repo-harness-ship

# repo-harness-ship Use this command when implementation is complete and the user wants the harness to close out worktrees and create reviewable PRs. ## Protocol 1. Run worktree safety preflight with `git status --short --branch -uall` and `git worktree list --porcelain`. 2. In default PR mode, run `repo-harness run ship-worktrees`; it validates review/check evidence, runs `repo-harness run contract-worktree finish --no-merge`, pushes `codex/<slug>`, and creates a draft PR with `gh pr create --base main --head codex/<slug>`. 3. For a dirty target branch that is explicitly attributable to the active plan, pass `--slug <slug>` so the script creates `codex/<slug>-main-closeout` and opens a PR instead of committing to `main`. 4. For maintainer-only local closeout, run `repo-harness run ship-worktrees --local-merge`; this preserves the older `finish` -> fast-forward `main` -> `cleanup` path. 5. After a PR has merged and local `main` contains the branch, run `repo-harness run ship-worktrees --cleanup-merged` to remove only proven-merged local worktrees and branches. If the branch is merged but the linked worktree is dirty, pick/apply/commit useful changes first; use `--discard-scaffold-only` only when the dirty paths are generated plan/contract/review/notes scaffold. ## CHECKPOINTS - CHECKPOINT: before push, PR creation, local merge, or cleanup, verify review, external acceptance, and `verify-sprint` evidence are present and passing. ## Failure Modes - If the target worktree...
