리뷰 · 우선순위 76 / 80설명 이 PR은 라우트가 바뀐 뒤에도 호출자/프록시 admission 자격 증명이 최종 업스트림 제공자 토큰처럼 쓰이지 않게 가드를 강화한다. 작성자 luvs01, 브랜치 기준 base 문제의 핵심. keyless·non-OAuth Cursor 같은 호출자 Authorization을 업스트림으로 소비하는 전송이 있으면, OpenCodex admission bearer나 자동으로 붙인 ChatGPT main 자격 증명이 Cursor 쪽으로 새어 나갈 수 있다. 이건 #1853·#2169 credential-domain 계약의 연장이다. 재현은 “커스텀·keyless·non-OAuth” 구성이며, 일반 managed OAuth Cursor가 기본으로 뚫린다는 주장은 아니다(본문도 그렇게 한정함). 고치는 축은 (1) 게이트: Draft + 라인 - 이게 무슨 문제다 게이트 재현 범위 - 본문이 “ordinary managed OAuth Cursor는 해당 없음”이라고 한정한다. 리뷰/릴리스 노트에도 그 한정을 유지해야 한다. 그렇지 않으면 “Cursor 전부가 위험했다”로 과장되어 운영 혼란이 난다. 반대로 keyless forward Cursor를 쓰는 운영자는 지금 HEAD에서 업그레이드가 급하다는 점도 명시할 가치가 있다.
Claude 문서 표 변경 - Responses/Chat이 Dedicated+Bearer를 모두 Accept로 바꾼 locale 표는 “admission을 Bearer로도 받는다”는 기존 제품 방향과 맞지만, 업스트림으로 쓰지 않는다는 문장이 표 바로 아래에 있어야 오해가 없다. 영어본은 보강돼 있고 번역본도 같이 갔는지 확인됨(본문 기준). 좋다. 메인테이너의 판단이 필요한 지점
너의 추천 닫지 말고 스폰서 리뷰를 우선할 것. 코드 방향·회귀·Pool 재시도 sanitize는 설득력 있다. 다음 스텝: (1) 메인테이너가 auth-context·final-route strip·retry 헤더를 보안 리뷰하고 이 댓글은 grok-bot이 작성했습니다 |

In `@structure/08_openai-provider-tiers.md`:
- Around line 23-24: Update the credential-resolution guidance around the final
route to scope own-credential selection by route and account mode: allow it for
rerouted, key-auth, and noncanonical routes, while explicitly preserving
canonical openai behavior for Direct, Pool, and explicit account-qualified
sidecars.
In `@tests/codex-integration/bearer-admission-routed-provider.test.ts`:
- Line 326: Update all four no-credential cases in the bearer admission tests to
capture the request response, assert response.status is not 200, then retain the
existing capturedAuth empty assertions. Apply the same pattern to each case
consistently.
In `@tests/routing/subagent-fallback-handle-responses.test.ts`:
- Line 1877: Add an assertion after the relevant fallback/retry flow using
entitlementCalls to require more than one invocation, proving the alternate-main
retry path made a second upstream request; keep the existing final-state
assertions unchanged.

Current-head verification note: this PR now points to 3313d45. The linked successful run 34319894739 belongs to 823ab49, not this latest commit. I found no contributor Actions run for 3313d45 at the time of this check.
The latest commit changes an important legitimate path: caller Direct credentials use their own capture predicate, separate from the stricter explicit sidecar pair, and are restored only for canonical OpenAI routes. Please update the description's head/evidence and verify the current commit, including canonical reroutes with header-derived and claim-derived account identity, preserved independent caller credentials, and negative controls for noncanonical routes, proxy admission secrets and sidecar-only authority.
I am withholding approval and sponsorship pending exact-head evidence and completion of the credential-boundary review. This is a verification gap, not a claim that the new commit is defective. The earlier 26/26 run remains valid for its own head. No local live configuration, upstream credentials or running sessions were touched.
…Direct forwarding
|
@coderabbitai review Current HEAD is 6314da6. This follow-up keeps all maintainer commits through 1466e78 and changes only documentation and regression tests. The description now matches the final restore predicate and links a new full author CI run for this exact head. Local bearer-admission and subagent-fallback suites passed 84 tests with two macOS-only skips and 304 assertions. The original opaque shadow-retry rejection is preserved with and without an account header; canonical JWT-only and matching-header requests remain positive controls. Opaque/header and mismatched-account canonical reroutes are negative controls. The unchanged-Cursor case now verifies the terminal failure, and the fixture clears Combo cooldowns between cases. All eight locale pages were rebuilt and checked. Please review the current credential boundaries, including the distinction between reroute restoration, unchanged Direct forwarding and the stricter explicit sidecar pair. The PR remains Draft while current-head CI and maintainer security review/sponsorship are pending. |

There was a problem hiding this comment.
When a Chat request uses a keyless Cursor provider with its own bearer, callerAuthorizationRoute is true, so this guard skips the entire native-main claim rather than only preventing the main credential from entering the primary headers. Consequently, vision or web-search requests can no longer resolve a Direct-mode OpenAI sidecar from the stored main login, even though the Cursor bearer and stored OpenAI credential now have separate request-local destinations. Claim and snapshot the stored main credential into openAiSidecarAuth for this case while continuing to withhold it from headers.

Confirmed and reproduced against the maintainer carry #4102: the owned-main sidecar case fails before the fix, while the ownership-fenced control passes. The minimal correction and wire regressions are in child #4103 (135df73), targeting the carry branch; 143 affected tests and static checks passed. This source branch remains held to avoid competing changes. Leaving this thread open until the carry integrates the correction.

…-carry fix(auth): keep credentials scoped to the final routed provider (carry of #4081)
|
Superseded by maintainer carry #4102, now merged into dev at 4de1ecc. The landed head 4a201df includes the original attributed carry, subsequent boundary corrections, and the reviewed #4103 sidecar follow-up. Exact-head contributor CI 34339651388 passed 26/26 jobs; Ingwannu approved that same combined head. The parent verified dev ancestry and the merge tree. Final cumulative dev validation is still pending and is not claimed by this closure. Thank you for the original implementation and follow-up regressions. |

Summary
Maintainer carry: #4102. This source branch is held at
630d4fe23628bc959892c5e5ea70b96c89d253ce; follow-up integration is tracked on the carry. This PR stays open until that carry lands. The newly identified stored-sidecar Chat regression is being handled against the carry, so this draft is not being promoted separately.Keep proxy admission, caller authentication and provider credentials separate when a request changes routes. A keyless, non-OAuth Cursor route can otherwise consume an OpenCodex admission bearer or automatically added ChatGPT main credential as its own upstream token.
Resolve credentials for the final transport, strip proxy secrets regardless of the admission header used, and retain sanitized caller input through alternate-account retries. Claude replay retains its claimed main credential only in memory and reconstructs it only for the final canonical ChatGPT route. An unchanged thread marker, an independent Cursor bearer, configured provider keys and normal native substitution remain supported.
Canonical OpenAI reroutes may restore a single non-proxy bearer only when its JWT carries a ChatGPT account claim and any explicit account header matches it. An opaque bearer is not restored across a rewrite even when it includes an account header. This is deliberately stricter than unchanged-route Direct forwarding. JWT claims are routing evidence, not signature verification; the upstream validates the credential.
Optional OpenAI sidecars keep a separate caller-auth snapshot that additionally requires a matching explicit account header. Stored-account and Pool sidecar authentication retain their existing rules. Noncanonical caller-auth transports withhold ChatGPT-domain bearers, combined/malformed Authorization values, proxy secrets and the ChatGPT account header.
This continues the credential-domain contract in #1853 and #2169. The directly reproduced configuration is custom, keyless and non-OAuth; it is not a claim about ordinary managed OAuth Cursor configurations or an unauthenticated caller choosing an arbitrary receiver. The maintainer security review is recorded below.
