 - Windows/restart: fall back to the installed Startup-entry launcher when the scheduled task was never registered, so `/restart` can relaunch the gateway on Windows setups where `schtasks` install fell back during onboarding. (#58943) Thanks @imechZhangLY.
 - Exec/heartbeat: use the canonical `exec-event` wake reason for `notifyOnExit` so background exec completions still trigger follow-up turns when `HEARTBEAT.md` is empty or comments-only. (#41479) Thanks @rstar327.
 - Heartbeat: skip wake delivery when the target session lane is already busy so the pending event is retried instead of getting drained too early. (#40526) Thanks @lucky7323.
+- Plugin SDK/context engines: export the missing context-engine result and subagent lifecycle types from `openclaw/plugin-sdk` so context engine plugins can type `ContextEngine` implementations without local workarounds. (#61251) Thanks @DaevMithran.
