Most modals rendered a folds Dialog/Modal with no role and no name, and
their focus traps used `initialFocus: false`, so focus stayed behind the
modal and a screen reader never announced it.
- 32 dialogs with a visible heading: role="dialog", aria-modal,
aria-labelledby → the heading (given an id), tabIndex=-1.
- 4 dialogs that already had a name (Leave Room, room topic viewer,
server ACL, room-nav prompt): role + aria-modal.
- Their focus traps drop `initialFocus: false` for focus-trap's default
(keep an already-focused autoFocus field, else the first tabbable
element) with the dialog itself as fallbackFocus, so a dialog without
a tabbable node can't crash the trap. Traps that live in a parent
(UIA stages, Logout, Forward, Invite) get the semantics only.
- The file drop overlay is deliberately left alone (not a dialog).
Checked at runtime: Join with Address, Delete Message, Report Message,
Leave Room and Logout open as named dialogs with focus inside and close
with Escape (Tab first when a text field has focus — the shared
stopPropagation keeps Escape from discarding typed text, by design).
The axe e2e spec (6 tests) passes; eslint warnings unchanged (46).
17 modals with no heading (image/file viewers, loading screens) remain.

Room Settings → General → Privacy: 'Your messages in this room' with a
Delete all… flow. The confirm dialog first counts your events with a
server-side sender-filtered /messages walk (live count), then asks to confirm
with the number — typing the room name above 50 — and offers 'Leave the room
afterwards'. Files are called out as not purged by a redaction.
The job runs outside React (closing settings is fine): sequential redactEvent
with 429 back-off, 404/already-redacted skipped, progress on the tile with
Cancel, pending ids persisted per room so a reload shows Resume/Discard, a
toast when done. State events are never touched; reactions, edits and thread
replies you sent are included; encrypted rooms work the same (nothing is
decrypted). Own events need no power level, so it is purely self-service.
Unit tests cover candidate filtering, the server filter, pagination, 429/404
handling and cancel. Verified headless: 62 of bob's events (60 messages, a
reaction, a thread reply) redacted in ~34 s while alice's 10 stayed; cancel at
17/40 → reload → Resume → 'Deleted 40 messages.'
