- Around line 1581-1604: Extract the duplicated nativeMainSelectionOnly and
isMainAccountTokenLive filtering into a sharedStateSelectionOptions helper near
getPoolAccountPlanForSelection, preserving undefined handling and the existing
truthiness/undefined checks. Use this helper for both sharedSelectionOptions
construction and releaseDrainedCodexAccountPin, while retaining the conditional
modelScopedSelection behavior so the pin call always receives the filtered
subset.
- Around line 1749-1764: Update the applyQuotaAutoSwitch and
applyFailureFailover calls to pass !preserveSharedSelectionForModelDetour &&
!modelScopedSelection, preventing quota or failure commits during model-scoped
selection while preserving existing behavior otherwise. Add focused regression
tests covering both quota switching and failure failover with
modelScopedSelection enabled.
In `@src/server/responses/core.ts`:
- Around line 1661-1672: Update resolveCodexModelEntitlementsForRequest to
capture the caught discovery error, log a bounded warning containing its
redacted details via the existing redactSecretString utility, then continue
throwing CodexModelEligibilityUnavailableError so the client response contract
remains unchanged.
In `@tests/codex-auth-context.test.ts`:
- Around line 514-526: Update the model-only stability test around
resolveCodexAuthContext to exercise the model-scoped path: use the gated model
selector and provide a resolveCodexModelEntitlements seam granting gpt-5.5 to
pool-a, following the existing pattern in the file. Preserve the assertions that
the shared selection remains pool-a and the resolved account is pool-a.

이 풀은 이미 합쳐진 #2623 과 #2629 가 남긴 구멍을 막는 후속이다. 지금 CURRENT 남는 구멍은 두 갈래다. 첫째는 잠깐 비우는 동안(native-main drain) 본 계정 자격 파일을 읽으면 안 되는데, 지금 HEAD 는 읽는다. src/codex/routing.ts 1123-1124줄 getPoolAccountPlan 은 메인이면 getMainAccountPlan 을 부른다. 그 함수는 src/codex/main-account.ts 21-30줄에서 한 번도 안 읽었으면 readCodexTokens 로 auth.json 을 연다. 같은 파일 995-998줄 hasCodexQuotaHeadroom 과 1140줄 pickLowerUsageAccount, 1536-1539줄 스레드 재평가가 그 길을 탄다. 1325-1331줄 releaseDrainedCodexAccountPin 도 핀이 메인일 때 같은 점수를 매긴다. 비우는 동안 자격 파일을 열면, 나중에 진짜 계획이 와도 빈 값이 캐시에 남아 잘못된 점수가 난다. 둘째는 모델 자격만 다른 요청이 운영자가 고른 공유 계정과 스레드 붙임을 바꿔 버리는 것이다. src/codex/routing.ts 1509줄은 핀을 먼저 거두고, 1519줄은 modelEligibleAccountIds 로 이번 요청만 걸러낸다. 자격이 없으면 1557줄에서 스레드 붙임을 지운다. 1560줄 pickUnboundStrategyAccount 는 commit 이 참이면 공유 활성 계정과 붙임을 같이 기록한다. 1567줄과 1573줄 setActiveCodexAccount 도 이번 모델 우회를 공유 커서에 쓴다. 운영자가 고른 계정은 그대로 두고, 이번 요청만 다른 계정으로 가야 한다. 인증 쪽도 같은 이야기다. src/codex/auth-context.ts 385줄 nativeMainReadsForbidden 은 시작 복구이거나 이번 턴 비움이다. 404-405줄 nativeMainSelectionOnly 는 이번 턴 비움만 참이다. 그런데 444줄은 nativeMainTrafficBlocked 일 때만 CodexMainProfileDrainingError 를 던진다. 잠깐 비우기만 있고 건강한 풀 계정이 없으면, 막힌 자격 파일을 못 읽은 것을 계정 없음이나 모델 자격 거절로 잘못 말한다. 452-461줄 원자 claim 이 메인을 거절해야 할 자리인데, 그 앞 분류가 먼저 틀린다. 서브에이전트 폴백도 같다. src/codex/subagent-model-fallback.ts 279-303줄 isSubagentModelUnavailable 은 미리보기가 고른 계정이 쓰이지 않으면 그 모델을 버린다. 잠깐 비우는 동안 자격 조회가 메인을 빼면, 미리보기는 메인을 센티널로 돌려줄 수 있다. 지금 HEAD 는 그걸 모델 불가로 보고 다음 모델로 넘어간다. 원자 claim 이 정비 중이라고 말할 기회를 폴백이 가로챈다. 서버 응답 경로도 자격 조회 실패를 그대로 던진다. src/server/responses/core.ts 1599줄은 resolveCodexModelEntitlements 를 감싸지 않는다. 1648줄 resolveSubagentFallbackModelEligibility 도 같다. 2510-2515줄 미리보기 호출에는 catch 가 없다. 1629-1634줄은 CodexAuthContextError 만 응답으로 바꾸고, 그 밖의 에러는 다시 던진다. 자격 조회가 실패하면 내부 문구가 밖으로 새거나 요청이 500 으로 죽을 수 있다. 이 풀은 그 네 줄을 한 번에 고친다. 비우는 동안 계획 점수는 메인을 읽지 않는다. 모델 자격 우회는 공유 활성/핀/기존 붙임을 남기고, 라운드로빈만 이번 요청 범위에서 돌린다. 건강한 풀이 없으면 메인을 읽지 않는 센티널로 돌려 원자 claim 이 정비 중을 말하게 한다. 자격 조회 실패는 빨간 글 없는 503 한 장으로 모은다. 시험이 그 경계를 잠근다. 방향은 맞다. 다만 아직 드래프트이고, 작성자 본문이 메인테이너 보안 검토를 요청한다. 인증과 생명주기 경계라 스폰서 없이 합치면 안 된다. 본문은 #2629 의 Windows fileURLToPath 회귀를 이 커밋이 고친다고 적는다. 실제 파일 일곱 개에는 그 변경이 없다. 지금 HEAD 의 tests/install-scripts.test.ts 15줄과 24줄에 이미 fileURLToPath 가 있다. 본문이 오래된 것이다. src/codex/routing.ts releaseDrainedCodexAccountPin - 메인이고 잠깐 비우면 일찍 돌아가지만, 그 다음 hasCodexQuotaHeadroom(config, pinned) 에는 selectionOptions 를 안 넘긴다. 지금 경로는 안전하지만 나중에 이른 반환을 지우면 같은 읽기 구멍이 다시 열린다 메인테이너의 판단이 필요한 지점

I reviewed exact head 3d3f000fcd3bab3baa00c1496dd242d294447292. The earlier over-broad catch and shared-state commit findings are fixed on this head, and the remaining review threads are resolved. I am not applying maintainer-sponsored yet for two blockers.
- The new retryable-503 contract is not currently produced by the real entitlement resolver.
CodexModelEntitlementDiscoveryUnavailableErroris defined, imported by Responses, and constructed by tests, but no production source constructs or throws it. Normal fetch, timeout, parse, and bounded-body failures infetchAccountModelsare converted toconfirmed: false; unrelated throws keep their generic path. As written, the new 503 mapping is therefore test-seam-only and does not prove the claimed operational failure behavior. Classify the intended real discovery-unavailable condition at the source boundary, then add an end-to-end regression through the production resolver path. If no existing production condition should become 503, remove or explicitly defer this dead contract instead of presenting it as completed behavior. - This security-sensitive head is 49 commits behind current
dev(779b6090c) and the required hygiene/target checks are failing. Rebase onto currentdev, rerun the focused routing/auth suites plus full exact-head CI and privacy scan, then request security sponsorship again.
The drain read-fence and request-scoped routing direction remains valuable, but this should stay draft until the production error boundary and current-head validation are real.

Reviewed as part of the 260827 bug-PR merge round. Not merged — it needs a maintainer's security decision, and that is the only thing standing in its way. The hygiene gate is right to hold it: I did not apply What the auth surface actually is — 14 lines. Hoisting Verified at the merged tree (
That last point is worth stating explicitly: So the technical evidence is good. The remaining question is one only a maintainer can answer: is widening the fence condition to cover a turn drain the behavior you want? It means a drained main profile produces a retryable fence rather than an entitlement denial — better for the caller, but it is a change in what an auth failure means, which is exactly the class of decision @lidge-jun @Ingwannu — over to you. Everything else in the round is dispositioned; this and #2497 are the two waiting on a person. |

Incremental gate on current head b0f328462f007d62a1435756fd0e9da3cc5d2f6d: the prior dead retryable-503 contract is gone, so I am not carrying that old blocker forward. The branch still cannot receive security sponsorship on this base.
Its actual base is 779b6090c56bb94fbe47b155eade5f3b5110d747; current dev is 8b1b65b8d858d3b92e4fd4852e9e368d43e73f39. The head is now 179 dev commits behind, and src/server/responses/core.ts is modified both by this PR and by the intervening dev range. That file is part of the request/auth-routing boundary this PR changes, so GitHub's textual mergeability is not evidence that the combined behavior is still correct.
Please rebase onto current dev and request review on the new exact head. I will then re-review the auth-context/routing/core delta and run the focused auth, routing, entitlement, and subagent fallback suites in isolated homes. Until that happens, please do not apply maintainer-sponsored or approve the waiting fork workflows.

Heads up: I rebased this branch onto current The rebase was clean, and so was the behavior — that is the news. The review that withheld sponsorship was right to: 192 commits of drift on Your work is byte-identical after the rebase: Pushed with Verification on the rebased treeThe Lab-boundary guard matters specifically here: this PR touches On the change itselfTwo things read as genuinely careful rather than incidental:
What still needs a humanThis is an auth-routing surface, so @Ingwannu — you asked for a rebase onto current |
…ded off dev 50e9556 -> 29be459. #2740 merged, #2693 closed as superseded by #2794. The useful surprise: #2638 rebased across 195 commits with ZERO conflicts and 15375/0 on the rebased tree, beating my prediction. #2497 with the same 'far behind' shape does not rebase — 6 hunks, 1 mechanical, and the decisive one is delete-vs-modify on the credential entitlement path. 'Too far behind' was never the criterion; whether the conflicts are mechanical is. Also records that fork PRs run NO product CI until a maintainer approves the run, so '5 checks passing' there is no signal at all.

One minimal follow-up is now on exact head Every retry-stage entitlement refresh now re-enters turn-selection admission. During a temporary main-profile drain this keeps Exact-head Bun 1.4 validation: 109 passed, 2 platform-specific skips, 0 failed across the affected auth/routing/fallback suites; typecheck, privacy scan, and Maintainer security review and sponsorship remain required for this credential/lifecycle boundary. |

Re-verified at your new head
Verification on the merged tree (merged against current The Lab-boundary guard matters specifically here — this PR touches Why this is still not merged
I have admin merge rights and am not using them here. That gate is asking whether a human has reviewed a credential path, and "I can force it" is not an answer to that question. The So this needs @Ingwannu or another maintainer to review the auth-context/routing/core delta and sponsor it. What has changed since the review that withheld sponsorship: the branch is now current instead of 192 commits stale, and the behaviour is measured rather than assumed. |

The prior security approval applied only to e06ffba. Exact head c8556f3 adds three material routing and credential-lifecycle commits after that review, including custom canonical-forward main-profile claims, per-model detour state, preview/final quota filtering, and failing-candidate exclusion. The current diff is therefore not covered by the earlier approval.
This security-sensitive head is also 12 commits behind current dev and has intake checks only. Please rebase onto current dev and request exact-head security review. I will then trace the new claim lifetime and detour/affinity transitions through the current core and rerun the focused auth, routing, entitlement, subagent, privacy, and required CI gates. Do not merge or treat the old sponsorship as authorizing this head.

…iew gate Docs-only work-phase for a campaign whose goal is that no open pull request labeled `bug` remains on this repository. Adds the plan unit and one script. The unit records live triage of every bug PR (four parallel review lanes, each claim carrying its command and output) and the merge lane each PR belongs to: clean merge, rebase, reimplementation, or current-head re-audit. The finding that reorganized the whole campaign is that `dev` was trailing its own published channel. package.json said 2.35.0 while v2.36.0-preview.20260829 was already released, so tests/release-version-line.test.ts failed on every commit descending from dev - red inherited by six bug PRs whose own diffs never touch release tooling. Rebasing them onto an unrepaired dev could not have fixed them, so the version line became the first work-phase (#2836) and the rest of the campaign sequences behind it. scripts/ci/assert-mergeable-review.sh is the executable form of the MAINTAINERS.md approval policy. It exists because an earlier draft of this plan promised in prose not to bypass review with --admin, and prose is not a gate: the live dev ruleset has dismiss_stale_reviews_on_push false and admins can bypass pull-request requirements outright. The script exits nonzero unless one review is simultaneously the reviewer's latest state, APPROVED, bound to the exact current head, authored by someone other than the PR author, and authored by an account parsed live out of the MAINTAINERS.md maintainer table - and it refuses outright if any maintainer's latest state is CHANGES_REQUESTED. Its first version was wrong in a way worth recording (002_audit_round3_synthesis): it matched any historical APPROVED row, so a maintainer who approved a commit and then requested changes on the SAME commit still read as approval. An independent audit found it. The fix collapses history to each reviewer's latest substantive state and drops an `|| true` that had turned a failed API lookup into a verdict of "no approvals".

Summary
This is a focused follow-up to merged #2623 and #2629 for the remaining routing and lifecycle boundaries. #2509 remains closed. Distinguishing retryable roster outages from ordinary unconfirmed snapshots requires a separate multi-account and catalog policy; this PR does not claim that unimplemented 503 behavior.
