+### Fixed
+- **Deferred peer deliveries now wake the receiving OMP session reliably.** Accepted messages use OMP's hidden next-turn channel with an explicit turn trigger, preserving the full SPT envelope without depending on the editable follow-up queue to resume after an active or interrupted turn.

 ## [0.3.8] - 2026-07-19
 
 > Requires spt-core **v0.31.0 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 listener and session identity.
