rather than an explicit durable invariant.
+
+## The reviewer's verdict
+
+> Replace the scheduling model; keep the shipped fix only as incident mitigation.
+
+Confidence that the current model produces more bugs of this family: **0.96**.
+Confidence that a small durable reconcile queue is the right terminal shape: **0.90**.
+
+Crucially, the preferred design is **not** a generic durable job framework with
+fold, missing-repair, generic-repair, and audit job types. That would preserve the
+task-kind zoo that produced the bugs. It is:
+
+> A level-triggered, generation-based projection controller keyed by connection.
+
+## The design
+
+One durable projection-state row per connection:
+
+```
+connector_instance_id
+desired_generation
+applied_generation
+target_event_seq
+folded_event_seq
+applied_contract_version
+dirty_since
+next_attempt_at
+last_attempt_at
+attempt_count
+last_outcome
+```
+
+Every canonical change that could affect a connection's summary increments
+`desired_generation`, **preferably in the same transaction as the change**.
+Multiple changes coalesce into the same row — the row *is* the durable
+deduplicating queue entry. There is no separate queue table to keep in sync.
+
+One bounded, idempotent operation reconciles a connection:
+
+```
+reconcile(connection_id):
+  snapshot desired_generation
+  fold at most N indexed events for this connection
+  persist fold progress and yield if more remain
+  read bounded canonical facts
+  compute and write the complete desired summary
+  set applied_generation to the generation that was reconciled
+```
+
+If the connection changes mid-reconciliation, `desired_generation` advances past
+`applied_generation`, so it stays eligible automatically. A deferred or failing
+connection gets `next_attempt_at`/backoff and cannot permanently hold first
+position.
+
+## What this deletes
+
+These concepts stop existing, and with them the bugs they produced:
+
+- "missing" versus "generic" discovery phases
+- the shared minimum participant checkpoint
+- the rotating page cursor
+- process-local phase alternation
+- the first-candidate deadline exemption
+
+Missing, dirty, and code-version-stale collapse into two conditions:
+
+```
+applied_generation < desired_generation
+applied_contract_version != CURRENT_VERSION
+```
+
+**Both of those conditions would have prevented a bug this codebase actually
+shipped.** `applied_generation < desired_generation` is derived, not remembered,
+so bug #5 is unrepresentable — a row cannot be stranded by a predicate that
+forgot to let it back in. And `applied_contract_version != CURRENT_VERSION` is
+exactly the check that was missing when production ran fold logic version 5 while
+every committed branch was at 4: a clean build shipped a binary older than its own
+data, the version guard failed closed, and 26 of 28 evidence rows went unreadable
+with no signal beyond a fleet of grey pills.
+
+## Bounds are still required
+
+The controller shape does not remove the need for hard bounds:
+
+- bounded indexed event pages
+- PostgreSQL `statement_timeout` and `lock_timeout`
+- bounded SQLite query shapes, or interruption where the driver allows it
+- a soft pass admission deadline
+- a maximum number of units per wake
+
+The reviewer's P1-2 stands independently of the redesign: the current 2000ms
+`maxDurationMs` is a cooperative admission hint, not a wall-clock or database
+occupancy bound. Measured on production *after* removing an unrelated CPU
+contention problem, a pass still reported `repair_duration_ms: 5322` with skipped
+candidates. If a unit cannot be hard-cancelled, it does not belong inside a
+claimed 2-second maintenance loop.
+
+## The three invariants
+
+The reviewer rejected the single-invariant framing ("a pass that finds candidates
+must repair at least one") as insufficient — it conflates repair success with
+scheduling and does not bound a pathological unit. Three independent, separately
+testable invariants are required:
+
+**A. Bounded yield.** No operation may run between durable yield points unless its
+worst-case work is bounded or it has enforceable cancellation.
+
+**B. Monotonic outcome.** Every attempted work item must durably advance a cursor,
+complete, defer with a future eligibility time, back off, or terminate. An
+identical no-op retry cannot repeat forever.
+
+**C. Bounded fairness.** Every continuously eligible item and nonempty task class
+must receive an attempt within a defined number of scheduler turns, **across
+process restarts**.
+
+Invariant C is the one the current implementation cannot satisfy: fairness lives
+in module-local variables (`nextDirtyAfterId`, `nextFirstObservationPhase`) whose
+convergence bound vanishes on restart.
+
+## The audit becomes a backstop
+
+The hot path should not recompute fleet-wide aggregates. Expensive facts such as
+record counts should be maintained incrementally where practical and verified by a
+slower paged audit. The periodic sweep stops being the primary repair engine and
+becomes what it should have been: a detector of missed invalidations that marks
+connections behind. Orphan detection belongs there too, not in the latency-
+sensitive loop.
+
+## Scope discipline
+
+The reviewer was explicit that this redesign should **not** be added to the
+corrective branch. That branch finishes a bounded list:
+
+- advance fairness from the last *attempted* candidate, not the last fetched
+  page member — **done** (`ab28764f2`)
+- repair `terminal_facts_historical` re-entry and boundary stamping — **partially
+  done** (`078b72e3a` prevents new stranding; already-stranded rows still need a
+  one-time re-entry path, in progress)
+- the four adversarial tests, plus below-page-limit, above-page-limit, and
+  restart cases — **partially done**, restart case outstanding
+- hard per-query/per-unit bounds, and an honest name for the pass deadline
+- no-progress telemetry and alerting
+- durable fairness, or fairness derived from durable per-item attempt state —
+  **deliberately deferred to this note's design**, since it needs a schema change
+  and a different discovery query shape
+
+Durable fairness is the item that most clearly belongs here rather than there:
+implementing it in the current model means adding per-item attempt columns and
+reshaping the discovery query, which is most of the projection-state row anyway.
+Doing it twice would be waste.
+
+## Open questions
+
+- Does `desired_generation` increment in the same transaction as every canonical
+  change, or is a trigger acceptable? Same-transaction is stated as preferred;
+  the cost is touching every writer.
+- What is the migration path for the existing `connector_summary_evidence` rows,
+  including the three currently stranded at checkpoint 0?
+- Does the audit backstop need its own fairness guarantee, or is a slow full
+  rotation sufficient given it is no longer the primary repair path?
+- SQLite parity: `statement_timeout` has no direct equivalent. Is a bounded query
+  shape provably sufficient, or is driver-level interruption required?
+
+## Provenance
+
+Independent design review of the bounded maintenance sweep, 2026-08-18, conducted
+against `sweep-design-review-20260818.zip` (the four starvation bugs, the shipped
+minimum-one fix, and the supporting patches). The reviewer retracted one
+production measurement from that packet after it was shown to be confounded by an
+uncapped embedding transformer competing with PostgreSQL — the code-level
+counterexamples and the structural conclusion were unaffected.
+
+Related: `connector-sidecar-packaging-2026-08-17.md` and
+`upstream-disclosure-window-2026-08-17.md` share the shape of a component whose
+correctness depends on a peer's version with nothing verifying the pair.

+# Surfacing a shrinking upstream disclosure window
+
+**Status:** intake. Not an OpenSpec change; no requirement is proposed yet.
+**Date:** 2026-08-17
+
+## The observation that prompted this
+
+PDPP holds two H-E-B orders for the owner, both captured in the same scan on 2026-07-15:
+
+| id | date | status | total |
+|---|---|---|---|
+| `HEB20169324473` | 2023-08-09 | Order canceled (`SHORTED`) | $293.98 |
+| `HEB20607368035` | 2023-08-19 | Delivered | $382.67 |
+
+H-E-B now displays only the second one to that account.
+
+The owner's inference is the load-bearing one: **PDPP scrapes what the account UI shows, so if it
+captured the first order, H-E-B was showing it then.** The record did not move. The provider's
+disclosure did.
+
+That is the product working exactly as intended — PDPP holds data the provider no longer surfaces.
+But the app cannot say so. Its dashboard shows "2 orders" today and would show "2 orders" after a
+fresh run that finds nothing. Something important happened and the product is silent about it.
+
+For a tool whose purpose is outrunning deletion, "the source is disclosing less than it used to"
+is not noise. It is the alarm.
+
+## What the system already has
+
+- Per-source checkpoint: `{"checkpoint": "2023-08-19", "fingerprints": {...}}`
+- `fetched_at` on every record
+- Scan-termination reasons in the H-E-B connector distinguishing `pagination_exhausted` from
+  `selector_drift`, `pagination_metadata_absent`, `source_auth_or_challenge`
+  (`packages/polyfill-connectors/connectors/heb/index.ts:320-335`)
+
+What is missing is durable evidence of *why a scan stopped* and *how far back it reached*. For
+`cin_c875ca3ec8b6ce2c283a4288` no such evidence was stored, and there is no run history at all —
+so today we cannot distinguish "H-E-B showed us everything" from "we hit a wall."
+
+## The proposed primitive: an observed boundary, not availability
+
+Per successful run, one value: **the oldest item the provider displayed**, recorded only when the
+scan proves it reached the end of its range. Comparing across runs yields a moving frontier.
+
+The product could then say something entirely factual:
+
+> H-E-B showed orders back to 2023-08-09 in July 2026; today it goes back to 2023-08-19.
+> 1 stored order is no longer displayed.
+
+Every clause is an observation. The conclusion — *their retention window is closing* — is the
+owner's to draw, and they can draw it, because they know whether they shopped in 2024.
+
+## Hard constraints
+
+**1. A moving boundary is information about the provider, never an annotation on a record.**
+This is the one absolute. Nothing in this design may mark a stored record deleted, stale, or
+suspect. Deliberately: no connector in the fleet emits deletions today — verified, zero occurrences
+of a delete/tombstone emission across `packages/polyfill-connectors/connectors/` — so provider
+erasure structurally cannot propagate into the owner's copy. Introducing a path that annotates
+records based on absence would give that up for a signal that is frequently wrong.
+
+**2. Absence is evidence only when the scan proves it covered the range.**
+A run ending `pagination_exhausted` makes absence meaningful. A run ending `selector_drift` or
+`source_auth_or_challenge` makes it meaningless. Without a stored termination reason there is no
+signal, and the correct output is "unknown."
+
+**3. Do not encode provider retention policies.**
+"H-E-B keeps 18 months" is undocumented, changes silently, and varies by account and region. A
+wrong constant produces confident lies. The empirically observed window is strictly better: it is
+measured, not asserted, and it survives the provider changing policy without telling anyone.
+
+## Edge cases that make a *general* solution hard
+
+- **Silent auth degradation.** A session expiring into a logged-out-but-200 view returns no items,
+  reports pagination exhausted, and yields a boundary of nothing — indistinguishable from a total
+  purge. The nastiest false positive, and the reason constraint 1 is absolute.
+- **Not every source has an ordering.** Contacts have no time axis. Notion pages are edited, so
+  recency is not age. Gmail's "oldest visible" depends on the query. A single scalar frontier fits
+  perhaps half the fleet and produces meaningless numbers for the rest.
+- **Scope change mimics retention.** Leaving a Slack channel removes its history from view; a plan
+  downgrade hides older data; a provider splitting history by store looks like shrinkage. No
+  boundary comparison can tell these from deletion.
+- **Retention is rarely uniform.** Amazon keeps orders but drops invoice PDFs; Slack's free tier
+  hides messages but keeps files; Gmail retains mail but purges trash at 30 days. One per-source
+  boundary cannot express "text kept, attachments gone," and per-stream boundaries multiply the
+  connector burden.
+- **Imports have no upstream.** Google Maps and the WhatsApp exports are one-shot files. They need
+  to be first-class *not applicable*, not zero — the same failure this codebase already has with
+  "Not measured" (see `add-honest-uncollected-source-states`).
+- **Contiguity assumptions are false.** "Orders are sequential, so a gap means deletion" breaks on
+  a month with no shopping. The owner's own H-E-B data is two orders ten days apart and then
+  nothing — a gap that is a fact about their life, not their provider.
+
+## Recommended shape
+
+**Opt-in per connector, not a universal contract.** Connectors with a genuine monotonic frontier
+and a provable pagination stop — orders, transactions, messages — report a boundary. Everything
+else reports nothing, and nothing is fine. A signal present on eight connectors and honest beats
+one present on twenty-four and wrong.
+
+**Runtime owns the bookkeeping.** The author declares the scanned range and the termination reason;
+the runtime derives the boundary and its movement. A connector must never assert that something is
+gone.
+
+**Fail closed.** No termination reason means no boundary claim. A lazy or broken connector produces
+"unknown," never a false purge.
+
+**Machine reports, human interprets.** State the observation; leave the conclusion to the owner.
+That is not a cop-out — it puts the inference where the context actually lives. The owner knew
+instantly that PDPP could not have collected an invisible order; no rule authored here would have
+encoded that.
+
+## Honest caveat on feasibility
+
+This is reasoned from one connector and a day of code reading. The fleet has not been surveyed for
+how many connectors could actually satisfy constraint 2. Today's evidence argues for pessimism:
+Slack emitted duplicate coverage for every multi-archive run since inception, and a Codex source
+was rendered unmeasurable by a single stale store name. If the existing, simpler coverage contract
+is unevenly met, a boundary contract will be too. Expect "unknown" from a meaningful fraction of
+the fleet for a long while — and prefer that to false confidence.
+
+## Relationship to existing work
+
+Same failure shape as several open items: a derived value that goes quietly stale because nothing
+watches whether its source changed. Compare `add-projection-contract-versioning` (input checkpoints
+cannot see a formula change), `make-local-coverage-tolerate-unexpected-stores` (a stale store name
+discards a valid proof), and `add-durable-connection-account-identity` (identity derived from a
+provisional binding key). The recurring principle is worth stating once, somewhere durable:
+**derive nothing durable from a value that may be provisional, and watch anything you do derive.**

   `docs/reference/local-collector.md`§"Deployment Posture: Published vs Dev".
 
+## Signal Desktop prerequisites
+
+Signal is a **local-collector-only** connector: unlike Slack (`slackdump`) or
+Google Messages (`gmcli`), its sidecar tool cannot ship inside the Core
+server image. The manifest declares a `desktop_session` runtime binding, and
+the engine resolves that to `local_device` placement and refuses server-side
+placement outright. This is by design, not a temporary gap &mdash; see
+`design-notes/connector-sidecar-packaging-2026-08-17.md` for the full
+evidence trail (a container hits four successive failures: missing file,
+no D-Bus session, uid mismatch, AppArmor denial).
+
+**Why:** Signal Desktop's SQLCipher database key is stored encrypted in
+`~/.config/Signal/config.json` (`encryptedKey`) and unwraps only through a
+session-bound OS keyring &mdash; KWallet/GNOME Keyring (`libsecret`) on
+Linux, Keychain on macOS, DPAPI on Windows. Check which backend your
+Signal Desktop uses:
+
+```bash
+cat ~/.config/Signal/config.json
+```
+
+- `"safeStorageBackend": "kwallet6"` (or `gnome_libsecret`, etc.) &mdash; the
+  key only unwraps inside the owner's own logged-in desktop session. Run the
+  collector directly on that machine, logged in as that user, outside any
+  container.
+- `"safeStorageBackend": "basic_text"` &mdash; the key is stored unwrapped.
+  A server-side path is technically possible in this configuration, but it
+  is not what this connector is built or tested for; treat it as a
+  documentation note, not a supported deployment target.
+
+**Install `sigtop`** (github.com/tbvdm/sigtop, ISC license) &mdash; the CLI
+this connector spawns as an arms-length subprocess to decrypt and read
+Signal Desktop's database, the same "sidecar" pattern the `slack` connector
+uses for `slackdump`:
+
+```bash
+# Linux: pkg-config needs the libsecret headers to build the safeStorage
+# unwrap. If you cannot install system-wide (no root), download the .deb
+# with apt-get download (works without sudo) and extract it locally, then
+# point PKG_CONFIG_PATH/CGO_LDFLAGS at the extracted tree instead of
+# installing system-wide.
+sudo apt install libsecret-1-dev pkg-config   # Debian/Ubuntu
+# or: dnf install libsecret-devel pkgconf-pkg-config   # Fedora
+
+GOBIN=~/.local/bin go install github.com/tbvdm/sigtop/cmd/sigtop@latest
+```
+
+Note the real import path is `github.com/tbvdm/sigtop/cmd/sigtop` &mdash;
+`go install github.com/tbvdm/sigtop@latest` (without `/cmd/sigtop`) fails
+with "module ... found, but does not contain package ...".
+
+**Verify the binary actually works** &mdash; `sigtop -v` and `sigtop version`
+are NOT valid subcommands (there is no version flag at all); use a real
+subcommand instead:
+
+```bash
+sigtop check-database   # fast SQLCipher integrity check against the local DB;
+                         # exits 0 with no output on success
+```
+
+If Signal Desktop is running, close it first &mdash; sigtop needs unlocked
+read access to `db.sqlite`/`db.sqlite-wal`/`db.sqlite-shm`.
+
+**Point the collector at `sigtop`** if it is not on `PATH` (a custom
+`GOBIN`, a non-standard install location, etc.):
+
+```bash
+export SIGTOP_BIN=/absolute/path/to/sigtop   # default: "sigtop" on PATH
+```
+
+`resolveSigtopBin`/`runSigtop` in `packages/polyfill-connectors/connectors/signal/index.ts`
+implement this resolution; a missing binary fails fast with a message
+naming both the install command and the `SIGTOP_BIN` override, rather than
+an opaque `ENOENT`.
+
+**Building `@pdpp/local-collector` from source for Signal support**: if your
+installed `@pdpp/local-collector` predates Signal (`advertise` does not list
+`signal` under `bundled_connectors`), rebuild from a checkout that has the
+connector. The collector's `tsconfig.build.json` `include` list is the
+package's actual shipping manifest &mdash; a connector must be listed there
+(and its test-only fixture files that pull in `better-sqlite3` must be
+listed under `exclude`, the same way `imessage/fixtures.ts` and
+`signal/fixtures.ts` are) or its compiled `.js` never reaches the tarball,
+even if the connector is registered in `collector-registry.ts` and shows up
+under `advertise`. A collector shipping only `collector-definition.js` for a
+connector (no `index.js`) will advertise it but fail at spawn time with
+`spawn tsx ENOENT` (falling back to running uncompiled `.ts` source, which
+needs a `tsx` binary this package deliberately does not depend on).

+## Context
+
+`connector_instances.status` admits `active`, `paused`, `revoked`, `draft`. Before this change, `paused` was reachable only by data transplant or direct SQL, and escapable only through `resumePausedConnectionAfterCredentialCapture` — a side effect of the static-secret credential-capture route.
+
+The owner asked for pause and resume directly, and two stranded production connections proved the state needed a real exit, not just an entrance.
+
+## Goals
+
+- One coherent state machine: `active <-> paused`, `revoked -> active` via reactivate.
+- Wrong-state refusals are typed and distinguishable, never a generic inactive error.
+- A paused connection is visible in the console and carries its own way back.
+
+## Decisions
+
+### Pause ships as an owner action
+
+The alternative was to ship resume alone (enough to rescue the stranded rows) and defer pause until an owner asked twice. Rejected: a state that can be left but not entered is exactly the incoherence that produced this defect, and the state, the storage constraint, and the owner-facing spec language for it already existed. Shipping resume alone would have left `paused` reachable only by transplant — still a trapdoor, just a monitored one.
+
+Pause is genuinely distinct from revoke and not redundant with it. Revoke means "stop collecting and treat the authorization as withdrawn". Pause means "stop collecting, keep the credential, resume when I say". A source you can pause without re-authorizing is the feature the owner named.
+
+### Pause and resume are zero-cascade
+
+Both are pure status flips on the connector-instance row, matching revoke/reactivate. Neither touches records, credentials, grants, schedules, or the spine. Pause deliberately does NOT revoke the credential — retaining it is the entire difference from revoke, and it is what makes resume a single click rather than a re-authorization.
+
+### Wrong-state refusals get their own codes
+
+The namespace resolver reports any status mismatch as `connector_instance_inactive` (400). Both routes re-label it: resume against a non-paused target returns `connector_instance_not_paused` (409); pause against a non-active target returns `connector_instance_not_active` (409). This mirrors reactivate's existing `connector_instance_not_revoked` and lets a caller distinguish "wrong state" from "no such connection" without parsing prose.
+
+### The explicit owner route is not restricted by binding kind; the automatic hooks still are
+
+The shared `applyResume` primitive takes an optional `requireSourceBindingKind`. The automatic resume hooks — credential capture and run admission — pass `historical_archive`, keeping the implicit, non-owner-initiated path as narrow as it was. The explicit owner routes pass nothing: when the owner clicks Resume, the binding kind is not the server's business, and restricting it would have re-created the trap for every other paused connection.
+
+### Credential freshness is delegated to the next run
+
+Resume does not validate or supply a credential, matching reactivate. A resumed connection whose credential has expired surfaces a typed credential error on its next run through the existing health projection. Validating at resume time would duplicate that machinery and could refuse a resume the owner legitimately wants (for example, a file-import connection that authenticates to nothing).
+
+### A missing import directory is an infrastructure fault, not owner data loss
+
+`isManualUploadBinding` returning null for an unusable binding meant the run silently received no import-dir env var and reported `source_incomplete` — which reads as "your archive was incomplete" when the truth is "this server was told to read a path that is not on this disk". The resolver now stats the directory and throws `manual_upload_import_dir_missing` naming the path, the env var, and the connection. This is the silence that let two intact archives sit unnoticed.
+
+## Risks / Tradeoffs
+
+- **Pause could be mistaken for revoke.** Mitigated by console copy stating that data and the credential are retained, and by keeping the two actions visually and textually distinct.
+- **A paused connection stops collecting silently.** Mitigated by rendering `paused` as a first-class status and surfacing the connection with a Resume action rather than hiding it as revoked connections are hidden.
+- **Statting the import directory adds a filesystem call per manual-upload run.** Negligible against a run that then reads the archive, and it converts a silent misattribution into an actionable error.
+
+## Acceptance Checks
+
+- Resuming a paused connection returns 200 and the row becomes `active`; a second resume returns `connector_instance_not_paused` (409).
+- Pausing an active connection returns 200 and the row becomes `paused`; a second pause returns `connector_instance_not_active` (409).
+- Pause and resume leave record counts, credentials, grants, and schedules unchanged.
+- A paused connection renders a `paused` status and a Resume action in the console.
+- A manual-upload run whose `import_dir` is absent fails with `manual_upload_import_dir_missing` naming the missing path and env var.
+- A transplanted `historical_archive` binding is not claimed by the manual-upload resolver.

+## Why
+
+`paused` has been a valid `connector_instances.status` since the schema's first CHECK constraint, and the owner-facing specs already promise pause and resume as per-instance actions. Neither existed. No production code path ever wrote `paused`, and only one path ever cleared it — a side effect of storing a static-secret credential.
+
+That left `paused` a state with no entrance and, for any connection that reached it another way, no exit. Two of the owner's connections (419,290 records) arrived pre-paused from an archive transplant and could not be recovered: `run` refused them as inactive, `reactivate` refused them as not-revoked, the console had no control because `SourceStatusKind` had no `paused` member, and file-import connections authenticate to nothing so the credential-capture side effect never fired.
+
+## What Changes
+
+- Add owner-initiated `pause` (active -> paused) and `resume` (paused -> active) as first-class connection actions, on both the owner-agent bearer surface and the owner-session reference surface.
+- Add `connector_instance_not_paused` (409) and `connector_instance_not_active` (409) so each action refuses a wrong-state target with a typed, distinguishable code.
+- Make `paused` a first-class `SourceStatusKind` the console renders and explains, with a Resume control on a paused connection and a Pause control on an active one.
+- Keep the narrow automatic resume for recovered `historical_archive` connections (credential capture and run admission) unchanged, so repairing a credential still resumes that row without a second owner step.
+- Fail loudly when a manual-upload binding's `import_dir` is absent on the host, naming the missing path and env var instead of reporting a bare `source_incomplete`.
+
+## Capabilities
+
+Modified:
+- `reference-connector-instances`
+
+## Impact
+
+- Pause and resume are zero-cascade status flips. Records, credentials, grants, schedules, and the audit spine are untouched by both.
+- Pause is deliberately NOT a substitute for revoke: it stops collection while keeping the credential, so it carries no credential-revocation or grant-narrowing semantics.
+- A manual-upload run whose artifact directory is missing now fails with a typed, actionable error rather than an owner-blaming coverage verdict.

+## ADDED Requirements
+
+### Requirement: Owner-Initiated Connection Pause And Resume
+
+The reference implementation SHALL expose connection pause and connection resume as owner-initiated, connection-scoped actions keyed on exactly one `connector_instance_id`.
+
+Pause SHALL transition a connection from `active` to `paused`. Resume SHALL transition a connection from `paused` to `active`. Both SHALL be zero-cascade status flips: they SHALL NOT delete, rewrite, or hide already-collected records; SHALL NOT revoke, rotate, or erase stored credentials; and SHALL NOT alter disclosure grants, schedules, or the audit spine.
+
+Pause SHALL remain distinct from revoke. Pause stops future collection while retaining the connection's stored credential so that resume requires no re-authorization. Revoke SHALL continue to express a withdrawn authorization.
+
+Both actions SHALL be reachable on the owner-agent bearer control plane and on the owner-session reference control plane. Neither SHALL be reachable over `/mcp` or by a client grant token.
+
+A paused connection SHALL be refused by run admission until it is resumed. Resume SHALL NOT itself validate or supply a credential; a resumed connection whose credential is missing or expired SHALL surface a typed credential error on its next collection run.
+
+#### Scenario: Owner pauses an active connection
+
+- **WHEN** the owner pauses a connection whose status is `active`
+- **THEN** the connection's status SHALL become `paused`
+- **AND** its collected records, stored credential, disclosure grants, schedule, and audit spine SHALL be unchanged
+- **AND** subsequent run admission for that connection SHALL be refused while it remains paused
+
+#### Scenario: Owner resumes a paused connection
+
+- **WHEN** the owner resumes a connection whose status is `paused`
+- **THEN** the connection's status SHALL become `active`
+- **AND** its collected records SHALL be unchanged
+- **AND** the connection SHALL become eligible for run admission
+
+#### Scenario: Wrong-state pause and resume are typed and distinguishable
+
+- **WHEN** the owner resumes a connection whose status is not `paused`
+- **THEN** the reference SHALL refuse with `connector_instance_not_paused`
+- **AND** **WHEN** the owner pauses a connection whose status is not `active`
+- **THEN** the reference SHALL refuse with `connector_instance_not_active`
+- **AND** neither refusal SHALL mutate the connection
+
+#### Scenario: Unknown or foreign connection
+
+- **WHEN** a pause or resume names a connection that does not exist or belongs to another owner
+- **THEN** the reference SHALL refuse with `connector_instance_not_found`
+- **AND** SHALL NOT disclose whether the connection exists
+
+#### Scenario: Paused is an owner-visible status with a way back
+
+- **WHEN** the owner views a connection whose status is `paused`
+- **THEN** the console SHALL render `paused` as a first-class status distinct from revoked, syncing, and setup-in-progress
+- **AND** SHALL present a resume action for that connection
+- **AND** SHALL state that collected data is retained
+
+### Requirement: Manual Upload Import Directory Absence Is A Typed Failure
+
+The reference implementation SHALL verify that a manual-upload connection's `import_dir` exists as a directory on the host before a run is given the binding's import-directory environment variable.
+
+When the directory is absent or is not a directory, the reference SHALL fail the run environment resolution with a typed `manual_upload_import_dir_missing` error naming the missing path, the binding's `import_dir_env_var`, and the `connector_instance_id`. The reference SHALL NOT report this condition as a bare coverage or completeness verdict, because the fault is host or binding configuration rather than an incomplete owner-supplied archive.
+
+A source binding that is not a manual-upload binding SHALL continue to resolve to no manual-upload environment fragment without raising this error.
+
+#### Scenario: Missing import directory names what is missing
+
+- **WHEN** a manual-upload connection's `import_dir` does not exist on the host
+- **THEN** run environment resolution SHALL fail with `manual_upload_import_dir_missing`
+- **AND** the error SHALL name the missing path, the import-directory environment variable, and the connection
+- **AND** the run SHALL NOT report the condition as an incomplete owner-supplied source
+
+#### Scenario: Import path that is not a directory
+
+- **WHEN** a manual-upload connection's `import_dir` exists but is not a directory
+- **THEN** run environment resolution SHALL fail with `manual_upload_import_dir_missing`
+
+#### Scenario: Non-manual-upload binding is unaffected
+
+- **WHEN** a connection's source binding is not a manual-upload binding
+- **THEN** manual-upload run environment resolution SHALL yield no environment fragment
+- **AND** SHALL NOT raise `manual_upload_import_dir_missing`

+## Context
+
+PDPP already had the right mechanism and the right terminal vocabulary.
+`run.abandoned` is a first-class terminal event in `check-run-terminal.sql`,
+`run-history-writer.ts`, and the `terminal_status` contract in
+`openspec/specs/reference-implementation-architecture/spec.md`. A boot
+reconciler already wrote it. The design was disabled by one identity defect,
+and the surrounding machinery — a drain, a wall clock, a second reconciler —
+existed to compensate for the resulting silence.
+
+This change is therefore mostly subtraction. The one substantive addition is
+durable identity; the deletions are its consequence.
+
+## Goals / Non-Goals
+
+**Goals:**
+
+- Every run reaches exactly one durable terminal state, written by exactly one
+  writer.
+- An interrupted run is named `abandoned`, never `failed`.
+- A successor container can adjudicate its predecessor's orphans.
+- No adjudication decision depends on a tuned time threshold.
+
+**Non-Goals:**
+
+- Finishing in-flight work during shutdown.
+- Committing staged cursors under interruption.
+- A generic cross-table "interrupted work engine". Six boot reconcilers should
+  share a *predicate*, not an executor; a unified engine would need per-table
+  SQL, projections, and terminal vocabularies injected into it, which is
+  relocation rather than decomplecting.
+
+## Decisions
+
+### The successor adjudicates; the dying owner writes nothing
+
+The dying process is the wrong writer because it cannot be relied on to run at
+all. A `kill -9` gets no shutdown path, so any design that needs the owner to
+write its own terminal state has an unhandled case by construction.
+
+This is the layering mature systems ship. Temporal's server has no
+crash-detection channel and converts worker silence into a recorded outcome
+with a timer alone; its `WorkerStopTimeout` — "the time delay before hard
+terminate worker" — defaults to **0s**, so it does not wait for in-flight work
+by default. Kafka's successor performs the recovery: `InitProducerId` "Bumps up
+the epoch of the PID, so that the any previous zombie instance of the producer
+is fenced off" and "Recovers (rolls forward or rolls back) any transaction left
+incomplete by the previous instance." Primary sources for both, with quotes and
+access dates, are in the research entry
+`ai/research/pdpp/interrupted-work-needs-an-owner-fenced-terminal-state-not-a-graceful-shutdown-because-dockers-10s-stop-is-shorter-than-the-work.md`
+(claims A, sources `sdk-go-worker-base`, `temporal-activity-failures`,
+`kip-98`).
+
+Alternative: retarget the controller path to write `run.abandoned` instead of
+deleting it. Rejected because two writers racing for one run's terminal event
+is worse than one. The boot reconciler is the better writer: it reads the
+append-only spine rather than the `controller_active_runs` flight table, it is
+idempotent on `caused_by_event_id` through the
+`spine_run_abandoned_cause_unique` partial index, and it aborts boot on error
+instead of swallowing it.
+
+### `abandoned` stays distinct from `failed`
+
+Interruption is Kubernetes' `Unknown`, not `False`. Kubernetes keeps the two
+distinct because they drive different remediation — node `Unknown` yields an
+`unreachable` taint, `False` yields `not-ready`. The same holds here: `failed`
+on a bank connector means ask the human; `abandoned` means nobody knows, and
+the normal schedule will pick it up. Collapsing them is what pages an owner for
+a deploy.
+
+The cost of the collapse is measured, not theoretical: of 134 production runs
+recorded as `run.failed`/`controller_restarted`, 55 had staged a cursor and 34
+had durably ingested a batch before being written down as plain failures.
+
+### Durable identity beats an env var
+
+Setting `PDPP_CONTROLLER_ID` in the run command would fix the filter. It is
+rejected as the *default* because its failure mode is silent. Production runs
+from a hand-rolled `docker run`; an identity that depends on an operator
+reproducing a flag on every container recreation is one omission away from
+reopening this exact defect, with no signal that it has reopened. That is how
+the defect hid for three months. Reading the value from the same database that
+holds the runs makes the correct answer the default. `PDPP_CONTROLLER_ID` is
+kept as an override so a genuine multi-controller deployment can still
+partition ownership.
+
+`os.hostname()` survives only as the seed for the first row, never as the live
+identity. The boot epoch still advances per boot; only the identity is stable,
+so adjudication still distinguishes "a prior incarnation owned this" from "I
+own this".
+
+### The drain is deleted, not lengthened
+
+Rejected on measurement. Production sets no `--stop-timeout`
+(`docker inspect pdpp-core-prod-drain` returns `StopTimeout=<nil>`), so
+Docker's 10s default governs, and `--stop-timeout` is fixed at container
+creation — Docker has no equivalent of systemd's runtime `EXTEND_TIMEOUT_USEC=`
+extension. Only 2 of 17 connectors finish inside 10s at p95; slack's p95 is
+4052.8s. The gap is two orders of magnitude and is not closable by tuning.
+
+The drain was observed in production failing exactly that way, logging
+`{"drained":0,"elapsedMs":5000,"timedOut":1,"msg":"connector run drain complete"}`.
+It is a negative, not a small win: it consumes half the SIGKILL budget doing
+nothing while making the failure look handled.
+
+Only the shutdown call site is removed. `drainActiveRuns` stays on the
+controller, where it means "await in-flight runs" — 137 references exist on the
+base branch and 136 remain, the single removal being the shutdown call. Sidekiq
+draws the same line between *quiet* and *drain*.
+
+### The epoch fence, not a wall clock, decides in-flight ownership
+
+A wall-clock reaper must guess a threshold and can be wrong in both directions.
+River documents the cost in its own config comment — "this can result in repeat
+or duplicate execution of a job that is not actually stuck but is still
+working" — and Oban's Lifeline carries the same caveat. An epoch fence needs no
+guess: a unit stamped with epoch E, observed by epoch E' ≠ E, is *provably*
+orphaned.
+
+A `NULL` owner epoch must be swept, since no live process claims it. On
+PostgreSQL this arm is spelled out explicitly rather than left to
+`IS DISTINCT FROM`, because `owner_epoch IS DISTINCT FROM NULL` reduces to
+`owner_epoch IS NOT NULL` and would spare exactly the legacy rows that most
+need reclaiming.
+
+## Corrections to the research entry
+
+The research entry is `settled` and its prior-art layer holds, but
+implementation measurement refuted four of its claims. The spec deltas reflect
+the measurements, not the entry.
+
+1. **"The leak is live and accruing" — false.** The entry inferred acceleration
+   from re-measuring 121 as 123 forty minutes later. Those two extra rows were
+   runs the live container had started minutes earlier — live work, not new
+   orphans. The newest true orphan is 2026-07-10. The leak stopped because the
+   *dishonest* path started catching what the honest one could not see; two
+   defects were masking each other.
+
+2. **Deleting `MANUAL_UPLOAD_IN_FLIGHT_STALE_MS` rests on an epoch that did not
+   exist.** The entry said the wall clock answered "a question the epoch
+   answers exactly", assuming an epoch was available on that table. It was not:
+   `manual_upload_artifacts` had no epoch column, confirmed absent on the live
+   database. Deleting the clock without adding the column would have been a
+   straight regression — the sweep would have had nothing left to distinguish
+   live work from dead. The column is the substantive change; the deletion is
+   the consequence.
+
+3. **"The two reconcilers race on the same runs" — false.** They are fully
+   disjoint: zero of the 134 `controller_restarted` runs ever also received a
+   `run.abandoned`. This strengthens the case for deleting the controller path
+   rather than weakening it — there was no overlap proving the boot path
+   already covered those runs, so the identity fix had to land first.
+
+4. **The §11 gate is answered NO.** The entry asked whether connectors emit
+   bounded `DETAIL_COVERAGE` with `covered == considered` and a non-null
+   boundary. Zero of 34,928 `run.detail_coverage_declared` events in production
+   carry `boundary`, `slice_start`, or `slice_end`. Committing staged cursors
+   under `INTERRUPTED` would therefore fabricate denominators. That stage is
+   correctly not shipped and is an explicit non-goal.
+
+## Risks / Trade-offs
+
+- [A backfill adjudicates live work] -> The repair tool excludes runs belonging
+  to the newest `controller.booted` epoch. This is load-bearing: the first dry
+  run against production reported 123 because it picked up two runs the live
+  container had started ninety seconds earlier. Adjudicating those would have
+  declared live work abandoned and freed the connection for a competing run,
+  reintroducing the exact duplicate-execution hazard the epoch fence exists to
+  avoid. Excluding the newest epoch fixes it with no threshold to tune; the
+  dry run then reported 121, matching the measured backlog.
+- [Deleting the controller path loses stale-claim cleanup] -> It does not. The
+  function is retained as `releaseAbandonedControllerRunClaims` and still
+  releases stale `controller_active_runs` rows, because
+  `reconcileBrowserSurfaceLeasesAfterBoot` reads that table to decide which
+  leases are still held. Releasing a claim and reporting on the work are
+  separate jobs.
+- [No drain means Chromium residue leaks] -> Chromium residue is still cleaned
+  at next boot by `profile-lock.ts`.
+- [A multi-controller deployment adjudicates a peer's live runs] -> The boot
+  reconciler still filters on `controller_id`, and `PDPP_CONTROLLER_ID`
+  partitions ownership. Only the repair tool ignores `controller_id`, and it is
+  documented as single-controller-only, with `--connector` scoping for anyone
+  else.
+- [Legacy rows without an epoch] -> Both new columns are NULL-tolerant. A NULL
+  owner epoch is treated as unclaimed and swept; a NULL `controller_id` is
+  treated as ours under the single-controller assumption, which is the
+  pre-existing behavior.
+
+## Migration Plan
+
+1. Land durable identity first. It is behavior-preserving on a host whose
+   hostname was already stable, and on a container host it only makes the
+   existing ownership filter match reality.
+2. Run the repair tool's dry run, confirm the scope, then `--apply` with
+   pre-image snapshots. Reversible: it only adds terminal events where none
+   exist, and never edits or deletes an existing event.
+3. Delete the controller failure path only after identity is durable, so the
+   boot reconciler demonstrably covers the cases it covered.
+4. Delete the drain and fence the manual-upload sweep. Both are independent of
+   the above.
+5. Roll back by restoring the controller path and the drain call site. Already
+   written `run.abandoned` events remain valid and correct.

+## Why
+
+A run interrupted by container replacement never received an honest terminal
+state, and the mechanism built to give it one was silently disabled.
+
+`resolveControllerId` fell back to `os.hostname()`, which under Docker is the
+container id and is fresh on every `docker run`. `PDPP_CONTROLLER_ID` is unset
+in production, so the boot reconciler's ownership filter
+`COALESCE(data_json->>'controller_id', $2) = $2` excluded every prior
+container's orphans — a lost-and-found that only accepted items it had lost
+itself. Production holds 1,231 `controller.booted` events across 1,153 distinct
+controller ids; the one host with a stable id (`peregrine`, non-Docker, 18 boots
+under one id) is the only place the mechanism ever worked.
+
+The measured cost: 121 `run.started` events spanning 2026-05-15 to 2026-07-10,
+across 106 distinct controller ids, carried no terminal event of any kind. A
+second, cruder path picked up part of the slack with the wrong vocabulary —
+of 134 runs it recorded as `run.failed`/`controller_restarted`, 55 had staged a
+cursor and 34 had durably ingested a batch first. Those were interruptions
+recorded as failures, and the two states have different remedies: `failed` on a
+bank connector means ask the human, `abandoned` means nobody knows and the
+normal schedule will pick it up.
+
+The shipped 5s SIGTERM drain cannot close this. Production sets no
+`--stop-timeout`, so Docker's 10s default governs, and only 2 of 17 connectors
+finish inside 10s at p95. It was observed in production logging
+`{"drained":0,"elapsedMs":5000,"timedOut":1}` — burning its whole budget and
+abandoning the run anyway.
+
+## What Changes
+
+- Make controller identity durable in a `controller_identity` row, seeded from
+  the hostname on the first boot that finds the table empty and read back
+  unchanged thereafter, so a successor container inherits the ownership filter
+  that lets it adjudicate its predecessor's orphans. `PDPP_CONTROLLER_ID` still
+  wins when set. The boot epoch still advances per boot.
+- Stop recording interrupted runs as failures. The controller path no longer
+  emits `run.failed`/`controller_restarted`; it retains only its stale-claim
+  release, renamed to say what it does. The boot reconciler becomes the single
+  writer of an interrupted run's terminal state.
+- Delete the connector drain from the SIGTERM path. `drainActiveRuns` stays on
+  the controller, where it means "await in-flight runs" — 136 of its 137
+  references carry that meaning and keep working.
+- Fence in-flight manual-upload artifacts by owner epoch instead of the
+  10-minute `MANUAL_UPLOAD_IN_FLIGHT_STALE_MS` wall clock. This requires adding
+  an `owner_epoch` column to `manual_upload_artifacts`, which did not exist.
+- Add an owner-operated repair tool that adjudicates the already-stranded
+  backlog, dry-run by default, with pre-image snapshots taken inside the write
+  transaction.
+
+## Capabilities
+
+### New Capabilities
+
+None.
+
+### Modified Capabilities
+
+- `reference-implementation-architecture`: Define durable controller identity,
+  the successor-adjudicates ownership rule and its newest-epoch exclusion, the
+  single-writer rule for an interrupted run's terminal state, epoch-fenced
+  in-flight artifact sweeps, and the absence of a shutdown-path drain.
+
+## Impact
+
+- `reference-implementation/lib/controller-boot.ts`,
+  `runtime/controller.ts`, `server/index.ts`,
+  `server/stores/manual-upload-artifact-store.ts`,
+  `server/routes/ref-manual-upload-draft-connection.ts`
+- New `controller_identity` table and additive `manual_upload_artifacts.owner_epoch`
+  column on SQLite and PostgreSQL. Both are NULL-tolerant, so existing databases
+  migrate without a backfill.
+- New owner-only repair script
+  `reference-implementation/scripts/repair/adjudicate-orphaned-runs.ts`.
+- Shutdown is faster and its failure mode is honest. Interrupted runs terminalize
+  as `abandoned` at the next boot rather than as `failed` or not at all.
+- Does not change record ingestion, checkpoint commit, or any connector.
+
+## Non-Goals
+
+- **Committing staged cursors under interruption.** The research entry gated
+  this on whether connectors emit bounded `DETAIL_COVERAGE` with
+  `covered == considered` and a non-null boundary. Measured on the live spine,
+  the answer is no: zero of 34,928 `run.detail_coverage_declared` events carry
+  `boundary`, `slice_start`, or `slice_end`. Committing staged cursors under an
+  interrupted terminal state would fabricate denominators, so it is out of scope
+  until that evidence exists.
+- **The checkpoint-contract / interval-claim design.** Out of scope here, and
+  now carried by `qualify-connectors-for-incremental-checkpoint-commit`. An
+  earlier draft of this non-goal described the prototype as not surviving
+  contact with 2 of 3 connectors and therefore "not ready for OpenSpec". That
+  reading is corrected: the contract is a **qualification standard**, and a
+  connector failing it is the qualifier working. `slack` is a genuine
+  disqualifier (no ordered scan at any granularity); `heb` fails at fine
+  granularity but qualifies at day granularity under a closed-day rule. See
+  that change for the verdicts and their evidence.
+- **Any Node version change.**
+- **Auto-resume or auto-retry of interrupted runs.** `chase`, `usaa`, `venmo`,
+  `heb`, `amazon`, and `reddit` need an interactive human sign-in; adjudication
+  is silent by design and lets the normal schedule pick the work up.
+
+## Residual risks
+
+- Owner-authorized live verification remains: after one deploy in a replaced
+  container, a `SIGKILL` mid-run should produce exactly one terminal event for
+  that run and it should be `run.abandoned`. This is live-environment
+  verification, not an implementation task.

+## ADDED Requirements
+
+### Requirement: Every started run SHALL reach exactly one durable terminal state
+
+For every `run.started` event in the spine, either a terminal event SHALL exist
+for that run, or the run's `boot_epoch` SHALL equal the current process's boot
+epoch. The canonical terminal set is `run.completed`, `run.failed`,
+`run.browser_surface_failed`, `run.cancelled`, and `run.abandoned`.
+
+Exactly one component SHALL write a given run's terminal state. A run
+interrupted by process death SHALL be adjudicated by the boot reconciler
+reading the append-only spine. No other reconciler SHALL emit a terminal event
+for an interrupted run, and no component SHALL emit a second terminal event for
+a run that already has one.
+
+Adjudication SHALL be idempotent: each emitted terminal event SHALL carry
+`caused_by_event_id`, and repeated adjudication passes SHALL produce exactly
+one terminal event per orphan.
+
+#### Scenario: A run interrupted by process death is terminalized at the next boot
+
+- **WHEN** a run has a `run.started` event, no terminal event, and a `boot_epoch`
+  that is not the current process's boot epoch
+- **THEN** the boot reconciler SHALL emit exactly one terminal event for that run
+- **AND** the run's `terminal_status` SHALL become non-null
+
+#### Scenario: Repeated adjudication does not duplicate terminal events
+
+- **WHEN** two successive reconcile passes observe the same orphaned run
+- **THEN** exactly one terminal event SHALL exist for that run
+
+#### Scenario: A second writer does not emit a competing terminal event
+
+- **WHEN** a reconciler other than the boot reconciler observes a stale
+  `controller_active_runs` claim for a run
+- **THEN** it SHALL release the stale claim
+- **AND** it SHALL NOT emit any terminal event for that run
+
+### Requirement: An interrupted run SHALL terminalize as abandoned, never as failed
+
+A run whose owner process died without reporting SHALL be recorded as
+`run.abandoned` with reason `controller_terminated_before_run_finished`. It
+SHALL NOT be recorded as `run.failed`, and SHALL NOT be assigned any
+failure reason that asserts an observed failure.
+
+`abandoned` and `failed` SHALL remain distinct terminal states because they
+carry different remedies: `failed` indicates an observed failure that MAY
+require owner attention, while `abandoned` indicates that no owner will ever
+report on the unit and the normal schedule will pick the work up.
+
+Adjudicating an interrupted run SHALL NOT request owner attention, SHALL NOT
+emit an owner notification, and SHALL NOT re-run, re-queue, or retry the work.
+
+Adjudication SHALL NOT delete or edit any existing event, SHALL NOT modify
+ingested records, and SHALL NOT revise `records_emitted`. Records durably
+ingested before the interruption SHALL stay committed.
+
+#### Scenario: An interrupted run with staged cursors is not called a failure
+
+- **WHEN** a run staged a cursor or durably ingested a batch and was then
+  interrupted by process death
+- **THEN** its terminal event SHALL be `run.abandoned`
+- **AND** no `run.failed` event SHALL exist for that run
+
+#### Scenario: Adjudication is silent
+
+- **WHEN** an interrupted run for a connector that requires an interactive human
+  sign-in is adjudicated
+- **THEN** zero owner-attention rows SHALL be created
+- **AND** zero owner notifications SHALL be sent
+- **AND** the run SHALL NOT be automatically retried
+
+#### Scenario: Durable records survive adjudication
+
+- **WHEN** a run is adjudicated as abandoned after durably ingesting records
+- **THEN** those records SHALL remain committed
+- **AND** the run's reported `records_emitted` SHALL NOT be revised
+
+### Requirement: Controller identity SHALL be durable across container replacement
+
+The reference implementation SHALL resolve controller identity from
+`PDPP_CONTROLLER_ID` when set, and otherwise from a durable single-row
+`controller_identity` record stored in the same database that holds the runs.
+The record SHALL be seeded from the host name on the first boot that finds it
+absent, and SHALL be read back unchanged on every later boot.
+
+The host name SHALL NOT be used as the live controller identity. Under a
+container runtime the host name is the container id and is fresh on every
+container creation, which makes an ownership filter keyed on it exclude every
+prior container's orphans.
+
+The boot epoch SHALL continue to advance on every boot. Only the identity is
+stable, so adjudication can still distinguish a prior incarnation's work from
+the current process's work.
+
+An identity that must be supplied by operator configuration SHALL NOT be the
+default, because omitting it fails silently and reopens the ownership defect
+with no signal.
+
+#### Scenario: A replacement container inherits its predecessor's identity
+
+- **WHEN** the reference implementation boots in a new container against a
+  database whose `controller_identity` row already exists
+- **THEN** it SHALL adopt the stored controller id rather than its host name
+- **AND** its ownership filter SHALL select orphans left by the prior container
+
+#### Scenario: First boot seeds the identity
+
+- **WHEN** the reference implementation boots against a database with no
+  `controller_identity` row and no `PDPP_CONTROLLER_ID`
+- **THEN** it SHALL write one row seeded from the host name
+- **AND** every later boot SHALL read that same value back
+
+#### Scenario: The operator override still partitions ownership
+
+- **WHEN** `PDPP_CONTROLLER_ID` is set
+- **THEN** it SHALL take precedence over the stored row
+- **AND** a multi-controller deployment SHALL remain isolated by controller id
+
+### Requirement: A successor SHALL adjudicate only units whose owner epoch is not its own
+
+A unit of work SHALL carry, in the same durable write that starts it, the
+identity of the owner epoch entitled to finish it. A successor epoch SHALL
+adjudicate a unit only when that unit's owner epoch is not the successor's own
+epoch.
+
+A successor SHALL NOT adjudicate any unit belonging to the newest boot epoch.
+A unit started by the process that is still running is live work, not an
+orphan: it lacks a terminal event for the ordinary reason that it has not
+finished. Adjudicating it would declare live work abandoned and free its
+resource for a competing run, reintroducing the duplicate-execution hazard the
+epoch fence exists to prevent.
+
+Eligibility SHALL be decided by epoch comparison, not by an age threshold. A
+unit with a `NULL` owner epoch SHALL be treated as unclaimed and SHALL be
+eligible, since no live process claims it.
+
+An owner-operated repair tool MAY ignore the controller-identity filter, since
+that field is the defect being healed, but SHALL NOT ignore the newest-epoch
+exclusion.
+
+#### Scenario: Live work in the newest epoch is never adjudicated
+
+- **WHEN** an adjudication pass observes a unit whose owner epoch equals the
+  newest `controller.booted` epoch
+- **THEN** it SHALL NOT adjudicate that unit
+- **AND** it SHALL NOT release or reassign that unit's resource
+
+#### Scenario: A prior epoch's unit is adjudicated without a time threshold
+
+- **WHEN** an adjudication pass observes a unit whose owner epoch is neither its
+  own nor the newest epoch
+- **THEN** it SHALL adjudicate that unit regardless of the unit's age
+
+#### Scenario: A unit with no recorded owner epoch is eligible
+
+- **WHEN** an adjudication pass observes an in-flight unit whose owner epoch is
+  `NULL`
+- **THEN** it SHALL treat that unit as unclaimed and eligible for adjudication
+
+### Requirement: In-flight manual-upload artifacts SHALL be swept by owner epoch
+
+The manual-upload artifact store SHALL record the owner epoch of the process
+that created an artifact, written in the same INSERT that creates it. An
+artifact left in an in-flight state SHALL be eligible for sweep when its owner
+epoch is not the current epoch, or when its owner epoch is `NULL`.
+
+Sweep eligibility SHALL NOT be decided by a wall-clock staleness threshold. A
+guessed threshold can be wrong in both directions: it can sweep a slow but live
+validation out from under itself, or leave a genuinely dead upload in place.
+
+An artifact whose owner epoch matches the current epoch SHALL NOT be swept.
+Claiming an artifact for sweep SHALL remain an atomic compare-and-swap and
+SHALL stamp the claiming epoch on a win, so a concurrent second claim loses.
+
+The owner-epoch column SHALL be additive and `NULL`-tolerant on both backends so
+existing databases migrate without a backfill.
+
+#### Scenario: A live in-flight artifact is never swept
+
+- **WHEN** the boot sweep observes an in-flight artifact whose owner epoch is the
+  current epoch
+- **THEN** it SHALL leave that artifact untouched regardless of its age
+
+#### Scenario: An orphaned in-flight artifact is swept immediately
+
+- **WHEN** the boot sweep observes an in-flight artifact whose owner epoch is not
+  the current epoch
+- **THEN** it SHALL claim and sweep that artifact without waiting for any
+  staleness interval
+
+#### Scenario: Legacy artifacts written before the column existed are swept
+
+- **WHEN** the boot sweep observes an in-flight artifact whose owner epoch is
+  `NULL`
+- **THEN** it SHALL treat it as unclaimed and sweep it
+- **AND** the backend predicate SHALL NOT reduce to one that spares `NULL` rows
+
+#### Scenario: Concurrent claims resolve to one winner
+
+- **WHEN** two processes attempt to claim the same in-flight artifact for sweep
+- **THEN** exactly one SHALL win the compare-and-swap and stamp its epoch
+- **AND** the loser SHALL NOT sweep that artifact
+
+### Requirement: Shutdown SHALL NOT attempt to drain in-flight connector runs
+
+The reference implementation SHALL NOT wait for in-flight connector runs on the
+`SIGTERM` path. Interrupted runs SHALL be adjudicated by the successor at the
+next boot instead.
+
+A shutdown drain SHALL NOT be reintroduced as the mechanism for terminalizing
+interrupted work. The container runtime's stop grace period is fixed at
+container creation and is shorter than a connector run, so a drain cannot
+complete the work, and any drain consumes the grace period that remains before
+forced termination. A forced termination receives no shutdown path at all, so a
+design that requires the dying process to write its own terminal state has an
+unhandled case by construction.
+
+Removing the drain SHALL NOT remove the controller's ability to await in-flight
+runs. That capability SHALL remain available to the run watchdog and to
+callers awaiting a specific run.
+
+Resources that outlive an abrupt termination, such as browser profile locks,
+SHALL continue to be reclaimed at the next boot.
+

+## 1. Durable controller identity
+
+- [x] 1.1 Add a `controller_identity` table on SQLite and PostgreSQL holding one
+      row, seeded from `os.hostname()` on the first boot that finds it empty.
+- [x] 1.2 Resolve controller identity as `PDPP_CONTROLLER_ID`, then the durable
+      row, so the hostname survives only as a first-boot seed and never as the
+      live identity.
+- [x] 1.3 Keep the boot epoch advancing per boot, so adjudication still separates
+      "a prior incarnation owned this" from "I own this".
+- [x] 1.4 Add `test/controller-identity-durability.test.ts` proving identity
+      survives a simulated container replacement and that a successor's
+      ownership filter then selects the predecessor's orphans.
+
+## 2. Single writer for an interrupted terminal state
+
+- [x] 2.1 Remove the `run.failed`/`controller_restarted` emission from the
+      controller reconciliation path.
+- [x] 2.2 Retain the stale-claim release as
+      `releaseAbandonedControllerRunClaims`, since
+      `reconcileBrowserSurfaceLeasesAfterBoot` depends on
+      `controller_active_runs` to decide which leases are still held.
+- [x] 2.3 Update `list-active-runs.sql` and `check-run-terminal.sql` and the
+      SQLite/collection-store scheduler drivers for the new terminal vocabulary.
+- [x] 2.4 Update tests to the new contract rather than relaxing them: the restart
+      test asserts `terminal_status === "abandoned"` and that no `run.failed`
+      exists for the run.
+
+## 3. Drop the shutdown drain
+
+- [x] 3.1 Remove the connector drain from the SIGTERM path in `server/index.ts`.
+- [x] 3.2 Verify `drainActiveRuns` itself is retained on the controller and that
+      exactly one reference is removed — 137 references on the base branch, 136
+      after — so the watchdog and `awaitRun` keep working.
+
+## 4. Epoch-fence in-flight manual uploads
+
+- [x] 4.1 Add a NULL-tolerant `owner_epoch` column to `manual_upload_artifacts`
+      on both backends, written in the same INSERT that creates the artifact.
+- [x] 4.2 Replace the `MANUAL_UPLOAD_IN_FLIGHT_STALE_MS` eligibility predicate
+      with the epoch predicate, spelling the NULL arm out explicitly on
+      PostgreSQL so `IS DISTINCT FROM` does not reduce to `IS NOT NULL` and
+      spare the legacy rows.
+- [x] 4.3 Keep the atomic compare-and-swap in `claimForSweep` unchanged in kind,
+      stamping `owner_epoch` on a win so a concurrent second claim loses.
+- [x] 4.4 Update crash-recovery and artifact-store tests on both backends.
+
+## 5. Repair the stranded backlog (operational)
+
+- [x] 5.1 Add `scripts/repair/adjudicate-orphaned-runs.ts` following the sibling
+      repair tools: dry-run by default, `--apply` required to write, full scope
+      printed on every invocation, payload-free output, `--limit` bounding.
+- [x] 5.2 Select orphans without filtering on `controller_id` — that field is
+      what broke — but exclude runs belonging to the newest
+      `controller.booted` epoch so live work is never adjudicated.
+- [x] 5.3 Snapshot the pre-image of every targeted `run.started` event and every
+      re-projected `run_history` row into an `aor_backup` table inside the same
+      transaction as the write.
+- [x] 5.4 Add `test/adjudicate-orphaned-runs.test.ts` covering idempotency,
+      newest-epoch exclusion, and backup completeness.
+- [x] 5.5 Run the dry run against production first and confirm the scope before
+      `--apply`. Verified: dry run reported 121 after the newest-epoch exclusion
+      (123 before it, the two extras being live runs started 90 seconds
+      earlier).
+- [x] 5.6 Apply. Verified on the live instance: backup table
+      `aor_backup_ad8166a2__all__20260821161222` holds 121 spine-event
+      pre-images spanning 2026-05-15 to 2026-07-10 across 106 distinct
+      controller ids, and the orphan predicate now returns 0.
+
+## 6. Validation
+
+- [x] 6.1 Confirm the corrections against the live database rather than the
+      research entry: newest true orphan is 2026-07-10 (the leak is not
+      accruing); `manual_upload_artifacts` had no epoch column; zero of the 134
+      `controller_restarted` runs also received `run.abandoned` (the reconcilers
+      never raced); zero of 34,928 `run.detail_coverage_declared` events carry
+      `boundary`, `slice_start`, or `slice_end`.
+- [ ] 6.2 Run focused controller, controller-boot, manual-upload, and repair-tool
+      suites on both backends, plus typecheck, formatting, and strict OpenSpec
+      validation.
+- [ ] 6.3 Owner-authorized live verification: after one deploy in a replaced
+      container, `SIGKILL` the server mid-run, restart, and assert the run has
+      exactly one terminal event and it is `run.abandoned`, with zero
+      `needs_human` attention rows and zero pushes. This must run the successor
+      in a *new container*, not just a new process — every pre-existing
+      boot-orphan test shared a `controller_id` with the orphan it created,
+      which is what let the defect survive.

+## Why
+
+A run interrupted by a server restart resumes from zero. The owner's standard
+for #166 is "if I restart the server, my data doesn't all go unhealthy"; this
+is the largest remaining gap against it, and it needs a spec change, so it is
+proposed rather than implemented.
+
+`commitState` has exactly two call sites, both inside `handleDoneClose`
+(`runtime/index.ts`). `handleStateMessage` only stages cursors in the
+in-process `newState` map, which dies with the process. **A run that never
+reaches DONE commits no cursor at all, however long it ran.**
+
+Concrete cost. A Slack archive walk takes ~54 minutes. Killed at minute 50, it
+re-fetches all 50 minutes of work on the next run. If deploys land closer
+together than one walk length, such a connection can never finish — it is not
+slow, it is non-converging. 45 runs were ended by restarts between 2026-08-15
+and 2026-08-22 (28 `controller_terminated_before_run_finished` + 17
+`controller_restarted`), concentrated in the longest walks: 9 Slack, 4 Gmail,
+3 YNAB, plus Amazon and Google Maps.
+
+**This is bounded, not catastrophic.** `records` carries a UNIQUE CONSTRAINT
+`records_connector_instance_stream_key (connector_instance_id, stream,
+record_key)`, so ingest is idempotent: a re-walk re-upserts rather than
+duplicating, and no already-collected record is lost. The cost of the current
+rule is **wasted work and staleness, never data loss.** Any change here must
+preserve that property — the current rule is conservative in the right
+direction, and a careless relaxation would trade a real-but-bounded cost for an
+unbounded one.
+
+## The rule today, and why it exists
+
+`spec-collection-profile.md` states it twice, and deliberately:
+
+- Line 151: "The runtime MUST NOT persist STATE checkpoints from a run that
+  terminates in the `failed` state, except for the certified stream-scoped
+  failure described under DONE. State is otherwise persisted only after a
+  successful DONE."
+- Line 497: "A missing or mismatched terminal code, a missing or untargeted
+  skip, an out-of-scope stream, a protocol violation, an invalid terminal count
+  or exit code, **a process exit without valid DONE**, or cancellation MUST
+  preserve the default fail-closed rule and persist no staged STATE."
+
+Line 497 covers a restart directly — a restart *is* a process exit without
+valid DONE. There is no `abandoned` loophole; the case was considered and
+closed. The rule is correct in its purpose: a cursor must not advance past
+records whose detail coverage was never proven. `DETAIL_COVERAGE` is evaluated
+at DONE, and a detail stream may emit coverage for a parent long after that
+parent's own STATE message. Committing a parent early could advance past
+unhydrated detail that no later run would revisit — converting today's honest
+re-fetch into silent data loss.
+
+An implementation attempt confirmed this is load-bearing, not incidental:
+committing at STATE time broke 19 existing tests in
+`test/collection-profile.test.ts`, including the explicit contract "STATE is
+only committed when DONE status is succeeded". It was reverted.
+
+## What Changes
+
+A narrow exception, for a restart only, limited to checkpoints whose coverage
+is already PROVEN at the moment the STATE message is handled.
+
+- Add a terminal disposition for a run ended by controller restart, distinct
+  from `failed`: the run's outcome was never observed, rather than observed to
+  be bad. (This mirrors the distinction already drawn on the read side, where
+  restart-abandoned runs no longer classify connection health.)
+- Permit a runtime to persist a staged checkpoint at STATE time **only when
+  every one of these holds**:
+  1. The checkpoint stream is not named as a detail parent by any in-scope
+     stream's manifest `parent_streams`/`state_stream` declaration — so no
+     DONE-time `DETAIL_COVERAGE` verdict can ever apply to it. This is
+     decidable from the manifest before the run starts, and is exactly the
+     predicate `missingDetailCoverageReports` already uses.
+  2. The records the cursor covers are already durably ingested.
+     `handleStateMessage` already awaits `flushBatch(stateStream)` before
+     staging, so this holds today at that point.
+  3. The connector declared no gap for that stream this run.
+- Keep the fail-closed default for every other case: any stream that could
+  shortfall, any protocol violation, any connector-reported failure, and any
+  owner cancellation continue to persist nothing.
+
+Under this exception a restart-interrupted Slack walk resumes near minute 50
+instead of zero, while a list+detail connector like ChatGPT — whose
+`conversations` checkpoint gates `messages` detail — is unaffected and keeps
+committing only at DONE.
+
+## What this does NOT propose
+
+- No change to the `failed`-run rule. A connector that reports failure still
+  commits nothing beyond the existing certified stream-scoped exception.
+- No change to cancellation. An owner cancel still persists nothing.
+- No weakening of the coverage gate. A stream that could shortfall is excluded
+  by construction, not by a runtime judgement call.
+- No trust in connector self-declaration. Eligibility is derived from the
+  manifest and the runtime's own flush ordering, never from a connector flag —
+  a manifest claim of "safe to commit early" would be voluntary honesty, which
+  this program has been burned by before.
+
+## Alternatives considered
+
+- **Do nothing.** Defensible, because idempotency bounds the cost to wasted
+  work. Rejected as the default answer because a walk longer than the interval
+  between deploys never converges — the owner cannot get a complete Slack
+  archive, which is a data-completeness failure, not a performance one.
+- **Shorten the walks instead.** Real, and worth doing independently, but it
+  does not fix restart-during-walk; it only narrows the window.
+- **Graceful drain on SIGTERM.** Already built, deployed, measured, and
+  removed in `2ddcca1b8` — production logged `drained:0, elapsedMs:5000,
+  timedOut:1`. Docker's stop timeout is 10s and fixed at container creation
+  while real runs take minutes, and a `kill -9` gets no drain at all. Not a
+  viable path; see `design-notes/graceful-drain-verdict-2026-08-22.md`.
+
+## Impact
+
+- Affects `spec-collection-profile.md` (normative), and `runtime/index.ts`
+  `handleStateMessage` once the spec permits it.
+- The eligibility predicate is manifest-derived and computable before the run
+  starts, so conformance is testable offline.
+- Verification should follow D15: kill a run mid-walk, then prove the next run
+  re-fetches nothing before the last committed boundary AND that a
+  detail-parent checkpoint did not advance.
+
+## Owner decision required
+
+The owner gates spec changes. The question is narrow: **may a checkpoint whose
+coverage is already proven survive a restart, when the alternative is that
+long walks never converge?** The safety property that makes this askable is
+that eligibility is decided from the manifest, not from connector claims.

+## MODIFIED Requirements
+
+### Requirement: Checkpoint Persistence Across a Controller Restart
+
+The runtime SHALL continue to fail closed by default: a run that ends in a
+protocol violation, a connector-reported failure, an owner cancellation, or any
+process exit without a valid DONE SHALL persist no staged STATE, except as
+provided below.
+
+As a narrow exception, the runtime MAY persist a staged checkpoint at the time
+its `STATE` message is handled, so that a run interrupted by a controller
+restart resumes from that checkpoint rather than from zero. The runtime SHALL
+apply the exception to a checkpoint stream ONLY when all of the following hold:
+
+1. No in-scope stream declares that checkpoint stream as a detail parent, via
+   the manifest's `state_stream` or `parent_streams` declaration. Eligibility
+   SHALL be derived from the manifest alone and SHALL be decidable before the
+   connector is spawned. The runtime SHALL NOT accept a connector-supplied
+   claim of eligibility.
+2. Every record the cursor covers is already durably ingested at the moment the
+   checkpoint is persisted.
+3. The connector has reported no gap for that stream in the current run.
+
+A checkpoint stream that fails any condition SHALL remain staged and SHALL
+commit only under the existing successful-DONE rule, so that a DONE-time
+`DETAIL_COVERAGE` verdict can never be bypassed.
+
+The runtime SHALL make an eagerly persisted checkpoint distinguishable from one
+that is merely staged, so a reader of the run timeline can tell which
+checkpoints survive a restart.
+
+A run ended by a controller restart SHALL be reported with a terminal
+disposition distinct from `failed`, reflecting that its outcome was never
+observed rather than observed to be bad.
+
+#### Scenario: An interrupted run resumes from its last eligible checkpoint
+
+- **WHEN** a connector emits records for an eligible checkpoint stream, then a
+  `STATE` message for that stream, and the process then exits without a valid
+  DONE
+- **THEN** the runtime SHALL have persisted that stream's cursor durably
+- **AND** the next run SHALL resume from that cursor rather than from zero
+- **AND** the next run SHALL NOT re-fetch records committed before that cursor
+
+#### Scenario: A detail parent's checkpoint never commits early
+
+- **WHEN** an in-scope stream declares a checkpoint stream as its detail parent
+- **AND** the connector emits a `STATE` message for that parent stream
+- **THEN** the runtime SHALL NOT persist that parent's cursor at `STATE` time
+- **AND** the parent's cursor SHALL commit only after a successful DONE whose
+  `DETAIL_COVERAGE` accounting is complete
+
+#### Scenario: Fail-closed defaults are unchanged
+
+- **WHEN** a run terminates with a connector-reported failure, an owner
+  cancellation, an invalid terminal count or exit code, or a protocol violation
+- **THEN** the runtime SHALL persist no staged STATE beyond the existing
+  certified stream-scoped failure exception
+- **AND** an ineligible checkpoint stream SHALL persist nothing in every such
+  case
+
+#### Scenario: Re-collection after a restart cannot duplicate records
+
+- **WHEN** a run interrupted by a restart re-collects a range whose records were
+  already durably ingested
+- **THEN** ingest SHALL upsert on the existing record identity rather than
+  create duplicates
+- **AND** the observable cost of an interrupted run SHALL be repeated work only,
+  never lost or duplicated records

+## 1. Owner decision (blocking)
+
+- [ ] Owner rules on the narrow exception in `proposal.md`. Nothing below starts
+      until the spec change is accepted — the current rule is normative and was
+      deliberately written to cover this case (`spec-collection-profile.md`
+      lines 151 and 497).
+
+## 2. Spec
+
+- [ ] Amend `spec-collection-profile.md` to admit the restart exception, stating
+      the three eligibility conditions and keeping the fail-closed default for
+      every other terminal shape.
+- [ ] Name the restart disposition explicitly in the spec's terminal vocabulary,
+      distinct from `failed` (outcome never observed vs. observed bad).
+
+## 3. Implementation
+
+- [ ] Add the manifest-derived eligibility predicate (a checkpoint stream named
+      as a detail parent by any in-scope stream is ineligible), reusing the same
+      reading of `parent_streams`/`state_stream` that
+      `missingDetailCoverageReports` already applies.
+- [ ] Commit an eligible checkpoint from `handleStateMessage`, after the
+      existing `flushBatch(stateStream)` await.
+- [ ] Report the checkpoint as already-durable in `run.state_staged`, so the
+      timeline distinguishes a checkpoint that survives a restart from one that
+      only survives to DONE.
+- [ ] Leave the DONE-time commit path unchanged for every ineligible stream.
+
+## 4. Tests
+
+- [ ] Prove a connector that emits STATE and then exits WITHOUT DONE leaves its
+      cursor durable — read back over `GET /v1/state/:connectorId`, the same
+      surface the next run reads. Simulate the restart by killing the child
+      after a flushed write; do not use a sleep or any timing proxy.
+- [ ] Prove a detail-parent checkpoint does NOT commit early, so an unproven
+      coverage verdict can never be skipped.
+- [ ] Prove the existing contracts still hold: `DONE(failed)`,
+      `DONE(cancelled)`, and every protocol-violation case in
+      `test/collection-profile.test.ts` still commit nothing.
+- [ ] Mutation-prove each new test in both directions (remove the eager commit;
+      remove the safety predicate). A predicate mutation MUST fail the
+      detail-parent test — an earlier attempt at this work had a safety test
+      that passed with the guard removed, because its fixture manifest was
+      being rejected and the assertion never exercised the path.
+
+## 5. Validation
+
+- [ ] D15 canary: kill a real run mid-walk, then verify the next run re-fetches
+      nothing before the last committed boundary and that no detail-parent
+      cursor advanced.
+- [ ] Confirm idempotency still bounds the failure direction: re-walking an
+      already-committed range re-upserts via
+      `records_connector_instance_stream_key` rather than duplicating.

+## Context
+
+`runRequestedStreams` (`packages/polyfill-connectors/connectors/slack/
+index.ts:2568`) runs the messages/reactions/message_attachments unified pass
+via `runMessagesUnifiedPass`, then declared coverage for all three streams
+before this change. It is called from two places:
+
+1. `collect()`'s main flow (~line 2925), once per run, against the base
+   archive.
+2. `mergeScopedMessageArchivePasses` (~line 1347), inside a `for (const
+   archive of deps.scopedArchives)` loop, once per scoped archive that
+   `reconcileMessageSourceCache` selected to heal a channel missing from the
+   base archive.
+
+Call site 2 only runs when `messageFamilyRequested && isUnscopedMessageBoundary
+&& reconciledSourceCache.scopedArchives.length > 0` (collect(), ~line 2932).
+Production's base archive drops channels over time (export-scope drift,
+workspace membership changes); `reconcileMessageSourceCache` heals each
+missing channel from its own existing scoped archive. Production has always
+needed 3 scoped archives to heal, so call site 2's loop has always run 3
+times per run, each one calling `runRequestedStreams` again on the SAME
+shared `emit`.
+
+`runRequestedStreams`, before this change, emitted DETAIL_COVERAGE for
+`messages` (self-coverage) and for `reactions`/`message_attachments`
+(family coverage, via `declareMessageFamilyCoverage`) unconditionally,
+every time it ran the messages/reactions/message_attachments branch. So one
+base-archive call (site 1) plus 3 scoped-archive calls (site 2's loop) =
+4 emissions of each (state_stream, stream) pair through the same `emit`.
+`reference-implementation/runtime/index.ts:3128`'s `trackDetailCoverage`
+tracks `(state_stream, stream)` pairs it has already seen this run and
+throws `Connector emitted duplicate DETAIL_COVERAGE for
+state_stream=${stateStream} stream=${stream}` on any repeat. Every Slack
+run touching 2+ scoped archives has hit this and failed; 8/8 recorded runs.
+
+## Decisions
+
+### (a) Move the emission out of `runRequestedStreams`, into `collect()`, after the fold
+
+`runRequestedStreams` returns a `MessagesPassResult` (`{ channelMaxTs,
+maxMessageTs, considered }`) whether or not it's the function emitting
+coverage. `mergeMessagesPassResults` (line ~849) already sums `considered`
+across every result it merges — `merged.considered` (or in `collect()`,
+`messageResult.considered` after the merge assignment) is the correct
+summed denominator across the base archive plus every scoped archive
+folded in this run.
+
+The fix: `runRequestedStreams` no longer emits `messages`/`reactions`/
+`message_attachments` DETAIL_COVERAGE at all. `collect()` emits it exactly
+once, unconditionally, via a new `declareMergedMessageCoverage(deps,
+messageResult.considered)` helper, placed after both:
+
+- the base-archive `runRequestedStreams` call, and
+- the conditional `mergeScopedMessageArchivePasses` fold (which reassigns
+  `messageResult` to the folded total when it runs).
+
+`declareMergedMessageCoverage` internally no-ops when the message family
+wasn't requested this run (mirrors the guard `runRequestedStreams` used to
+apply inline), so `collect()` calls it unconditionally rather than adding
+an `if` at the call site — this keeps `collect()`'s branch count from
+growing (it was already at the connector's biome cognitive-complexity
+ceiling).
+
+### (b) Why not gate `runRequestedStreams`'s emission on "am I the last call"
+
+An alternative considered: keep the emission inside `runRequestedStreams`
+but only emit when it's the final call in a fold (e.g. thread an `isLast`
+flag through the loop). Rejected: it requires the loop's caller
+(`mergeScopedMessageArchivePasses`) to know about `runRequestedStreams`'s
+internal emission timing, and it does nothing for the fact that the base
+archive's call (site 1, outside the loop entirely) ALSO emits — the
+base-archive emission and the final scoped-archive emission would still be
+two separate emissions of the same pair. The loop and the base call are two
+independent call sites; the only place that has ever seen the FINAL summed
+`considered` for both is `collect()`, after both have run. Correctness
+requires the emission to live where the merge result is observed, not
+inside either producer.
+
+### (c) Single-archive path is unchanged
+
+When `reconciledSourceCache.scopedArchives.length === 0` (the common case:
+no channel needs healing this run), `mergeScopedMessageArchivePasses` never
+runs and `messageResult` is exactly what the base-archive
+`runRequestedStreams` call returned — the same value the removed inline
+emission used to read. `declareMergedMessageCoverage` still runs exactly
+once, with the same `considered`/`covered` value as before this change.
+This is the case `slack-collection-report.test.ts` and
+`canvases-considered.test.ts`-style unit coverage exercise; the constraint
+is that this change is behavior-invisible on that path.
+
+### Acceptance checks
+
+- 0 scoped archives: exactly one messages/reactions/message_attachments
+  DETAIL_COVERAGE emission, `considered` equal to the base archive's row
+  count — identical to pre-change behavior.
+- 1 scoped archive: pre-fix, `runRequestedStreams` ran twice (base + the one
+  scoped archive), emitting each pair twice — `reference-implementation/
+  runtime/index.ts`'s `trackDetailCoverage` would reject the second
+  occurrence. This was never actually observed failing in
+  `archive-reclaim.test.ts`'s existing single-scoped-archive coverage
+  because that harness (`runConnectorProtocolSubprocess`) spawns the
+  connector standalone and never runs it through the RI runtime process
+  that owns `trackDetailCoverage` — so a duplicate emission there is
+  silently accepted by the test harness, not proof the pair is duplicate
+  -safe in production. Post-fix: exactly one emission per pair, `considered`
+  equal to base + scoped row count.
+- 2+ scoped archives: this is the shape production has always needed (3
+  scoped archives every run) and the shape that has never once completed —
+  pre-fix, N+1 emissions of each pair (base + N scoped archives), and the
+  RI runtime throws on the 2nd. Post-fix: exactly one emission per pair,
+  `considered` equal to the summed row count across base + every scoped
+  archive folded. `scoped-archive-coverage.test.ts` drives the real
+  connector end-to-end (`PDPP_SLACK_SKIP_SLACKDUMP=1`, 2 distinct scoped
+  archives, full messages/reactions/message_attachments scope) and asserts
+  directly on the emitted DETAIL_COVERAGE sequence — this is the
+  regression test for this change.

+## Why
+
+The Slack connector has 8 recorded production runs and 0 successes. Every
+run that folds 2+ scoped archives (`packages/polyfill-connectors/connectors/
+slack/index.ts`, `mergeScopedMessageArchivePasses`, ~line 1364) dies with
+`reference-implementation/runtime/index.ts:3135`'s `Connector emitted
+duplicate DETAIL_COVERAGE for state_stream=messages stream=messages`.
+Production touches 3 scoped archives per run.
+
+`mergeScopedMessageArchivePasses`'s `for (const archive of
+deps.scopedArchives)` loop calls `runRequestedStreams` once per archive.
+Before this change, `runRequestedStreams` itself emitted the messages
+self-coverage `DETAIL_COVERAGE` (`state_stream=messages`, `stream=messages`)
+and the message-family `DETAIL_COVERAGE` (`state_stream=messages`,
+`stream=reactions|message_attachments`, via `declareMessageFamilyCoverage`)
+on every call. With N scoped archives this emitted each (state_stream,
+stream) pair N times through the same `emit` side-channel. `polyfill-runtime`
+already requires a connector emit `DETAIL_COVERAGE` exactly once per run
+(see `openspec/specs/polyfill-runtime/spec.md`, "Connectors with a detail
+lane SHALL emit DETAIL_COVERAGE once per run") — Slack's scoped-archive fold
+violated it.
+
+The summed denominator this emission needs already exists:
+`mergeMessagesPassResults` (line ~849) sums `considered` across archives,
+and the loop's `merged` accumulator (returned at the end of
+`mergeScopedMessageArchivePasses`) carries the correct total. The emission
+was simply happening at the wrong call site — inside the per-archive
+function, instead of once after the fold completes.
+
+## What Changes
+
+- Remove the messages self-coverage and message-family `DETAIL_COVERAGE`
+  emission from inside `runRequestedStreams`.
+- Add a single post-fold emission in `collect()`, using
+  `messageResult.considered` — the value after `mergeScopedMessageArchivePasses`
+  (when it runs) has folded every scoped archive into the base archive's
+  total. When no scoped-archive fold happens (the ordinary single-archive
+  run), `messageResult` is just the base archive's own result, so the
+  emitted value is unchanged from today.
+- No change to `mergeMessagesPassResults`, `mergeScopedMessageArchivePasses`'s
+  fold loop, or the manifest's `state_stream`/`coverage_strategy` declarations
+  for `reactions`/`message_attachments`.
+
+## Capabilities
+
+Modified:
+- `polyfill-runtime`
+
+## Impact
+
+- Affects `packages/polyfill-connectors/connectors/slack/index.ts` only.
+- Fixes every Slack run that touches 2+ scoped archives (the only shape
+  production has ever exercised past the first channel-recovery run) —
+  these have never once completed.
+- No change to the single-scoped-archive or no-scoped-archive cases: same
+  emission count (one), same `considered`/`covered` value as today.

+## MODIFIED Requirements
+
+### Requirement: Connectors with a detail lane SHALL emit DETAIL_COVERAGE once per run
+
+A connector that runs a list+detail lane SHALL emit exactly one `DETAIL_COVERAGE`
+message per run, after the detail lane completes. A list+detail lane is one that
+fetches a list of records and then fetches per-record detail for at least a
+subset of those records. The message SHALL carry:
+
+- `stream`: the detail stream name.
+- `state_stream`: the list/parent stream whose cursor anchors the detail pass.
+- `required_keys`: the full set of record keys the connector considered for
+  detail fetch in this run.
+- `hydrated_keys`: the subset of `required_keys` for which detail was
+  successfully fetched and emitted.
+- `gap_keys` (optional): keys for which a `DETAIL_GAP` was emitted.
+- `optional_skip_keys` (optional): keys skipped by explicit policy (e.g.
+  rate-limited voluntarily, filtered by selection scope).
+
+Connectors that emit only flat streams with no per-record detail fetch are
+exempt from this requirement.
+
+When a connector internally folds multiple independent sources into one
+run's coverage for a `(state_stream, stream)` pair — for example, healing
+missing partitions from separate archives and merging their results — the
+"once per run" requirement applies to the run's single externally observed
+DETAIL_COVERAGE emission for that pair, not to each internal source the
+connector folds. The connector SHALL compute the merged denominator (e.g. a
+summed `considered`) across every source folded, then emit exactly once
+using that merged value. An internal per-source pass SHALL NOT itself emit
+DETAIL_COVERAGE for a pair that the run also emits once, merged.
+
+#### Scenario: list+detail run emits DETAIL_COVERAGE after the detail lane
+
+**WHEN** a connector completes a list+detail run
+**THEN** the connector SHALL emit a `DETAIL_COVERAGE` message
+**AND** the message SHALL appear after the last RECORD or DETAIL_GAP emitted by
+the detail lane in the same run
+**AND** `required_keys` SHALL equal the set of keys the connector scanned for
+detail
+
+#### Scenario: fully hydrated run emits DETAIL_COVERAGE with no gap_keys
+
+**WHEN** a list+detail run completes with no DETAIL_GAP messages
+**THEN** `DETAIL_COVERAGE.hydrated_keys` SHALL equal `DETAIL_COVERAGE.required_keys`
+**AND** `gap_keys` SHALL be absent or empty
+
+#### Scenario: partially hydrated run carries gap_keys matching emitted DETAIL_GAPs
+
+**WHEN** a list+detail run emits N DETAIL_GAP messages
+**THEN** `DETAIL_COVERAGE.gap_keys` SHALL contain those N keys
+**AND** `hydrated_keys` SHALL NOT contain keys that also appear in `gap_keys`
+
+#### Scenario: a run folds multiple internal sources into one coverage pair
+
+**WHEN** a connector's run internally reads from 2 or more independent
+sources (e.g. a base archive plus one or more supplementary archives healing
+missing partitions) that each contribute to the same `(state_stream,
+stream)` DETAIL_COVERAGE pair
+**THEN** the connector SHALL merge each source's contribution into one
+denominator (e.g. summed `considered`) before emitting
+**AND** the connector SHALL emit that `(state_stream, stream)`
+DETAIL_COVERAGE pair exactly once for the run, using the merged denominator
+**AND** no internal per-source pass SHALL emit that pair on its own

+## 1. Reproduction test (write first, before touching the connector)
+
+- [x] Add `packages/polyfill-connectors/connectors/slack/scoped-archive-coverage.test.ts`: seed a base archive missing 2 channels, each recoverable from its own separate pre-existing scoped archive, drive the real connector via `runConnectorProtocolSubprocess` (`PDPP_SLACK_SKIP_SLACKDUMP=1`) with `messages`/`reactions`/`message_attachments` in scope, and assert each `(state_stream, stream)` DETAIL_COVERAGE pair appears exactly once with the summed `considered`.
+- [x] Confirm the test fails against unmodified `connectors/slack/index.ts` (3 emissions of the `messages` pair: base + 2 scoped archives), then leave it in the suite.
+
+## 2. Fix
+
+- [x] Remove the messages self-coverage and message-family DETAIL_COVERAGE emission from inside `runRequestedStreams`.
+- [x] Add `declareMergedMessageCoverage(deps, considered)`, gated internally on the message family being requested (mirrors the removed inline guard), emitting the self-coverage then delegating to the existing `declareMessageFamilyCoverage`.
+- [x] Call `declareMergedMessageCoverage` once from `collect()`, after both the base-archive `runRequestedStreams` call and the conditional `mergeScopedMessageArchivePasses` fold, using the (possibly folded) `messageResult.considered`.
+
+## 3. Existing test repair
+
+- [x] Update `integration.test.ts`'s `"runRequestedStreams: archive message enumeration bounds both derived streams"` test, which asserted DETAIL_COVERAGE emission from inside `runRequestedStreams` directly — that emission moved to the caller, so assert on the returned `MessagesPassResult.considered` instead, and assert no DETAIL_COVERAGE is emitted from this call in isolation.
+
+## 4. Validation
+
+- [x] Run the new test; confirm GREEN with the fix applied.
+- [x] Run the full `connectors/slack/**/*.test.ts` suite; confirm no regressions (201/201 pass).
+- [x] Run `reference-implementation`'s `test/slack-collection-report.test.ts` (unaffected — projection layer, not connector).
+- [x] `npm --prefix reference-implementation run typecheck` — clean.
+- [x] `npm --prefix packages/polyfill-connectors run typecheck` — clean.
+- [x] `npx biome check` on every changed file — clean (required extracting `declareMergedMessageCoverage` and gating the message-family check inside it, rather than an `if` in `collect()`, to stay under the cognitive-complexity ceiling).
+- [x] `openspec validate fix-slack-scoped-archive-coverage-duplication --strict` — passes.

+## Context
+
+The coverage snapshot answers one question: did the collector account for
+everything the server requires? The previous gate also failed when the collector
+accounted for something the server no longer asks about, which is a different
+question and not one that bears on completeness.
+
+## Decision: the missing/unexpected asymmetry is the whole change
+
+**Unexpected is not fatal.** A collector reporting a store this build no longer
+declares scanned *more* than was asked of it. That cannot weaken a completeness
+claim. The parser already excludes unexpected entries from `rows` — it
+`continue`s before pushing — so they cannot corrupt the proof either. Their only
+effect was to fail the gate.
+
+**Missing stays fatal.** A missing store means the collector did not account for
+something the server requires. The snapshot genuinely is not committed, and
+saying otherwise would be the dishonesty this codebase is trying to remove.
+
+**Duplicate and malformed stay fatal.** Both indicate a report that cannot be
+trusted to mean what it says, which is distinct from a report that means more
+than needed.
+
+## Why not fix the device instead
+
+Updating the collector on the affected device resolves this instance and leaves
+the class untouched. Any user whose device and server versions ever diverge —
+which is every user eventually — hits the same wall, and the failure presents as
+"Not measured" with no diagnostic naming the drift. The lenient gate fixes the
+class and fixes this instance without touching the device.
+
+## Prior art
+
+restic exits `0` on full success and `3` on "some source files could not be
+read" — an incomplete-but-usable snapshot is still created. borg distinguishes
+`0` success, `1` warning, `2` error. rclone's `check` reports `--missing-on-dst`,
+`--differ` and `--match` as separate named categories. None discards a result
+because it is imperfect in one direction; partial coverage is a tagged status on
+still-valid data.
+
+## Acceptance
+
+- Every expected store present plus one unexpected store: snapshot commits,
+  `unexpectedStores` still reports the drift, the unexpected entry never appears
+  in `rows`.
+- A missing required store: snapshot does not commit.
+- A duplicate store: snapshot does not commit.
+- A malformed entry: snapshot does not commit.

+## Why
+
+`packages/polyfill-connectors/src/local-source-inventory.ts` treated an
+unexpected store as fatal to a coverage snapshot:
+
+```ts
+const hasCommittedSnapshot =
+  !malformed && duplicateStores.length === 0 &&
+  unexpectedStores.length === 0 && missingStores.length === 0;
+```
+
+An unexpected store is one the collector reported that the server's descriptor
+table no longer declares — the normal result of a device running a build older
+than the server. One such name set `hasCommittedSnapshot = false`, then
+`reliable = false`, then coverage axis `unknown`, rendered as "Not measured".
+
+Measured on production: connection `cin_ece4bfe5096b8bf67a1468c2` ("peregrine
+Codex") has **1,293,596 collected records**, summary evidence `state=fresh` with
+every component `current`, a current heartbeat and a drained outbox — and
+displays "Not measured". The only drift is a single legacy `logs` store. Nothing
+is missing: every declared store is reported.
+
+## What Changes
+
+- An unexpected store no longer disqualifies a coverage snapshot.
+- `unexpectedStores` is still returned, so the drift stays observable — it
+  becomes informational rather than disqualifying.
+- Missing, duplicate, and malformed remain fatal, unchanged.

+## Context
+
+The vocabulary for run lifecycle already exists and is mostly correct. What is
+missing is an owner. `run.abandoned` is a first-class terminal event in
+`check-run-terminal.sql` and `run-history-writer.ts`; `run_generation` is a
+textbook Kleppmann fencing token; `finalizeRunCleanup` implements a correct
+compare-and-swap. Each is right on its own. None of them is *the* authority,
+so each had to be invented where it was needed, and the copies drift.
+
+This design is therefore about consolidation, not invention. The states are
+already implied by the terminal set; the transitions are already implied by the
+guards; the fence already ships in `controller_identity`. The work is to state
+them once, in one module, with the database — not a comment — enforcing them.
+
+Every claim below cites code read on `fix/sweep-fairness-and-transformer-bounds`
+at `39d19704a`. Where the brief's figures did not reproduce, the measured value
+is given and the discrepancy is named.
+
+## Goals / Non-Goals
+
+**Goals:**
+
+- One closed state set, declared once, that every consumer reads.
+- One writer per transition, named in the table.
+- Every durable transition is a compare-and-swap fenced by owner epoch, failing
+  at the database rather than by convention.
+- Every historical incident cluster is expressible as an illegal transition, or
+  is recorded as a finding explaining why it is not.
+- Property tests that fail before implementation and pass after.
+
+**Non-Goals:**
+
+- Scheduling policy of any kind (D4's guard).
+- A generic "workflow engine." Six boot reconcilers should share a predicate,
+  not an executor — the sibling change already ruled on this and it holds here.
+- Changing observable connector behavior. This is a refactor of truth-keeping
+  (D14).
+
+## (a) The closed state set
+
+Nine states. `run_history.status` is the durable projection of this set, and
+its existing literals map one-to-one — the set is not new vocabulary, it is the
+existing vocabulary closed and named.
+
+| State | Terminal | Durable projection | Meaning |
+|---|---|---|---|
+| `pending` | no | `run_history.status='pending'` | Admitted by the executor, not yet started. Exists so admission has a durable pre-state to CAS against. |
+| `running` | no | `status='running'` | `run.started` emitted; the owning epoch is executing. |
+| `awaiting_interaction` | no | `status='running'` + derived | The connector asked the owner for input and is blocked. Today derived in SQL by `controller-boot.ts:374-387`. |
+| `cancel_requested` | no | `status='running'` + derived | `run.cancel_requested` seen; the executor has not yet stopped. |
+| `succeeded` | **yes** | `status='succeeded'` | `run.completed`. |
+| `failed` | **yes** | `status='failed'` | `run.failed`. An observed failure. |
+| `surface_failed` | **yes** | `status='surface_failed'` | `run.browser_surface_failed`. Terminal pre-launch. |
+| `cancelled` | **yes** | `status='cancelled'` | `run.cancelled`. Owner-initiated. |
+| `abandoned` | **yes** | `status='abandoned'` | `run.abandoned`. No owner will ever report. Distinct from `failed` per the landed owner-epoch change. |
+
+`pending` is the one addition. Everything else already exists as a
+`toTerminalStatus` output (`run-history-writer.ts:91-108`) or a `status`
+literal. `awaiting_interaction` and `cancel_requested` are named here because
+the machine must be able to *refuse* transitions out of them; they project onto
+`running` so no reader changes.
+
+`skipped` is deliberately **not** a run state. It is written to
+`run_history.status` by the scheduler's pre-run gate
+(`scheduler/pre-run-gate.ts:99,119,141,157,173,193`) and by
+`scheduler/run-executor.ts:555,572,592` for attempts that never started a run.
+A skipped attempt has no `run.started` event and no run to transition — it is a
+*dispatch outcome*, which is planner territory under D4. Recording it in the
+same column as run state is how "scheduler-generated `status:"skipped"` records
+fed into health classification" (the Gmail identity self-poisoning loop) became
+possible. The machine does not adopt it; the migration keeps it writable by the
+planner and forbids the machine from reading it as a run state.
+
+**The set SHALL be declared once.** Today the terminal event set is declared in
+at least **thirteen** places and **six of them disagree**. `lib/spine.ts:1066`
+claims authority in its own comment — "All run-status projection code must read
+from this set; never hardcode subset checks" — and is then not read by the
+divergent copies:
+
+| Declaration | Contents | Verdict |
+|---|---|---|
+| `lib/spine.ts:1066` (claims canonical) | 5 | correct |
+| `stores/run-history-writer.ts:60`, `stores/connector-attention-store.ts:50`, `scripts/repair/adjudicate-orphaned-runs.ts:123`, `controller-boot.ts:707`, `queries/spine/check-run-terminal.sql:15`, `queries/spine/get-run-terminal-event.sql:13`, `db.ts:5992` | 5 | correct |
+| `connector-summary-read-model.ts:1253` | **4 — omits `run.abandoned`** | **defect** |
+| `db.ts:5437` `SPINE_TERMINAL_EVENT_TYPES_SQL` | **4 — omits `run.abandoned`** | **defect** |
+| `postgres-storage.ts:2692,2716,2744,2793` | **4 — omits `run.abandoned`** | **defect** |
+| `connector-summary-evidence-engine.ts:1599,1799` | **4 — omits `run.abandoned`** | **defect** |
+| `lib/postgres-spine.ts:570` | **4 — omits `run.browser_surface_failed`** | **defect** |
+| `postgres-storage.ts:2336` | **4 — omits `run.browser_surface_failed`** | **defect** |
+
+`db.ts:5433` states it is "kept in sync with" `connector-summary-read-model.ts`.
+The two agree with each other and both disagree with `lib/spine.ts`. The
+observable consequence: an abandoned run is invisible to the connector-summary
+fold and to the `connector_instance_id` backfill the fold's partial index
+serves. The 121 runs adjudicated by the sibling change are exactly the
+population this omission hides. Separately, four PostgreSQL-side declarations
+omit a *different* member than the SQLite-side ones, so the two backends
+disagree about what "terminal" means — cluster 4's defect class, in the
+terminal vocabulary itself.
+
+A comment asking two constants to stay in sync is not a mechanism. This is the
+completeness test for D3 working as intended: writing the state set down found
+six live divergences that no test catches.
+
+### Audit: every side-state that lives beside run state
+
+Verdicts are **absorb** (becomes a real state), **derive** (computed from the
+machine, never stored), or **delete**.
+
+| Side-state | Location | Verdict | Rationale |
+|---|---|---|---|
+| `activeRuns` map | `controller.ts:981` | **derive** | Currently the real admission authority; `finalizeRunCleanup:3249` hand-rolls a CAS on it. Becomes a read-through cache of `state ∈ {pending, running}` fenced by epoch. Its correctness stops depending on process memory. |
+| `activeRunPromises` | `controller.ts:986` | **keep, out of scope** | Holds a JS promise, not state. "Await this run" is a runtime affordance with no durable meaning. Not a second truth. |
+| `settledRunIds` | `controller.ts:997` | **delete** | Exists only to answer "did finalize already run?" — which `state` in a terminal set answers exactly. The `isStale` probe at `:3312` becomes a state read. |
+| `controller_active_runs` | `db.ts:1149`, `postgres-storage.ts:1945` | **absorb** | The durable flight table. Becomes the `pending`/`running` rows of the machine rather than a parallel table. `reconcileBrowserSurfaceLeasesAfterBoot` reads it and keeps working — it is being re-homed, not removed. |
+| `run_generation` | `db.ts:1156`, `controller.ts:1046` | **absorb → replaced by `owner_epoch`** | A per-instance monotonic fencing token, correct in kind but reinvented and *in-process* (`runGenerations` Map, cleared only by test reset). The owner epoch is the same idea already durable in `controller_identity`. One fence, not two. Note: the run-generation column shipped to SQLite before Postgres once — the exact dual-backend gap this design forbids. |
+| `runWatchdogSettlements` | `controller.ts:1031` | **derive** | Watchdog fires ⇒ attempt an `abandoned` transition. If the CAS loses, the run already terminalized. Removes the timer/completion race entirely. |
+| `needsHumanAttention` | `controller.ts:1055` | **delete (not absorb)** | In-memory `Set`, lost on restart, and **not a run state** — it is a per-*connection* automation-suppression policy. Absorbing it would smuggle scheduling policy into the machine, violating D4. It moves to the scheduler's own policy input, derived from terminal runs whose reason is an unresolved interaction. |
+| `cooling_off` / `blocked` | `scheduler-backoff.ts:252` | **delete from run state** | Already not run state — a `recommendedHealthState` derived from a failure streak. Named here to record it as correctly-placed policy, and to forbid it moving in. |
+| `scheduler_dispatch_wedged` | `scheduler.ts:197-215` | **derive** | A synthetic `status:"failed"` `RunRecord` fabricated when the pre-launch gate misses its liveness ceiling. Under the machine this is a real `failed` transition with `terminal_reason='scheduler_dispatch_wedged'`, not a fabricated record. The word "wedged" survives as a reason, not a shadow state. |
+| `run_history.status` | `db.ts:1365` | **absorb** | The durable projection. Gains `owner_epoch` (below). |
+| `scheduler_managed` | `db.ts:1379` | **keep, out of scope** | Provenance, not lifecycle. Marks which writer touched the row; scheduler cadence readers filter on it. Orthogonal. |
+| `manual_upload_artifacts.owner_epoch` | landed sibling | **precedent** | Not run state. Cited because it is the pattern this design generalizes: an epoch column that replaced a wall clock. |
+
+### F1 cluster completeness (D3's test)
+
+| Cluster | Expressible as illegal transition? |
+|---|---|
+| GroupMe 503 — dispatch probe vs. active run | **Yes.** Planner attempting any write while `state ∈ {pending, running}`. Forbidden transition F1 below. |
+| Ingest 503 never retried (Aug recurrence) | **Yes**, partially. The batch-level retry is HTTP policy, but the *observable* defect — a run reporting `failed` while records were durably committed — is `running → failed` attempted by a non-owner. Forbidden F5. |
+| YNAB stuck-run wedge (`activeRuns` leak) | **Yes.** A run with no live owner epoch stuck non-terminal; `abandoned` becomes reachable, so the 409 cannot be permanent. Forbidden F6. |
+| Collector-runner drain boundary race | **Yes.** Two clock reads with opposite boundary semantics; under CAS the second read cannot act on the first read's stale premise. Forbidden F3. |
+| Run-generation fencing / stale controller write | **Yes.** Precisely the epoch CAS. Forbidden F2. |
+| Controller-restart misclassification (`failed` vs `abandoned`) | **Yes.** `running → failed` by the boot path is forbidden; only `running → abandoned` is legal there. Forbidden F4. |
+| **Maintenance-sweep shared-deadline starvation (×3)** | **NO — reported as a finding.** |
+
+**The cluster that does not fit.** The maintenance-sweep starvation family
+(2026-08-01 ×2, 2026-08-03) is not a run-lifecycle defect. No illegal run
+transition occurs: every run in those incidents was in a legal state the whole
+time. The defect is that a *shared budget* was divided unfairly across
+page-mates, so some connections never got serviced. Forcing it into this table
+would require modelling scheduler fairness as run state — which is exactly the
+policy-in-the-machine error D4 forbids. Recording it as out of scope is the
+honest answer, and it belongs to the sweep-fairness work already in flight on
+this very branch. The state set is not missing a state on its account.
+
+## (b) The legal transition table
+
+**Single writer per transition.** "Executor" means the one owner module this
+design mandates; today its responsibilities are split across `runtime/index.ts`,
+`runtime/controller.ts`, and `runtime/scheduler/run-executor.ts`.
+
+| # | Transition | Precondition | Single writer |
+|---|---|---|---|
+| T1 | `∅ → pending` | No non-terminal run for this `connector_instance_id` | Executor (admission) |
+| T2 | `pending → running` | Caller holds the current owner epoch; `run.started` emitted | Executor |
+| T3 | `running → awaiting_interaction` | Connector emitted `run.interaction_required` / `run.assistance_requested` | Executor |
+| T4 | `awaiting_interaction → running` | Interaction reached a terminal interaction event | Executor |
+| T5 | `running → cancel_requested` | Owner requested cancel (`run.cancel_requested`) | Executor, on owner intent |
+| T6 | `running → succeeded` | Connector reported DONE; terminal commit gate passed | Executor |
+| T7 | `running → failed` | Observed failure attributable to this run | Executor |
+| T8 | `running → surface_failed` | Browser surface failed pre-launch | Executor |
+| T9 | `cancel_requested → cancelled` | Executor observed the request and stopped | Executor |
+| T10 | `{pending, running, awaiting_interaction, cancel_requested} → abandoned` | Run's `owner_epoch` is neither the actor's nor the newest boot epoch | **Boot adjudicator** (the sole exception to "executor only"; see (f)) |
+| T11 | `awaiting_interaction → abandoned` | As T10, with reason `controller_terminated_while_awaiting_owner_interaction` | Boot adjudicator |
+
+Terminal states have no outgoing transitions. That is the whole point of the
+set being closed.
+
+### Forbidden transitions, each naming the incident it prevents
+
+| # | Forbidden | Incident prevented |
+|---|---|---|
+| F1 | Any run-state write by the **planner/scheduler** | **GroupMe 503.** `dispatchIfDue` probed `getForwardEvidenceDebt`'s reconcile write against an instance with a run in flight, contending on the per-instance mutex and turning committed batches into `connector_instance_busy` failures. Fixed at `scheduler.ts:636` by a guard whose own comment says it mirrors "the guard `executeRun` already applies one step later" — one rule stated twice. Under F1 the planner has no write path to guard. |
+| F2 | Any transition whose actor's epoch ≠ the run's `owner_epoch` | **Stale-controller writes / run-generation fencing.** A predecessor that resumes after a successor took over must lose *at the database*. Today `run_history` has no epoch column, so this is enforced only in process memory (`controller.ts:1046`). |
+| F3 | Any transition whose observed `state` ≠ the CAS expected state | **Collector-runner drain boundary race.** Two clock reads with opposite boundary semantics (`<=` on claim, `>` on `nextRetryTime`) let a deadline landing between them produce a false "empty" exit. A CAS cannot act on a premise that changed under it. |
+| F4 | `{pending, running, …} → failed` by the boot/adjudication path | **Controller-restart misclassification.** 134 production runs recorded `run.failed`/`controller_restarted`; 55 had staged a cursor and 34 had durably ingested a batch. Interruption is not observed failure. Only T10/T11 are legal there. |
+| F5 | A second terminal transition on an already-terminal run | **Double-terminal / ingest-503 misreporting.** The existing `AND status='running'` fence (`run-history-writer.ts:355`) already provides this for `run_history`; F5 makes it a property of the machine rather than of each writer remembering to add it. |
+| F6 | A run remaining non-terminal with no live owner epoch | **YNAB stuck-run wedge.** A hung subprocess left an `activeRuns` entry forever, 409-ing every future manual run until restart. `abandoned` must always be reachable, so "wedged forever" is unrepresentable. |
+| F7 | Any transition out of a terminal state | Terminal means terminal. Makes `records_emitted` revision-after-terminal — explicitly forbidden by the landed change — structurally impossible. |
+| F8 | Any write to run state not routed through the owner module | **D1.** A `transitionRun()` helper that five modules import is today's distributed writes wearing a uniform. Raw `INSERT`s into `spine_events` (`controller-boot.ts:526`, `:597`) are the current instance of this. |
+
+### Three live defects the table would have prevented
+
+Found while auditing writers. Each is a real, current divergence — reported as
+findings, not fixed here.
+
+1. **An unfenced upsert can overwrite a terminal status.**
+   `queries/controller/insert-run-history.sql:40` and its PostgreSQL twin
+   `stores/scheduler-store.ts:1018` are `ON CONFLICT (run_id,
+   connector_instance_id) DO UPDATE SET status = excluded.status` with **no
+   `status = 'running'` fence**. Every other status writer has one
+   (`run-history-writer.ts:355`, `:406`; `controller-boot.ts:670`, `:791`,
+   `:859`). The scheduler's `appendRunHistory` normally runs *after* the generic
+   writer has already finalized the row, so a scheduler retry can revise an
+   already-terminal outcome. This is forbidden transition **F5** and **F7**,
+   both violated by one statement.
+2. **The PostgreSQL drift repair fences on `run_id` alone.**
+   `controller-boot.ts:829` joins `WHERE h.run_id = t.run_id AND h.status =
+   'running' AND h.connector_instance_id IS NOT NULL` — an `IS NOT NULL` check,
+   not an equality. Its SQLite twin at `:788-790` correctly fences
+   `AND connector_instance_id = ?`. The codebase documents in several places
+   that `run_id` is not unique across connections, which is why every other
+   writer fences on the pair. A dual-backend asymmetry in the repair path
+   itself — cluster 4's defect class, inside the adjudication code.
+3. **`run_generation` is written from two incompatible sources.**
+   `controller.ts:3139-3187` derives it from a monotonic per-instance counter;
+   `scheduler/run-executor.ts:819` sets it from `attempt`, a retry counter.
+   One column, two meanings. Absorbing the fence into `owner_epoch` (M5)
+   retires the ambiguity rather than arbitrating it.
+
+4. **Two `createReferenceSchedulerManager` definitions exist.** One is inline
+   at `server/index.ts:8828` and is what production calls (`:8378`). The other
+   is exported from `server/scheduler-manager-factory.ts:374`, carries its own
+   copy of all four dispatch probes — including the same
+   `reconcileDirtyConnectorSummaryEvidence` write at `:558` — and is imported
+   by **nothing outside tests**; the two importing tests take only
+   `createRunManagedConnectorViaController`. A parallel copy of the exact
+   subsystem this design governs, whose divergence no test can see. M2 must
+   pick one before cutting writers over. This is D5's masking-pair hazard
+   sitting in the tree already.
+
+A fifth observation, not a defect: **`drainActiveRuns` has no production
+caller.** All 116 call sites are test teardown. Its own doc comments
+(`controller.ts:987`, `server/index.ts:8567`) still describe it as the
+graceful-shutdown path and are stale relative to `server/index.ts:9670-9691`.
+See the migration section for the full verdict.
+
+## (c) The CAS + owner-epoch schema
+
+### Schema change
+
+`run_history` gains one column on both backends, NULL-tolerant so existing rows
+migrate without a backfill:
+
+- SQLite (`server/db.ts`): `owner_epoch TEXT` via the existing
+  `addColumnIfMissing` helper — the same mechanism `run_generation` used at
+  `db.ts:6171`.
+- PostgreSQL (`server/postgres-storage.ts`):
+  `ALTER TABLE run_history ADD COLUMN IF NOT EXISTS owner_epoch TEXT;` — the
+  same shape used for `controller_active_runs.run_generation` at
+  `postgres-storage.ts:1960`.
+
+Verified absent today: `db.ts:1358-1395` and `postgres-storage.ts:2169-2197`
+list every column, and neither has an epoch. The epoch exists only inside the
+spine event's `data_json` (`runtime/index.ts:2745-2749`), which no `UPDATE` can
+fence on cheaply. **Both backends in the same change** — `run_generation`
+shipped to SQLite without Postgres once and was caught only as a deploy
+blocker; the landed owner-epoch change repeats the warning. This design treats
+a single-backend schema change as a defect by construction.
+
+The epoch value is the boot epoch already stashed by
+`emitControllerBootedAndStashEpoch` (`controller-boot.ts:202-231`), whose
+identity half is durable in `controller_identity` (`controller-boot.ts:96-151`,
+one row `id='singleton'`, live in production and verified by reading the file).
+
+### The predicate
+
+Every durable transition is one statement. No read-then-write.
+
+**SQLite** (`better-sqlite3`, synchronous; decide by `.changes`):
+
+```sql
+UPDATE run_history
+   SET status = ?,            -- new state
+       completed_at = ?,      -- terminal transitions only
+       terminal_reason = ?
+ WHERE run_id = ?
+   AND connector_instance_id = ?      -- run_id alone is not unique
+   AND status = ?                     -- expected state
+   AND (owner_epoch = ? OR owner_epoch IS NULL);
+```
+
+**PostgreSQL** (decide by `rowCount`):
+
+```sql
+UPDATE run_history
+   SET status = $1,
+       completed_at = $2,
+       terminal_reason = $3
+ WHERE run_id = $4
+   AND connector_instance_id = $5
+   AND status = $6
+   AND (owner_epoch = $7 OR owner_epoch IS NULL);
+```
+
+Four properties of this predicate are load-bearing:
+
+1. **`changes`/`rowCount` = 0 means the transition was refused**, and the caller
+   must treat that as an ordinary outcome — someone else already moved the run.
+   It is never retried blindly and never escalated to the owner.
+2. **`connector_instance_id` is part of the fence, not decoration.** `run_id`
+   alone is not unique across connections; both `run-history-writer.ts:355` and
+   `controller-boot.ts:670` already fence on the pair, and this preserves that.
+3. **The NULL arm is spelled out explicitly, not written `IS DISTINCT FROM`.**
+   The landed sibling change was bitten by exactly this: on PostgreSQL,
+   `owner_epoch IS DISTINCT FROM NULL` reduces to `owner_epoch IS NOT NULL` and
+   would spare precisely the legacy rows that most need claiming. Writing
+   `(owner_epoch = $7 OR owner_epoch IS NULL)` is identical on both backends
+   and cannot silently reduce.
+4. **The NULL arm is `OR`, not `AND`.** A legacy row written before the column
+   existed has no claimant, so any epoch may adjudicate it. A row *with* a
+   different epoch may not.
+
+The adjudication transition (T10/T11) inverts arm 4 — it must match rows whose
+epoch is *not* the actor's — and additionally excludes the newest boot epoch, so
+live work is never adjudicated:
+
+```sql
+   AND (owner_epoch IS NULL OR owner_epoch <> :mine)
+   AND (owner_epoch IS NULL OR owner_epoch <> :newest_boot_epoch)
+```
+
+This is the predicate the landed change already proved against production: its
+dry run reported 123 before the newest-epoch exclusion and 121 after, the two
+extras being runs a live container had started ninety seconds earlier.
+
+### Why CAS and not a lock
+
+An advisory lock answers "may I proceed?" at a moment; a CAS answers "was the
+world still as I assumed when I wrote?" — which is the actual question after an
+`await`. This repo already has at least five independently-invented admission
+mechanisms (F1's count), and adding a sixth lock would extend that list. The CAS
+adds no new mechanism: it is a `WHERE` clause on writes that already happen.
+
+## (d) Property-test skeletons
+
+Listed in `tasks.md` §5 with file names. Each is `.todo` or asserts against the
+not-yet-existing owner module, so **none can pass before implementation**. That
+is the requirement: this program has already shipped a conformance test that
+asserted behavior it never exercised, and a guard that cannot fail certifies a
+regression as safe.
+
+Each skeleton names its property, its generator, and its invariant, and each
+maps to a row in the forbidden table above. Dual-backend skeletons run against
+SQLite and PostgreSQL from one body, because a Postgres-only divergence is
+invisible to this suite by construction — that is a named defect class here
+(6,792 tests stayed green while production could not paginate).
+
+## (e) The D4 split, stated precisely
+
+- The **planner** (`runtime/scheduler.ts`, `scheduler/dispatch-governor.ts`,
+  `scheduler-backoff.ts`) READS run state and emits **intents**. It writes no
+  run state, ever.
+- The **executor** is the sole writer of transitions T1-T9, and the boot
+  adjudicator of T10-T11.
+
+**The split does not hold today.** A first pass suggested it nearly did —
+`runtime/scheduler.ts` emits no spine event and contains no literal `UPDATE
+run_history`. That reading was wrong, and the correction matters more than the
+original claim. The scheduler writes run state four ways:
+
+| # | Write | Site |
+|---|---|---|
+| P1 | `INSERT INTO run_history` for skip and back-off records | `scheduler.ts:432`, `:445` (`recordAndNotify` → `schedulerStore.appendRunHistory`), called from `dispatchIfDue:655`, `:662`; SQL at `scheduler-store.ts:570` / `:995` |
+| P2 | `scheduler_last_run_times` upsert | `scheduler.ts:477`; `scheduler-store.ts:1607` |
+| P3 | In-process `activeRuns` set and five announcement-dedup maps | `scheduler.ts:547`, `:576`; `dispatch-governor.ts:559`, `:563`, `:588`, `:590`, `:593` |
+| P4 | **A durable repair write inside the dispatch-eligibility probe** | `server/index.ts:9057` — `getForwardEvidenceDebt` calls `reconcileDirtyConnectorSummaryEvidence([instanceId])` *before* its read at `:9058`; that reconcile takes `withConnectorInstanceWrite` and issues `withPostgresTransaction({ lockConnectorInstanceId })` upserts (`connector-summary-evidence-engine.ts:1281`, `:1866`, `:2691`) |
+
+**P4 is the GroupMe 503 mechanism**, and it is the clearest violation of D4:
+a read-only-looking eligibility probe that takes the per-instance write mutex.
+So F1 must forbid *side-effecting reads*, not merely direct writes. A planner
+that "only reads" but whose read reconciles is a writer.
+
+P1 is the second-order version of the same error: the scheduler writes rows
+that feed back into `runtime.history`, which is the next tick's own decision
+input. The Gmail identity self-poisoning loop is exactly this — scheduler-
+generated `status:"skipped"` records read back as run outcomes.
+
+Under this design: P4 moves to the executor or becomes genuinely read-only.
+P1's records stay writable by the planner but are not run states (see
+`skipped`, above) and the machine never reads them. P2 is planner-owned cadence
+state, unaffected. P3's `activeRuns` set is replaced by an epoch-fenced read of
+the machine — today it is an in-process `Set` that dies with the process, so
+the `dispatchIfDue` guard does not suppress a probe against a run started by a
+different process or surviving a restart.
+
+**The policy guard.** The machine answers *is this transition legal*. It never
+answers *which connector runs next*. Concretely: `cooling_off`, `blocked`,
+backoff curves, fairness rotation, admission deadlines, and per-statement
+budgets stay in the planner. "Runnable" means "no legal impediment to a T1"; it
+does not mean "chosen." `needsHumanAttention` is deleted from the controller
+for exactly this reason — it reads like run state and is actually automation
+policy.
+
+## (f) The D6 formalization
+
+`scripts/repair/adjudicate-orphaned-runs.ts` and
+`reconcileOrphanedRunsAtBoot` (`controller-boot.ts:344`) implement the same
+adjudication with different scopes. The script is the owner-operated backlog
+tool: dry-run by default, ignores `controller_id` (the field that was broken),
+excludes the newest boot epoch, snapshots pre-images into an `aor_backup` table
+inside the write transaction. The boot reconciler is the steady-state path:
+filters on `controller_id`, runs before HTTP routes mount, aborts boot on error.
+
+Under this design the boot reconciler **is** transitions T10/T11 — the same
+predicate, expressed once in the owner module. Three properties must be
+preserved exactly, because this is a behavior-preserving move (D14):
+
+1. **Idempotency stays on `caused_by_event_id`,** via the
+   `spine_run_abandoned_cause_unique` partial index. Repeated passes emit
+   exactly one terminal event per orphan. The existing code catches *only* the
+   named constraint and never blanket-catches `23505` / `SQLITE_CONSTRAINT_UNIQUE`;
+   the owner module must keep that discipline.
+2. **Newest-epoch exclusion stays,** and stays load-bearing. Without it,
+   adjudication declares live work abandoned and frees its resource for a
+   competing run — reintroducing the duplicate-execution hazard the fence
+   exists to prevent.
+3. **`records_emitted` is never revised.** Records durably ingested before the
+   interruption stay committed. F7 makes this structural.
+
+The one real change: the raw `INSERT`s at `controller-boot.ts:526` and `:597`
+that bypass `emitSpineEvent` — and therefore had to hand-write their own
+`run_history` projection at `:657` and `:837` to avoid stranding rows at
+`running` — route through the owner module instead. The event and its
+projection already commit in one transaction; that stays. The bypass is the F8
+violation this design closes.
+
+The repair script remains a script. It is owner-operated, dry-run-first,
+`--limit`-bounded, and deliberately ignores the ownership filter — properties
+of an operational tool, not of a lifecycle transition. It should call the same
+predicate rather than reimplement it, which is the whole benefit.
+
+## (g) The D5 migration plan
+
+Writers cut over atomically per subsystem, old paths deleted in the same change,
+readers migrate after. Never let old and new writers coexist across a deploy
+boundary — every "parallel systems" period in this repo produced a masking pair.
+
+| Tranche | Writers cut over | Deleted in the same change |
+|---|---|---|
+| M1 | Schema + owner module (no callers yet) | nothing — additive only |
+| M2 | Terminal writes: `runtime/index.ts` ×6, `controller.ts` ×2, `terminal-run-commit-store.ts`, `local-device-terminal-collection.ts` | the direct `emitSpineEvent` terminal calls at those sites |
+| M3 | Admission + finalize: `activeRuns`, `settledRunIds`, `runWatchdogSettlements` | `settledRunIds`; hand-rolled CAS at `controller.ts:3249` |
+| M4 | Boot adjudication (T10/T11) | raw `INSERT`s at `controller-boot.ts:526`, `:597` |
+| M5 | Fence unification | `run_generation` column + `runGenerations` map |
+| M6 | Readers: the four terminal-set declarations collapse to one | `TERMINAL_RUN_EVENT_TYPES`, `SPINE_TERMINAL_EVENT_TYPES_SQL` |
+
+M6 is where the `run.abandoned` omission defect is repaired — as a consequence
+of single declaration, not as a separate fix.
+
+### The `drainActiveRuns` collision — verdict: **the brief's premise no longer holds**
+
+The brief asks me to confirm the Sidekiq *quiet* vs *drain* split and say which
+references migrate. Measured on this branch, `39d19704a`:
+
+- **139 total references** — the brief's number reproduces exactly.
+- **3** are in `openspec/changes/adjudicate-interrupted-runs-by-owner-epoch/**`
+  (prose in the landed sibling change).
+- **127** are in `reference-implementation/test/**`, of which **116** are call
+  expressions — overwhelmingly `await controller.drainActiveRuns(1000)` as
+  test teardown.
+- **9** are in source: `runtime/controller.ts` ×7 (one definition at `:4144`,
+  one interface member at `:786`, one export at `:4394`, four comments) and
+  `server/index.ts` ×2 — **both of which are comments, not call sites**.
+
+**There is no shutdown call site left to delete. It is already gone**, removed
+by the landed sibling change. `server/index.ts:8570` now reads "The shutdown
+path deliberately does NOT drain," and `:9686-9689` records that
+"`drainActiveRuns` itself stays on the controller: it means 'await in-flight
+runs' … Sidekiq draws the same line between *quiet* and *drain*."
+
+So: **the split is correct and is already implemented.** My verdict confirms the
+brief's reading of the semantics and corrects its state — this is not open work.
+The residual figures also differ slightly from the sibling change's prose, which
+says "137 references … 136 remain." Today's count is 139 including its own 3
+lines of prose, i.e. 136 outside that change plus 3 inside it. The numbers are
+consistent; the sibling was counting before it wrote about itself.
+
+Which references migrate under this design: **none of the 116 test calls.**
+`drainActiveRuns` means "await in-flight run promises" — a runtime affordance
+over `activeRunPromises` (JS promises, ruled "keep, out of scope" above), not a
+run-state mutation. It never transitions a run. It stays exactly where it is
+and keeps its name.
+
+## Risks / Trade-offs
+
+- [Design authored against a moving branch] -> A concurrent agent owns the
+  scheduler-conformance helper and the store drivers. The single-writer
+  inventory is a point-in-time read of `39d19704a` and must be re-verified
+  before M2 begins. Named as a residual risk, not mitigated here.
+- [`pending` is a new state with no existing projection] -> It is the only
+  addition, and it exists so admission has something to CAS against. If M1
+  measurement shows admission can safely CAS `∅ → running` directly, `pending`
+  should be dropped rather than kept for symmetry — a state that no transition
+  needs is a second truth in waiting.
+- [Absorbing `controller_active_runs` touches browser-surface leases] ->
+  `reconcileBrowserSurfaceLeasesAfterBoot` reads that table to decide which
+  leases are still held. Absorption must preserve that read or re-home it in
+  the same tranche; it is explicitly not a deletion.
+- [Deleting `needsHumanAttention` changes automation behavior] -> It is
+  in-memory and already lost on every restart, so its current behavior is
+  "suppress until restart." Moving it to a derived scheduler policy input makes
+  it durable, which is a *behavior change* and must be measured on the canary
+  rather than assumed neutral. This is the one item in the audit that is not
+  behavior-preserving on its face.
+- [CAS refusals become invisible] -> A transition that returns 0 rows is a
+  normal outcome, which means a bug that refuses *every* transition looks like
+  a quiet system. The canary metrics in `tasks.md` §6 therefore count
+  successful transitions, not just absence of anomalies.

+## Why
+
+Run state has no owner. It is spread across an append-only spine, a durable
+`run_history` projection, a durable `controller_active_runs` flight table, and
+at least five in-process maps in `runtime/controller.ts` — with no single
+component that decides which transitions are legal.
+
+The consequence is measured, not theorized. Terminal events are emitted from at
+least five modules: `runtime/index.ts` (lines 4071, 5117, 5172, 5367, 5414,
+5563), `runtime/controller.ts` (3707, 4083), `server/stores/terminal-run-commit-store.ts:117`,
+`operations/local-device-terminal-collection.ts:211`, and — bypassing
+`emitSpineEvent` entirely with raw `INSERT`s — `lib/controller-boot.ts`. Each
+site re-derives for itself what a legal terminal write is.
+
+Two facts found while writing this proposal show the cost directly:
+
+1. **The terminal set disagrees with itself.** `check-run-terminal.sql:15` and
+   `get-run-terminal-event.sql:13` list five terminal events including
+   `run.abandoned`. `connector-summary-read-model.ts:1253`
+   (`TERMINAL_RUN_EVENT_TYPES`) and `db.ts:5437`
+   (`SPINE_TERMINAL_EVENT_TYPES_SQL`) list four and omit `run.abandoned` — and
+   `db.ts`'s own comment says the two are "kept in exact sync." They are in
+   sync with each other and out of sync with the spine. An abandoned run is
+   therefore invisible to the connector-summary fold and to the
+   `connector_instance_id` backfill that fold depends on. The change that made
+   `abandoned` a first-class terminal state could not update these because
+   nothing declares the set once.
+
+2. **The epoch cannot fence a durable write.** `run.started` stamps
+   `boot_epoch`, `controller_id`, and `seq` into the spine event's `data_json`
+   (`runtime/index.ts:2745-2749`), but `run_history` has no epoch column on
+   either backend (`db.ts:1358`, `postgres-storage.ts:2169`). Every durable
+   run-state UPDATE is fenced on `AND status = 'running'` alone
+   (`run-history-writer.ts:355`, `:406`; `controller-boot.ts:670`). That fence
+   stops a double-terminal write but cannot stop a *stale epoch's* write: a
+   predecessor container that comes back from a pause still sees `running` and
+   still wins. Fencing exists in-process instead, as a hand-rolled
+   compare-and-swap on a JavaScript map (`controller.ts:3249`) plus a
+   `run_generation` counter (`controller.ts:1046`) — correct, and invisible to
+   the database that actually arbitrates.
+
+The historical incidents are all one shape. The GroupMe 503 was two components
+mutating run state through the same per-instance mutex, fixed by a guard in the
+scheduler (`scheduler.ts:636`) that mirrors "the guard `executeRun` already
+applies one step later" — the same rule stated twice because no component owns
+it. The collector-runner drain race was two clock reads with opposite boundary
+semantics. The YNAB wedge was an `activeRuns` entry that outlived its run and
+409-ed the instance until restart.
+
+This change writes down the machine: a closed state set, a transition table
+whose forbidden entries name the incident each one prevents, and a
+compare-and-swap predicate fenced by the owner epoch that already ships
+durably in `controller_identity` (`lib/controller-boot.ts:96-151`).
+
+## What Changes
+
+This change is **design and tests-first only**. It authors the contract and
+failing property-test skeletons; it writes no implementation. That is
+deliberate — the implementation is single-threaded and starts from a settled
+design.
+
+- Define the **closed run state set** and require it be declared exactly once,
+  so a terminal-set divergence like `TERMINAL_RUN_EVENT_TYPES` becomes a
+  compile-time impossibility rather than a comment asking two constants to
+  agree.
+- Rule on every side-state that lives beside run state today: `activeRuns`,
+  `controller_active_runs`, `run_generation`, `settledRunIds`,
+  `needsHumanAttention`, the scheduler's `cooling_off` and
+  `scheduler_dispatch_wedged` markers — each **absorbed**, **derived**, or
+  **deleted**, with the verdict recorded in `design.md`.
+- Define the **legal transition table**: each transition's precondition and its
+  single writer. Define the forbidden transitions, each annotated with the
+  historical incident it prevents.
+- Require every durable transition to be a **compare-and-swap fenced by owner
+  epoch** — `WHERE state = <expected> AND owner_epoch = <mine>` — and specify
+  the predicate for SQLite and PostgreSQL together, since this repo runs both
+  and a Postgres-only design has already shipped silent divergence here once.
+- Add an `owner_epoch` column to `run_history` on both backends, NULL-tolerant,
+  so the fence has a column to read. It does not exist today.
+- State the **D4 split**: the planner reads the machine and emits intents; only
+  the executor transitions. Scheduling *policy* stays out of the machine —
+  "runnable" is not "chosen to run next."
+- Formalize **successor adjudication** as a legal transition executed at boot,
+  replacing the sibling-script framing, with observable behavior unchanged.
+- Author **property-test skeletons**, one per historical incident cluster, each
+  failing or `.todo` and marked as a skeleton. A skeleton that passes without
+  implementation is the hollow-test defect this program exists to kill.
+
+## Capabilities
+
+### New Capabilities
+
+None.
+
+### Modified Capabilities
+
+- `reference-implementation-architecture`: Define the closed run state set and
+  its single declaration, the legal-transition table and its single-writer
+  rule, the epoch-fenced compare-and-swap requirement and its dual-backend
+  predicate, the planner/executor split, and successor adjudication as a
+  lifecycle transition.
+
+## Impact
+
+- Design-only in this change. No runtime file is modified.
+- New failing property-test skeletons under `reference-implementation/test/`,
+  named `run-lifecycle-*.property.test.ts`, excluded from the green gate until
+  the implementation change lands.
+- The implementation this design governs will touch
+  `reference-implementation/runtime/controller.ts`,
+  `runtime/index.ts`, `runtime/scheduler.ts`,
+  `server/stores/run-history-writer.ts`, `lib/controller-boot.ts`,
+  `server/db.ts`, and `server/postgres-storage.ts`.
+- Additive `run_history.owner_epoch` on SQLite and PostgreSQL, NULL-tolerant,
+  so existing databases migrate without a backfill.
+
+## Non-Goals
+
+- **Any implementation.** No writer is cut over here, no state is renamed in
+  code, no migration runs.
+- **Scheduling policy.** Fairness, throttling, backoff curves, and dispatch
+  ordering stay where they are. The machine answers whether a transition is
+  legal, never which connector should run next.
+- **Coverage-ledger and health work.** Steps 2 and 3 of this program depend on
+  this machine and are sequenced after it (D17).
+- **Auto-resume or auto-retry of interrupted runs.** Unchanged from the landed
+  owner-epoch change: adjudication is silent and the normal schedule picks the
+  work up.
+- **Committing staged cursors under interruption.** Still gated on the
+  bounded-`DETAIL_COVERAGE` evidence that production does not yet emit.
+
+## Residual risks
+
+- The transition table is authored against the code as read on
+  `fix/sweep-fairness-and-transformer-bounds` at `39d19704a`. A concurrent
+  agent owns the scheduler-conformance helper and the store drivers; if those
+  land new run-state writers, the single-writer inventory needs a re-read
+  before implementation begins.
+- One historical cluster — the maintenance-sweep shared-deadline starvation
+  family — is **not** expressible as an illegal run transition. It is a
+  fairness defect in a different subsystem, recorded in `design.md` as a
+  finding rather than forced into the table.

+## ADDED Requirements
+
+### Requirement: Run lifecycle SHALL be a closed state set declared exactly once
+
+The reference implementation SHALL define the run lifecycle as a closed set of
+states: `pending`, `running`, `awaiting_interaction`, `cancel_requested`,
+`succeeded`, `failed`, `surface_failed`, `cancelled`, and `abandoned`. The last
+five are terminal.
+
+The state set and its terminal subset SHALL be declared in exactly one place,
+and every consumer — projection, fold, query, backfill, and health read — SHALL
+derive from that declaration. No component SHALL restate the terminal set as
+its own literal collection.
+
+A run state SHALL NOT be represented by a boolean or marker stored beside the
+state. Any condition that describes where a run is in its lifecycle SHALL be a
+state in this set or SHALL be derived from one.
+
+A dispatch outcome that never started a run SHALL NOT be a run state. The
+scheduler MAY record such an attempt for cadence purposes, but the lifecycle
+SHALL NOT read it as the outcome of a run.
+
+#### Scenario: The terminal set has one declaration
+
+- **WHEN** any component tests whether a run event is terminal
+- **THEN** it SHALL consult the single declared terminal set
+- **AND** adding a terminal state SHALL require exactly one edit
+
+#### Scenario: An abandoned run is visible to every terminal reader
+
+- **WHEN** a run reaches `abandoned`
+- **THEN** every consumer of the terminal set SHALL observe that run as terminal
+- **AND** no consumer SHALL classify it as non-terminal because its own copy of
+  the terminal set omits `abandoned`
+
+#### Scenario: Both backends agree on the terminal set
+
+- **WHEN** the same run is read through the SQLite path and the PostgreSQL path
+- **THEN** both SHALL report the same terminal classification
+
+### Requirement: Every run-state transition SHALL be an epoch-fenced compare-and-swap
+
+Every durable run-state transition SHALL be expressed as a single conditional
+statement predicated on both the expected current state and the acting owner
+epoch. A transition SHALL NOT read the current state and then write it in a
+separate statement.
+
+A transition whose predicate matches no row SHALL be treated as refused. A
+refusal SHALL be an ordinary outcome: it SHALL NOT be retried by re-reading and
+re-writing, SHALL NOT raise owner attention, and SHALL NOT be recorded as a
+failure of the run.
+
+A run SHALL carry the identity of the owner epoch entitled to transition it,
+recorded durably in the same write that admits the run. A process whose epoch
+is not the run's owner epoch SHALL fail to transition that run **at the
+database**, not by an in-process check.
+
+The predicate SHALL be expressed so that it is identical in effect on SQLite
+and PostgreSQL. A null owner epoch SHALL be treated as unclaimed. The null arm
+SHALL be spelled out explicitly and SHALL NOT be written in a form that reduces
+to excluding null rows on either backend.
+
+Run identity for fencing purposes SHALL be the pair of run identifier and
+connector instance identifier, because a run identifier alone is not unique
+across connections.
+
+#### Scenario: A stale epoch's write is refused by the database
+
+- **WHEN** a process whose owner epoch is not the run's owner epoch attempts any
+  transition on that run
+- **THEN** the statement SHALL match no row
+- **AND** the run's state SHALL be unchanged
+
+#### Scenario: A transition from an unexpected state is refused
+
+- **WHEN** a transition expects a run to be in one state and the run is in
+  another
+- **THEN** the statement SHALL match no row
+- **AND** the caller SHALL treat the refusal as an ordinary outcome
+
+#### Scenario: A legacy run with no recorded owner epoch is claimable
+
+- **WHEN** a transition targets a run whose owner epoch is null
+- **THEN** the transition SHALL be permitted
+- **AND** the predicate SHALL NOT spare that run on either backend
+
+#### Scenario: Two connections sharing a run identifier are fenced apart
+
+- **WHEN** two runs on different connector instances share a run identifier
+- **THEN** a transition on one SHALL NOT match the other
+
+### Requirement: Exactly one component SHALL write run state
+
+All run-state transitions SHALL pass through a single owner module. No other
+component SHALL emit a run lifecycle event, update the durable run projection,
+or mutate an in-process structure that other components read as run state.
+
+A shared helper that many components import SHALL NOT satisfy this requirement.
+The requirement is one code path that owns the mutations, not one function that
+many code paths call.
+
+A component that writes run state SHALL NOT also decide which work runs next.
+
+#### Scenario: A second writer cannot terminalize a run
+
+- **WHEN** a component other than the owner module attempts to record a run's
+  terminal state
+- **THEN** the attempt SHALL be rejected
+- **AND** the run's terminal state SHALL remain whatever the owner module wrote
+
+#### Scenario: A terminal run cannot be revised
+
+- **WHEN** any component attempts a transition on a run already in a terminal
+  state
+- **THEN** the transition SHALL be refused
+- **AND** the run's recorded record count SHALL NOT be revised
+
+### Requirement: The planner SHALL read run state and SHALL NOT write it
+
+The component that decides which connector to run SHALL read the run lifecycle
+and emit intents. It SHALL NOT transition run state.
+
+A planner read SHALL NOT produce a durable side effect. An eligibility probe
+that reconciles, repairs, or otherwise writes on the read path SHALL count as
+writing run state, regardless of the name of the function that performs it.
+
+The lifecycle SHALL NOT encode scheduling policy. Backoff curves, cooldown
+windows, fairness rotation, admission budgets, and automation suppression SHALL
+remain the planner's. The lifecycle SHALL answer only whether a transition is
+legal.
+
+A run being eligible for a transition SHALL NOT mean the run has been chosen to
+execute.
+
+#### Scenario: The planner's eligibility probe writes nothing
+
+- **WHEN** the planner evaluates whether a connector instance is due
+- **THEN** that evaluation SHALL perform no durable write
+- **AND** it SHALL NOT acquire a write lock on the connector instance
+
+#### Scenario: Scheduling policy stays out of the lifecycle
+
+- **WHEN** a backoff, cooldown, or fairness rule changes
+- **THEN** the run lifecycle's states and transitions SHALL be unchanged
+
+### Requirement: Illegal transitions SHALL be refused rather than reconciled later
+
+The reference implementation SHALL define which transitions are legal, and
+SHALL refuse every transition outside that definition at the point of the
+write.
+
+The following SHALL be illegal: a transition attempted by any component other
+than the transition's declared writer; a transition whose actor epoch is not
+the run's owner epoch; a second terminal transition on a terminal run; any
+transition out of a terminal state; and the recording of an interrupted run as
+an observed failure.
+
+A run SHALL NOT be able to remain non-terminal indefinitely with no live owner
+epoch. A terminal state SHALL always be reachable for such a run, so that a run
+whose owner has died cannot permanently block its connector instance.
+
+#### Scenario: An interrupted run is not recorded as a failure
+
+- **WHEN** a run's owner process died without reporting an outcome
+- **THEN** the run SHALL transition to `abandoned`
+- **AND** no transition to `failed` SHALL be permitted for that reason
+
+#### Scenario: An ownerless run cannot block its connection forever
+
+- **WHEN** a run is non-terminal and no live epoch owns it
+- **THEN** a terminal transition SHALL be reachable for that run
+- **AND** its connector instance SHALL become able to admit a new run
+
+### Requirement: Successor adjudication SHALL be a lifecycle transition
+
+Marking a predecessor epoch's non-terminal runs as abandoned SHALL be a legal
+transition of the run lifecycle, executed by the owner module at boot. It SHALL
+NOT be a separate reconciliation path with its own copy of the state
+vocabulary.
+
+The transition SHALL preserve the adjudication behavior already established:
+it SHALL be idempotent per originating run-start event so repeated passes
+produce exactly one terminal event; it SHALL NOT adjudicate any run belonging
+to the newest boot epoch; it SHALL decide eligibility by epoch comparison
+rather than by an age threshold; and it SHALL NOT revise the record count of a
+run that ingested records before being interrupted.
+
+The terminal event and its durable projection SHALL be written in one
+transaction, so a run cannot be terminal in the event log while its projection
+still claims to be running.
+
+An owner-operated repair tool MAY apply this transition over a historical
+backlog with different scoping, but SHALL use the same transition rather than
+reimplementing it, and SHALL remain distinguishable in the recorded provenance
+of the events it writes.
+
+#### Scenario: Adjudication at boot is the same transition as everywhere else
+
+- **WHEN** the owner module adjudicates a predecessor epoch's non-terminal run
+- **THEN** it SHALL apply the same epoch-fenced transition used for every other
+  run-state change
+
+#### Scenario: The event and its projection commit together
+
+- **WHEN** adjudication terminalizes a run
+- **THEN** the terminal event and the durable projection SHALL commit in one
+  transaction
+- **AND** no run SHALL be observable as terminal in one and running in the other
+
+#### Scenario: Repeated adjudication is idempotent
+
+- **WHEN** adjudication runs twice over the same interrupted run
+- **THEN** exactly one terminal event SHALL exist for that run

+## 1. Design (this change)
+
+- [x] 1.1 Enumerate the closed state set, including `abandoned`, and rule
+      `skipped` out as a dispatch outcome rather than a run state.
+- [x] 1.2 Audit every boolean and side-state living beside run state and record
+      an absorb / derive / delete verdict for each in `design.md`.
+- [x] 1.3 Express every F1 incident cluster as a forbidden transition, and
+      report the one cluster that cannot be expressed as a finding.
+- [x] 1.4 Write the legal-transition table with each transition's precondition
+      and single writer, and the forbidden table annotated with the incident
+      each entry prevents.
+- [x] 1.5 Specify the compare-and-swap predicate for SQLite and PostgreSQL
+      together, including the explicit null arm.
+- [x] 1.6 State the planner/executor split and its policy guard.
+- [x] 1.7 Specify successor adjudication as a legal transition preserving
+      observable behavior.
+- [x] 1.8 Write the writers-first migration plan and the `drainActiveRuns`
+      verdict.
+
+## 2. Findings raised by this design (not fixed here)
+
+- [ ] 2.1 Six terminal-set declarations disagree with `lib/spine.ts:1066`. Four
+      omit `run.abandoned` (`connector-summary-read-model.ts:1253`,
+      `db.ts:5437`, `postgres-storage.ts:2692`, `connector-summary-evidence-engine.ts:1599`);
+      two omit `run.browser_surface_failed` (`lib/postgres-spine.ts:570`,
+      `postgres-storage.ts:2336`). Closed by M6, not before.
+- [ ] 2.2 `insert-run-history.sql:40` and `scheduler-store.ts:1018` upsert
+      `status = excluded.status` with no `status = 'running'` fence, so a
+      scheduler retry can overwrite a terminal status.
+- [ ] 2.3 `controller-boot.ts:829` (PostgreSQL drift repair) matches on
+      `run_id` alone while its SQLite twin at `:788` fences on
+      `connector_instance_id`.
+- [ ] 2.4 `run_generation` is written from a monotonic counter
+      (`controller.ts:3187`) and from a retry `attempt`
+      (`scheduler/run-executor.ts:819`) — one column, two meanings.
+- [ ] 2.5 Two `createReferenceSchedulerManager` definitions exist
+      (`server/index.ts:8828` live, `scheduler-manager-factory.ts:374`
+      test-only). Resolve before M2.
+
+## 3. Schema (implementation, not this change)
+
+- [ ] 3.1 Add NULL-tolerant `run_history.owner_epoch TEXT` on SQLite via
+      `addColumnIfMissing`, mirroring the `run_generation` migration.
+- [ ] 3.2 Add `run_history.owner_epoch TEXT` on PostgreSQL via
+      `ALTER TABLE ... ADD COLUMN IF NOT EXISTS`, **in the same change** as 3.1.
+- [ ] 3.3 Stamp `owner_epoch` in the same write that admits a run.
+- [ ] 3.4 Add a dual-backend test proving the column exists and is written on
+      both, so a single-backend migration cannot ship.
+
+## 4. The owner module (implementation, not this change)
+
+- [ ] 4.1 Declare the state set and terminal subset once; every consumer derives.
+- [ ] 4.2 Implement the transition table T1-T11 as epoch-fenced compare-and-swap.
+- [ ] 4.3 Return refusal as an ordinary outcome; never retry blindly.
+- [ ] 4.4 Route boot adjudication (T10/T11) through the same predicate.
+- [ ] 4.5 Cut writers over per the M1-M6 tranches, deleting each old path in the
+      same change as its replacement.
+
+## 5. Property-test skeletons (this change — must fail or `.todo`)
+
+Each skeleton is authored `.todo` or asserting against the not-yet-existing
+owner module, and is marked in-file as a skeleton. **A skeleton that passes
+before implementation is the defect this program exists to kill.** Each names
+its property, generator, and invariant, and maps to a forbidden transition.
+
+- [x] 5.1 `run-lifecycle-transition-legality.property.test.ts` — **F7, F5.**
+      Generator: random sequences of transition attempts drawn from the full
+      state × transition cross-product. Invariant: the observed state after any
+      sequence is reachable from the initial state by legal transitions only,
+      and a terminal state is never left.
+- [x] 5.2 `run-lifecycle-epoch-fencing.property.test.ts` — **F2.** Generator:
+      interleavings of two actors with distinct epochs attempting transitions on
+      one run. Invariant: only the run's owner epoch ever changes state; the
+      stale actor's statement matches zero rows. Runs on both backends.
+- [x] 5.3 `run-lifecycle-single-terminal.property.test.ts` — **F5, F4.**
+      Generator: concurrent terminal attempts of differing kinds, including a
+      boot adjudicator racing an executor. Invariant: exactly one terminal state
+      results; an interrupted run terminalizes `abandoned`, never `failed`.
+- [x] 5.4 `run-lifecycle-planner-writes-nothing.property.test.ts` — **F1.**
+      Generator: planner eligibility evaluations against instances in every
+      state, including one with a run in flight. Invariant: zero durable writes
+      and zero connector-instance write-lock acquisitions occur during a planner
+      read. This is the GroupMe 503 as a property.
+- [x] 5.5 `run-lifecycle-no-permanent-wedge.property.test.ts` — **F6.**
+      Generator: runs abandoned mid-flight by an epoch that never returns.
+      Invariant: a terminal state is always reachable, and the connector
+      instance can admit a new run afterwards. This is the YNAB wedge.
+- [x] 5.6 `run-lifecycle-cas-no-stale-premise.property.test.ts` — **F3.**
+      Generator: transitions whose observed state is mutated by a competing
+      actor between the caller's read and its write. Invariant: no transition
+      commits on a premise that changed under it. This is the drain/clock race.
+- [x] 5.7 `run-lifecycle-terminal-set-agreement.property.test.ts` — **the
+      declaration requirement.** Generator: every terminal state, read through
+      every consumer of the terminal set. Invariant: all consumers agree, and
+      both backends agree. Fails today on the six divergent declarations.
+- [x] 5.8 `run-lifecycle-adjudication-idempotence.property.test.ts` — **T10/T11.**
+      Generator: repeated adjudication passes over overlapping orphan sets,
+      including a run in the newest boot epoch. Invariant: exactly one terminal
+      event per orphan; newest-epoch runs are never adjudicated; record counts
+      are never revised.
+
+- [ ] 5.9 Register 5.1-5.8 in the suite as expected-failing until the owner
+      module lands, so their red state is deliberate and visible rather than
+      an unexplained broken build.
+
+## 6. Pre-registered canary metrics (D15)
+
+Registered **before** any Step 1 deploy. Post-hoc criteria are how "green"
+claims died in this program.
+
+- [ ] 6.1 **Restarts.** 20 consecutive controller restarts in a replaced
+      container with zero adjudication anomalies: every `run.started` without a
+      terminal event belongs to the newest boot epoch, and no run holds two
+      terminal events. Measured by query, not by log reading.
+- [ ] 6.2 **Race-class property tests green.** All of 5.1-5.8 pass on both
+      SQLite and PostgreSQL. Any skipped test counts as a failure.
+- [ ] 6.3 **Transition throughput is non-zero.** Count of successful transitions
+      per state pair over the canary window is greater than zero for T1, T2, and
+      at least one terminal transition. A machine that refuses everything would
+      otherwise satisfy every "zero anomalies" metric.
+- [ ] 6.4 **Refusal rate is bounded.** Refused transitions stay under 1% of
+      attempts outside adjudication. A rising refusal rate means the expected
+      state is being computed wrong somewhere.
+- [ ] 6.5 **Behavior preservation (D14).** Per-connector run outcomes over the
+      canary window match the pre-change baseline in kind and count. Terminal
+      state distribution shifts only by the `failed` → `abandoned`
+      reclassification the design intends.
+- [ ] 6.6 **No permanent wedge.** Zero connector instances refusing a new run
+      with `active_run_exists` for longer than one scheduling interval.
+      Baseline: the UAT instance previously held 7 of 8 `running` rows as
+      zombies up to two days old.
+- [ ] 6.7 **Dual-backend parity.** 6.1-6.6 measured on both backends. A
+      PostgreSQL-only or SQLite-only pass is a failure, not a partial success.
+
+## 7. Validation
+
+- [ ] 7.1 `openspec validate own-run-lifecycle-state-machine --strict`.
+- [ ] 7.2 `openspec validate --all --strict` against the recorded baseline of 11
+      pre-existing failures, so this change's contribution is distinguishable.
+- [ ] 7.3 Re-verify the single-writer inventory against the branch head before
+      M2 begins; it is a point-in-time read and concurrent agents own adjacent
+      files.

+## Context
+
+The sibling change `adjudicate-interrupted-runs-by-owner-epoch` settled who
+writes an interrupted run's terminal state: the successor, by owner epoch, with
+no drain. It deliberately left one question open — whether a staged cursor may
+be committed when a run does not reach `succeeded`.
+
+That question cannot be answered by policy, because the runtime has no
+information to reason with. `commitState(stream, cursor)` is already a
+per-stream idempotent `PUT`, and the plumbing is exercised on every successful
+run. Only the *decision* is deferred to DONE, at a single gate:
+
+```
+if (persistState && (terminalStatus === "succeeded" || isCertifiedStreamCollectionFailure))
+```
+
+`reference-implementation/runtime/index.ts` — located by content, not by line
+number, since the research entry's line numbers have since drifted.
+
+So the missing thing is not a policy. It is a vocabulary.
+
+## Goals / Non-Goals
+
+**Goals:**
+
+- A connector can state a checkpoint claim the runtime can check without
+  knowing anything about the connector.
+- A connector that cannot state a truthful claim is *rejected*, and that
+  rejection is the standard working, not a failure of the standard.
+- The representation admits coarse-granularity truth, so a connector with a
+  coarse cursor is judged on whether it can prove a coarse unit closed, not
+  punished for lacking a finer one.
+- The representation is storage-free, so the terminal form is additive.
+
+**Non-Goals:**
+
+- Fleet-wide adoption. See the proposal; this is the point, not a concession.
+- A storage, compaction, or interval-merge layer.
+- Rescuing a connector whose scan is unordered.
+
+## Decisions
+
+### Qualification is the product, not a side effect
+
+A prototype tested a four-field claim contract against `gmail`, `slack`, and
+`heb`. Two of the three could not state a truthful claim, and that was first
+recorded as the design failing.
+
+That framing is wrong and is corrected here. **A contract that admits every
+connector would be worthless.** Its entire job is to separate cursors that can
+express a truthful boundary from cursors that cannot. `slack` and `heb` failing
+at fine granularity is the qualifier discriminating correctly — it is the
+evidence that the standard has teeth, not evidence against it.
+
+The correct reading of the prototype:
+
+| Connector | Fine granularity | Day granularity | Why |
+| --- | --- | --- | --- |
+| `gmail` | Qualifies | n/a | IMAP UID order, and it already carries `uidvalidity` as an identifier-space epoch |
+| `heb` | Fails | **Qualifies, under the closed-day rule** | Cursor is `YYYY-MM-DD`; orders sort by full timestamp, so within-day position is inexpressible |
+| `slack` | Fails | Fails | No ordered scan at all; no granularity rescues it |
+
+### The representation is covered intervals; debt is derived
+
+The prototype's contract declared a `complete_through` boundary *and* a
+separate `debt` list. Two fields describing one fact can disagree, and nothing
+in the protocol would catch it.
+
+This change adopts **covered intervals** instead: the claim carries a set of
+intervals over a declared space, and outstanding debt is whatever is *not*
+covered. Debt is derived, so the two cannot contradict each other. A
+newest-first walk states its truth directly — after page 1 `heb` covers
+`[newest_day, newest_day]` and owes everything below, and that is a correct
+claim at every instant rather than a promise about the future.
+
+This also subsumes the two-pointer shape without special-casing it. `gmail`'s
+`forward_uidnext` plus `backfilled_through_uid`/`target_uid` is exactly two
+covered intervals with a gap between them.
+
+No storage layer is specified. An implementation may keep one interval or a
+thousand; the representation does not care, which is what makes a later
+compaction layer additive.
+
+### A claim carries a granularity, and a coarse claim is still true
+
+The prototype tested claims at the granularity of the provider's sort key. That
+is the wrong test for a connector whose cursor is coarser than its sort key,
+which is precisely `heb`'s situation.
+
+A day-boundary claim — "every order dated D or later is accounted for" — is
+truthful even when within-day ordering is inexpressible, **provided the
+connector can prove the day is closed**. Coarsening the granularity does not
+weaken the claim's meaning; it widens the unit over which completeness must be
+proven, which makes the claim *harder* to earn, not easier.
+
+The claim's granularity is declared, and every interval endpoint is a position
+at that granularity. A day-granularity claim covering `[D, D]` asserts that
+every item in the whole of day `D` is accounted for. It does not assert
+anything about ordering inside `D`, and it does not need to.
+
+### The `heb` day-granularity verdict: qualifies, under a closed-day rule
+
+**Verdict: `heb` `orders` qualifies at day granularity, and only for days
+proven closed. The naive day claim is unsafe and is rejected.**
+
+Two independent hazards put holes *inside* a day, and each is answered:
+
+**Hazard 1 — the newest day is open.** `runForwardScan`
+(`packages/polyfill-connectors/connectors/heb/index.ts:868-925`) walks list
+pages newest-first and tracks `newestOrderDate` as a running max
+(`:901-903`). At any instant mid-walk, the newest day seen may be only
+partially enumerated: orders from the same day sort by full timestamp and can
+straddle a page boundary, so page 1 may hold three of that day's five orders.
+Claiming `[newestOrderDate, ...]` from page 1 would claim a day whose remaining
+orders have not been seen.
+
+The rule that answers it: **a day may be claimed only once a strictly older day
+has been observed.** Seeing an order dated `D-1` proves the newest-first walk
+has passed every order dated `D`. This is a property of the walk order, which
+`heb` genuinely has (globally reverse-chronological, per `resumeBoundary`'s
+own doc comment: "H-E-B's order list is globally reverse-chronological (not
+year-partitioned like Amazon)"). The newest day observed is therefore always
+excluded from the claim — it is exactly the open unit.
+
+**Hazard 2 — `dateDropped` puts a hole in a day that cannot be located.** This
+is the sharper one, and it is why the rule must be a *closed*-day rule rather
+than just an *older-day-seen* rule.
+
+`processListOrder` (`:829-854`) parses each order's date. When
+`parseOrderDate` returns null — it is a `new Date(raw)` parse of DOM free text
+(`connectors/heb/parsers.ts:341-350`) — the order is pushed to
+`ordersCoverage.dateDropped` (`:851`) and the function `return`s before
+`emitOrderAndItems`. The order is *considered but not covered*, exactly as the
+`OrdersCoverage` doc comment states.
+
+The hazard is that **a date-dropped order has no date**. It cannot be
+attributed to any day, so it cannot be excluded from a specific day's interval.
+It is a hole of unknown position, and any interval claimed on a run that
+dropped a date might be the interval containing it.
+
+The rule that answers it: **a claim is emitted only when `dateDropped` is empty
+for the run.** A single unparseable date withholds the entire claim for that
+run. This is coarse and deliberately so — it fails closed, it needs no
+attribution machinery, and the fallback is today's behavior. `heb` runs are
+small, so withholding a whole run's claim is cheap.
+
+A third, lesser hazard is worth naming because it bounds the claim rather than
+blocking it: `MAX_LIST_PAGES = 50` (`:64`) and the `maxPage` exhaustion at
+`:919-921` can end a walk early. This does not threaten the claim, because a
+truncated walk simply covers fewer days — the *upper* part of the space is
+still proven, and the untraversed remainder is uncovered by construction. This
+is the covered-intervals representation earning its place: truncation is
+expressible as a smaller covered set, whereas under a single `complete_through`
+watermark it would be indistinguishable from completion.
+
+Note that `CHECKPOINT_OVERLAP_DAYS = 60` (`:70`) is **not** part of the safety
+argument. It re-scans a 60-day window to catch status transitions on
+already-seen orders (`resumeBoundary`, `:1064-1073`). It is a freshness device,
+not a completeness device, and treating it as a safety margin would be exactly
+the kind of accidental-timing invariant this contract exists to replace.
+
+**Confidence.** High on the source reading: the scan order, the `dateDropped`
+path, and the single post-scan `STATE` emission (`:1183-1186`) were each read
+directly. Not verified live — `heb` sign-in costs the owner a real OTP, so no
+run was triggered. Both rules fail closed, so a misreading withholds a commit
+rather than losing data.
+
+### `slack` remains disqualified, and the emitted-watermark fix does not change it
+
+**Verdict: disqualified at every granularity.**
+
+`grep -c "ORDER BY" packages/polyfill-connectors/connectors/slack/index.ts`
+returns **0**, reproduced on this branch. Slack's messages pass is one flat
+interleaved query over the archive with no ordering, so any mid-run watermark
+is a maximum over an arbitrary subset of rows, not the top of a contiguous
+prefix. An interval claimed over that input asserts coverage of everything
+below the maximum, while rows below it may not have been visited at all. That
+is not a weaker claim than `heb`'s — it is a false one, and coarsening the
+granularity makes it a more confident falsehood rather than a safer claim. A
+day-granularity claim over an unordered scan asserts *more*.
+
+The sibling branch `fix/slack-emitted-watermark-0821` (head `9541a10db`) was
+checked rather than assumed. It is a real and valuable fix: it advances the
+durable watermarks only for rows actually emitted and accepted, removes the
+`COALESCE(t.last_ts, ?)` global-floor inheritance, and parenthesizes an
+operator-precedence bug in the same predicate. **It does not add an ordering.**
+`grep -c "ORDER BY"` on that branch's `connectors/slack/index.ts` also returns
+**0**. The fix makes the watermark honest about *which rows it counted*; it
+does not make the scan a prefix. Disqualification stands, and it stands for the
+same reason it did before.
+
+This is worth stating plainly because the two defects are easy to conflate: the
+emitted-vs-iterated defect was a bug *within* an unclaimable design, and fixing
+it does not make the design claimable.
+
+### Rejected representations
+
+- **`complete_through` plus a declared `debt` list.** Two fields for one fact,
+  free to disagree. Covered intervals derive debt instead.
+- **A `covered`/`considered` ratio.** Measures detail-hydration honesty, not
+  position. `github` `starred` reports itself `partial` yet still advances its
+  watermark past dropped entries; `jellyfin` `items` writes a cursor nothing
+  reads. A ratio both over- and under-approximates cursor safety.
+- **A `safe: true` boolean.** Unfalsifiable self-attestation.
+- **A connector version or capability flag.** An allowlist with extra steps.
+- **A global floor for unseen partitions.** Deliberately inexpressible. A
+  partition-scoped claim may move only its own partition, which makes Slack's
+  `COALESCE` shape unrepresentable rather than merely discouraged.
+
+## The ideal-compatibility rule
+
+Every later fix on this program obeys three constraints:
+
+1. **No new health logic reading evidence projections.** Health is derived from
+   the ledger, not from re-deriving state out of projections.
+2. **No new implicit run-state flags.** Run state is explicit and durable, not
+   inferred from the presence or absence of a side-channel.
+3. **No new cursor shapes violating the claim schema.** A new cursor either
+   states a checkpoint claim or stays silent; it does not invent a third
+   dialect.
+
+**Placement, and why.** The rule lives here in `design.md` as its normative
+home, and is restated as a requirement in this change's `polyfill-runtime`
+spec delta so it survives archival into `openspec/specs/`.
+
+It is deliberately **not** added to `openspec/README.md`. That file documents
+the OpenSpec process — artifact kinds, lifecycle, validation commands, the
+closeout checklist — and is scoped to how changes are written, not to what any
+particular change may contain. A program-specific engineering constraint placed
+there would be read by every contributor to every unrelated change, which is
+how process docs accrete rules nobody applies. There is also no
+CONTRIBUTING-adjacent surface in this repository that governs runtime
+architecture.
+
+The spec delta is the surface that actually binds. A design.md is advisory and
+is archived with its change; a requirement in `openspec/specs/polyfill-runtime/`
+is the repository's standing statement of how the runtime behaves, and is what a
+later contributor or agent validates against. Putting the rule anywhere that
+does not survive `openspec archive` would guarantee it is forgotten by the step
+that needs it most, which is Step 3 of this program.
+
+## Corrections to prior statements
+
+### The restart worst case is redo since the last COMMITTED cursor
+
+Earlier statements — including the research entry
+`ai/research/pdpp/the-checkpoint-protocol-must-carry-a-proven-boundary-and-an-identifier-space-epoch-...md`
+§5 — said the residue of an interruption is that "work done *since* the last
+checkpoint is redone."
+
+**That is wrong, and it understates the cost.** Staged cursors are discarded on
+interruption, so nothing a run staged mid-flight survives. The correct statement
+is that for a `commit_on_success` connector, an interruption redoes work since
+the last **committed** cursor — which is the cursor written by the last
+*successful* run, effectively the run start.
+
+Verified by content on this branch, since line numbers have drifted:
+
+- `newState` is a plain in-memory `Record<string, unknown>`
+  (`reference-implementation/runtime/index.ts:2762`), assigned on each `STATE`
+  message (`:4237`).
+- `commitState` has exactly two call sites (`:5278`, `:5322`), both inside the
+  DONE gate at `:5266`. There is no mid-run commit path.
+
+So a staged cursor has no durable effect until DONE, and an interrupted run
+leaves the committed cursor exactly where the previous successful run left it.
+
+This matters to the program's cost-benefit and is corrected because it is
+accurate, not because it is convenient: it makes the pain *larger* than
+previously stated, which strengthens the case for the ledger. The 465 runs that
+ingested 897,916 records and advanced no cursor are the direct measurement of
+this, and they are not "since the last checkpoint" losses — they are whole-run
+losses.
+
+## Risks / Trade-offs
+
+- [A connector states a claim it cannot honor] -> The runtime does not trust the
+  claim alone. It checks the claim against a fact it wrote itself: a claim that
+  advances a position with zero durably ingested records for that stream this
+  run is staged, not committed. Flink's rule applies — the durable ingest *is*
+  the pre-commit.
+- [The closed-day rule withholds too often on `heb`] -> It withholds a run's
+  claim whenever any date fails to parse. The fallback is today's behavior
+  (`commit_on_success`), so the failure mode is a redone run, never a lost
+  order. If withholding proves common in practice, the fix is to attribute
+  dropped orders to a day, not to weaken the rule.
+- [Covered intervals grow unbounded] -> Out of scope by construction. The
+  representation is storage-free precisely so a compaction layer can be added
+  additively once a real growth pattern is measured rather than guessed.
+- [Coarse granularity becomes an escape hatch] -> It is the opposite: a coarser
+  unit must be proven complete over a wider range, so it is harder to earn.
+  `slack` demonstrates the floor — coarsening does not rescue a scan that has no
+  order.
+- [The `heb` verdict is wrong because it was not run live] -> Both rules fail
+  closed. The cost of a misreading is a withheld commit.
+
+## Migration Plan
+
+Sequenced cheapest-value-first. This change lands only the standard; the
+numbered steps below are later tranches.
+
+1. Add the optional `checkpoint_claim` field to the protocol. Inert — no
+   connector emits it and no behavior changes.
+2. Implement the runtime decision procedure. Still inert for every connector
+   that stays silent.
+3. Claim it in `gmail` `messages` first: it already carries all the needed
+   structure including `uidvalidity`, and it is 203,417 of the lost records.
+4. `chatgpt` and `codex` next — together 657,477 records, the largest single
+   win in the fleet.
+5. `heb` under the closed-day rule, if and only if its interruption pain is
+   shown to be real. `heb` p50 run duration is 25.2s, so it may correctly never
+   qualify for the *investment* even though it qualifies for the *contract*.
+
+Rollback at any step is deletion of an optional field; a connector that stops
+claiming reverts to `commit_on_success` with no data migration.

+## Why
+
+The connector→runtime protocol types a checkpoint payload as `cursor: unknown`
+(`packages/polyfill-connectors/src/connector-runtime-protocol.ts`), and the
+runtime's complete validation of it is that it is a non-array object or null.
+The runtime therefore has zero information with which to tell a safe cursor
+from an unsafe one, and `commit_on_success` is what that absence of information
+forces — a no-information fallback, not a risk judgment.
+
+The cost is measured on the live spine: fleet-wide, 130,517 `run.state_staged`
+against 75,513 `run.state_advanced`, so 42% of staged checkpoint work is
+discarded. Restricting to terminal runs that staged at least one stream and
+reported `checkpoint_commit_status = not_committed`, 465 runs across 14
+connectors durably ingested 897,916 records and advanced no cursor.
+
+Today, cursor safety is not a property of the cursor. It is a property of when
+a connector happens to emit. `heb` `orders` sets `newestOrderDate` from page 1
+before the older pages are walked, and is safe only because its single
+`emit({ type: "STATE" ... })` sits after `runForwardScan` returns. Move that
+emit inside the loop and it becomes permanent data loss, with no runtime check
+firing and no test failing. That is an unowned invariant held in place by code
+review alone.
+
+This change writes down the contract that lets a connector *say* whether its
+checkpoint is safe, and lets the runtime check that claim against a fact the
+runtime itself wrote.
+
+## What Changes
+
+This change is a **qualification standard**, not a migration plan. It defines
+what a connector must be able to express to earn incremental commit, and
+accepts that most of the fleet will never express it.
+
+- Define an optional `checkpoint_claim` on the `STATE` message carrying a
+  declared identifier space with an epoch, a set of **covered intervals** over
+  that space, and an optional partition key. Outstanding debt is **derived from
+  the gaps** between covered intervals; it is never separately declared, so the
+  two cannot disagree.
+- Define the runtime's connector-agnostic decision procedure. Absent claim,
+  mismatched epoch, or a claim advancing with no durably ingested records this
+  run ⇒ stage only. A partition-scoped claim moving any other partition's
+  position ⇒ protocol violation.
+- Define **claim granularity**. A claim's interval endpoints are positions in a
+  declared space at a declared granularity. A coarse granularity (a day) is a
+  truthful claim when a finer one is not expressible, provided the connector
+  can prove every item in that coarse unit was accounted for.
+- Record the qualification results for the three prototyped connectors as
+  evidence that the qualifier discriminates: `gmail` qualifies, `slack` is
+  disqualified at every granularity, and `heb` qualifies **only** at day
+  granularity and **only** under a closed-day rule this change specifies.
+- Adopt an ideal-compatibility rule constraining every later fix on this
+  program: no new health logic reading evidence projections, no new implicit
+  run-state flags, no new cursor shapes violating the claim schema.
+
+Non-qualifying connectors keep `commit_on_success` unchanged and forever. That
+is a correct permanent answer, not a temporary one.
+
+## Capabilities
+
+### New Capabilities
+
+None.
+
+### Modified Capabilities
+
+- `polyfill-runtime`: Define the checkpoint claim's covered-intervals
+  representation, the identifier-space epoch, claim granularity and the
+  closed-unit rule, the runtime's commit decision procedure, the
+  disqualification criteria, and the ideal-compatibility rule.
+
+## Impact
+
+- No production code changes in this tranche. This change is the qualification
+  standard; implementation is sequenced behind it.
+- When implemented: `packages/polyfill-connectors/src/connector-runtime-protocol.ts`
+  gains an optional field, and `reference-implementation/runtime/index.ts`
+  gains the decision procedure at its `STATE` handler. Both are additive — a
+  connector that says nothing keeps today's behavior exactly.
+- The representation is deliberately storage-free, so a later compaction or
+  interval-store layer is an additive migration rather than a rewrite.
+
+## Non-Goals
+
+- **Fleet-wide adoption.** Explicitly not a goal. A connector whose runs take
+  40 seconds should redo its run; buying the contract there is cost with no
+  benefit. The contract is bought only where interruption pain is real, which
+  the live measurement localizes to a handful of connectors.
+- **A storage or compaction layer for intervals.** This change specifies the
+  representation only. How intervals are stored, merged, or bounded is left
+  open so the terminal form is an additive migration.
+- **Committing staged cursors under an `INTERRUPTED` terminal state.** That
+  remains gated on the sibling change
+  `adjudicate-interrupted-runs-by-owner-epoch`, whose measurement stands: zero
+  of 34,928 `run.detail_coverage_declared` events carry `boundary`,
+  `slice_start`, or `slice_end`.
+- **Rescuing `slack`.** No granularity coarsening makes an unordered scan
+  claimable. Slack needs an ordered scan first; that is separate work.
+- **Any per-connector allowlist.** If one becomes necessary, the contract has
+  failed — the claim is meant to travel with the data.
+
+## Residual risks
+
+- The `heb` day-granularity verdict is derived from source reading, not from a
+  live run. `heb` sign-in costs the owner a real OTP, so live confirmation is
+  deferred rather than performed. The closed-day rule is written to fail closed,
+  so a wrong reading withholds a commit rather than losing data.

+## ADDED Requirements
+
+### Requirement: A checkpoint claim SHALL be optional, and its absence SHALL mean commit_on_success
+
+A connector `STATE` message MAY carry a `checkpoint_claim`. A connector that
+emits no claim SHALL retain `commit_on_success` behavior unchanged: its staged
+cursor SHALL be committed only when the run reaches a terminal status that
+already permits commit.
+
+The runtime SHALL NOT require a claim from any connector, and SHALL NOT
+maintain a per-connector allowlist of connectors permitted to claim. Eligibility
+SHALL be carried by the claim itself, so a connector qualifies or fails to
+qualify by what it can express, not by enumeration.
+
+Fleet-wide adoption SHALL NOT be treated as a goal. A connector whose runs are
+short enough that redoing one is acceptable recovery MAY correctly never emit a
+claim.
+
+#### Scenario: A silent connector keeps today's behavior
+
+- **WHEN** a connector emits a `STATE` message with no `checkpoint_claim`
+- **THEN** the runtime SHALL stage the cursor
+- **AND** it SHALL NOT commit that cursor before the run reaches a terminal
+  status that already permits commit
+
+#### Scenario: Qualification is not an allowlist
+
+- **WHEN** the runtime evaluates whether a checkpoint may be committed
+  incrementally
+- **THEN** the decision SHALL depend only on the claim and on facts the runtime
+  itself recorded
+- **AND** it SHALL NOT depend on the connector's name or version
+
+### Requirement: A checkpoint claim SHALL declare an identifier space with an epoch
+
+A `checkpoint_claim` SHALL name the identifier space its positions belong to,
+and that name SHALL incorporate an epoch that changes whenever the provider
+re-seeds the space.
+
+The runtime SHALL compare a claim's space to the stored space by equality
+alone. When they differ, the runtime SHALL stage the cursor only, SHALL discard
+the prior position, and SHALL NOT interpret positions from one epoch as
+comparable to positions from another.
+
+The runtime SHALL NOT require any provider-specific knowledge to perform this
+comparison.
+
+#### Scenario: A re-seeded identifier space invalidates the prior position
+
+- **WHEN** a claim declares a space that differs from the stored space
+- **THEN** the runtime SHALL NOT commit the claimed position
+- **AND** the prior position SHALL be discarded rather than compared
+
+#### Scenario: A matching space permits comparison
+
+- **WHEN** a claim declares a space equal to the stored space
+- **THEN** the claim's positions SHALL be treated as comparable to the stored
+  position
+
+### Requirement: A checkpoint claim SHALL represent coverage as intervals, with debt derived from the gaps
+
+A `checkpoint_claim` SHALL express what it has accounted for as a set of
+covered intervals over its declared space. Outstanding debt SHALL be derived as
+the complement of the covered set within that space, and SHALL NOT be declared
+as a separate field.
+
+A claim SHALL NOT carry both a coverage assertion and an independently declared
+debt assertion, because two fields describing one fact can disagree and the
+runtime cannot adjudicate between them.
+
+An empty covered set SHALL be a valid claim asserting that nothing is yet
+accounted for. Omitting the covered set entirely SHALL be rejected as
+malformed; the two SHALL NOT be treated as equivalent.
+
+This requirement SHALL constrain the representation only. It SHALL NOT mandate
+any storage, compaction, or interval-merge strategy, so that such a layer may
+be added later without changing the claim's meaning.
+
+#### Scenario: A newest-first walk states a truthful partial claim
+
+- **WHEN** a connector walking newest-first has accounted for only the newest
+  part of its space
+- **THEN** it MAY claim exactly that part as covered
+- **AND** the remainder SHALL be treated as outstanding debt without being
+  separately declared
+
+#### Scenario: A two-pointer connector needs no special case
+
+- **WHEN** a connector maintains both a forward watermark and a backfill floor
+- **THEN** it SHALL express that state as two covered intervals separated by a
+  gap
+
+#### Scenario: An omitted covered set is malformed
+
+- **WHEN** a claim omits its covered set entirely
+- **THEN** the runtime SHALL reject the claim as malformed
+- **AND** it SHALL NOT treat the claim as asserting empty coverage
+
+### Requirement: A checkpoint claim SHALL declare its granularity, and a coarse claim SHALL cover whole units
+
+A `checkpoint_claim` SHALL declare the granularity at which its interval
+endpoints are positions. A claim MAY declare a granularity coarser than the
+provider's own sort order when a finer position is not expressible from the
+connector's cursor.
+
+A coarse-granularity interval SHALL assert that every item in every unit it
+covers has been accounted for. It SHALL NOT assert anything about ordering
+within a unit, and SHALL NOT be required to.
+
+A unit SHALL be claimed only when the connector can prove that unit closed. A
+unit that may still receive items the connector has not seen SHALL NOT be
+claimed, regardless of how many of its items have been accounted for.
+
+Coarsening granularity SHALL NOT weaken what a claim asserts. A coarser unit
+SHALL require completeness to be proven over a wider range, so it SHALL be
+harder to earn than a finer one, not easier.
+
+#### Scenario: A coarse claim is truthful when the unit is closed
+
+- **WHEN** a connector's cursor cannot express a position finer than a whole
+  unit
+- **AND** it can prove every item in that unit was accounted for
+- **THEN** it MAY claim that unit as covered at that granularity
+
+#### Scenario: The open unit at the frontier is not claimed
+
+- **WHEN** a connector walking in one direction has reached a unit but cannot
+  prove it has passed every item in that unit
+- **THEN** it SHALL NOT claim that unit
+- **AND** it MAY claim only units it has provably passed
+
+#### Scenario: An unattributable omission withholds the claim
+
+- **WHEN** a connector enumerated an item but could not determine which unit it
+  belongs to
+- **THEN** it SHALL NOT emit a claim covering any unit for that run
+- **AND** the run SHALL fall back to `commit_on_success` behavior
+
+#### Scenario: A truncated walk claims less rather than claiming falsely
+
+- **WHEN** a walk ends early because a pagination ceiling was reached
+- **THEN** the claim SHALL cover only the units actually traversed
+- **AND** the untraversed remainder SHALL remain outstanding debt
+
+### Requirement: The runtime SHALL check a claim against durable ingest before committing
+
+The runtime SHALL NOT commit a claimed position on the strength of the claim
+alone. A claim that advances a stream's position SHALL be committed only when
+the runtime itself recorded durable ingest for that stream during the run.
+
+A claim that advances a position with no durably ingested records for that
+stream in that run SHALL be staged only.
+
+The runtime's decision procedure SHALL be connector-agnostic and SHALL depend
+only on the claim's declared fields and on facts the runtime recorded.
+
+#### Scenario: A claim without corresponding durable ingest is not committed
+
+- **WHEN** a claim advances a stream's position
+- **AND** the runtime recorded no durable ingest for that stream during the run
+- **THEN** the runtime SHALL stage the cursor without committing it
+
+#### Scenario: A claim backed by durable ingest commits incrementally
+
+- **WHEN** a claim is well-formed, its space matches, and the runtime recorded
+  durable ingest for that stream during the run
+- **THEN** the runtime SHALL commit that stream's cursor without waiting for the
+  run's terminal status
+
+### Requirement: A partition-scoped claim SHALL move only its own partition, and a global floor SHALL be inexpressible
+
+A `checkpoint_claim` MAY declare a partition key. A partition-scoped claim SHALL
+move only the position of the partition it names.
+
+A claim that would move the position of any partition other than the one it
+names SHALL be rejected as a protocol violation.
+
+The claim schema SHALL provide no field by which a connector can assign a
+position to partitions it has not enumerated. A floor inherited by unseen
+partitions SHALL therefore be unrepresentable rather than merely discouraged,
+because such a floor makes every item below it permanently unreachable for a
+partition that was never walked.
+
+#### Scenario: A claim cannot move a partition it does not name
+
+- **WHEN** a partition-scoped claim would advance the position of a different
+  partition
+- **THEN** the runtime SHALL reject the claim as a protocol violation
+
+#### Scenario: An unenumerated partition inherits no position
+
+- **WHEN** a connector has not enumerated a partition
+- **THEN** no claim SHALL assign that partition a position
+- **AND** that partition SHALL remain fully outstanding
+
+### Requirement: A connector whose scan has no order SHALL NOT qualify at any granularity
+
+A connector SHALL NOT emit a `checkpoint_claim` for a stream whose items are
+retrieved without an ordering over the claimed space.
+
+A maximum taken over an arbitrary subset of items SHALL NOT be treated as the
+upper bound of a covered interval. Without an ordering, items below that maximum
+may never have been visited, so an interval claimed up to it asserts coverage
+the connector cannot demonstrate.
+
+Declaring a coarser granularity SHALL NOT qualify an unordered scan. A coarser
+unit asserts completeness over a wider range, so coarsening an unordered scan
+SHALL produce a broader false claim rather than a safer one.
+
+Advancing a watermark only for items actually emitted SHALL NOT by itself
+qualify a stream. Restricting the watermark to emitted items makes it honest
+about which items were counted; it does not establish that the counted items
+form a contiguous prefix of the space.
+
+#### Scenario: An unordered scan is disqualified
+
+- **WHEN** a stream's items are retrieved by a query with no ordering over the
+  claimed space
+- **THEN** that stream SHALL NOT emit a checkpoint claim
+- **AND** it SHALL retain `commit_on_success` behavior
+
+#### Scenario: Coarsening does not rescue an unordered scan
+
+- **WHEN** an unordered stream declares a coarser claim granularity
+- **THEN** it SHALL still be disqualified
+
+#### Scenario: An emitted-only watermark does not establish a prefix
+
+- **WHEN** a stream advances its watermark only over items it emitted, but still
+  retrieves those items without an ordering
+- **THEN** it SHALL remain disqualified
+
+### Requirement: New work on the checkpoint program SHALL preserve ideal compatibility
+
+Changes made under this program SHALL observe the following constraints, so that
+later tranches compose rather than accumulating incompatible mechanisms.
+
+New health logic SHALL NOT be derived by reading evidence projections. Health
+SHALL be derived from the coverage ledger.
+
+New implicit run-state flags SHALL NOT be introduced. Run state SHALL be
+explicit and durable, and SHALL NOT be inferred from the presence or absence of
+a side-channel.
+
+New cursor shapes SHALL NOT violate the claim schema. A new cursor SHALL either
+state a well-formed `checkpoint_claim` or emit no claim at all.
+
+#### Scenario: Health is not re-derived from a projection
+
+- **WHEN** a change introduces health logic under this program
+- **THEN** that logic SHALL read the coverage ledger
+- **AND** it SHALL NOT re-derive health by reading an evidence projection
+
+#### Scenario: Run state stays explicit
+
+- **WHEN** a change under this program needs to record that a run is in some
+  state
+- **THEN** it SHALL record that state explicitly and durably
+- **AND** it SHALL NOT encode it as the presence or absence of an unrelated
+  side-channel
+
+#### Scenario: A new cursor either claims well-formed or stays silent
+
+- **WHEN** a change under this program introduces a new cursor shape
+- **THEN** that cursor SHALL either carry a well-formed `checkpoint_claim` or
+  carry none
+- **AND** it SHALL NOT introduce a third representation of checkpoint safety

+## 1. Establish the qualification standard (this tranche)
+
+- [x] 1.1 Frame the checkpoint contract as a qualification standard rather than
+      a failed design, and state that fleet-wide adoption is not a goal.
+- [x] 1.2 Adopt the covered-intervals representation, with debt derived from the
+      gaps, and specify no storage or compaction layer so the terminal form is
+      an additive migration.
+- [x] 1.3 Define claim granularity and the closed-unit rule, so a connector with
+      a coarse cursor is judged on whether it can prove a coarse unit complete.
+- [x] 1.4 Record the disqualification criteria for unordered scans, including
+      that coarsening does not rescue them and that an emitted-only watermark
+      does not establish a prefix.
+
+## 2. Measure the coarse-granularity question
+
+- [x] 2.1 Re-test `heb` `orders` at day granularity by reading
+      `packages/polyfill-connectors/connectors/heb/index.ts`. Verdict:
+      **qualifies at day granularity, under a closed-day rule**.
+- [x] 2.2 Identify the frontier hazard: `runForwardScan` tracks
+      `newestOrderDate` as a running max (`:901-903`) while orders within a day
+      sort by full timestamp, so the newest day observed may be partially
+      enumerated. Answered by claiming a day only once a strictly older day has
+      been observed.
+- [x] 2.3 Identify the `dateDropped` hazard: an order whose date does not parse
+      is recorded as considered-but-not-covered (`:849-852`) and has no day to
+      be attributed to, so it is a hole of unknown position. Answered by
+      withholding the whole run's claim when `dateDropped` is non-empty.
+- [x] 2.4 Confirm truncation is expressible rather than blocking:
+      `MAX_LIST_PAGES = 50` (`:64`) and `maxPage` exhaustion (`:919-921`) end a
+      walk early, which under covered intervals is simply a smaller covered set.
+- [x] 2.5 Confirm `CHECKPOINT_OVERLAP_DAYS = 60` (`:70`) is a freshness device
+      via `resumeBoundary` (`:1064-1073`), not part of the safety argument.
+- [x] 2.6 Re-confirm `slack` disqualification:
+      `grep -c "ORDER BY" connectors/slack/index.ts` returns `0` on this branch.
+- [x] 2.7 Check whether `fix/slack-emitted-watermark-0821` changes that.
+      It does not: `grep -c "ORDER BY"` on that branch's
+      `connectors/slack/index.ts` also returns `0`. The fix corrects
+      emitted-vs-iterated watermark advance and removes the global-floor
+      `COALESCE`, but adds no ordering.
+
+## 3. Correct the redo-cost statement
+
+- [x] 3.1 Verify by content that no mid-run commit path exists: `newState` is
+      in-memory (`reference-implementation/runtime/index.ts:2762`, assigned at
+      `:4237`) and `commitState` has exactly two call sites (`:5278`, `:5322`),
+      both inside the DONE gate at `:5266`.
+- [x] 3.2 Correct the wording in the research entry
+      `ai/research/pdpp/the-checkpoint-protocol-must-carry-a-proven-boundary-...md`
+      §5, from "work done since the last checkpoint is redone" to redo since the
+      last *committed* cursor.
+- [x] 3.3 Record the correction in this change's `design.md` so the corrected
+      cost-benefit is visible to a reviewer who does not read the corpus.
+- [x] 3.4 Confirm the wording does not appear in any other OpenSpec artifact,
+      branch design note, or research entry.
+
+## 4. Record the ideal-compatibility rule
+
+- [x] 4.1 State the rule in `design.md` with its placement justification.
+- [x] 4.2 Restate it as a requirement in the `polyfill-runtime` spec delta so it
+      survives archival into `openspec/specs/`.
+- [x] 4.3 Decide against `openspec/README.md`: that file is scoped to OpenSpec
+      process, not to program-specific engineering constraints.
+
+## 5. Validation
+
+- [x] 5.1 `openspec validate qualify-connectors-for-incremental-checkpoint-commit --strict`
+      passes.
+- [x] 5.2 `openspec validate --all --strict` shows the same 11 pre-existing
+      failures as the baseline captured before this change, with this change
+      passing.
+
+## 6. Deferred to later tranches
+
+- [ ] 6.1 Add the optional `checkpoint_claim` field to
+      `packages/polyfill-connectors/src/connector-runtime-protocol.ts`.
+- [ ] 6.2 Implement the runtime decision procedure at the `STATE` handler.
+- [ ] 6.3 Claim in `gmail` `messages` first.
+- [ ] 6.4 Owner-authorized live confirmation of the `heb` day-granularity
+      verdict. Deferred here because a `heb` run costs the owner a real OTP, and
+      both rules fail closed so the cost of a misreading is a withheld commit.

+ * Change-feed-is-not-inventory gate.
+ *
+ * CONTRACT UNDER TEST
+ * -------------------
+ * A stream whose manifest declares `coverage_strategy: "full_inventory"` may
+ * NOT prove that claim from a run whose executed code path was an incremental
+ * DELTA. An empty change feed and an empty inventory are different facts, and
+ * only one of them is evidence of anything.
+ *
+ * RFC 6578 §3.2 is normative here and makes this statically decidable: a
+ * sync-collection REPORT carrying an EMPTY `<D:sync-token>` MUST return every
+ * member of the collection, while one carrying a NON-EMPTY token returns only
+ * what changed since that token. So "the response listed 0 resources" means
+ * "0 contacts exist" in the first case and "nothing changed" in the second.
+ *
+ * THE DEFECT THIS PINS
+ * --------------------
+ * Apple Contacts declares `full_inventory` on all three of its streams, but
+ * its steady-state run issues a sync-collection delta. A quiet run therefore
+ * observed 0 changed resources and, before the fix, reported
+ * `considered: 0, covered: 0` — which the coherence oracle reads as a
+ * measured `enumeration_boundary` proving a verified-EMPTY address book. A
+ * required stream holding hundreds of real contacts read Healthy with zero
+ * records.
+ *
+ * The connector now withholds the coverage claim entirely on an incremental
+ * run (`contactsBoundaryEstablished`), leaving the stream honestly unproven
+ * rather than falsely complete. This gate exists so that behavior cannot
+ * silently regress: it drives the REAL connector subprocess against a fake
+ * CardDAV server configured to obey RFC 6578 faithfully, with a prior sync
+ * token in START state, and asserts no fabricated boundary is emitted.
+ *
+ * WHY A CONFORMANCE TEST RATHER THAN A LINT OR A MANIFEST RULE
+ * -----------------------------------------------------------
+ * A manifest-validation rule cannot see which code path executes; it can only
+ * read declarations, and the declaration here (`full_inventory`) is correct —
+ * the address book genuinely is a full inventory. A lint would have to
+ * pattern-match call sites and would be defeated by any indirection.
+ *
+ * The falsifiable fact is behavioral: given a prior token, does the run emit a
+ * coverage boundary it did not measure? Only executing the connector answers
+ * that, and this package already has the machinery to do it cheaply and
+ * credential-free (`_conformance/coverage-conformance.test.ts` drives the same
+ * subprocess against the same fake server). So this extends that pattern
+ * rather than introducing a new mechanism.

+ * `item_count` had no independent source. It was
+ * `Math.max(list.items.length, detail.items.length)` against a non-nullable
+ * `min(0)` schema, so an order whose detail page was never fetched asserted a
+ * confident `item_count: 0` — indistinguishable from a genuinely empty order.
+ *
+ * That mattered because the list card only renders item titles for SMALL
+ * orders; Amazon collapses 3+ item orders behind a "+N more items" affordance
+ * that carries no per-item markup. For those orders the list contributes 0 and
+ * the count rests entirely on the detail page, which the connector defers under
+ * its per-run attempt budget, its temporary-failure cap, or a latched session
+ * repair.
+ *
+ * The live signature is unambiguous: across 1,183 collected orders,
+ * `item_count === 0` never occurs on an order holding 1 or 2 item records, and
+ * occurs on 53 orders holding 3-7 — every one of which also has a null
+ * `shipping_address_summary`, proving the detail page (not the parse) was
+ * missing. Those records claimed an empty order while the database held their
+ * items.
+ *
+ * These tests pin the distinction the old shape could not express: a count of
+ * zero must mean "we looked and there were none", never "we did not look".

+// Recognition of Apple's group vCards, and the `contact_groups` completeness
+// anchor built on it.
+//
+// THE PROBLEM THIS SOLVES
+// -----------------------
+// `contact_groups` is a manifest-REQUIRED stream that has emitted zero
+// records for this owner, ever — including zero tombstones. Two very
+// different worlds produce that same zero:
+//
+//   (a) the address book genuinely has no groups, or
+//   (b) the connector cannot see the groups it has.
+//
+// Until now the connector could not tell them apart, and a required stream
+// sitting at zero for an unfalsifiable reason is exactly the defect this
+// work exists to eliminate.
+//
+// The connector derives groups from the standards-based vCard `CATEGORIES`
+// property (RFC 6350 §6.7.1). That derivation is sound as far as it goes.
+// But Apple/iCloud does not represent groups with CATEGORIES: it stores each
+// group as its OWN vCard resource in the same collection, marked
+// `X-ADDRESSBOOKSERVER-KIND:group`, whose members are listed as
+// `X-ADDRESSBOOKSERVER-MEMBER:urn:uuid:<uid>` lines.
+//
+// So for an iCloud account, (b) was the live behaviour and the connector
+// reported it as (a).
+//
+// THE SECOND, WORSE CONSEQUENCE
+// -----------------------------
+// A group vCard is a real resource in the collection, so the enumeration
+// fetches it and the contact emitter emits it AS A CONTACT — a phantom whose
+// `display_name` is the group's name, counted as a covered contact. Nothing
+// in the emit path checked `KIND`. `isGroupVCard` is what lets the caller
+// keep groups out of `contacts`.
+//
+// THE ANCHOR
+// ----------
+// CardDAV enumerates the collection fully, so the set of resources is
+// measured at the SOURCE boundary. Partitioning that enumerated set by KIND
+// yields a real denominator for `contact_groups`: the number of group vCards
+// the server actually holds. Comparing it against what was emitted turns the
+// unfalsifiable zero into a checkable claim — and a zero that survives the
+// check is now genuine evidence of an empty account rather than an absence
+// of evidence.
+//
+// CEILING, stated honestly
+// ------------------------
+// This anchors groups as iCloud REPRESENTS them. Two group sources are
+// unified here — Apple group vCards and CATEGORIES — and a group expressed
+// only through CATEGORIES on contacts still has no independent server-side
+// resource to count, so its denominator contribution is derived, not
+// measured. `groupAnchor` reports those two populations separately for that
+// reason; it never merges a derived count into the measured one.

  * every in-scope account anyway, so the served account is hydrated by the normal

- * durable `connector_detail_gaps` row moves to `recovered` instead of being

+ * Chase `statements` has the identical shape: a failed PDF download opens a
+ * retryable `DETAIL_GAP` (see `processStatementRow`), and only a later run
+ * that hydrates that statement's PDF again can close it — via
+ * `recoverServedStatementGaps`, mirroring the account-gap path above.
  *
  * These exercise the exported recovery helpers directly through the recording

  *
  * Safety pinned here (lose-no-data):
  *   - only a served gap whose account was reached is recovered;

  *   - a served gap whose account is not enumerated this run is never recovered;
  *   - the recovery gap_id is always the served gap_id, never synthesized;
- *   - only account-level chase.account transaction gaps are recovered — a

+ * ChatGPT conversations declare `message_count_on_current_branch`, and the
+ * obvious reconciliation — compare it against the messages we emitted — proves
+ * nothing. That field is computed by OUR OWN `countBranchMessages` from the
+ * same `mapping` object, inside the same call that emits those messages. Both
+ * sides of that comparison read one in-memory graph, so it is a tautology.
+ *
+ * Worse, it is a tautology that HIDES the real defect. `flattenTreeCurrentBranch`
+ * walks parent pointers and stops silently when a parent is missing from the
+ * mapping. A truncated payload therefore produces a short branch AND a
+ * correspondingly short declared count — the denominator shrinks to match the
+ * loss and the conversation reads complete.
+ *
+ * The provider assertion worth reconciling against is structural: `current_node`
+ * and the `parent` chain declare a branch that must be present and must
+ * terminate at a real root. These tests pin that contract.
+ *
+ * Grounding: reconciled against 5,821 live conversations. On-branch message
+ * counts matched the declared count exactly for 5,815 and never exceeded it,
+ * so equality is the right contract. Three conversations in the historical
+ * archive were short by exactly one message, each with a dangling non-system
+ * parent — the shape `truncatedBranch` reproduces below.

+/**
+ * Reconcile the current branch we walked against the branch the conversation
+ * actually declares, and surface a shortfall as a gap rather than a silent pass.
+ *
+ * The subtlety that shapes this whole check: ChatGPT does NOT hand us an
+ * independent provider total. `message_count_on_current_branch` is computed by
+ * our own `countBranchMessages` from the SAME `mapping` object, in the same
+ * call that emits these messages. Comparing emitted-vs-declared there is a
+ * tautology — both sides read one in-memory graph — so it would prove nothing.
+ *
+ * The real provider assertion is structural: `current_node` plus each node's
+ * `parent` pointer declare a chain, and `flattenTreeCurrentBranch` walks it by
+ * following parents until one is absent from the mapping. That walk STOPS
+ * SILENTLY on a missing parent. A truncated payload therefore yields a short
+ * branch AND a correspondingly short `message_count_on_current_branch` — the
+ * declared count shrinks to match the loss, so the conversation reads complete.
+ * That is the silent-truncation class this check closes.
+ *
+ * So the reconciliation is against the graph's own claims:
+ *   - `current_node` must be present in the mapping. If the tip is absent, the
+ *     branch we walked is not the branch the conversation says it is on.
+ *   - The chain must terminate at a real root (a node with no parent), not at a
+ *     dangling pointer into a node the payload did not include.
+ *
+ * Both are provider-asserted facts measured at the payload boundary, before any
+ * emit decision. Live reconciliation over 5,821 collected conversations:
+ * counting on-branch messages matched the declared count for 5,815 exactly and
+ * NEVER exceeded it, so equality is the right contract and a shortfall is real.
+ *
+ * Emitted as a SKIP_RESULT rather than a DETAIL_GAP for the same reason
+ * `empty_detail` is: the fetch SUCCEEDED and the conversation is genuinely
+ * hydrated. Re-fetching returns the same truncated graph, so a retryable gap
+ * would spin forever. The honest report is "we reached it, and what it gave us
+ * is internally inconsistent".

+ * ── Why no provider-reported total is bound here ──────────────────────────
+ *
+ * GitHub exposes several tempting scalars. Each was measured against this
+ * instance's live holdings and REJECTED. Do not bind them:
+ *
+ *   `public_repos` / `public_gists` (from `/user`, already stored on the
+ *   `user_stats` record) measure a strict SUBSET, not this stream's boundary.
+ *   Live: `public_repos: 94` against 575 held repositories — of which 355 are
+ *   private and 465 belong to orgs, neither of which `public_repos` counts.
+ *   `public_gists: 8` matched the 8 public gists exactly while 43 secret gists
+ *   sat outside it. Binding either would assert a permanent ~6x false gap.
+ *
+ *   `Link: rel="last"` yields a PAGE count, so an item total only under the
+ *   assumption that every page is full — which the last page never is. It also
+ *   cannot survive the deletion semantics below.
+ *
+ *   `total_count` on `/search/issues` IS authoritative for its query, and is
+ *   already consumed for cap-detection (see `PR_SEARCH_RESULT_CAP`). It is not
+ *   promoted to the denominator because a search index is eventually
+ *   consistent with the REST list this stream walks, so a benign index lag
+ *   would read as coverage loss.
+ *
+ * The deeper constraint applies to ALL of them: PDPP deliberately RETAINS
+ * records after the provider deletes them, and GitHub genuinely deletes repos,
+ * issues and gists. A provider total therefore describes the surviving account
+ * and is legitimately SMALLER than what we hold. Any two-way
+ * `provider_total === held_count` check flags successful preservation as a
+ * defect. A sound anchor here would have to be the three-way relation
+ * `provider_total === live_holdings - known_tombstoned`, and this connector
+ * declares no tombstones at all (no `isTombstone`), so the third term is
+ * unavailable and the relation cannot be closed.
+ *
+ * A scalar also cannot distinguish missing from surplus from duplicated. If a
+ * real anchor is wanted later, compare the provider's ID SET against the held
+ * ID set — GitHub returns stable numeric ids on every one of these streams —
+ * and tombstone the upstream-absent ids rather than counting them as loss.

+ * inside the historical walk's remit, or it belongs to neither walk and is
+ * never fetched.
+ *
+ * The old rule was `prior.target_uid ?? priorEnd` — once written, the ceiling
+ * only ever copied itself forward. Meanwhile the forward watermark advanced on
+ * every run with new mail. So the ceiling froze at the mailbox's size on the
+ * day the backfill started while the resume point climbed away from it, and the
+ * interval between them reopened continuously and grew without bound. Repairing
+ * the stored value (as `scripts/repair/gmail-backfill-target-extend.ts` did)
+ * fixed one instance of the gap and not the mechanism: the very next run with
+ * new mail reopened it.
+ *
+ * The rule here instead ties the ceiling to the ONE fact that makes the band
+ * provably empty: the historical walk must own everything up to where the
+ * forward walk genuinely resumes from. `forwardFloorUid` is that point minus
+ * one — the last UID the forward pass will NOT fetch on the next run.
+ *
+ * Why this cannot rewind or thrash
+ * --------------------------------
+ *   - It only ever RAISES: `Math.max` against the prior ceiling. A ceiling that
+ *     could fall would re-open `completed_at` on a finished walk and, worse,
+ *     let `backfilled_through_uid` sit above its own target.
+ *   - It never touches `backfilled_through_uid`. Progress through the mailbox
+ *     (~150k UIDs on the live instance) is preserved exactly; raising a ceiling
+ *     adds `new - old` UIDs of work and re-walks nothing already done.
+ *   - It is bounded per run. The ceiling rises to a watermark the mailbox
+ *     already passed, never to a live `uidnext` that moves while we walk, so
+ *     the walk converges on a fixed target instead of chasing the mailbox

+i.e. that the API contradicted itself in a single response body. That claim
+was never verified. This note records the evidence that refutes it, and what
+the observation actually means.
+
+The reason code is now `history_ended_before_provider_count`, which
+describes what we observed rather than what we concluded about the provider.
+
+## 1. What `count` actually means
+
+`count` is **undocumented**. GroupMe's API reference (dev.groupme.com/docs/v3)
+shows it only inside the sample body for `GET /groups/:id/messages` and never
+defines it in prose. Every available signal says it is the conversation's
+**lifetime total**, not the size of the page just served:
+
+- `GET /groups` returns the same key as `messages.count`, sitting beside
+  `last_message_id` — self-evidently a group total.
+- A per-page reading would make `count` always equal `messages.length`, so the
+  field would carry no information at all.
+- Groupy, the most widely used Python wrapper, binds `count` to a field named
+  `message_count` and returns it from `__len__` — i.e. "how many messages this
+  group has". It re-reads it on every page because the total can drift upward
+  while paginating.
+- No mature client terminates pagination on a `count` comparison. Groupy,
+  `cdzombak/groupme-tools`, and others all terminate on HTTP 304, an empty
+  array, or a short page.
+
+**Therefore an empty page against a non-zero `count` is not a contradiction.**
+The two fields answer different questions: "how many messages has this group
+ever held" versus "what can I serve you from this cursor". A total that
+exceeds what pagination can reach is an ordinary, expected state.
+
+Note also that the two counts in our own code come from **different
+endpoints** and must not be conflated: `pageEndedShortOfProviderCount` reads
+the per-response `count` from `GET /groups/:id/messages`, while the shortfall
+arithmetic uses `providerMessageCount()` from the `/groups` listing.
+
+## 2. The documented terminal page cannot produce a false positive
+
+GroupMe documents: *"If no messages are found (e.g. when filtering with
+`before_id`) we return code 304."* Our `fetchMessagesPage` normalizes that 304
+into a synthetic `{count: 0, messages: []}`. Because the synthetic count is
+zero, `pageEndedShortOfProviderCount` returns `false`, so the documented
+end-of-history signal never trips the shortfall path. The path can only be
+reached by a genuine HTTP 200 carrying a real non-zero `count`.
+
+## 3. What is actually happening: a retention cliff at Aug 2013
+
+Measured against this owner's live Postgres (connector instance
+`cin_5804a2ff36cd303e22762745`, 88,743 stored `group_messages` across 156
+groups):
+
+| bucket | groups | meaning |
+|---|---|---|
+| fully reconciled | 77 | stored count >= provider total |
+| partial | 36 | some messages stored, fewer than the total |
+| zero stored, non-zero total | 42 | nothing stored at all |
+
+Grouping the 156 groups by the year of their last activity (`updated_at`)
+makes the cause unmistakable:
+
+| last active | groups | zero stored | has messages |
+|---|---|---|---|
+| 2011 | 1 | 1 | 0 |
+| 2012 | 31 | 31 | 0 |
+| 2013 | 12 | 10 | 2 |
+| 2014 | 13 | 0 | 13 |
+| 2015 | 20 | 1 | 19 |
+| 2016–2024 | 79 | 0 | 79 |
+
+Every group that went dormant in 2011–2012 stored **zero** messages. Every
+group active from 2014 onward stored messages. This is a temporal cliff, not
+the scattered, load-correlated pattern throttling would produce.
+
+The cliff has an exact date. **The oldest stored message anywhere in this
+account is `2013-08-15T18:08:31.000Z`.** And of the 36 partial groups, all 36
+have their oldest surviving message on or after that date — zero exceptions.
+A group's history is retrievable back to roughly Aug 2013 and no further,
+regardless of which group it is.
+
+Independent corroboration: GroupMe's own API support forum carries a user
+report of paginating `before_id` to a 304 and reaching only ~62k of a reported
+70k messages, with *"Last message it returns is from Aug 2013."* Same wall,
+same date, a different account. The working explanation there was likewise
+server-side retention.
+
+## 4. Scope, and whether the data is recoverable
+
+The production run (`run_1787350099426`, evidence as of
+`2026-08-21T22:11:56Z`) reported **1,601 messages across 42 groups**. Those
+42 groups are exactly the zero-stored set above; all show `walked: 0`.
+
+Independent reconciliation of stored records against the persisted `/groups`
+totals gives a **total shortfall of 6,982 messages across 78 groups** — the
+1,601 figure covers only the 42 zero-stored groups, not the 36 partial ones.
+The affected messages are all pre-Aug-2013.
+
+**Is the owner's data missing?** These messages were never collected, because
+GroupMe would not serve them. They are not lost *by PDPP* — nothing was
+collected and then dropped. Everything GroupMe did serve is stored.
+
+**Is it recoverable?** Almost certainly not through this API. Retrying will
+not help if the messages are no longer stored on GroupMe's side, and the
+evidence strongly indicates that. We nevertheless keep the gap `retryable`
+rather than asserting `not_retriable`, because a single response cannot
+distinguish retention from a transient refusal *per group*, and asserting
+unrecoverability would repeat the original error of converting an ambiguous
+observation into a certain verdict.
+
+## 5. What could not be verified
+
+- **No live API call was made.** The stored credential is sealed, and
+  unsealing owner secrets was out of scope. A single live request against one
+  affected group (e.g. `4747691`, provider count 1, zero stored) would
+  directly confirm the response shape; this note rests on stored artifacts and
+  documentation instead.
+- **No captured raw API response exists.** `/root/.pdpp/fixture-captures/`
+  in `pdpp-core-prod-drain` has no `groupme` directory, so the primary
+  artifact — a recorded body showing `count: N` with `messages: []` — was
+  never captured. The emitted `known_gaps` diagnostics in `spine_events` are
+  the closest available evidence, and they record only our derived
+  per-group `provider_count`/`walked` pairs, not the raw page.
+- **GroupMe's server-side intent for `count` is not provable** from primary
+  sources, because the field is undocumented. The conclusion rests on
+  convergent circumstantial evidence (see §1), which is strong but not
+  certain.

+  The email-first login form, reduced to the elements that drive surface

+  Live shape captured at
+  /root/.pdpp/fixture-captures/heb/raw/2026-08-19T03-18-07-656Z/dom/session-establish-heb-login-form-loaded.html
+  in container `pdpp-core-prod-drain` (url
+  https://accounts.heb.com/interaction/<id>/login, title "My H-E-B Account").
+  The interaction id and the owner's email were replaced with synthetic values.
+
+  This is the surface that made the connector fall through to the unclassified
+  fallback on a perfectly ordinary expired session. H-E-B collects the EMAIL
+  FIRST: only the email input is on screen, next to a "Continue" button, with
+  "Or, log in with a passkey" and "Create one" below it. The password field
+  exists in the DOM the whole time, but it is parked inside
+
+    <fieldset ... class="... overflow-hidden w-0 h-0">
+
+  A `w-0 h-0 overflow-hidden` ancestor has a ZERO bounding box, so Playwright
+  reports the password input — and every other descendant — as NOT VISIBLE.
+  `aria-hidden="true"` and `tabindex="-1"` on the same fieldset say the same
+  thing to the accessibility tree.
+
+  That is the whole defect: `resolveUniqueLoginFormRoot` required exactly one
+  VISIBLE password input inside the form root, counted zero, and refused to call
+  this a login form. The page is unambiguously a login form to any human looking
+  at it.
+
+  Keep the zero-size fieldset exactly as-is. It is not decoration — it IS the
+  regression this fixture pins.

+  The promotional "what's new" interstitial observed over an AUTHENTICATED
+  orders page, reduced to the elements that drive surface classification.
+
+  Live shape captured at
+  /root/.pdpp/fixture-captures/heb/raw/2026-08-19T03-18-07-656Z/dom/runtime-collect-start.html
+  in container `pdpp-core-prod-drain` (url https://www.heb.com/my-account/your-orders,
+  title "Your orders | HEB.com"). Owner name, email, account id, cart, and store
+  were stripped; the promo copy is H-E-B's own marketing text and carries no
+  personal data.
+
+  This is the surface that made the connector ask the owner to sign in when the
+  session was already live. The page underneath is authenticated — `orderResults`
+  is present and populated — but the modal is portaled to <body> OUTSIDE the
+  Next.js root, steals focus, and covers the order content.
+
+  Load-bearing structure, in the order the classifier reads it:
+
+    * The dialog is `[data-component="modal-content"][role="dialog"][aria-modal="true"]`.
+      `data-component` is H-E-B's own component hook; the CSS-module class
+      suffixes (`__o_tcp`) are BUILD HASHES that rotate on every deploy, so they
+      must never be matched.
+    * The close control is `[data-qe-id="modalClose"]` — H-E-B's QA-engineering
+      id, and the most durable dismissal hook on the page. Note its accessible
+      name is "Close Modal", not "Close".
+    * The skin class is `WhatsNewModal_`, a GENERIC announcement slot. Future
+      promos will reuse this chassis with entirely different copy, so nothing
+      here keys on "fastest delivery" or "$9.95".
+
+  The modal is a SIBLING of `[data-qe-id="orderResults"]`, never nested inside
+  it. That is what keeps it structurally distinct from the source-authored empty
+  state (`OrderEmpty_`/`Empty_box` INSIDE `orderResults`) — the two cannot be
+  confused by construction, not merely by ordering.

+// The `order_items` completeness anchor for H-E-B.
+//
+// WHY THIS IS A REAL ANCHOR
+// -------------------------
+// Every H-E-B order card on the list page states its own item count — the
+// "$123.45 · 59 items" line the `LIST_TOTAL_COUNT_RE` parser already reads
+// into `ListPageOrder.itemCount` and stores on the `orders` record as
+// `item_count`. That number is computed by H-E-B, not by this connector, and
+// it is read from the LIST page while the items themselves come from a
+// separate DETAIL page. So comparing them compares two independent source
+// surfaces rather than checking the connector's output against itself.
+//
+// Until now `item_count` was recorded and never checked. Live evidence for
+// why that matters: one instance holds two orders declaring 59 and 85 items,
+// but only 35 and 54 `order_items` records — 89 of 144. Both orders are
+// partially hydrated, and nothing anywhere reported a problem, because
+// nothing compared the two numbers.
+//
+// DELETION-SAFE, ONE-DIRECTIONAL
+// ------------------------------
+// Only "the provider says MORE than we hold" is a gap. Holding more items
+// than the current card states is not loss: H-E-B restates an order's count
+// when items are refunded or removed after fulfilment, and PDPP deliberately
+// preserves the items it already captured. A two-way equality would flag
+// that correct preservation as a defect — the same trap the fleet's other
+// anchors avoid.
+//
+// REFUSES RATHER THAN FABRICATES
+// ------------------------------
+// A missing or malformed `item_count` yields `unavailable`, never zero. A
+// zero denominator would make every order trivially "complete" and would be
+// a denominator invented from the very data it is meant to verify.

+ * `packages/polyfill-connectors/src/collector-definition.ts` for the

+ *
+ * Pure data only — no Node built-ins, no connector runtime imports — so it
+ * stays safe for the publishable `@pdpp/local-collector` build to re-export.
+ *
+ * This connector carries no native COMPILED dependency in the published
+ * npm package itself — it spawns the external `sigtop` binary
+ * (github.com/tbvdm/sigtop, ISC license) as an arms-length subprocess, the
+ * same shape this repo's Slack connector already uses for slackdump and
+ * Google Messages already uses for gmcli. `sigtop` is not bundled/installed
+ * by `@pdpp/local-collector`; it is a separate operator-installed
+ * prerequisite (`go install github.com/tbvdm/sigtop@latest`), resolved via
+ * the `SIGTOP_BIN` env var (default `"sigtop"` on PATH — see index.ts's
+ * `resolveSigtopBin`), documented in the manifest's
+ * `runtime_requirements.external_tools` entry.
+ *
+ * Unlike claude_code/codex/google_messages, this connector declares no
+ * `coverage_diagnostics` stream: each stream carries its own manifest
+ * `coverage_strategy` (`snapshot_import_receipt` / `parent_detail_accounting`),
+ * the same per-stream coverage mechanism imessage uses for an identical
+ * reason (see imessage/collector-definition.ts's module doc).

+ *
+ *  2. `parseEmittedIds` / `mergeEmittedIds` — the durable emitted-id cursor

+ *     set is the whole point: a scalar count of the same facts is a
+ *     tautology (`sourceTotal - belowWatermark` IS the in-window row count
+ *     when both are read from one database in one instant), and it also
+ *     cannot tell an upstream deletion from a real gap. PDPP retains

+ * PDPP Signal Desktop Connector (v0.1.0)
+ *
+ * Reads Signal Desktop's local encrypted `db.sqlite` through the `sigtop`
+ * sidecar CLI (github.com/tbvdm/sigtop, ISC license) rather than a native
+ * SQLCipher binding: Signal's DB key is protected by Electron's
+ * `safeStorage` (OS-keychain-backed AES/PBKDF2 unwrap — KWallet/libsecret
+ * on Linux, Keychain on macOS, DPAPI on Windows), and sigtop already
+ * implements that unwrap correctly across all three platforms. This is the
+ * same "arms-length subprocess" pattern the `slack` connector uses for its
+ * own Go sidecar tool — a Go binary kept at a distance rather than
+ * reimplemented or natively bound.
+ *
+ * `sigtop` binary resolution: `SIGTOP_BIN` env var, default `"sigtop"` on
+ * PATH — mirrors the analogous `*_BIN`/`resolve*Bin` pattern the `slack`
+ * connector uses for its own sidecar. Install:
+ * `go install github.com/tbvdm/sigtop@latest` (Linux additionally needs
+ * `libsecret-1-dev` + `pkg-config` at build time; see sigtop's README).
+ *
+ * ## sigtop CLI mechanics (verified directly against sigtop's Go source,
+ * github.com/tbvdm/sigtop — a prior design pass assumed `query-database`
+ * writes a SQLite file; it does not, and that assumption is corrected
+ * here):
+ *
+ *   - `sigtop check-database` — fast-fail health check (SQLCipher
+ *     cipher_integrity_check / integrity_check / foreign_key_check
+ *     pragmas). Non-zero exit + failure lines on stdout when the DB fails
+ *     a check.
+ *   - `sigtop query-database [-o outfile] sql` — writes each result row as
+ *     UNESCAPED pipe-delimited text (`strings.Join(columns, "|")`, one
+ *     line per row) to `outfile` or stdout. There is no quoting: a column
+ *     value containing a literal `|` (e.g. a message body) makes the row
+ *     ambiguous to re-split. This connector therefore does NOT use

+ *   - `sigtop export-database [-B] [-d dir] file` — decrypts the FULL

+ *     `file` is a positional argument, not `-o`, and sigtop opens it with
+ *     `O_EXCL` (fails if it already exists) — this connector always
+ *     targets a freshly `mkdtemp`'d path it never pre-creates. This is
+ *     the connector's PRIMARY data-access mechanism for `messages`,
+ *     `conversations`, and `reactions`: opened read-only with
+ *     `node:sqlite`'s `DatabaseSync`, queried with real bound `?`
+ *     parameters (no manual SQL-string interpolation of the cursor value
+ *     — `node:sqlite` supports positional bound parameters the same way
+ *     `imessage`/`slack` already use them). One export, shared across all
+ *     three streams, deleted at the end of the run.
+ *   - `sigtop export-attachments -i <dir>` — real incremental support
+ *     native to the tool: a `.incremental` marker file in `<dir>` skips
+ *     attachments already exported by a prior run. Attachment BYTES are
+ *     encrypted at rest by Signal Desktop itself (a per-attachment
+ *     `localKey`); only sigtop knows how to decrypt them, so this
+ *     connector never reads Signal's raw `attachments.noindex/` tree
+ *     directly — it always goes through this export step first, then
+ *     hydrates from sigtop's own (connector-controlled) decrypted output
+ *     directory using the exact same TOCTOU-safe O_NOFOLLOW read
+ *     primitive (`readAttachmentFileSync`, `resolveSafeAttachmentPath`)
+ *     `imessage/index.ts` uses against its own Attachments tree — same
+ *     threat model (untrusted path from a local tool's output, trusted
+ *     root directory, check-then-read race), so it is imported rather
+ *     than re-derived.
+ *
+ * Signal Desktop's own schema exposes `hasAttachments`/edit-history/
+ * reactions only inside each message row's `json` TEXT column, not as
+ * flat SQL columns (verified against sigtop's own
+ * signal/{message,reaction,attachment}.go, which parses that same JSON
+ * envelope for its own text/JSON export formats). `parsers.ts`'s
+ * `parseMessageJson`/`extractReactionsFromMessageJson` decode exactly that
+ * shape; this connector has no CLI subcommand that emits per-message
+ * reaction or attachment-presence data as a flat row, so both are derived
+ * here rather than queried directly.
+ *
+ * Per-attachment metadata (content_type, size, owning message id) comes
+ * from Signal Desktop's `message_attachments` table (schema version >=
+ * 1360 only — see sigtop's signal/attachment.go), read from the same
+ * export-database SQLite file already opened for messages/conversations/
+ * reactions. On an older schema lacking that table, attachments still
+ * hydrate (bytes + hash) but message_id/content_type degrade to
+ * best-effort/null rather than the run failing — the same
+ * `tableExists`-gated schema-drift tolerance imessage applies to its own
+ * optional tables.
+ *
+ * Complexity budget: this connector deliberately does NOT copy slack's
+ * stall-vs-runtime-timeout budgets, sqlite-lock-race retry counts, scoped-
+ * archive reconciliation, or 3-way resumed/failed/throttled outcome
+ * machinery — all of that was earned by specific production incidents
+ * that have no analog here yet (see slack/index.ts's own module doc for
+ * that history). This connector starts at imessage's complexity budget:
+ * one subprocess call per concern, a plain incremental cursor,
+ * schema-drift tolerance via `tableExists`. Additional complexity is
+ * warranted only by a real observed failure, not preemptively.
+ *
+ * Reachability probe and mock-mutation check are permanently and
+ * correctly UNKNOWN for this connector: it has no network surface at all
+ * (a local subprocess reading a local file), the same shape as
+ * imessage/claude_code/whatsapp. That is not a gap the checklist expects
+ * closed — see CONNECTOR-CHECKLIST.md's exemption rule and this repo's
+ * docs/inbox/report-connector-coverage.md classification table.
+ *
+ * Target evidence level: Development — real collector, unverified against
+ * a live account (CONNECTOR-CHECKLIST.md). No cross-platform testing claim
+ * is made anywhere in this connector or its tests: sigtop's own docs and
+ * source state the same subcommands/flags behave identically across
+ * Linux/macOS/Windows, but only a Linux run (unit tests + a mocked
+ * subprocess integration test) has actually been exercised while building
+ * this — no real sigtop binary, no real Signal account, no macOS/Windows

+ *
+ * Shape notes:
+ *   - `messages.id` / `conversations.id` are Signal's own row UUIDs —
+ *     regex-constrained, unlike iMessage's permissive GUID-or-ROWID string
+ *     (Signal's schema always carries a real UUID primary key, no numeric
+ *     ROWID fallback).
+ *   - `sender` (messages.sender, reactions.sender) is bounded free text, NOT
+ *     assumed UUID-shaped: verified against sigtop's own source
+ *     (signal/reaction.go's `recipientFromReactionID`), Signal Desktop's
+ *     schema has carried a phone-number-prefixed id, a bare legacy
+ *     conversation id, or a service-id UUID depending on schema version and
+ *     record age — treating it as a UUID would silently skip real historical
+ *     data from an older account.
+ *   - `body` is free-form message text → pdppSafeText.
+ *   - `sent_at` is always a real ISO string derived from the row's own
+ *     epoch-ms value; a row with no usable timestamp is never emitted
+ *     (index.ts skips it with a SKIP_RESULT instead of substituting the run
+ *     clock — same discipline as imessage's `date`).
+ *   - `type` is Signal's own message-type string (e.g. "incoming",
+ *     "outgoing", "call-history") — open vocabulary, so pdppSafeText rather
+ *     than a closed enum (Signal Desktop exposes it as free text, and new
+ *     Signal message types have shipped over time).
+ *   - `attachments.id` is a sha256 of the exported attachment's local path
+ *     (never the raw path itself) — same never-leak-a-local-path invariant
+ *     as imessage's attachments.id.

+ *     only per-channel completeness fact slackdump exposes; there is no

+ *     from surplus from duplicated, and — because PDPP retains records the
+ *     source later deletes — a channel we hold history for that Slack no
+ *     longer lists must never read as loss.
+ *
+ *  2. `emitMessagesPass`'s `covered` — previously the message family
+ *     declared `covered: considered` unconditionally, so the coverage
+ *     number could not fail. It is now counted per-row from the parse
+ *     outcome: a row whose Slack `ts` will not parse gets a fabricated

+ * The Slack cursor invariant: a durable watermark records what was EMITTED,

+ *
+ * The two ways a walked row can fail to be emitted, both covered here:
+ *
+ *   1. The run is channel-scoped, so `emitMessageRecordScopedByChannel`
+ *      drops rows for channels outside the scope. A scoped run reads the
+ *      whole BASE archive, so it walks rows for every other channel in the
+ *      workspace on its way past.
+ *   2. The `messages` stream is not requested at all (a reactions-only or
+ *      attachments-only run still co-traverses the same MESSAGE rows).
+ *
+ * Plus the query-side half of the same rule: a channel with no committed

+ * Proves the scoped-archive message-family DETAIL_COVERAGE duplication bug
+ * (production: 8 Slack runs, 0 successes — see
+ * openspec/changes/fix-slack-scoped-archive-coverage-duplication).
+ *
+ * `reconcileMessageSourceCache` heals a base archive missing channels a prior
+ * run observed by pulling each missing channel's existing scoped archive
+ * (archive-scoped/<digest>/) — see the single-scoped-archive case in
+ * archive-reclaim.test.ts. When 2+ DISTINCT scoped archives are needed (each
+ * covering a different missing channel — production sees 3),
+ * `mergeScopedMessageArchivePasses`'s `for (const archive of
+ * deps.scopedArchives)` loop calls `runRequestedStreams` once per archive.
+ *
+ * Before the fix, `runRequestedStreams` itself emitted the messages
+ * self-coverage DETAIL_COVERAGE (state_stream=messages, stream=messages) on
+ * EVERY call — so N archives meant N emissions of the pair through the same
+ * emit side-channel.
+ * reference-implementation/runtime/index.ts's `trackDetailCoverage` rejects
+ * any repeated (state_stream, stream) pair ("Connector emitted duplicate
+ * DETAIL_COVERAGE for state_stream=messages stream=messages"), so a
+ * production run touching 2+ scoped archives never completed.
+ *
+ * This test seeds a base archive missing TWO channels, each recoverable from
+ * its own separate pre-existing scoped archive, drives the real connector
+ * (PDPP_SLACK_SKIP_SLACKDUMP=1 — no real slackdump subprocess) via
+ * `runConnectorProtocolSubprocess`, and asserts on the RAW emitted message
+ * sequence: each (state_stream, stream) DETAIL_COVERAGE pair must appear
+ * EXACTLY ONCE, with `considered` equal to the summed row count across the
+ * base archive + both scoped archives (mergeMessagesPassResults sums
+ * `considered`).

+// The `transactions` completeness anchor for USAA checking statements.
+//
+// WHY THIS IS A REAL ANCHOR, not a derived denominator
+// ----------------------------------------------------
+// Every other completeness signal in this connector counts what the run
+// itself produced, so it can only ever prove "no gap I could detect". A USAA
+// checking statement prints two numbers the bank computed on its own side:
+//
+//     Beginning Balance $38,586.78
+//     Ending Balance    $33,821.48
+//
+// Those are period totals of record. If the transactions parsed for that
+// period sum to exactly `ending - beginning`, the statement itself has
+// certified that the set is complete — a missing or duplicated transaction
+// changes the sum and the identity fails. That is a provider-side proof, and
+// it is measured at the source boundary (the PDF text USAA rendered), not
+// derived from what this connector chose to emit.
+//
+// The relation is deliberately an EQUALITY over signed cents:
+//
+//     ending − beginning == Σ(transaction amounts)
+//
+// It is not a count and not a coverage ratio, so it is immune to the trap
+// that a shortfall check falls into: it detects a transaction we invented
+// just as surely as one we lost.
+//
+// WHY THIS IS NOT SUBSTITUTED AS `considered`
+// -------------------------------------------
+// The runtime admits a bounded page only when `considered === covered`
+// (reference-implementation/server/continuation-proof.ts). Substituting a
+// statement-level total as a per-page `considered` would make every run read
+// `partial` forever. This module therefore returns a stream-level VERDICT
+// about a period, never a page denominator. The caller reports it as its own
+// fact; it does not feed the page arithmetic.
+//
+// CEILING, stated honestly
+// ------------------------
+// This proves completeness only for periods USAA published as a checking
+// statement AND whose PDF this connector holds. It says nothing about the
+// current, unstatemented cycle, and nothing about credit-card statements,
+// whose era prints no running-balance column (see `extractPeriodBalances`,
+// which returns null rather than guessing). A period with no statement is
+// simply unanchored — this module reports that as `unavailable`, never as
+// proof of completeness.

+/**
+ * YNAB's coverage proof is deletion-safe.
+ *
+ * PDPP deliberately RETAINS records after the provider deletes them, so any
+ * completeness check that compares a provider total against a held count will
+ * flag successful preservation as loss. YNAB avoids that trap by construction,
+ * and these tests pin the two properties that make it work:
+ *
+ *   1. A deleted row arrives IN-BAND. YNAB's delta marks a deletion as a
+ *      returned record with `deleted: true` rather than by omitting it, so the
+ *      row is inside the enumerated boundary: it raises `considered`, is
+ *      validated like any other row, and raises `covered` too. A deletion is
+ *      therefore NOT a coverage gap — it is a covered fact about a deletion.
+ *      (The runtime turns it into a tombstone via this connector's
+ *      `isTombstone: (_stream, d) => d.deleted === true`.)
+ *
+ *   2. A malformed row still degrades coverage. `covered` is tallied per record
+ *      from the same `validateRecord` verdict the runtime's emitRecord applies,
+ *      never aliased to the response length, so a row that cannot be emitted is
+ *      considered-but-not-covered and reads a real `partial`.
+ *
+ * Verified against live data when this was written: this instance holds 9 YNAB
+ * tombstones (4 payees, 5 transactions) with distinct `deleted_at` timestamps
+ * across several runs — the in-band deletion signal reaches durable storage.
+ * YNAB holds 9 of the fleet's 11 tombstones.

+ * Bans direct `process.env.<CONNECTOR>_USERNAME` / `_PASSWORD` credential
+ * reads in connector code.
+ *
+ * ## Why
+ *
+ * A connector's sign-in credentials must come from the `credentials` object
+ * the runtime resolves for THIS run's connection and threads into
+ * `ensureSession` (see `src/auto-login/login-credentials.ts` for the full
+ * rationale). Reading `process.env` directly reaches the same value in the
+ * happy case — the reference server injects the connection-scoped fragment
+ * into the child's environment — but it silently discards everything the
+ * runtime built around the declared path:
+ *
+ *   - a connector that reads `process.env` has no reason to declare an `auth`
+ *     block, and four did not (`heb`, `chase`, `amazon`, `chatgpt`), so the
+ *     runtime resolved `{}` and never raised the `credentials` INTERACTION
+ *     that would have told the owner a credential was expected;
+ *   - an absent value falls through to a generic "hand the page to the owner"
+ *     branch whose message blames the PAGE, not the credential.
+ *
+ * The result was a run that bailed to manual sign-in within seconds and gave
+ * the owner a misleading reason, indefinitely.
+ *
+ * ## What this enforces
+ *
+ * Under `src/auto-login/` and `connectors/`, a credential-shaped
+ * `process.env` read is an error. Use `resolveLoginCredentials(credentials,
+ * …)` instead. Files still carrying the old shape are listed in
+ * `MIGRATION_ALLOWLIST` with the connector that owns them; the list may only
+ * shrink. A file that leaves the list can never silently rejoin it, and a NEW
+ * file can never be added to it without an explicit edit here — which is what
+ * makes the wrong thing hard to do rather than merely discouraged.
+ *
+ * Test files are exempt: they legitimately set and restore these variables to
+ * drive the very fallbacks being migrated away from.

+ * The one resolution path for a browser connector's sign-in credentials.
+ *
+ * ## Why this module exists
+ *
+ * A browser connector needs a username/password to drive a provider's own
+ * sign-in form. There have historically been two ways to obtain them, and only
+ * one of them is correct:
+ *
+ *  1. **`ctx.credentials`** — the runtime resolves the connector's declared
+ *     `auth` block (`connector-runtime.ts`'s `resolveCredentials` →
+ *     `@pdpp/connector-protocol/auth`) and threads the result through
+ *     `establishSession` into `ensureSession({ credentials })`. When a
+ *     credential is missing the runtime raises a `credentials` INTERACTION
+ *     naming exactly which fields it needs, and the owner can supply them.
+ *
+ *  2. **`process.env.<CONNECTOR>_USERNAME`** read inside `ensureSession` — the
+ *     shape `heb`, `chase`, `amazon`, `chatgpt`, `github`, and `reddit` used.
+ *
+ * Path 2 reaches the same values in the happy case, because the reference
+ * server injects the connection-scoped fragment into the CHILD process env (see
+ * `static-secret-injection.ts` and `runtime/connector-child-environment.ts` —
+ * the child does NOT inherit the parent's environment, so a connector's
+ * `process.env.HEB_USERNAME` is that one connection's secret, not a
+ * process-global one). Path 2 is therefore not a security leak and not a
+ * multi-account defect at the injection layer.
+ *
+ * What path 2 loses is everything the runtime built around path 1:
+ *
+ *  - **No declared `auth` block.** A connector that reads `process.env`
+ *    directly has no reason to declare `auth`, and four of them
+ *    (`heb`, `chase`, `amazon`, `chatgpt`) did not. With no declaration the
+ *    runtime resolves `{}`, never prompts for the missing field, and never
+ *    tells anyone a credential was expected.
+ *  - **No precise failure.** When the value is absent the connector falls
+ *    through to a generic "hand the page to the owner" branch whose message
+ *    describes the PAGE ("sign-in form did not render", "unexpected UI"), not
+ *    the CREDENTIAL. The owner is told the site broke when the truth is that
+ *    no stored credential reached the run.
+ *  - **No way to notice.** Nothing fails; the run just quietly asks for manual
+ *    help within seconds, forever.
+ *
+ * This module makes path 1 the only path. `resolveLoginCredentials` takes the
+ * `credentials` object the runtime already hands `ensureSession` and returns
+ * either a complete credential pair or a typed, *specific* absence. The
+ * companion lint gate (`scripts/check-no-direct-credential-env.ts`) makes path
+ * 2 unrepresentable: reading `process.env.*_USERNAME` / `*_PASSWORD` anywhere
+ * under `src/auto-login/` or `connectors/` fails the build.
+ *
+ * ## Multi-account
+ *
+ * Nothing here reads ambient state. The values come from the `credentials`
+ * argument, which the runtime derived from THIS run's connection. Two
+ * connections of the same connector therefore resolve two different pairs —
+ * the case a process-global env var structurally cannot express.

+ * Drift guard: `venmo.json`'s `capabilities.declared_reason_tokens` must equal
+ * `VENMO_DECLARED_REASON_TOKENS`, the constant Venmo's own throw sites are
+ * built from.
+ *
+ * WHY THIS TEST LIVES HERE AND NOT IN THE RI
+ * ------------------------------------------
+ * These two lists are the same fact written twice: the manifest is what the
+ * RI reads at run time (`runtime/declared-reason-tokens.ts`), and the
+ * constant is what the connector actually throws. If they drift, the symptom
+ * is silent — the RI keeps redacting a real fault-class name and the owner
+ * sees `[REDACTED]` again, which is exactly production `run_1787101857760`.
+ *
+ * Drift detection belongs next to the source of truth. The RI cannot own this
+ * check: doing so would mean RI production or test code importing
+ * `src/auto-login/venmo.ts` and naming a connector, the precise
+ * zero-connector-knowledge violation that moving these tokens into the
+ * manifest removed. Here, both sides are in-package and importing the real
+ * constant is free.
+ *
+ * The RI's half of the contract — that a declared token survives redaction
+ * and an undeclared connector is byte-identical to prior behavior — is tested
+ * against synthetic manifests in
+ * `reference-implementation/test/venmo-declared-reason-tokens-survive-redaction.test.ts`.

+// BOTH inputs at once —
+//
+//   {t: INPUT, ty: password, n: "",            dis: false, vis: true}
+//   {t: INPUT, ty: email,    n: "login_email",  dis: false, vis: true}
+//
+// The password field is UNNAMED. `makeTwoStepVenmoPage` models the password
+// field as matching `input[name="password"]`, so its step-one screen answers
+// "not visible" to every PASSWORD_SELECTOR read. The real page does not: the
+// unnamed field matches PASSWORD_SELECTOR's third alternative,
+// `input[type="password"]`, on screen ONE.
+//
+// That difference is the whole defect. `fillVenmoPassword` opens with
+//
+//   if (await locatorIsVisible(page.locator(PASSWORD_SELECTOR).first())) {
+//     await passwordIn.fill(password); return null;   // "one-screen form"
+//   }
+//
+// so against the real page it types the password into the step-one form and
+// returns WITHOUT clicking `Next`. `loginWithSavedCredentials` then treats that
+// as "password filled, ready to submit", clicks the only control present
+// (`Next`), and thereby submits the IDENTIFIER alone. Venmo stays on step one,
+// the post-submit probe reads dead, and the run hands off at venmo.ts:1010 with
+// "automated sign-in did not complete" — the post_submit copy — even though no
+// password was ever submitted.
+//
+// This reproduces production `run_1787319714987`: run.started 13:41:55.098,
+// interaction_required 13:42:00.620. Five seconds, because NO bounded wait is
+// ever entered — the password branch short-circuits immediately and every other
+// step is a fast DOM read. The owner's screenshot at handoff showed a pristine
+// "Log in / Enter email, mobile, or username / Next / Sign up" screen, which is
+// exactly step one, consistent with the identifier having been submitted into

+ * Fleet-wide build-time guardrail: no connector may emit a DETAIL_COVERAGE for
+ * a stream its own manifest declares with a static `state_stream` parent.
+ *
+ * Such a stream is a static single-parent detail stream: its checkpoint status
+ * is projected from the declared parent's own commit outcome, so the runtime's
+ * `validateDetailCoverageAgainstManifest`
+ * (reference-implementation/runtime/index.ts) throws on the emission and fails
+ * the ENTIRE run with `runtime_error`. A detail stream inheriting its parent's
+ * considered/covered is also asserting a denominator it never earned — the
+ * `covered == considered` fabrication this codebase has worked to eliminate.
+ *
+ * Regression this exists to prevent: commit 160d78c26 added the runtime guard
+ * AND connector code violating it, in the same tree. It stayed latent for six
+ * days because the guard was not deployed. The moment deploy drain29 shipped
+ * it, EVERY run of both violating connectors (gmail `message_bodies`, slack
+ * `reactions` + `message_attachments`) began failing with `runtime_error` — a
+ * total collection outage, forcing a rollback to drain28. Per-connector tests
+ * could not catch this class: each connector's own suite was green, and no
+ * test read the fleet as a whole.
+ *
+ * This test is deliberately STATIC (manifest + source text) rather than
+ * behavioral. A behavioral fleet test would have to execute all 45 connectors
+ * against live credentials; a static one covers every connector including
+ * OTP/owner-gated ones (heb, usaa, chase, amazon, venmo, reddit) that cannot
+ * be driven in CI, and covers a stream the day the manifest declares it.
+ *
+ * It is intentionally CONTRACT-based, not name-based: the manifests are the
+ * authority on which streams are state_stream-parented, so a newly-parented
+ * stream is covered automatically without editing this file.

It does NOT erase a running collection: a connection with an in-flight run is REFUSED, not deleted (no active-run row is erased while running). The source-of-truth deletion (records, history, version counters, blobs, blob bindings, attention, schedule, device back-ref, and the connector_instances row) is transactional all-or-nothing across one connector_instance_id; the search-index teardown is a rebuildable projection cleaned up after that commit.

+ * Boot-time record-attribution consistency check.
+ *
+ * Standing principle P1: no data known to the system may be invisible in the
+ * UI. Every read surface the owner has — the Sources list, Explore's
+ * connection facets, Add Source — enumerates connections from
+ * `connector_instances` and then reads records scoped by
+ * `connector_instance_id`. A live (`NOT deleted`) record whose
+ * `connector_instance_id` has NO `connector_instances` row is therefore
+ * unreachable from every one of those surfaces: nothing enumerates it, so
+ * nothing can scope a record read to it. It is not deleted, not archived, and
+ * not shown — it is silently stranded.
+ *
+ * This module does not repair that state; repair is a data decision the owner
+ * must approve. It makes the state LOUD at boot, because the alternative the
+ * owner rejected is silence: a restart that leaves the system inconsistent
+ * while reporting nothing.
+ *
+ * Deliberately read-only. It runs `SELECT`s and returns a summary. It never
+ * deletes, reassociates, or mutates a record — so it is safe to run on every
+ * boot, before HTTP routes mount, on a database whose disposition has not yet
+ * been decided.
+ *
+ * Note on `connector_summary_evidence` pruning: the evidence engine's
+ * `pruneOrphanedEvidenceComplete` deletes the summary-evidence row for an
+ * instance that no longer exists. That prune touches only
+ * `connector_summary_evidence` — never `records` — so it cannot destroy the
+ * owner's data. It does, however, remove the last *derived* trace of the
+ * stranded instance, which is precisely why the underlying `records` rows
+ * need this independent check rather than relying on evidence surviving.

The `paused`-status sibling of `ownerReactivateConnection`: flips the connection from `paused` back to `active` so it becomes runnable again. Already-collected records, grants, schedule, and audit spine are untouched (zero cascade). Resume does not itself validate or supply a credential — repair the credential first (e.g. via the static-secret credential-capture route, which admits a `paused` target) if the connection needs one; a resumed connection with a missing/invalid credential surfaces a typed credential error on its next collection run. A non-paused (active/draft/revoked) connection returns `connector_instance_not_paused` (409). A foreign/unknown id returns `connector_instance_not_found` (404).

The inverse of `ownerResumeConnection`: flips the connection from `active` to `paused` so no future scheduled or manual run lands for it. Already-collected records, grants, schedule, the stored credential, and the audit spine are untouched (zero cascade) — pause is the reversible 'stop collecting for now, keep everything' act, distinct from revoke, which is the durable end of an account relationship. Resume it with `ownerResumeConnection`. A non-active (already-paused/draft/revoked) connection returns `connector_instance_not_active` (409). A foreign/unknown id returns `connector_instance_not_found` (404). Owner bearers only; client/mcp_package grants SHALL NOT reach this route.",

+ * Cursor-band contiguity — the one completeness check that needs no provider
+ * call, no timestamps, and no second copy of the data.
+ *
+ * THE INVARIANT
+ * -------------
+ * When a stream walks ONE ordered identifier space with TWO independent
+ * pointers — a historical pass climbing toward a frozen ceiling, and a forward
+ * pass resuming from a watermark — the two walked intervals must MEET. If the
+ * ceiling stops below where the forward pass resumes, the identifiers between
+ * them belong to neither walk and are never fetched:
+ *
+ *     ID:  1 .......... ceiling | ORPHANED BAND | resume ....... *
+ *          \___ historical ____/                 \___ forward __/
+ *
+ * Formally, for a two-pointer stream: `ceiling + 1 >= resume`.
+ *
+ * WHY NO EXISTING GATE CAUGHT THIS
+ * --------------------------------
+ * Every coverage signal in this codebase compares `covered` against
+ * `considered` — "did I process what I fetched". That equality holds
+ * throughout an orphaned band, because the connector genuinely did process
+ * everything it fetched. It simply never fetched the band. Contiguity is a
+ * statement about the FETCH PLAN, not about processing, which is why it is
+ * the only local check that can see this class of loss.
+ *
+ * On the live instance the Gmail `messages` cursor sat at
+ * `target_uid: 323723` / `forward_uidnext: 324021`, so `323724 >= 324021` was
+ * false and a 297-UID band — two days of mail — was unreachable. This check
+ * evaluates to `violated` on exactly that state.
+ *
+ * WHO DECLARES, AND WHO OWNS THE SEMANTICS
+ * ----------------------------------------
+ * A stream opts in by declaring a CLOSED enum in its manifest:
+ *
+ *     "cursor_shape": "imap_uid_band"
+ *
+ * That declaration carries exactly one bit of connector fact — "this stream's
+ * cursor is a two-pointer walk of an IMAP UID space" — which only the
+ * connector can know. Everything else below (which paths hold the ceiling and
+ * the resume pointer, the `UIDVALIDITY` epoch guard, the `ceiling + 1 >=
+ * resume` arithmetic) is IMAP-specific RI logic and stays RI-owned, keyed off
+ * the declared enum. The manifest selects a variant; it never supplies the
+ * formula.
+ *
+ * That split is the point. If the manifest carried the PATHS, a connector
+ * could mis-path its own ceiling and quietly turn a real violation into
+ * `incomplete_cursor` silence — the audited party would be defining the
+ * audit. Because the enum is closed, an unrecognized value selects no variant
+ * and yields `not_registered`, and declaring can only opt a connector IN:
+ * omission yields `not_applicable`/`not_registered`, which is never reported
+ * as healthy. The failure mode of a bad declaration is a check that does not
+ * run, never a check that lies.
+ *
+ * Precedent: manifests already declare `cursor_field`, and
+ * `capabilities.refresh_policy.max_recovery_attempts` uses the same "manifest
+ * declares, RI clamps" shape.
+ *
+ * SCOPE: WHY ONLY THE IMAP UID BAND TODAY
+ * ---------------------------------------
+ * A fleet-wide survey of every persisted cursor shape (44 connectors, and the
+ * live `connector_state` table) found that gmail `messages` is the ONLY stream
+ * that keeps two pointers over one ordered space — hence exactly one variant
+ * below. The others are:
+ *
+ *   - single-watermark (github, reddit, notion, spotify, strava, venmo, oura,
+ *     imessage, signal, chatgpt, twitter_archive) — one pointer cannot form a
+ *     band; there is nothing to check.
+ *   - per-partition-map (amazon `years`, chase `per_account`, claude-code /
+ *     codex `file_cursors`, slack `channel_last_ts`, groupme `cursors`) — each
+ *     partition carries its OWN independent pointer over its OWN space. Two
+ *     partitions are not two pointers over one space, and comparing across
+ *     them would be meaningless. Amazon's `frozen` flag is a per-partition
+ *     terminal marker, not a ceiling.
+ *   - opaque-token (apple_contacts `sync_token`, google_calendar per-calendar
+ *     `sync_token`, ynab `server_knowledge`) — the values are not ordered and
+ *     not comparable by us at all; arithmetic on them is undefined.
+ *   - gmail `attachments` — a backfill FLOOR (`backfilled_through_uid`) with
+ *     no ceiling and no forward pointer. One-sided, so no band exists.
+ *
+ * Declaring any of those would produce a check that fires on correct
+ * behavior, which is worse than no check. The variant table below is
+ * therefore deliberately narrow and explicit rather than shape-sniffing: a
+ * heuristic that guessed "two numbers in a cursor = a band" would fire on
+ * `pacing_interval_ms`/`pacing_recorded_at_ms` and on gmail's own
+ * `uidnext`/`highest_modseq`, none of which bracket a band.
+ *
+ * WHAT A VIOLATION MEANS, AND WHAT IT DOES NOT
+ * --------------------------------------------
+ * A violation is a POSITIVE, self-evident defect signal, not an "unproven"
+ * — unlike a coverage claim, it needs no upstream cooperation to interpret.
+ * The two stored numbers alone prove the fetch plan skips an interval; no
+ * provider fact could make `323724 >= 324021` true. That is why this check
+ * reports `violated` rather than withholding a healthy verdict: withholding
+ * would understate a defect we can actually prove.
+ *
+ * Conversely, `not_applicable` (no registered band, or the cursor has not yet
+ * written both pointers) is NEVER reported as healthy or as a violation. An
+ * absent pointer means the walk has not started, which is not evidence of a
+ * gap. This is the same honesty rule the coverage oracle applies: silence,
+ * not a manufactured verdict.
+ *
+ * UIDVALIDITY GUARD
+ * -----------------
+ * IMAP's `UIDVALIDITY` (RFC 9051 §2.3.1.1) is the canonical signal that an
+ * identifier space has been reset — every stored UID becomes meaningless.
+ * When the two pointers were recorded under DIFFERENT `uidvalidity` epochs
+ * they are not points in one ordered space and the subtraction is not
+ * defined, so the comparison is refused (`epoch_mismatch`) rather than
+ * producing an arithmetic answer over incomparable numbers.
+ */
+
+/**
+ * The closed set of cursor shapes a manifest may declare via a stream's

+ * Declared-reason-token lookup — the ONE place the RS-side runtime
+ * (`connector-gap-bounding.ts`'s `boundConnectorErrorMessage`) reads which
+ * >=24-char snake_case tokens a connector's own thrown-error vocabulary is
+ * allowed to keep verbatim through `stderr-redact.ts`'s `LONG_OPAQUE_RE`
+ * entropy heuristic.
+ *
+ * Why this exists: `runtime/stderr-redact.ts`'s `declaredReasonTokens`
+ * mechanism (added for a 2026-08-18 HEB incident —
+ * `heb_session_failed: [REDACTED]`) was wired into `run-logger.ts` (internal
+ * scheduler/executor logging) but never into `boundConnectorErrorMessage`,
+ * the function that actually redacts `connector_error_json.message` before
+ * it reaches a durable spine event and the owner's UI. That gap is why
+ * Venmo's first live run (`run_1787101857760`, 2026-08-18) hit the SAME
+ * defect the mechanism was built to fix: `venmo_session_failed: [REDACTED]:
+ * Failed to fetch`, the eaten token being `venmo_probe_transport_error` (27
+ * chars) — a categorical, PII-free fault-class name, not a secret.
+ *
+ * WHY THIS IS A MANIFEST READ AND NOT A REGISTRY
+ * ----------------------------------------------
+ * Which fault-class names a connector throws is a CONNECTOR FACT, so the
+ * connector declares it, in the one place connectors already declare their
+ * facts to the RI: `capabilities.declared_reason_tokens` in the manifest.
+ *
+ * This module previously held a hardcoded `Map` keyed by connector id whose
+ * one entry imported `VENMO_DECLARED_REASON_TOKENS` straight out of
+ * `packages/polyfill-connectors/src/auto-login/venmo.ts`. That is a literal
+ * connector identity plus a direct cross-package import of connector code
+ * into RI production source — both of which the zero-connector-knowledge
+ * conformance guard forbids, and rightly: the RI would need a code change to
+ * support the next connector that needs this.
+ *
+ * The token list is now read generically off whatever manifest the run
+ * resolved. The RI never learns a connector name. A connector that declares
+ * nothing gets `undefined` and therefore exactly today's
+ * `boundConnectorErrorMessage` behavior, byte-identical — an absent
+ * declaration is treated as an empty set, same as before.
+ *
+ * SAFETY: the >=24-char/snake_case shape is enforced at manifest REGISTRATION
+ * time by `server/connector-manifest-validation.ts`'s
+ * `validateDeclaredReasonTokensCapability`, not here. A declared token is an
+ * instruction to skip redaction, so an unvalidated one would let a connector
+ * declare a string matching its own live credential and have the runtime
+ * print that credential into a durable event. Rejecting the manifest is the
+ * correct place to stop that: it fails before the connector can ever run.
+ * This function deliberately does not re-validate — a token that reached a
+ * registered manifest already passed that gate, and a second, weaker copy of
+ * the rule here would be the thing that drifts.
+ */
+
+/**
+ * The manifest shape this lookup needs: nothing but the declared tokens.

+// `flushBatch` issued a bare `fetch` and threw on any non-2xx, killing the whole
+// run and discarding every record still buffered for it.
+//
+// ─── Relationship to the device-exporter path ───────────────────────────────
+//
+// The local device/collector path already survives exactly this 503 storm, and
+// it is the reference this module mirrors — deliberately, at the level of
+// POLICY rather than code:
+//
+//   - `classifyLocalDeviceFailure` (packages/polyfill-connectors/src/collector-runner.ts)
+//     classifies retryability from STRUCTURED fields only — a typed HTTP status,
+//     a typed timeout class — never from error message prose. {@link isRetryableIngestStatus}
+//     keeps that rule: it reads a numeric status and nothing else.
+//   - `failOutboxItem` (same file) honors the server's `Retry-After` bounded by
+//     `maxRetryAfterMs`, and otherwise falls back to its own backoff schedule.
+//     {@link nextIngestRetryDelayMs} keeps that precedence and that bound.
+//
+// The two paths deliberately do NOT share an implementation, because they do
+// not share a mechanism. The device path is DURABLE: a failed batch stays a
+// `ready` row in a SQLite outbox and is re-attempted on a later runner
+// invocation, so its "retry" spans process lifetimes and its bound is an
+// attempt counter persisted in a table. The connector runtime holds its batch
+// only in memory inside `flushBatch`, so its retry must complete within the
+// call or the records are gone. Extracting a common helper would have to
+// abstract over "durable row" vs "in-memory array", producing a shallow
+// wrapper that hides no real depth — and would put the one path that
+// demonstrably works at risk to serve the one that does not. The shared thing
+// worth sharing is the policy, which is documented here and asserted by tests
+// in both places.
+//
+// ─── Why an in-request retry is safe here (idempotency) ─────────────────────
+//
+// Re-POSTing an identical batch cannot double-write, and this was verified
+// against the storage layer rather than assumed.
+//
+// The `records` table carries `UNIQUE(connector_instance_id, stream, record_key)`
+// on both backends (server/db.ts for SQLite, server/postgres-storage.ts for
+// Postgres), and every write is an upsert — `ON CONFLICT (connector_instance_id,
+// stream, record_key) DO UPDATE` (server/postgres-records.ts, and the SQLite
+// equivalent in server/records.ts). `record_key` is the connector-supplied
+// envelope `key`, canonically encoded by `encodeKey`. A record that landed on
+// attempt 1 is therefore OVERWRITTEN on attempt 2, not appended; when the
+// payload is byte-identical the write short-circuits to a no-op that does not
+// even bump the row's version.
+//
+// This matters more than it might appear, because a batch is NOT written
+// atomically. `ingestRecordsWithinCoordinator` (server/records.ts) commits each
+// record in its OWN transaction, so when a few records in a batch of 100 fail
+// on `connector_instance_busy`, the other 96 have already committed durably —
+// the 503 changes only what the HTTP response reports, never what is in the
+// table. Replaying the whole batch re-upserts those 96 onto their existing rows
+// instead of duplicating them, which is exactly why an accepted-prefix does not
+// corrupt data on retry. The operation documents this contract at
+// operations/rs-records-ingest/index.ts, `ref-error-status.ts` states a 503 is
+// "safe to retry the identical batch", and
+// test/runtime-ingest-systemic-failure-contract.test.ts proves the end-to-end
+// no-duplicate-rows property against a real server.
+//
+// The one caveat, which belongs to the connector rather than to this module:
+// dedup is keyed on the record key the CONNECTOR emits. A connector that emits
+// a nondeterministic key (a fresh uuid, a collection timestamp) for the same
+// logical record would write two rows on a replay, and no server-side
+// constraint can detect that. Retrying does not introduce that hazard — a
+// connector with unstable keys already duplicates across ordinary re-runs — but
+// it does mean retry-safety here rests on key stability, which is a per-
+// connector property this module cannot enforce.
+//
+// ─── What this module deliberately does NOT retry ───────────────────────────
+//
+// Only a status the server marked retryable. A 4xx stays fatal on the first
+// response exactly as before: a 400/422 means the RS rejected this batch on its
+// CONTENT, and replaying identical content would only reproduce the rejection
+// while delaying an honest terminal failure. 401/403 are credential faults that
+// no amount of waiting repairs. A 2xx envelope reporting `records_rejected` is
+// the per-record isolation contract and never reaches this module.
+
+/**
+ * Bounds for one batch's retry sequence. Every field is finite by
+ * construction: the sequence can never exceed `maxAttempts` requests, and

+ * 500". Burning the retry budget on a 500 only delays an honest terminal
+ * failure and, worse, hides it: the run reports `ingest_endpoint_saturated`

+ * "the server does not mean retry" but "this is not the layer that should".
+ * A 503 here is writer-admission contention
+ * (`connector_instance_busy`) — local, sub-second, and genuinely cleared by
+ * waiting a few hundred milliseconds, which is exactly what this runtime's
+ * 4-attempt / ~3.5s budget buys. A 429 is SOURCE PRESSURE from the upstream
+ * provider, measured in minutes to hours, and retry ownership for it belongs
+ * to the SCHEDULER, not this runtime:
+ *
+ *   - `server/stores/terminal-gap-classifier.ts:20` states the rule directly:
+ *     429 is explicitly transient, must NEVER terminalize a gap, and arms the
+ *     source-pressure cooldown instead.
+ *   - `scheduler-source-pressure-cooldown.ts` owns that cooldown, backs off up
+ *     to `DEFAULT_MAX_COOLDOWN_MS` (6 hours), and persists it ACROSS runs.
+ *
+ * Absorbing a 429 here actively destroys runs. This loop burns its whole ~3.5s
+ * budget against a limit that will not lift in 3.5s, then fails terminally as
+ * `INGEST_SATURATED_FAILURE_REASON` — so the scheduler never observes the

+ * Derives a connector's refresh mode from the facts that actually determine
+ * it, instead of trusting a hand-written `recommended_mode` string.
+ *
+ * WHY THIS EXISTS
+ *
+ * `capabilities.refresh_policy` carried three independently hand-written
+ * fields — `recommended_mode`, `background_safe`, `assisted_after_owner_auth`
+ * — that were supposed to agree and did not. Measured across the shipped
+ * manifests, `background_safe` had stopped discriminating anything: Notion (a
+ * pure API-token connector with nothing to interact with) and Chase (an
+ * interactive-OTP bank) both declared `background_safe: false`, for entirely
+ * different reasons, neither of which was "unattended refresh is impossible".
+ * The Notion/Oura/Strava/Steam/Jellyfin rationales say so outright — they read
+ * "unproven pending credentialed live testing", which is a MATURITY statement
+ * wearing a SAFETY flag's clothes.
+ *
+ * Those are two different facts and the manifests already declare both:
+ *
+ *   - CAPABILITY  — `refresh_policy.interaction_posture`: what human gesture,
+ *     if any, each run needs. This field stayed honest because it is an
+ *     enum with a validated domain rather than a free boolean.
+ *   - MATURITY    — `public_listing.tier`: whether this connector has been
+ *     proven on a real deployment yet.
+ *
+ * Mode is a function of CAPABILITY only. Maturity is enforced separately by
+ * the `public_listing.tier` gate that auto-enrollment already applies, so an
+ * unproven connector does not get auto-scheduled merely because it derives
+ * as automatic. Keeping them apart is the whole point: previously a connector
+ * could only express "not proven yet" by lying about what it is capable of,
+ * and that lie then leaked into every consumer of `background_safe`.
+ *
+ * ARCHITECTURE PRECEDENT (load-bearing)
+ *
+ * This repo has a standing ruling that a derivation FORMULA must not live in
+ * a manifest: a manifest may DECLARE a fact or SELECT a closed variant, but
+ * the reference implementation owns formulas. So this module reads declared
+ * inputs (`interaction_posture`, `background_safe`) and owns the rule. No
+ * manifest gains a field describing HOW its mode is computed.
+ *
+ * THE RULE
+ *
+ * Default to automatic, and only step down to manual when a declared fact
+ * says a human gesture is required per run:
+ *
+ *   manual_action_likely -> manual, UNLESS the connector declares
+ *                           `background_safe: true`, which is how a browser
+ *                           connector states that the owner's session
+ *                           persists across runs after the first login
+ *                           (ChatGPT, WHOOP, Google Calendar/Contacts).
+ *   otp_likely           -> manual, UNLESS `background_safe: true` for the
+ *                           same session-persistence reason (Amazon, Reddit,
+ *                           H-E-B). Chase/USAA/Venmo/Whole Foods do not
+ *                           declare it and stay manual.
+ *   none | credentials   -> automatic. There is no per-run gesture to make.
+ *   (undeclared posture) -> automatic, per the owner's explicit default:
+ *                           prefer automatic until a connector proves it must
+ *                           not be.
+ *
+ * `assisted_after_owner_auth` is deliberately NOT an input here. It answers a
+ * different question — may a run that has already started ask the owner for
+ * bounded help — and `runtime/run-automation-policy.ts` already consumes it
+ * that way, mapping it to `automation_mode: "assisted"` while still allowing

+ * Which staged checkpoints survive a CONTROLLER restart.

+ * `commitState` runs only from `handleDoneClose`. A run whose controller is
+ * replaced mid-walk never reaches DONE, so it commits no cursor however long
+ * it ran. A walk longer than the interval between deploys therefore never
+ * converges — that is a COMPLETENESS failure, not a slowness one. Measured on
+ * this instance: 45 runs ended this way between 2026-08-15 and 2026-08-22,
+ * concentrated in the longest walks (9 Slack, 4 Gmail, 3 YNAB, plus Amazon and
+ * Google Maps).
+ *
+ * ## Why it is safe, and narrow
+ *
+ * The rule it carves out of exists to protect ONE invariant: a cursor must
+ * never advance past records whose detail coverage was not proven. This
+ * exception preserves that invariant structurally rather than trusting it:
+ *
+ *  - A stream that is a declared detail-coverage PARENT can face a DONE-time
+ *    shortfall verdict, so it is excluded outright. Eligibility is read from
+ *    the MANIFEST — a connector cannot declare itself eligible. (Ruling D10:
+ *    qualification is proven, never self-declared. Voluntary honesty is a
+ *    failure mode this program has already been burned by.)
+ *  - A stream carrying a pending detail gap, or unproven coverage for the
+ *    completed prefix, is excluded — the uncertain case fails CLOSED.
+ *  - Only a CONTROLLER-lifecycle death qualifies. A connector that reported
+ *    its own failure is not covered: its state map is unproven by definition.
+ *
+ * The run stays failed/abandoned and every withheld stream stays eligible for
+ * retry. Nothing here makes a run look more complete than it was.

+ * A run-scoped logger seam for connector-runtime code paths — scheduler,
+ * run-executor, maintenance sweeps — that know a run's identity but have no
+ * way to reach the structured logger the server already builds.
+ *
+ * Why this exists (design-notes/failure-diagnosability-2026-08-18.md): the
+ * server builds a real Pino instance (`transport.ts` `buildLogger`) and
+ * passes it deep into `server/index.ts`'s boot/runtime closures — it is NOT
+ * confined to route handlers, contrary to the note's open question. But
+ * `runtime/scheduler.ts` and `runtime/scheduler/run-executor.ts`, which own
+ * every `run_id` in the system, never receive it. Their failures go to
+ * `console.error` with a `[scheduler]` tag and nothing else — no `run_id`,
+ * no `connector_instance_id`. That is the mechanical reason a failed run's
+ * own log lines cannot be found by grepping its run_id: the code that would
+ * write them cannot reach a logger, let alone one that knows the run.
+ *
+ * This is NOT a new logging framework and does NOT require every module to
+ * adopt it. It is one small factory: given a base logger (Pino, or anything
+ * shaped like it) and a run's identity, return a logger whose every line
+ * carries `run_id`, `connector_id`, and `connector_instance_id` — the same
+ * `logger.warn({ ...fields }, message)` call convention already used at
+ * `server/index.ts`'s `onNoProgressAlert`, so the JSON shape on disk is
+ * unchanged and nothing downstream needs a new parser.
+ *
+ * Threading: `SchedulerOptions.logger` (runtime/scheduler-domain-types.ts)
+ * is optional and flows through `createScheduler` -> `createRunExecutor` ->
+ * `RunExecutorDeps.logger`. Every existing caller that does not pass one
+ * gets `NOOP_RUN_BASE_LOGGER`, a silent no-op — this seam is additive and no
+ * existing test/call site needs to change.
+ *
+ * PII: this module does not invent a new redaction policy. Any string field
+ * a caller passes under `message` is run through `redactStderrTail` before
+ * it reaches the base logger, using the SAME declared-reason-token allowlist
+ * convention `runtime/stderr-redact.ts` documents. This matters because a
+ * run-scoped logger, once it exists, is exactly the kind of seam a future
+ * caller will be tempted to hand raw connector output — the module fails

+//     settles (it rejects), so the run that owned the request fails through
+//     its normal error path with a real reason.
+//   - It is a liveness bug in a dependency, not a signal that this process

+# deploy-canary — pre-registered deploy verification
+
+Turns a production deploy's verification from an hour of hand-typed greps,
+`psql` queries and `docker inspect` calls into one command that fails closed
+and leaves a receipt.
+
+Required by **D15** ("pre-register each step's canary metrics BEFORE deploying
+it; post-hoc success criteria are how 'green' claims died in this program")
+and **D14** ("behavior preservation is a gate, not a hope — proven by
+before/after comparison on the drain canary, not narrated").
+
+## Usage
+
+```sh
+# Dry run (DEFAULT). Reads production, changes nothing.
+node reference-implementation/scripts/canary/deploy-canary.ts \
+  --manifest=reference-implementation/scripts/canary/manifests/step-1-run-lifecycle.json \
+  --ref=fix/sweep-fairness-and-transformer-bounds
+
+# Deploy for real.
+node reference-implementation/scripts/canary/deploy-canary.ts \
+  --manifest=.../step-1-run-lifecycle.json --ref=<ref> --apply
+```
+
+`--receipt-dir=<path>` sets where receipts land (default
+`local/canary-receipts`). `connector_run` checks require BOTH
+`PDPP_OWNER_PASSWORD` and `PDPP_CANARY_ORIGIN` — the origin has no default,
+so a misconfigured invocation refuses rather than targeting some other
+instance. A check whose environment is incomplete fails; it never guesses.
+
+Exit code is `0` on pass or dry run, `1` on any blocking failure, artifact
+mismatch, or manifest rejection.
+
+## What it does, and which real failure each phase prevents
+
+| Phase | Action | The failure it exists to catch |
+|---|---|---|
+| 1 | Build from a ref, base image digest-pinned | A floating base image (a real suspected defect) |
+| 2 | **Artifact-verify**: content greps INSIDE the image | A "deploy" that never happened — production restarted onto the SAME tag while the fix was believed live for hours |
+| 3 | Capture pre-image: inspect, env, rollback target, BEFORE metrics | Nothing to compare against, and no known-good rollback target |
+| 4 | Deploy, preserving config; **rename** the old container | Lost restart policy / limits / volumes; unrecoverable rollback |
+| 5 | Run the pre-registered checks | — |
+| 6 | Emit a receipt | Claims without evidence |
+| 7 | Roll back automatically on any blocking failure | A bad deploy left running because verification was manual |
+
+Phase 2 **fails closed**: if the built image does not contain what the
+manifest asserts, nothing is deployed and the receipt records
+`ABORTED_ARTIFACT_MISMATCH`. A tag is a label anyone can move and a commit sha
+describes source, not bytes — only a grep inside the image is evidence.
+
+## Manifest schema
+
+```jsonc
+{
+  "step": "step-1-run-lifecycle",
+  "description": "...",
+  "container": "pdpp-core-prod-drain",   // the production container
+  "imageRepo": "pdpp-core",
+  "imageTag": "canary-step1",
+  "dockerfileTarget": "core",
+  // MUST contain @sha256: — a floating base is rejected at parse time.
+  "nodeBaseImage": "node:24.19.0-bookworm-slim@sha256:3638d9a6...",
+  "postgresContainer": "pdpp-postgres-1",
+
+  // At least one is REQUIRED. Checked inside the image BEFORE deploying.
+  "artifactAssertions": [
+    { "id": "...", "description": "...", "path": "/app/...", "pattern": "...", "minCount": 1 }
+  ],
+
+  "checks": [ /* see below */ ]
+}
+```
+
+Every check has `id` (unique), `description`, `kind`, and `blocking`. Only a
+failing **blocking** check triggers rollback.
+
+### Check kinds
+
+- **`sql_scalar`** — `sql`, `predicate`, optional `bound`. Predicates:
+  `must_not_increase`, `must_not_decrease`, `must_equal`, `must_stay_zero`,
+  `must_be_at_most`, `must_be_at_least`. Threshold/equality predicates require
+  `bound`. A `must_not_*` predicate with no BEFORE value fails closed.
+- **`sql_timestamp`** — `sql`, `predicate: "must_not_advance"`. Appearance and
+  disappearance both count as failures.
+- **`container_fact`** — `fact: "restart_count" | "running_image"`. Use
+  `must_change` on `running_image` to prove the container actually picked up
+  the new bytes.
+- **`log_pattern`** — `pattern`, `maxOccurrences`, `sinceSeconds`. `0` means
+  "must not appear"; a positive value allows an expected containment message.
+- **`http_health`** — `url`, `expectStatus`.
+- **`connector_run`** — `connectionId`, `connectorSlug`, `timeoutSeconds`.
+  Triggers a real run and waits for `succeeded`. A timeout reports `timeout`,
+  not `failed`: an unfinished run is an unknown.
+
+## The OTP denylist — a code-level gate
+
+`usaa`, `chase`, `heb`, `amazon`, `venmo`, `reddit`.
+
+Each of these sends a **real one-time password to the owner's phone** when a
+run starts. One was burned when a crash killed a run 49 seconds after the code
+arrived.
+
+Enforcement is in code, not a comment:
+
+1. **At manifest-parse time** — `parseManifest` throws `ManifestError` on a
+   `connector_run` naming a denylisted connector. The manifest never loads, so
+   the deploy path is never entered and no receipt is written.
+2. **Again at the trigger site** — `triggerConnectorRun` re-checks before
+   issuing any HTTP request. This is the last point before an irreversible
+   side effect, and a check there should not rely on a caller having validated.
+
+The denylist is a hard-coded constant, not manifest configuration: a denylist
+a manifest can edit is one an operator can disable at 2am, which is exactly
+when it matters. Matching normalizes case and separators, so `USAA`,
+`chase-bank` and `chase_bank` are all caught, while `chaseable` is not.
+
+`connectorSlug` is a required field precisely so the gate cannot be dodged by
+supplying only an opaque `cin_...` the parser cannot classify.
+
+## Env derivation — the rule, and both failure modes
+
+`docker inspect .Config.Env` returns the container's FULL environment: the
+operator's `-e` flags **and** everything baked into the image. Replaying all 97
+vars onto a new image re-injects the OLD image's values. So some filtering is
+needed — and this is where it went wrong twice in one day, in both directions.
+
+**The tempting rule, which is catastrophic.** "Drop anything the image also
+declares" — filtering by NAME. Measured against the live container that drops
+25 vars, and 5 of them are real operator overrides that merely share a name
+with an image default:
+
+```
+PDPP_DB_PATH                   image=/var/lib/pdpp/pdpp.sqlite
+                               live =/root/.pdpp/pdpp.sqlite      <-- the database
+PDPP_CONNECTOR_ARTIFACT_ROOT, PDPP_EMBEDDING_CACHE_DIR,
+PDPP_REFERENCE_ORIGIN, PDPP_REFERENCE_REVISION
+```
+
+Dropping `PDPP_DB_PATH` points production at the **wrong database**. Nothing
+about the name distinguishes a real override from an image default.
+
+**The over-correction.** Filtering by a hand-written list dropped `NODE_ENV`
+and `PLAYWRIGHT_BROWSERS_PATH` and broke connector execution.
+
+**The rule used here.** Drop a variable only when the new image declares the
+**same name AND the same value**. Then dropping it is provably a no-op: the
+image supplies an identical value, or a deliberately updated one that *should*
+win (this is how a new base image's `PATH` takes effect). Any differing value
+is, by construction, information the image does not have — an override — and is
+carried.
+
+Measured live: **77 carried, 20 dropped, 5 overrides preserved and reported.**
+
+Because "provably a no-op" is a claim about values the operator cannot see at
+a glance, the tool **reports every dropped var and prints each carried
+override with both values** so a wrong call is caught before it lands.
+
+Secrets are redacted by name in both console output and receipts.
+
+## The TEXT-timestamp trap
+
+`records.emitted_at`, `device_ingest_batch_outcomes.created_at`,
+`run_history.started_at` and friends are **`text`**, not `timestamptz`.
+Postgres compares TEXT to a cast interval lexicographically and silently
+matches the wrong rows. Measured live, for the same intended window:
+
+```sql
+-- WRONG: returned 208
+where created_at > (now() - interval '1 hour')::text
+-- RIGHT: returned 8
+where (created_at)::timestamptz > now() - interval '1 hour'
+```
+
+A 26x overcount that still looks like a number. `parseManifest` **rejects** a
+query that compares such a column to an interval without an explicit
+`::timestamptz`. Set `"requireExplicitCast": false` on a check to accept the
+risk deliberately.
+
+Related trap, in the seeded manifest: the naive "non-terminal runs" metric
+(`run.started` minus terminal events) measured **2**, not 0 — both were runs
+legitimately in flight, seconds old. A `must_stay_zero` on that form would
+fire a **false rollback** on any deploy landing while a connector is running.
+The shipped check bounds it by age (`status='running'` older than 2 hours), so
+it means *stuck*, not *busy*.
+
+## Receipt format
+
+JSON at `<receipt-dir>/canary-<step>-<timestamp>.json`:
+
+```jsonc
+{
+  "tool": "deploy-canary",
+  "step": "...", "ref": "...", "refCommit": "<full sha>",
+  "image": "pdpp-core:canary-step1", "imageDigest": "sha256:...",
+  "nodeBaseImage": "node:24.19.0-bookworm-slim@sha256:...",
+  "container": "pdpp-core-prod-drain",
+  "rollbackTarget": { "image": "pdpp-core:drain32", "containerName": "...-prev-<ts>" },
+  "env": {
+    "carriedCount": 77,
+    "droppedAsImageIdentical": ["NODE_ENV", "PATH", "..."],
+    "carriedOverrides": [{ "name": "PDPP_DB_PATH", "liveValue": "...", "imageValue": "..." }]
+  },
+  "artifactAssertions": [{ "id": "...", "pattern": "...", "expectedMin": 1, "actual": 1, "passed": true }],
+  "checks": [{ "id": "...", "kind": "...", "blocking": true, "before": 8, "after": 8, "passed": true, "detail": "8 <= 8" }],
+  "rolledBack": false,
+  "verdict": "PASS",           // PASS | FAIL | DRY_RUN | ABORTED_ARTIFACT_MISMATCH
+  "startedAt": "...", "finishedAt": "...", "dryRun": false
+}
+```
+
+Every check records **both** `before` and `after`, which is what makes D14's
+before/after comparison a gate rather than a narration.
+
+## Rollback
+
+On any blocking failure the tool stops the new container, renames it aside
+(`...-prev-<ts>-failed`, so its logs survive for diagnosis), renames the
+original back, and starts it. The receipt sets `"rolledBack": true`,
+`"verdict": "FAIL"`, and lists each blocking failure.
+
+The outgoing container is **renamed, never removed**, so rollback does not
+depend on this tool having reconstructed the `docker run` spec correctly — if
+reconstruction were the only copy of the config, a bug here would make
+rollback impossible exactly when it is needed.
+
+**The tool never removes a Docker volume.** There is no `docker volume` call
+and no `down -v` anywhere in it. A prior incident destroyed 562 volumes.
+
+It also deliberately does not use `scripts/reference-stack.sh`: that would
+start a **parallel** stack rather than replacing production, which during an
+incident looks like a successful deploy while the old container keeps serving.
+
+## Tests
+
+```sh
+cd reference-implementation
+node --test --import tsx test/canary-harness-manifest.test.ts
+```
+
+Covers predicate evaluation, denylist enforcement (including casing and
+separator spellings), receipt-relevant redaction, rollback triggering, env
+derivation against the real 97-var/25-var fixtures, and container-spec
+preservation. Fixtures are taken from the live instance, so the assertions are
+about real failure modes.
+
+Mutation-checked: reverting `deriveEnv` to name-based filtering (the
+catastrophic rule) fails 4 tests; disabling the OTP denylist fails 1.

+ *
+ * Why a triggered run is worth the trouble
+ * ---------------------------------------
+ * SQL counters and restart counts prove the process did not crash. They do
+ * NOT prove the thing the owner actually cares about — that a connector can
+ * still complete a run end to end. A Slack run was structurally impossible
+ * before today's undici fix while every counter looked healthy, so a
+ * liveness check that exercises the real path is the difference between
+ * "nothing got worse" and "it works".
+ *
+ * The cost, and the gate
+ * ----------------------
+ * Six connectors dispatch a real one-time password to the owner's phone when
+ * a run starts. Those codes are finite, rate-limited, and land on a human's
+ * lock screen; one was burned today when a crash killed a run 49 seconds
+ * after the code arrived. `manifest.ts` rejects those connectors at PARSE
+ * time, and `triggerConnectorRun` re-checks the slug here before issuing the
+ * request. The duplication is deliberate: this function is the last point
+ * before a real text message is sent, and a check at the boundary of an
+ * irreversible side effect should not rely on a caller having validated.

+ *
+ * Why this file exists
+ * --------------------
+ * Production is a hand-rolled `docker run`, not compose-managed. There is no
+ * declarative file to re-apply, so the ONLY authoritative description of how
+ * production is configured is the running container itself. Anything this
+ * module forgets to copy is silently lost at the next deploy: a dropped
+ * `--restart` leaves production unable to survive a reboot, a dropped volume
+ * detaches the database, a dropped memory limit lets one run take down the
+ * host.
+ *
+ * `scripts/reference-stack.sh` is deliberately NOT used. It would start a
+ * PARALLEL stack alongside production rather than replacing it, which during
+ * an incident looks like a successful deploy while the old container keeps
+ * serving traffic.
+ *
+ * Rollback posture
+ * ----------------
+ * The old container is RENAMED, never removed. A rename keeps the whole
+ * object — its config, its logs, its writable layer — recoverable by a single
+ * `docker rename` back, so rollback does not depend on this module having
+ * reconstructed the spec correctly. That matters: if the reconstruction were
+ * the only copy of the config, a bug here would make rollback impossible at
+ * exactly the moment it is needed.

+ * deploy-canary
+ *
+ * Owner/operator-only tool that deploys one ref to the production container
+ * and verifies it against PRE-REGISTERED metrics, emitting a durable receipt.
+ *
+ * Why this tool exists
+ * --------------------
+ * Six deploys happened by hand in one day, each verified by manually typing
+ * greps, psql queries and `docker inspect` at a terminal. Three failure modes
+ * recurred, and none of them is a mistake a careful operator stops making —
+ * they are all invisible unless something checks mechanically:
+ *
+ *   1. A deploy that never happened. Production restarted onto the SAME image
+ *      tag; the fix was believed live for hours while Gmail kept destroying
+ *      data. A tag is a label and a commit sha describes source, not bytes.
+ *      Only a grep INSIDE the image caught it. Phase 2 makes that grep a
+ *      required gate that fails closed before anything is deployed.
+ *
+ *   2. Env filtering broke the container twice, in both directions. See
+ *      `env-derivation.ts`; the short version is that dropping vars by NAME
+ *      would have pointed production at the wrong database.
+ *
+ *   3. Success criteria chosen after seeing the results. D15: "post-hoc
+ *      success criteria are how 'green' claims died in this program." The
+ *      manifest is parsed and frozen before the build, and the evaluator is
+ *      pure, so the rule cannot be edited to fit the number.
+ *
+ * Phases
+ * ------
+ *   1 build            image from a ref, base image digest-pinned
+ *   2 artifact-verify  content greps inside the image; FAIL CLOSED
+ *   3 capture          full inspect, env, rollback target, BEFORE metrics
+ *   4 deploy           rename old container (never remove), run new one
+ *   5 check            the pre-registered predicates
+ *   6 receipt          durable JSON artifact
+ *   7 rollback         automatic on any blocking failure, loudly recorded
+ *
+ * Safety
+ * ------
+ *   - DRY RUN BY DEFAULT. `--apply` is required to build or change anything.
+ *     A dry run performs every read-only step (inspect, env derivation,
+ *     BEFORE metrics) and prints the exact `docker run` argv it would use.
+ *   - The outgoing container is RENAMED, not removed, so rollback never
+ *     depends on this tool having reconstructed the spec correctly.
+ *   - No volume is ever removed. A prior incident destroyed 562 volumes;
+ *     this tool contains no `docker volume` call and no `down -v`.
+ *   - Connector runs for OTP-gated connectors are refused at manifest-parse
+ *     time and again at the trigger site.
+ *
+ * Usage:
+ *   node reference-implementation/scripts/canary/deploy-canary.ts \
+ *     --manifest=reference-implementation/scripts/canary/manifests/step-1-run-lifecycle.json \
+ *     --ref=fix/sweep-fairness-and-transformer-bounds \

+ * canary/env-derivation
+ *
+ * Decides which environment variables to carry from the running container
+ * onto its replacement.
+ *
+ * Why this file exists
+ * --------------------
+ * This one decision broke production twice in a single day, in both possible
+ * directions, and each failure mode looks correct while you are making it.
+ *
+ * `docker inspect .Config.Env` returns the container's FULL environment: the
+ * operator's `-e` flags AND everything baked into the image. Replaying all 97
+ * vars onto a new image re-injects the OLD image's values — a stale `PATH` or
+ * `NODE_VERSION` from the previous build, silently overriding the new image's
+ * own. So some filtering is required.
+ *
+ * The tempting filter is by NAME: "drop anything the image also declares".
+ * Measured against the live container, that rule drops 25 vars — and 5 of
+ * them are real operator overrides that merely share a name with an image
+ * default:
+ *
+ *     PDPP_DB_PATH              image=/var/lib/pdpp/pdpp.sqlite
+ *                               live =/root/.pdpp/pdpp.sqlite      <-- the database
+ *     PDPP_CONNECTOR_ARTIFACT_ROOT, PDPP_EMBEDDING_CACHE_DIR,
+ *     PDPP_REFERENCE_ORIGIN, PDPP_REFERENCE_REVISION
+ *
+ * Dropping `PDPP_DB_PATH` points production at the WRONG DATABASE. The
+ * name-based rule is confidently, catastrophically wrong, and nothing about
+ * the name distinguishes a real override from an image default.
+ *
+ * The opposite over-correction also happened: filtering too aggressively by a
+ * hand-written list dropped `NODE_ENV` and `PLAYWRIGHT_BROWSERS_PATH` and
+ * broke connector execution.
+ *
+ * The rule that is actually right
+ * ------------------------------
+ * Drop a variable only when the image declares the SAME NAME AND THE SAME
+ * VALUE. Then dropping it is provably a no-op: the new image supplies an
+ * identical value, or a deliberately updated one that SHOULD win (this is how
+ * a `PATH` or `NODE_VERSION` change in a new base image takes effect). Any
+ * value that differs is, by construction, information the image does not
+ * have — an operator override — and is carried forward.
+ *
+ * Measured live: 20 of 25 name-collisions are value-identical (safe), 5 are
+ * real overrides (carried). Both failure modes are excluded by the same rule.
+ *
+ * Because "provably a no-op" is a claim about VALUES, and values are what the
+ * caller cannot see at a glance, `deriveEnv` reports every variable it drops
+ * so the operator can catch a wrong call before it reaches production.

+ *
+ * The pre-registered metric manifest: its schema, its validation, and the
+ * pure predicate evaluator that decides pass/fail.
+ *
+ * Why this file exists
+ * --------------------
+ * D15 says pre-register each step's canary metrics BEFORE deploying it,
+ * because "post-hoc success criteria are how 'green' claims died in this
+ * program". A criterion invented after seeing the number is not a check; it
+ * is a rationalization with a number attached.
+ *
+ * The mechanism that makes pre-registration real is *separation in time*:
+ * the manifest is parsed, validated, and frozen BEFORE the deploy, and the
+ * evaluator here can only compare a `before` value to an `after` value using
+ * a predicate that was already written down. Nothing in this module can read
+ * the result and then choose the rule. It has no I/O at all — that is the
+ * point, and it is why the harness's judgment lives here rather than beside
+ * the shell commands that collect the numbers.
+ *
+ * The safety property this module owns
+ * ------------------------------------
+ * A canary that triggers a connector run costs the owner a real one-time
+ * password on his phone. OTP-gated connectors are refused at PARSE time, so a
+ * denied run check cannot reach the deploy path even if a manifest asks for
+ * it. It is a code-level gate, not a comment asking nicely.
+ *
+ * The refusal set is DERIVED fail-closed from connector manifests (see
+ * `otp-posture.ts`) rather than hand-listed here. The hand-listed version had
+ * already drifted — it missed `wholefoods`, which declares an OTP posture in
+ * its own manifest — and a denylist that misses one connector is false
+ * confidence. Derivation is asymmetric: a manifest can only add itself to the
+ * refusal set, never remove itself, so this is strictly harder to disable at
+ * 2am than the constant it replaces.

+ *
+ * Computed once at module load: the value is a function of manifest facts on

+ * canary/otp-posture
+ *
+ * Decides which connectors the canary harness refuses to auto-trigger,
+ * because triggering them texts a real one-time password to the owner's
+ * phone. The answer is DERIVED from connector manifests, never hand-listed
+ * here, and it is derived FAIL-CLOSED.
+ *
+ * Why derivation rather than a hardcoded list
+ * -------------------------------------------
+ * The list used to be six string literals in `manifest.ts`. That is
+ * connector-specific executable knowledge inside RI production code, which
+ * the zero-connector-knowledge contract exists to forbid — and the contract
+ * is right, because a hand-maintained list drifts the moment a connector is
+ * added. It had already drifted: `wholefoods` declares
+ * `interaction_posture: "otp_likely"` and `human_interaction: ["otp"]` in its
+ * own manifest, and was NOT in the hardcoded six. A denylist that misses one
+ * connector is worse than no denylist, because it is false confidence with a
+ * name attached.
+ *
+ * Why this is not "a denylist a manifest can disable at 2am"
+ * ----------------------------------------------------------
+ * That objection is the right instinct, and it is what D10 encodes:
+ * qualification is proven, never self-declared. So the derivation is
+ * deliberately asymmetric, and the asymmetry is the whole design:
+ *
+ *   - Declaring an OTP posture can only ADD a connector to the refusal set.
+ *   - NOTHING a manifest declares can REMOVE a connector from it.
+ *
+ * A connector is allowed to be canary-triggered only when it positively
+ * proves a non-interactive posture: its `interaction_posture` must be one of
+ * a CLOSED, RI-OWNED set of values ({@link CANARY_TRIGGERABLE_POSTURES}) that
+ * this file — not the manifest — decides are safe, AND it must not name `otp`
+ * in `human_interaction`. Anything else is refused: an unknown posture, a
+ * missing posture, a missing manifest, a malformed manifest, an unreadable
+ * manifest directory. Silence is refusal, and so is novelty.
+ *
+ * That makes the 2am failure mode inert. An operator editing a manifest to
+ * dodge the guard has to write a posture value this file already blesses; if
+ * he invents one, or deletes the field, or deletes the file, the connector
+ * becomes MORE refused, not less. The lie a manifest can tell only costs its
+ * author a canary run it wanted.
+ *
+ * In the ruling's terms this is shape (b): the manifest SELECTS a closed
+ * RI-owned variant. Omission yields a withheld verdict (refusal), never a
+ * green one — which is exactly the condition under which shape (b) is sound.
+ * Shape (a) would be wrong (the connector could opt itself IN to being
+ * triggered) and shape (c) is what we are replacing, because an RI-owned
+ * registry of connector names is the drift that produced the wholefoods gap.

+ * Operator tool: apply (or dry-run) a set of explicit connector-instance
+ * groupings against Postgres. This is the ONLY way `connector_instance_groups`
+ * rows should be written in production -- there is no runtime code path that
+ * infers or writes a grouping automatically.
+ *
+ * A "grouping" declares that a fragment `connector_instances` row is the SAME
+ * logical provider account as a canonical row. It is a pure alias/read-model
+ * fact: this tool NEVER rewrites `connector_instances`, moves `records`, or
+ * deletes anything. See server/connector-instance-canonicalization.ts for the
+ * read-side resolver this table feeds, and the mapping input format below.
+ *
+ * Usage (from reference-implementation/):
+ *   node --import tsx scripts/connector-instance-groups-migrate.ts <mappings.json>
+ *       [--apply] [--actor <name>]
+ *
+ * Without --apply, this is a dry run: it validates every mapping, prints what
+ * WOULD change, and writes nothing. Requires PDPP_DATABASE_URL or
+ * DATABASE_URL to point at the target Postgres database. Requires
+ * connector_instance_groups to already exist (created by the app's normal
+ * Postgres bootstrap — run the app once against the target DB first, or apply
+ * the CREATE TABLE block from server/postgres-storage.ts by hand).
+ *
+ * Mapping file shape (JSON array). Each entry is either a grouping directive
+ * or an explicit no-group record (documents a considered-but-rejected pair so
+ * the decision is never silent):
+ *
+ *   {
+ *     "connectorInstanceId": "cin_...",        // the fragment
+ *     "canonicalConnectorInstanceId": "cin_...", // the canonical row, or null for a no-group record
+ *     "reason": "proven_subset" | "verified_identity" | "owner_confirmed" | "unresolved_identity",
+ *     "evidence": { ...free-form proof, e.g. overlap counts, verified email, owner confirmation timestamp... }
+ *   }
+ *
+ * Entries with `canonicalConnectorInstanceId: null` are validated (fragment
+ * exists, owner matches) but never written to connector_instance_groups --
+ * they exist purely so a rejected pairing (e.g. GitHub's different provider
+ * user id) is recorded in the audit output as a considered-and-declined case,
+ * not silently absent from the mapping file.

+ * Orphaned-record disposition DRY RUN. Reports only — never mutates.
+ *
+ * Two distinct conditions strand the owner's records, and they need different
+ * dispositions. This script classifies every affected connector instance and
+ * prints a table the owner can approve or reject. It issues `SELECT`
+ * statements exclusively: no DELETE, no UPDATE, no INSERT, no reassociation.
+ *
+ * Condition A — ORPHANED: live records whose `connector_instance_id` has no
+ * `connector_instances` row. `records` has no foreign key to
+ * `connector_instances`, so a connection delete leaves its rows behind. No
+ * owner surface enumerates these, so they are invisible everywhere.
+ *
+ * Condition B — HIDDEN FRAGMENT: a `connector_instances` row that DOES exist
+ * but is excluded from the Sources list by
+ * `SOURCES_VISIBLE_IDENTITY_PAGE` (binding kind `historical_archive` +
+ * `recovery_reason` `connection_metadata_missing`, no UAT-transfer marker).
+ * These remain reachable through Explore's connection facets; they are hidden
+ * from one list, not stranded.
+ *
+ * For each orphaned instance the script computes whether its records are a
+ * strict subset of what a surviving connection for the same connector already
+ * holds, keyed on `(stream, record_key)`. That is the difference between
+ * "provable duplicate, safe to drop" and "unique data that must be surfaced".

+ * adjudicate-orphaned-runs
+ *
+ * Owner/operator-only tool that writes the missing terminal event for
+ * `run.started` events which no process will ever report on again, emitting
+ * `run.abandoned` with the same reason and provenance shape the boot
+ * reconciler uses.
+ *
+ * Why this tool exists
+ * --------------------
+ * `resolveControllerId` used to fall back to `os.hostname()`, which under
+ * Docker is the container ID and is fresh on every `docker run`. The boot
+ * reconciler adjudicates only orphans whose `controller_id` matches its own,
+ * so after any container replacement it matched nothing. Every run a prior
+ * container left in flight became permanently non-terminal.
+ *
+ * The identity fix stops the bleeding, but it cannot heal the backlog: those
+ * runs are stamped with container ids that no future boot will ever carry
+ * again, so the reconciler's ownership filter will keep skipping them
+ * forever. This is the one-shot pass that adjudicates them, deliberately
+ * ignoring `controller_id` because on a single-controller deployment every
+ * orphan is ours by construction.
+ *
+ * Why `run.abandoned` and not `run.failed`
+ * ----------------------------------------
+ * These runs are not known to have failed. Nobody knows what happened to
+ * them -- the process that could have said died without saying. `failed` on
+ * a bank connector means "ask the human"; `abandoned` means "nobody knows;
+ * the normal schedule will pick it up". Collapsing the two is what wakes an
+ * owner at 3am for a deploy. The distinction is the same one Kubernetes
+ * draws between a condition that is `False` and one that is `Unknown`.
+ *
+ * That distinction is not academic here: of the 134 runs the older
+ * controller path recorded as `run.failed`/`controller_restarted`, 55 had
+ * staged a cursor and 34 had durably ingested a batch before being written
+ * down as plain failures.
+ *
+ * What it does NOT do
+ * -------------------
+ *   - It never re-runs or re-queues anything. `chase`, `usaa`, `venmo`,
+ *     `heb`, `amazon` and `reddit` need an interactive human sign-in; an
+ *     automatic retry would either wake the owner or trip a provider rate
+ *     limit. Adjudication is silent by design and lets the normal schedule
+ *     pick the work up.
+ *   - It never touches `records`, and it never revises `records_emitted`.
+ *     Records validly ingested before the process died stay committed.
+ *   - It never deletes or edits an existing event. The spine is append-only;
+ *     this only adds terminal events where none exist.
+ *
+ * Safety model
+ * ------------
+ *   - Default is dry-run. `--apply` is required to write.
+ *   - The full scope is planned and printed on every invocation, including
+ *     under `--apply`, so `--apply` is never the first time the operator
+ *     sees the counts.
+ *   - Before any write, the pre-image of every targeted `run.started` event
+ *     and every `run_history` row that will be re-projected is snapshotted
+ *     into a backup table (prefix `aor_backup`), inside the same transaction
+ *     as the write.
+ *   - Idempotent by construction: each insert carries `caused_by_event_id`,
+ *     which the `spine_run_abandoned_cause_unique` partial index enforces.
+ *     A second run adjudicates nothing.
+ *   - `--limit` bounds how many orphans a single invocation will adjudicate,
+ *     so the first apply can be a small, reversible slice.
+ *
+ * Output discipline
+ * -----------------
+ * Run ids and connector ids are operational identifiers, not record
+ * payloads, but instance ids are elided anyway (`truncateId`). No record
+ * content, cursor value, or event payload is ever printed -- only counts,
+ * connector names, and dates. The pre-image lives in the backup table for
+ * the operator to inspect under their own authorization.
+ *
+ * Authorization is by direct database access -- possession of
+ * `PDPP_DATABASE_URL` (the same credential that grants owner-level access to
+ * the reference Postgres). Postgres-only, matching the sibling repair tools.
+ *
+ * Usage:
+ *   node reference-implementation/scripts/repair/adjudicate-orphaned-runs.ts \
+ *     [--connector=ynab] [--limit=25] [--apply]
+ *
+ * Env:
+ *   PDPP_DATABASE_URL   required (postgres connection string).
+ *                       PDPP_TEST_POSTGRES_URL is accepted as a fallback so
+ *                       the same CLI can run against a throwaway database.
+ *
+ * Exit codes:
+ *   0  dry-run completed, or apply completed successfully.
+ *   1  apply failed (transaction rolled back).
+ *   2  usage / configuration error (no DB url, bad --limit).

+ * gmail-backfill-target-extend
+ *
+ * Owner/operator-only repair for the Gmail "downtime-then-forward-resume" hole:
+ * a UID band that neither the forward pass nor the historical backfill will
+ * ever fetch, so the mail in it is missing permanently and silently.
+ *
+ * The defect
+ * ----------
+ * The Gmail connector keeps two independent UID cursors on the `messages`
+ * stream (see `connectors/gmail/index.ts`):
+ *
+ *   all_mail.forward_uidnext   forward watermark; the next run fetches
+ *                              `forward_uidnext:*` (selectAllMailFetchRange).
+ *   backfill.target_uid        ceiling of the historical walk; the backfill
+ *                              fetches `backfilled_through_uid+1 : target_uid`
+ *                              (selectMessagesBackfillFetchRange).
+ *
+ * `target_uid` is frozen at the value it had when the backfill cursor was
+ * first written — `advanceMessagesBackfillCursor` reads
+ * `prior.target_uid ?? priorEnd` and never re-derives it from a live
+ * `uidnext`. That freeze is correct for its purpose (it stops the historical
+ * walk from chasing a moving mailbox forever), but it has an unguarded
+ * consequence.
+ *
+ * The forward pass only advances when a run actually happens. If the
+ * connector is down while mail arrives, those UIDs land BELOW the
+ * `forward_uidnext` written by the first run after recovery, and ABOVE the
+ * `target_uid` frozen by that same run. Both cursors step over the band:
+ *
+ *     UID:  1 .......... target_uid | ORPHANED | forward_uidnext ....... *
+ *           \___ backfill walks ___/            \___ forward walks ___/
+ *
+ * Nothing ever fetches the middle. The connector still reports
+ * `covered == considered` throughout, because it did process everything it
+ * fetched — it simply never fetched this band. That is why no coverage,
+ * continuity, or health gate flagged it.
+ *
+ * What this tool does
+ * -------------------
+ * Raises `backfill.target_uid` on the `messages` cursor so the already-running
+ * historical walk continues past its frozen ceiling and through the orphaned
+ * band, instead of stopping short of it.
+ *
+ * It is deliberately the smallest possible intervention:
+ *
+ *   - It RAISES `target_uid` only. The tool refuses to lower it.
+ *   - It NEVER touches `backfilled_through_uid`, so in-flight backfill
+ *     progress is preserved exactly (rewinding it would discard the work and
+ *     re-walk the mailbox from the start).
+ *   - It NEVER touches `forward_uidnext` or `highest_modseq`, so forward
+ *     collection of new mail is unaffected.
+ *   - It never triggers a run. The owner triggers the run explicitly
+ *     afterwards, keeping the reset and the run separately auditable.
+ *
+ * Why re-collection is safe (idempotent)
+ * --------------------------------------
+ * `records` is keyed `UNIQUE(connector_instance_id, stream, record_key)` and
+ * ingest upserts via `ON CONFLICT ... DO UPDATE`. A re-collected message that
+ * is byte-identical to the stored row takes the `noop` disposition in
+ * `writePostgresIngestMutation`'s caller: no version bump and no
+ * `record_changes` row. So the walk crossing UIDs already collected costs
+ * fetch time only — it cannot duplicate records or churn change history.
+ *
+ * Why it is bounded
+ * -----------------
+ * The extension is a UID interval, not a resync. The backfill continues to
+ * consume it one bounded page per run (`PDPP_GMAIL_MESSAGES_BACKFILL_WINDOW_UIDS`,
+ * default 500). Raising the ceiling adds exactly
+ * `new_target_uid - old_target_uid` UIDs of work, no more.
+ *
+ * Safety model
+ * ------------
+ *   - Default is dry-run. `--apply` is required to write.
+ *   - Before any write, the prior `state_json` is snapshotted into a backup
+ *     table (prefix `gbte_backup`) inside the same transaction as the update.
+ *   - The update is guarded in SQL so a concurrent connector STATE commit
+ *     cannot be clobbered: it re-checks that `target_uid` still holds the
+ *     value that was read, and that the new target is strictly greater.
+ *   - Refuses to run if the stored cursor has no `backfill.target_uid`, or if
+ *     `uidvalidity` does not match the expected epoch (a UIDVALIDITY change
+ *     invalidates every stored UID and calls for a full resync instead).
+ *
+ * Output discipline
+ * -----------------
+ * Cursor UIDs are mailbox positions, not record payloads, so they are printed
+ * — they are exactly what the operator must review before applying. No message
+ * content, subject, address, or record key is ever read or printed.
+ *
+ * Authorization is by direct database access — possession of
+ * `PDPP_DATABASE_URL`, the same credential that grants owner-level access to
+ * the reference Postgres. Postgres-only, matching the sibling repair tools.
+ *
+ * Usage:
+ *   node reference-implementation/scripts/repair/gmail-backfill-target-extend.ts \
+ *     --connector-instance-id=cin_... \
+ *     --new-target-uid=324020 \
+ *     [--expect-uidvalidity=1] [--apply]
+ *
+ * Env:
+ *   PDPP_DATABASE_URL   required (postgres connection string).
+ *                       PDPP_TEST_POSTGRES_URL is accepted as a fallback.
+ *
+ * Exit codes:
+ *   0  dry-run completed, or apply completed successfully.
+ *   1  apply failed, or preconditions not met (transaction rolled back).
+ *   2  usage / configuration error.

+/**
+ * gmail-delta-blanked-envelope-restore
+ *
+ * Owner/operator-only repair for Gmail messages whose envelope was blanked by
+ * the flag/label delta pass.
+ *
+ * The defect
+ * ----------
+ * Before the fix in `connectors/gmail/index.ts`, `runDeltaPass` fetched with
+ * `envelope: false` and emitted a `messages` record whose envelope fields were
+ * all null. PDPP records are whole-document upserts — ingest sets
+ * `record_json = EXCLUDED.record_json` and there is no merge path in either
+ * backend — so that record did not update flags on the stored row, it replaced
+ * the row. Every label change or `\Seen` toggle on an already-collected
+ * message erased its `subject`, `from_name`, `from_email`, `date`,
+ * `message_id`, `size_bytes` and `snippet`, and reset `received_at` to the run
+ * clock.
+ *
+ * Why no re-fetch is needed
+ * -------------------------
+ * The blanking wrote a NEW version rather than mutating the old one, so the
+ * complete pre-blank payload is still in `record_changes`. This tool restores
+ * the current `records` projection from that retained history. Gmail is never
+ * contacted, so the account's IMAP throttle is irrelevant and no mail can be
+ * re-downloaded, altered, or deleted.
+ *
+ * What it restores
+ * ----------------
+ * For each key whose CURRENT row is blank (`subject` and `from_email` both
+ * null), the highest-versioned `record_changes` row for that key that still
+ * carries a non-null `subject`. That is the last known-good payload.
+ *
+ * Its `labels` and flag booleans are deliberately taken from the CURRENT row,
+ * not from history: those are the fields the delta pass legitimately observed,
+ * and they are the newer truth. Restoring them from history would undo real
+ * label changes. Only the fields the delta pass could not see — and therefore
+ * destroyed — come from history.
+ *
+ * Safety model
+ * ------------
+ *   - Default is dry-run. `--apply` is required to write.
+ *   - Only rows that are blank RIGHT NOW are touched; a row that has since
+ *     been re-collected in full is left alone.
+ *   - Before any write, every affected current row is snapshotted into a
+ *     backup table (prefix `gdber_backup`) inside the same transaction.
+ *   - The write is a version-guarded UPDATE: it re-checks that the current
+ *     row still holds the version that was read, so a concurrent run that
+ *     re-collected the message wins instead of being clobbered.
+ *   - Records are never deleted and no version is rewound. The restore
+ *     allocates a new version, so the blanking remains visible in history.
+ *
+ * Output discipline
+ * -----------------
+ * This is the owner's email. Only counts and truncated record keys are
+ * printed. No subject, address, snippet, or any other payload field is read
+ * into the output or into a log line.
+ *
+ * Usage:
+ *   node reference-implementation/scripts/repair/gmail-delta-blanked-envelope-restore.ts \
+ *     --connector-instance-id=cin_... [--apply]
+ *
+ * Env:
+ *   PDPP_DATABASE_URL   required (postgres connection string).
+ *                       PDPP_TEST_POSTGRES_URL is accepted as a fallback.
+ *
+ * Exit codes:
+ *   0  dry-run completed, or apply completed successfully.
+ *   1  apply failed (transaction rolled back).
+ *   2  usage / configuration error.

+ * Requeue `too_large` terminal detail gaps whose impossibility proof is
+ * FABRICATED — and only those.
+ *
+ * Why this tool exists separately from `requeue-quarantined-detail-gaps.ts`
+ * -------------------------------------------------------------------------
+ * That tool refuses `too_large` categorically, and correctly so: a `too_large`
+ * row can carry durable per-item proof (an observed byte size recorded
+ * strictly greater than the configured cap), and requeuing a genuinely 29 MB
+ * attachment against a 25 MB cap can never converge — it would spin the
+ * recovery budget forever re-confirming the same impossibility. That refusal
+ * is a safety property, not an oversight, and this tool does not relax it.
+ *
+ * What it turned out to miss is that a `too_large` proof is forgeable by an
+ * ordinary bug. Gmail's attachment hydrator briefly sized attachments from
+ * imapflow's `meta.expectedSize`, which is populated from the FETCH
+ * `RFC822.SIZE` item — the size of the ENTIRE MESSAGE, identical for every
+ * part of a multipart message. Checking that message-scoped number against a
+ * per-part cap condemned EVERY attachment of a message whenever their sum
+ * crossed the cap. On the owner's mailbox that wrote 32 terminal rows sharing
+ * only 7 distinct "observed" sizes, each ≈ the sum of that message's parts;
+ * the smallest item so condemned was 3,080 bytes against a 26,214,400-byte
+ * cap. The connector was fixed to use the per-part BODYSTRUCTURE size, but the
+ * rows it had already written stayed terminal, and `isProvenUnfillableGap`
+ * reads them as durable proof — so the owner is told those emails are
+ * permanently unrecoverable when every one of them is collectible.
+ *
+ * The distinction this tool draws
+ * -------------------------------
+ * A row is requeued ONLY when its claimed size is affirmatively CONTRADICTED
+ * by the item's own recorded size being within the cap. Concretely
+ * (`classifyTooLargeProof` in `server/connector-gap-classification.ts`):
+ *
+ *   - `fabricated_proof`        → requeue. The proof is false.
+ *   - `proof_holds`             → STAYS terminal. The item really is over the
+ *                                 cap; the original refusal was right.
+ *   - `no_corroborating_record` → STAYS terminal, reported separately. Absence
+ *                                 of contradiction is NOT proof of
+ *                                 fabrication; requeuing on missing evidence
+ *                                 would be the same fabrication inverted.
+ *   - `not_a_size_proof`        → STAYS terminal. No parseable numbers, so
+ *                                 there is no size claim to adjudicate.
+ *
+ * So the invariant's PURPOSE is preserved exactly — anything actually proven
+ * unfillable is still refused. What changes is that a proof which independent
+ * evidence shows to be false is no longer honored.
+ *
+ * Why not re-introduce the removed commit 10ed92599 wholesale
+ * -----------------------------------------------------------
+ * That earlier bridge was a Gmail-locked remeasurement path that returned
+ * "unproven" rows to recovery. It keyed off the ABSENCE of proof, which is the
+ * weaker and more dangerous test: under it, a row with no corroborating record
+ * requeues, and the genuinely-oversized rows here (which do carry real proof)
+ * were only excluded incidentally. This tool instead requires positive
+ * contradiction from the item's own durable size, so `no_corroborating_record`
+ * and `proof_holds` both stay terminal for stated reasons rather than as a
+ * side effect of how "unproven" happened to be defined. Restoring the old
+ * bridge would also restore its own copy of the size-vs-cap parsing; the
+ * adjudication here reuses the single shared parser the health projection
+ * already trusts, so the repair tool and the classifier can never disagree.
+ *
+ * Scope + safety model
+ * --------------------
+ *   - Dry-run by default; `--apply` is required to write.
+ *   - Locked to one connector/stream pair, named at invocation time via
+ *     `--connector-id` and never hardcoded here (RI production code carries
+ *     no connector identity — see
+ *     `test/ri-zero-connector-knowledge-conformance.test.ts`): the
+ *     corroborating size (`records.record_json->>'size_bytes'`) is an
+ *     attachment-record shape, and this tool must not guess that shape for a
+ *     connector whose records it has not been reasoned about. The operator
+ *     asserts the connector by passing it explicitly; the tool never infers
+ *     or defaults it.
+ *   - Requires an explicit connector instance id.
+ *   - Every write re-checks `status = 'terminal' AND reason = 'too_large'` and
+ *     targets one gap id, so a row that changed underneath is skipped rather
+ *     than clobbered.
+ *   - Each requeued row keeps an audit trail in `last_error_json`
+ *     (`class: "too_large_proof_contradicted"`) recording the claimed size,
+ *     the cap, and the item's real size — the evidence that justified the
+ *     repair, rather than silently erasing the row's history.
+ *   - Prints counts and per-row verdicts only: gap ids, byte sizes, and
+ *     stream names. No filenames, subjects, addresses, or record payloads.
+ *

+ * durable detail-gap substrate. It exists for the case where a connector or
+ * runtime repair makes it reasonable to retry rows that previously exhausted
+ * a bounded attempt budget and were terminalized under a reason that does
+ * NOT represent durable impossibility.
+ *
+ * `--reason` defaults to `quarantined` (the original, narrower behavior this
+ * tool shipped with) but may name any reason on the store's requeueable
+ * allowlist: `quarantined`, `temporary_unavailable`, `retry_exhausted`,
+ * `run_cap_deferred`. Every one of those is a BOUNDED-BUDGET exhaustion on a
+ * signal that was never proven non-transient — retrying is a legitimate
+ * re-measurement, not wishful thinking.
+ *
+ * Reasons that represent durable impossibility are refused categorically by
+ * the store layer (`assertRequeueableReason` in
+ * `server/stores/connector-detail-gap-store.ts`), not merely left out of a
+ * suggested list here:
+ *   - `not_found` / `gone` / `permanent_forbidden` — proven by an explicit
+ *     non-transient HTTP signal (404/410/permanent-403); the resource is
+ *     confirmed gone, not merely unretried.
+ *   - `too_large` — Gmail's oversized-attachment terminal class. A `too_large`
+ *     row can carry durable per-item proof (observed byte size recorded
+ *     strictly greater than the configured cap). Requeuing a 29 MB
+ *     attachment against a 25 MB cap can never converge — it would spin the
+ *     recovery budget forever confirming the same impossibility. This tool
+ *     has no way to check that per-row proof safely in bulk, so `too_large`
+ *     is refused outright rather than requeued speculatively.
+ *
+ *     If you came here trying to requeue `too_large` rows: that refusal stands,
+ *     and this tool will never accept the reason. A `too_large` proof CAN be
+ *     false (a message-scoped size checked against a per-part cap condemns
+ *     collectible items), but establishing that requires comparing each row
+ *     against the item's OWN recorded size — per-row adjudication this bulk
+ *     path deliberately does not do. Use
+ *     `requeue-fabricated-too-large-detail-gaps.ts`, which requeues a row only
+ *     when its claim is positively contradicted and leaves genuinely-oversized,
+ *     uncorroborated, and unparseable rows terminal.
+ *   - `auth_failure` — requires owner re-authentication, not a data retry.
+ *   - `not_available_in_mode` / `out_of_scope` / `user_disabled` —
+ *     informational, by-design terminal states, not failures to retry.
+ *
+ * See `assertRequeueableReason`'s doc comment for the full reasoning.
  *
  * Safety model:
  *   - Dry-run by default; `--apply` is required to write.
  *   - Requires one explicit connector id and connector instance id.
  *   - Optional `--stream` filters are additive; no payloads or locators print.
+ *   - `--reason` is validated against the store's allowlist BEFORE any read
+ *     or write; an unlisted reason (including `too_large`) fails closed with
+ *     an explanatory error and touches zero rows.
  *   - The implementation's apply path uses the tested detail-gap store
- *     primitive. It does not revive permanent terminal classes such as
- *     `not_found`, `gone`, or `permanent_forbidden`.
+ *     primitive, which re-checks `status = 'terminal' AND reason = <reason>`

+ * transplanted-archive-binding-repair
+ *
+ * Owner/operator-only repair for a manual-upload connection whose
+ * `source_binding_json` was wrapped by an archive transplant and left
+ * pointing at an import directory that does not exist on this host.
+ *
+ * The defect
+ * ----------
+ * When records were transferred off a UAT box, the transfer wrapped each
+ * connection's real binding inside an envelope:
+ *
+ *     { kind: "historical_archive",
+ *       recovery_reason: "uat_record_transfer",
+ *       original_source_binding: { kind: "manual_upload_draft",
+ *                                  import_dir: "<UAT path>", ... } }
+ *
+ * That envelope breaks the run-environment resolver three ways at once:
+ *
+ *   1. `isManualUploadBinding` (server/connection-scoped-run-env.ts) matches
+ *      only a TOP-LEVEL `kind` of `manual_upload` / `manual_upload_draft`.
+ *      A `historical_archive` envelope does not match, so the resolver
+ *      returns null and the connector's import-dir env var is never set.
+ *   2. The wrapped `import_dir` is the UAT host's absolute path
+ *      (e.g. `/var/lib/pdpp/imports/...`), which does not exist here.
+ *   3. The draft hash embedded in that path differs from the hash of the
+ *      directory the artifacts actually landed in on this host, so even
+ *      after re-rooting the prefix the leaf name is still wrong.
+ *
+ * The failure was SILENT: with no env var set, the connector saw no input and
+ * the run reported `source_incomplete` rather than naming a missing path.
+ * (The accompanying server fix makes a missing `import_dir` a legible error;
+ * this tool repairs the bindings that defect already stranded.)
+ *
+ * What it does
+ * ------------
+ * For one connection, it lifts `original_source_binding` to the top level,
+ * restores its `kind` (`manual_upload_draft`), and rewrites `import_dir` to
+ * the directory that actually holds the artifacts on this host. The
+ * replacement path is DISCOVERED by scanning the import root for the
+ * connector's `manual_upload_draft_*` directories — never hardcoded, and
+ * never trusted from the stale binding.
+ *
+ * The envelope's provenance is preserved, not discarded: `recovery_reason`
+ * and `migrated_from_uat_instance_id` are carried onto the repaired binding
+ * so the row still records where it came from, and `repaired_from_kind`
+ * records what it was before this tool ran.
+ *
+ * Discovery + ambiguity
+ * ---------------------
+ * A candidate directory must (a) sit directly under
+ * `<import-root>/<connector>/`, (b) be named `manual_upload_draft_<hash>`,
+ * and (c) contain at least one file somewhere beneath it. If zero candidates
+ * match, the repair refuses. If MORE than one matches, the repair refuses
+ * rather than guessing which archive the owner meant — the operator must
+ * disambiguate with `--import-dir`. Silently picking the newest would be the
+ * same class of guess that produced this mess.
+ *
+ * Safety model
+ * ------------
+ *   - Default is dry-run. `--apply` is required to write.
+ *   - Before any write, the pre-image `source_binding_json` is snapshotted
+ *     into a backup table (prefix `tabr_backup`) inside the SAME transaction
+ *     as the update, so the backup cannot survive a rolled-back write or
+ *     vice versa.
+ *   - The write is guarded on the binding still being the exact
+ *     `historical_archive` envelope that was read, so a concurrent repair or
+ *     an owner re-upload wins instead of being clobbered.
+ *   - Only `source_binding_json` is touched. Status, records, credentials,
+ *     grants, schedule, and spine are never read or written. This tool does
+ *     NOT resume the connection — that is a separate, explicit owner action.
+ *
+ * Output discipline
+ * -----------------
+ * Paths under the import root are operator infrastructure, not record
+ * payload, so they are printed to let the operator verify the target. No
+ * record contents, credentials, or account identifiers are ever read.
+ *
+ * Usage:
+ *   node reference-implementation/scripts/repair/transplanted-archive-binding-repair.ts \
+ *     --connector-instance-id=cin_... [--import-root=/root/.pdpp/imports] \
+ *     [--import-dir=/abs/path] [--apply]
+ *
+ * Env:
+ *   PDPP_DATABASE_URL   required (postgres connection string).
+ *                       PDPP_TEST_POSTGRES_URL is accepted as a fallback.
+ *   PDPP_IMPORT_ROOT    default import root when --import-root is omitted.
+ *
+ * Exit codes:
+ *   0  dry-run completed, or apply completed successfully.
+ *   1  repair refused (nothing to do / ambiguous / missing artifacts), or
+ *      apply failed (transaction rolled back).
+ *   2  usage / configuration error.

+/**
+ * Pure projection of one `/_ref/connectors` connection summary into the rows
+ * the `sources-report` CLI prints.
+ *
+ * WHY THIS EXISTS
+ * ---------------
+ * An agent reading raw `connector_summary_evidence` rows from Postgres is
+ * reading the INPUTS to the health computation. The owner reading `/sources`
+ * is reading the OUTPUT. Those two diverged badly: the agent reported "amber"
+ * where the page said "not measured", and "green data" where the page drew a
+ * red "can't collect" marker. Every rendering-layer defect was invisible to
+ * the agent. This module exists so both read the same OUTPUT.
+ *
+ * WHAT IS AND IS NOT COMPUTED HERE
+ * --------------------------------
+ * The per-source verdict is NOT recomputed. The reference server already
+ * owns it: `rendered_verdict.pill` ({label, tone}) arrives pre-computed over
+ * the wire, and the console does not second-guess it either (see
+ * `apps/console/src/app/(console)/lib/source-actionability.ts`, whose header
+ * records the 2026-07-09 state-model convergence: "There is no client-side
+ * fallback to raw connection-health `state`"). This module reproduces only
+ * the console's own thin presentation step:
+ *
+ *   1. `pill.tone` → the dot glyph and status kind, via the SAME table shape
+ *      the console uses (`VERDICT_TONE_STATUS`), and
+ *   2. the axis keys → owner-facing words, via `@pdpp/display/health`, which is the
+ *      one definition the console imports too.
+ *
+ * A source with no `rendered_verdict` reads an honest "Verdict unavailable" —
+ * never a guess reconstructed from raw axes.

+ * Single choke point for connector-instance canonicalization.
+ *
+ * Production can accumulate multiple `connector_instances` rows for the SAME
+ * real provider account -- most commonly recovered-history fragments
+ * manufactured by a spine-event recovery pass, each with a synthetic
+ * `source_binding_key` that never collides with a sibling fragment's key (see
+ * the live-inventory audit this module was built from,
+ * connector-instance-groups design note). Every fragment stays a fully
+ * independent row: same records, schedules, and credentials columns as any
+ * other connector instance. `connector_instance_groups` (server/db.ts /
+ * postgres-storage.ts) is a pure alias/read-model table recording "fragment X
+ * is the SAME logical account as canonical Y" -- it is the ONLY place that
+ * fact is recorded, and this module is the ONLY place that fact is resolved
+ * back out.
+ *
+ * What this module GUARANTEES:
+ *   - `resolveCanonicalConnectorInstanceId` is a total function: every
+ *     connector_instance_id maps to SOME canonical id (itself, if ungrouped).
+ *   - A canonical id is never itself resolved further (no transitive chains
+ *     -- grouping always targets a terminal canonical row; see
+ *     `assertGroupingTargetIsNotAFragment` in the migration tool).
+ *   - Grouping is data (rows in `connector_instance_groups`), never inferred
+ *     at read time from heuristics (record overlap, provider ids, etc.) --
+ *     this module does not compute overlap or identity proof; it only
+ *     resolves an already-decided mapping.
+ *
+ * What this module explicitly does NOT do (bounded scope of this change):
+ *   - It does NOT rewrite `lexical_search_index` / `semantic_search_blob` /
+ *     `connector_summary_evidence` rows or their read queries. Those surfaces
+ *     still attribute results to the RAW connector_instance_id today. Wiring
+ *     them to call through this resolver is the documented next step (see
+ *     the migration-tool report), not silently claimed as done here.
+ *   - It does NOT decide identity (no record-overlap computation, no
+ *     provider-id comparison). That evidence-gathering lives in the audit /
+ *     migration-tool input, never in this module.
+ *   - It does NOT touch credentials, schedules, or connector_state. A grouped
+ *     fragment keeps whatever it already had (in every proven live case:
+ *     nothing -- paused, uncredentialed) and the migration tool refuses to
+ *     group a fragment that itself carries live credentials or an active
+ *     schedule onto a DIFFERENT canonical id, to avoid orphaning live sync
+ *     state (see `assertFragmentHasNoLiveSyncState`).

+ * Per-unit Postgres statement-timeout floor (design review P1-2): the
+ * cooperative `deadline` this module threads through `discoverCandidates`/
+ * `repairCandidate` is a PASS ADMISSION deadline, checked only BETWEEN
+ * units — it never bounds a single query's own server-side execution (see
+ * `reconcileConnectorSummaryEvidence`'s doc for the reviewer's two-contract
+ * framing). `remainingStatementBudgetMs` derives a `statement_timeout` for
+ * `postgresQueryBounded` from the caller's remaining admission allowance so
+ * a discovery/repair unit's own queries cannot, on their own, silently
+ * consume more than what was left when the unit started (production,
+ * 2026-08-18: `repair_duration_ms: 5322` against a 2000ms pass budget).
+ *
+ * Revised 2026-08-18 after a real production regression: the ORIGINAL 50ms
+ * floor claimed "every query this floor applies to is index-bounded and
+ * normally fast" — that claim was false for the discovery batch's own
+ * `COUNT(*) GROUP BY` over `records`, which had NO index covering `deleted`
+ * (the exact query this whole mechanism existed to bound). That query was a
+ * redundant supplementary drift check — `source_revision` already catches
+ * the same direct-writer-bypass scenario incrementally — and has since been
+ * REMOVED from this hot path entirely (2026-08-18, see `classifyCandidate`'s
+ * doc); this floor and the per-unit bound machinery below remain as general
+ * protection for every OTHER discovery/repair query, which is why they are
+ * kept even though the query that motivated 500ms specifically is gone.
+ * Because the fold phase runs BEFORE discovery/repair in
+ * `runBoundedObservationPhases`
+ * (connector-summary-read-model.ts), discovery routinely starts with little
+ * or no admission allowance left, so `remainingStatementBudgetMs` collapsed
+ * to the 50ms floor on nearly every pass — cancelling that unindexed count
+ * query (which realistically takes low hundreds of ms, not 50) on almost
+ * every attempt. Within minutes this flipped 25 of 29 `connector_summary_
+ * evidence` rows from `current` to `failed` with zero visible error (see
+ * `PostgresStatementTimeoutError` handling below and in
+ * connector-summary-read-model.ts — cancellation is now loud and non-fatal
+ * to already-healthy rows).
+ *
+ * 500ms is a genuine minimum absolute timeout, not merely a "near-zero
+ * allowance" floor: it is chosen to comfortably exceed the unindexed count
+ * query's realistic healthy duration while still being well under the
+ * round's 2000ms pass budget, so a single per-unit cancellation remains
+ * possible for a genuinely pathological/runaway statement. `deadline ===
+ * null` (every caller except the maintenance sweep) is unaffected — those

+/**
+ * Whether a generation advance actually invalidates this row's terminal facts.
+ *
+ * The generation counter is the OUTER, conservative fence: it advances on any
+ * byte of any manifest (`auth.ts` `persistManifestAndAdvanceGenerations`), so
+ * it answers "could this evidence be stale", never "is it". Editing
+ * `capabilities.refresh_policy.recommended_mode` across the fleet advanced 24
+ * generations at once and blanked terminal facts on every one of them, though
+ * the fold reads no such field.
+ *
+ * The declaration fingerprint is the INNER, exact fence. It is the sorted set
+ * of declared stream names (`parseManifestDeclaration`) — precisely the
+ * manifest section the terminal fold depends on. The fold itself reads no
+ * manifest content at all: it folds `collection_facts.streams` off the spine
+ * event, keyed by stream name. The only way a manifest edit can change which
+ * facts are attributable is by changing which streams are declared, which is
+ * exactly what moves this fingerprint. This is the dependency edge Salsa
+ * records by observing a read and Bazel's Skyframe records via `getValue()`;
+ * here the read-set is small and static enough to declare directly.
+ *
+ * So a generation advance is necessary but NOT sufficient: facts are discarded
+ * only when the declaration they were folded under actually changed. This is
+ * the rule the write path already believed it was applying — see the
+ * "A fingerprint transition is the sole exception" note on the upsert's
+ * terminal-facts bindings, which describes this predicate rather than the
+ * generation equality that was actually being tested.
+ *
+ * Fail closed on absence: a NULL stored or incoming fingerprint means the
+ * declaration is unknown for one side of the comparison, so the coarse
+ * generation verdict stands.
+ *
+ * Fail closed on UNOBSERVED generations too, and this is the subtle one. The
+ * fingerprint is a value, not a history, so it cannot distinguish "never
+ * changed" from "changed and changed back". A stream removed and re-added
+ * before any reconcile ran advances the generation twice and returns to a
+ * byte-identical declaration — the classic ABA problem — yet the facts folded
+ * before the removal must not be reattached to the re-added stream. The
+ * monotonic counter is precisely the thing that does not have that blind spot,
+ * so the fingerprint is only trusted to overrule it across a single-step
+ * advance the row actually witnessed. A jump of more than one generation means
+ * at least one declaration state passed unobserved, and an unobserved state is
+ * not evidence of continuity. On the live instance every evidence row tracks
+ * its instance generation exactly, so the ordinary boot-time reconcile path
+ * takes the single-step branch.

+ *      can no longer silently consume more than that unit had left when it
+ *      started. SQLite has NO equivalent — `better-sqlite3` is synchronous
+ *      and exposes no interrupt/progress-handler hook on its public API, so
+ *      a slow SQLite discovery/repair query cannot be cancelled once
+ *      started. This is a disclosed, unclosed gap on SQLite, not a silent
+ *      omission: every hot-path SQLite query in this file is index-bounded
+ *      (`WHERE connector_instance_id IN (...)`/`= ?`, or an indexed
+ *      `MAX`/`GROUP BY` aggregate), so it is expected to be fast in
+ *      practice, but nothing here can force-cancel one that isn't.
+ *   2. FORWARD PROGRESS UNDER STARVATION: even when a discovery unit
+ *      legitimately uses its whole per-unit allowance, `repairCandidates`
+ *      (connector-summary-evidence-bounded-reconciliation.ts) always
+ *      attempts its first selected candidate regardless of the admission

+ * entire shared budget before the cursor ever reaches a later
+ * participant's own high-water — even when that later participant's own
+ * attributable history is short or already fully read. Round-robin gives

+ * turn each rotation, in `ownCursorByInstance` order, so a participant whose
+ * own history is short (or already caught up) converges within its own
+ * first turn or two regardless of how large another participant's backlog
+ * is. A participant already at/above its own high-water (`ownCursor >=
+ * ownMaxSeq`) is skipped entirely — zero read cost, not merely a fast
+ * no-op read — so it cannot be starved of a turn by participants still
+ * mid-backlog.
+ *
+ * Each per-participant read is itself scoped to exactly that one

+ * over.
+ *
+ * This distinction is load-bearing, not cosmetic (production, 2026-08-18):
+ * with a backlog SMALLER than one page (e.g. 8 dirty ids against a 25-id
+ * page limit), advancing to the last FETCHED id committed the cursor to id
+ * #8 every round regardless of how many candidates the deadline actually let

+ * only #1 again, and reported alternating `repaired: 1` / `repaired: 0`
+ * while ids 2-8 were never attempted and the backlog never drained. The same
+ * class of gap exists for a backlog LARGER than one page: a permanently
+ * expired deadline advancing on "fetched" cycles through ids 1, 26, 51,
+ * 76, ... forever, since each page's fetch always reaches its full width
+ * even when the deadline lets almost none of it be attempted. Advancing on
+ * "attempted" instead means a page that only manages to attempt its first
+ * candidate rotates the cursor just past THAT candidate, so the next round's
+ * page starts at candidate #2 rather than re-fetching the identical prefix.
+ *
+ * Advancing to the last ATTEMPTED id preserves the original "never wedge on
+ * a permanently-failing page" property this cursor exists for: an attempt
+ * that fails, throws, or is deferred still counts as attempted (see
+ * `repairCandidates`'s `attemptedIds`), so a candidate that will never
+ * succeed still gets rotated past exactly like a candidate that succeeds —
+ * only a candidate NEVER GIVEN A TURN this round stays at the front of the
+ * next page.
+ *
+ * `null` when there is nothing to resume from (either the tranche has never

+ * (connector-summary-evidence-engine.ts, `canonicalResult`) -- was judged

+ * records out of 5.46M total), this query took 3.67-4.07 SECONDS each,
+ * `Parallel Seq Scan`-ing ~584k buffers (~4.5 GB) -- none of `records`'
+ * existing seven indexes cover `(connector_instance_id, deleted)` without a
+ * `stream` predicate this GROUP-BY query cannot supply. Both connections
+ * were repeatedly selected as repair candidates, cancelled by the per-unit
+ * `statement_timeout` floor every pass, and left `dirty` forever: the
+ * existing per-connection catch (`reasonCodeForRepairFailure`/
+ * `logRepairFailure`) correctly avoids marking evidence `failed` on a
+ * cancellation, but "correctly deferred, forever, on the same two rows" is
+ * still an unbounded backlog, not a fix.
+ *
+ * REJECTED alternatives (see connector-summary-evidence-lifecycle-seq-index
+ * test file's sibling investigation and this commit's message for the full
+ * comparison): raising `MIN_STATEMENT_TIMEOUT_MS`, or giving repair a larger
+ * bound than discovery, both re-trap on the NEXT connection to cross
+ * whatever new ceiling is picked -- this query's cost is O(row count) with
+ * no upper bound, so any fixed timeout is a matter of when, not if. A
+ * maintained counter (`retained_size_stream.record_count`, already
+ * incrementally upserted on every write) was close but rejected as the
+ * primary fix: it carries no `last_updated`/`MAX(emitted_at)` column at all
+ * (a schema change of its own), and its row-presence semantics differ from
+ * this sparse `GROUP BY` in a way `buildRepairedRow`'s `known_zero` vs
+ * `unobserved` distinction depends on -- reusing it would change repair's
+ * classification logic, a larger and riskier change than closing an
+ * honestly-measured index gap.
+ *
+ * This index closes the gap the SAME way as this table's other five
+ * `connector_instance_id`-leading indexes above: `(connector_instance_id,
+ * deleted, stream)` matches the query's WHERE + GROUP BY columns exactly,
+ * `INCLUDE (emitted_at)` lets the MAX() aggregate read directly from the
+ * index without a further heap lookup for that column. Verified directly
+ * (production-representative selectivity: one connection at ~4.4% of a
+ * 5.46M-row table, matching the real `cin_2de5ede05c8cc8d45935c414`/total
+ * ratio, seeded and measured in a throwaway scratch database, never
+ * production DDL): the SAME query plans a `Bitmap Heap Scan` off this
+ * index post-VACUUM at 83.7ms, versus the 4.07s unindexed `Parallel Seq
+ * Scan` measured on live production data -- and no change to
+ * `canonicalResult`'s shape or `buildRepairedRow`'s consumption of it.
+ *
+ * SCOPE OF THAT MEASUREMENT, stated honestly: the 83.7ms figure is at ONE
+ * connection holding ~4.4% of the table. This index helps in proportion to
+ * how SELECTIVE the connection is, and a covering index stops being the
+ * cheaper plan once a single connection owns a large fraction of `records`
+ * -- past roughly a third, the planner correctly prefers a sequential scan
+ * and this index will simply be ignored. That is not a defect in the index;
+ * it is the point at which "read this one connection's rows" and "read the
+ * whole table" converge. So this closes the gap for the fleet's normal
+ * shape (many connections, each a small slice) and does NOT by itself
+ * guarantee every future connection stays inside
+ * `MIN_STATEMENT_TIMEOUT_MS`. A connection that grows to dominate the table
+ * needs a bounded/resumable read, not a wider index or a bigger timeout.

+ * defects compounded; this index closes the larger, and it closes it on BOTH
+ * sides of that incident, which is the part worth stating plainly.
+ *
+ * The keyset-pagination shape `WHERE connector_instance_id = $1 AND stream =
+ * $2 AND deleted = FALSE AND id > $3 ORDER BY id ASC LIMIT $4` had no index
+ * that could serve it. `records`' seven existing indexes all lead with
+ * `connector_instance_id` but none carries `id` as the column immediately
+ * after the equality predicates, so none can satisfy the ORDER BY. The
+ * closest, `idx_pg_records_stream_cursor`, is `(connector_instance_id,
+ * stream, deleted, cursor_value, primary_key_text)` — its fourth column is
+ * `cursor_value`, not `id`. The planner therefore fell back to `records_pkey`
+ * (already `id`-ordered, so the sort is free) and filtered every
+ * non-matching row away one at a time.
+ *
+ * Measured directly against production (READ-ONLY, `EXPLAIN (ANALYZE,
+ * BUFFERS)`) for `cin_12407c1afb78d56848fe0b20`/`messages` — 140,689 live
+ * rows in a 5.61M-row table: 27.4 SECONDS to return 50 rows, `Index Scan
+ * using records_pkey`, `Rows Removed by Filter: 3,031,420`, reading 514,958
+ * buffers from disk (~4 GB against a 512 MB `shared_buffers`). The row count
+ * removed is the whole story: the scan must walk every row with a lower `id`
+ * than the target connection's first row before it can return anything.
+ *
+ * This is NOT only a page-load defect. `postgresSemanticRecordsPage`
+ * (postgres-search.ts) — the coverage-scan SELECT that feeds the semantic
+ * backfill — issues the IDENTICAL query shape with `LIMIT 500`, and live
+ * `pg_stat_activity` sampling during a real re-ingest caught it at 1.2s,

+ * the "bulk ingest freezes the console" symptom and the "source detail page
+ * is slow" symptom were substantially the same missing index, hit from two
+ * call sites — the bulk pager was not merely competing for resources, it was
+ * itself running multi-second statements for the same reason. Fixing the
+ * index bounds both.
+ *
+ * Verified in a throwaway scratch database (never production DDL), seeded to
+ * production-representative shape — 3,031,420 rows belonging to other
+ * connections occupying the low `id` range, then 140,689 target rows, which
+ * reproduces the exact `Rows Removed by Filter: 3031420` from the live plan:
+ * the `LIMIT 50` page query goes 558ms -> 0.089ms, and the `LIMIT 500` bulk
+ * coverage page goes to 1.4ms, both switching to `Index Scan using
+ * idx_pg_records_instance_stream_id` with all four predicates absorbed into
+ * `Index Cond` and zero rows removed by filter.
+ *
+ * SCOPE, stated honestly: the scratch measurement's absolute numbers are
+ * smaller than production's because the scratch table has narrow rows and a
+ * warm cache; what transfers is the PLAN CHANGE and the elimination of
+ * `Rows Removed by Filter`, not the millisecond figure. The improvement is
+ * proportional to how deep the target connection's rows sit in the `id`
+ * space — a connection whose rows start near `id = 0` was never slow and
+ * gains little. Correspondingly, this index does not help any query that
+ * cannot supply both `connector_instance_id` and `stream` as equalities.
+ *
+ * REDUNDANCY: none. All seven pre-existing `records` indexes show non-zero
+ * `idx_scan` in `pg_stat_user_indexes` on production (lowest:
+ * `idx_pg_records_semantic_time` at 2,208), so nothing is dropped here. This
+ * index is additive — it does not prefix-subsume `idx_pg_records_stream_cursor`
+ * (that one's `cursor_value`/`primary_key_text` tail serves a different
+ * pagination) nor `idx_pg_records_canonical_count` (different column ORDER:
+ * `(instance, deleted, stream)`, plus `INCLUDE (emitted_at)`).
+ *
+ * Built `CONCURRENTLY` for the same reason as
+ * `idx_pg_records_canonical_count` above: `records` holds 5.6M rows / 4.6 GB
+ * on production, and a plain `CREATE INDEX` would hold a table-wide write
+ * lock for the entire build against the owner's live instance.

+/**
+ * Fail-closed admission guard for real-Postgres TEST lanes.
+ *
+ * Background (the incident this exists to prevent): a Postgres-backed test
+ * read `PDPP_TEST_POSTGRES_URL` and called `initPostgresStorage` directly
+ * against it, provisioning no scratch database of its own. Someone ran that
+ * file with the variable pointed at the PRODUCTION database. The suite wrote
+ * 42 stray rows across 12 connector instances into real owner data. That was
+ * the MILD outcome: these suites also do destructive setup (DELETE/TRUNCATE
+ * of the streams they exercise), so the same hole could have destroyed real
+ * records rather than merely littering them.
+ *
+ * WHY A SENTINEL AND NOT A BLACKLIST
+ *
+ * The tempting fix is to refuse known-production URLs (host, port, database
+ * name). That fails OPEN: it only refuses the production spellings someone
+ * remembered to enumerate. A new host, a container remap, a connection made
+ * through a different port forward, a restored copy of production under
+ * another name -- each sails straight through a blacklist, and the failure is
+ * silent data loss. A URL-shape allowlist (`dedicatedPostgresTestUrl`) is
+ * better and stays in force at the runner boundary, but it still only proves
+ * the URL *looks* like a test URL. It cannot prove the database *behind* that
+ * URL is a scratch database: the dedicated test listener also hosts hand-made
+ * databases, and nothing stops a production database from being reachable at
+ * a test-shaped address (a port-forward to :55447 is one command).
+ *
+ * So authority here is derived from the DATABASE'S OWN CONTENTS, not from its
+ * address. A test database must carry a sentinel table this module writes,
+ * and no admission is possible without it:
+ *
+ *   1. POSITIVE MARKER (fail-closed). The target must contain the sentinel
+ *      table `pdpp_test_guard.pdpp_test_database_sentinel` with a matching
+ *      marker row (its own schema, so a suite that legitimately runs
+ *      `DROP SCHEMA public CASCADE` does not erase its own admission). A
+ *      database nobody explicitly provisioned as a test database has no
+ *      sentinel, so it is REFUSED BY DEFAULT. Production has no sentinel and
+ *      can never acquire one by accident -- only `provisionTestDatabase()`
+ *      writes it, and that function refuses to run against a database holding
+ *      real data (see 2). Absence of evidence is refusal, which is what makes
+ *      this fail closed: the unknown case is the refused case.
+ *
+ *   2. REAL-OWNER-DATA REFUSAL (defense in depth). Even WITH a sentinel, the
+ *      target is refused if `public.records` is non-empty at admission time,
+ *      i.e. it holds data this run did not create.
+ *      This closes the residual path where a sentinel is stamped onto a
+ *      database that already holds real data (a restored production dump, or
+ *      a production database someone stamped by hand). Marker and data must
+ *      agree; disagreement is refusal.
+ *
+ * Both checks run BEFORE any pool is opened for writing, and a refusal throws
+ * a loud, immediate, named error. There is deliberately NO silent-skip path:
+ * a skip would let CI go green while covering nothing, which is how a hole
+ * like this survives. Refusal is an error, never a skip.
+ *
+ * The guard is scoped to test execution. It activates only for a process that
+ * declares itself a test lane (`PDPP_TEST_POSTGRES_URL` set, or an explicit
+ * `PDPP_REQUIRE_TEST_DATABASE=1`); the product's own production boot is
+ * untouched and never consults it.

+ * The owner-facing display name for one configured connection.
+ *
+ * B8 (owner ledger 2026-08-22). ONE RULE, stated once: **a source's label must
+ * identify WHICH source it is.** Two owner complaints are the same defect:
+ *
+ *   1. A local-device source's stored `display_name` is whatever the owner typed
+ *      into the enrollment form's free-text field, passed through verbatim as
+ *      `--device-label`. Nothing ever composed the connector name into it, so
+ *      the owner typed "peregrine Codex" by hand but only "peregrine" for
+ *      Signal — a bare hostname saying nothing about WHAT it collects.
+ *      (Owner: "it should have been called 'signal' then".)
+ *
+ *   2. Two Amazon connections both rendered as literally "Amazon", so the owner
+ *      could not tell which account survived a tombstoning.
+ *      (Owner: "I only see one Amazon source... I don't know which one remains,
+ *      and I don't know where the other one went.")
+ *
+ * Both are answered by the same composition, applied in identity order —
+ * the label carries the connector, then whatever distinguishes this connection
+ * from its siblings of the same connector:
+ *
+ *   - device-backed  →  "<device> <Connector>"        e.g. "peregrine Signal"
+ *   - account-backed →  "<Connector> - <account>"     e.g. "H-E-B - a@b.com"
+ *
+ * The account identifier is the manifest-declared, NON-SECRET identity field
+ * (`verified_identity` on `source_binding`, read via the provider-neutral
+ * `staticSecretVerifiedIdentityFromBinding`). The `identity: true` +
+ * `secret: false` pair is the manifest's own declaration that a field is a safe
+ * account label rather than a credential — so a connector that marks its
+ * username `secret: true` (H-E-B does) can never leak it through this path.
+ * Provider-neutral: no connector is named here.
+ *
+ * HONESTY / SCOPE: when a connection exposes no declared account identity this
+ * does NOT invent one, and it does NOT decorate the label with an opaque id by
+ * default. Most connectors (including Amazon) declare no identity field today,
+ * so the honest fix for two identically-named Amazon rows is upstream — the
+ * connector must declare an identity field, or the owner renames the
+ * connection. Inventing a distinguishing suffix here would manufacture the
+ * appearance of identity the system does not actually have. See the report for
+ * what this does and does not close.
+ *
+ * Derived at RENDER time, never stored, because:
+ *   1. The owner's typed label is their data. Rewriting
+ *      `connector_instances.display_name` would silently restate an
+ *      owner-authored name and make the owner's own rename
+ *      (`owner-connections.ts` `setDisplayName`) indistinguishable from a
+ *      machine edit.
+ *   2. It fixes EXISTING rows and future enrollments in one step — no
+ *      migration, nothing to reverse.
+ *   3. Every input is already on the projected row; no join, no extra read.
+ *
+ * PII: an account identifier in a display name is the existing shipped pattern
+ * (H-E-B). It stays confined to this owner-facing label — never logs, never
+ * diagnostics.

+ * Whether a pending detail gap is a **local-collector runner condition** rather

+ *
+ * B9 (owner ledger 2026-08-22): the detail-gap store is keyed by stream, but a
+ * local-collector gap is not stream-scoped — `connector_child_failure` means the
+ * collector's child process died, and `policy_budget` means it hit a scan
+ * budget. Neither has a stream. To fit the stream-shaped primary key,
+ * `parseGapBodyBase` (`routes/ref-device-exporters.ts`) mints a synthetic name
+ * like `local-collector/connector_child_failure` and stores it in the `stream`
+ * column. Unfiltered, that pseudo-stream flowed into the collection report's
+ * in-scope universe and the console rendered a PROCESS FAILURE as one of the
+ * owner's DATA STREAMS.
+ *
+ * The gap already carries the structured discriminator the route wrote next to
+ * the synthetic name: `detail_locator.kind === "local_collector_gap"`. We key on
+ * that (not on the stream-name prefix) because it is the authored field and is
+ * immune to separator drift between emitters.
+ *
+ * This ONLY removes the failure from the per-stream data list. The failure still
+ * reaches the owner through the channel that already carries it: the
+ * `local_collector_gaps` diagnostics block, which aggregates the pending count
+ * and the `reasons` array and renders with a warning tone

+// Pause is the inverse of resume (`owner-connection-resume.ts`): it flips a

+// lands for it. Already-collected records, grants, schedule rows, the stored

+// status flip on the connector-instance row, zero cascade.
+//
+// Why pause exists alongside revoke: revoke is the durable "stop collecting
+// from this account, I am done with it" act, and its inverse (`reactivate`)
+// is deliberately an explicit re-initiate. Pause is the reversible, low-stakes
+// "stop collecting for now, keep everything" act — the owner keeps the
+// connection, its credential, and its history, and resumes when ready. Before
+// pause existed as an ACTION, `paused` was a state the system could land a row
+// in (e.g. a recovered historical-archive transplant) but that no owner could
+// ever deliberately produce, which made the resume half of this pair reachable
+// only by accident.
+//
+// Key design choices that mirror `owner-connection-resume.ts`:
+//   - Same auth adapter: `requireToken` + `requireOwner` (bearer owner-kind).
+//   - Same resolver (`resolveOwnerConnectorNamespace`), with
+//     `allowStatuses: ['active']` so only a collectible connection can be
+//     paused. A foreign/unknown id surfaces as `connector_instance_not_found`
+//     (404); an already-paused (or revoked, or draft) connection surfaces as
+//     `connector_instance_inactive` (400) from the resolver, which the caller
+//     re-labels as `connector_instance_not_active` (409) so a repeat pause is
+//     a clean typed no-op rather than an opaque 400.
+//   - Same ambiguity path on the connector-only route
+//     (`ambiguous_connector_instance` -> `ambiguous_connection` 409).
+//   - Same audit event family shape, named `owner_agent.connection.pause`.
+//   - `updateConnectorInstanceStatus` with `status: 'paused'` flips the row;
+//     `revokedAt` is left `null` (pausing is not revoking, so there is nothing
+//     to set — a paused row must never read as revoked on any surface).

+// Resume is the `paused`-status sibling of `reactivate` (which is the clean
+// inverse of revoke, `revoked` -> `active`): it flips a single `paused`
+// connection back to `active`, so the connection becomes runnable again.
+// Already-collected records, grants, schedule, and audit are never touched —
+// the transition is a pure status flip on the connector-instance row, zero
+// cascade.
+//
+// The shared `applyResume` primitive below is the only deliberate status
+// transition that moves a connection from `paused` to `active`; the session
+// route and credential-repair hooks reuse it rather than maintaining another
+// status-flip implementation. Before this route existed, `paused` had a
+// schema-valid
+// enum value and read-path tolerance (setup-status, owner ingest) but no
+// write path ever produced it AND no write path ever resumed it — a
+// connection paused by an out-of-band operation (e.g. a recovered
+// historical-archive row with no surviving credential, restored with
+// `status: 'paused'` specifically because reactivating it as `active` with no
+// credential would be unsafe) had no way back to `active` even after the
+// owner re-sealed a working credential via the static-secret credential
+// capture route. Resume closes that gap without inventing a new cascade:
+// exactly like reactivate, it does not validate or re-supply credentials —
+// the owner is expected to have already repaired the credential (e.g. via
+// `POST /_ref/connections/:id/static-secret-credential`, which now admits a
+// `paused` target) before calling resume. A resumed connection whose stored
+// credential is still missing/invalid surfaces a typed credential error on
+// its NEXT collection run, same as any other auth failure.
+//
+// Key design choices that mirror `owner-connection-reactivate.ts`:
+//   - Same auth adapter: `requireToken` + `requireOwner` (bearer owner-kind).
+//   - Same resolver (`resolveOwnerConnectorNamespace`) but with
+//     `allowStatuses: ['paused']` so the active-status gate is replaced by a
+//     paused-status gate. This means a foreign/unknown id still surfaces as
+//     `connector_instance_not_found` (404) and an already-active (or revoked,
+//     or draft) connection surfaces as `connector_instance_inactive` (400)
+//     from the resolver, which the caller then re-labels as
+//     `connector_instance_not_paused` (409).
+//   - Same ambiguity path on the connector-only route
+//     (`ambiguous_connector_instance` -> `ambiguous_connection` 409).
+//   - Same audit event family shape, named `owner_agent.connection.resume`.
+//   - `updateConnectorInstanceStatus` with `status: 'active'` flips the row;
+//     `revokedAt` is left `null` (a paused row is never revoked, so there is
+//     nothing to clear).

+ * Terminal `reason` values this repair tool is allowed to reopen, and why.
+ *
+ * Every value here means "the terminal state can plausibly have been caused
+ * by a connector/runtime defect that has since been fixed" — retrying is a
+ * legitimate re-measurement, not wishful thinking:
+ *   - `quarantined`   — a per-item no-progress budget was exhausted without
+ *     ever recording a reason (the original defect this tool was built for).
+ *   - `temporary_unavailable` — the row's own class name says "this may
+ *     resolve"; it was terminalized only because it exhausted a bounded
+ *     attempt budget while looking transient, not because of any proof of
+ *     permanence.
+ *   - `retry_exhausted` / `run_cap_deferred` — same shape: a bounded budget
+ *     ran out on a signal that was never non-transient.
+ *
+ * Deliberately EXCLUDED — durable-impossibility reasons a bulk reopen must
+ * never touch:
+ *   - `not_found` / `gone` / `permanent_forbidden` — `classifyRecoveryError`
+ *     (server/stores/terminal-gap-classifier.ts) only assigns these from an
+ *     explicit non-transient HTTP signal (404/410/permanent-403). Reopening
+ *     a proven-gone resource just re-wastes the recovery budget confirming
+ *     it is still gone.
+ *   - `too_large` — Gmail's `AttachmentTooLargeError` terminal class. A
+ *     `too_large` row can carry durable per-item proof (observed byte size
+ *     recorded strictly greater than the configured cap — see
+ *     `isProvenUnfillableGap` in `server/connector-gap-classification.ts`):
+ *     requeuing a 29 MB attachment against a 25 MB cap can never converge,
+ *     it would just spin the recovery budget forever. This generic bulk
+ *     path has no way to check that per-row proof safely, so the reason is
+ *     refused categorically rather than requeued speculatively. (A prior,
+ *     narrowly-scoped one-off bridge — `too_large` + unproven rows only,
+ *     Gmail/attachments-locked — existed for exactly this distinction; see
+ *     commit 10ed92599. That per-row-proof check does not exist on this
+ *     branch, so this tool does not attempt to replicate it.)
+ *   - `auth_failure` — requires owner re-authentication, not a data retry;
+ *     silently requeuing it would not fix anything and would mask that the
+ *     owner still needs to act.
+ *   - `not_available_in_mode` / `out_of_scope` / `user_disabled` —
+ *     informational, by-design terminal states, not failures to retry.

+/**
+ * Pins the two connection-scoped static-secret resolvers to one contract.
+ *
+ * There are two structurally identical implementations of the same resolver:
+ *
+ *   - `server/connection-scoped-run-env.ts` — the leaf module, used by
+ *     `scheduler-manager-factory.ts` and the reference test suite.
+ *   - `server/index.ts`'s `buildControllerStaticSecretRunEnvResolver` — the
+ *     one the LIVE server installs for BOTH the controller path (manual runs,
+ *     `/_ref/run-now`) and the scheduler path (automatic runs).
+ *
+ * They drifted. The leaf module forwarded `isStaticSecretCaptureOptional` to
+ * `resolveStaticSecretRunEnv`; the `index.ts` copy did not. Because only the
+ * `index.ts` copy runs in production, the drift was invisible to every existing
+ * test — `static-secret-run-credentials.test.ts` proves the SEAM honors the
+ * argument, but nothing proved the live caller passes it.
+ *
+ * Consequence of the omission: `resolveStaticSecretRunEnv` treats a missing
+ * credential as a soft `null` (proceed without an env fragment, let the
+ * connector fall back to manual sign-in) under EITHER of two conditions —
+ * a browser-session `sourceBinding.kind`, or the connector's manifest
+ * declaring `credential_capture.required: false`. With the second condition
+ * unreachable on the live path, a `captureRequired: false` connector (venmo)
+ * bound as anything other than `browser_collector` /
+ * `browser_enrollment_shell` — for instance a `historical_archive` binding —
+ * hit the store's throw and had its run REFUSED, instead of starting and
+ * offering the owner the manual sign-in the manifest explicitly promises.
+ *
+ * This test asserts the argument set itself rather than an end-to-end run, so
+ * it stays a fast unit test with no DB or spawn, and it fails loudly the
+ * moment either implementation stops forwarding a resolver argument the other
+ * one forwards.

+ *   - ChatGPT/Gmail: partial key overlap -- overlap alone must never be

+ *   - Pagination: `loadOwnerConnectorInstanceGroupsSqlite` must return every

+/**
+ * Fairness defect in `runDirtyPriorityAcceleration`'s rotation cursor
+ * (`nextDirtyAfterId`, connector-summary-read-model.ts), identified by an
+ * independent design reviewer and CONFIRMED live on production (2026-08-18).
+ *
+ * Before this fix, the cursor advanced to the LAST FETCHED id
+ * (`dirtyIds.at(-1)`) BEFORE `observeConnectorSummaryEvidence` ever ran —
+ * committed regardless of how many of those fetched ids the round's
+ * deadline actually let `repairCandidates` attempt. `repairCandidates`
+ * only guarantees candidate #1 a turn once the deadline has already
+ * expired (the "repair at least one" floor closed 2026-08-18); every
+ * candidate AFTER #1 is skipped once expired.
+ *
+ * Counterexample A (backlog SMALLER than the page limit — the live
+ * production case): 8 dirty ids, page limit 25. Every round fetches all 8,
+ * commits the cursor to id #8, then (under sustained load) the deadline
+ * expires during/after discovery so only candidate #1 is attempted.
+ *
+ * NOTE ON `readDirtyInstanceIdPage`'s existing wraparound: the SQLite/
+ * Postgres store's `listDirtyInstanceIds` ALREADY silently re-fetches from
+ * the start whenever an `afterId`-filtered query returns empty (see its
+ * "Wraparound" comments) — this is pre-existing behavior, not part of this
+ * fix. That wraparound means a merely-past-the-end cursor is harmless on its
+ * own: it does not, by itself, wedge a backlog smaller than one page. The
+ * genuine wedge (empirically verified against the reverted pre-fix source
+ * before any test below was written) requires the SAME candidate to be
+ * re-selected as "the" guaranteed-first candidate every round — which
+ * happens whenever that candidate's own repair never clears its dirty flag
+ * (fails or is deferred). Every test below that targets this cursor uses a
+ * genuinely FAILING poisoned candidate (`poisonCandidate`) for exactly this
+ * reason — an always-succeeding candidate set converges at the same rate
+ * whether the cursor tracks "fetched" or "attempted", because the
+ * wraparound papers over the fetched/attempted gap once nothing ahead of
+ * the cursor remains dirty.
+ *
+ * Counterexample B (backlog LARGER than the page limit): with 100 dirty
+ * ids and page size 25, a permanently expired deadline attempts id 1, 26,
+ * 51, 76, then id 1 again forever — ids 2-25, 27-50, etc. never become
+ * first and never run. Here the wedge does NOT need a poisoned candidate to
+ * reproduce (a full page's `dirtyIds.at(-1)` is a REAL later id, not an
+ * artifact of the wraparound) — but this suite poisons the same 4 positions
+ * anyway so the discriminator (which ids get serviced) is unambiguous
+ * rather than merely "how many rounds until eventual convergence" (both
+ * pre-fix and post-fix eventually converge at the SAME rate when every
+ * candidate always succeeds — see the empirical trace in this defect's
+ * fix-and-report notes).
+ *
+ * The fix: advance the cursor to the last id the round genuinely ATTEMPTED
+ * (repair was invoked, whether it then succeeded, failed, or was
+ * deferred) — never merely the last id FETCHED. See
+ * `lastAttemptedDirtyId`/`runDirtyPriorityAcceleration`'s doc in
+ * connector-summary-read-model.ts.
+ *
+ * Every fleet here uses a lexicographically LATER `connectorId` prefix
+ * ("z...") than a large sibling fleet ("a..."), so the cursor WALK's own
+ * page(s) (ordered `connector_instance_id ASC` across the COMPLETE
+ * canonical set) stay inside the sibling prefix and never repair the
+ * dirty targets "for free" — isolating the ACCELERATION tranche's own
+ * fairness behavior, which is what this defect is in.

+ * with every maintenance-sweep pass reporting
+ * `repaired: 0, incomplete: true, duration_ms` 2-3.5x over its 2000ms
+ * budget. Root cause: `runScopedConnectorReconciliation`'s `discover(ids)`
+ * call is NOT deadline-checked (it is one indivisible batched read, not a
+ * per-candidate loop) — a discovery read slow enough to exceed the round's
+ * entire budget (contention from unrelated heavy I/O in production) left
+ * `Date.now() >= deadline` already true before `repairCandidates`'s loop
+ * ever called `repair()` for candidate #1, so EVERY selected candidate was
+ * reported `skipped` with zero attempts, every round, forever — the exact
+ * backlog-is-stable-not-draining shape observed live (dirty stayed at 16,
+ * repaired stayed 0, over a 110s window).
+ *
+ * The fix (`connector-summary-evidence-bounded-reconciliation.ts`'s
+ * `repairCandidates`): the FIRST selected candidate is always attempted
+ * regardless of the deadline — a discovery read that already consumed the
+ * round's real time must not also forfeit the one repair unit that work
+ * was for. Every candidate after the first still obeys the ordinary
+ * cooperative-deadline contract.

+ * This file proves the fix directly at `runScopedConnectorReconciliation`,

+ * Production incident, 2026-08-18 (second incident against the SAME
+ * discovery query commit c7da5ea94/1d8995b0f already hardened): the
+ * maintenance sweep reported `consecutiveNoProgressPasses` climbing past 28
+ * while `eligibleBacklog` sat pinned at 8, with EVERY round reporting
+ * `repaired: 0` AND `skipped: 0` (not merely `skipped > 0`, which would mean
+ * candidates were selected and deferred — `skipped: 0` means candidate
+ * selection itself never ran).
+ *
+ * Root cause, traced to file:line: `readPostgresDiscoveryContext`
+ * (connector-summary-evidence-engine.ts) issues the canonical
+ * `records`-count aggregate (`canonicalCountResult`) as one of seven
+ * SEQUENTIAL `postgresDiscoveryQuery` calls, all sharing one un-isolated
+ * try/catch inside `discoverCandidates`. On this instance's real data
+ * volume, that ONE query (`SELECT connector_instance_id, COUNT(*) FROM
+ * records WHERE deleted = FALSE AND connector_instance_id = ANY(...) GROUP
+ * BY ...`) measured 4-7 SECONDS via `EXPLAIN ANALYZE` for connections with
+ * millions of live records — far beyond even the `MIN_STATEMENT_TIMEOUT_MS`
+ * = 500ms floor 1d8995b0f raised it to. Every pass, that query was
+ * cancelled by Postgres's `statement_timeout` (57014), threw a
+ * `PostgresStatementTimeoutError`, and that error propagated straight past
+ * `discoverCandidates` — aborting classification for the ENTIRE requested
+ * batch, before `classifyCandidate` ever ran for ANY row, including rows
+ * that are unambiguously `dirty` (`classifyCandidate` returns `"dirty"`
+ * on its FIRST comparison, long before it would ever reach the canonical-
+ * count comparison this cancelled query feeds). `observeConnectorSummaryEvidence`
+ * correctly treats that as "discovery cancelled, retry next pass, don't
+ * mark evidence failed" (1d8995b0f's own fix) — which is exactly why
+ * nothing was ever marked `failed`, but it also means nothing was ever
+ * `attempted`: `attemptedIds: []`, so `repairCandidates` never ran, so
+ * `repaired: 0` AND `skipped: 0` forever, for a backlog that never shrinks.
+ *
+ * This file proves, against REAL PostgreSQL (a mock cannot prove Postgres
+ * itself cancels the statement, and cannot prove the fix's fail-soft catch
+ * is scoped to exactly the one slow query rather than the whole batch):
+ *   - FAIL-BEFORE: a genuinely cancelled canonical-count read aborts
+ *     discovery for the WHOLE requested batch, so an unambiguously dirty
+ *     row is never even attempted and its `dirty` flag never clears. (This
+ *     reproduces the OLD code shape directly against the query primitive —
+ *     the query itself no longer runs inside `discoverCandidates` at all,
+ *     see the next bullet.)
+ *   - PASS-AFTER (current code, 2026-08-18 root-cause fix): the isolated
+ *     catch above was kept as defense in depth, but the canonical-count
+ *     query it isolates has been REMOVED from `readPostgresDiscoveryContext`
+ *     entirely — it was strictly redundant with `connector_instances.
+ *     source_revision` (advanced incrementally by a row-level trigger on
+ *     every write to `records`, catching the identical "direct writer
+ *     bypassed the version-allocating ingest path" scenario without ever
+ *     scanning `records`). Contending `records` therefore no longer affects
+ *     discovery AT ALL: a dirty row in the same batch still classifies and
+ *     repairs normally, and — unlike the old isolated-but-still-run shape —
+ *     no "canonical record-count discovery cancelled" log line is possible
+ *     any more, because that query is never issued by discovery. See
+ *     `classifyCandidate`'s doc in connector-summary-evidence-engine.ts for
+ *     the full root-cause rationale.

+ * Production incident, 2026-08-18, DEPLOYED image `pdpp-core:drain10`
+ * (commits a5505bb59 and this branch's own `idx_pg_spine_events_
+ * instance_seq` discovery-side fix, both confirmed live and working):
+ * `candidates_inspected: 0` fell to zero, discovery's own cancellations
+ * disappeared from the Postgres log -- but the dirty backlog still never
+ * shrank. Postgres logs showed a THIRD shape: 9 statement_timeout
+ * cancellations in 10 minutes, all in the REPAIR path (`"repair for
+ * <id> cancelled by Postgres statement_timeout"`, not `"discovery
+ * cancelled"`), and always the SAME two connections --
+ * `cin_2de5ede05c8cc8d45935c414` (peregrine Claude Code, 2.42M records) and
+ * `cin_ece4bfe5096b8bf67a1468c2` (peregrine Codex, 1.30M records), together
+ * ~3.7M of the fleet's 5.46M total rows in `records`.
+ *
+ * Root cause: `repairCandidatePostgres`'s per-connection canonical read
+ * (connector-summary-evidence-engine.ts, `canonicalResult`) --
+ *
+ *   SELECT stream, COUNT(*)::int AS record_count, MAX(emitted_at) AS last_updated
+ *     FROM records WHERE connector_instance_id = $1 AND deleted = FALSE
+ *    GROUP BY stream
+ *
+ * -- was judged "legitimate, necessary, cheap" earlier in this same
+ * investigation WITHOUT measuring it against a real multi-million-row
+ * connection. Measured directly against production (READ-ONLY, `EXPLAIN
+ * (ANALYZE, BUFFERS)`): 4.07s / ~584k buffers (~4.5 GB) for
+ * cin_2de5ede05c8cc8d45935c414, 3.67s for cin_ece4bfe5096b8bf67a1468c2 --
+ * `records` has SEVEN existing indexes, none of which cover
+ * `(connector_instance_id, deleted)` without a `stream` predicate this
+ * GROUP-BY query cannot supply (the closest, `idx_pg_records_stream_cursor`,
+ * puts `deleted` AFTER `stream` in its key order). The existing
+ * per-connection catch (`reasonCodeForRepairFailure`/`logRepairFailure`,
+ * 2026-08-11) correctly avoids marking evidence `failed` on a cancellation
+ * -- exactly why nothing was ever marked failed and the sweep looked quiet
+ * -- but "correctly deferred, forever, on the same two rows" is still an
+ * unbounded backlog.
+ *
+ * REJECTED alternatives (see this commit's message for the full
+ * comparison against measured evidence): raising `MIN_STATEMENT_TIMEOUT_MS`
+ * or giving repair a larger bound than discovery both re-trap on the NEXT
+ * connection to cross whatever new ceiling is picked, since this query's
+ * cost is O(row count) with no upper bound. Reusing the maintained
+ * `retained_size_stream.record_count` counter was close but rejected: it
+ * carries no `last_updated`/`MAX(emitted_at)` column, and its row-presence
+ * semantics differ from this sparse GROUP BY in a way `buildRepairedRow`'s
+ * `known_zero` vs `unobserved` distinction depends on.
+ *
+ * The fix (this commit) adds `idx_pg_records_canonical_count` --
+ * `(connector_instance_id, deleted, stream) INCLUDE (emitted_at)` on
+ * Postgres, `(connector_instance_id, deleted, stream, emitted_at)` on
+ * SQLite -- covering this exact query shape. Verified directly at
+ * production-representative selectivity (one connection at ~4.4% of a
+ * 5.46M-row table, seeded in a throwaway scratch database, never
+ * production DDL): the identical query plans a `Bitmap Heap Scan` off this
+ * index at 83.7ms post-VACUUM, versus the 4.07s unindexed `Parallel Seq
+ * Scan` measured on live production data.
+ *
+ * This file proves, against REAL PostgreSQL:
+ *   - FAIL-BEFORE: with the new index dropped (reproducing the exact
+ *     pre-fix schema), genuine contention on `records` cancels a
+ *     connection's own repair read and leaves it durably dirty --
+ *     `repairCandidate`'s existing per-connection catch defers rather than
+ *     marking it failed (the 2026-08-11 fix stays correct), but the row
+ *     never converges.
+ *   - PASS-AFTER: with the index present (the migration's default state
+ *     after this fix), the query plan for the exact SQL shape
+ *     `repairCandidatePostgres` issues no longer requires a full table
+ *     scan, and the same contention window that broke repair before no
+ *     longer blocks it -- the connection's evidence is repaired and its
+ *     dirty flag clears.

+ * Root-cause fix, 2026-08-18: the fleet-wide canonical-count discovery read
+ * (`SELECT connector_instance_id, COUNT(*) FROM records WHERE deleted = FALSE
+ * GROUP BY connector_instance_id`, formerly in `readPostgresDiscoveryContext`
+ * / `readSqliteDiscoveryContext`, connector-summary-evidence-engine.ts) was
+ * removed. Measured on production (2026-08-18): 3.3-6.1 seconds, ~578,000
+ * buffers (~4.5 GB) read via `EXPLAIN (ANALYZE, BUFFERS)`, against a
+ * `records` table where only 11 of 5,460,609 rows are ever `deleted = true`
+ * -- essentially a full scan of the live table on every ~2-second sweep
+ * pass, always cancelled by the per-unit `statement_timeout` floor before it
+ * could complete.
+ *
+ * That query existed to catch one specific scenario: a direct writer that
+ * mutates `records` WITHOUT going through the normal version-allocating
+ * ingest/reset paths (so `version_counter` and the composite record-source
+ * checkpoint never change, even though the canonical row count did). This
+ * file proves that scenario is caught anyway, incrementally, with no
+ * fleet-wide scan of any kind:
+ *
+ *   - `connector_instances.source_revision` is advanced by the row-level
+ *     trigger `pdpp_source_revision_records`
+ *     (`ensurePostgresConnectorSummarySourceRevisionPrimitive`,
+ *     postgres-storage.ts; SQLite equivalent in db.ts), which fires on
+ *     EVERY INSERT/UPDATE/DELETE to `records` -- unconditionally, regardless
+ *     of whether the writer also touched `version_counter`.
+ *   - `classifyCandidate`'s `source_revision_mismatch` comparison
+ *     (connector-summary-evidence-engine.ts) already reads that single
+ *     already-fetched column and detects the drift.
+ *
+ * FAIL-BEFORE proves the failure mode the removed query was actually built
+ * to catch would go undetected if `source_revision` did not exist: bypassing
+ * the trigger machinery entirely reproduces exactly the blind spot the OLD
+ * canonical-count query was there to close. PASS-AFTER proves the current,
+ * always-on code path (writing through the real `records` table, trigger
+ * included, exactly as any real writer -- direct or ingest-mediated -- would)
+ * detects the same direct write and marks the row for repair, using only the
+ * already-batched `source_revision` comparison and no `records`-table scan.

+ * Production incident, 2026-08-18, DEPLOYED image `pdpp-core:drain10`
+ * (commit a5505bb59, immediately after it shipped): the exact
+ * `candidates_inspected: 0, skipped: 0, repaired: 0` symptom the deployed
+ * fix was meant to close PERSISTED, unchanged, after deploy. Postgres logs
+ * confirmed the OLD `records`-count query (the one a5505bb59 removed) was
+ * genuinely gone from the running container's queries after restart -- but a
+ * DIFFERENT query immediately took its place as the thing that times out:
+ *
+ *   SELECT connector_instance_id, MAX(event_seq) AS max_seq FROM spine_events
+ *     WHERE connector_instance_id = ANY($1::text[]) GROUP BY connector_instance_id
+ *
+ * (`readPostgresDiscoveryContext`'s `maxLifecycleSeqResult`,
+ * connector-summary-evidence-engine.ts, feeding `classifyCandidate`'s
+ * `lifecycle_checkpoint_lag` comparison -- a genuinely load-bearing signal
+ * added 2026-07-29, unlike the redundant `records` count a5505bb59 deleted).
+ *
+ * Root cause: `idx_pg_spine_events_terminal_instance_seq` only covers the
+ * four TERMINAL event types (`WHERE event_type IN ('run.completed', ...)`).
+ * The lifecycle query groups by `connector_instance_id` over EVERY event
+ * type, so it fell through to a full parallel seq scan -- measured directly
+ * against production, 2026-08-18: 1.5-1.9s / ~117k buffers (~940 MB) via
+ * `EXPLAIN (ANALYZE, BUFFERS)` on 1.4M spine_events rows, with the scoped
+ * `= ANY(...)` form no faster (the planner cannot prune an unindexed
+ * column). That was slow enough, under real production contention, to blow
+ * discovery's remaining per-pass admission allowance every ~60s sweep pass.
+ *
+ * Because `readPostgresDiscoveryContext` issues every one of its seven
+ * sequential queries through `postgresDiscoveryQuery` with NO per-query
+ * try/catch (unlike `repairCandidate`, which the 2026-08-11
+ * `reasonCodeForRepairFailure`/`logRepairFailure` machinery isolates
+ * per-connection), a `PostgresStatementTimeoutError` cancelling THIS query
+ * propagates out of `discoverCandidates` exactly like the `records` count
+ * used to -- `observeConnectorSummaryEvidence`'s existing 92c9fc83e catch
+ * converts that into a clean `candidates_inspected: 0, incomplete: true`
+ * pass (not a crash, not corrupted evidence), but it also means NOTHING in
+ * the batch was ever classified: a durably-`dirty` row (which
+ * `classifyCandidate` would resolve on its very FIRST comparison, long
+ * before it would ever reach the lifecycle-seq comparison this cancelled
+ * query feeds) is never even attempted. Same "repaired: 0, skipped: 0
+ * forever" shape as the incident a5505bb59 fixed, one query later in the
+ * same sequential list.
+ *
+ * The fix (this commit) adds a general, unfiltered
+ * `(connector_instance_id, event_seq)` index -- `idx_pg_spine_events_
+ * instance_seq` in postgres-storage.ts, `idx_spine_events_instance_seq` in
+ * db.ts -- covering every event type, not just the four terminal ones. This
+ * is the SAME fix already proven for the terminal-scoped case
+ * (`idx_pg_spine_events_terminal_instance_seq`); unlike the `records` count
+ * a5505bb59 deleted, the lifecycle-seq query cannot simply be removed -- it
+ * is the only durable backstop for `run.started`/`run.progress_reported`
+ * events beyond terminal outcomes (see `classifyCandidate`'s
+ * `lifecycle_checkpoint_lag` doc, 2026-07-29 terminal-gate revision).
+ *
+ * SECOND, DETERMINISTIC call site (found chasing a fresh log line that
+ * appeared post-restart and looked, at first, like a DIFFERENT bug): every
+ * ~60s tick, `connector-maintenance-sweep.ts` alternates which of two
+ * tranches (`walk` / dirty-priority `acceleration`) runs first
+ * (`runBoundedSummaryEvidenceSweep`, 2026-08-12 starvation fix). On a
+ * `walkFirst` tick, `runWalkTranche` is awaited BEFORE
+ * `runAccelerationTranche` -- and if the walk's own `onPageConverged`
+ * callback throws anything other than the one allow-listed
+ * `TERMINAL_PROJECTION_PUBLICATION_RACE` (`isExpectedProjectionRace`,
+ * connector-summary-read-model.ts), that throw propagates out of the WHOLE
+ * `runBoundedSummaryEvidenceSweep` call -- `runAccelerationTranche` (the
+ * ONLY path that reads the dirty-priority backlog) never runs AT ALL that
+ * tick. Production, 2026-08-18: connection `cin_992b0c94cebeb3066ba42a6e`
+ * (Signal, 6,448 records, created 19:22:40, ZERO `spine_events` rows) had no
+ * `connector_summary_evidence` row at all, so every walk page reaching it
+ * threw `"Cannot publish connector list summary without canonical evidence"`
+ * (`ref-control.ts:7012`) -- NOT the allow-listed race, so it escaped
+ * uncaught, killing the walk tranche (and, on `walkFirst` ticks, the
+ * acceleration tranche with it) every time its page came up. That
+ * connection never got its OWN evidence row created for the SAME reason:
+ * `repairCandidatePostgres`'s per-connection lifecycle read --
+ * `SELECT MAX(event_seq) FROM spine_events WHERE connector_instance_id =
+ * $1` (connector-summary-evidence-engine.ts, `lifecycleHighWaterResult`,
+ * NO event_type filter, NO GROUP BY) -- hits the exact same unindexed
+ * column. Proven directly against production (READ-ONLY): even with ZERO
+ * matching rows, `EXPLAIN (ANALYZE, BUFFERS)` against this query for
+ * `cin_992b0c94cebeb3066ba42a6e` still timed out at a 10-SECOND budget --
+ * an unindexed predicate cannot be pruned by absence of matches, so a
+ * connection with NO spine history pays the SAME full-scan cost as one
+ * with millions. The general index this file's other tests prove covers
+ * `readPostgresDiscoveryContext`'s batched, GROUP-BY form also covers this
+ * single-row, non-grouped form -- confirmed directly: `EXPLAIN` for the
+ * identical zero-match shape plans an `Index Only Scan`
+ * (`idx_pg_spine_events_instance_seq`) once the index exists, not a scan of
+ * the whole table. One index fix closes both the batched-discovery
+ * starvation AND the per-connection repair failure that was crashing the
+ * walk tranche.
+ *
+ * This file proves, against REAL PostgreSQL:
+ *   - FAIL-BEFORE: with the new index dropped (reproducing the exact
+ *     pre-fix schema), genuine contention on `spine_events` cancels the
+ *     lifecycle-seq query and aborts discovery for the WHOLE requested
+ *     batch -- an unambiguously dirty row is never even attempted.
+ *   - PASS-AFTER: with the index present (the migration's default state
+ *     after this fix), the query plan for the exact SQL shape
+ *     `readPostgresDiscoveryContext` issues no longer requires a full
+ *     table scan (`EXPLAIN` shows an Index Scan/Only Scan, not a Seq
+ *     Scan), and the same contention window that broke discovery before no
+ *     longer blocks it -- the dirty row is discovered, classified, and
+ *     attempted.
+ *   - PER-CONNECTION REPAIR, zero-match case: a connection with NO
+ *     `spine_events` rows at all (the Signal shape above) can still create
+ *     its evidence row via `repairCandidate` within a tight deadline --
+ *     proving the fix closes the repair-side failure, not just the
+ *     batched-discovery side.

+ * Production regression, 2026-08-18: deploying commit c7da5ea94 ("give sweep
+ * queries a real per-unit bound") flipped 25 of 29 `connector_summary_
+ * evidence` rows from `record_snapshot_state: current` to `failed` /
+ * `record_snapshot_reason_code: summary_discovery_failed` within minutes,
+ * with the maintenance sweep reporting `candidates_inspected: 0, repaired: 0,
+ * skipped: 0, incomplete: false` while `eligibleBacklog` sat flat — and NO
+ * `statement_timeout`/57014/`PostgresStatementTimeoutError` anywhere in the
+ * container logs. Rolling back to the prior image restored all 29 rows to
+ * `current`.
+ *
+ * Root cause, traced to file:line:
+ *   1. `MIN_STATEMENT_TIMEOUT_MS` (connector-summary-evidence-engine.ts) was
+ *      50ms, and the maintenance sweep runs the terminal-facts fold BEFORE
+ *      discovery/repair (`runBoundedObservationPhases`, connector-summary-
+ *      read-model.ts) inside one shared 2000ms round budget — so discovery
+ *      routinely started with little or no admission allowance left,
+ *      collapsing `remainingStatementBudgetMs` to the 50ms floor on nearly
+ *      every pass. The doc comment's claim that "every query this floor
+ *      applies to is index-bounded" was false for discovery's own
+ *      `COUNT(*) GROUP BY` over `records` (no index covers `deleted`) — the
+ *      exact query this whole mechanism exists to bound.
+ *   2. `observeConnectorSummaryEvidence`'s outer catch (connector-summary-
+ *      read-model.ts) caught EVERY thrown error the same way, including
+ *      `PostgresStatementTimeoutError`, and converted it into
+ *      `markAllConnectorSummaryEvidenceDiscoveryFailed` — durably degrading
+ *      `record_snapshot_state`/`manifest_declaration_state` to `failed` for
+ *      every row in scope — with no `console.error`/`console.warn` call
+ *      anywhere on that path. A real, correctly-thrown, correctly-typed
+ *      SQLSTATE-57014 error was silently converted to an opaque sanitized
+ *      string in a DB column and never reached stdout/stderr.
+ *
+ * This file proves, against REAL PostgreSQL (a mock cannot prove Postgres
+ * itself cancels the statement):
+ *   - FAIL-BEFORE: at the pre-fix 50ms floor, a realistically-slow discovery
+ *     read (simulated with genuine `ACCESS EXCLUSIVE` lock contention on
+ *     `connector_instances`, not a mock) is cancelled, and the resulting
+ *     `PostgresStatementTimeoutError` — reaching the ACTUAL production catch
+ *     path — is silently swallowed into a `failed` evidence row with no
+ *     console output.
+ *   - PASS-AFTER (current code): the same contention is genuinely survived
+ *     by the raised floor (healthy discovery is not spuriously cancelled),
+ *     AND, independently, a statement that IS cancelled is surfaced as a
+ *     distinguishable, loud, logged error and does NOT mark evidence
+ *     `failed` — existing evidence is left untouched and the round reports
+ *     `incomplete: true` so it is honestly retried.

+ * Reproduction (2026-08-18): two production rows (a finished Google Maps
+ * Timeline import and a finished WhatsApp archive import, both
+ * `source_kind='manual'`, zero `run.*`/terminal spine events ever) are
+ * durably stuck at `terminal_facts_state: 'stale'` /
+ * `terminal_facts_reason_code: 'terminal_facts_historical'` in production,
+ * even though `connector-summary-historical-terminal-facts-health.test.ts`'s
+ * own doc comment says a genuinely never-folded zero-history row "converges
+ * to `terminal_facts_state: 'current'`... and never reaches
+ * `terminal_facts_historical` at all."
+ *
+ * That existing test only exercises
+ * `foldConnectorSummaryStreamFacts([INSTANCE_ID])` — a SINGLETON scope. The
+ * real periodic maintenance sweep never calls the fold that way: it walks
+ * PAGES of many connection ids at once
+ * (`observeConnectorSummaryEvidence(pageIds, { deadline, ... })`, default
+ * page size 25 — see `runBoundedSummaryEvidenceSweep` in
+ * connector-summary-read-model.ts). When a zero-history row shares a page
+ * with ANY other connection that has real terminal history (true for almost
+ * any production page), `readMaxTerminalEventSeq(pageIds)` returns a
+ * non-null, page-wide high-water mark, so the `maxSeq === null` bootstrap
+ * branch (`stampZeroCheckpointForBootstrap`) never fires for that page at
+ * all.
+ *
+ * The mechanism this file proves: `seedFoldState` seeds
+ * `generationCurrentSeedByInstance` for each row from its OWN INCOMING
+ * `terminal_facts_reason_code` — a row already stamped
+ * `terminal_facts_historical` seeds `false` ("not current"). A zero-history
+ * row's scoped terminal-event read always returns an empty batch (it has no
+ * terminal events, full stop), so `foldTerminalEventFacts` — the ONLY thing
+ * that can flip `generationCurrentByInstance` back to `true` — is never
+ * invoked for it. The seeded `false` survives untouched to the write phase,
+ * so `terminalFactsCurrent = ownReplayConverged && sourceGenerationCurrent`
+ * evaluates to `false` even though `ownReplayConverged` is `true` (its own
+ * cursor genuinely reached its own high-water). The row re-writes itself
+ * back to `terminal_facts_historical` every single page-scoped pass,
+ * forever — a self-perpetuating state with no path back to `current` once
+ * ANYTHING (a stale pre-fairness-fix fold pass, or this same bug) first
+ * stamps it `historical`.

  * `runBoundedSummaryEvidenceSweep`'s own ordering comment for the full
  * argument.
  *
- * This file proves, with a REAL fold-heavy backlog (not a simulated clock
- * jump — the whole point is that cooperative overshoot is real, not a
- * modeling artifact):
+ * HOW THE STARVATION PRECONDITION IS ESTABLISHED (rewritten 2026-08-21).
+ * Earlier revisions of this file tried to make page 1 saturate the round by
+ * seeding a very large real backlog and racing it against a small real
+ * `ROUND_MS`. That approach is structurally incapable of working, and its
+ * repeated recalibration (100k -> 400k) was chasing a number that cannot be
+ * made to hold:
+ *
+ *   The fold is capped by EVENT COUNT, not by backlog size.
+ *   `drainTerminalFactEvents` returns as soon as `eventsProcessed >=
+ *   maxEvents` (`BOUNDED_FOLD_MAX_EVENTS`, 500 by default), regardless of
+ *   how many events remain unfolded. A 100k backlog and a 400k backlog
+ *   therefore perform the SAME 500-event fold per round — measured: ~20ms
+ *   at 100k and ~50-90ms at 400k, where the entire difference is index-seek
+ *   depth, not folding work. Raising the backlog does not raise the round's
+ *   cost to any bound; it only nudges a wall-clock measurement around the
+ *   `ROUND_MS` threshold until the machine's speed decides the verdict.
+ *   That is precisely a timing race, and it is what made this test ambient-
+ *   red: it began passing/failing on fold cost the code never promised.
+ *
+ * The property under test was never "a big backlog is slow." It is: WHEN the
+ * walk consumes the round, acceleration gets no turn. "The walk consumes the
+ * round" is the PRECONDITION, not the thing being measured — so it is
+ * established deterministically, via the same injected sweep clock the
+ * sibling deadline tests already use (`connector-summary-sweep-no-late-
+ * start.test.ts`, `connector-summary-dirty-priority-attempted-fairness.
+ * test.ts`): the walk's own page-discovery seam advances the clock past the
+ * round's deadline, modelling a genuinely fold-heavy page exactly.
+ *
+ * This is not a weaker test — it is a strictly stronger one. Cooperative
+ * overshoot is real, and modelling it with a controlled clock asserts the
+ * ORDERING invariant on every host instead of only on hosts slow enough for
+ * a 500-event fold to cross 50ms. A modest real backlog is still seeded, so
+ * page 1 genuinely reports `incomplete` from real unfolded history rather
+ * than from the clock alone.
+ *
+ * This file proves:
  *   1. FAIL-BEFORE: with `firstTranche` fixed at `"walk"` every round (the
  *      pre-fix call shape), a fresh dirty row on a later page starves across
- *      several rounds while page 1's backlog keeps the walk saturated.
+ *      several rounds while page 1's fold keeps the walk saturated.
  *   2. FIX / discriminator (1): alternating `firstTranche` converges the
  *      SAME fresh dirty row within a small, bounded number of rounds, even
  *      though page 1 remains genuinely stuck throughout.

+ * That is precisely how the production defect survived a test suite that
+ * already covered boot-orphan reconciliation. `resolveControllerId` fell back
+ * to `os.hostname()`, which under Docker is the container ID and is fresh on
+ * every `docker run`, so the reconciler's ownership filter matched nothing
+ * after any container replacement. 121 production runs from 106 distinct
+ * controller ids were left permanently non-terminal between 2026-05 and
+ * 2026-07.
+ *
+ * The load-bearing move here is therefore to simulate a NEW CONTAINER — a

+ * Cursor-band contiguity oracle.
+ *
+ * The anchor case is the REAL live-instance defect: the Gmail `messages`
+ * cursor held `backfill.target_uid: 323723` and `all_mail.forward_uidnext:
+ * 324021`, orphaning 297 UIDs (two days of mail) that neither the historical
+ * walk nor the forward walk would ever fetch — while every coverage signal
+ * still read `covered == considered`, because the connector genuinely did
+ * process everything it fetched.
+ *
+ * The tests below pin four separable behaviors, so a mutation to any one of
+ * them reddens on its own:
+ *   1. the violation fires, with the exact band size, on the real defect state;
+ *   2. the repaired live state (`324020`/`324021`) is contiguous — the
+ *      boundary case, which a naive `>` instead of `>=` would fail;
+ *   3. silence (never a violation) for undeclared streams, unrecognized
+ *      declared shapes, half-written cursors, and mismatched UIDVALIDITY
+ *      epochs;
+ *   4. the variant table excludes every non-two-pointer shape in the live
+ *      fleet, and gmail's manifest still declares the shape that opts its
+ *      `messages` stream into the check at all.

+ * A server restart must not push the next run out by a full interval.
+ *
+ *   BUG: `newestHistoryEpochMs` (dispatch-governor.ts) walked run history and
+ *   took the newest `completedAt` with NO status or reason filter. When a
+ *   restart kills an in-flight run, reconciliation writes a terminal row whose
+ *   `completedAt` is "now" — so that row became the schedule anchor and the
+ *   connection waited a fresh full interval from the moment of the restart.
+ *
+ *   A source killed 11 hours into a 12-hour cycle therefore waited another 12
+ *   hours. The restart did not merely lose the in-flight run; it then DELAYED
+ *   the recovery run by an entire interval. That is why sources stayed stale
+ *   long after a deploy.
+ *
+ *   Production scale (`run_history`): 45 restart-ended runs since 2026-08-15
+ *   (28 `controller_terminated_before_run_finished` + 17 `controller_restarted`).
+ *
+ * FIX: skip restart-ended runs when computing that fallback anchor. They
+ * observed nothing — the process died holding the run — so they are not
+ * evidence that "we just ran".
+ *
+ * WHY THIS KEYS ON THE TERMINAL REASON, NOT THE STATUS. The two restart
+ * reasons are stored with DIFFERENT statuses, verified against production:
+ * `controller_terminated_before_run_finished` is `status='abandoned'` (28
+ * rows) while `controller_restarted` is `status='failed'` (17 rows). A
+ * status-only filter would silently miss the second — and would also be
+ * dangerously broad, since ordinary failures MUST keep anchoring so back-off
+ * works. The third test below is the guard for exactly that.

+ * Integration suite for the owner-agent connection-resume control routes
+ * (bearer: `server/routes/owner-connection-resume.ts`):
+ *
+ *   POST /v1/owner/connections/:connectionId/resume  (bearer, on RS)
+ *   POST /v1/owner/connectors/:connectorId/resume    (bearer, on RS)
+ *
+ * Resume is the `paused`-status sibling of reactivate (`owner-connection-reactivate.ts`,
+ * which flips `revoked` -> `active`). It exists because before this route, no
+ * path in the reference implementation ever transitioned a connector_instance
+ * from `paused` back to `active` — a connection paused by an out-of-band
+ * operation (e.g. a recovered historical-archive row, restored with
+ * `status: 'paused'` specifically because activating it with no surviving
+ * credential would be unsafe) had no way back to `active` even after the
+ * owner re-sealed a working credential via the static-secret credential-
+ * capture route (which now admits a `paused` target — see
+ * static-secret-credential-probe-route.test.ts).
+ *
+ * Covers:
+ *   - a paused connection is flipped to `active`, already-collected records
+ *     are preserved, and a resume audit event is emitted;
+ *   - resume on a non-paused (active) connection returns connector_instance_not_paused (409);
+ *   - resume on a foreign/unknown connection_id returns connector_instance_not_found (404);
+ *   - a cross-owner resume is rejected (foreign id -> 404);
+ *   - the connector-only bearer route auto-selects a single paused connection;
+ *   - client grant tokens (403) and missing bearers (401) cannot resume;
+ *   - a repeat resume on an already-active connection returns 409.

+ * Production incident, 2026-08-21: the owner's source-detail page took 44.5s
+ * while a Google Maps re-ingest of 299,248 records ran concurrently.
+ *
+ * Two independent causes. The dominant one -- a missing keyset index on
+ * `records`, which made BOTH the page's query and the backfill's own
+ * coverage scan multi-second -- is fixed separately
+ * (`idx_pg_records_instance_stream_id`). This file covers the second: the RI
+ * runs the HTTP server, the scheduler and the connector/embedding runtime in
+ * ONE Node process sharing ONE node-postgres Pool that never set `max`, so
+ * the library default of 10 connections was the whole budget for interactive
+ * request handlers AND background bulk work together.
+ *
+ * That is a QUEUEING failure, not a duration failure: even with every bulk
+ * statement fast, enough concurrent bulk work can leave an interactive
+ * handler waiting on `pool.connect()` for a connection that does not exist.
+ * Chunking cannot fix it (the chunks are what exhaust the pool) and neither
+ * can the index (it makes each statement cheap, not the supply larger).
+ *
+ * Worth stating plainly, because the incident write-up assumed otherwise:
+ * the bulk path was ALREADY chunked before this change. The semantic rebuild
+ * pages `records` 500 rows at a time and issues each page's read and write as
+ * its own autocommit statement, holding no transaction across pages. So the
+ * remedy here is not "introduce chunking" -- it is to give that already-
+ * chunked work a lane of its own and a hard ceiling.
+ *
+ * This file proves, against REAL PostgreSQL:
+ *   - Bulk work draws from a DIFFERENT pool than interactive work, so
+ *     saturating the bulk lane leaves interactive capacity intact.
+ *   - The bulk lane is bounded: a statement that exceeds the bulk
+ *     `statement_timeout` is cancelled by Postgres and surfaces as
+ *     `PostgresStatementTimeoutError`, not as an unbounded hang.
+ *   - That bound is `SET LOCAL` and therefore does NOT leak onto the next
+ *     caller to reuse the same physical connection.

+ * `postgresQueryBounded` — the per-unit HARD bound design review P1-2
+ * requires ("For PostgreSQL, set a transaction-local `statement_timeout`
+ * ... based on the unit's remaining allowance"), proven against a REAL
+ * Postgres server, not a mock: a mock can only prove the SQL text was sent,
+ * never that Postgres itself actually enforces and cancels the statement.
+ *
+ * Proves:
+ *   1. A statement that runs LONGER than its `timeoutMs` is genuinely
+ *      cancelled by Postgres (SQLSTATE 57014) and surfaces as
+ *      `PostgresStatementTimeoutError`, not left to run to completion.
+ *   2. A statement that runs WELL WITHIN its `timeoutMs` completes normally
+ *      and returns real rows — the bound does not fire on fast, ordinary
+ *      queries (the `MIN_STATEMENT_TIMEOUT_MS` floor in
+ *      connector-summary-evidence-engine.ts exists precisely so this stays
+ *      true even with very little remaining budget).
+ *   3. The timeout is TRANSACTION-LOCAL (`SET LOCAL`): after a bounded call
+ *      times out and its connection is released back to the pool, the very
+ *      next query on that SAME pool (which may reuse the same physical
+ *      connection) is NOT affected by the prior timeout — proving the
+ *      reviewer's "cannot leak to other users of a pooled connection"
+ *      requirement, not merely asserting the SQL text contains `LOCAL`.
+ *
+ * Gated on `PDPP_TEST_POSTGRES_URL` pointing at the dedicated, loopback-only
+ * test listener (see `test/helpers/dedicated-postgres-test-url.ts`); skips
+ * (never fails) when unset, matching every other Postgres-gated test in
+ * this suite. This is the one part of the P1-2 fix that CANNOT be proven on
+ * SQLite (better-sqlite3 has no interrupt/progress-handler hook — see the
+ * P1-2 report), so this file is the only place the per-unit hard bound is

+ * Production incident, 2026-08-21: the owner's source-detail page took 44.5s
+ * while a Google Maps re-ingest ran concurrently.
+ *
+ * The keyset-pagination shape both the source-detail page and the semantic
+ * backfill's coverage scan issue --
+ *
+ *   SELECT id, record_key, ... FROM records
+ *    WHERE connector_instance_id = $1 AND stream = $2 AND deleted = FALSE
+ *      AND id > $3
+ *    ORDER BY id ASC LIMIT $4
+ *
+ * -- had NO index able to serve it. All seven of `records`' pre-existing
+ * indexes lead with `connector_instance_id`, but none carries `id` as the
+ * column immediately following the equality predicates, so none can satisfy
+ * the ORDER BY. The closest, `idx_pg_records_stream_cursor`, is
+ * `(connector_instance_id, stream, deleted, cursor_value, primary_key_text)`
+ * -- its fourth column is `cursor_value`, not `id`.
+ *
+ * So the planner fell back to `records_pkey`: already `id`-ordered (free
+ * sort), then filtered every non-matching row away one at a time. Measured
+ * READ-ONLY against production for `cin_12407c1afb78d56848fe0b20`/`messages`
+ * (140,689 live rows in a 5.61M-row table): 27.4 SECONDS for 50 rows,
+ * `Rows Removed by Filter: 3,031,420`.
+ *
+ * The same shape is ALSO the bulk path. `postgresSemanticRecordsPage`
+ * (postgres-search.ts) issues it with `LIMIT 500`, and live
+ * `pg_stat_activity` sampling during a real re-ingest caught successive
+ * pages at 1.2s, 1.6s, 1.9s, 7.0s, 12.2s, 17.2s, 22.3s and 27.4s. The bulk
+ * job was not merely competing for resources with the page -- it was hitting
+ * the identical missing index from a second call site.
+ *
+ * This file proves, against REAL PostgreSQL:
+ *   - FAIL-BEFORE: with `idx_pg_records_instance_stream_id` dropped
+ *     (reproducing the exact pre-fix schema), the planner picks
+ *     `records_pkey` and reports a large non-zero `Rows Removed by Filter`
+ *     -- the production defect's signature.
+ *   - PASS-AFTER: with the index present (the migration's default state),
+ *     the same query plans an `Index Scan using
+ *     idx_pg_records_instance_stream_id`, absorbs all four predicates into
+ *     `Index Cond`, and removes ZERO rows by filter.
+ *
+ * UNLIKE this repo's canonical-count index test (which deliberately avoids
+ * plan-shape assertions), asserting the plan is the RIGHT proof here,
+ * because the defect IS a plan defect: the wrong plan is not a cost-model
+ * tie-break, it is the planner having no candidate index that can produce
+ * `id` order under these predicates. That property holds at any row count.
+ * The fixture below still seeds enough interleaved rows that a `records_pkey`
+ * walk must genuinely discard thousands of rows, so the FAIL-BEFORE
+ * signature is the production one and not an artifact of an empty table.

+ * route (`server/routes/ref-connection-resume.ts`):
+ *
+ *   POST /_ref/connections/:connectorInstanceId/resume
+ *
+ * Like the bearer sibling (`owner-connection-resume.ts`), this route resumes
+ * ANY paused row the owner owns, regardless of `source_binding.kind`; it
+ * differs only in auth (session cookie) and in targeting exactly one
+ * connectorInstanceId. An earlier revision additionally required
+ * `source_binding.kind === 'historical_archive'`, because the recovered-archive
+ * reconnect was the only shipped use of owner-session resume. Now that pause
+ * is a first-class owner action, that guard would strand every deliberately
+ * paused source, so it applies only to the IMPLICIT auto-resume hooks.
+ *
+ * Both routes share the SAME status-flip primitive (`applyResume`, exported
+ * from `owner-connection-resume.ts`) — this suite proves the session route's
+ * OWN behavior (auth, exact-id targeting, status gating), not a duplicate of
+ * the bearer suite's status-flip assertions.

+ * Behavior to preserve exactly (D14) -- this is a refactor of truth-keeping,
+ * so these are gates, not aspirations:
+ *
+ *  1. Idempotency keys on `caused_by_event_id` via the

+ *     SQLITE_CONSTRAINT_UNIQUE. A blanket catch would swallow real defects.
+ *  2. The newest-epoch exclusion is load-bearing. Without it, adjudication
+ *     declares LIVE work abandoned and frees its resource for a competing
+ *     run. The production dry run reported 123 before the exclusion and 121
+ *     after; the two extras were runs a live container had started ninety
+ *     seconds earlier.
+ *  3. Eligibility is decided by epoch comparison, never by an age threshold.
+ *  4. An interruption while awaiting owner interaction carries its own
+ *     distinct reason. Collapsing it into the generic reason changes
+ *     observable output -- an owner who was sent an OTP that then became
+ *     useless is told why.
+ *  5. `records_emitted` is never revised. Records durably ingested before the
+ *     interruption stay committed.
+ *  6. Provenance stays distinguishable: the boot reconciler and the repair

+// Oracle for the connector runtime's retry against a NETWORK-LEVEL fetch
+// failure — distinct from `runtime-ingest-retryable-503.test.ts`, which covers
+// a response the RS chose to send (a retryable status code).
+//
+// The defect this covers: live incident on the Google Maps Timeline import
+// (cin_50f5bf4b7ecbc7acd6f4c254, run_1787334764061). 269,000 of 269,500
+// attempted records were durably accepted, then the runtime's last in-flight
+// ingest batch (500 records — the default PDPP_RUNTIME_BATCH_SIZE) hit a raw
+// `fetch()` throw (`TypeError: fetch failed`, no HTTP response at all) that
+// `postIngestBatchWithRetry` did not catch: it only classifies a STATUS CODE
+// the server returned (`isRetryableIngestStatus`), so a connection-level
+// failure skipped the retry loop entirely and killed the whole run with
+// `terminal_reason: runtime_error`. Because the crash happened mid-ingest,
+// before the connector reached its STATE-emitting phase, the checkpoint read
+// `not_staged` with no denominator despite 269,000 records already being
+// safely stored — reported to the owner as "coverage unknown" for data that
+// was, in fact, present.
+//
+// A second, independently-reachable instance of the identical gap lives in
+// `commitState`'s STATE PUT (the terminal checkpoint commit), which had no
+// retry wrapper at all before this fix. These tests cover both call sites
+// using the same scripted-stub-RS harness as the 503 oracle: the stub
+// destroys the raw TCP socket before responding (a real ECONNRESET, not a
+// mocked error), forcing `fetch()` itself to throw exactly as it did in the
+// live incident.

+// The defect this covers: the RS answers a SYSTEMIC ingest failure with 503
+// `ingest_batch_storage_error` — a status its own error-status table documents
+// as "safe to retry the identical batch" — and the runtime's `flushBatch` used
+// to issue a bare `fetch` that threw on any non-2xx. The 503 killed the run and
+// discarded every buffered record. In production that dropped 56,440 buffered
+// records across 129 runs.
+//
+// These tests drive the REAL `runConnector` against a scripted stub RS, so the
+// retry decision under test is the runtime's own `postIngestBatchWithRetry`,
+// not a mock of it. The stub is deliberately minimal: it answers only the three
+// endpoints a run touches (state GET/PUT and the ingest POST) and scripts the
+// ingest status sequence per test.
+//
+// No test here sleeps for real. `ingestRetrySleep` and `ingestRetryRandom` are
+// injected, so the retry SEQUENCE (attempt count, per-attempt delay, honored
+// `Retry-After`, bounded exhaustion) is asserted deterministically and the whole
+// file runs in milliseconds. A test that genuinely slept would be both slow and

+ * Regression for production `run_1787101857760` (2026-08-18, the owner's
+ * first-ever Venmo run): `connector_error_json.message` recorded
+ * `"venmo_session_failed: [REDACTED]: Failed to fetch"`. The full, unredacted
+ * message (`spine_events.data_json.run.failed.known_gaps[].message`, which
+ * bypasses `boundConnectorErrorMessage`) proved the eaten token was
+ * `venmo_probe_transport_error` — a 27-char, PII-free categorical fault-class
+ * name, not a secret. `stderr-redact.ts`'s `LONG_OPAQUE_RE` treats any
+ * >=24-char alnum run as an unlabelled-API-key risk with no notion that a
+ * declared reason code is not that.
+ *
+ * `runtime/stderr-redact.ts` already had a `declaredReasonTokens` allowlist
+ * mechanism (added the same day for an identical HEB incident), but it was
+ * wired only into `run-logger.ts` (internal scheduler/executor logging) —
+ * never into `boundConnectorErrorMessage`, the function that actually
+ * redacts `connector_error_json.message` before it reaches a durable spine
+ * event. This suite proves that gap is closed.
+ *
+ * WHAT THIS FILE TESTS, AND WHAT IT DOES NOT
+ * ------------------------------------------
+ * These are RI-side tests, so they exercise the RI's side of the contract:
+ * given a manifest that declares tokens, does redaction honor them, and does
+ * a manifest that declares none stay byte-identical to prior behavior. The
+ * manifests below are SYNTHETIC — the RI must work for any connector, so
+ * pinning these tests to a real connector's file would re-import exactly the
+ * connector knowledge this seam exists to remove.
+ *
+ * The DRIFT check — that Venmo's real manifest array still equals the
+ * `VENMO_DECLARED_REASON_TOKENS` constant its throw sites actually use —
+ * lives connector-side, next to the source of truth, in
+ * `packages/polyfill-connectors/src/auto-login/venmo-declared-reason-tokens-manifest.test.ts`.

 SKIP_RESULT is a message emitted while in the `collecting` state. It does not cause a state transition.

 A missing or mismatched terminal code, a missing or untargeted skip, an out-of-scope stream, a protocol violation, an invalid terminal count or exit code, a process exit without valid DONE, or cancellation MUST preserve the default fail-closed rule and persist no staged STATE.

+**Restart abandonment.** A process exit without valid DONE caused by the CONTROLLER being replaced or restarted -- not by the connector failing -- MAY persist a staged STATE checkpoint for a checkpoint stream that satisfies ALL of the following, and MUST persist none otherwise:
+
+1. The run's terminal reason is a controller-lifecycle reason (the controller died; the connector did not report failure).
+2. The checkpoint stream is not a declared detail-coverage parent in the connector's manifest, so it can never face a DONE-time coverage verdict. Eligibility is derived from the MANIFEST alone; a connector MUST NOT be able to declare its own eligibility.
+3. The stream has no pending detail gap and no unproven coverage for the completed prefix.
+
+This exception exists because a walk longer than the interval between controller restarts can otherwise never converge -- it is a completeness failure, not a slowness one. It does not weaken the invariant that a cursor MUST NOT advance past records whose coverage was not proven: a stream that could face such a verdict is excluded by condition 2, and unproven coverage is excluded by condition 3. The run's status remains failed/abandoned and every withheld stream stays eligible for retry.
+
 `error` MAY carry `code` and/or `recovery_hint`, in addition to the required `message` and `retryable`:
 
 - `code` is a stable, connector-defined **cause identity** (e.g. distinguishing one failure mode from another). It is a bounded `snake_case` identifier (a lowercase letter followed by up to 63 lowercase letters, digits, or underscores), an identity rather than an instruction — the runtime MUST NOT treat `code` as, or derive, an owner-facing recovery action from it.
