Summary

  • Classify incomplete quota terminals from structured reasons/codes or supported quota messages, preserving explicit HTTP 402 and authoritative policy/authentication refusals.
  • Update account and spawn-fallback health, and publish late terminal metadata to the committed combo parent before logging; discarded children cannot pollute the parent.
  • Carries the quota slice of fix(responses): fallback to routed compaction on 404 and enable quota failover on incomplete terminal #3769. Native compact 404 fallback remains deferred pending identity and replacement-history preservation.

Verification

  • Full Cross-platform CI lane=all: all 25 jobs passed at final descendant bf94d8dfa7b91c0e4acb96b2afce64d3c9a5ddde, including Linux, all six Windows shards and the macOS full-control run.
  • This layer's exact head is d17d323e6505c0f37bc4cee99f21dede1efae0ac and is an ancestor of that tested final head. Lower-head suites were intentionally not run separately, per the maintainer's final-first validation instruction; they are not represented as independently passing checks.
  • Relevant coverage: Reason/code-only quota, ordinary incomplete neutrality, exact status preservation, all three terminal reporters, post-output HTTP combo logging and discarded-child isolation.
  • Independent Astra high security/correctness reviews completed; valid automated findings were fixed. Local tests, typecheck, builds and installation were not run, per explicit maintainer instruction.
  • Protocol cases were checked against the local Codex implementation and official WebSocket documentation.

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

@lidge-jun explicitly authorized admin integration into dev without a second maintainer approval under MAINTAINERS.md. This is maintainer integration, not self-approval. The final aggregate evidence above and its ancestry cover this stack; lower-head execution is explicitly deferred. Merge bottom-up with merge commits, preserving contributor attribution. Because automatic branch deletion is enabled, move a direct child's base to dev immediately before merging its parent. No native GitHub stack registration or repository-policy change is used.

📝 Walkthrough

Walkthrough

Native forward incomplete responses now detect quota or rate-limit evidence, record HTTP 429 or 402 outcomes, update account and subagent health, preserve refusal precedence, and avoid replaying ordinary incomplete terminals. Tests and documentation cover the new behavior.

Changes

Incomplete quota terminal handling

Layer / File(s) Summary
Quota terminal classification
src/server/request-log.ts
captureTerminalHttpStatus recognizes structured quota and rate-limit evidence on response.incomplete terminals. Ordinary incomplete reasons and structured refusals keep their existing behavior.
Quota outcome propagation
src/server/responses/core.ts
Forward terminal recorders prefer resolved 429 or 402 quota statuses, copy child terminal metadata to parent logs, and record subagent quota failures for incomplete terminals across passthrough, eager-relay, and tee paths.
Behavior validation and documentation
tests/responses/responses-forward-incomplete-quota.test.ts, tests/usage/request-log.test.ts, tests/server/server-combo-failover-e2e.test.ts, docs-site/src/content/docs/reference/architecture.md, structure/04-transports-and-sidecars.md, scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json
Tests cover payload classification, transport reporting, account health, parent metadata, cleanup, and precedence rules. Documentation describes the behavior, and test-layout mappings register the new test file.

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

Merge Risk: 🟡 Moderate · up to d17d3

The quota-attribution behavior is covered broadly, but a duplicate declaration currently prevents the combo failover test file from parsing. Fix this test syntax error before merging.

설명

이 PR은 Track1 스택(592d)의 첫 층입니다. 지금 dev HEAD는 24c761a05(package 2.45.0, 직전 #3787 credits)이고, 이 DRAFT는 base=dev / head=codex/track1-01-quota-592d(a1fb1e276)입니다. 아래 층 #3792#3793#3794가 이 커밋 위에 쌓입니다. 열려 있는 #3769에서 incomplete 쿼터 귀속만 잘라 온 조각이고, compact 404 fallback·identity/history 보존은 의도적으로 빼 두었습니다. 로컬 typecheck/build는 돌리지 말고 최종 후손 CI만 본다는 메인테이너 지시가 본문에 적혀 있습니다. 글을 쓰는 시점의 최종 head a4edcc294 Cross-platform CI(34048125388)는 아직 in_progress입니다.

현재 devcodexForwardTerminalOutcomeRecorder(src/server/responses/core.ts)는 status === "incomplete"이면 무조건 200으로 계정 헬스를 기록합니다. 그래서 ChatGPT forward가 HTTP 200 SSE로 response.incomplete + usage_limit_reached/rate_limit_exceeded를 보내도 soft-avoid가 지워지고 sticky affinity가 exhausted 계정에 남습니다. captureTerminalHttpStatus(src/server/request-log.ts)도 incomplete에서는 cyber-policy만 보고, response.failed가 아니면 early return 해서 terminalHttpStatus를 안 남깁니다. 이 PR은 (1) structured incomplete_details.reason과 error code/type, 그리고 ordinary reason이 아닐 때만 message 기반 isRateLimitOrQuotaFailureMessage로 429를 캡처하고, (2) recorder가 quotaStatus(429/402)가 있으면 incomplete도 벌점 outcome으로 보내며, (3) parent/WS/SSE reporter 세 곳이 failed뿐 아니라 incomplete에서도 spawn-fallback 헬스에 기록하게 맞춥니다. ordinary max_output_tokens/content_filter/steered/upstream_stall_timeout/adapter_eof는 쿨다운하지 않습니다. cyber-policy는 그대로 400 우선입니다.

이미 머지된 #3607(쿼터 reset 마커 중복 제거)과 #3606(combo cooldown + reset metadata)과 맞물리는 축입니다. incomplete를 진짜 쿼터로 분류해야 그 쿨다운·리셋 메타가 쓸모 있습니다. 테스트는 새 tests/responses/responses-forward-incomplete-quota.test.ts(337줄)와 tests/usage/request-log.test.ts 보강으로, reason-only·code·rate_limit_error·message, ordinary 비벌점, policy 우선, 502 override가 typed 429를 지우지 않는지, parent/guarded-WS/native-SSE reporter까지 endpoint 수준으로 돌립니다. win32는 field-backfill eager 때문에 native-SSE 케이스를 skip합니다. types.ts/config.ts 대분리와 겹치지 않는 독립 bugfix이라 close-don't-rebase 대상이 아닙니다. DRAFT+스택이니 이 층만 따로 머지하지 말고 최종 CI·ancestry를 보고 한 번에 올리는 전제입니다.

경로 src/server/request-log.ts captureTerminalHttpStatus - incomplete에 대해 quotaTag(reason|code|type)와 ordinary-reason 화이트리스트를 도입한다. 예전 #3769 리뷰에서 지적했던 reason-only 공백을 직접 메운다. structuredRefusal(400/401/403/499)이 있으면 429 분기를 건너뛴다. auth 실패가 incomplete에만 실리면 terminalHttpStatus가 비는 경로가 남는다(테스트도 그 동작을 고정).

경로 src/server/responses/core.ts codexForwardTerminalOutcomeRecorder - incomplete && quotaStatus === undefined일 때만 200 성공 기록을 유지한다. quotaStatus는 override와 logCtx.terminalHttpStatus 중 429/402를 고른다. generic 502 override가 typed 429를 덮어쓰지 않게 한 점이 핵심이다.

경로 src/server/responses/core.ts parent/guarded-WS/native-SSE reporter 세 곳 - status === "failed" || status === "incomplete"로 넓히고 .find(429|402)로 단순화한다. fixed-account는 여전히 spawn 기록을 건너뛴다. 풀 계정에서만 thread-spawn 헬스에 반영된다.

경로 tests/responses/responses-forward-incomplete-quota.test.ts - 실제 handleResponses + upstream Bun.serve/WebSocket redirect로 parent-recorder·guarded-ws·native-sse를 검증한다. isModelHealthBlockedgetCodexAccountCooldownUntil을 같이 읽어 recorder와 spawn store가 분리되어 있음을 증명한다. layout.json / test-layout-expected.json에 파일명도 등록했다.

경로 docs architecture.md / structure/04_transports-and-sidecars.md - “structured reason은 message 없이도 인정, ordinary incomplete는 쿨 안 함, policy 우선, output 뒤 replay 없음, fixed-account 유지”를 짧게 적었다. #3607/#3606 불변식과 읽기 방향이 맞다.

메인테이너의 판단이 필요한 지점

  • Track1을 최종 CI 통과 후 통째로 올릴지, 01 층만 먼저 dev에 넣을지(아래 층 base가 이 브랜치라 순서 의존이 큼)
  • incomplete에 실린 auth-shaped error를 401로 올릴지, 지금처럼 “쿼터도 아니고 failed도 아니라서 상태 없음”으로 둘지
  • ordinary reason 화이트리스트에 adapter_eof만 문서/테스트에 넣고 "unknown"은 테스트만 있는지, 목록을 더 엄격히 맞출지
  • 최종 CI(a4edcc294) 실패 시 이 층 head에 진단 CI를 따로 돌릴지(본문은 failure 시에만 lower-head CI라고 함)

너의 추천
스택 01로 두고 최종 Cross-platform CI가 green이면 #3792#3794와 함께 dev에 올리는 쪽을 추천합니다. incomplete 쿼터를 200 성공으로 지우던 dev 동작은 멀티 계정 페일오버를 실제로 막고, 이 패치는 reason-only까지 커버하며 policy/ordinary 경계를 테스트로 고정합니다. 단독 머지도 가능하지만 base 체인이 있어 통째 랜딩이 덜 헷갈립니다. types/config 대분리로 닫을 PR은 아닙니다. DRAFT 해제는 CI·ancestry 기록 후.

Carry the quota-attribution slice of #3769. Keep canonical compact 404 fallback deferred pending identity and history preservation. Local checks deferred to final hosted CI by maintainer instruction.
