 ### Fixes
 
+- Heartbeat/Cron: restore interval heartbeat behavior so missing `HEARTBEAT.md` no longer suppresses runs (only effectively empty files skip), preserving prompt-driven and tagged-cron execution paths.
 - Gateway/Pairing: tolerate legacy paired devices missing `roles`/`scopes` metadata in websocket upgrade checks and backfill metadata on reconnect. (#21447, fixes #21236) Thanks @joshavant.
 - Docker: pin base images to SHA256 digests in Docker builds to prevent mutable tag drift. (#7734) Thanks @coygeek.
 - Provider/HTTP: treat HTTP 503 as failover-eligible for LLM provider errors. (#21086) Thanks @Protocol-zero-0.
