Preserve denial evidence for main-pool accounts.
usesCodexForwardPoolAuth admits both "pool" and "main-pool". In preparePassthroughExchange and retryCodexPoolOnAlternateAccount, the denial recorder receives undefined for a "main-pool" context because only "pool" supplies generation. The guard at line 1353 then discards the allow-listed 400. Before this change, the wrapper accepted no generation and stored the evidence, so cache-only routing could avoid selecting that account again.
The success path has the same issue: it passes undefined to clearCodexModelDenialEvidence, so an account-scoped main-pool entry could not be cleared. Use a discriminated evidence scope for generation-scoped pool evidence and account-scoped main-pool evidence. Apply generationIsLive only to generation-scoped entries. Add regression coverage for recording and clearing evidence through both main-pool response paths.

An authenticated unsupported-model refusal is remembered for six hours under (account id, model id) with no credential generation. Re-auth of the same pool account keeps the internal id and increments the generation, and can swap the subscription underneath it — so the previous credential's refusal keeps steering routing away from an account that now has access. The account-wide forget that would have covered this (`model-entitlements.ts`) sits behind a condition requiring a previously cached roster with changed identity, so with no roster it never runs — which is exactly the state the flagship request path is usually in, since nothing on it refills the five-minute roster cache. Entries now carry the generation they were observed under, and: - the reader drops evidence whose generation is no longer live, so superseded evidence stops influencing the replacement without depending on the conditional forget; - a write from an older generation cannot overwrite newer evidence, so an in-flight generation-G refusal landing after G+1 is saved neither resurrects nor rewrites it; - a clear from an older generation cannot delete newer evidence, so a late generation-G success cannot re-admit an account the current credential has just been refused by. An equal generation still clears: that is the ordinary "this account just served this model" case. Evidence that cannot name a generation is dropped rather than attributed to whatever is current. Main-account contexts carry no pool generation, and already carry no account id, so nothing changes there. Cache-only routing, the six-hour TTL, the entry bound, positive-roster precedence and empty-filter restoration are all untouched. The liveness predicate is injected rather than imported so the store stays a leaf module; production wires `isCodexAccountGenerationLive`. Closes lidge-jun#4952

…ore they evict Three defects in the carried #5092, found by adversarial review of the generation fences rather than by CI, which was green on all three. 1. main-pool evidence was silently discarded. Both production call sites pass `kind === "pool" ? generation : undefined`, and the carried code dropped any refusal that could not name a generation. A `main-pool` context - the stored main login taking part in rotation - has a real accountId and no POOL credential generation, because its credential lives in auth.json. So for that account #4906 reverted: the pool would re-send the model the login had just refused, on every request. A refusal with no generation is now ACCOUNT-scoped and the generation fences do not apply to it. This is the rule core-codex-account.ts already uses for the quota writer, where an absent credential generation skips the liveness check instead of discarding the write. Request-owned `main` is unaffected: its accountId is null and the existing guard returns before any of this. 2. The stale-write fence only rejected a late refusal when the same key already held newer evidence. With no entry for its own key the stale row was inserted, and at the 512-entry bound that insert evicts the oldest valid row - which no later read fence can restore, because the evidence is gone. The write now rejects a generation that is no longer live before touching the map at all, which closes the race the issue names rather than only its common case. 3. The read fence validated liveness for every non-expired entry before checking the model or the caller's exclusion set, and DELETED any row that came back not-live. Two problems. The issue asks for validation after the exclusion read fence, and an excluded account - a draining profile switch, or a request-owned credential - was causing a credential-store read on its behalf. And the predicate cannot tell "this account reauthenticated" from "the store could not be read": loadCodexAccountRecordStore catches a read failure and returns {}, so an unreadable store deleted valid evidence permanently. The reader now matches the model and applies the exclusion set first, and SKIPS a non-live row instead of deleting it. Skipping already produces the routing outcome on every read; deletion only saved memory in a bounded map, and it was the part that was unsafe. Superseded rows still leave by TTL, by eviction, and by the account-wide forget. Each liveness check also reloaded and reparsed the whole credential store per row, on the request path. The seam is now a factory that opens once per lookup over one loadCodexAccountRecordSnapshot, which is the shape that snapshot was added for, and it is not opened at all when no matching row carries a generation. Every constraint the issue sets is unchanged: cache-only routing with no added upstream fetch, the six-hour TTL, the 512-entry bound, positive-roster precedence, and empty-filter restoration. This remains an ordering preference, not an eligibility filter, and a live-generation refusal still denies. Co-authored-by: Abhishek Sharma <abhicse24@gmail.com>
…ice (#5199) * fix(codex): preserve pool reauthentication failure causes PoolQuotaResult now carries the failure source observed while obtaining WHAM/quota or refreshing tokens, so poolAccountDto reports the actual cause instead of inferring it from overlapping booleans. Terminal WHAM 401s surface as quota_unauthorized and terminal refresh failures as refresh_failed. Carried from #5191. The two regression cases are registered from tests/helpers/pool-reauth-cause.ts rather than written inline: the original placement grew tests/codex-integration/codex-auth-api.test.ts from 6522 to 6560 lines against a 6549-line file-size-baseline cap that only ever moves downward. Registering them through the same registerXCases seam the file already uses for two other helpers leaves it at 6525 with the assertions byte-identical. Co-authored-by: luvs01 <27862058+luvs01@users.noreply.github.com> * fix(server): stop a local catalog-sync warning from un-readying the proxy /readyz went to a terminal failed state on any nonempty warning from the post-startup Codex sync. A warning there describes artifacts written into the LOCAL Codex home, not the proxy's ability to serve: no catalog source so Codex keeps its native catalog, combos omitted from the catalog, a conversation-history relabel left to Codex's own writer, or a caught catalog-refresh exception after which config injection still runs and still reports its own ok. The sync continues past every one of them. #5181 is what that cost. A single-replica Kubernetes deployment lost its only Service endpoint while every non-Codex route stayed healthy, because the readiness probe read a degradation of a local file as a dead process. Switching the probe to /healthz restored service, which is the reporter's own evidence that the process was viable. ok and warning are separate fields in the sync result because they answer separate questions. ok is the sync's verdict on the essential work - the write admission and the config injection. The gate now follows ok alone. The narrowing is only to warning. A throw, a null outcome, and ok !== true stay terminal, so the service-home write refusal, the external-provider injection failure, the config/integrity preflight refusal and the final injection failure all still fail readiness. A throw and a null stay terminal for a different reason: neither is a classified outcome, so the gate cannot claim one. Readiness also still stays pending until the sync SETTLES, which is the race the gate was built for and which this does not touch. This is the boundary the Claude Code roster reconciliation already has - it delays the ready transition without being allowed to fail it - applied to the catalog sync. Scope note: the brief for this work held that the Codex pool's "needs reauthentication" warning was itself the terminal warning. It is not. That line comes from warnGatedNativeSuppressedOnce (src/codex/catalog/gated-native-warn.ts) and is a bare console.warn that never enters the structured result, and per-account pool refresh failures are caught and returned as null by model-entitlements.ts rather than propagating. The account-level fault that does reach the gate is a native MAIN credential refresh failing outside that per-account catch: it rejects the entitlement gather, surfaces as the catch-all "catalog sync skipped" warning, and permanently un-readies the process. That is the same class of blast radius the report describes, and it is closed here.

Closes #4952, following the fix direction in the issue.
The bug
A refusal is remembered for six hours under
(accountId, modelId)with no credential generation. Re-authenticating the same pool account keeps the internal id and increments the generation — and can swap the subscription underneath it — so the old credential's refusal keeps steering routing away from an account that now has access.The account-wide forget that would have covered this is conditional:
With no roster cached it cannot run — and that is the usual state on the flagship path, because nothing there refills the five-minute roster cache. So the one cleanup that existed is unavailable in exactly the situation the issue describes.
The fix
Entries carry the generation they were observed under, and three fences use it:
The read fence is what makes this self-healing: it does not depend on the conditional forget firing.
Both races the issue names are covered. A generation-G refusal arriving after G+1 is saved neither resurrects nor rewrites G+1's entry; a generation-G success arriving after G+1 was refused cannot re-admit an account the current credential has just been refused by. Equal-generation clears still work, because that is the ordinary "this account just served this model" case.
Evidence that cannot name a generation is dropped rather than attributed to whatever is current. Main-account contexts carry no pool generation — and already carry no account id — so nothing changes for them.
Constraints kept
Cache-only routing (no added upstream fetch), the six-hour TTL, the 512-entry bound, positive-roster precedence, and empty-filter restoration are all untouched. This remains an ordering preference, not an eligibility filter.
The liveness predicate is injected rather than imported, so
observed-model-denialsstays a leaf module — a unit test of the map shouldn't have to stand up the credential file. Production wiresisCodexAccountGenerationLive, which already answers exactly this question for the account store.Verification
16 pass / 0 failoncodex-model-denial-evidence.test.ts— the 10 existing tests updated for the new signature, plus 6 for the generation behaviour: superseded evidence stops denying, a late refusal cannot deny the replacement, a late refusal cannot overwrite newer evidence, a late success cannot clear newer evidence, a same-generation success still clears, and a generation-less record is dropped.Mutation-tested, 5/5 killed: remove the read liveness check; remove the write fence; remove the clear fence; make the clear fence
>=(too strict, breaks the ordinary case); accept an undefined generation.Wider run:
5961 pass / 11 failacross the 253 codex/entitlement/passthrough suites. The same 11 fail identically ondev(5955 pass / 11 fail) — verified by stashing, so this adds 6 passing tests and no new failures.bun x tsc --noEmitleaves the 2 pre-existing errors ondev(claude-messages.ts:611,fetch-helpers.ts:277) and adds none.privacy:scanpasses.Note
The issue was filed from a static source audit rather than a live reproduction, and I have not reproduced it live either — re-auth against a real pool account isn't something I can stage here. What I can say is that the control-flow reasoning holds on the current tree and the fences are pinned by tests that fail without them.
