Backgrounding a live session no longer freezes it when the user opts in: audio keeps playing (UIBackgroundModes audio), the QUIC connection + pump stay live, video decode is DROPPED, and a bounded timer auto-disconnects. Off by default. - PunktfunkConnection.setVideoDropped/isVideoDropped: a tiny lock-guarded flag both pumps read every iteration. StreamPump (stage-1), Stage2Pipeline (VT + PyroWave) drain nextAU() for flow control but DISCARD the AU before any VideoToolbox/Metal work — the crash/jetsam-safe seam (no GPU off-screen). - SessionModel.enterBackground(timeoutMinutes:) / exitBackground(): set the drop flag, mute the mic (privacy — SessionAudio.setMicMuted pauses the capture engine), arm a DispatchSourceTimer that disconnect(deliberate:false)s on fire (keeps host linger → fast late reconnect). exitBackground clears the flag and requestKeyframe()s; the pump's freeze gate auto-arms on the resumed frame-index gap so concealed frames are withheld until the IDR re-anchors. disconnect() cancels the timer + clears isBackgrounded. - ContentView scenePhase driver (iOS): .background+streaming+setting → enterBackground; .active → exitBackground. scenePhase (not willResignActive) so Control-Center/app-switcher peeks don't start the timer. - Settings → General (iOS-only keepAliveSection): toggle + 1/5/10/30 timeout; new keys backgroundKeepAlive (def off) / backgroundTimeoutMinutes (def 10). - Info.plist: UIBackgroundModes [audio] + NSSupportsLiveActivities (for M3). macOS swift build + swift test green (142 tests). The iOS-gated scenePhase handler + settings section are not exercised by the macOS CI target (known §9 gap) — need on-glass verification (audio never gaps, video re-anchors <1s LAN, timeout ends the session, phone-call audio-steal degrades gracefully).

<!-- Background keep-alive (opt-in, iOS/iPadOS): the ONLY sanctioned way to keep the long-lived
