Lands the audit follow-ups that didn't require external input. Only the wire-format draft pinning (MoQ #1, #8) remains deferred — that's gated on the M4 manual interop pass, and the same-room-PIP-re-entry corner case (Android #5) — Android has no programmatic PIP-exit API. ViewModel: - VM #10: serialize disconnect→connect via a tracked `pendingCloseJob`. teardown() records the listener.close() launch (when not finalCleanup); the next launchConnect() awaits it before opening a fresh transport. Eliminates the brief two-QUIC-session overlap that some MoQ relays reject by deduping on client pubkey. - VM #4: extracted shared connect-launch body into `launchConnect(triggerRetryOnFailure)` so connect() / connectInternal() share one implementation. Removed the near-duplicate viewModelScope.launch block. - VM #8b: setMicMuted no longer silently swallows handle failures. BroadcastUiState.Broadcasting gains a `muteError: String?` field that the UI can surface as an inline message; cleared on the next successful toggle. The broadcast itself stays running with its previous mute state — only the mute toggle failed. - VM #6: documented the dispatcher-confinement contract in the class kdoc. Audit was theoretical — every map mutation already runs on viewModelScope (Dispatchers.Main.immediate on Android, same dispatcher the MoQ flow's onEach callback uses because the player launch lives in viewModelScope). Future cross-thread callers must marshal explicitly. Android: - Android #2: AudioRoomActivity.toggleMuteSignal type tightened from `MutableSharedFlow<Unit>` to `SharedFlow<Unit>` so external code can't tryEmit into it. Internal emit uses the private `_toggleMuteSignal`. - Android #10: presence debounce-publisher (the LaunchedEffect keyed on micMutedTag) now skips entirely when micMutedTag is null. Stops the duplicate first-frame publish where heartbeat fires immediately AND debounce-publisher fires 500 ms later, both with muted=null. Once the user goes live the debounce-publisher kicks in for state changes. MoQ session: - MoQ #11: send() rollback comment rewritten to say "monotonic; gaps acceptable per spec, this just minimises them on full-fanout failures" instead of the misleading "strictly contiguous" claim. Verified: spotlessApply clean; :commons:jvmTest, :nestsClient:jvmTest (80 tests), :amethyst:compilePlayDebugKotlin all green. Still deferred: - MoQ #1, #8: wire-format draft pinning (draft-17 vs draft-11). Needs M4 interop input from `nostrnests.com` to know what the relay actually speaks. - Android #5: same-room re-entry from MainActivity while in PIP doesn't auto-exit PIP. Android has no programmatic PIP-exit API; user must tap the expand button. Corner case. - Test coverage gaps (round-1 VM #10, round-2 VM #13): retry-counter + broadcast state + setMicMuted-no-handle + server-Closed cleanup + double-connect-while-Failed. Each is a small dedicated test using the existing connector-seam pattern; landing as a separate test-only commit.
