Missing or + failed receipts fail startup rather than allowing a model to answer without its + required tools. Native connection and tool failures remain errors, not successful + Band replies. The enclosing turn timeout still bounds startup. +- **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`. Unknown or unoffered choices cancel the request. + Without a resolver, only the exact native `("Approve", "Deny")` select is + approved.

Every agent API response already carries X-API-Version, so the activity POST itself now teaches the process whether detail is supported. This removes the discovery GET, its rest_url plumbing, the half-budget split and the cross-loop owner/waiter coordination. The 422 downgrade now logs the room and body, and an unadvertised version is logged at debug.

latch activity detail off for the whole process.

Hook the typed activity helpers into the existing toolCallId-correlated tool events and around the permission resolver wait: a running tool reports its name, a /approve or human wait reports permission, and everything returns to reasoning as they finish. Names pass through unfiltered here; the SimpleAdapter chokepoint gates them on the same Tool calls & results choice as tool narration, so a tool-reporting-off agent leaks no names and no argument text ever reaches the reporter. Guarded by tests/adapters/test_omp_activity.py, driving start/end and the approval wait with narration on and off.
