    Idle time does NOT gate this verdict — a recap that ends with "want me to…?" is awaiting you whether it landed 10 seconds or 10 hours ago. Do NOT downgrade a fresh awaiting-review recap to `active` just because `last_turn_age_sec` is small; the agent has stopped and will not move without you.

    **B1 vs B2 (cleanup vs awaiting-review) — the dividing line:** cleanup is for work that is *finished and disposable* — the deliverable was an action already taken (probe ran, PR merged, test executed) and nothing is left to look at. Awaiting-review is for work whose *deliverable is a thing you must still consume or authorize*. When a recap says "done" AND names something for you to read/decide/approve/activate/merge, it is B2 (`needs_user`), not B1. When in doubt between cleanup and awaiting-review, choose `needs_user` — an extra card is cheap; a wrongly-sent `/cleanup` destroys the deliverable.
