finalize-task

# Finalize task Land a task whose every `progress.md` box is checked. Two steps: prune the disposable working files, then finalize the PR. Why only `spec.md` survives — the decomposition is preserved in git history, one commit per ticket — is in [`../../tasks/concepts.md`](../../tasks/concepts.md). ## Step 1 — Prune Confirm the task is done: every box in `progress.md` is checked. If any is unchecked, stop and report which ticket is unfinished — there is nothing to land yet. Then delete the disposable files, keeping only `spec.md` in the task folder: - `tickets/` — the whole directory, review files included. - `progress.md`. - `questions.md`. - `review.md` / `review-<tag>.md`, if a task-level review ran in `md` mode. Commit the deletions on the feature branch as the task's final commit — a plain descriptive subject, the repo's `Co-Authored-By` trailer, no `#issue` reference. Pruning **before** the PR is finalized is what lets the whole-task review read the spec and the diff without any ticket files. ## Step 2 — Finalize the PR Hand off to the `create-pr` skill in **finalize-draft mode** (Mode B).
