 ### Fixes
 
-- CLI/channels: preserve the first line of `openclaw channels logs` output when the rolling tail window starts exactly on a line boundary, mirroring the already-fixed `readLogSlice` behaviour in `src/logging/log-tail.ts`.

 - Control UI: treat terminal session status as authoritative over stale active-run flags so completed terminal runs stop showing abort/live UI. (#84057)
 - CLI: preserve embedded equals signs in inline root option values instead of truncating after the second separator. (#83995) Thanks @ThiagoCAltoe.
 - Matrix/config: accept `messages.queue.byChannel.matrix` queue overrides and keep queue provider schema/type keys aligned for Matrix, Google Chat, and Mattermost. Thanks @bdjben.
