- 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.

Right-side thread drawer (MembersDrawer pattern; mobile fullscreen):
- ThreadPanel: header + close/Escape, ThreadTimeline, its own RoomInput
(threadRootId prop; drafts/replies/uploads isolated per roomId::threadId;
schedule + slash-commands off in threads v1) and threaded mark-as-read.
- ThreadTimeline: lean reimplementation over thread.liveTimeline — copied
useTimelinePagination pattern (/relations back-pagination + decryption),
virtualized, root event emphasized + "N replies" divider, reactions/edits/
redactions, and a pending strip (chronological local echo never enters the
thread timelineSet — rendered from LocalEchoUpdated instead).
- ThreadSummary chips on root messages (server-aggregated bundle or live
Thread; unread badge via getThreadUnreadNotificationCount) keep threads
discoverable now that replies leave the main timeline.
- Reply-in-Thread menu + thread indicators open the panel; deep links to
thread events redirect into it.
- State: roomIdToActiveThreadIdAtomFamily + getThreadDraftKey (+18 tests).
Gates: tsc clean, eslint 0 errors, build OK, 616/617 tests (1 IDB skip).
Awaiting live QA; release note: threaded replies no longer render inline.
