- pr-review §7a: after a PR merges, recommend tearing down the worktree
and deleting the merged topic branch (local + origin) by default —
state the action, let the user decline; never touch protected branches;
git branch -d as the unmerged-work safety net.
- whats-next §3c: document the worktree lifecycle — created at activation,
removed by pr-review §7a at merge; prune stale worktrees before creating.
Closes the gap that left empty worktrees parked at main's HEAD.
