Until now the only way to stop sending the room was to end the session and turn
"Send microphone to the host" off in Settings — a per-app setting for something
that is really a per-conversation act. The mic now mutes from inside the stream:
a button on the HUD card, the Stream menu's ⌃⌥⇧A (macOS menu bar and iPad
hardware keyboards), the same chord while input is captured (both platforms
detect it in InputCapture, where the reserved ⌃⌥⇧Q/D/S already live — ⌃⌥⇧M is
the mouse-model flip, cross-client, so the mic gets A), and on iPhone/iPad a mic
disc beside the touch exit for the stats tiers whose HUD carries no buttons.
Muting is local and instant: it gates capture on this device, the host is never
asked and never told. The muted state gets its own badge over the stream —
independent of the stats overlay, because "am I muted?" is not a statistic and
the overlay is exactly what a player turns off. The badge is also the way back:
tapping it unmutes, which is the guaranteed path for a touch user who muted with
the overlay off.
Mute is session state and is deliberately not persisted. Every stream starts live
if the mic is enabled at all, rather than carrying a mute nobody remembers making
into a call three days later.
The mechanism is the one wave 1 built. `SessionAudio.setMicMuted` — which mutes
the voice processor's input on the combined engine and pauses the capture engine
on the split one — stays the single muting path; what changes is that it now
takes an EFFECTIVE mute the session composes from its two reasons: the user's
mute and the background keep-alive's privacy mute. Neither can clear the other,
so a user who muted before pocketing their phone comes back still muted, and
backgrounding no longer un-mutes anyone on return. It also latches the state, so
a mute made while the microphone permission prompt is still open lands on the
engine that grant creates instead of being lost.
The control is offered only where there is something to mute: the session's
resolved `micEnabled` (a profile can turn the mic on or off), a platform with an
app-accessible input (never tvOS), and a TCC grant the OS hasn't refused. Absent
rather than greyed on the HUD and the touch discs, greyed on the menu, and the
macOS start-of-stream banner only teaches ⌃⌥⇧A when the session actually sends a
microphone.
