Summary

After a restart, a persisted main-account 99% quota snapshot can remain hidden because its process-local identity and credential binding have not been rebuilt. A caller-owned Direct request then reaches upstream even after owned startup reports ready.

Restore the binding from the pinned native auth path under the native owner and exclusive claim, after recovery and stage cleanup and before publishing ready. The same transition handles successful cleanup retries, explicit recovery, and another listener using the existing lifecycle. Duplicate completion joins an active startup, and older sweep results cannot overwrite its gate.

Caller-owned Direct, main fallback, and main-pin selection briefly return the existing 503 maintenance response while this initialization is active. Healthy stored Pool alternatives remain eligible. Foreign/unknown service homes introduce no credential read or ownership reprobe through caller-owned admission. With protection disabled, the additional credential read and claim are skipped. Malformed fields or conflicting identity claims create no new binding and do not become recovery exceptions. A previously verified same-process binding and its safety state remain until a valid replacement observation or confirmed account transition; rejected input alone cannot release a measured block.

The binding remains memory-only; no credential equality tag is persisted. English/Korean account references and the account-policy invariant document the startup behavior.

The initializer extracts the ID-token and access-token account identities separately and checks each present identity against the owned file's explicit account ID before changing observations. This prevents an ID token for A from masking an access token for B. Owned opaque bearers retain the existing explicit-account fallback; JWT decoding is not the source of ownership or credential authentication.

Verification

  • Head 6c1387dc460c456a17f8808607ca4cb9fcd5cbfc, based on dev 29bb221c3cfad89e4920ac411c9681073929c152; Bun 1.4.0 on Windows.
  • Isolated baseline: a fresh process started the real server with an owned synthetic home and a seven-hour-old, identity-tagged 99% quota file. The auth resolver admitted main before and after startup settled, and the real Responses handler returned 200 with one mocked upstream send. The fix returns the startup fence before binding and 429 with zero upstream sends after binding. The 98%, foreign, and unknown controls preserve their expected behavior. All network calls are mocked or rejected; no real credentials or services are used.
  • Final validation across auth context, hard-lock auth/policy/recovery, quota provenance, native startup, and native-profile API: 230 tests / 1,174 assertions passed, 256.25 seconds. Run with bun run test -- --timeout 60000 --parallel=1 and those seven files. Final typecheck, privacy scan, and diff check passed.
  • Seventeen fresh-process scenarios cover persisted quota, first admission, foreign/unknown ownership, held recovery and credential replacement, caller fallback/main pin versus automatic Pool selection, another listener, malformed token fields, cleanup retry, explicit recovery completion joining, a stale sweep result delivered during rebinding, retention across rejected same-process reinitialization, cross-token identity conflicts, and opaque-token compatibility. The retention scenario checks malformed, explicit-account-conflicting, and cross-token-conflicting inputs keep A's verified 99% block while B remains allowed, then a valid B observation invalidates A and clears A's quota evidence.
  • Negative controls failed when startup binding, the caller pending fence, late-recovery rebinding, stale-sweep fencing, or optional-token validation was deliberately removed. Production source was restored and hashes checked after each control.
  • Typecheck, privacy scan and git diff --check passed. Documentation build passed: 425 pages; the English/Korean rendered startup and 503 text was checked.
  • The initial runtime implementation at 9e632f6 passed all 26 contributor CI jobs. Retention follow-up 3edfb45 changed only tests, an initializer comment, and the policy invariant. Deliberately clearing the binding on a malformed owned read made the new retention test fail because A lost its verified match while its 99% quota remained. Source was restored afterward.
  • CodeRabbit withdrew the retention P1. Its separate cross-token identity finding reproduced on 3edfb45: a fresh conflicting credential incorrectly matched A, and a conflicting rearm released the prior A caller to upstream. The independent token checks fix both cases; an opaque owned bearer remains supported. CodeRabbit reassessed 6c1387dc4 and resolved both inline findings; actual review-thread resolution was verified. Current-head full contributor CI passed all 26 jobs. Maintainer sponsorship and explicit maintainer security review remain pending, so this stays a draft.

Review Change StackReview Change Stack

📝 Walkthrough

Walkthrough

The change restores the main-account policy binding during owned startup, tracks pending initialization, fences caller-owned main credential routes, rearms binding after recovery or listener changes, documents the behavior, and adds multi-scenario integration coverage.

Changes

Main-account policy binding

Layer / File(s) Summary
Pinned auth binding initialization
src/codex/account-lifecycle.ts, src/codex/auth-collision.ts
Reads tokens from the pinned auth path, validates account identity, updates observed identity state, and records the main quota credential.
Owned startup convergence and rearming
src/codex/native-profile-startup.ts, docs-site/src/content/docs/reference/cli/providers-accounts.md, docs-site/src/content/docs/ko/reference/cli/providers-accounts.md
Tracks pending binding, initializes it after recovery and stage cleanup, defers sweeps, and rearms existing lifecycles after recovery or listener startup. Documentation describes the startup and admission behavior.
Pending binding admission fencing
src/codex/auth-context.ts, structure/08_openai-provider-tiers.md
Rejects caller-owned main credential routes while binding is pending. Documents eligible Pool alternatives and foreign or unverified home behavior.
Scenario coverage and startup fixtures
tests/codex-integration/main-account-hard-lock-auth.test.ts, tests/helpers/main-account-policy-startup-child.ts
Tests owned recovery, invalid identities, listener rearming, stage retries, manual recovery, stale sweeps, admission, and response handling.

Priority: ⬆️ High — Prioritize this broad startup and credential-admission change because failed auth verification can leave a stale binding that lets caller-owned requests inherit the main-account policy.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to 9e632

Invalid replacement credentials can leave an old main-account binding active, and conflicting token identities can bind the wrong bearer to an account. These authorization defects should be fixed before merge.

@coderabbitai review

Please review head 9e632f6450bfdeb3a98bda0c94124ee22c44d5ef against 29bb221c3cfad89e4920ac411c9681073929c152, including credential ownership and admission safety.

The startup/recovery lifecycle rebuilds the process-local main-policy binding only from its pinned auth path under the held owner and exclusive claim, before ready. The shared rearm handles another listener, safe stage retry and manual recovery; active work is joined, and stale sweep results cannot overwrite a newer gate. The caller-owned Direct/fallback/main-pin fence has no physical read or ownership reprobe, and healthy stored Pool selection remains available. Invalid credential fields stay unverified. Protection-off startup skips the extra auth read and claim.

Fourteen fresh-process cases and the related suites passed: 227 tests / 1,111 assertions across seven files. Removing the binding, pending fence, late-recovery rearm, stale-sweep guards or optional-token validation made the corresponding negative control fail; all source was restored. Typecheck, privacy scan, diff check, and the 425-page documentation build passed. Independent read-only correctness/security review found no remaining required corrections.

Full contributor CI: https://github.com/luvs01/opencodex/actions/runs/34226189307. Maintainer security review and the applicable sponsorship/readiness gates remain pending.

@luvs01 I found one admission-safety issue.

P1 — Clear the prior credential binding when owned rebinding cannot verify auth.json.

initializeMainAccountPolicyBinding() returns false at src/codex/account-lifecycle.ts Lines 84-91 for an unreadable, malformed, or identity-conflicting pinned credential. It does not clear the existing credential HMAC binding. src/codex/native-profile-startup.ts Line 240 ignores that result and publishes ready at Line 243.

This is unsafe after a same-process rearm. For example:

  1. A valid owned startup binds account A and bearer A.
  2. A new listener or recovery rearm starts.
  3. The pinned auth.json is replaced with malformed fields.
  4. The initializer returns false, but the old HMAC binding remains live in src/codex/main-account-cache.ts.
  5. A caller-owned Direct request with bearer A and account A still passes callerMatchesObservedMain() in src/codex/auth-context.ts Lines 449-455.
  6. The request inherits the persisted 99% policy for a credential that the current owned read could not verify.

This conflicts with the stated invariant that malformed credential fields remain unverified and do not inherit main policy.

Clear the process-local credential binding on every failed owned initialization. clearMainAccountInfoCache() already invalidates mainQuotaCredential and advances its generation in src/codex/main-account-cache.ts Lines 100-105. Keep the identity and persisted quota data if required, but remove the HMAC equality evidence before returning false.

Add a regression test that performs a valid startup binding first, replaces the pinned auth.json with each malformed or conflicting variant, rearms through a second listener or recovery completion, and verifies that the old caller bearer receives normal caller-owned behavior instead of CodexMainAccountHardLockError.

리뷰 · 우선순위 66 / 80

이 PR은 Codex 메인 계정 99% 하드락이 재시작 뒤에 풀려 보이는 구멍을 막는다. 지금 dev HEAD는 29bb221c3(2.49.0, 직전에 #4021로 2.48.0 릴리스 기록만 아카이브한 상태)이다. 하드락 정책 자체와 쿼타 캐시 파일(codex-quota-cache.jsonmainPolicyQuota)은 디스크에 남는데, 프로세스 메모리에만 있는 “이 토큰/계정 ID가 메인이다” 바인딩은 재시작과 함께 사라진다. 그래서 소유(owned) 스타트업이 ready라고 말해도, 호출자 소유 Direct 요청이 업스트림까지 새어 나갈 수 있다. 작성자 재현도 그걸 말한다. 7시간 된 99% 스냅샷 + 합성 owned 홈에서, 수정 전에는 바인딩 전에 200/업스트림 1회가 나가고, 수정 후에는 바인딩 전 503 펜스 → 바인딩 후 429(업스트림 0)가 된다.

고치는 위치는 네 겹이다. src/codex/account-lifecycle.tsinitializeMainAccountPolicyBinding(authPath)를 추가해, 핀된 auth.json만 읽고 account_idextractAccountId(...)가 같을 때만 observeMainQuotaIdentity / observeMainQuotaCredential를 다시 건다. src/codex/auth-collision.tsreadCodexTokensResult는 이제 핀 경로를 받을 수 있다(기본은 예전처럼 ambient home). src/codex/native-profile-startup.tspolicyBindingPending을 두고, recovery·stage cleanup이 끝난 exclusive claim 안에서 바인딩을 하고 ready를 올린다. 스윕이 그 창을 덮어쓰지 못하게 epoch/pending 가드도 넣었다. src/codex/auth-context.ts는 바인딩이 끝나기 전에 caller-owned main pin / main fallback을 CodexMainProfileDrainingError(기존 503 유지보수 응답)로 막는다. Pool에 남아 있는 건강한 대안은 그대로 쓸 수 있게 둔다. foreign/unknown 홈은 자격증명을 읽지 않는다. 문서(EN/KO providers-accounts, structure/08_openai-provider-tiers.md)와 14개 fresh-process 시나리오 테스트까지 붙어 있어, “재시작 후 99%가 안 먹는다” 축만 보면 방향이 맞다.

점수 66인 이유. 하드락 사용자에게는 실제 보안/쿼타 구멍이고, 지금 tip 스택(#4002 근처 제품 작업)과 겹치지 않는 독립 버그 수정이다. 다만 아직 draft이고, 게이트가 unsponsored_surface로 hygiene·enforce-target을 둘 다 막았다(intake: hygiene-blocked). 체크리스트도 CI/CodeRabbit/ready가 비어 있다. 즉 내용 점수는 높지만 지금 바로 머지 후보가 아니다. CodeRabbit이 지적한 “잘못된/충돌 자격증명이면 예전 바인딩이 남을 수 있다”도 코드상 열려 있다. initializeMainAccountPolicyBindingstatus !== "ok"이거나 accountId 불일치면 false만 반환하고, 이전에 메모리에 있던 observation을 지우지 않는다. 보호를 끈 경로·미검증 경로 테스트는 있지만, “예전 바인딩이 남아 ready로 새어 나간다”를 명시적으로 깨는 실패 케이스는 PR 본문만으로는 안 보인다.

라인 / 경로로 보면 문제·확인할 지점은 이렇다.

src/codex/account-lifecycle.ts initializeMainAccountPolicyBinding - 토큰 읽기 실패·accountId 불일치 시 false만 돌리고 기존 memory binding을 purge하지 않는다. 잘못된 교체 자격증명이면 옛 정책이 남을 수 있다
src/codex/native-profile-startup.ts convergeOwnedStartup 하드락 분기 - loadConfig().codexMainAccountHardLock === true를 바깥 if와 안쪽 if에서 두 번 검사한다. 동작은 같으나 읽기 비용·혼동만 늘린다
src/codex/auth-context.ts resolveCodexAuthContext - pending 중 caller-owned pin/fallback만 503으로 막는다. “요청 헤더가 메인과 같다” 판정이 바인딩 전후에 어긋나면 짧은 창에서 허용/거절이 흔들릴 수 있다(테스트가 이 창을 얼마나 고정했는지 확인 필요)
hygiene / enforce-target - unsponsored_surface로 blocked. draft 유지·스폰서십 전까지 머지 트레인에 넣으면 안 된다
tests/helpers/main-account-policy-startup-child.ts - 263줄짜리 자식 픽스처가 크다. 시나리오 매트릭스는 좋지만, CI 예산·윈도우 flaky 여부를 한 번 더 봐야 한다

메인테이너의 판단이 필요한 지점

  • 이 표면을 스폰서할지, draft로 두고 기여자 CI·보안 리뷰를 더 받을지
  • 바인딩 실패 시 옛 observation을 purge할지, 아니면 “unverifiable이면 바인딩 없음 + Direct 허용”(현재 테스트 기대)을 유지할지
  • HMAC/credential equality를 계속 memory-only로 둘지(PR 의도), 아니면 재시작 생존을 디스크 쪽으로 옮길 별도 설계가 있는지
  • 2.49 tip(fix(codex): reconcile manual reset cooldowns with owned fresh usage #4002 등)과 병렬로 받을지, 하드락 회귀만 따로 작은 패치로 자를지

너의 추천
내용 방향은 유지하되, 지금은 Ready로 올리지 마세요. 먼저 unsponsored_surface/스폰서십을 정리하고, initializeMainAccountPolicyBinding 실패 경로에서 이전 memory binding을 어떻게 할지(purge vs leave)를 테스트로 못 박은 뒤, draft 해제·체크리스트·전체 CI를 통과시키세요. 그 전엔 머지하지 않는 게 맞다. types/config 분할과 충돌하는 PR은 아니다.

@coderabbitai review

Please reassess the P1 against follow-up head 3edfb452d80325f6903c553ef1446e113dd82288 (base 29bb221c3cfad89e4920ac411c9681073929c152). I corrected the overly broad description and added a same-process regression; I have kept the existing retention behavior.

The current baseline explicitly treats missing/malformed auth as unknown and retains the previous observation and safety state: account-lifecycle.ts. The policy invariant matches callers against credentials and workspaces already observed under ownership and invalidates old evidence on a confirmed transition. A failed read establishes neither a replacement credential nor a confirmed transition. Keeping A's measured block on the exact previously verified A bearer/workspace does not attribute B to A.

The intended distinction is: failed initialization creates no new binding; a previously verified same-process binding and its safety state remain until a valid replacement observation or confirmed account transition. Fresh unbound malformed/conflicting cases still create no binding. The initializer comment, policy invariant, and PR body now say this explicitly.

The new fresh-process scenario first binds A with persisted 99% quota, then rearms through second listeners with malformed JSON and conflicting B-bearer/A-account claims. Both preserve A's match and 429 block, and unrelated B remains allowed. A subsequent valid B observation removes A's match, binds B, clears A's quota evidence, and permits the old A caller normally. The test also accounts for all mocked upstream sends before its primary request.

As a negative control, adding the proposed clearMainAccountInfoCache() to the malformed-read failure path made this regression fail: A's credential match disappeared while its retained quota was still 99%. This would release the matched-caller block without a lower quota observation or confirmed account transition. The temporary change was restored; the follow-up has no runtime logic change.

The initial runtime head 9e632f6 passed all 26 contributor CI jobs. Follow-up hard-lock auth/provenance validation passed 52 tests / 372 assertions; after tightening the call counter, all 15 fresh-process cases / 218 assertions passed again. Final typecheck, privacy scan, and diff check passed. The new head's full CI and maintainer security review remain pending.

Please withdraw the P1 if this clarified existing contract resolves it, or identify a separate demonstrated ownership/admission violation. A change to the retention policy would need an explicit maintainer decision; I have not silently introduced that policy change.

@luvs01 I withdraw the P1.

The prior finding assumed that a failed owned read must revoke the previous verified credential binding. The baseline contract does not use that policy.

In base src/codex/account-lifecycle.ts, Lines 62-75 define a missing or malformed auth.json as an unknown identity. The function retains the prior observation and safety state until it reads a real account identity. It purges state only after a confirmed transition.

The follow-up keeps this behavior. initializeMainAccountPolicyBinding() at src/codex/account-lifecycle.ts Lines 80-98 now documents the same contract. The follow-up changes no runtime retention logic.

The retained binding is sufficiently narrow for this contract:

  • callerMatchesObservedMain() at src/codex/auth-context.ts Lines 449-455 does not read auth.json.
  • matchesMainQuotaCredential() requires the exact process-local bearer HMAC, the effective account identity key, and a live writer.
  • A conflicting B bearer with A as account_id cannot establish B as main because initialization rejects the identity conflict.
  • A valid owned B observation supersedes A. observeMainQuotaIdentity() invalidates the credential binding, and the lifecycle purge removes A policy evidence on the confirmed identity transition.

The lifecycle also keeps caller-owned admission fenced until owned initialization completes. See src/codex/native-profile-startup.ts Lines 227-245 and src/codex/auth-context.ts Lines 607-624.

The new retained-unknown-binding regression covers the required distinction. It verifies that malformed and conflicting rearm data retain the previously verified A block, do not block unrelated B, and that a later valid B replacement removes A matching and clears the retained A policy. This is consistent with the pre-existing provenance test in tests/codex-integration/main-quota-provenance.test.ts Lines 386-400.

I found no separate demonstrated credential-ownership or caller-owned admission violation in this reassessment. I did not execute the test suite in this environment.

Learning: In the Codex main-account policy, a missing, malformed, or identity-conflicting owned `auth.json` read is an unknown identity. `src/codex/account-lifecycle.ts` must retain a previously verified same-process main credential binding and its safety state until a valid replacement observation or a confirmed account transition occurs. The binding match remains restricted to the exact bearer HMAC, effective account identity, and live generation.

The cross-token identity finding is valid and fixed in head 6c1387dc460c456a17f8808607ca4cb9fcd5cbfc (base 29bb221c3cfad89e4920ac411c9681073929c152). initializeMainAccountPolicyBinding() now derives each token's account identity independently and rejects any present extracted identity that disagrees with the owned file's explicit account ID, before changing observations. The !== undefined checks also reject an explicitly empty extracted identity.

The baseline 3edfb45 failed both new conflict checks: ID-token A / access-token B / explicit account A established an incorrect fresh binding, and the same conflicting rearm replaced the previous A binding so an A request reached mocked upstream. The opaque-owned-bearer control passed. The fix rejects both conflicting reads and preserves A's existing measured block during the latter.

I retained opaque-token compatibility. The existing owned credential reader falls back to the stored account ID and permits a bearer without decoded expiry; main identity lookup has the same account fallback. A decodable JWT is not authentication proof. This binding is grounded in the pinned owned read plus exact bearer/workspace equality. Rejecting every opaque token would be a separate compatibility change, so the new control verifies that an owned opaque bearer with account A still binds and observes A's persisted 99% block.

The unconditional-clear portion of the other inline comment is covered by the withdrawn P1 reassessment. Rejected input creates no new binding and does not revoke an existing verified observation. The regression now includes malformed JSON, explicit-account conflict, and cross-token conflict, followed by a valid B transition that clears A's evidence.

Final validation passed 230 tests / 1,174 assertions across seven files in 256.25 seconds, including all 17 fresh-process scenarios. Typecheck, privacy scan, and diff check passed. An independent read-only review found no additional required corrections.

Please review the new head and resolve the two inline findings if the fixed conflict handling and existing opaque/retention contracts address them. Current-head full contributor CI, maintainer sponsorship, and explicit security review remain pending.

@luvs01 I reassessed head 6c1387dc460c456a17f8808607ca4cb9fcd5cbfc.

The cross-token identity finding is addressed.

  • src/codex/account-lifecycle.ts Lines 94-97 derives the ID-token identity and access-token identity independently.
  • The initializer rejects either decoded identity when it differs from tokens.account_id.
  • The rejection occurs before it changes observedMainChatgptAccountId, quota identity, or the process-local bearer HMAC binding.
  • Because !== undefined is used, a decoded empty identity is rejected instead of being treated as absent.

The new fresh-process test covers the previously unsafe tuple. In tests/codex-integration/main-account-hard-lock-auth.test.ts Lines 164-168, the fixture writes an ID token for the explicit account and an access token for a different account. Lines 206-209 then require no binding and normal caller-owned forwarding. This prevents the access-token HMAC from being bound to the wrong account identity.

The opaque-token behavior remains correct under the existing compatibility contract.

  • src/oauth/chatgpt.ts Lines 27-40 returns undefined for an opaque token.
  • src/codex/account-lifecycle.ts Lines 92-102 accepts an opaque owned bearer only when no decoded token identity conflicts with the explicit owned account_id.
  • The owned-opaque-99 case verifies that this owned credential reconstructs the binding and applies the persisted hard lock.

The retention behavior also remains consistent with the established policy. The retained-unknown-binding scenario now includes malformed input, explicit-account conflict, and cross-token conflict. tests/helpers/main-account-policy-startup-child.ts Lines 248-275 verifies that rejected input does not replace the prior verified A binding. A later valid B observation removes the A match and clears A policy evidence.

I found no separate demonstrated credential-ownership or caller-owned admission violation. I did not execute the test suite in this environment.

I resolved both requested inline review threads.

Learning: For the Codex main-account policy in `src/codex/account-lifecycle.ts`, `initializeMainAccountPolicyBinding()` must derive `id_token` and `access_token` account identities independently. Every decoded identity, including an explicitly empty identity string, must exactly match the owned `tokens.account_id` before the function updates the observed main identity or the process-local credential HMAC. An opaque owned bearer remains compatible when it produces no decoded identity and the owned explicit account ID is valid.
