fix(ci): dispatch Strix and Noema transport continuations with the org app token - #2510
seonghobae wants to merge 3 commits into
Conversation
In consumer repositories the required Strix workflow runs with the target repository's GITHUB_TOKEN, which cannot create repository_dispatch events on ContextualWisdomLab/.github. Every provider-outage continuation therefore failed with HTTP 403 (fast-mlsirm#2031 job 109249614018, fast-mlsirm#2070 job 109233541034) and left the PR's strix check red. Outside the central repository, exchange the job's OIDC token for the OpenCode app installation token, as opencode-review.yml already does, and use it only for the dispatch POST. If no app token is available, fail without attempting the cross-repository dispatch. The live PR read and the central-repository path keep their existing token.

Merge Risk: 🔵 Low · up to The credential change prevents fallback to an unsuitable consumer token. Confirm that the selected App installation can dispatch to the central repository; otherwise continuations may still fail despite successful token exchange. No concrete serious failure is established. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The continuations gain cross-repository authority, but the implementation confines token use to a fixed dispatch request and fails closed when acquisition fails. The remaining uncertainty concerns the external exchange service’s identity checks and credential permissions, which determine whether compromise could extend beyond the intended repository.

continue-noema-transport had the same cross-repository dispatch defect as the Strix lane (#2509): in consumer repositories it POSTed the .github repository_dispatch with the target repository token. Apply the same OIDC to OpenCode app token exchange, used only for the POST, and fail without dispatching when no app token is available. The consumer-context shell tests now cover both lanes. The existing Noema contract test assumed the target token could dispatch; it now provides the OIDC and exchange fakes that the consumer path requires.

🌐 Web query:
OpenCode exchange_github_app_token endpoint implementation OIDC repository claim GitHub App installation token GitHub repository_dispatch contents write permission
💡 Result:
OpenCode’s current `dev` implementation of `POST /exchange_github_app_token`:
1. Reads a bearer token from `Authorization`; returns **401** if missing.
2. Verifies the JWT using GitHub Actions’ JWKS, issuer `https://token.actions.githubusercontent.com`, and audience `opencode-github-action`.
3. Parses the verified payload’s repository claim into owner/repo.
4. Authenticates as OpenCode’s GitHub App, looks up its installation for that repository, then returns an installation access token. Verification errors return **403**; exchange errors return **502**. ([github.com](https://github.com/anomalyco/opencode/blob/dev/packages/function/src/api.ts))
**Repository claim caveat:** the handler delegates claim parsing to `parseRepositoryClaim`; the cited file shows the call, but not that parser’s implementation. So this source alone does not establish exactly which claim formats it accepts or how it handles newer immutable `sub` formats.
**`repository_dispatch` / permissions:** this handler does not request or set token permissions or a repository scope in the shown `auth({ type: "installation", installationId })` call. Therefore, the code shown does not establish that the returned token has `contents: write`. GitHub says an installation token is limited by the app’s granted permissions, and a token can’t be granted permissions the app itself lacks. ([github.com](https://github.com/anomalyco/opencode/blob/dev/packages/function/src/api.ts)) For the `repository_dispatch` endpoint, GitHub App access requires `contents: write` (and metadata read); the OpenCode source cited here doesn’t establish whether its App has that permission. ([s.itho.me](https://s.itho.me/ccms_slides/2024/5/22/2db96ec7-bf91-4bf8-bd6e-5ffca2dfd1e9.pdf?utm_source=openai))
The source is the repository’s `dev` branch, not a specified release or commit; behavior at another version may differ.

교환된 설치 토큰의 중앙 dispatch 권한을 확인하세요.
noema-review.yml과 strix.yml은 소비자 저장소의 OIDC 토큰을 교환한 뒤, 비어 있지 않은 토큰을 ContextualWisdomLab/.github/dispatches에 바로 사용합니다. 공개 OpenCode 구현은 OIDC의 repository claim으로 설치를 선택하며 중앙 저장소를 별도로 지정하지 않습니다.
선택된 설치에 ContextualWisdomLab/.github가 포함되지 않거나 contents: write 권한이 없으면 토큰 교환은 성공해도 repository_dispatch가 실패할 수 있습니다. 실제 배포 구현과 설치 설정을 확인하고, 성공한 중앙 dispatch 기록으로 이 계약을 확인하세요.

Problem
Fixes #2509.
continue-strix-transport(added by #2479) andcontinue-noema-transport(same pattern innoema-review.yml) can never re-dispatch in consumer repositories. As an org required workflow, it runs in the target repository with that repository'sGITHUB_TOKEN;PR_REVIEW_MERGE_TOKENis not available there, soGH_TOKENfalls back togithub.token. That token cannot createrepository_dispatchevents onContextualWisdomLab/.github:ContextualWisdomLab/fast-mlsirm#2031, run 36504286670, job 109249614018:HTTP 403 Resource not accessible by integrationContextualWisdomLab/fast-mlsirm#2070, job 109233541034: same 403So every provider-outage continuation dies at the POST and the PR keeps a failed
strixcheck. The existing test only exercised the central (GITHUB_REPOSITORY=ContextualWisdomLab/.github) context, where the repository token can dispatch to its own repository.Change
Applied identically to both continuation lanes (
strix.yml,noema-review.yml):ContextualWisdomLab/.github, the step exchanges the job's OIDC token for the OpenCode app installation token (the sameexchange_github_app_tokenpathopencode-review.ymlalready uses to POSTopencode-reviewdispatches to.github), masks it, and uses it only for the dispatch POST. The job gainsid-token: write.Why the app token reaches
.github: the OpenCode API issues an installation token for the whole installation (auth({type: "installation", installationId})with no repository restriction,sst/opencodepackages/function/src/api.ts), not a token scoped to the calling repository.Evidence (local, Python 3.14)
main(POST used the target-repository token; no fail-closed path).tests/test_strix_preflight_continuation.py8 passed; the consumer-context tests are parametrized over both lanes. The existing Noema contract testtest_noema_continuation_dispatch_uses_central_handler_and_live_identityassumed the target token could dispatch cross-repository; it now supplies the OIDC and exchange fakes the consumer path requires. The new tests run the real step shell with fakegh/curl/sleepand assert the POST uses the exchanged app token, and that an empty exchange exits non-zero with no POST.git diff --checkpass.Reported independently by two sessions working on fast-mlsirm #2031 and #2070.
