| 17 | // with no error, which is what a lapsed grant answers too: the tick |
| 18 | // then applies §2.4's transitions rather than treating it as a failure |
| 19 | // to retry on the next tick. |
| 20 | // |
| 21 | // That ended-meeting arm is belt and braces, and deliberately so |
| 22 | // (review W-5): every path that reaches a room already refuses an ended |
| 23 | // meeting earlier — roomAccess on the pages, and the stream handler |
| 24 | // which reads ended_at before it attaches, because End no longer writes |
| 25 | // a headstone for a room that was never opened. Removing it here would |
| 26 | // break nothing today and would make this function's answer depend on |
| 27 | // its callers all continuing to check first. |
