fix(codex): preserve main locks on partial WHAM usage

[lidge-jun]

Summary

The earlier revision could erase a known short-window lock when WHAM returned a long primary, secondary_window: null, omitted tertiary, allowed: true, and limit_reached: false. Those flags do not establish complete response topology or bound omitted short usage below the local 98% threshold.

Remove that exception and preserve the strict dev parser contract. A partial two-window response updates the measured long-window usage while retaining the identity-matched blocking short tuple and its timestamps for every plan. A fresh measured short-window reading below 98% or the existing explicit window-replacement evidence can recover the account. Neither flags nor an elapsed reset alone release it.

Add regressions for live 99/100% short locks on unknown, Pro Lite, Plus, and Team plans; persisted expired short evidence; 64/97.99/98/100% long usage; malformed flags/windows; writer provenance; and measured short-window recovery. Update the contract and English/Korean account docs. These are synthetic fixtures, not evidence of a provider completeness guarantee.

This supersedes the permissive parser portion carried from #5831. It intentionally does not implement recovery from an omitted window. #6183 already supplied the credential publication fence. Ref #5831 remains open for its separately held behavior.

Merge hold: Ingwannu's CHANGES_REQUESTED remains binding until Ingwannu resolves or withdraws it. This revision removes the inference rather than claiming to prove the provider contract.

Verification

• bun test tests/codex-integration/main-quota-evidence-validation.test.ts tests/codex-integration/main-account-hard-lock-recovery.test.ts tests/codex-integration/main-quota-provenance.test.ts: 303 pass, 0 fail. The added/revised regressions produced 15 failures with the old exception before its removal.

• bun test tests/ci-workflows/file-size-ratchet.test.ts tests/test-layout.test.ts tests/test-layout-tooling.test.ts: 27 pass, 0 fail. Existing registered test file extended; no new layout entry needed.

• bun run typecheck, bun run structure:check, bun run privacy:scan, git diff --check: passed.

• cd docs-site && bun install --frozen-lockfile && bun run build: passed, 545 pages.

• Full local bun run test: failed and interrupted after over 12 minutes. The managed checkout under ~/.codex/worktrees triggers protected-home fixture cleanup failures; additional catalog/restart/launcher and Claude picker failures/timeouts cascade across the broad suite. Its broad parallel lane reported 33,347 pass, 48 skip, 654 fail and 14 errors across 1,853 files; the later issue-452 serial lane reported 9 pass/8 fail before the runner was interrupted. No full local pass is claimed, and all causes were not independently isolated. The guard is retained and unrelated test/runtime fixes are outside this PR. This local resource/environment exception leaves broad validation to exact-head Cross-platform CI, which must pass before readiness.

• Local code/security audit covers parser, identity-bound merge, hard-lock consumer, and all changed files; no credential handling, logging, destination or 98% threshold change. Independent reviewer spawn was unavailable due to its stale inherited model configuration; Ingwannu's review gate is preserved.

• Exact-head Cross-platform CI run 36657299008, pull_request event, attempt 1, completed successfully on 453bcb94634dc38782bb21ef5f4f45ddd11fd334: all four Linux test shards, static gates, API/storage/structure checks, docs build, Docker, both keyring checks and both npm-global smoke tests passed, followed by the aggregate gate. All 17 selected jobs passed. The eight skipped jobs were not selected for this PR; no full Windows/macOS suite execution is claimed.

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. Local audit is documented above; outstanding maintainer objections remain a separate merge gate.

Summary by CodeRabbit

• Documentation
  • Clarified how quota protection handles incomplete usage-window data: long-window usage can be updated while a previously known short-window block remains in place.
  • A fresh short-window reading below 98% can clear that block; an elapsed reset time alone does not.
  • Clarified that omitted window data remains unknown, even when other quota indicators suggest no limit has been reached.

Merge Risk: 🔵 Low · up to 453bc

The lock-retention clarification and regression coverage introduce no demonstrated runtime failure. Qualify the long-window update claim in the contract and both account guides; the remaining risk is bounded documentation inaccuracy.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 453bc

The change preserves known quota blocks when usage data is incomplete. No expanded access or credential authority was identified. Remaining uncertainty concerns the provider’s response guarantees and an unavailable target-branch comparison.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The demonstrated security-relevant outcome is admission state for the current main credential identity. The examined change restricts which provider observations may clear that state; it does not demonstrate expanded authority over other accounts, tenants, services, or environments.

Security Findings and Attack Paths

• observed — The examined bypass hypothesis was that favorable provider flags could cause an omitted short window to erase a known block. Head does not grant replacement authority to that partial response, and regression cases retain the block across malformed flags, differing long-window readings, and superseded writers. This supports rejecting that hypothesis for the examined head path, not declaring unexamined surfaces safe.

Trust Boundaries and Controls

• observed — External usage data passes through policy validation before it can replace local blocking evidence. Invalid numeric usage yields no policy observation, omitted-window completeness is not inferred from flags, and publication separately checks writer generation and credential identity.

Resilience and Maintainability Implications

• observed — Repeated partial observations retain the known block, measured short recovery remains available, and stale dispatches or unsuccessful asynchronous probes do not publish replacement evidence. These controls contain failure without weakening the admission policy; full end-to-end interruption coverage remains narrower than the inspected source paths.

이 PR은 메인 계정의 옛 5시간 잠금이 새 사용량 조회 뒤에도 안 풀리는 경우를 고쳐요. WHAM이 3차 창을 빼 보내고, 2차 창은 null, 1차 창은 24시간 이상일 때예요. 화면의 사용량은 낮은데 정책 캐시는 예전 5시간 100%를 붙잡고 있었어요.

parseMainPolicyUsageQuota는 그 모양만 받아요. 2차가 정확히 null이고, 3차 키가 응답에 없고, allowed가 불리언 true, limit_reached가 불리언 false이며, 1차 창이 86400초 이상이고 사용량 숫자가 있을 때만 옛 짧은 창을 지워요. 숫자가 깨졌거나 칸이 비었거나 5시간 창이 아직 있으면 잠금을 유지해요. 98% 기준은 그대로예요. 64%와 97.99%면 잠금이 풀리고, 98%와 100%면 짧은 창만 지우고 잠금은 남아요.

이 가지는 초안이에요. 바탕은 dev가 아니라 #6183 가지 codex/rt5-account-pool-main-lock이에요. #6183은 #6179 위에 쌓여 있어요. #5831은 제목이 같고 아직 열려 있어요. 본문은 이 파서가 #5831의 파서 부분이라고 해요.

라인 - src/codex/quota.ts 835행 allowedTwoWindow. 3차 키가 없고 위 두 플래그만 맞으면 짧은 창이 없다고 봐요. 그 플래그가 주간 창만 보고 켜진 것인지, 5시간 창이 정말 없는 것인지는 이 코드가 구분하지 못해요. 테스트는 그 JSON 모양만 확인해요. WHAM이 다른 이유로 3차를 빼면, 아직 남은 5시간 잠금이 풀려요.

메인테이너의 판단이 필요한 지점

본문도 공급자 확인 전에는 머지하지 말라고 해요. 3차를 뺀 응답이 짧은 창이 없다는 완전한 증거인지는 WHAM을 보내는 쪽이 확인해야 해요. 테스트로 그 약속을 증명할 수 없어요.

이 머리의 CI는 아직 줄 서 있어요. 본문은 로컬 테스트를 일부러 건너뛰었다고 해요. 체크리스트의 보안 항목은 비어 있어요. 가정이 틀리면 진짜 차단이 풀려요.

너의 추천

WHAM 쪽이 이 응답을 짧은 창 없음의 증거로 확인한 뒤에 835행을 머지하세요. #6179와 #6183이 dev에 들어간 뒤에 이 PR의 바탕을 dev로 바꾸세요. #5831은 같은 제목으로 아직 열려 있으니 닫으세요.

[Ingwannu]

Maintainer hold confirmed on exact head 8e5a46c. The implementation is deliberately narrow, but the decisive premise is still external: omitted tertiary + explicit null secondary + allowed=true + limit_reached=false + a measured >=24h primary must mean that no governing short window exists. Source tests can validate shape handling, not that provider contract. Keep this draft unmergeable until that contract is confirmed, #6183 lands, the branch is rebased onto current dev, and exact-head CI is green.

[lidge-jun]

Coordinator question: is #5831 fully covered? Not yet. #6183 (merged as 59c222d) landed #5831's credential-publication fence. The rule #5831 is named for, which accepts the two-window WHAM shape (omitted tertiary, explicit-null secondary, measured primary of at least 24 h, exact allowed/limit_reached) as evidence that clears a stale short-window block, exists only in this draft. It stays held until the provider/owner confirms that shape is complete evidence of no governing short window. Please keep #5831 open until this PR lands or is dropped.

This PR is now rebased onto dev (4bce789, a single commit by 정우철) and retargeted to dev.

[Ingwannu]

Reviewed exact head 4bce789. The branch is current and mechanically clean, but the admission contract remains unproven. The implementation still treats long primary + secondary:null + omitted tertiary + allowed:true + limit_reached:false as authoritative proof that no short window exists. Those booleans do not establish response-topology completeness or that an omitted short window is below the local 98% lock threshold; a still-99% omitted short window can therefore be erased and weekly 64% can move the local hard lock to ready.

The only provenance is a test comment describing a sanitized observed shape, while the structure doc explicitly says completeness is not independently confirmed. The observed fixture is also plan_type=prolite but the implementation applies to every plan. Keep this held until the producer/provider contract confirms omitted tertiary means no governing short window (and whether that is plan-scoped), then encode that scope with a captured fixture/regression.

[lidge-jun]

@Ingwannu Agreed; this stays held. allowed: true and limit_reached: false do not prove the response topology is complete, and they cannot bound an omitted short window below the local 98% lock. As written, a still-99% short window could be erased and a 64% weekly reading could move the hard lock to ready. The only provenance is one sanitized prolite observation, but the rule applies to every plan. No code or test change can close that gap. It needs the producer/provider contract (does an omitted tertiary mean no governing short window, and is that plan-scoped?) plus a captured fixture encoding that scope.

Lane decision for release train 5: this PR does not land this train. It stays a draft with the branch kept. #6183 already landed the credential-publication part of #5831, and the two-window admission rule here is the only remaining part. For the coordinator: please leave #5831 open with a note pointing at this PR until the contract is confirmed; then this rule can be re-scoped (per plan if needed) with a captured fixture and a regression.

[lidge-jun]

@Ingwannu Addressed the objection by removing the omitted-tertiary admission exception, rather than asserting a provider completeness guarantee.

At 453bcb94634dc38782bb21ef5f4f45ddd11fd334, allowed and limit_reached no longer authorize shortWindowAbsent. A long primary plus null secondary and omitted tertiary is partial for every plan: measured long usage updates, but the known blocking short tuple and its original timestamps remain. A fresh measured short reading below 98% or the existing explicit window-replacement evidence remains the recovery path. The PR no longer implements unlock from an omitted window and does not claim #5831 is complete.

The regressions exercise your concrete counterexample: live short 99% plus weekly 64% with allowed=true/limit_reached=false stays blocked, including unknown, Pro Lite, Plus and Team plans. They also cover short 100%, persisted elapsed-reset evidence, weekly 97.99/98/100%, malformed flags/windows, writer provenance, and measured short recovery. The fixtures are synthetic and are not presented as provider-contract evidence. The old exception failed 15 of these cases; the corrected focused suites pass 303 tests.

The branch is rebased onto current dev, and the English/Korean account docs and structure contract now match this strict behavior.

Exact-head Cross-platform CI run 36657299008, pull_request event, attempt 1, completed successfully on 453bcb94634dc38782bb21ef5f4f45ddd11fd334: all four Linux test shards, static gates, API/storage/structure checks, docs build, Docker, both keyring checks and both npm-global smoke tests passed, followed by the aggregate gate. All 17 selected jobs passed. The eight skipped jobs were not selected for this PR; no full Windows/macOS suite execution is claimed.

The full local suite failed in this managed checkout and was interrupted after more than 12 minutes. Its broad lane reported 33,347 pass, 48 skip, 654 fail and 14 errors; protected-home fixture cleanup and startup failures were among the observed signatures. Typecheck, 303 focused tests, 27 ratchet/layout guard tests, structure/privacy checks and the 545-page docs build passed. The PR records the scope and limitations.

assert-mergeable-review.sh --maintainer-integration 6188 lidge-jun/opencodex still exits 1 because your CHANGES_REQUESTED remains outstanding. I am marking this ready for your re-review after CI completion; I will not dismiss the review or merge while it remains outstanding.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Separate all-plan block retention from long-window updates.

The parser does not update long-window usage for every plan. For plan_type: "free" or "go", a primary window with used_percent: 64 and limit_window_seconds: 604800, null secondary, and omitted tertiary produces no quota observation. src/codex/plan.ts, Lines 14-17, selects monthly-only parsing. src/codex/quota.ts, Lines 909-915 and 931, returns null because monthly usage is absent.

Preserve the all-plan claim for short-window block retention. Qualify the usage-update claim to cover only usage the parser accepts.
