 ## 5. Cleanup
 
 - [x] 5.1 Reconcile the shipped README/install docs with the zero-copy repo footprint and note any intentional compatibility leftovers. README now documents the hook-only install footprint and notes that `gx migrate` removes leftover workflow shims while the CLI still honors repo-local `scripts/review-bot-watch.sh` / `scripts/codex-agent.sh` during migration.
-- [ ] 5.2 Finish the agent branch via PR merge + cleanup (`gx finish --via-pr --wait-for-merge --cleanup` or `bash scripts/agent-branch-finish.sh --branch <agent-branch> --base <base-branch> --via-pr --wait-for-merge --cleanup`).
-- [ ] 5.3 Record PR URL + final `MERGED` evidence in the completion handoff.
