The room's active turn is the + current `on_message` call, not the task that made it. A cancellation already + requested when that call starts is delivered at its first step, before anything + is resolved or launched; one its caller had already received and handled does + not stop it. Retirement marks the active turn retired, so nothing it resolves + afterwards can start a process.

A turn whose deadline has + fired, or that is already handling its own outcome, keeps its timeout or other + result and its failure report. A fired deadline counts as that cancellation even + if the resolver consumed it with `uncancel()`: cleanup joins it rather than + cancelling again, and a server set the resolver returns afterwards is refused, so + the turn ends with `TimeoutError` and nothing is launched. A turn that has already + finished is never + cancelled, so its caller's later work is untouched. Retirement then waits for + that call's own finalization (not for the rest of its caller's work), and only + then closes the process and releases the workspace. A turn may request cleanup of + its own room, for example from its resolver: that call returns at once, the turn + is not cancelled again but its unfired deadline is disarmed all the same, it stops + before launching, and teardown follows its settlement. Cancelling a cleanup + call stops only that caller's wait. Until the retirement ends, turns already + waiting for the room and turns that arrive during it are cancelled rather than + starting a new process. A later turn starts normally. A room whose native close + fails keeps its process handle, overlay and exclusive workspace claim until a + later close succeeds: `on_cleanup` raises the failure, `cleanup_all` and the + room's next turn retry the close first, and the retiring process never receives + new work. +- **Permissions.** `approval_mode="yolo"` bypasses native approval checks without + changing Band platform permissions. Otherwise `resolve_permission` receives + `OmpPermissionRequest(room_id, session_id, title, options)` and returns an + offered option or `None`.
