Summary

Fixes a stale account-level 5h quota bar remaining on a weekly-only Codex Pro pool account after the Spark attribution fix (#4122). Partial refreshes copied the obsolete short tuple while renewing the cache-wide timestamp, so the six-hour disk TTL never removed it.

The display/rotation merge now discards an omitted short tuple after its reset deadline. Explicit incoming readings, future deadlines, and unknown deadlines retain their previous behavior. Main-account hard-lock evidence remains separate and cannot be cleared by elapsed time or partial updates. Codex reset-notification history retains the absent short baseline and original observation time, so the next real rollover still produces one notification; explicit account cleanup clears it.

The current retention contract is documented in the owned structure pages. No layout or component change.

Verification

  • Added regression coverage for WHAM/Spark/weekly/credits-only cleanup, seconds/milliseconds and legacy updates, main-policy preservation until fresh zero, repeated partial updates followed by exactly one reset notification, persisted observation clocks, account clear, and unchanged provider replacement behavior.
  • Two independent reviewers using the parent model found the policy and notification regressions; both were corrected and re-reviewed.
  • Local tests, typecheck, builds and dependency installation: NOT RUN, per the user's instruction. Pushes use --no-verify; remote CI on the final PR head is the merge gate.
  • git diff --check: passed.

Review disposition: the earlier CodeRabbit suggestion to replace a known main-policy short reading with percentage-free short metadata is rejected. That would discard measured blocking evidence without recovery. The original policy merge semantics are preserved and main-account-hard-lock-policy.test.ts now asserts retention across credits-only, weekly-only, and metadata-only updates followed by fresh-zero recovery.

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.

Maintainer integration

Maintainer lidge-jun elects integration into dev under MAINTAINERS.md without a second maintainer approval. This is not self-approval. Final reviewed head: d7b4cc9ba26242eb48e0841a869f5fb0ef6670f8.

Cross-platform CI run 34671020142 succeeded: 19 jobs passed, two conditional jobs skipped. All four Linux test shards, both macOS test shards and gates passed. Current PR checks, including CodeRabbit, are successful; the full Windows suite was conditionally skipped, while Windows keyring and npm smoke ran successfully. Local product suites remain NOT RUN by user instruction. Independent inherited-model reviews verified the main-policy and notification corrections; existing review threads are resolved.

📝 Walkthrough

Walkthrough

The quota merge and update paths discard elapsed account-level short-window tuples while preserving active tuples, policy evidence, and reset history. Tests cover Spark, WHAM, weekly-only, credits-only, hard-lock, and reset-observation scenarios.

Changes

Phantom account short quota

Layer / File(s) Summary
Quota behavior and acceptance contract
devlog/_plan/260912_phantom_account_short_quota/*, structure/providers/openai-tiers.md, structure/*.md
The plans and provider documentation define expired short-window removal, policy-evidence retention, reset-history retention, and the related acceptance cases.
Elapsed short carry implementation
src/codex/quota.ts, src/codex/routing.ts
resetAtToMs centralizes seconds-to-milliseconds conversion. mergeAccountQuota and updateAccountQuota stop carrying expired short tuples unless policy evidence requires retention.
Reset history retention wiring
src/quota/reset-observer.ts, src/quota/reset-seen-store.ts
Codex requests retention for an absent short window. The reset-seen store preserves the original observation clock for that opt-in path.
Regression validation
tests/codex-integration/codex-quota-parser-parity.test.ts, tests/codex-integration/main-account-hard-lock-policy.test.ts, tests/usage/*
Tests cover refresh variants, timestamp units, active and explicit short tuples, hard-lock evidence, reset events, persistence, and default replacement behavior.

이 PR은 Codex Pro 풀 계정 대시보드에 이미 끝난 계정 단위 5시간(short) 바가 계속 남는 문제를 고칩니다. #4122가 Spark 5시간 값을 계정 short 슬롯에 새로 쓰지 않게 막았는데도, 어떤 Pro 계정은 여전히 5시간 리셋 9월 10일 02:24 4% 같은 줄을 보여 줍니다. 원인은 src/codex/quota.ts의 mergeAccountQuota입니다. short가 없는 부분 갱신(주간만, 또는 Spark customWindows만)이 오면 예전 short 묶음 전체를 그대로 복사하고, setAccountQuotaFromParsed가 updatedAt을 지금으로 다시 찍습니다. 디스크 TTL(QUOTA_DISK_MAX_AGE_MS = 6시간)은 updatedAt만 보므로, 이미 지난 shortResetAt이 있어도 캐시가 만료되지 않고 유령이 남습니다.

지금 dev HEAD(e7f7487b3)의 같은 파일에는 아직 예전 동작이 있습니다. credits-only 분기와 partial short else 분기, 그리고 updateAccountQuota가 short 필드를 조건 없이 옮깁니다. 이 브랜치는 shortResetHasElapsed와 assignCarriedShort를 넣고, reset이 이미 지난 short만 옮기지 않습니다. 아직 열린 Plus/Team 5시간 창은 주간만 오는 갱신에서도 남습니다. 반대로 setAccountQuotaFromParsed로 short가 명시적으로 들어오면(리셋이 과거여도) 그대로 저장합니다. 자동 새로고침·라우팅 픽스처가 그 리셋 시각을 쓰기 때문입니다.

초·밀리초 판별 상수 RESET_AT_SECONDS_MAX(10_000_000_000)는 src/codex/routing.ts의 isTerminalShortWindow와 src/codex/main-account-hard-lock.ts가 이미 쓰는 기준과 맞춥니다. GUI(gui/src/codex-quota-utils.ts, QuotaBars.tsx)는 short를 만료 검사 없이 그리므로, 캐시에서 유령 튜플을 빼는 쪽이 맞는 고침입니다. 회귀 테스트 네 줄이 tests/codex-integration/codex-quota-parser-parity.test.ts에 들어 있고, Spark 생략·주간만·아직 열린 short·명시 입력 elapsed를 각각 덮습니다. types.ts/config.ts 분리 캠페인과 무관한 독립 핫픽스이고, Local-tab 카탈로그 기차(#4324/#4325)와도 겹치지 않습니다. 패키지는 여전히 2.52.0 선상입니다.

라인 229~245 - shortResetHasElapsed가 reset이 없거나 잘못된 값이면 false라서, shortPercent만 있고 shortResetAt이 없는 오래된 튜플은 계속 옮겨집니다. 의도(나이 계산 불가)라면 괜찮지만, 그런 오염이 실제로 있으면 TTL만으로는 안 빠질 수 있습니다.
src/codex/quota.ts / RESET_AT_SECONDS_MAX - routing·hard-lock과 같은 리터럴이 세 곳에 있습니다. 나중에 한곳만 바꾸면 초/ms 판별이 어긋날 수 있습니다.
gui/src/codex-quota-utils.ts · QuotaBars.tsx - 캐시에 남은 short를 만료 없이 그립니다. 이번 PR 범위 밖이지만, 캐시 고침이 빠진 경로가 있으면 UI는 그대로 유령을 보여 줍니다.
devlog/_plan/260912_phantom_account_short_quota/ - 플랜·페이즈 문서가 큽니다. 머지 후 _fin으로 옮길지, 본문만으로 충분한지 정리하면 큐가 덜 헷갈립니다.

메인테이너의 판단이 필요한 지점

  • shortResetAt 없는 shortPercent만 남은 오염도 같이 버릴지(이번엔 reset 경과만 버림)
  • RESET_AT_SECONDS_MAX를 공유 헬퍼로 묶을 follow-up을 받을지, 이번 PR은 그대로 둘지
  • 라이브 캐시에서 해당 Pro 계정이 다음 일반 갱신 뒤 바로 깨끗한지 한 번 확인할지(PR 본문 증거는 이미 있음)

A Codex Pro pool account kept rendering a 5h quota bar whose reset instant had
already passed, while its identically-limited Pro peers showed weekly only. Pro
has no account-level 5h window; the bar was the residue of the Spark attribution
defect (#4122), which stopped new model-specific 5h windows from landing in the
account short slot but left the already-written tuples to "the six-hour hydration
TTL".

That TTL can never fire on them. mergeAccountQuota treats the absence of short*
in an incoming snapshot as a partial update and copies the whole stored tuple
forward, and every merge stamps a fresh updatedAt - which is the field disk
hydration ages against. A Pro refresh reports a weekly primary window and no
short window at all, so the residue was republished on every refresh and
survived restarts.

An elapsed reset now stops the carry: the tuple describes a window that has
already rolled over, so merge drops it instead of re-dating it. An explicit
incoming short is still stored as observed, a still-open window is still carried,
and identity-bound policy evidence no longer treats an elapsed reading as known.
The seconds/milliseconds split both reset instants can be written in is now one
exported helper shared with the routing scorer.

Bounded consequence: a credits-only or weekly-only merge arriving between a reset
and the next observation also clears fiveHourAvailable for auto-refresh, which
keeps its own retained boundary and re-observes the window on the next real
response.
Plan and phase doc for the phantom account-level 5h row: live cache evidence,
the refuted GUI/WHAM/auth-api alternatives, the accepted auto-refresh
consequence, and the NOT RUN record for the local suites.

351-368: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Preserve explicit short metadata in policy merges.

At src/codex/quota.ts:351-355, preserveKnownShort checks only quota.shortPercent. parseUpstreamQuotaHeaders can produce policy evidence with shortResetAt or shortWindowSeconds when short usage is missing. Because snapshotHasShort treats that metadata as explicit, the code enters assignCarriedShort and discards the incoming metadata in favor of the existing tuple. This violates the phase-1 contract that any incoming short* fields, including elapsed tuples, remain stored. Change the guard to require !snapshotHasShort(quota), so existing short data is carried only when the incoming snapshot omits the entire short tuple.
