Requires spt-core **v0.39.1 or newer** and Oh My Pi **v16.3.15 or newer**. Update with `spt adapter update omp-spt`, then restart existing endpoints so they load the corrected extension.

### Fixed
- **Messages arriving at the end of a turn reliably wake the endpoint.** Listener delivery now delegates idle-versus-streaming arbitration atomically to OMP instead of selecting an explicit non-triggering steer from an `isIdle()` snapshot. A stream that ends between the snapshot and submission can no longer strand peer or operator messages as hidden context in the completed turn.
