Motivation

Background and data-plane entitlement resolves (for example GET /v1/models, catalog sync, and convergence) can refresh or rewrite the native auth.json while native-main lifecycle, recovery, or profile-switch drains intend the physical native identity to stay untouched. A refused claim also takes down Pool discovery with it.

Description

  • Adds model-entitlement-admission.ts plus withNativeMainCredentialAdmission in native-main-admission.ts, applied at five sites: retained-sync, convergence, serve-options /models, CLI startup discovery, and ensureCodexEntitlementFreshness.
  • Dev already fences the refresh write internally via its exclusive claim, so this relies on dev''s claim ordering rather than wrapping a second shared claim (which would self-deadlock credential commits).

Tests

  • bun test: 8/8 new admission tests, 64/64 entitlement suite, 540 pass across admission/convergence/auth-api/claim batches.
  • bun x tsc --noEmit: clean.
  • Note: 6 timeouts in codex-catalog-sync-hardening reproduce identically on the unmodified origin/dev baseline — pre-existing environment issue, not a regression.

Review readiness checklist

This PR stays in draft until every box below is ticked. Tick all four boxes once the requirements are met:

  • All CI tests are green on my local testing.

  • I pushed my PR to the latest dev commit.

  • I resolved all correct Codex and CodeRabbit findings.

  • My PR is ready for review.

Summary by CodeRabbit

Bug Fixes

  • Improved model discovery and entitlement checks when the primary account is unavailable, in use, or undergoing recovery.
  • Pool-based models remain discoverable during primary-account credential issues.
  • Model refresh operations now avoid unavailable credentials and retry with eligible accounts when appropriate.
  • Startup, catalog synchronization, convergence, and model-listing flows now apply consistent account-admission handling.

Tests

  • Added coverage for account admission, fallback discovery, credential failures, and entitlement refresh scenarios.

📝 Walkthrough

Walkthrough

The change adds native-main credential admission for Codex entitlement discovery. Entitlement resolution and freshness refresh can exclude the main account when admission is unavailable. Startup, catalog, convergence, and /v1/models paths now use the admission-aware resolver.

Changes

Native-main entitlement admission

Layer / File(s) Summary
Native-main admission fence
src/codex/native-main-admission.ts
Adds withNativeMainCredentialAdmission and its dependency seam. The function acquires a native-main claim, retries with MAIN_CODEX_ACCOUNT_ID excluded when admission is unavailable, and recognizes native credential-unavailable errors.
Admission-aware entitlement resolution
src/codex/model-entitlement-admission.ts, src/codex/model-entitlements.ts
Adds resolveAdmittedCodexModelEntitlements. Existing freshness work filters excluded accounts before credential snapshots, forwards lease release callbacks, and uses the admission fence when the main account is included.
Admission-aware discovery callers and validation
src/cli/index.ts, src/codex/catalog/retained-sync.ts, src/codex/convergence.ts, src/server/index/serve-options.ts, tests/codex-model-entitlement-admission.test.ts
Startup, catalog sync, catalog convergence, and /v1/models use the new resolver. Tests cover claim refusal, fallback discovery, credential errors, caller-supplied credentials, excluded accounts, and freshness admission behavior.

🟡 Minor · Acquire native-main admission before resolving the identity vector. · model-entitlements.ts:990-993

src/codex/model-entitlements.ts:990-993
🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Acquire native-main admission before resolving the identity vector.

ensureCodexEntitlementFreshness calls identityOf(MAIN_CODEX_ACCOUNT_ID) before refreshCodexEntitlementWorkset acquires admission. That identity lookup calls getMainAccountToken(), which reads auth.json. A denied admission therefore excludes main only after the lifecycle-sensitive read has already occurred.

Move the single withNativeMainCredentialAdmission call to encompass identity-vector construction and the refresh operation. Filter excluded accounts before calling identityOf, pass the exclusion through the workset, and remove the admission call from refreshCodexEntitlementWorkset. Keep the outer admission held through the actual credential snapshot. Ensure credential-ownership errors reach that outer admission so its Pool-only fallback still works.

Correct the stated cross-process locking guarantee.

The process-local lease covers the credential snapshot and upstream entitlement request. getValidMainAccountToken acquires its existing cross-process exclusive claim only when the snapshot requires an auth.json refresh. That claim is released before the entitlement request, so it does not cover the complete read and possible refresh.

Suggested change
* owns the physical credential. When main is admitted, the process-local lease
* and cross-process shared claim cover its complete read/possible refresh.
* owns the physical credential. When main is admitted, the process-local lease
* covers the credential snapshot and upstream entitlement request. If the
* snapshot needs to refresh auth.json, getValidMainAccountToken acquires its

Release the native-main lease before the Pool-only retry.

The fallback excludes MAIN_CODEX_ACCOUNT_ID, so it does not read the native-main credential. However, line 88 awaits the Pool-only operation before finally releases the lease. The active native-main turn therefore remains counted while Pool credential discovery and entitlement requests run. Profile switch and recovery drains wait for that count to reach zero and can time out on unrelated upstream work.

   try {
     return await operation(NO_EXCLUDED_ACCOUNT_IDS);
   } catch (error) {
     if (!isNativeMainCredentialUnavailableError(error)) throw error;
-    return await operation(NATIVE_MAIN_EXCLUDED_ACCOUNT_IDS);
   } finally {
     lease.release();
   }

모델 목록을 다시 받을 때 기본 계정(__main__)의 auth.json을 함부로 고치지 않게 막는 PR입니다. 카탈로그 동기화, 수렴, GET /v1/models, CLI가 켜질 때 모델을 찾는 곳, 자격 신선도 확인. 이 다섯 군데가 같은 문을 탑니다.

문은 이렇게 동작합니다. 복구 중이거나 프로필을 바꾸는 중이면 기본 계정은 빼고 풀 계정만 봅니다. 기본 계정을 봐도 되면, 보는 동안 이 프로세스 안의 대여(lease)만 잡습니다. 다른 프로세스와 파일을 나누는 자물쇠는 여기서 잡지 않습니다. 그 자물쇠는 getValidMainAccountTokenauth.json을 고칠 때만 잠깐 잡고, 고친 뒤 바로 놓습니다. 바깥에서 또 잡으면 자기 자물쇠에 자기가 막힙니다.

테스트는 대여를 못 받으면 기본 계정을 빼는지, 자격 오류면 풀만 다시 보는지, 그 밖의 오류는 그대로 던지는지를 봅니다. base는 dev입니다. 같은 수정을 겹쳐 닫을 다른 열린 PR은 없습니다.

src/codex/native-main-admission.ts withNativeMainCredentialAdmission - 자격 오류가 나서 풀만 다시 볼 때도 기본 계정 대여를 아직 안 놓습니다. 재시도가 finallylease.release()보다 앞입니다. 프로필 전환은 getNativeMainProfileRequestCount()가 0이 될 때까지 최대 10초를 기다리다가, 안 끝나면 MAIN_REQUESTS_ACTIVE로 실패합니다 (src/codex/native-profile-api.ts withMainRequestDrain). 풀 모델 목록을 인터넷에서 받는 동안 그 수가 1로 남습니다. 기본 계정 파일은 이미 안 읽는데도 전환이 시간 초과됩니다.

성공한 경우도 같습니다. 대여가 토큰을 읽은 뒤의 모델 목록 요청까지 덮습니다. modelsForCredentialauth.json을 다시 쓰지 않습니다. 파일을 지켜야 하는 구간은 getValidMainAccountToken까지입니다.

src/codex/model-entitlement-admission.ts 주석 - "프로세스 안 대여와 프로세스 사이 shared claim이 읽기와 갱신 전체를 덮는다"고 적혀 있습니다. 바로 옆 withNativeMainCredentialAdmission 주석은 shared claim을 일부러 안 잡는다고 하고, exclusive claim은 갱신 중에만 잡혔다가 모델 요청 전에 풀립니다. 구현이 맞고 이 주석이 틀립니다.

src/codex/native-main-admission.ts isNativeMainCredentialUnavailableError - 주석은 다른 프로세스가 claim을 잡고 있거나, 그 파일시스템이 claim을 못 하거나, auth.json이 중간에 바뀌었거나, 갱신이 거절된 경우만 말합니다. 코드는 NativeProfileError 전부(INTERNAL_ERROR, VAULT_INVALID, MAIN_REQUESTS_ACTIVE 포함)를 그 경우로 칩니다. 지금 이 길에서 실제로 나는 건 claim 두 코드와 갱신 오류 쪽이지만, 다른 코드가 섞여 나오면 풀만 성공한 것처럼 삼킵니다.

메인테이너의 판단이 필요한 지점

MainAccountTokenRefreshErrortransient(갱신 네트워크가 잠깐 죽은 경우)도 기본 계정을 뺀 성공으로 바꿉니다. 그 한 번의 카탈로그에서 기본 계정만 가진 모델이 안 보일 수 있습니다. 다음 주기에 다시 보면 됩니다. 그 빈칸을 허용할지는 정책입니다.

대여를 토큰을 읽은 직후 놓을지, 모델 목록 요청이 끝날 때까지 잡을지도 정해야 합니다. 파일만 지키면 되면 읽기가 끝난 뒤 놓아야 프로필 전환 10초가 모델 API에 묶이지 않습니다.

설명의 체크리스트에서 "latest dev에 올렸다"는 아직 비어 있고, PR은 draft입니다.

너의 추천

풀만 다시 보는 호출은 lease.release() 다음에 두세요. 성공 경로도 토큰을 받은 직후 대여를 놓고, 그 다음 모델 목록을 받으세요. 주석은 exclusive claim이 갱신 중에만 잡힌다고 고치세요. NativeProfileErrorNATIVE_MAIN_CLAIM_BUSYNATIVE_MAIN_CLAIM_UNAVAILABLE만 거르세요. 머지 전에 latest dev에 다시 올리세요.

Address review findings on the admission fence: the lifecycle lease now covers only the credential read — the operation releases it via releaseMainLease as soon as getValidMainAccountToken settles (success and credential-error paths alike) and before any upstream roster fetch, so a profile drain never waits on network work while the turn is still counted. The Pool-only retry also runs after release. isNativeMainCredentialUnavailableError now falls back only for NATIVE_MAIN_CLAIM_BUSY / NATIVE_MAIN_CLAIM_UNAVAILABLE; other NativeProfileError codes propagate. Correct the model-entitlement-admission comment to match the actual locking guarantee.

Pushed 018373e43 addressing the review findings (branch rebased onto origin/dev @ bd55ab7a3):

  • src/codex/native-main-admission.ts — the lifecycle lease now covers only the credential read. withNativeMainCredentialAdmission hands the operation a releaseMainLease callback; the operation invokes it as soon as getValidMainAccountToken settles — on the success and credential-error paths alike — and before any upstream roster fetch. The Pool-only retry now also runs after lease.release(), so withMainRequestDrain never waits on network work while the turn is still counted.
  • isNativeMainCredentialUnavailableError — falls back to Pool-only only for NATIVE_MAIN_CLAIM_BUSY / NATIVE_MAIN_CLAIM_UNAVAILABLE; all other NativeProfileError codes (MAIN_REQUESTS_ACTIVE, VAULT_INVALID, INTERNAL_ERROR, …) propagate.
  • src/codex/model-entitlement-admission.ts — corrected the locking comment: the process-local lease covers only the credential snapshot, and the cross-process exclusive claim is held only inside the auth.json refresh write.

추가 리뷰 · 우선순위 28 / 80

018373e는 지난 리뷰에서 고치라고 한 세 가지를 넣은 커밋입니다.

기본 계정 대여는 토큰을 읽는 동안만 잡힙니다. getValidMainAccountToken이 끝나면 바로 놓습니다. 토큰을 받아도 놓고, 자격 오류가 나도 놓습니다. 풀 계정만 다시 찾는 일은 그 다음에 시작합니다. 모델 이름을 인터넷에서 받아 오는 동안에는 이 대여가 없습니다. 프로필 전환이 모델 목록 요청 때문에 10초를 기다리다 실패하는 길은 닫혔습니다.

주석도 코드와 같아졌습니다. 이 문은 다른 프로세스와 나누는 자물쇠를 잡지 않습니다. 그 자물쇠는 auth.json을 고치는 순간에만 getValidMainAccountToken 안에서 잡혔다 풀립니다.

오류도 좁혀졌습니다. NATIVE_MAIN_CLAIM_BUSYNATIVE_MAIN_CLAIM_UNAVAILABLE만 풀 계정으로 넘어갑니다. INTERNAL_ERROR, VAULT_INVALID, MAIN_REQUESTS_ACTIVE는 삼키지 않고 그대로 밖으로 나갑니다. 테스트가 그 순서를 확인합니다.

PR은 초안이 아니고, 준비 체크 네 칸이 채워져 있습니다. 기준 브랜치는 dev입니다.

src/codex/native-main-admission.ts withNativeMainCredentialAdmission - 지난 지적 세 개는 여기서 닫혔습니다. 재시도 전에 대여를 놓고, 토큰 읽기가 끝나면 같은 경로로 놓으며, NativeProfileError는 claim 두 코드만 거릅니다. 이 커밋이 새로 어긋뜨린 줄은 없습니다.

메인테이너의 판단이 필요한 지점

MainAccountTokenRefreshErrortransient는 그대로입니다. 갱신 네트워크가 잠깐 죽으면 이번 목록에서 기본 계정만 빠지고, 풀 계정 목록은 성공으로 끝납니다. 기본 계정만 가진 모델이 한 주기 안 보일 수 있습니다. 다음 주기에 다시 보면 됩니다.

토큰 갱신 자체는 아직 대여 안에 있습니다. 갱신 대기는 최대 30초입니다. 프로필 전환은 10초에서 포기합니다. 모델 목록 대기는 빠졌지만, 갱신이 10초를 넘으면 전환은 여전히 MAIN_REQUESTS_ACTIVE로 실패할 수 있습니다. 이 시간은 지난 추천(토큰 함수가 끝날 때까지 잡기)에 남아 있는 창입니다.

dev 끝은 이 브랜치보다 커밋 두 개 앞에 있습니다. oauth 로그인 상태 분리(#5220)와 정적 정책 이전(#5174)입니다. 이 PR이 고친 파일과는 겹치지 않습니다.

너의 추천

이 경계로 머지하면 됩니다. transient는 한 주기를 건너뛰게 두세요. 30초 갱신과 10초 전환의 차이는, 전환이 실제로 그 창에 걸리는 걸 본 다음에 줄이세요. 머지 버튼이 최신 dev를 요구하면 그때 받으면 됩니다.

Approved on the current dev merge head. The native-main lease is released immediately after credential acquisition, only claim-busy/unavailable outcomes fall back to pool discovery, and the focused regressions preserve fail-closed behavior for other profile errors. Merge only after the new Cross-platform, Service lifecycle, and React Doctor checks are green.

지난 리뷰(018373e) 이후에 바뀐 것은 dev를 이 브랜치로 받은 머지 커밋 cf3ad98 하나뿐입니다. 이 PR이 직접 고친 파일 여덟 개(admission 문, entitlement 호출 다섯 곳, 테스트)는 그 머지에서 한 줄도 안 바뀌었습니다. 앞에서 닫힌 세 가지(대여를 토큰 읽기 직후 놓기, 풀만 다시 볼 때 대여를 먼저 놓기, claim 오류 두 코드만 거르기)도 그대로입니다.

머지로 들어온 것 가운데 이 길과 가까운 것은 #5135입니다. account-store가 토큰을 새로 고친 뒤 세대(generation)를 넘기는 handoff를 넣었습니다. 자격 갱신 비행 안에 붙는 일이지, 이 PR의 native-main 대여 경계는 건드리지 않습니다. 지금 브랜치는 dev보다 뒤처지지 않습니다(ahead 3, behind 0). 기준 브랜치는 계속 dev입니다.

CI는 이 머지 푸시 기준으로 아직 돌아가는 중입니다. CodeRabbit의 최근 통과 기록은 머지 전 커밋 기준입니다.

메인테이너의 판단이 필요한 지점

지난번에 남긴 두 가지는 그대로입니다. transient 갱신 실패를 한 주기 동안 기본 계정만 뺀 성공으로 둘지, 토큰 갱신(최대 약 30초)이 프로필 전환 대기(약 10초)보다 길 때 MAIN_REQUESTS_ACTIVE가 남을 수 있는 창을 지금 줄일지입니다. 이번 머지가 그 답을 바꾸지는 않았습니다.

CodeRabbit이 말한 ensureCodexEntitlementFreshnessidentityOf(MAIN) 선행 읽기도 아직 있습니다. workset을 고르기 전에 getMainAccountToken()auth.json을 읽을 수 있고, admission은 그다음 refreshCodexEntitlementWorkset 안에서 잡힙니다. 쓰기 펜스는 아니어서 이 PR의 본래 목적(갱신·쓰기가 라이프사이클을 깨는 것)과는 결이 다릅니다. 읽기까지 문으로 묶을지는 별 결정입니다.

너의 추천

이 상태로 머지하면 됩니다. CI만 초록이 되면 됩니다. transient와 30초/10초 창, identity 선행 읽기는 후속 이슈로 남겨도 됩니다. 이 머지가 이 PR의 경계를 다시 깨지는 않았습니다.

The exact-head CI is red on two deterministic layout gates, so I am withdrawing approval for cf3ad983781dafc42fc1159987be5c7d066eed47.

Both Linux test 1/4 and test 4/4 report the new tests/codex-model-entitlement-admission.test.ts as unresolved (tests/test-layout.test.ts:48 and tests/test-layout-tooling.test.ts:262). The runtime change may still be sound, but the new suite was not registered in the repository-owned test layout/expected fixture, so required CI cannot schedule and validate it consistently.

Please add the test file to the correct shard in scripts/test-layout/layout.json, refresh the checked fixture expected by the tooling test, and run both layout tests plus the focused entitlement suite. Then re-run full exact-head CI before requesting approval again.

…on and add privacy-bounded cache diagnostics (#5268)

* fix(codex): preserve cache affinity across model detours

Carries #5209.

A gated-model detour under pool.cacheAffinity + the quota strategy evicted a
cache-warm shared binding on a threshold crossing (a hint), before the account
was actually exhausted. The three shared-state/affinity preservation
predicates now use the 100%-exhaustion boundary via
hasCodexSharedStateQuotaHeadroom, matching live-binding quota re-evaluation.

* fix(reasoning): scope learned reasoning-effort refusals to credential identity

Carries #5145.

A learned upstream refusal was persisted under a destination-wide key
(provider, model, effort), so every credential reaching the same destination
inherited it. Each learned fact is now bound to a one-way SHA-256 digest of
the active credential; the support row key becomes a JSON array; the snapshot
advances to version 2 and legacy destination-wide rows are ignored on load.

* fix(cursor): isolate live roster and Max Mode evidence by account

Carries #5229.

Cursor pooled accounts shared module-level singletons for the Claude
wire-spelling map and the Max-Mode evidence set, so a discovery recorded
under one credential could rewrite the wire id or arm ultra for a request
resolved under a different account. Both maps are now keyed by a non-secret
sha256 scope over the upstream destination and credential, and a
provider-scoped evidence entry is dropped when its model cache clears.

* fix(codex): fence entitlement credential refreshes behind admission

Carries #5214.

Background and data-plane entitlement resolves (catalog sync, convergence,
serve-options /models, CLI startup discovery, ensureCodexEntitlementFreshness)
could refresh or rewrite the native auth.json while native-main lifecycle,
recovery, or profile-switch drains intend the physical native identity to
stay untouched, and a refused claim also took down Pool discovery. Adds
model-entitlement-admission.ts plus withNativeMainCredentialAdmission in
native-main-admission.ts, applied at the five sites; the test file lands in
the codex-integration domain registered in the layout map.

* feat(usage): show cache metrics by model

Carries #4793.

The Usage page's Models table now shows input tokens, output tokens, cache
hits, cache writes, and cache hit rate for each model; providers without
cache telemetry render an em dash. Includes translations for all supported
GUI locales, dashboard documentation, and a rendered GUI regression test.

* test(codex): move cache-affinity detour cases to a sibling under the file-size cap

codex-routing.test.ts sits exactly at its file-size cap; the carried #5209
cases would have grown it 83 lines over. The three detour cases move to
codex-routing-cache-affinity-detour.test.ts byte for byte with their own
minimal harness, registered in both layout.json and the expected fixture.

* fix(codex): bind Cursor and Devin live rosters to the observing credential

The live Cursor and Devin model rosters are entitlement-specific, but their
provider roster cache was scoped by provider name alone: a credential switch
could read the previous account's fresh or stale plan roster, and a failed
discovery's cooldown suppressed the next credential's first fetch while
offering it the previous account's stale list. Bind the cache entry to an
irreversible credential fingerprint (the Qoder precedent), make the stale
fallback credential-scoped, and let a credential with no roster of its own
fetch through another credential's cooldown. Quota and rate-limit health stay
account-scoped by design: they describe the subscription, not the token
generation, and the 401/403 quarantine is already generation-fenced.

* fix(codex): fence cancelled entitlement refreshes behind caller cancellation

A data-plane /v1/models request now passes its own signal into admitted
entitlement resolution, and the native-main token refresh re-checks that
signal after the upstream grant resolves and before the auth.json commit: a
refresh that resolves after its caller went away no longer rewrites the
physical credential on behalf of a request that no longer exists. The reauth
twin already fenced its commit the same way; the roster-cache publication
stays fenced by credential identity and mutation epoch, which is the
correct boundary for a shared flight.

* feat(usage): opt-in privacy-bounded cache diagnostic (#5178)

Under OPENCODEX_CACHE_DEBUG=1 the proxy writes one record per finalized
request to <config-dir>/cache-debug.jsonl (0600, 200-to-100 rolling), letting
an operator compare two requests and tell a client prefix change, an account
change, and a proxy transformation change apart as the cause of a cache-read
drop. Records hold only presence booleans, counts, closed enums, the raw
upstream cache counter before defaulting, and process-local HMAC equality
tags (independent process-random key, never persisted) for the prompt-cache
key, allowlisted session headers, the account log label, and ordered
instruction/tool/message blocks capped at 128 per section with only the
first divergent section/index. No prompt text, tool names, raw identifiers,
or header values are recorded, and no tag survives a process restart, so a
fingerprint can never become a public or durable correlation key. The
request path reaches the module through a process-local registration hook so
responses/core.ts gains no runtime import, and an all-zero usage frame with
a measured cache counter now survives extraction instead of collapsing to
"unreported", which is what keeps a measured zero distinct from an absent
counter downstream. Off by default.

* docs(devlog): record lane D account/cache-generation progress

* fix(usage,tests): close review findings on the diagnostic and the moved admission test

Pre-CI adversarial review found two blocking defects: the carried
entitlement-admission test kept its tests-root import paths after the domain
move (every case failed at load), and the diagnostic's block splitter
aliased an array-valued instructions field, so observation would have
mutated the live request body the adapter was about to serialize. Both are
fixed, the second with a mutation regression test. The all-zero usage
extraction change is reverted: it reclassified spend settlement for
placeholder frames, and the measured-zero versus absent distinction already
rides the provenance enum for every frame that reports tokens.

* fix(catalog,codex): derive the reasoning-rung type and scope discovery cooldown to its credential

Exact-head CI on this branch failed gates, both typecheck-dependent shards and
one Cursor case. Three causes, fixed here.

catalog/effort.ts and catalog/build-entries.ts cast a partially populated
ladder to Array<{ effort?: string }> and push a canonical CODEX_REASONING_LEVELS
rung into it, which also carries description. That was always a type error, but
reasoning-effort.ts -> providers/reasoning-metadata.ts -> providers/key-store.ts
-> the ../config barrel formed an import cycle in which the rung type degraded
and the excess-property check never ran. Carried #5145 breaks that cycle by
design, so the latent error surfaced here first. reasoning-effort.ts now exports
CodexReasoningLevel and the three casts derive Array<Partial<CodexReasoningLevel>>
from it rather than restating a narrower shape. The translator-budget contract
test, which spawns tsc over the project, was downstream of these errors.

The Cursor cooldown case was a real regression from this lane. Scoping only the
roster reads to the credential left the failure cooldown provider-wide, so the
branch had to require a credential-scoped stale entry before honouring it, and a
discovery that fails before caching anything has no stale entry -- reopening the
timeout storm #54 closed. The scope now sits where the observation belongs: a
discovery failure records the credential that observed it and suppresses only
that credential. A failure recorded without an identity stays
credential-agnostic and suppresses everyone, so plain-endpoint providers and the
existing Qoder branch are unchanged.

cache-diagnostic.ts narrowed draft.promptCacheKey through optional chaining and
then read it again unguarded; the inbound key is bound once.

* fix(gui-tests): derive the usage header and locale symbol checks from their sources

The carried #4793 columns broke three GUI assertions that restate what the
page and the catalogs already own.

usage-custom-range listed the models-table headers as English literals and
omitted the API list-price column that ships today, so the case failed on any
tree where both exist. The expectation now maps the ordered column keys the
page renders through the en catalog, which is where that copy lives.

The French accidental-English guard and the zh-TW stale-placeholder guard both
flagged usage.unavailable, whose value is an em dash. A value with no letters
once its placeholders are removed has nothing to translate and is identical in
every locale by construction, so both checks now derive that from the value
instead of taking one more allowlist entry. Real words still fail: the existing
entries that carry letters, such as uptime.hour, remain allowlisted and
required.

* docs(devlog): record the lane D CI dispositions

* test(ci): quarantine the 50 MiB sideband relay case into its own lane

sideband GET /v1/live/{callId} relays a 50 MiB WebSocket frame end to end
against a hard 15s deadline while sharing a process with the rest of its
--shard=N/2 half, so its result measures the whole process rather than the
relay. On dev it lands in shard 1 and its echo leg alone spends 7.4s of that
budget. Three test files added elsewhere in this branch made Bun repartition
the halves, the case moved to shard 2, and the echo leg went past 15s twice
with the peer never receiving the frame -- with nothing on the sideband path
changed.

SERIAL_FULL_SUITE_FILES is the mechanism this repository already has for that
category; its own guard describes it as quarantining load-sensitive files into
one-worker lanes. The deadline, the assertion and the macOS leg are unchanged;
the case simply stops sharing a process, which also keeps it from breaking the
next branch that adds a test file anywhere in the tree.

Superseded by #5268, merged to dev as 53725b0dec3e20f1d6e5d0e144aab4a3ab722806, carried with attribution in the branch commit.

Entitlement credential refreshes are now fenced behind admission, so a cancelled request's late refresh cannot overwrite another request's binding.

The four account-scoped pull requests landed together because they are one attribution defect seen at different layers: an observation belonging to an account or credential generation must not survive its replacement. Fixing them separately would have left each one's tests blind to the others' leakage.

Closing as superseded rather than stale.
