fix(codex): keep native main in Pool health on translated Claude turns - #6507
vadymhimself wants to merge 2 commits into
Conversation
A Claude Code turn routed through a combo whose first leg is the canonical ChatGPT forward provider sent a revoked credential upstream on every single request, indefinitely, and reported it as a provider error. The Claude Messages ingress attaches the stored ~/.codex credential to a translated turn so forward sidecars stay reachable, and `codexRouteCredentialDomainHeaders` puts it on the headers the Codex auth resolution reads. `hasForwardableCodexBearer` then sees a Codex JWT carrying an account id and cannot tell our credential from one the client supplied, so `requestScopedMainCredential` came back true and the native main slot resolved as a caller-owned `main` context instead of `main-pool`. Caller-owned credentials deliberately own no Pool state, so the upstream 401 recorded no outcome, attempted no refresh, retired nothing, and the next request sent the same dead token again. The ingress already states the rule it needs here -- it passes `nativeCallerAuth` and `callerDirectAuth` as null because its stored-main enrichment is not an original caller credential -- so ownership is now decided by provenance where both the resolution and the lineage preview read it, and they cannot disagree. A bearer the client really did supply sets no enrichment and stays caller-owned. With the slot back in Pool health, the rest of the path had to work: - A refresh refusal is classified from the token endpoint's structured `error` code alone, by one rule now shared with the stored-pool refresh, so one dead grant cannot be terminal for a Pool account and transient for main. The native-main classifier searched its own formatted message, which missed `refresh_token_reused` and read a 5xx's "session expired" prose as proof. - A code-confirmed refusal marks the account AND retires the grant by fingerprint, because a present refresh grant otherwise cancels the quarantine it just earned. The verdict survives a reauth clear -- the WHAM probe retracts quarantines on an explicit refresh, which an open dashboard triggers -- and is retracted only by a successful refresh or a replacement credential. - The refusal says what happened and what fixes it, on the request that discovers it and on every request after, instead of "needs reauthentication" once and "no usable account credential" forever. - Each refresh verdict logs once with the endpoint status and code and no credential material. This is what identified the live fault. - The combo failure warning is one line again: it preferred the whole error envelope, so a single 401 printed a multi-line JSON body across the log.

Merge Risk: 🔵 Low · up to In a narrow Pool configuration, users may be told to sign in when they must also unpause the main account; operators also lack required details for diagnosing pool refresh refusals. These are bounded issues, so the PR is mergeable with owner awareness and follow-up. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The change improves separation of caller-supplied and locally stored credentials and prevents repeated use of rejected refresh grants. A credential replacement can still leave restricted requests blocked until recovery state is cleared. No new privilege escalation was established, but coverage remains incomplete. Retained concerns

for each subsequent call to `handleClaudeMessages` instead of reusing the
released `comboTurn`. Acquire and verify a new lease before each call, pass it
in that request’s context, and release it after consuming the response so the

- Keep the sign-in refusal in the response layer, so the change no longer touches src/codex/auth-context.ts. - A non-string error_description falls back to the HTTP status instead of throwing a TypeError out of the refusal classifier. - The combo test takes a fresh turn lease per request; with dead-grant retirement disabled, it now fails.

Carry the quarantine reason on CodexPoolAuthenticationError.
An empty codexAccounts list alone does not demonstrate this issue: Pool routing also considers __main__. But when __main__ is paused and marked for reauthentication, the pause independently excludes the only candidate. For a normal, ungated Pool request, the no-candidate branch throws the default error, and the mapper reports sign-in-required from the separate reauth flag. While the pause remains set, signing in alone does not restore a candidate. Set a typed quarantinedMain marker at the throw site only when reauthentication caused the refusal, and have the mapper use that marker.

Summary
A Claude Code turn routed through a combo whose first leg is the canonical ChatGPT forward provider sent a revoked credential upstream on every request, indefinitely, and surfaced it as a provider error.
The Claude Messages ingress attaches the stored
~/.codexcredential to a translated turn so forward sidecars stay reachable, andcodexRouteCredentialDomainHeadersputs it on the headers the Codex auth resolution reads.hasForwardableCodexBearerthen sees a Codex JWT carrying an account id and cannot tell our credential from one the client supplied, sorequestScopedMainCredentialcame back true and the native main slot resolved as a caller-ownedmaincontext instead ofmain-pool. Caller-owned credentials deliberately own no Pool state, so the upstream 401 recorded no outcome, attempted no refresh, retired nothing, and the next request sent the same dead token again. The ingress already states the rule it needs here — it passesnativeCallerAuthandcallerDirectAuthas null because its stored-main enrichment is not an original caller credential — so ownership is now decided by provenance at the one place both the resolution and the lineage preview read it, and the two cannot disagree. A bearer the client really did supply sets no enrichment and stays caller-owned, exempt from stored state as before.With the slot back in Pool health, the rest of the path had to work:
errorcode alone, by one rule now shared with the stored-pool refresh, so one dead grant cannot be terminal for a Pool account and transient for main. The native-main classifier searched its own formatted message, which missedrefresh_token_reusedentirely and read a 5xx's "session expired" prose as proof of a dead grant.Two notes for review. The live confirmation came from a path whose refresh succeeded, so the retire-on-refusal half is covered by tests rather than by production evidence. And
main-account.tsnow posts its own refresh rather than callingrefreshChatGPTToken, in order to see the structured error code without touchingsrc/oauth/; a reviewer may legitimately prefer that the error type move intosrc/oauth/chatgpt.tsinstead, which is the smaller diff if the hygiene gate is not a concern.Verification
Live, on the affected host:
[codex] 401 upstream without native-main refresh: kind=main forwardableBearer=n callerBearer=n admission=loopback pinned=none forwardPoolAuth=n adapter=openai-responses authMode=forward accountMode=pool,~/.codex/auth.jsonuntouched,needsReauthnever set, and the raw upstreamtoken_invalidatedtext repeated on every request. (That probe line was diagnostic scaffolding and is not part of this PR.)[codex] native main refresh: ok status=200 code=none— OpenAI accepted the refresh grant after the plan-change revocation,auth.jsonwas rewritten, and the account recovered as planfreewithneedsReauthfalse. The revoked session self-heals through its refresh grant once the path is actually reached.Commands run:
bun run typecheckbun scripts/file-size-ratchet.tsbun run structure:checkbun run privacy:scanbun test tests/test-layout.test.tsbun test tests/responses tests/codex-integration tests/claude-integration tests/server tests/routing tests/test-layout.test.ts, run on this branch and on a pristineupstream/devworktree at the same base: 94 failures on both, byte-identical failure sets, all pre-existing. Pass count 16934 → 16941, the difference being the tests added here.Red/green on the behavioural change: removing the single ownership condition in
codexRouteCredentialOwnershipreproduces the production signature exactly —[combo] codexfirst: openai/gpt-5.5 failed with 401 ...: token_invalidated: Your authentication token has been invalidated.— and the test fails. Restored, the leg fails over locally in 1 ms with the actionable refusal and never reaches upstream. Each of the other changes was likewise proven red by reverting its own file.Not run: the full
