Bitbucket merges can fail with HTTP 404 before the merge request is sent because the permission check uses the retired /user/permissions/repositories endpoint. The workaround in #6525 only handles HTTP 410.

Use /user/workspaces/{workspace}/permissions/repositories, preserve the normalized full-name filter, and remove the obsolete 410 fallback. Permission decoding and merge gating stay unchanged.

Validation: 262 focused tests passed, including endpoint selection, normalized filtering, HTTP errors, permission decoding, and existing merge gating. Server typecheck, targeted lint, and formatting passed. The reporter previously confirmed the endpoint fix in an isolated UI test.

Implemented with GPT-6-Astra using the Codex harness.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This focused fix replaces a retired Bitbucket permissions endpoint and normalizes repository filters, with tests covering the changed requests and error behavior. Because the result controls repository write permissions and merge-action availability, the authorization impact requires human review.

📝 Walkthrough

Walkthrough

Repository permission checks now use Bitbucket’s workspace-scoped endpoint, filtered by the normalized workspace and repository slug. The code no longer treats HTTP 410 as permission granted. Tests cover the filter and preservation of HTTP error statuses.

Bitbucket permission flow

Workspace permission lookup

withRepository passes the workspace and slug to the permission lookup. The lookup requests workspace-scoped permissions filtered by the repository name and no longer treats HTTP 410 as permission granted. Tests cover the endpoint, filtering, and HTTP error responses. The schema comment describes the workspace-scoped response.

Merge Risk | ⚪ Minimal · up to 36c21

Merge Risk: ⚪ Minimal · up to 36c21

Bitbucket merge permission checks now use the current workspace-scoped endpoint, and failures no longer grant access. No actionable merge-blocking risk remains. CI reportedly still awaits maintainer approval to run.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 36c21

The permission lookup now targets the selected workspace and repository without broadening credential authority. Existing merge-detail loading still tolerates unreadable permissions, leaving Bitbucket as the final authority for merge requests. Remaining uncertainty concerns compatibility with the workspace endpoint, not a demonstrated new authorization bypass.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The endpoint move does not broaden the requested repository identity or configured credential privileges. The write outcome remains a merge against the selected repository and pull request under the credential selected for that request.

Trust Boundaries and Controls

  • observed — The local permission result governs offered merge actions, but the server-side merge operation does not recheck that lookup before issuing its authenticated Bitbucket POST. Unknown-permission recovery and reliance on Bitbucket's write authorization both predate this PR; neither is a newly introduced enforcement bypass.

CodeRabbit’s finding is fixed in 3a006db, its latest review reports no actionable comments, and the review thread is resolved. Local validation: 189 focused tests, targeted lint, and server typecheck passed.

The CI run for this commit is awaiting maintainer approval to execute. Could a maintainer approve it? Macroscope’s earlier approvability note requests human review of the merge-permission change; that remains for a maintainer to assess.

Include the repository identifier in the permission error.

This message identifies the operation but not the repository. When one environment serves multiple Bitbucket repositories, operators cannot identify the failed permission lookup. Pass input.repository into this error detail.

Based on learnings, failure messages must include relevant resource identifiers.

Reviewed CodeRabbit's latest review on 7412c08. No correctness findings were reported. I am deferring the optional repository-name diagnostic suggestion: the permission lookup is part of a repository-scoped PR action, and the current message preserves the operation and underlying API error. Adding resource context consistently across provider errors would be a separate diagnostics improvement.

CodeRabbit is green on the latest commit. CI is still awaiting maintainer approval: https://github.com/pingdotgg/t3code/actions/runs/35611022760. Local validation passed: production server/web build, 266 focused tests, server typecheck, targeted lint, and formatting.

Reviewed the complete diff at f902b53 with Claude Opus 5.5 via Claude Code. Final result: no actionable findings.

The reviewer initially flagged permission lookup errors blocking non-merge writes. After checking the base implementation and Atlassian’s endpoint documentation, it withdrew the finding: 403/404 and other lookup failures already propagated before this change; only the retired endpoint’s 410 was recovered. The new API-token endpoint requires repository read scope, not workspace read scope. No permission-policy expansion was added to this focused fix.

Local validation on this commit: 262 focused tests, server typecheck, targeted lint, and formatting passed. CodeRabbit is green on this commit and the prior normalization thread is resolved.

CI is awaiting maintainer approval to run.
