- ScheduledMessagesTray: cancel prunes local state ONLY on confirmed server
cancel; failures keep the item + show an inline error (was: a failed cancel
looked cancelled but still sent at the scheduled time).
- Escape semantics: the composer consumes Escape (preventDefault+stopPropagation)
iff autocomplete is open or a reply draft is set; the thread panel and Room's
markAsRead act only on unconsumed Escape, and markAsRead defers entirely while
a thread panel is open (listener order made it fire before the panel closed).
- Room: thread panel / media gallery are mutually exclusive (most-recently-
opened wins); on mobile at most one right panel renders (thread > gallery >
members) instead of stacked fullscreen overlays.
- RemindMeDialog: busy-disabled presets (no more double-click duplicates),
try/catch with inline error, close only on success.
- ThreadTimeline: "Jump to Latest" floating chip when scrolled up (RoomTimeline
idiom).
From the 4-auditor deep-audit wave; reviewer-verified.
