Finish PR

Bring an existing pull request to a current-head state that is reviewable or mergeable. This is a convergence workflow: repeat review and validation until a terminal condition is reached.

1. Establish Authority and Isolation

Resolve the PR, repository, branch, current head SHA, base branch, draft state, required checks, review state, and applicable repository instructions. Work from a clean isolated checkout of the PR head. Preserve unrelated changes.

Rebase or restack according to repository policy before trusting results. Review conflict resolutions and push safely. Preserve an explicit draft state unless the user asks to mark the PR ready.

Merge, admin merge, deployment, and protection bypass each require explicit user authority. A request to finish review does not imply any of them.

2. Review Independently

Inspect the complete semantic diff against the correct base and fix confirmed defects. Run proportionate focused checks, then the repository's canonical CI-equivalent verification when practical. Treat generated artifacts by their canonical source and check the generated delta for drift.

3. Converge Reviews and CI

Run /rabbit-round for the current head. Push accepted fixes before replying to review threads. Then refresh reviews and required checks for the new head.

When bots or CI are still running, use the environment's monitor or wait mechanism; do not occupy the shell with sleep polling. Repeat only when new evidence arrives: a completed check, new review, new commit, or changed thread state.

Investigate failures from their logs and fix causes within scope. Do not rerun a failed job repeatedly without a reason, weaken checks, reseed baselines, dismiss valid reviews, or bypass protections merely to make the PR green.

4. Stop at a Real Terminal State

The latest pushed head has converged only when:

• required CI is green
• automated reviewers are terminal, not pending
• no actionable bot thread remains unresolved
• no unresolved human request for changes remains
• no blocking review or merge conflict remains

If convergence requires a user decision, new authority, unavailable credentials, or an external state change, report the exact blocker and the evidence already collected.

Merge only when explicitly requested. Use the requested normal or admin path, and never use admin authority to bypass a correctness failure. After any authorized merge, verify the PR state and report the resulting commit.

Report the PR URL, latest head, review and CI state, changes made, validation run, and whether the terminal state is ready, merged, or blocked.
