Summary

  • Carry fix(codex): keep native main in Pool health on translated Claude turns #6507 by @vadymhimself (610824401a488515f6e451d7b926b928ee9d005a, 7ffd1a856957c320d139ff262b4adaf4dd3da07b). Stored native-main credentials injected for translated Claude turns participate in Pool refresh and health; genuine caller credentials remain caller-owned, including when their token bytes match stored main.
  • Bind rejected native refresh grants to the physical profile and grant fingerprint. Selection and automatic materialization stop repeating a refused grant; replacement credentials remain usable. Ordinary quarantine clears and successful usage polling do not revive it. State is process-local and bounded to 64 records.
  • Share refresh classification and fixed status/code diagnostics between main and pool. Keep 429/5xx, malformed responses and unknown structured codes transient; preserve description-only OAuth 400 compatibility. Typed causes drive sign-in guidance, and final account projection checks scoped refusal under native ownership. No upstream-body/message logging is added.

Builds on the merged quota/probe correction in #6515. The coordinator owns merges and final integrated regression. This lane does not close either source PR. The shared response-options/combo message-logging hunks from #6507 were deliberately omitted; subsequent spending integration must preserve that boundary.

Verification

  • Focused runtime/contract checks: 904 pass / 0 fail across 18 files, covering native Responses/compact refresh, grant refusal/replacement/cancellation, caller ownership, pool refresh/backoff, auth context/API, hard-lock recovery, quota priming/reporting, blocked redirects, core/Lab isolation, both test-layout registries and the size ratchet.
  • An inherited test worker authored two scoped regression files; Main checked the diff and ran the combined suite. Real caller tests include identical stored/caller token bytes. Tests drive actual WHAM success before reoffering a refused grant.
  • Independent security reviews covered state/classification and provenance/retry/DTO paths. Both PASS after fixing the indirect caller/selection read-fence regression and preserving safe TokenRefreshError.status/code metadata. The fence regression failed twice before the correction; the focused closure run passed 69 tests.
  • bun run typecheck, bun run privacy:scan, bun run structure:check, git diff --check: pass. Docs build passed (561 pages, 77,929 internal links).
  • Full local suite exception: concurrent release worktrees share this host; focused behavior tests were run and applicable per-PR exact-head CI is required. Coordinator owns final integrated lane=all checks.
  • Live provider sessions, packaged native clients and Windows-native credential behavior remain unverified. Tests use isolated synthetic credentials and mocked provider traffic. No installed app or account settings were changed.

Publication head: 06034e44f2802d002e7ff525847782d2133fb161. The late fixed-main guidance and premature success-log findings are corrected. Main usability derives three safe booleans from one physical snapshot after the ownership fences; existing liveness callbacks remain supported. Tests show 30 pass / 8 fail before repair and 38 pass / 0 fail after it, including paused/non-main/caller-owned and valid-response controls. Combined focused verification: 934 pass / 0 fail across 20 files; typecheck/privacy/structure pass. Independent five-file security closure: PASS, including live hard-lock policy precedence. All six earlier and late known corrective review topics are addressed; fresh current-head CI and coordinator narrow closure remain pending, so the PR stays draft. Prior-head CI is not substituted.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Summary by CodeRabbit

  • New Features
    • Added clearer sign-in guidance when a stored main-account refresh grant is rejected. Sign in again with codex login to replace it.
    • Caller-supplied credentials remain separate from stored main-account credentials and are not affected by a stored grant’s rejection.
  • Bug Fixes
    • Stopped retrying a rejected stored refresh grant across requests; rate-limit and server failures remain retryable.
    • Prevented cancelled account transitions from saving refreshed credentials or triggering inference.

📝 Walkthrough

Walkthrough

The change classifies pool and native-main refresh failures, records terminal native-main grant refusals, and reflects those refusals in account selection and sign-in responses. Responses routing also distinguishes caller-supplied credentials from stored native-main credentials. Tests cover refusal, cancellation, replacement, classification, and routing cases.

Changes

Refresh grant handling

Layer / File(s) Summary
Shared refresh failure classification
src/codex/chatgpt-refresh-failure.ts, src/codex/account-store.ts, tests/codex-integration/codex-account-store-refresh-classification.test.ts, structure/providers/openai-accounts.md
Pool refresh failures use a shared classifier and bounded response-body reads. The classifier distinguishes terminal from unknown failures and retains status and allowlisted diagnostic codes. Tests cover transient statuses, malformed responses, and safe logs.
Native-main grant refusal lifecycle
src/codex/main-account.ts, src/codex/account-runtime-state.ts, tests/codex-integration/codex-main-grant-refusal.test.ts, tests/responses/responses-alternate-main-cancellation.test.ts, tests/codex-integration/main-account-hard-lock-recovery.test.ts, scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json, docs-site/src/content/docs/reference/configuration/server.md
Native-main refresh uses the token endpoint and classifies its response. Terminal refusals are recorded by auth-file path and grant fingerprint in a bounded process-local set. Tests cover repeat attempts, grant replacement, profile scoping, cancellation, and selection fences.
Account state and sign-in responses
src/codex/account-usability.ts, src/codex/auth-api/*, src/codex/auth-context.ts, src/codex/routing/selection.ts, src/server/responses/codex-auth-error.ts, tests/codex-integration/codex-account-unusable-reason.test.ts, tests/responses/responses-native-main-refresh.test.ts, structure/providers/openai-accounts.md
Account usability and main-account snapshots include grant-refusal state. Pool-authentication errors carry a quarantinedMain flag, and mapped responses use shared sign-in guidance when that flag is set. Tests cover terminal and transient responses, account listing, and combo fallback.
Credential provenance in Responses routing
src/server/responses/core-auth.ts, src/server/responses/core-codex-account.ts, src/server/responses/request-prepare.ts, tests/responses/responses-native-main-refresh.test.ts, tests/responses/responses-preview-main-read-fence.test.ts, tests/routing/router-blocked-cross-provider.test.ts, structure/providers/openai-accounts.md
Routing determines credential ownership from validated caller Direct credentials and trusted injected native-main credentials. Request preparation and alternate-account selection use that ownership result. Tests cover caller-owned authentication and credential-domain headers.

Merge Risk: 🔵 Low · up to d5ecc

This change alters how rejected Codex refresh grants and credential ownership are handled. Tests cover the main paths, but live provider and Windows behavior and fresh CI are still unconfirmed. Confirm those before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to d5ecc

The change strengthens separation between caller credentials and saved credentials, with safeguards for credential replacement and cancellation. No introduced security defect was established in the inspected flows, but incomplete authentication-lifecycle coverage leaves limited residual risk.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The inspected authority changes affect the stored native-main credential file, its upstream account identity, and shared account-routing state. Refusal isolation follows physical profile path and refresh-grant fingerprint, rather than globally retiring every credential represented by the main account sentinel. Deployment-wide or tenant-wide exposure cannot be established from the supplied topology coverage.

Trust Boundaries and Controls

  • observed — A caller bearer that matches observed main credentials receives policy checks, not stored-main refresh authority. Caller-owned materialization forwards the request credential; asynchronous stored-main refresh requires explicit substitution. Trusted Claude-main injection is separately identified by internal route options and canonical-forward routing.
  • observed — Account usability checks hard-lock and legacy-sentinel controls before the ownership-specific branches. Inspected authentication callers derive selection-only behavior from profile-drain state and prevent request-owned credentials from inspecting physical main state. Thus, bypassing stored refusal for a caller credential does not itself bypass the inspected ownership controls.

Resilience and Maintainability Implications

  • observed — Ordinary reauthentication clearing is separate from scoped grant refusal. Replacing a grant changes its refusal key, while a stale terminal response must pass snapshot and cancellation checks before recording refusal. This limits an old failed refresh from contaminating replacement credentials.

Owner Author

Owner-authorized progressive maintainer integration into dev for release stabilization; this is a scoped integration/security decision, not a self-approval.

Independent coordinator review covered the original22files, the nine-file cancellation/read-fence repair, the five-file guidance/logging/snapshot repair, and the final additive hard-lock spy at this exact head. R1 was reproduced and fixed without waiver: alternate credential resolution now carries caller cancellation, owner guards prevent late credential/refusal mutation, and the existing account-move permit cleanup refunds before any physical retry. Known review findings are resolved.

Trusted stored-main enrichment participates in native Pool health; real caller credentials retain request ownership even when bytes match stored main. Routing markers are not authentication proof. Refusal state is keyed to the actual physical profile and hashed refresh grant, process-local and bounded to64records; restart/eviction can recheck and no stronger persistence guarantee is claimed. New/replaced credentials retain their own eligibility. Ordinary quarantine clear and WHAM success do not revive a retained refused-grant record.

I reviewed the coherent state view, exact-main sign-in cause, and parse-before-success diagnostic. Hard-lock, selection-only/request-owned read fences and model policy checks remain ahead of physical access. The status view exports booleans, not credential material; malformed2xx responses receive only a fixed transient diagnostic. Structured400/401/403 terminal classification, unknown/429/5xx transience and documented description-only400 compatibility remain distinct. Explicit security review: no remaining blocker in these boundaries.

Focused red/green/consumer checks and type/privacy/structure/docs gates passed; the final one-line spy strengthens existing hard-lock proof without runtime change. No live provider/native-client/Windows credential behavior is implied. Current dev's other accepted integrations have been assessed for overlap; the prospective union passes actual line caps and test-map parity. Final independent integrated regression and full cross-platform CI remain required before publication. Source6507 credit is retained; any deliberately uncarried logging-only scope will be reconciled separately rather than silently closed.

Hosted receipt: https://github.com/lidge-jun/opencodex/actions/runs/37145111209, attempt 1, pull_request, tested head d5eccb7c58843aba5d903f2f1aed1ae68fcf3814 / base a99de42e7a5986c2443805fa6d833b8152f967ff.

All four Linux shards and selected gates/storage/API/docs/structure/Docker/keyring/npm-global jobs succeeded.
