Stream reliability
- Default to the stage-2 presenter (VTDecompressionSession + CAMetalLayer): it detects
and recovers a wedged decoder, where stage-1's AVSampleBufferDisplayLayer freezes hard
on a lost HEVC reference frame with no app-side recovery (confirmed Apple limitation).
Stage 1 is now a DEBUG-only presenter toggle, plus the automatic no-Metal fallback.
- Stage-2 pixel-perfect: render the drawable at the decoded size (shader stays 1:1 =
identity) and let the layer's contentsGravity scale via the system compositor — the
same path stage-1's videoGravity used — instead of scaling in-shader.
- Loss recovery in both pumps is now a persistent awaitingIDR want, retried until an IDR
actually lands, so a keyframe request swallowed by the throttle can't strand a frozen
frame; 100 ms keyframe throttle to match the Android path.
- Fix "Publishing changes from within view updates": defer the HostStore writes out of
the .onChange(of: model.phase) callback.
- Move AVAudioSession setActive/setCategory off the main thread (async on a shared serial
queue) to stop the UI-stall warning.
Controllers
- Rumble: capped-exponential backoff when the gamecontrollerd.haptics XPC breaks (-4811)
so a transient server interruption self-heals instead of cascading; playsHapticsOnly so
a controller engine doesn't join the always-active streaming audio session.
- Host cards: iPad pointer "magnet" hover effect; iPhone press scale + light haptic.
UI / design
- Ship Geist (SIL OFL 1.1) as the app font (bundled OTFs + registration), with the
license surfaced in Acknowledgements.
- Restructure iOS/iPadOS Settings into a category NavigationSplitView; resolution wheel
with custom-resolution entry; 10-bit HDR toggle in Display.
- Industrial host-card redesign (left-aligned, bold, brand monogram tiles).

Split the monolithic ContentView into focused view files — a pure structural refactor
with no behavior change (verified: builds macOS/iOS/tvOS, the test suite is green, and a
fidelity review against the original found no discrepancies):
- ContentView (272): the coordinator — owns the session model / host store / discovery,
switches home<->session, holds the connect logic (it reads @AppStorage) + the dev
hooks, and the stream builder (whose stable identity across awaiting-trust->streaming
must NOT move — it stays here).
- HomeView (251): the hosts grid + navigation + toolbar + sheets + "On this network"
discovery section + empty state.
- HostCards (158): HostCardView + DiscoveredCardView, sharing a CardMetrics struct
(dedupes the platform-tuned sizing the two cards had copy-pasted).
- TrustCardView (80): the TOFU prompt + fingerprint formatting.
- StreamHUDView (67): the streaming overlay HUD.
State flows idiomatically: @StateObject (ContentView) -> @ObservedObject in subviews,
@State -> @Binding; the connect logic is passed as closures. Sheet placement is
preserved — the pairing/speed-test sheets stay on the outer body so they survive the
trust->home transition.
