SwiftUI's NavigationStack on tvOS animates pushes as a bare crossfade with no public
customization — the system Settings app slides. The home stack now applies
.customNavigationTransition(.slide) on tvOS via davdroman/swiftui-navigation-transitions
(MIT, tvOS 13+), covering the top-level routes AND the settings pickers' drill-ins.
The dependency is referenced by the Xcode PROJECT only and linked solely by the
Punktfunk-tvOS target: its manifest (no macOS platform declared vs 10.15 deps) breaks
SwiftPM whole-graph validation for plain `swift build`, and the #if os(tvOS) import
never compiles in the macOS-only SwiftPM dev shell anyway. Headless builds need
xcodebuild -skipMacroValidation (the lib pulls Swift macro packages; in the Xcode UI
it's a one-time Trust & Enable prompt).
iOS/macOS keep their untouched system navigation animations.

The same app now runs on tvOS (target Punktfunk-tvOS, bundle io.unom.punktfunk.tvos),
validated live against the box: vkcube at 1280x720@60, 60 fps in the Apple TV 4K
simulator, glass HUD with a focusable Disconnect button.
- PunktfunkCore.xcframework grows tvOS device + universal-simulator slices. These are
TIER-3 Rust targets (no prebuilt std): BUILD_TVOS=1 builds them with nightly and
-Zbuild-std from rust-src — the full quic stack (quinn/rustls-ring/tokio) compiles
for tvOS unchanged.
- The UIKit stream view covers iOS AND tvOS, with pointer interaction, pointer lock,
touch forwarding and InputCapture gated to iOS — tvOS is view-only until gamepad
capture lands (the natural tvOS input).
- SessionAudio on tvOS: .playback session, no mic (no app-accessible microphone).
- App chrome gates: keyboardShortcut/textSelection/controlSize/statusBarHidden are
iOS/macOS-only; host cards use the focus-native .card button style on tvOS; the
Audio settings section hides (system-routed); mode seeding works from the TV screen
(1920x1080@60).
- Package platforms += .tvOS(.v17); new Xcode target + shared scheme
(TARGETED_DEVICE_FAMILY 3, local-network usage description included).

Full project rename, decided 2026-06-10:
- Crates/binaries: punktfunk-core / punktfunk-host / punktfunk-client-rs.
- C ABI: punktfunk_* symbols, Punktfunk* types, include/punktfunk_core.h,
PUNKTFUNK_FEATURE_QUIC guard (header regenerated; cbindgen renames updated, incl.
PUNKTFUNK_BTN_*/PUNKTFUNK_AXIS_* wire constants).
- Protocol: punktfunk/1 — control-plane magic LMN1 → PKF1, nonce salt lmn1 → pkf1.
WIRE BREAK: clients must be rebuilt from this revision.
- Env knobs: PUNKTFUNK_VIDEO_SOURCE / PUNKTFUNK_COMPOSITOR / PUNKTFUNK_ZEROCOPY / ….
- Host config dir: ~/.config/punktfunk (the box's dir was migrated in place — the
persistent identity is unchanged, pinned fingerprints stay valid).
- Swift package: PunktfunkKit + PunktfunkCore.xcframework + PunktfunkConnection
(Sources/PunktfunkClient app + tests renamed with it); build-xcframework.sh updated.
- scripts/: 60-punktfunk.rules, punktfunk-host.service; OpenAPI doc regenerated.
Also: scripts/headless/run-headless-kde.sh — full headless Plasma bringup. Root cause of
"desktop but no apps/settings" over the stream: plasmashell launched without
XDG_MENU_PREFIX=plasma-, so the launcher resolved a nonexistent applications.menu and
rendered an empty menu. The script sets the complete KDE session env (menu prefix,
KDE_FULL_SESSION, session version) and rebuilds ksycoca before starting plasmashell.
Gate: 97/97 tests, clippy -D warnings (both feature sets), fmt, C-ABI harness PASS,
zero lumen references left outside .git.

The clients/apple scaffold is now a working macOS client, validated live against this
repo's host across the LAN: gamescope virtual output → NVENC HEVC → lumen/1 (GF(2¹⁶) FEC +
AES-GCM over UDP, QUIC control) → VideoToolbox → AVSampleBufferDisplayLayer at 720p60,
mouse/keyboard flowing back as QUIC datagrams into the host's gamescope EIS injector
(~3.7k events injected in one session).
LumenKit:
- LumenConnection: the predicted cbindgen compile fixes (C17 header spells the typedefs as
integers while the enum constants import as a distinct Swift type — bridge by rawValue);
close() is now safe from any thread (a close flag + pumpLock held across the blocking
poll enforce the C contract "never close with a next_au in flight"; flag prevents
lock-starvation by back-to-back polls).
- StreamView: per-pump cancellation token (reconnects can't double-pump), flush + re-gate
on the next in-band parameter sets when the layer fails, no stale enqueue after restart.
- InputCapture: fractional-delta accumulation (sub-pixel motion isn't truncated away),
pressed-state tracking with release-all on focus loss and stop() (nothing sticks down
host-side), global-singleton ownership guard (GC has one handler slot per process),
X1/X2 buttons, horizontal scroll, full keypad/CapsLock/ISO-102nd/PrintScreen/Menu VKs.
- LumenClient app shell (swift run LumenClient): connect form, fps/Mb-s HUD,
LUMEN_AUTOCONNECT/LUMEN_MODE for scripted first-light runs.
- Tests: Annex-B byte-level units; real-codec round trip (VTCompressionSession-encoded
HEVC rebuilt as the host's wire shape → AnnexB → VTDecompressionSession → pixels);
test-loopback.sh (Swift client vs a real local m3-host over loopback — the Swift twin of
c_abi_connection_roundtrip); RemoteFirstLightTests (full pipeline over the LAN).
Host/build fixes that fell out:
- The workspace builds on non-Linux again: gamestream audio (opus) and sendmmsg batching
are now platform-gated with stubs/fallback, per the crate's "compiles everywhere" rule.
- Horizontal scroll was inverted end-to-end: the injectors negated BOTH axes onto the
ei/wl axes, but GameStream's horizontal convention is positive = right
(moonlight-qt/Sunshine pass it through unnegated) — only vertical flips now. This also
un-inverts real Moonlight clients.
- AnnexB drops all zeros preceding a start code (trailing_zero_8bits padding), ffmpeg's
policy, instead of leaking them into the preceding NAL.
- build-xcframework.sh: deployment targets pinned to the package floor + an otool guard —
cargo does not fingerprint MACOSX_DEPLOYMENT_TARGET, so warm caches can silently ship
too-new minos objects.
Adversarially reviewed (5-dimension multi-agent pass, every finding refutation-verified):
14 confirmed findings, all fixed above; the send-while-polling core-contract gap flagged
here is closed by the lumen/1 session-planes work (&self pulls + per-plane borrow slots).

The shared-core architecture pays off: platform clients now link ONE Rust library that
does the entire lumen/1 protocol, and only add decode/present/input on top.
lumen-core:
- client.rs (quic feature): NativeClient — QUIC handshake + UDP data plane + input
datagrams on internal threads; embedder surface = connect / next_frame / send_input.
- abi.rs: lumen_connect / lumen_connection_next_au (borrow-until-next-call, matching
lumen_client_poll_frame semantics) / lumen_connection_send_input / lumen_connection_mode /
lumen_connection_close. Guarded in the generated header by LUMEN_FEATURE_QUIC (cbindgen
[defines] mapping), so the checked-in header is stable across feature sets.
- error.rs: append-only LumenStatus additions Timeout (-9) and Closed (-10).
- TESTED end-to-end through the C ABI: in-process lumen/1 host, lumen_connect pulls 25
byte-verified frames, sends input, closes (m3.rs::c_abi_connection_roundtrip).
Apple client (clients/apple — SCAFFOLD, written on Linux, first Xcode build pending):
- scripts/build-xcframework.sh: cargo per Apple target → universal staticlib + header
(LUMEN_FEATURE_QUIC pre-defined) + modulemap → LumenCore.xcframework.
- Package.swift (LumenKit) + Swift sources: LumenConnection (ABI wrapper), AnnexB
(in-band VPS/SPS/PPS → CMVideoFormatDescription, Annex-B → AVCC CMSampleBuffers with
DisplayImmediately), StreamView (SwiftUI over AVSampleBufferDisplayLayer — stage-1
presenter that hardware-decodes compressed HEVC itself), InputCapture (GCMouse raw
deltas + GCKeyboard HID→VK).
- README.md is the full handoff for the next (Mac-side) agent: build steps, ABI contract,
first-light test recipe against the Linux host, stage-2 (VT+Metal pacing) plan, and the
known host-side gaps (single-session m3-host, no lumen/1 audio yet, gamepad kinds not
yet routed in m3's injector, seed-stage trust).
