+- `.agent-context/runs/` - complete task run contexts with plan, pack, tests, impact, verify, and prompts

+## Before Closing
+- Prefer `repo-context policy . --base main --trace <trace-id>` when a trace exists.
+- Run `repo-context verify --diff .` and `repo-context loop "<task>" . --phase after-edit` before final review.
+- Check `repo-context freshness .` and `repo-context drift .` if generated context may be stale.
