 ### Changes
 
+- iOS/Watch: add an Apple Watch companion MVP with watch inbox UI, watch notification relay handling, and gateway command surfaces for watch status/send flows. (#20054) Thanks @mbelinky.
 - Gateway/CLI: add paired-device hygiene flows with `device.pair.remove`, plus `openclaw devices remove` and guarded `openclaw devices clear --yes [--pending]` commands for removing paired entries and optionally rejecting pending requests. (#20057) Thanks @mbelinky.
