fix(routing,codex): latency scoring, workspace-denial classification, and a sync regression - #1848
Merged
Merged
Conversation
#1802 reported `ocx sync` overwriting a hand-edited config.json from stale server memory. The save path was fixed in 2.21.0 and the route now calls loadConfig() at its own boundary, so the reported clobber is no longer reachable -- but nothing pinned it. This asserts against the FILE rather than the response body, because the failure being prevented is the route persisting a caller-held snapshot back over the file. Driven red first by making the route save its caller-held config object: the hand-edited provider disappears and the test fails. Closes #1802.
…nto priority `optimize.latency` defaults to 0.55 -- the largest default weight -- and the normalizer includes it in the four-way sum. The evaluator then read only health, quota and cost, so whatever weight was allocated to latency fell into `priorityWeight = 1 - spentHealth - spentQuota - spentCost` and was multiplied by `configuredPriorityScore(index, total)`. That made a latency-optimized profile a declaration-order profile: the score decreases with index, selection is a strict-greater argmax, so the first declared candidate won regardless of measured latency. `components.latency` was never populated either, so the trace could not show it. Real latency was already measured, but only inside `healthScore()` scaled by `optimize.health`. That computation is now extracted as `latencyScoreFromEvidence()` and shared, so the health composite and the new standalone term cannot drift apart. An unmeasured candidate takes the neutral midpoint rather than 0. Scoring it 0 would make selection depend on which candidate happened to be exercised first, which is the same order-dependence by another name. Closes #1837.
A K12 account whose credential validates, whose warm-up succeeds and whose WHAM usage returns 200 still gets HTTP 403 `codex_workspace_access_denied` on a routed prompt. The classifier mapped every 403 to `credential`, which marked the account needs-reauth. Re-authentication succeeds, the next prompt fails the same way, and the loop repeats -- while the remedy offered cannot fix a workspace grant. The 403 is now split on structured evidence, not status. `quota-rejection.ts` reads an own-property `code` from the body (top level or under `error`) and reports `denial: "workspace" | "entitlement"`; that evidence travels on the existing `CodexUpstreamOutcomeMeta`, so the two `recordCodexUpstreamOutcome` sites in the Responses path pick it up without every caller changing shape. A `workspace` outcome records the failure so routing can prefer a healthier account, but does not call `markAccountNeedsReauth` and does not sweep thread affinity -- credential quarantine sweeps affinity because reauth is account-wide, and a workspace denial is not. Fails safe throughout: a 403 with no denial evidence, an unreadable body, a malformed body or an unknown code all keep the historical credential handling, so a genuinely revoked credential still prompts for reauthentication. Body reading reuses the existing bounded/duplicate-key-safe reader. Closes #1789.

Catalog convergence manufactured `reason: "disk"` for anything it could not recognize, in two places: the management adapter's catch and the management API route. So a malformed request and a genuinely full filesystem were indistinguishable, and both were reported non-retryable -- the operator was told to check storage for what was often a programming fault or lock contention. `CatalogDisposition` gains `request-invalid`, `admission` and `internal` alongside the existing reasons, so `disk` narrows to real IO. `admission` is the one class marked retryable, because contention is the failure worth retrying unchanged. The new `cause` field is deliberately NOT an error summary. Both of its fields are closed vocabularies: `kind` maps onto a fixed set rather than echoing `Error.constructor.name` (any thrown custom class names itself), and `code` is emitted only for a recognized errno token. An `Error.message` routinely carries paths, home directories and account identifiers, and `redactSecretString` masks token shapes but none of those, so message text is never forwarded. `normalizeCatalogDisposition` is updated in the same change. It is the privacy boundary that rebuilds the response from an allowlist of own data properties, so without extending it the new reasons and cause would have been silently dropped and the fix would have looked implemented while changing nothing. Regressions: an escaping factory error is `internal`, a TypeError is `request-invalid`, and an error whose message embeds both a home path and a token-shaped string produces a response containing neither. Closes #1784.

When a workspace 403 races with a 429 or arrives from a leased cooldown probe, replacing the entire upstreamHealth entry drops cooldownUntil, cooldown generation/source, and probe-lease fields. The account then becomes selectable immediately despite its still-live quota cooldown. Merge the workspace failure fields into the current health record and settle only an owned probe lease, as the transient and neutral outcome paths do.

Spending optimize.latency independently changes the documented public behavior, especially because latency has the default 0.55 weight. docs-site/src/content/docs/reference/configuration/routing.md:123 and several translations still state that latency is not independently scored and instead becomes configured-priority weight, so users will tune profiles against the opposite algorithm. Update the canonical English page and affected translations with this change.

test file so it verifies the generated Codex artifact contains the hand-edited
provider and modelCosts row, proving /api/sync consumed fresh disk
configuration. Keep the existing config.json disk assertion separately to verify
no-clobber behavior, or use a focused seam around syncModelsToCodex.
In `@devlog/_plan/260816_wave34_closeout/020_1837_latency.md`:
- Around line 56-58: Update the latency profile summary near the
declaration-order result to limit the no-behavior-change claim to profiles
explicitly setting optimize.latency to 0; do not characterize existing profiles
generally as unchanged because the default is 0.55.
In `@devlog/_plan/260816_wave34_closeout/030_1789_workspace_outcome.md`:
- Around line 46-48: Fix the ordered-list structure in the document by keeping
the code block and its continuation indented under item 2, so items 3 and 4
remain part of the same list and satisfy MD029.
In `@devlog/_plan/260816_wave34_closeout/040_1784_typed_cause.md`:
- Around line 30-33: Update the error taxonomy so request-invalid applies only
to validated external request or data-shape failures; classify programming
errors, malformed internal scope, and bad factory input as internal. Preserve
admission for retryable contention/database-busy cases and disk only for genuine
filesystem failures.
- Around line 25-26: Replace the string fields in the cause type with closed
CatalogCauseName and CatalogCauseDetail union types, and use them for the cause
property. Preserve runtime allowlisting in normalizeCatalogDisposition, and add
a test supplying a malicious prebuilt cause to verify normalization rejects or
sanitizes it rather than copying unsafe values.
In `@devlog/_plan/260816_wave34_closeout/050_1791_quota_windows.md`:
- Line 48: Revise the v1 hydration migration so legacy weekly* fields are not
assigned a synthetic 7-day duration; preserve their unknown or source-proven
duration and retain the correct exhaustion/recovery band. Keep monthly*
migration behavior unchanged, always write v2, and add a v1 K12 migration
assertion covering the legacy slot semantics.
- Around line 60-74: The cooldown recovery logic should use the latest reset
time among exhausted governing windows, since admission remains blocked until
all simultaneous blockers recover. Update the governing-window recovery
calculation and revise the corresponding test to assert the latest reset is
selected, while preserving the existing per-window exhaustion behavior.
In `@devlog/_plan/260816_wave34_closeout/060_1835_cli_mutation.md`:
- Around line 31-47: Update the mutation callback around validateConfigCandidate
and mutatePersistedConfig so validation failures are represented as the
established unavailable result with reason "invalid", rather than escaping as a
generic thrown error. Use a typed invalid result or dedicated validation error
that mutatePersistedConfig maps correctly, and add coverage for invalid set and
unset commands.
In `@devlog/_plan/260816_wave34_closeout/070_1823_signature_scope.md`:
- Around line 34-39: The caller in bridge.ts must await the persistence result

- Around line 36-41: Update the durability wording around atomicWriteFileAsync
to distinguish completed persistence from guaranteed crash survival, unless
implementing the stronger contract. If claiming crash durability, add file
synchronization before rename and parent-directory synchronization after rename

- Around line 19-23: Replace the raw captured request in the planned test with a
minimal sanitized tool/catalog fixture, or add an explicit construction seam
instead. Remove prompts, account identifiers, authorization headers, tokens,
OAuth material, and other credential-like fields; document the sanitization and
validate the fixture contains none before passing it through
createCursorRequest.

- Around line 27-31: Update the PolicyRequestEvidence preflight sizing flow to
use a conservative candidate-correct upper bound for input tokens, accounting
for differing tokenization and prompt overhead across candidate models. Ensure
each candidate’s routing decision cannot undercount relative to
checkInputAdmission while preserving the shared ADMISSION_TOLERANCE semantics
and explaining the tolerance in exclusion reasons. Add coverage for candidates
with different tokenization or overhead rules.

Chat-translated path, including successful admission substitution, missing-main
fail-closed behavior, and verification that the admission secret is never
forwarded upstream. Anchor the additions to the existing server-auth and
forward-admission-separation test suites, preserving the same security contract
as the HTTP, compact Responses, WebSocket, and Direct paths.
- Around line 47-51: The passthrough predicate for main with dedicated admission
must accept only a strictly validated, canonical real ChatGPT bearer that is
distinct from the admission credential; do not treat mere non-equality as
sufficient. Preserve validateForwardAdmissionCredential or an equivalent
validator until guaranteed substitution is established across all routes, and
add negative coverage for a second proxy secret, malformed or foreign bearer,
and admission-secret reuse.
In `@devlog/_plan/260816_wave34_closeout/101_1049_legacy_adoption.md`:
- Around line 18-20: The adoption recovery flow must distinguish an unpublished
pending row from one whose publication completed before the crash. Update the
pending-row state around publication to persist a durable phase or target
fingerprint, and have startup verify the target before replaying; ensure
recovery is idempotent and test the crash window after the final publication
write but before clearing the row.
In `@devlog/_plan/260816_wave34_closeout/102_1798_restore_merge.md`:
- Around line 17-25: Update the three-way restore merge to preserve a key when
baseline B lacks it and current C equals injected I unless retained ownership
evidence, such as a surviving marker, proves it was injected; otherwise leave it
unchanged and report it as unclassified. Add a regression test covering a
user-created value equal to I with no marker, ensuring it is not deleted.
In `@src/codex/routing.ts`:
- Around line 1694-1705: Update the workspace-denial handling in the
outcomeClass === "workspace" branch to merge with the existing upstreamHealth
record, preserving account-wide cooldown, cooldown-generation, and probe-state
fields. Release only probe leases owned by the current caller, including any

failure data; add a regression test covering a pre-existing cooldown followed by
a structured workspace denial.
In `@src/server/responses/core.ts`:
- Line 545: Update the pre-stream response handling around
codexDenialOutcomeMeta and poolRetryOutcome to classify recognized 403 workspace
denials before retry eligibility is determined. Route recognized denials through

| 3. **Carry it on the existing meta rather than changing every signature.** `CodexUpstreamOutcomeMeta` already reaches `recordCodexUpstreamOutcome` from every call site, so adding `denial?: "workspace" | "entitlement"` there means only the sites that can actually observe a 403 body need to populate it — in the Responses path, the two `quotaMeta` construction points. | ||

| 4. In the outcome handler, a `workspace` result must NOT call `markAccountNeedsReauth`. Record the failure in `upstreamHealth` so routing can prefer a healthier account, then return — deliberately NOT clearing thread affinity. Credential quarantine sweeps affinity because reauthentication is account-wide; a workspace denial is not, so existing bindings stay valid. No new per-route store is introduced: the health entry plus the preserved affinity IS the behavior change, which keeps the blast radius to the one wrong remedy. |

Make cause enforce the closed vocabulary.
The proposed type uses string for both fields, but lines 47-50 require closed values. This type permits a producer to pass a path, account ID, or raw error text. If normalization copies that value, the privacy boundary is bypassed.
Define CatalogCauseName and CatalogCauseDetail union types. Keep runtime allowlisting in normalizeCatalogDisposition. Add a test that passes a malicious prebuilt cause, not only an Error.message.

Persist publication state, or make recovery idempotent.
The pending row stores only the source-artifact fingerprint. If the process crashes after publication and before clearing the row, startup sees the same fingerprint but cannot determine whether publication already completed.
Unless publication is explicitly idempotent and target-verified, recovery can reapply or partially overwrite artifacts. Add a durable publication phase or target fingerprint. Otherwise, verify the target state before replaying publication. Test the crash window after the final publication write and before row clearing.
Context: the supplied #1049 plan requires resumable adoption without leaving a half-published home.

Add an ownership rule for the B-absent, C === I case.
Line 19 treats any current value equal to injected value I as injected. If baseline B did not contain the key and a user independently creates the same value after injection, the merge cannot distinguish that user value from the injected value and will delete it. This violates the safety requirement in Lines 23-25. Require retained ownership evidence for deletion, or preserve the key when B is absent and no marker survives. Add a regression test for a user-created value equal to I.

Preserve quota cooldown and probe state for workspace denials.
Line 1699 replaces the complete upstreamHealth record. If the account has an account-wide quota cooldown or an active probe lease, this write removes cooldownUntil, cooldown generation, and lease fields. A late workspace-denial response can then make a throttled account eligible again.
Preserve cooldown fields from the current record. Release only an owned probe lease. Also release an owned scoped probe lease, as the caller branch does. Add a regression test with a pre-existing cooldown followed by a structured workspace denial.

handling in the outcomeClass === "workspace" branch to merge with the existing
upstreamHealth record, preserving account-wide cooldown, cooldown-generation,

`config set`/`unset` read the disk snapshot OUTSIDE the mutation lock and then sent that whole older snapshot through `saveConfig`. A concurrent edit landing between the read and the write was silently reverted -- the CLI reported success while discarding someone else's change. The operation now runs inside `mutatePersistedConfig`, which reruns the callback against the latest validated disk state, so it is applied to what is actually there at commit time. No new primitive was needed; this one already existed. Two details the callback has to get right: - `changed` compares a snapshot taken BEFORE the mutation. Comparing after the write compares a value with itself, reports every no-op as a change, and bumps the config generation for nothing. - The committed object is REPLACED, not merged. `Object.assign` alone cannot remove a key, so `unset` would have reported success while changing nothing. Driven red against exactly that. Validation, the saved-value readback and the `codexAccountPriorities` pin release all moved inside the transaction with it -- leaving the pin clear outside would have reintroduced the same race for the pin. `import` is deliberately unchanged: it is an intentional whole-document replacement, and forcing it through patch semantics would silently merge where the user asked to replace. Closes #1838.

A K12-style plan sends a 5-hour primary window plus a 7-day secondary. The parser folded the primary into `weeklyPercent` whenever it was not explicitly monthly, so the 5-hour bar was reported AS the weekly quota and the real weekly reading -- the one that actually gates the account -- was discarded. The primary window is now skipped for the weekly slot when it DECLARES a duration shorter than a day, letting the 7-day secondary land there instead. A window with no declared duration is deliberately unchanged: older WHAM payloads omit `limit_window_seconds`, and inferring a duration there would reclassify every legacy account. That is why the discriminator is "declares a sub-day duration" rather than "is not seven days". This is the narrow correctness half of #1791. The broader generic-window storage (keeping every upstream window with its own reset, rather than two named slots) touches ~158 call sites across quota, routing, capacity, CLI and API surfaces, and is planned separately in devlog/_plan/260816_wave34_closeout/050_1791_quota_windows.md. Refs #1791.

| Store windows as an array, but keep the PROVENANCE the current shape encodes.

Define the governing mapping for every quota slot.
StoredQuotaWindow.governing is per-window, and Line 60 permits multiple simultaneous blockers. The plan only states that the legacy monthlyIsPrimaryWindow flag is preserved. It does not define how primary, secondary, and tertiary slots become governing windows.
Add a mapping table for ordinary two-window payloads, K12 payloads, and tertiary payloads. Add tests that prove supplementary windows cannot block admission.

Treat non-finite latency as missing.
At src/routing/health.ts:384-386, NaN bypasses the undefined check. The clamp returns NaN, which propagates into healthScore and the evaluator total. Since NaN > bestScore is false, an eligible candidate can remain unselected. Use p50 === undefined || !Number.isFinite(p50) and add a regression test.

Forward the request abort signal to denial parsing.
codexDenialOutcomeMeta calls classifyCodexPreStreamRejection without a signal. If the client disconnects while a 403 body stalls, this added clone read can continue until its timeout.

Summary
First three units of the Wave 3/4 closeout, plus the plan unit they came from.
#1802 —
/api/synccannot clobber a hand edit. The 2.21.0 save-path fix plus the route-boundaryloadConfig()already closed the reported clobber, but nothing pinned it. Adds a regression that hand-editsconfig.jsonafter the server is running and asserts against the FILE, since the failure being prevented is the route persisting a caller-held snapshot back over it. Driven red first by making the route save its held config: the hand-edited provider disappears.#1837 —
optimize.latencyis actually spent. It defaults to 0.55 (the largest default weight) and is normalized into the weight sum, but the evaluator read only health/quota/cost, so the latency allocation fell through intopriorityWeight * configuredPriorityScore(index)— i.e. declaration order. A latency-optimized profile silently became a declaration-order profile, andcomponents.latencywas never populated. The existing p50 scoring is extracted aslatencyScoreFromEvidence()and shared with the health composite so the two cannot drift. An unmeasured candidate takes the neutral midpoint, not 0, because scoring it 0 would reintroduce order-dependence by another name.#1789 — a workspace denial is no longer a credential failure. A K12 account whose credential validates and whose WHAM usage returns 200 still gets 403
codex_workspace_access_deniedon a routed prompt; the classifier mapped every 403 tocredentialand marked the account needs-reauth, so re-authentication succeeded and the next prompt failed identically forever. The 403 now splits on structured body evidence (allowlisted codes, bounded/duplicate-key-safe reader, own-property lookup), carried on the existingCodexUpstreamOutcomeMeta. A workspace outcome records health but does not set reauth and does not sweep thread affinity — credential quarantine sweeps affinity because reauth is account-wide, and a workspace denial is not. Fails safe: no evidence, unreadable body, or unknown code all keep today's handling.Also lands
devlog/_plan/260816_wave34_closeout/, which documents the verified state behind the remaining units. That plan corrects an external roadmap written against a stale snapshot — several symbols it names (materializeCodexUpstreamAuth,CatalogConvergenceError, the snake_case replay keys) do not exist, machinery it misses does (mutatePersistedConfig,OcxReasoningReplayIdentity), and its central claim that an admission secret leaks upstream is not reachable at this SHA.Closes #1802.
