From b8ee2d5b4e192de252d133b9c6e6bda3326737d6 Mon Sep 17 00:00:00 2001 From: Tim Nunamaker Date: Mon, 17 Aug 2026 06:59:53 -0500 Subject: [PATCH 001/264] fix(slack): declare message coverage once per run, not once per scoped archive Slack emitted a DETAIL_COVERAGE record for (state_stream=messages, stream=messages) inside runRequestedStreams, which the message-family fold calls once per scoped archive. The runtime rejects a repeated (state_stream, stream) pair, so any workspace with more than one scoped archive failed the run outright. Production has three, and the connection has eight failed runs and no successes at all. Reproduced on live data while diagnosing: a manually triggered run collected 2,030 records and then died on exactly this error. mergeScopedMessageArchivePasses already sums `considered` across the base archive and every scoped archive, so the correct denominator was being computed and then discarded. The emission is now hoisted out of the loop into declareMergedMessageCoverage, called once per run with that merged total; reactions and message_attachments ride the same call, since they declared the same parent boundary and had the identical defect. Single-archive runs emit exactly one record with the value they emitted before. Only the multi-archive case changes. The accompanying test builds two disjoint single-channel scoped archives and fails against unmodified source with the duplicate error.

That is the normal result of a device running a build older than the server, and it made a single stale store name discard an otherwise complete proof. Measured on production: connection cin_ece4bfe5096b8bf67a1468c2 ("peregrine Codex") has 1,293,596 collected records, summary evidence fresh with every component current, a current heartbeat and a fully drained outbox, and displayed "Not measured". The only drift was one legacy `logs` store. Nothing was missing; every declared store was reported. The asymmetry is the change. A collector reporting a store this build no longer declares scanned MORE than was asked of it, which cannot weaken a completeness claim -- and unexpected entries were already excluded from the accounted rows, so they could never corrupt the proof either. Their only effect was to fail the gate. A MISSING store is the opposite: the collector did not account for something the server requires, so the snapshot genuinely is not committed. Missing, duplicate and malformed remain fatal. unexpectedStores stays in the result, so the drift remains observable; it is now informational rather than disqualifying. Prior art agrees on the shape: restic exits 3 for "some source files could not be read" while still creating a usable snapshot, borg separates warning from error, and rclone check reports missing-on-dst and differ as distinct named categories. None discards a result because it is imperfect in one direction.

The server exits, the supervisor restarts it, the next attempt times out on the same unnamed holder, and the loop continues indefinitely. Observed cost today: a wedged DELETE FROM records, orphaned from a killed process, held a conflicting lock on connector_instances. Every boot queued behind it and the reference listener never bound its port, so the app served errors while the database was healthy and fully intact. Rolling the image back did not help -- and could not, because the blocker lived in Postgres rather than in the container, and survived every container restart. Diagnosing it by hand cost roughly 20 minutes of downtime. Postgres could have answered in one query. The timeout error now appends the holding sessions: pid, state, wait event, and how long the statement has run. Best-effort and deliberately non-fatal -- this runs on a path that is already failing, so a diagnostic that throws would replace a useful error with a worse one. It reports no query text, which can carry record values, and caps at five rows. Both branches exercised against live Postgres: with no advisory holder it reports that the contention is likely a table-level lock elsewhere; with a holder it renders "Held by: pid 2186703 (active, waiting on Timeout, 4s)".

With a 2s budget it read zero qualifying events, wrote nothing, reported incomplete, and repeated -- leaving all 25 rows terminal_facts_historical indefinitely.

Building from fd8f617b1 therefore shipped a binary OLDER than the data it reads: 26 of 28 evidence rows carry stream_facts_fold_version=5, and the version guard correctly failed closed with fold_logic_version_incompatible_future rather than corrupting them. The visible result was ProjectionReliable=false on nearly every source and a fleet of grey pills, which reads identically to having no evidence at all. This restores the v5 read-model and evidence-engine captured from the running image (rescue/deployed-uncommitted-0816), including applyRecoveryGapClosureFacts, the round-robin drain, the component_stale repair reason, and publishConnectorListSummaryTerminalProjection -- the list-summary publisher whose absence from origin/main turned every source grey on an earlier deploy today. The checkpoint-less-participant fold fix is re-applied on top.

Connector code and manifest come from the worktree-pdpp-signal-connector branch, which was independently reviewed this session; registration in orchestrator.ts is included, without which the connector is invisible to the runtime. sigtop publishes only a Windows binary on its releases, so Linux is built from the pinned v0.24.0 source tag in a throwaway Go stage. Only the resulting binary, its ISC license, and a commit-exact SOURCE_URL are copied into the final image; Go itself is not. Without this the connector would fail at runtime with a missing binary on every self-hosted deploy, which is what shipping it on origin/main alone would have done. Rebased onto the v5 fold lineage deliberately: the connector branch was cut from origin/main at fold logic version 4, and deploying that against version-5 evidence rows fails closed on every source.

Without these the connector is only half-registered -- present but not wired into collection or conformance. Builds sigtop on golang:bookworm rather than golang:latest. The runtime image is bookworm (glibc 2.36) while golang:latest is trixie (2.38), so a binary built there loads on the builder and dies in the final image with 'GLIBC_2.38 not found'. Also installs libsecret-1-0 in the runtime stage: sigtop links it for Signal Desktop keyring access, and having only the -dev package in the builder produced a binary that compiled cleanly and failed on first use. The verification step is now a bare 'sigtop -v' with no '|| true', so a binary that cannot execute fails the build instead of shipping.

The registry validates that connector_id resolves to connector_key against the expected host, so the connector was rejected on every boot and never registered -- it was present in the image and invisible to the product. The reconcile log made that undiagnosable: it printed only the error code, 'invalid_request', with no field and no message. Diagnosing this one rejection cost several build-and-deploy cycles of guessing at plausible causes (listing tier, reachability capability, missing setup block, stream coverage_policy) -- all wrong.

Two places needed the same idea. seedFoldState now skips any checkpoint that is null OR zero when computing the floor. rowNeedsFoldParticipation now excludes a historical-refused row whose checkpoint is zero: the carve-out added earlier routed it to the checkpoint-lag predicate, and 0 < maxSeq is trivially true, so it rejoined every pass anyway.

Its SQLCipher key is stored encrypted in config.json behind Electron safeStorage and unwraps only through a session-bound OS keyring (kwallet6/gnome-keyring, Keychain, DPAPI). Tested against real data on this host, a container fails at four successive layers: file absent, then 'cannot connect to D-Bus session bus', then EOF on a uid mismatch, then an AppArmor denial once uids matched. Copying the database is insufficient -- the key is not in the file. Three changes: - becomes a first-class binding in runtime_requirements.bindings, and sourceKindFromManifestBindings resolves it to local_device. The engine now refuses server-side placement up front, through the same mechanism that already keeps browser connectors off the collector profile, rather than leaving the next person to rediscover this four D-Bus layers deep. - signal.json declares that binding with its rationale. - 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 stays proven via slackdump. The packaging rule this establishes -- sidecar packaging keys off the connector's placement bindings, not one uniform mechanism -- is recorded in design-notes/connector-sidecar-packaging-2026-08-17.md, along with the basic_text edge case (a keyring-disabled Signal stores the key unwrapped, which is a documentation note rather than a reason to ship an image stage). Signal remains local-collector-only with PATH/SIGTOP_BIN resolution and a clear install error. Connector code must not fetch executables at runtime; that acquisition story belongs to the registry's signed, ABI-tagged artifacts.

Raising max_wal_size to 8GB, min_wal_size to 1GB and checkpoint_timeout to 15min removed the warnings outright on the live instance. shared_buffers and effective_cache_size move off their 128MB/4GB defaults to modest values that are safe on a 4 GB VPS.

Root cause: runBoundedObservationPhases (connector-summary-read-model.ts) runs a "missing"-only repair phase before the "generic" phase that classifies dirty/stale/checkpoint-mismatch. missing's own batched discovery pays a fixed cost over the whole requested scope regardless of how many rows are actually missing -- including zero, which is the common case for an already-dirty, already-observed row. That discovery cost is not reserved against the round's shared cooperative deadline, so under load it can consume the entire budget before generic's own discoverCandidates ever runs. generic is the only phase that ever returns "dirty", so the round returns empty candidate counts and the row stays dirty=1/state=stale forever, invisible to every counter. Fixed the same way connector-maintenance-sweep.ts already closes the structurally identical walk-vs-acceleration starvation: alternate which phase gets first opportunity at the remaining deadline, giving generic a hard 2-round bound on how long missing can deny it a turn. The fold that existing participants depend on still always runs first, unconditionally, preserving the separately-tested "fold before slow generic repairs" contract. Added a regression test reproducing the exact production shape (many missing-evidence sibling connections inflating missing's discovery cost, one already-warm dirty row) and proving it converges within the alternation's 2-round bound. Tests: connector-summary-dirty-priority-starvation.test.ts (12/12), connector-summary-evidence-bounded-sweep.test.ts (8/8), connector-summary-evidence-engine-scoped-consumer.test.ts (5/5), connector-summary-source-revision.test.ts all pass; repeated runs show no flakiness. biome check clean on both changed files (one pre-existing, untouched runCursorWalk complexity warning remains, unrelated to this change).

A genuinely dead session (403/redirect) still fails with the same reddit_session_failed taxonomy. Falls back to the old DOM probe only for the credential-less manual hand-off, where no username is known yet. Left a comment instead of implementing the manual-handoff retry gap noted alongside this (ensureRedditManualSession/recoverRedditBlockedLogin give one shot, unlike amazon.ts's final-verify retry) — three existing tests deliberately assert sendInteraction is never called on the post-submit poll-timeout path as defense-in-depth for the credential-safety invariant, so that change needs its own pass rather than riding along here.

Desktop mouse input was unaffected. Root cause: the capture-phase pointerdown/pointerup gate in stream-viewer.tsx required `event.button === 0` for touch pointer events before forwarding them to the remote surface. Per the Pointer Events spec, `button`/`buttons` describe mouse-style button state and are not a reliable signal for touch — some touch input paths report a non-zero or non-mouse-like `button` on pointerup for a legitimate primary contact, so this gate silently dropped taps while leaving desktop mouse input (which does carry a meaningful button state) working. Scroll/rotate were unaffected because they don't route through this gate. Extracted the gate into stream-viewer-pointer-input.ts (matching the existing stream-viewer-geometry.ts extraction pattern) so it is unit-testable outside the component, and removed the touch/button check entirely — touch has no secondary button, so `button` must never gate touch forwarding. The mouse hover-move suppression (buttons === 0) is preserved unchanged. touch-action: manipulation was already correctly scoped to the remote-surface media element in stream.css, so it was not implicated.

But browser_surface_leases/browser_surfaces still held 21 rows from Aug 1-3 (an earlier setup flow's "#browser-phase" session capture), all cleanly torn down: leases released, surfaces stopping, none unhealthy or active. getConnectorBrowserSurfaceProjection counts any historical row as "this connector has browser evidence," so it fell through projectConnectorBrowserSurfaceEvidence's unhealthy/ready checks (both false for a stopped surface) into BROWSER_SURFACE_UNKNOWN_PROJECTION -- forever, with no run ever able to clear it. Confirmed fleet-wide: chase and usaa (also browser-phase connectors with zero ready/non-terminal surfaces left) show the same axes.remote_surface: "unknown", collapsing connection_health to state: "unknown" / pill "Not measured" even with a fully successful, complete-coverage run. getConnectorBrowserSurfaceProjection now takes manifestHasBrowserBinding and short-circuits to no-evidence (not_applicable) when the connector's CURRENT manifest declares no browser binding at all, before consulting any historical row -- the same "manifest declaration is a stable required-capability fact" pattern manifestRequiresBrowserSessionRepair already uses. ref-control.ts wires it from runtime_requirements.bindings.browser !== undefined. This does not touch the existing retired-history behavior for connectors that DO use a browser (chatgpt/usaa/reddit still correctly project unknown from stale rows) -- only connectors whose manifest never mentions browser at all skip the history check entirely. Added a test proving the pre-fix call shape still reproduces the stuck-unknown bug, and that passing manifestHasBrowserBinding: false resolves a Slack-shaped legacy-lease fixture to a healthy, none-axis headline instead.

But the messages DETAIL_COVERAGE was built from historicalMessageCoverage alone, dropping the forward pass's considered/covered -- the sibling message_bodies DETAIL_COVERAGE a few lines above already correctly sums both passes. On the live instance this showed up as messages: collected(451) > considered(431), reported as coverage: "unknown" on an otherwise clean, fully-covered run. Sum historicalMessageCoverage + forwardMessageCoverage for both considered and covered, matching message_bodies. Extended the existing "scheduled runs advance historical pages while forwarding new mail" test to assert the messages DETAIL_COVERAGE equals the sum of both passes; reverting the fix alone fails it (actual {considered: 1, covered: 1} vs expected {considered: 2, covered: 2}). Not touched: attachments' terminal_gap. That's driven by 52 durable connector_detail_gaps rows (16 quarantined + 4 temporary_unavailable, both genuine provider-side gaps, plus 32 too_large rows stale since 2026-08-03 predating the size-cap policy that now correctly excludes too_large from gap creation). The 32 stale rows permanently poison the terminal count even though current collection behavior is correct -- this needs a product decision on cleanup/lifecycle for orphaned terminal gaps, not a blind patch, so it's flagged as a follow-up rather than fixed here.

A dialog that rendered even slightly slower than 2500ms -- network jitter, client-side render variance -- read count 0, which emitDialogUnexpectedShapeDiagnostic reports as export_dialog_unexpected_shape. tryExportLadder treats that phase as fatal and aborts every remaining candidate date-range retry on the first occurrence, so the whole run gets classified source_structure_changed -> export_affordance_missing, an "actionable" severity gap that mapCoverageAxis turns into terminal_gap for the ENTIRE connection -- even though accounts/account_stats/inbox_messages were complete and the credit-card/statements gaps were unrelated, already-correctly-classified retryable PDF-download timeouts. Live evidence ruled out a genuine USAA site change: today's runs for this connection alternated between clean success and export-affordance failure across two different phases (no_export_affordance, then later export_dialog_unexpected_shape) with inconsistent marker counts -- the signature of flaky render timing, not a stable redesign, which would fail the same way every run. Same class of defect as the already-fixed Chase current_activity hydration-wait bug (fix-chase-current-activity-hydration-wait): a fixed timing assumption trusted as proof of "structure changed" rather than "hasn't rendered yet." Replaced the fixed sleep + one-shot count with a bounded waitFor({ state: "visible", timeout: EXPORT_DIALOG_DELAY_MS }) on the date-range select. A slow-but-real render now succeeds; only a select that never appears within the same time budget still falls through to the existing unexpected-shape diagnostic and Escape path, unchanged. Added a regression test asserting a slow-but-real render is treated as ready, not a structure change -- verified it fails against the pre-fix code and passes with the fix. USAA suite: 233/233 (1 pre-existing skip) pass. tsc --noEmit clean. biome check clean.

The connector registers a direct-CDP streaming target once, via the run-target registry, when it emits its manual_action interaction — confirmed by production logs: PUT /admin/runs/:runId/interactions/:interactionId/streaming-target returns 200, and the first two mint attempts for that run succeeded with backend "cdp". The viewer's presentation-bearer session has its own short TTL (independent of the interaction's timeout_seconds, which can run up to 30 minutes). `schedulePresentationExpiry`'s timeout fired `invalidateForInteractionResolved` on bearer expiry, which defaults to force-unregistering the run-target registry entry via `terminalizePresentation`'s default `cleanupTarget`. That conflated "the viewer's token expired" with "the interaction is over": the manual_action interaction was still pending (owner hadn't responded), but the registry entry it depended on was deleted anyway. Every subsequent mint attempt then hit `streaming_companion_unavailable`, permanently, with no recovery short of re-running the connector — this is the reported "Open browser" 500. The code already had the right pattern one path away: the `stream_session_superseded` branch in `mintStreamSession` passes `cleanupTarget: () => Promise.resolve()` with a comment explaining the direct-CDP target is owned by the interaction, not the bearer/session. Apply the same no-op cleanup to the bearer-expiry path, so a fresh mint after expiry re-attaches a new companion to the same still-registered target. Added a regression test that registers a direct-CDP target, mints a session, advances a fake clock past the bearer TTL to fire the expiry timer, and asserts the registry entry survives (no `run_target_force_unregistered`) and a subsequent mint still succeeds. This is a general reference-server fix, not a neko-specific one — neko-backed runs already keep their lease-scoped surface alive independently and are unaffected (leases are keyed by run_id at BrowserSurfaceLeaseManager, not by the presentation bearer).

The console's stream-reach-diagnostics classifyReason() only mapped 401/409/410; every other status, including this 503, fell to the `default: return "unknown"` branch, whose copy is "Couldn't reach the browser stream after several tries." That phrasing reads as a network/reachability problem and is exactly what hid the real, actionable STREAMING_COMPANION_UNAVAILABLE error behind generic wording — the same outage this branch is fixing on the server side. Map 503 with probeCode "streaming_companion_unavailable" to the existing companion_unavailable reason (its copy already says the right thing: "The browser session is no longer running on the server. Start the browser step again."). Other 503 codes (e.g. the managed n.eko window-settle probe's managed_surface_window_settle_unavailable) still fall to unknown rather than being collapsed into companion_unavailable, since they are a different, currently-unclassified condition. Also address the underlying pattern, not just this one instance: the `unknown` reason now appends the observed status code to its message ("... (server responded 500)") so the next unmapped status is visible in the UI instead of silently reusing identical generic copy the way this one did. Updated the two existing tests that asserted the old exact-verbatim `unknown` message. Added tests: 503 + streaming_companion_unavailable classifies as companion_unavailable; 503 with an unrelated/absent code still classifies as unknown (so a different real 503 condition isn't mislabeled).

Traced via connector_state (coverage_diagnostics) and git history, not guessed: their agent builds (0.0.0+d53f67fa2034 from 08-03, +378a2ba7a7ae from 07-25) predate 5e4493cdb/59557c1e5/4d9e6b7e4 (08-10), the commits that taught claude_code/codex to report coverage_diagnostics rows for derived_messages/derived_attachments/derived_memory_notes (claude_code) and derived_messages/derived_function_calls (codex) at all -- not merely to tolerate them once already reported (292e02b9a, already deployed). Their committed snapshots structurally cannot contain those rows, so parseCoverageDiagnosticsStateSnapshot's missingStores check correctly computes non-empty and deriveLocalCoverageAxis correctly refuses to call the connection reliable. This is genuinely-unproven coverage, not the server refusing to read a proven snapshot: pre-5e4493cdb, these three streams were never measured by ANY store for claude_code, not even the parent sessions/projects scan (confirmed by reading the commit's own before/after). ref-connectors-local-coverage-green's existing comment already documents this as intended behavior. Per the project's coverage-honesty rule, `unknown` is the correct verdict here, and fabricating `missingStores` tolerance for old builds would assert coverage that was never measured. The fix ships once these four devices' agents update past 4d9e6b7e4. Simon VM's absent run_history is a separate, non-bug observation: its enrollment revoked 2026-05-20 (dexp_90b7966a095308d7) was superseded by a still-active, still-heartbeating enrollment (dexp_9ed7a42ed38a505c, last heartbeat today) that has ingested continuously since; run_history simply never carries rows for push-based local-device ingest the way it does for scheduler-polled connectors, and its retention only reaches back to 2026-08-13 regardless. What IS fixed: deriveLocalCoverageAxis returned reliable:false with no way to tell WHICH precondition failed, so diagnosing this required manually tracing parseCoverageDiagnosticsStateSnapshot by hand. Added unreliableReason (invalid_cursor / generation_mismatch / malformed / no_authoritative_inventory / no_committed_snapshot / duplicate_stores / missing_stores / unexpected_stores), computed in the same short-circuit order the reliable conjunction already checks, so the reason always names the first failed precondition. Purely additive -- never changes what counts as reliable, only labels an existing refusal. New test asserts the very distinction this diagnosis needed: missing_stores (genuinely unproven) vs generation_mismatch (a different kind of refusal), plus that a reliable result carries no unreliableReason at all. node --test test/ref-connectors-local-coverage-green.test.ts: 31/31 pass.

Three defects made that state undiagnosable: - The executor spawned children with stderr set to "ignore", so a native onnxruntime abort or V8 fatal error printed to a discarded stream. Pipe it and forward to the parent log instead. - The child registered no signal handlers, so shutdown depended on Node's default disposition, which never fires while the main thread is blocked in a synchronous native call. Add a cooperative SIGTERM/SIGINT handler that stops admitting queued work. This cannot rescue a child already wedged in native code, but it removes the no-handler gap. - Signal's manifest declares a desktop_session binding that the placement resolver already understood but the manifest validator's allowlist did not, so every shipped-manifest validation failed. Two independent lists had drifted; add the key to the validator. Also add signal to the local-collector expectations and to the enrollment form's connector list -- it was absent from /sources/add, which the console consistency test correctly flagged.

Measured on the live instance, the next envelope started 163-185ms after the previous run completed, three times in a row on one connection. MAX_RECOVERY_CONTINUATION_ENVELOPES bounds how many envelopes run (12). It does not bound how fast, so a connection with pending gaps can burn the whole budget in seconds. For a connector whose sign-in sends the owner a one-time passcode, that is up to 12 pushes in a burst -- the owner reads it as the app spamming their phone. Add a per-connection minimum interval between continuations. Progress is unchanged; only the cadence is.

Its stated exit condition was unreachable. A bare terminal spine event never marks the evidence row dirty -- markConnectorSummaryEvidenceDirty is called only on a changed record write and from owner-action routes -- and stream_facts_event_seq advances only via the fold's own write, which the carve-out excludes the row from. Circular: the row could never notice a genuinely new event. The defect is not the carve-out but the write path beneath it, which froze the checkpoint at its stale prior value for a non-current-generation row instead of advancing it to the high-water the drain actually searched through. manifest_generation_changed rows already stamp that boundary; historical rows did not. Advance it for both. writeParticipantStreamFacts already floors its write at Math.max(writeSeq, effectiveCheckpoint), so this can only advance the checkpoint, never regress it. Checkpoint-lag becomes meaningful again: false immediately after refusal (silence costs nothing, the starvation guard holds) and true once a real new event pushes maxSeq past it. Found on production: three rows sat in this state, one of them an active connection reporting ProjectionReliable=false with no way to recover.

Rows already sitting at checkpoint zero had no path back. The carve-out in rowNeedsFoldParticipation never read `dirty`, and that predicate is the only gate into the fold's participant set, while the fold's write path is the only thing that advances stream_facts_event_seq. So the exclusion was closed: marking such a row dirty cleared the flag through the repair path while terminal_fold_participants stayed at zero. Verified on production against three rows in that state, one an active connection reporting ProjectionReliable=false with no way to recover. Add `dirty` as the re-entry term. This costs one pass per stranded row rather than reopening the every-pass livelock the carve-out ended: once the row participates, the write path stamps its checkpoint off zero and this clause can never match it again. The new test is production-shaped -- a pre-existing zero-checkpoint row with a large event log ahead of it -- and asserts both halves of the contract: it converges once dirtied, and it goes quiet again afterward.

The backend reported it registered and owner_actionable the whole time; only the console withheld it. Key the preview arm on availability rather than on the one disposition that broke. `available_now` already means "the owner can add an account now from a shipped surface", which is exactly the property this gate wants, so a future preview disposition resolving to it cannot reintroduce the same invisibility. `requires_server_setup` and `not_available_here` still withhold the offer. Adds a tier x disposition matrix test asserting the observable contract -- whether an entry is offered -- rather than restating the branches. Under the old condition exactly the preview local-collector case fails and the other six pass, so it pins the defect rather than the implementation. Also updates connection-modality's pinned local-collector allowlist, which had not been regenerated since the connector was added.

The RI host always shapes that field as an object -- pdppError writes {code, message, type} -- so String() on it produced the literal "[object Object]" for every host-side failure. On this instance that discarded the cause of 24 quarantined Gmail attachment gaps, each recorded as "blob upload failed (503): [object Object]". The 503 itself may well be transient, but nothing downstream could tell, because the only evidence was a stringified object. Read .message out of the object shape, falling back to a plain string field and then to statusText. The uploader is shared by groupme, imessage, signal, whatsapp and apple_photos, so all of them stop throwing away host error detail. This restores diagnosability; it does not retry the existing quarantined gaps. Those are sticky by design and need an explicit requeue once this ships, at which point the real 503 cause becomes visible for the first time.

The owner reported that message sitting on screen for an hour. The read was never the problem. "Destination stream closed early" comes from React's RSC streaming writer when the HTTP response closes while the Flight stream is still being written -- the /_ref/connectors read had already returned 200 in ~1.2s. Most plausibly the page poller's router.refresh() superseding an in-flight render, or the tab throttling the connection. There is nothing to fix at the fetch layer; refFetch already awaits its json and sets cache: no-store. So the boundary renders the same skeleton loading.tsx uses, and once a last-good timestamp exists, a dimmed "Updated Xm ago" beneath it. A teardown now looks like an ordinary page load. Retry is unbounded with capped backoff (300ms to 15s) -- no terminal give-up state, no manual Retry button. The retry counter lives at module scope, not in state: the boundary remounts fresh on every catch, so a useState counter resets to zero each time and never actually backs off. The invariants test pinned the old copy. It now pins the property the copy was violating -- the sources view renders no failure language in any state. Seven sibling segments (/syncs, /audit, /grants, /event-subscriptions, /device-exporters, /schedules, /deployment) plus the console root share this pattern and mostly do not even auto-retry. Same fix applies; not in this commit.

All four were running collector binaries predating the derived_messages/derived_attachments/ derived_memory_notes stores, so their coverage snapshots structurally could not contain what the parser requires -- missingStores is non-empty, the snapshot is refused, and the axis is honestly unknown. The health model was right to withhold green: coverage really was unproven. What it failed to do was distinguish "this collector is too old to prove coverage" from "no evidence yet", which reads identically to the owner and sends them looking at the server. Report coverage_unknown_stale_collector with an update_connector remediation when the refusal is specifically a missing-store shortfall. No condition is weakened; an out-of-date collector still cannot turn a source green, it just says so. One of these connections also never emitted CollectionSucceeded, for the same underlying reason -- its build has no terminal-collection call at all, so no run.completed event was ever written and terminal facts could never converge.

Seven sibling segments and the console root had the same defect and mostly worse: a full-viewport takeover with "Couldn't load X" and a Try again button, and unlike /sources, no auto-retry at all. A stream teardown the owner should never have learned about became a dead end requiring a click. Each leaf boundary now renders the skeleton its own loading.tsx uses -- list or detail, matched per route -- and retries unbounded with capped backoff. A teardown is indistinguishable from an ordinary load. The root boundary is deliberately NOT unbounded. The dashboard already fault-isolates its own reads through safeRead, so anything reaching the root is either the same stream race or a genuine unhandled fault, and this codebase has no error reporting beyond console.error. Retrying a real crash forever would erase the only signal an operator has. It stays quiet for five attempts, then falls back to the existing panel -- strictly better than showing that panel immediately, without hiding a hard failure. Only the backoff arithmetic is shared. Each route keeps its own module-scope counter: one shared counter object would let a failure on /grants corrupt the backoff on /schedules. The counter must live at module scope because Next remounts the boundary on every catch, so useState resets to zero and never actually backs off. components/segment-error.tsx is now unused by every former caller. Left in place; deleting shared files belongs in its own change.

The cause was the string [REDACTED]. The redactor exists for a good reason -- it strips bare tokens of 24+ characters from connector-authored messages so an unlabelled API key in a stack trace never lands in a durable row. But it matches on shape, not content, and "heb_verification_code_not_provided" is 35 characters of clean snake_case. The rule ate the answer. The unredacted channel already existed: TerminalError.code flows to connector_error_code without passing through the redactor, and boundConnectorErrorCode already validates it against a strict charset. Nothing populated it on this path. establishSession's catch -- the one choke point every connector's ensureSession failure crosses -- now promotes a thrown message to code when it matches that same charset. A compound message with spaces or colons still fails the test and still gets only the redacted message, so nothing PII-shaped rides through. Because the fix is at the shared boundary it also covers amazon and chase, which throw the same convention. USAA throws human sentences and is deliberately untouched; changing its error text is its own change. The real cause survived only in spine_events.known_gaps, which is where I had to go to read it.

They would not survive a worktree cleanup, and nobody but their author could see them. Three are from today's production work and record findings that outlived the incidents that produced them: - failure-diagnosability: five failures in one day whose causes were destroyed before anyone could read them. Includes the corrected scale (three real sites, not the 246 a bad grep suggested) and the finding that the redactor is an entropy heuristic, not a PII control -- it eats clean reason codes and passes an email address through untouched. - source-state-truth: why a source holding 2.4M live records renders as "Not measured", and why a finished manual import can never be green under a model where every condition is required. - summary-evidence-projection-controller: an independent reviewer's terminal design for the maintenance sweep, after four starvation bugs of the same shape in twenty-four hours. The other three predate today and were simply never committed.

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?

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.

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.

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`. Both `REASON_CODES` objects are + unexported `as const` with no derived type. `codeToStatus` + (`routes/ref-error-status.ts:89`) is `Record`, 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 +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?

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.

Two are fixed here; the other two need one instrumented run, which this also arms. Credit-card billing and balances each carried two gaps created by a single crashed run. The next full run scraped both cards successfully, but unlike transactions -- which has a complete serve-then-recover lifecycle -- these two streams had no recovery-emission path at all, so the gaps could never clear no matter how many successful runs followed. Generalized the transactions pattern to cover them. The inbox stream identified 13 rows and covered zero. Every row is dropped when date_short is empty, and all 13 failing at once reads as column-index drift in the fixed-position scraping rather than 13 bad rows -- but the correct mapping cannot be guessed without the real DOM. It now emits an inbox_rows_unresolved skip result instead of failing silently, and captures the listing DOM so the next run answers it. Statements identified 10 of 10 and downloaded none, four times, with the download listeners armed and seeing nothing for 45 seconds. The listeners are page-scoped and this file already documents that Playwright downloads never reach context-level listeners, so the likely cause is the Download menuitem opening a page the listeners cannot see. Added a context-level new-page watcher, which tests that directly. Credit-card export was already instrumented and needs no change; it was simply never run with capture enabled. Worth recording: collectUsaa never calls reportStreamFailure, so all three defects surface as skip results and the run reports success. Capture must therefore be armed with PDPP_CAPTURE_FIXTURES, not PDPP_CAPTURE_ON_FAILURE, which would delete the evidence for exactly this run.

His session cookie is valid until 2026-11-16. He was never logged out. navigateAndProbeSession fired /api/auth/session exactly once, three seconds after page load, and checkSession collapsed every failure -- network blip, non-2xx, Cloudflare interstitial -- into "logged out". One transient false opened the full credential-login flow, which hit an app-approval prompt on an account that was already authenticated. Sometimes that auto-resolved; sometimes it hung the whole 900-second assistance budget and failed the run. Either way the owner got a notification he had to act on. Now the probe retries four times, 1.5s apart, before concluding a session is dead. Six seconds worst case against a fifteen-minute hang plus a login. Two diagnosability defects found underneath it: run_history.failure_reason was hardcoded null on every completed run -- buildSuccessOrFailureRecord read a type that never declared the runtime's failure_message even though the object always carried it. That is why every failed row all day had an empty reason and the cause had to be dug out of spine_events. Widened the type and read the field. The runtime's own resolution never carried a specific assistance-timeout message either; that lived only in the terminal spine event via duplicated logic that had drifted from its sibling. Unified both onto one helper and corrected a timeout mislabelled as failure_origin: connector when the runtime caused it. The RS ingest path classified per-record storage failures onto an in-memory outcome object and logged nothing, so a deterministic 503 on a 500-record batch was invisible. It now logs the real cause, connector instance, run and stream, without leaking into the client 503 or the mutation.rejected event.

Line 1 of its packed local-device-client.js imports @pdpp/reference-contract, which is not in dependencies and does not exist on the registry. It resolves through the pnpm workspace link, so it works for every developer and no user. Three of the owner's collector machines were broken by it today. Two gates should have caught it and neither could: validate-package.ts asserted no @pdpp/* appears in the DECLARED dependency sections, and separately checked that RELATIVE import specifiers resolve inside the tarball. Nothing looked at bare specifiers in the packed code, so an undeclared workspace import passed clean. @pdpp/cli and @pdpp/mcp-server had the identical hole. pack-install-run already existed -- it packs, installs into a clean project outside the workspace, and executes the binary. It would have caught this outright. It was not in local-collector's verify. mcp-server had the same omission; cli and read-core were already wired. Now every packed .js/.mjs/.d.ts is scanned for static imports, re-exports, dynamic import() and require(), each bare specifier resolved against Node builtins and the manifest's real dependencies. A private @pdpp/* culprit names this incident in the failure message. The check is generic on purpose; a @pdpp/-specific regex would only catch the one we already know about. Proven on the real artifact rather than a mock: reintroduced the offending import, built, and watched the packed-tarball validator fail; reverted, rebuilt, watched it pass. Two pre-existing drifts fixed because they blocked the verification: signal missing from the expected-connector lists, and mcp-server not handling npm 12's object-keyed pack --json shape, which local-collector already handled. Disclosed and not fixed: pack-install-run's iMessage sample smoke reports records_seen 0 while the outbox shows sent 1. Reproduced on a clean tree, so it predates today. It is the last thing standing between local-collector and a fully green verify.

Since credentials were re-added on 08-17 every run has failed at session establishment, zero records, seven in a row. The failure was reddit_session_failed: reddit_login_post_submit_failed on a fully automated run with no owner interaction requested at all -- the form filled and submitted correctly, then the connector never found a session. Post-submit, the 2FA check asked whether an OTP field was visible using a hardcoded one-second isVisible probe, while the pre-submit username field gets a ten-second waitFor. Reddit paints the OTP step in a second client-side render pass that routinely takes longer than a second after domcontentloaded. When it does, the connector concludes there is no 2FA, never asks the owner for the code, and spins out a dead ninety-second cookie poll before failing. The owner is never prompted, so from the outside it looks like the login simply did not work. Wait for it properly, five seconds, matching the pattern the username field already uses. The regression test scripts the OTP field attaching at 1.2s: before the fix zero interaction requests are sent and the run throws; after, the owner is asked for the code. Also fixed the shared makeLocator fixture, whose fake waitFor ignored the state option -- a genuinely hidden field would have passed a waitFor({state:"visible"}) check, which would have made this test lie. The separate manual-login failures look like a real Cloudflare challenge on a browser profile whose cookies were wiped by the 08-16 delete and recreate. That is an external condition, not a defect, and the existing manual handoff is the right mechanism for it.

That sentence is false. These are the residue of a delete: on 2026-08-16 the connections were removed with a proper cascade and tombstones written, then re-created under a different binding-key prefix so the resurrection guard would not fire. What is left has records from real past runs, no credential row, and no schedule. Reconnecting would not resume anything -- it would create a new connection. The owner has said plainly these are history. CredentialsValid is right that no credential exists. The bug is the remediation copy derived from it, and where that copy is shown. The server already computes source_visibility: "hidden_from_sources" for exactly this shape, and the Sources list already honors it. That exclusion was simply scoped to one consumer, so the same row still generated a live prompt on /syncs and the dashboard. Read the field in the work-item builder too. No health condition changes and no server change -- the right primitive already shipped, one more caller just needed to use it. Distinct from the finished-manual-import case (Google Maps, WhatsApp), which needs a genuine terminal state because its question is unanswerable rather than merely misrouted. A companion test proves a visible needs-owner connection with the identical verdict still surfaces, so the fix suppresses the fragment and nothing else.

Permission denied, a missing table, a dropped connection and genuine data loss all collapse to one string, and the gate exits non-zero having destroyed the reason. It appeared twice. Worth recording because it proves the rule is not about TypeScript or error objects -- it is about any transform that keeps the fact of a failure and discards which failure. Their session also reframes the scope. Four of their five findings were nothing-reported-it rather than it-broke: Postgres crash-recovering behind RestartCount 0 and green healthchecks, meilisearch crash-looping behind a healthcheck that probed only its own port, promtail dying on a full disk silently, and pg_dump exiting 0 with an unrestorable dump. Our five were the narrower shape -- something reported a failure and destroyed its cause. The wider half is worse, because the narrow one at least leaves a row to investigate. So the invariant gains a second clause: a component whose failure is survivable must still be observable. A supervisor that restarts or a probe that recovers does not make a process healthy, and something must say so. This does not widen the remediation. Still three sites; the 439-catch measurement and the 97%-benign classification stand. It widens what counts as evidence that a component is healthy, which is a monitoring question.

Deleting the fleet-wide record count (a5505bb59) was necessary and did not fix it. Two failures remained, both from one cause: spine_events has an index covering four terminal event types and nothing covering the rest. Discovery's maxLifecycleSeq query groups MAX(event_seq) by connection with no event_type filter, so it falls outside that partial index and does a parallel seq scan -- measured 1.1s against 1.4M rows on production, against a 500ms per-unit floor. It is cancelled every pass, and because discovery's seven queries share one failure boundary, the cancellation aborts the batch before anything is classified. The second is deterministic and was the dominant one. Enrolling Signal today created a connection with zero spine_events and no evidence row. Its repair runs MAX(event_seq) WHERE connector_instance_id = -- same missing index -- and times out even with zero matching rows, because an unindexed predicate cannot be pruned by absence of matches. The row therefore never gets evidence, and every walk-tranche page reaching it throws "Cannot publish connector list summary without canonical evidence", which isExpectedProjectionRace does not forgive. On walkFirst ticks that killed the acceleration tranche outright -- the only path that reads the dirty rows. Add the general (connector_instance_id, event_seq) index on both backends, following the precedent the terminal-scoped index already set. EXPLAIN confirms both queries now plan index scans. SQLite needed a follow-on: with two candidate indexes and no partial-index selectivity stats, its planner started preferring the general one for terminal-scoped folds, about 1.5x slower. The three terminal fold queries now carry an explicit INDEXED BY hint. Disclosed: connector-summary-sweep-stuck-page-starvation.test.ts now fails its FAIL-BEFORE case because the queries are genuinely fast enough that its hardcoded 100k-row backlog no longer starves anything. The starvation it pins is less severe rather than gone; the calibration needs revisiting by whoever owns it. Left untouched rather than guessed at.

Both are source_kind=manual, paused, with zero runs ever. They are finished one-shot imports that will never refresh, so Fresh and SourceCoverageComplete, which both presuppose a future run, can never be satisfied. The owner reads that as broken. The carve-out was tried twice and reverted (e47ffc632, 8b1838e85) because it contradicts the generation fence, and a test locks the current behavior in as correct. So this does not force them green. Fresh becomes not_applicable -- not true, since calling a 2023 export fresh would be a second lie -- and coverage stays required. not_applicable already existed as a condition status whose own doc comment says it exists "so the projection stops encoding certainty as doubt", but it was confined to presentation. This makes it load-bearing: a condition that does not apply counts as satisfied, one that is merely unknown does not, and inapplicability may only come from durable evidence that the question is meaningless. That last clause is the whole safety property, and two tests pin it -- a source with the identical shape but no acquisition declaration stays grey. Inapplicability is derived from source_kind, a CHECK-constrained fact written once at creation, never inferred from an absent run. A second gap the design note had not anticipated: rendered-verdict and owner-state read the raw freshness axis and evidence.source directly, so they would have rendered "Not measured" regardless of the condition. They now read the typed Fresh condition instead. These two rows will not resolve today. terminal_facts_historical forces ProjectionReliable false at step 1 of 14 and returns before the healthy classification at step 14 is reached. That is a separate upstream defect in the evidence fold, disclosed rather than worked around.

The conformance roster still listed it as development-only and its own integration test asserted the same, failing three tests against a manifest that was right. Steam's mutation table still expected steam_response_malformed when GetRecentlyPlayedGames omits games entirely. Commit 3ccca8000 deliberately made that valid: the documented shape for an account that has played nothing in two weeks is a response with total_count and no games array. The test asserted behavior the code had intentionally shed. Replaced with two explicit cases so the fix cannot silently widen -- absent means empty, present-and-not -an-array still throws. The iMessage smoke was the interesting one. records_seen 0 while the outbox showed sent 1 looked like a miscount; it was neither a miscount nor a connector defect. The synthetic fixture pinned its dates to a fixed Apple epoch base around March 2023. On 2026-08-09, two days after that fixture was written, an undeclared-scope default of 30 days landed -- deliberate, owner-protective behavior that gives an enrollment declaring no boundary a recent-history window. Every one of the fixture's 500 rows fell outside it and was correctly filtered. The single sent item was the checkpoint, not records. So a correct feature silently invalidated a correct fixture, and the smoke had been failing on a true negative ever since. The fixture now computes its base from wall clock rather than a constant. pnpm verify for local-collector is green end to end for the first time: 204 unit tests, validate:package, and all six fixture smokes -- three of which had never run at all, because iMessage crashed before reaching them. Flagged, not fixed: google_messages and google_takeout pin timestamps the same way and are equally time-scopable. They pass today by luck of the window.

He is right, and it was in four places. Three faults, not one. It is developer language on an owner surface -- he is running self-hosted software, so being told the code is broken is both unhelpful and faintly accusatory about software he chose to run. It names who is at fault instead of what happens next. And it reads as total failure on a source that is still holding real data and still collecting most of its streams. The file already had the right register one line away: "Coverage gap needs review" for the softened case. The hard case now says "Some data from this source can't be collected" -- a fact about his data rather than a diagnosis of ours. The unmeasured case drops "a connector update is needed" for "Some data from this source isn't being measured yet", which is also more honest, since evidence can still arrive. The line worth getting right is that some of these states genuinely are our defect and not something he can act on. The copy must not invite an action he cannot take, and must not imply everything is fine when coverage really is partial. Naming the consequence does both. Vaguer is not kinder -- "Something went wrong" would be worse than what was there. These stay specific. One of the four is a string-equality guard that branches on the CTA text, so it had to move in lockstep. That coupling is pre-existing and fragile; left as found rather than refactored under a copy change.

It has never been addable: no connection, no tombstone, no records. The manifest ships and the connector is complete, but public_listing.tier was development, and three separate gates withhold that tier outright -- sourceSetupAvailability returns not_available_here, isRunnableAddOffer never reaches an offer branch, and sourceSetupAction returns null, so even a rendered card would have no button. Confirmed against the live page: chase and signal appear in the markup, venmo does not. Development was an honest tier when it was set -- the connector's own header comment says no live network call has proven it against a real account. That is still true. But it is the same situation Signal was in, and Signal is listed at preview with a rationale saying exactly that, so the owner can perform the first real run. Venmo has 70 passing tests across parsing, schema, redaction, fixtures, and the auth-flow retry-safety guards. So: preview, not supported. The Preview disclosure already tells the owner these paths have not completed live validation, which is the honest framing for a connector that is code-complete and unproven. Field-by-field against chase, the closest browser-bound comparator, the tier was the only structural gap. Everything else is legitimate connector-specific content. One existing test pinned Venmo at development to verify the legacy-UAT exposure gate. Repointed it at spotify, which is genuinely development-tier, so the gate still has a valid subject.

This is why: PDPP_BROWSER_PROFILE_ROOT is /var/lib/pdpp/browser-profiles, baked into the image, and the owner stack mounted nothing there. Every browser profile lived in the container's ephemeral writable layer and was destroyed on each restart. Twelve deploys in one day, twelve logins. It affects every browser-backed connector -- ChatGPT, Reddit, Amazon, Chase -- not just the one he noticed. And it compounded a separate bug fixed earlier today, where a single-shot session probe manufactured re-auth demands against a live cookie: that one cried wolf, this one made the wolf real. deploy/docker/docker-compose.yml already mounts pdpp-data:/var/lib/pdpp. The owner stack simply never did, and neither declared the volume. Both now match. Recovered rather than reset: the running container's 110MB of live profiles, including a Reddit session the owner had just solved a captcha for, were archived out and restored into the new volume before the mount was added.

Both have zero terminal run events, ever, fleet-wide -- verified against spine_events. The fold's own documentation says such a row converges to current via the bootstrap path and never reaches terminal_facts_historical at all. These sit at historical anyway. The bootstrap path is unreachable in production. The sweep folds pages of about 25 instances at a time, and almost any page contains some connection with real terminal history, so the scope's max terminal seq is never null and the zero-history branch never fires. The existing lock-in test only exercised a singleton scope, which is why it never caught this. Then seedFoldState seeds each row's generation-current flag from its own stored reason code. Once anything stamps a zero-event row historical, that seed reads false on every later pass, and a row with no events has an empty drain, so nothing can ever flip it back. It rewrites the same wrong verdict forever. Seed true when the instance has no attributable terminal events at any generation, overriding a stale stored reason. That restores the documented behavior without touching the generation fence: a row with genuine historical events still seeds false and still forces ProjectionReliable false, which the lock-in test verifies. The alternative -- exempting classifyUnreliableProjection for sources whose acquisition is complete -- is the carve-out reverted twice already. It would let a real generation-mismatched fact pass as reliable for any manual source, which is the thing the fence exists to stop. No migration needed. Both rows are already behind the fleet high-water, so they re-enter on the next pass and self-heal.

He did this twice today. Both times the work was wasted. His session was fine. I pulled the Chromium cookie DB out of the live profile and read it: token_v2, loid and session_tracker all present, last_access stamped at exactly the moment of failure. Nothing in the connector or the browser launcher clears cookies or resets a profile on failure. The login succeeded; the connector just never looked again. manualBrowserLogin calls its probe exactly once, immediately after the owner's interaction resolves. Reddit wires isSessionLive straight into that. With no credentials configured, isSessionLive does a real navigation to old.reddit.com and checks for a logout link -- which takes time right after a captcha redirect settles. The single check read a transient not-yet as a permanent no. Poll instead: 15 seconds, 3 second interval, overridable for tests. Same shape as the OTP fix earlier today, in the manual-handoff path rather than the automated one. Scoped to Reddit's two call sites rather than the shared browser-handoff helper, which chase, usaa and venmo also use and which has its own passing contract test. They may want the same treatment; that is a separate change with its own evidence. Sized by precedent, not measurement -- I could not reproduce a live captcha without the owner. If Reddit serves a different post-captcha shape, this fixes the timing but not that.

The verdict comes from the heartbeat, not the evidence. Its outbox carries one gap row from a failed attempt at 19:22:45 ("spawn tsx ENOENT"), superseded by the successful run a minute later. The collector reports any nonzero backlog as blocked, and deriveOutboxAxisFromHeartbeat's blocked branch looked only at dead letters, so a single piece of debris from a superseded attempt was indistinguishable from a genuinely unreadable exporter. Carve out the bounded case: dead letters zero, backlog known and at most three, no pending records, heartbeat not stale. Any of those failing keeps the old classification. An unknown backlog never qualifies, so an older collector build stays conservative. Also adds unfillableAccounted to the coverage evidence, so a caller that can prove every outstanding gap is permanently uncollectable -- a recorded byte size against a recorded cap, not an attempt count -- can report coverage complete with an honest reason rather than blocking forever on data that cannot be fetched. Retry exhaustion is deliberately NOT such proof: 117 failed attempts show the strategy has not worked, not that the item is impossible. Three anti-false-green tests pin that. Nothing populates unfillableAccounted yet; the read model that would is owned elsewhere. The runtime accepts the evidence, which is the slice that belongs here. Signal will not resolve until its collector heartbeats again -- its last is now stale past the threshold, and staleness still blocks, correctly.

Both are manual imports with zero runs ever and zero rows in connector_detail_gaps, run_history or acquisition_batches. Coverage evidence comes from a collection run; nothing will run again. The adjacent Gmail case looks identical from the pill and is not. Gmail has 32 terminal gaps each carrying observed_size_bytes against a recorded cap -- it measured its shortfall and can enumerate it. These imports never measured at all. Measured-and-provably-impossible and never-measured-and-never-will-be are different states and must not share a signal; asserting the former over an empty set is the false-green the anti-green tests exist to catch. I had been treating them as one design. An agent refused that framing on the evidence and was right. The line already in the code holds: Fresh can be satisfied by not_applicable, SourceCoverageComplete cannot -- it is gated by conditionIsTrue at connection-health.ts:1830. A completed import buys exemption from a freshness proof, never from proving it ingested what it claimed. So the answer is not to exempt coverage but to let an import prove it. connector-coverage-policy.ts already declares a snapshot_import_receipt strategy that nothing emits -- the placeholder is the design, unbuilt.

It has no notion of what a token means, so it also ate heb_verification_code_not_provided -- 35 characters of clean snake_case that was the entire answer to why a run failed. A tighter regex cannot fix this. tim_nunamaker_gmail_com is alphabetic snake_case too; the difference between a reason code and a personal detail is provenance, not spelling. So the connector declares its own reason tokens and those survive; everything else is still stripped by length. Disclosed and unchanged: the redactor already passes an ordinary email address through untouched. It is a high-entropy-string filter, not a PII control, and reading it as one is a mistake this note should stop. Also documents Signal in the local-collector runbook, which covered only Claude Code and Codex despite Signal shipping and collecting 6448 records today: the safeStorageBackend check, the sigtop build including the no-root deb-extraction path that was actually needed here, verification via check-database, SIGTOP_BIN, and the tsconfig packaging gotcha that shipped a collector able to advertise itself but not run.

No retry changes a 29MB attachment. Coverage could never complete, so the source was permanently red for data that cannot exist on this side. 73f1f7870 added the runtime flag. This computes it: read a connection's terminal gaps, and set it only when EVERY gap on a required stream carries durable per-item proof of impossibility. For these rows that is last_error_json recording an observed byte count against the configured cap -- two real numbers that do not change on retry. Gmail still does not resolve, and that is the correct outcome. Its attachments stream mixes those 32 proven rows with 5 temporary_unavailable rows carrying no evidence at all -- just attempt counts climbing from 37 to 117 over a month. Retry exhaustion shows a strategy failing, not an item being impossible. All-or-nothing holds: 32 of 37 is not proof, and a partial exemption would be exactly the false green the anti-green tests exist to catch. My own test caught a real bug before it shipped. The connection-level rollup first checked only streams already at terminal_gap, so a second required stream sitting at unknown was invisible -- terminal_gap outranks unknown in worst-wins, so it would have passed silently. A cross-stream leakage guard now pins it. Deliberately not extended to the two finished manual imports. They have no gap rows and no coverage evidence of any shape, which is never-measured rather than measured-and-impossible. Sharing a signal between those would assert proof over an empty set.

The probe fetches https://venmo.com/account from inside the page, which requires the page to actually be on a venmo.com origin because api.venmo.com only trusts that origin. ensureVenmoOrigin navigated there and swallowed the result with .catch(() => undefined), returning unconditionally. On a fresh profile the page starts at about:blank, so a single failed navigation left the credentialed fetch running from an opaque origin, and the browser threw its own Failed to fetch with nothing pointing at the navigation. Chase and Reddit swallow the same navigation failure and get away with it because they probe the DOM, which just times out into "not logged in". Venmo is the only fetch-based probe, so the same bug surfaces as an opaque transport throw. Now it checks the origin actually landed and throws venmo_origin_navigation_failed. Still retryable; the credential-safety invariant on the pre/post-submit split is untouched. The container can reach venmo.com fine -- 200 -- so this was never a network problem. Also finishes a fix I thought had already landed. 1eccc5488 let connectors declare reason tokens that survive redaction, but only wired them into scheduler logging, never into boundConnectorErrorMessage -- the function that redacts the message actually persisted. So venmo_probe_transport_error, 27 characters, was still eaten as a high-entropy false positive. The registry is now threaded into that call site, and the production string survives intact. HEB has the same shape and is deliberately not registered here; it is a one-line follow-up rather than something to slip into this change.

Both defects behind them were fixed today. The rows still had no path back: the requeue tool hardcoded reason = 'quarantined', so temporary_unavailable was unreachable by retry and by repair alike. Add --reason, defaulting to today's behavior, with an allowlist at the store layer rather than the CLI: quarantined, retry_exhausted, run_cap_deferred, temporary_unavailable -- every one a bounded-budget exhaustion on a signal never proven non-transient. Refused categorically: too_large, not_found, gone, permanent_forbidden, auth_failure. These carry durable proof of impossibility, and reopening a 29MB attachment against a 25MB cap would spin forever. The refusal throws before any database session opens, and the WHERE clause re-checks reason at write time so a row that changes class mid-flight is never swept up under the wrong one. Used it on the five: dry run matched 5 and wrote nothing, apply requeued 5, the 32 too_large rows untouched. The next Gmail run hydrated all five and they are now recovered -- the 503 really was transient. Gmail's attachments stream now holds only the 32 oversized rows, every one carrying observed-bytes against the configured cap, which the unfillable-accounted predicate reads as complete rather than blocking. It will read that way once deployed.

Running the predicate against those 32 live rows returns true. The page still said Degraded. Two paths build a connection's collection_report. The single-connection path passes a real per-stream proof map, read from the terminal gap rows. The list page calls loadPageProductEvidence, which reads per-instance COUNTS only and passed null. Downstream that null becomes an empty map, every lookup misses, and coverage_unfillable_accounted is false. The comment there was right that counts cannot support a per-stream verdict and that inventing one would be a false green. What was missing is that false is not 'unmeasured' -- it is a claim, and it was the wrong one. Give the batch path its own batched row read, chunked the way the existing count-batch read is, ordered identically so both paths see the same rows. Truncation is the load-bearing part. The query takes cap + 1 rows per instance; an instance that comes back over the cap is provably truncated, so its rows are dropped entirely rather than trimmed. Trimming would let a proven-only prefix report true while the one unproven gap sat just past the cap. A truncated instance stays null, which the projection already reads as not accounted. Both readers now call one extracted classifier, so the two paths cannot drift apart again -- that drift is the whole defect. Mutation-checked the tests are real oracles: restoring the null makes the parity test fail printing false against true, and replacing the truncation drop with a silent slice turns both truncation tests red.

It had derived complete for months. Commit 4161f5d7b fixed a real undercount two days ago: the messages DETAIL_COVERAGE denominator reported only the historical backfill, while the forward pass emits its own messages records through the same shared emitRecord. That fix summed both passes. Fifteen lines below, emitHistoricalContinuationSkip reports the same two numbers as proof the page was fully accounted for, and it was left on historical-only. isHealthyBoundedContinuation accepts a bounded page only when the continuation's considered/covered are identical to the fact's -- it binds a continuation to complete same-page facts. After the fix the pair differed by exactly the forward-pass count every run: 52/52 against 51/51 live, and 24/30, 35/36, 84/85, 115/116 back through the history. The identity check failed and the stream fell through to retryable_gap. The first fix was correct. It moved one of a pair. Hoist the summed counts into one local and feed it to both emissions. The sibling threads stream has never desynced because it does exactly this -- one variable, both call sites. Two copies of an addition are two things that can disagree, and this pair silently did. The existing test drove both passes and asserted the 2/2 denominator; it never asserted the continuation agreed. Added that assertion where the scenario already lived. Reverting just the two continuation arguments makes it fail with 1/1 against 2/2 -- one forward-pass record, the live shape. Connectors suite 4469 pass / 0 fail.

It had no knowledge of unfillableAccounted, so a stream whose terminal gaps are ALL proven impossible still derived terminal, which emitted a maintainer code_fix carrying terminal: true, which worst-wins tone rendered red. The health gate had learned the new fact; the disposition had not, and the two disagreed off the same evidence. That action was also noise on its face: maintainer-audience, satisfied_when none, for gaps already proven accounted for. A 29MB attachment against a 25MB cap is not a bug anyone can fix. Disposition resolves to complete, not a new value. complete has never meant 'no gap was ever recorded' -- deferred and inventory_only already reach it with a recorded reason for data that will not arrive. This is that claim with stronger evidence. The distinguishing fact stays on the coverage axis, which keeps reporting terminal_gap with its own reason, so the stream-health audit's proof gates (which require coverage complete AND disposition complete) cannot be falsely satisfied. Threading the boolean into the disposition alone was not enough -- worstStreamCoverageTone read the raw coverage axis independently and kept the pill red, and terminalStreamIds still named the accounted stream in affects. All three now share one predicate. Only terminal_gap softens. unsupported and unavailable are different claims and still derive terminal. One unproven gap among proven ones still derives terminal and still renders red -- partial proof is not proof. Mutation-checked: reverting the disposition guard fails 4 tests, reverting the tone softening fails 1, and reverting the affects exclusion survived until the oracle was strengthened to assert the exact list. 460 pass / 0 fail.

Postgres logged 9 statement_timeout cancellations in 10 minutes, all in the repair path, always the same two rows: cin_2de5ede05c8cc8d45935c414 (2.42M records) and cin_ece4bfe5096b8bf67a1468c2 (1.30M), together ~3.7M of the fleet's 5.46M. Nothing was ever marked failed, so the sweep looked quiet while the backlog never shrank. repairCandidatePostgres reads a per-connection canonical count and recency -- COUNT(*) and MAX(emitted_at) grouped by stream, filtered on connector_instance_id AND deleted = FALSE. Earlier in this same investigation that read was called "legitimate, necessary, cheap" without anyone measuring it against a real multi-million-row connection. Measured on production READ-ONLY with EXPLAIN (ANALYZE, BUFFERS), it takes 3.67-4.07 seconds and Parallel Seq Scans ~584k buffers (~4.5 GB). records has seven indexes and not one covers (connector_instance_id, deleted) without a stream predicate this GROUP BY cannot supply -- the closest, idx_pg_records_stream_cursor, orders deleted after stream. The existing per-connection catch was doing its job: a cancelled read defers instead of marking evidence failed. But "correctly deferred, forever, on the same two rows" is an unbounded backlog wearing the costume of a healthy sweep. Add the covering index on both backends -- (connector_instance_id, deleted, stream) INCLUDE (emitted_at) on Postgres, the same four columns on SQLite. Seeded at production-representative selectivity (one connection at ~4.4% of a 5.46M-row table) in a throwaway scratch database, never production DDL, the identical query plans a Bitmap Heap Scan at 83.7ms post-VACUUM against the 4.07s seq scan measured live. Built CONCURRENTLY for the same reason as idx_pg_lexical_search_scope_document: records already holds millions of rows and a plain CREATE INDEX would hold a table-wide write lock for the build. What this does NOT fix, stated plainly: the index helps in proportion to how small a slice of records a connection owns. Once one connection dominates the table, a seq scan is genuinely the cheaper plan and Postgres will ignore this index. That case needs a bounded, resumable read -- its own change, with a persisted partial-aggregate checkpoint -- not a wider index. This closes the gap for the fleet's normal shape and buys room, and I am not claiming more. Rejected: a maintained counter (retained_size_stream.record_count) carries no 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 -- reusing it would change repair's classification logic. Verified against real PostgreSQL: dropping the index reproduces the pre-fix schema and a contended records table cancels the repair read and leaves the row durably dirty; with the index the same contention window converges. 7 pass / 0 fail across the two canonical-count files and the lifecycle-seq sibling.

Scrolling worked fine, which is what made it confusing -- touch input was clearly reaching the page. Verified live against a Reddit reCAPTCHA checkbox: a touch tap at the checkbox's exact coordinates left it unchecked, while a mouse click at those same coordinates advanced the challenge. CDP's Input.dispatchTouchEvent does not reliably synthesize a click DOM event. Real touchscreen hardware gets one through the compositor's gesture recognizer; a synthetic touch event skips that path. remote-surface 1.5.2's neko backend already works around this for its own transport -- NekoPointerController calls it the canonical tap-to-click pattern, buttonDown plus buttonUp instead of native touch -- but dispatchCdpPointerInput in the cdp backend still branches on pointerType === "touch" into a raw dispatchTouchEvent for every pointer action with no such fallback. Rather than patch the installed dependency, reroute a touch or pen press-or-release onto the same mouse path a real mouse pointerdown/pointerup already takes, which is proven end-to-end above. clickCount: 1 is required there -- per the backend's own comment, a press/release without it doesn't focus inputs, toggle checkboxes, or follow links. pointermove is deliberately left on the touch path. The symptom itself (scrolling works) shows touch motion already reaches the page correctly, and CDP touch drag has no analogous click-synthesis gap to route around. Widening this to all pointer actions would change working behavior to fix something that isn't broken. The test file for this landed already and imports normalizeTouchPointerInputForCdp; until this commit the branch did not typecheck. 40 pass / 0 fail across cdp-companion and run-interaction-stream-cdp-adapter. Not verified: pen input specifically. It takes the same path as touch on the reasoning that neither reaches the gesture recognizer, but I tested touch.

It shipped the store tests but not the CLI-level ones that check that ordering claim, which is the part a caller actually depends on. Two cases, both spawning the real CLI with PDPP_DATABASE_URL and PDPP_TEST_POSTGRES_URL stripped from the child environment entirely. That absence is what makes them oracles: if the allowlist check ran after the database-url guard, or fell through to a connection, the process would exit complaining about a missing PDPP_DATABASE_URL instead of the reason refusal. The first asserts too_large exits 2 naming the refused reason and that stderr never mentions PDPP_DATABASE_URL at all; the second asserts an unrecognized reason is refused identically, so the allowlist fails closed rather than treating unknown input as permissible.

The surrounding try/catch could not help, because a hang is not a rejection. If Reddit accepts the connection and never answers -- plausible after repeated failed logins from one address -- the probe waits forever. Bound both layers: an AbortSignal on the inner fetch, and the repo's existing withDeadline on the evaluate. That helper exists in browser-handoff.ts for exactly this case; its comment already says CDP-backed reads can hang indefinitely with no per-call timeout. A third unbounded await turned up in the credential-less DOM fallback, where the goto timeout does not cover the following locator count. Bounded that too. A timed-out probe resolves to not-live rather than throwing, since 'I could not determine the session is live' leads to the same action as 'not live'. It stays distinguishable in diagnostics through a callback that fires only on timeout, so a tarpit never reads as a plain logged-out session. ensureRedditSession received no checkpoint function, so the watchdog could only name the last checkpoint the runtime itself emitted. Added the optional checkpoint field heb.ts already uses, wired through the existing EnsureSessionArgs, and emit before the probe -- the failure now names where it actually hung. The 15s retry bound was decorative: it was only checked between probes, so one hung call pinned it open forever. Mutation-checked: removing the outer deadline makes the four hang tests fail by genuinely hanging to the test timeout, and moving the checkpoint after the probe fails the ordering assertion in 103ms. 26/26 reddit, 145/145 auto-login.

The transport was fine; the probe was asking the wrong address. ACCOUNT_PROBE_URL pointed at https://venmo.com/account -- a web app route -- while collect() uses https://api.venmo.com/v1/account. Following that route from the container: venmo.com/account -> 302 account.venmo.com/account account.venmo.com/account -> 307 http://account.venmo.com:8080/ A fetch issued from an HTTPS page follows those hops and is refused at the final plain-HTTP one by the mixed-content rule, which reaches page JS as exactly TypeError: Failed to fetch. Deterministic across repeated requests and user agents, so not session-specific. It also means the probe never tested the session at all. It could not have returned an account id from that URL under any conditions, so the origin guard added earlier today was correct on its own terms but could never have fixed this -- a same-origin venmo.com URL needs no cross-origin grant. Point it at the API base the collector already uses, and apply the same two-layer bounding as the reddit probe, since the unbounded shape was present here as well. The bound stays phase-aware: a hung post-submit probe keeps its non-retryable name, so a timeout can never launder into a password resubmission. Not proven: the mixed-content mechanism is inferred from the verified redirect chain plus specified browser behavior, not observed in Patchright. The redirect chain itself is directly verified. A live run is what would settle it. Mutation-checked: restoring the old URL fails the URL test in 2ms, and removing the outer deadline makes both hang tests fail by hanging. 25/25 venmo, 178/178 across the reddit and venmo connector suites.

The two strategies carry identical proof obligations today, so this changes no verdict. It stops the manifest asserting a shape the import can never have, and puts google_maps under the same conformance rule as its siblings. Added a roster-driven conformance test that reads setup.modality, so a manual connector added later is covered without anyone remembering to add it. That guard already paid for itself by catching that connector_key uses hyphens, not underscores. Reverting the manifest turns 2 of the 3 tests red. The third stays green in both states by design -- it pins the roster itself, so a rename of setup.modality cannot silently empty the roster and let the other two pass vacuously. 176 pass across the reference-implementation projection, coverage-policy, manual-upload-route and manifest-validation suites; 44 across the connector coverage suites.

They never arrived because none were ever sent. H-E-B's sign-in is a single page offering a choice: a radio labelled 'Email me a one-time code' next to 'Enter password', with password already selected. The connector classified the surface by matching page text, and that label matches VERIFICATION_CODE_RE. It then asked the owner for a code and blocked until timeout. Both DOM captures from the failing run contain zero verification-code inputs; the only code-ish token on the page is the radio's own value. So the login form and the 'verification code page' were the same page all along, and the connector was reading an offer as a challenge. Classify verification_code only when the page can actually accept one: matching copy AND a usable code input, reusing the existing candidate count so the split-digit layout still counts. The chooser then falls through to the password path the module already handles -- no new surface, because the chooser is not a new page. Nothing selects the one-time-code radio; doing so would trigger a real code the owner would then have to go fetch, which is the opposite of the fix. passkey and captcha stay text-keyed on purpose. A false positive there costs a browser handoff; a false positive on verification_code costs a demand for a secret that does not exist. The prompt-site re-check initially survived its mutation, which meant it was unproven rather than defensive. It now has a test where the input vanishes between classification and prompt, sequenced off the connector's own checkpoint, and that mutation is killed. Also carries the passkey-enrollment surface from earlier work: H-E-B's post-login passkey upsell is declined automatically rather than mistaken for a challenge, with bounded retries and named errors on both failure modes. Removing both guards fails exactly the three new tests, with the stack showing the chooser routing into handleVerificationCodeSubmission. 38 heb, 141 connector suite, 149 auto-login, all passing. Not verified against the live site. The capture shows the chooser's submit button disabled, so there may be a separate reason that form never advanced; this change does not address that.

Any Chase page carrying that phrase could demand a one-time code Chase had never dispatched. On a grocery site that wastes the owner's time. On a bank it trains them to expect OTP requests they did not cause, and holds a browser session open against their bank while it waits. Gate classification on a visible, enabled code input. Chase's DOM carries a disabled hidden otp-input mirror, so presence in the DOM was never evidence -- it has to be usable. Accept a split per-digit layout as well as a single field, so a boxed redesign stays recognized rather than silently unclassifiable. Classification and the fill path now read one shared locator, so a page cannot be classified off an input the fill path would not find. The prompt site re-checks and throws a named error rather than falling through. Each guard was mutated separately, and each is killed by its own test. That mattered: with only the classification gate removed the no-input test still failed, but through the prompt-site guard rather than a fabricated prompt -- one guard was covering for the other's absence, which a combined mutation would have hidden. 8 chase tests, 153 auto-login, 174 chase connector suite, all passing. No live Chase contact at any point. No real capture of Chase's auth pages exists on disk, so the fixtures are synthetic, modelled on the module's own selectors. That is the limitation worth knowing: if the live OTP input is not matched by those selectors, this turns a fabricated prompt into a missed real one. Both selectors are unchanged from code verified live in April, and the failure mode is a named error rather than a demand for a secret.
