MobileChatScreen DM header now applies parseFederatedUsername and
useCanonicalUserView, matching MobileDmsScreen so federated users render
as 'realname' rather than 'realname@domain'.
Mobile Voice & Audio renamed to Voice & Video across MobileSettingsScreen
and MobileYouScreen — parity with desktop's VoicePanel title.
AudioInputSection and VideoSection picker click-outside now listens for
touchstart alongside mousedown so a single tap dismisses on iOS Safari
(which doesn't synthesize mousedown reliably from touch).
AudioOutputSection feature-detects HTMLMediaElement.setSinkId at module
load and returns null on unsupported platforms (notably iOS Safari).
Split into outer gate + inner body to keep Rules of Hooks intact;
VoicePanel's space-y-5 collapses cleanly with no visible hole.
VideoSection 'Stop preview' CTA gets responsive sizing (mobile:
always-visible 44 px tap target; desktop: original hover-reveal pill via
md: prefixes). The preview <video> gains autoPlay so iOS Safari starts
the stream when srcObject is assigned — manual videoEl.play() after an
awaited getUserMedia loses the user-gesture context on iOS and was
silently rejected by .catch(()=>{}), causing the black-preview bug.
voice.md updated for the iOS hide-when-unsupported policy and the
touch-close contract on device pickers.
Chromium gates the PulseAudio loopback path behind the
PulseaudioLoopbackForScreenShare feature flag. Without it, returning
audio: 'loopback' from setDisplayMediaRequestHandler rejects the whole
getDisplayMedia request, so screen share never starts when the user has
"Share system audio" enabled. Also surface a clear warning toast on
loopback failure (PipeWire-only without pulse compat, macOS without
Catap) instead of failing silently — no auto-retry, since the picker
selection is already consumed.
requestFullscreen() on the voice container puts only its descendants in the
browser's top layer; overlays portaled to document.body were rendered outside
that layer and stayed invisible — most visibly the right-click context menu on
stream tiles and voice user panels.
Add usePortalContainer() hook returning document.fullscreenElement ?? document.body
and re-rendering on fullscreenchange. Migrate every overlay reachable during a
call: ContextMenuRenderer (desktop, submenu, mobile sheet), Tooltip,
ConfirmDialog, ConnectionInfoPopover, ScreenShareSettingsPopover, and
ScreenSharePicker (which previously rendered inline at App root).
federation.md — new undeliverable bucket subsection with three-way
classification table, Path A/B semantics, and wire backward-compat note.
voice.md — no_recipient row in failure-surface table.
websocket.md — DmCallUndeliverableReason union updated to include no_recipient.
dm-system.md — cross-reference to voice.md for no_recipient reason.
