chore(release): bump workspace version to 0.8.0

The [workspace.package] version (inherited by every crate via version.workspace)
is the release being cut; refresh the 9 workspace entries in Cargo.lock to match
(CI builds --locked). Canary derives from the tag (scripts/ci/pf-version.sh), so
cutting v0.8.0 auto-advances canary to 0.9.0.

-# CLAUDE.md — punktfunk
-
-Low-latency desktop/game streaming stack, Linux-first, with a shared Rust protocol core
-(`punktfunk-core`) exposed over a C ABI and native clients per platform. Full design:
-[`design/implementation-plan.md`](design/implementation-plan.md). Status table: `README.md`.
-
-## Where the work stands
-
-- **Core (`punktfunk-core` + C ABI): complete and hardened.** FEC recovery, loopback-under-loss,
-  proptests, C ABI harness all green; 13 adversarial-review findings fixed +
-  regression-tested (`a913042`).
-- **GameStream host: working end-to-end with a stock Moonlight client.** Validated live
-  on this box: pairing (persists across restarts), serverinfo/applist (app catalog from
-  `~/.config/punktfunk/apps.json` → each entry picks a compositor + nested command), RTSP, ENet
-  control, audio, and video at the **client's native resolution and refresh** — the host
-  creates a per-session virtual output via per-compositor `VirtualDisplay` backends:
-  **KWin** (`zkde_screencast stream_virtual_output`, needs KWin ≥ 6.5.6 headless; >60 Hz via
-  custom modes), **gamescope** (spawned headless at WxH@Hz, its PipeWire node captured, needs
-  gamescope ≥ 3.16.22 — older deadlocks on PipeWire ≥ 1.6), **Mutter** (D-Bus
-  `RecordVirtual` virtual monitor; validated live on headless GNOME Shell 50, zero-copy),
-  **Sway/wlroots** (`swaymsg create_output` + custom mode, xdpw portal capture with a
-  managed chooser config; validated live on sway 1.11, zero-copy).
-  Performance work landed and measured: GPU **zero-copy** on all paths (tiled dmabuf →
-  EGL/GL → CUDA; LINEAR dmabuf → **Vulkan bridge** → CUDA → NVENC), auto 2-way NVENC
-  split-encode above ~1 Gpix/s (5K@240), infinite GOP + RFI keyframes (killed the periodic
-  freeze), encode|send thread split with `sendmmsg` batching. Stable 240 fps at 5120×1440.
-  Input: mouse/keyboard (libei via RemoteDesktop portal on KWin/GNOME, gamescope's own EIS
-  socket, wlr protocols on Sway) and **gamepads** (uinput X-Box-360 pads + rumble
-  back-channel; validated live — pad created/destroyed with the session). Management REST API +
-  checked-in OpenAPI doc (`mgmt.rs`). **Web-console performance capture** (`stats_recorder.rs`,
-  design: [`design/stats-capture-plan.md`](design/stats-capture-plan.md)): the operator arms stats
-  recording from the web console, plays, stops, and reviews the run as graphs (per-stage latency
-  breakdown · fps new/repeat · goodput · loss/FEC). A shared `Arc<StatsRecorder>` ring (the hot-path
-  gate is a runtime `AtomicBool`, replacing the startup-only `PUNKTFUNK_PERF`) is fed by **both** the
-  native `virtual_stream` and the GameStream encode loop at their existing ~2 s/~1 s aggregation
-  boundary, and finished captures are saved as on-disk recordings
-  (`~/.config/punktfunk/captures/*.json`) browsable/exportable from the console's **Performance** page
-  (recharts). Endpoints `/api/v1/stats/*` (bearer-only). *Implemented; not yet on-glass validated.*
-- **Native protocol (`punktfunk/1`): full session planes, validated live.** QUIC
-  control plane (`punktfunk-core` `quic` feature: Hello{mode}/Welcome{full Config}/Start), data
-  plane = the hardened core `Session` over raw UDP with **GF(2¹⁶) Leopard FEC + AES-GCM**
-  (inexpressible in GameStream), host creates the native virtual output at the client's
-  requested mode. `punktfunk1-host` is a **persistent listener** (sessions back to back;
-  `--max-sessions`). QUIC datagrams carry the side planes, demuxed by first byte: input
-  0xC8 (incl. **gamepads** — incremental events accumulated into the uinput xpad), **Opus
-  audio** 0xC9 (48 kHz stereo, 5 ms, host→client), **rumble** 0xCA (host→client). **Trust:**
-  host serves its persistent identity (`~/.config/punktfunk/cert.pem`, shared with GameStream
-  pairing) and logs the SHA-256 fingerprint; clients pin it, established by a **SPAKE2 PIN pairing
-  ceremony** (host arms pairing and displays a 4-digit PIN; a PAKE binds both cert fingerprints so an
-  attacker gets one online guess, no offline dictionary attack) — PIN pairing is the default for new
-  hosts. **TOFU on first connect** (`endpoint::client_pinned`) stays as an explicit host opt-in
-  (`punktfunk1-host --allow-tofu` / `serve --open`, advertised as `pair=optional`) for fully trusted LANs;
-  clients only offer the TOFU "Trust" path for a host that advertised `pair=optional`, route every
-  other new host straight to the PIN ceremony, and on a pinned-fingerprint change force re-pairing
-  (no re-TOFU shortcut). Clients present persistent identities via QUIC client auth, the host stores
-  paired fingerprints (`punktfunk1-paired.json`) and gates sessions with `--require-pairing` (the
-  default; `--allow-tofu`/`--open` accept unpaired clients).
-  **LAN auto-discovery**: both `serve` and `punktfunk1-host` advertise the native service over
-  mDNS (`_punktfunk._udp`, `crate::discovery`) with TXT `proto`/`fp`(cert fingerprint to
-  pin)/`pair`(required|optional)/`id`; `punktfunk-probe --discover` lists hosts, Apple clients
-  browse the same service via NWBrowser (validated cross-LAN 2026-06-12).
-  **Mid-stream mode renegotiation**: `Reconfigure` on the still-open control stream — the
-  host rebuilds output+encoder at the new mode in ~90 ms while the data plane runs on
-  (validated live: one .h265 with 720p and 1080p segments). Measured on-box at 720p120: 1680/1680 frames, **p50 0.83 ms**
-  capture→…→reassembled; audio measured live (~200 pkts/s). A **wall-clock skew handshake**
-  (`ClockProbe`/`ClockEcho`, 8 NTP rounds after `Start`, `clock_offset_ns`) aligns the client to the
-  host clock, so that latency is now valid **cross-machine** (`skew_corrected=true`) — measured GNOME
-  box → dev box over the LAN: **p50 1.30 ms** (the −1.57 ms inter-box clock offset removed).
-  `punktfunk-probe` is the
-  working reference client (`--pin`, datagram counters, `--input-test` incl. gamepad).
-  The embeddable connector (`NativeClient`) exposes it all over the C ABI: `punktfunk_connect`
-  (pin/TOFU) + `next_au`/`next_audio`/`next_rumble`/`next_hidout`/`send_input`/
-  `send_rich_input`. **Client-negotiated virtual pad type**: the Hello carries a gamepad
-  preference byte (same trailing-byte back-compat pattern as the compositor), the Welcome
-  echoes the resolved backend — precedence: explicit client choice > `PUNKTFUNK_GAMEPAD`
-  env > uinput Xbox 360. Backends: **Xbox 360** (uinput / ViGEm), **Xbox One/Series** (the same
-  XInput backend with the One/Series USB identity for matching glyphs — no extra game-visible
-  capability; impulse-trigger rumble is unreachable through a virtual pad), and the UHID
-  `hid-playstation` pads — **DualSense** (adaptive triggers, lightbar, touchpad, motion) and
-  **DualShock 4** (lightbar, touchpad, motion, rumble; DualSense minus adaptive triggers / player
-  LEDs / mute). DualSense and DualShock 4 each have a Linux (UHID `hid-playstation`) **and a Windows
-  (UMDF minidriver)** backend — `inject/dualsense_windows.rs` + `inject/dualshock4_windows.rs`, one
-  driver serving either identity per a `device_type` byte the host stamps into shared memory (the DS4
-  reuses the same SwDeviceCreate game-detection identity fix as the DualSense). One/Series stays
-  Linux-only and folds into Xbox 360 off it. Clients auto-resolve the type from the physical controller
-  (DS5→DualSense, DS4→DualShock 4, Xbox One→Xbox One). **Windows uses ZERO external gamepad
-  dependencies — ViGEmBus is gone.** Xbox 360 (XInput) runs on a UMDF2 **XUSB companion** driver
-  (`packaging/windows/xusb-driver/`, `inject/gamepad_windows.rs`) that registers `GUID_DEVINTERFACE_XUSB`
-  and answers the buffered XInput IOCTLs from a shared section, so classic `XInputGetState`/`SetState`
-  work with no kernel bus driver (validated live: slot connected, state + rumble round-trip; Xbox One
-  folds to this 360 path). All three UMDF drivers (DualSense/DS4 + XUSB) are bundled + pnputil-installed
-  by the Inno Setup installer (`packaging/windows/gamepad-drivers/` + `install-gamepad-drivers.ps1`).
-  **Multi-pad ready**: the host stamps each pad's index into the device Location (`pszDeviceLocation`),
-  the driver reads it (`WdfDeviceAllocAndQueryProperty`) to map its own `*-shm-<index>`, and
-  `UmdfHostProcessSharing=ProcessSharingDisabled` gives each pad its own host (per-pad statics) —
-  validated live with 2 distinct XInput slots + 2 DualSense pads. (Client-side multi-pad forwarding is
-  the remaining piece.)
-- **Windows host: implemented and shipping (all-vendor, x64-only).** `#[cfg(windows)]` backends
-  behind the same traits as Linux — DXGI Desktop Duplication capture (`capture/dxgi.rs`), **SudoVDA**
-  virtual display per session (`vdisplay/sudovda.rs`), GPU encode (NVENC `--features nvenc`; AMD/Intel
-  `--features amf-qsv`), SendInput + **ViGEm** gamepads (`inject/gamepad_windows.rs`), WASAPI loopback
-  + virtual mic (`audio/wasapi_*`). Ships as a **signed Inno Setup installer** that registers a
-  `LocalSystem` SCM service launching into the interactive session for secure-desktop (UAC/lock-screen)
-  capture (`service.rs`), bundles the SudoVDA driver + the FFmpeg DLLs, and is published by
-  `windows-host.yml`. **Encoder is GPU-aware** (`encode.rs` `open_video` + `windows_resolved_backend`):
-  `PUNKTFUNK_ENCODER=auto` (the host.env default) detects the DXGI adapter vendor → **NVENC** (NVIDIA,
-  direct SDK, `encode/nvenc.rs`), **AMF** (AMD) / **QSV** (Intel) via libavcodec
-  (`encode/ffmpeg_win.rs`, the Windows analogue of the Linux VAAPI backend — `WinVendor{Amf,Qsv}`,
-  system-memory NV12/P010 readback default + opt-in zero-copy D3D11 behind `PUNKTFUNK_ZEROCOPY` with a
-  system fallback), or software H.264 (`encode/sw.rs`, GPU-less). GameStream codec advertisement is
-  probed per-GPU on AMF/QSV (`windows_codec_support` → `serverinfo`, AV1 gated). **HDR (10-bit)**: WGC
-  captures the HDR desktop as FP16/Rgb10a2 (DDA FP16 for the secure desktop), the encoder forces HEVC
-  Main10 + BT.2020 PQ (NVENC ABGR10/P010; AMF/QSV P010 + a swscale Rgb10a2→P010 fallback), the client
-  auto-detects PQ from the HEVC VUI — gated by `PUNKTFUNK_10BIT` + client `VIDEO_CAP_10BIT`; **Windows
-  host only** (the Linux host stays 8-bit, blocked upstream). **Vulkan-game HDR over the virtual
-  display**: NVIDIA/AMD Vulkan ICDs refuse to *advertise* an HDR color space for a surface on an IddCx
-  indirect display (so Vulkan games — Doom: The Dark Ages, id Tech, etc. — say "device does not support
-  HDR"), even though the ICD happily *accepts + presents* a forced HDR swapchain there. A tiny always-on
-  Vulkan **implicit layer** (`packaging/windows/pf-vkhdr-layer/`, `VK_LAYER_PUNKTFUNK_hdr_inject`)
-  injects the `HDR10_ST2084`/scRGB surface formats into `vkGetPhysicalDeviceSurfaceFormats[2]KHR`,
-  self-gated on the display's actual advanced-color state (no-op on SDR / real monitors); bundled +
-  HKLM-registered by the installer. **Live-validated: Doom: The Dark Ages enables HDR over the virtual
-  display.** **AMF/QSV is CI-green but not yet on-glass validated** (no AMD/Intel Windows box in the
-  lab); NVENC is live-validated. Newer/less battle-tested than the Linux host. Packaging: `packaging/windows/`.

-## What's left
-
-1. **Native clients — decode + present: macOS stage 1 done, first light achieved
-   (2026-06-10).** PunktfunkKit compiles and is tested on macOS (AnnexB → VideoToolbox →
-   `AVSampleBufferDisplayLayer`, GCMouse/GCKeyboard capture, `PunktfunkClient` app shell);
-   validated live Mac ↔ this box at 720p60 — vkcube on glass, input injected via gamescope
-   EIS. The app speaks the full ABI v2 trust surface: Keychain-persisted client identity
-   presented on every connect, SPAKE2 PIN pairing UI (host-card context menu + the trust
-   prompt's "Pair with PIN instead…"), TOFU fingerprint prompt. **Gamepads (2026-06-11):**
-   controller discovery + selection in Settings (`GamepadManager` — exactly one pad
-   forwarded as pad 0, auto or pinned; pad TYPE auto-resolves from the physical
-   controller, user-overridable), capture incl. DualSense touchpad/motion
-   (`GamepadCapture`/`GamepadWire`), feedback rendering (rumble → CoreHaptics; lightbar /
-   player LEDs / adaptive triggers → `GCDeviceLight`/`playerIndex`/
-   `GCDualSenseAdaptiveTrigger` via the table-driven `DualSenseTriggerEffect` parser).
-   Loopback-tested end to end (`PUNKTFUNK_TEST_FEEDBACK=1` scripted burst); DualSense
-   motion sign/scale derived, not yet live-verified. Tests: `swift test` in
-   `clients/apple` (unit + real-codec round trip),
-   `test-loopback.sh` (Swift client vs synthetic punktfunk1-hosts on loopback — runs on macOS;
-   includes the pairing ceremony + `--require-pairing` gate),
-   `RemoteFirstLightTests` (full pipeline over the LAN). See
-   [`clients/apple/README.md`](clients/apple/README.md). **Stage 2 presenter is now the DEFAULT**
-   (stage-1 is the Metal-unavailable / DEBUG fallback): explicit `VTDecompressionSession` decode →
-   `CAMetalLayer`, presented from the hosting view's **main-runloop `CADisplayLink`** (`renderTick` pops
-   the newest ready frame per vsync; macOS `displaySyncEnabled = false` is the real fullscreen-judder fix,
-   ~11 ms p50). *(An off-main `CAMetalDisplayLink` and an off-main blocking-render present thread were
-   both tried and reverted — both measured slower on macOS and iPad.)* **HDR fixed**
-   (`design/apple-stage2-presenter.md`): the "too bright" bug was a missing reference-white anchor — the
-   fix keeps the PQ-passthrough shader and adds `CAEDRMetadata.hdr10(…, opticalOutputScale: 203)` +
-   `wantsExtendedDynamicRangeContent` on the layer (on all platforms; the old `#if os(macOS)` guard left
-   iOS/tvOS EDR half-engaged), routing the 0xCE mastering metadata to the layer (via `setHdrMeta`) instead
-   of a never-composited source buffer. **Mid-session SDR↔HDR** is handled: `render` reconciles the layer
-   per-frame from the decoded `frame.isHDR` (per-mode pixel format `bgra8`/`rgba16Float`), so a game
-   entering HDR mid-stream just reconfigures (last 0xCE grade cached + re-applied; pump drains 0xCE
-   unconditionally). **4:4:4 added**: decode format is a 2×2 `(chroma, HDR)` matrix
-   (`420v/x420/444v/x444`, all biplanar so the shaders are unchanged), advertised (`VIDEO_CAP_444`) only
-   behind a **hardware-required `VTDecompressionSession` probe** (`Stage444Probe`, validated on M3) with a
-   Settings opt-out + a bounded pump backstop for an undecodable 4:4:4 session. *HDR brightness + 4:4:4
-   still need on-glass validation (Windows-HDR / `PUNKTFUNK_444` host).* Next: glass-to-glass numbers via
-   `tools/latency-probe`.
-   **Linux stage 1 done, first light 2026-06-12** (`clients/linux`, binary
-   `punktfunk-client`): GTK4/libadwaita shell linking `punktfunk-core` directly (no C ABI;
-   `NativeClient` is now `Sync` — mutexed plane receivers), mDNS host list, TOFU + SPAKE2
-   PIN dialogs (identity shared with client-rs), FFmpeg software HEVC decode (LOW_DELAY,
-   slice threads) → `GtkGraphicsOffload`-wrapped picture, PipeWire playback (mic-player
-   jitter ring inverted), SDL3 gamepad capture + rumble/lightbar feedback, keyboard via
-   exact inverse of the host VK table, absolute mouse + 120-unit scroll. Validated live
-   against `serve` on this box: 1080p60, steady 60 fps, capture→decoded p50
-   ≈6.4 ms (debug build). `--connect host[:port]` for scripting. **Swift-parity batch +
-   stage 1.5 (2026-06-12 evening)**: capture state machine (click-to-capture,
-   Ctrl+Alt+Shift+Q / focus-loss release, held-state flush), app-lifetime SDL gamepad
-   service (pad pin UI, auto type from the physical pad, DualSense touchpad/motion 0xCC +
-   raw-DS5-effects trigger/player-LED replay — needs a physical pad to live-verify), mic
-   uplink (validated live), per-host speed test, compositor pref, native-display mode
-   default, saved-hosts list, .deb + RPM-subpackage CI (deb.yml/rpm.yml). **VAAPI decode
-   → DRM-PRIME dmabuf → `GdkDmabufTexture`** (BT.709 color state; Tier-1 zero-copy on
-   Intel/AMD, `PUNKTFUNK_DECODER=software|vaapi` override) with a proven fallback ladder —
-   no VAAPI device (NVIDIA) or mid-session VAAPI error → software decode. **First AMD test
-   (Steam Deck) hit a green-screen bug, fixed:** FFmpeg's VAAPI export uses
-   `SEPARATE_LAYERS`, so NV12 arrives as two single-plane layers (R8 luma + GR88 chroma,
-   one shared fd); the mapper took `layers[0]` only → GTK got a luma-only R8 texture, chroma
-   read as 0 → green field / red whites. Fix derives the combined fourcc from the decoder
-   `sw_format` (→ `DRM_FORMAT_NV12`) and flattens all planes across all layers (mpv's
-   pattern); a first-frame descriptor dump logs the real layout. Awaiting Steam Deck
-   reconfirm. Next: the stage-2 raw-Wayland
-   presenter (wp_presentation feedback, tearing-control, Vulkan Video on NVIDIA) —
-   **wgpu/winit rejected** (no dmabuf import / presentation feedback / shortcuts-inhibit).
-   **Windows stage 1 done 2026-06-15** (`clients/windows`, binary
-   `punktfunk-client`): pure-Rust **WinUI 3** UI via **windows-reactor** (a declarative React-like
-   framework backed by WinUI; PR #4499 added the `SwapChainPanel` widget + `set_swap_chain`). The
-   video is a **`SwapChainPanel`** bound to a **D3D11 composition swapchain** (WARP fallback for
-   the GPU-less dev box; runtime-compiled fullscreen-triangle shaders, Contain-fit letterbox),
-   driven by reactor's per-frame `on_rendering`. **FFmpeg HEVC decode with a D3D11VA
-   zero-copy hardware path** (`gpu.rs` shares one D3D11 device — hardware+`VIDEO_SUPPORT`, WARP
-   fallback, multithread-protected — between the decoder and presenter; the decoder outputs
-   NV12/P010 `ID3D11Texture2D` array slices with `BIND_SHADER_RESOURCE` and the presenter samples
-   them via per-plane SRVs + YUV→RGB shaders — NV12/BT.709, P010/BT.2020-PQ; **software CPU decode
-   stays as the robust fallback**, auto-selected with a `DecoderPref` override). **HDR10**: the
-   client advertises 10-bit/HDR (Settings toggle), detects PQ in-band (`transfer == SMPTE2084`),
-   and flips the swapchain to `R10G10B10A2` + ST.2084 with HDR10 metadata. **WASAPI** render + mic
-   capture, **SDL3** gamepads (rumble/lightbar/DualSense), `mdns-sd` discovery, and the full trust
-   surface — all **in-app**: a polished WinUI shell (host cards w/ monogram + status pills,
-   `InfoBar` errors/hints, `ToggleSwitch` settings, status-chip stream HUD showing GPU/CPU decode +
-   HDR), host list (live mDNS + saved + manual), settings (resolution/refresh/decoder/bitrate/HDR/
-   mic), SPAKE2 PIN pairing screen, TOFU, pinned-fp-mismatch re-pair. **(D3D11VA + HDR present + the
-   GUI polish are written against the windows-rs/reactor APIs but not yet on-glass validated — the
-   dev VM is headless/WARP; needs the RTX box.)** **Stream input** is Win32 low-level hooks (`WH_KEYBOARD_LL`/`WH_MOUSE_LL`) — reactor
-   exposes no raw key/pointer events; native Windows VK + absolute mouse (client-rect Contain-fit) +
-   wheel, Ctrl+Alt+Shift+Q capture toggle. `--headless`/`--discover` keep CLI paths. Builds + clippy
-   + fmt green on **`x86_64-pc-windows-msvc` and `aarch64-pc-windows-msvc`** — the latter
-   **cross-compiled off the one x64 runner** (no ARM64 runner; the x64 MSVC toolset's ARM64 cross
-   compiler + a per-arch `FFMPEG_DIR` ARM64 tree, SDL3/libopus build-from-source cross-compile
-   cleanly), and both ship as signed MSIX (`windows-msix.yml` matrix → `..._x64.msix`/`..._arm64.msix`,
-   verified: ARM64 binaries + manifest arch). **windows-reactor is unpublished** (git
-   dep pinned to commit `b4129fcc`; `windows` pinned to the SAME commit so `IDXGISwapChain1` unifies
-   with `set_swap_chain`); its `build.rs` downloads the Win App SDK NuGets + needs `CARGO_WORKSPACE_DIR`
-   set (in the VM build env; `/temp`+`/winmd` gitignored). Gotcha: `CARGO_HOME` must be an ASCII path
-   — the `ü` in the dev box's username breaks SDL3's MSVC precompiled-header build. Next: **on-glass
-   validation** of the D3D11VA decode + HDR present + GUI on the RTX box (the dev VM is
-   headless/Session-0/WARP → the WinUI window + hardware decode need a real display+GPU: RDP or the
-   RTX box), then RAWINPUT relative-mouse pointer-lock and a per-host speed test in the UI.
-   **Android stage 1 done** (`clients/android`, Kotlin app + `native/` Rust JNI core linking
-   `punktfunk-core`; phone + Android TV): NDK `AMediaCodec` hardware HEVC decode → `SurfaceView` incl.
-   **HDR10** (Main10/BT.2020 PQ) with low-latency tuning + a live stats HUD (`decode.rs`/`stats.rs`),
-   Opus/Oboe audio + mic uplink (`audio.rs`/`mic.rs`), gamepad input with rumble/HID feedback
-   (`feedback.rs`), **native `mdns-sd` mDNS discovery** (`discovery.rs`, polled over JNI — the same
-   browse the Linux/Windows clients use, replacing the flaky per-OEM `NsdManager`; Kotlin keeps only
-   the `MulticastLock` + permission UX), SPAKE2 PIN pairing + TOFU (Keystore identity +
-   known-host store), Compose UI (Connect/Settings/Stream) with D-pad/controller focus nav. Built for
-   `arm64-v8a` + `x86_64`; published to Google Play (Internal Testing) via `android.yml`
-   (`ci/play-upload.py`). Next: real-device gamepad/HDR live-verify, presenter/latency polish.
-2. **Sub-frame pipelining**: overlap encode and transmit within a frame. Requires a direct
-   NVENC SDK wrapper (libavcodec only emits whole AUs) — the next big latency lever (~2–4 ms
-   at high res).
-3. **punktfunk/1 protocol growth.** **Done:** unified host (`serve --gamestream` runs GameStream + the
-   punktfunk/1 QUIC host in one process; bare `serve` is the secure native-only default — GameStream is
-   opt-in, trusted-LAN only, security-review #5/#9) with native pairing driven over the mgmt API /
-   web console (`mod native_pairing`: arm-on-demand → display PIN, paired-device list).
-   **Done:** PIN pairing is the default, host-gated — the host requires pairing and advertises
-   `pair=required` unless opted out with `--allow-tofu`/`--open` (then `pair=optional`, accepts
-   unpaired clients); clients render TOFU only for a `pair=optional` host and force re-pairing on a
-   fingerprint change. **Done:** concurrent sessions — the accept loop spawns each session
-   (`--max-concurrent`, default 4, an NVENC bound), each with its own virtual output + encoder, sharing
-   the host-lifetime input/audio/mic services (shared-desktop multi-view on kwin/mutter/wlroots).
-   **Done:** delegated pairing approval (§8b-1) — an unpaired device shows up as a pending request in
-   the web console, one click approves + pins it. Next (see roadmap): gamescope multi-user isolation
-   (per-session input/audio = independent desktops); §8b-2 peer-push approval from a paired device's
-   own app.
-4. **GameStream host polish**: HDR/10-bit (needs HDR capture + metadata plumbing; `av1_nvenc
-   -highbitdepth 1` already encodes Main10 from 8-bit input on this box),
-   reconnect-at-new-mode robustness. AV1 negotiation and surround audio are implemented
-   and unit/live-capture tested — both still need a live Moonlight confirmation (select
-   AV1 in a stock client; a real 5.1/7.1 listen incl. FEC under loss).
-
-Box one-time setup is complete: udev rule + `input` group (gamepads validated live),
-gamescope 3.16.22 installed system-wide (no PATH override), gnome-shell installed (Mutter
-backend validated live). All three compositor backends are live-validated.
-
-## Build / test / run
-
-```sh
-cargo build --workspace          # green on Linux and macOS
-cargo test  --workspace          # unit + loopback + proptest + C ABI harness (~100 tests)
-cargo clippy --workspace --all-targets -- -D warnings
-cargo fmt --all --check
-
-cargo run -p loss-harness        # FEC loss-resilience sweep (no network needed)
-bash crates/punktfunk-core/tests/c/run.sh   # standalone C-ABI link + round-trip proof
-```
-
-Generated artifacts are **checked in** and CI fails on drift: `include/punktfunk_core.h`
-(cbindgen from `punktfunk-core/src/abi.rs`) and `api/openapi.json` (regenerate with
-`cargo run -p punktfunk-host -- openapi > api/openapi.json`; spec lives in `mgmt.rs`).
-
-CI is Gitea Actions (`.gitea/workflows/`, guide: docs-site `ci.md`): `ci.yml` runs the
-workspace checks inside the `git.unom.io/unom/punktfunk-rust-ci` image plus web/docs-site
-build+typecheck; `docker.yml` builds+pushes the web/docs/rust-ci images (host and native
-clients are deliberately NOT containerized); `apple.yml` builds the xcframework and runs
-`swift build`/`swift test` on the `macos-arm64` host-mode runner (home-mac-mini-1,
-provisioned by `scripts/ci/setup-macos-runner.sh`). Per-client/host release workflows:
-`deb.yml`/`rpm.yml`/`flatpak.yml` (Linux client), `android.yml` (Google Play), `windows-msix.yml`
-(Windows client), `windows-host.yml` (Windows host installer), `release.yml` (Apple notarized DMG +
-TestFlight), `decky.yml` (Steam Deck plugin); Windows builds run on a self-hosted Windows runner.

-## Design invariants — do not regress
-
-- **One core, linked everywhere.** Protocol/FEC/crypto live only in `punktfunk-core`, behind a
-  stable, versioned C ABI. `tokio`/`quinn` exist only behind the `quic` feature (control
-  plane); **no async on the per-frame path** — native threads only.
-- **Native client resolution, no scaling.** A session gets a virtual output at exactly the
-  client's WxH@Hz via the `VirtualDisplay` trait (`create(mode) → VirtualOutput { node_id,
-  remote_fd, preferred_mode, keepalive }`, RAII teardown). There is no cross-compositor
-  protocol for this — each compositor keeps its own backend.
-- **FEC is the wall-breaker.** GF(2⁸) (≤255 shards/block, Moonlight-compatible) and GF(2¹⁶)
-  Leopard (≤65535 shards/block) — punktfunk/1 negotiates the latter, removing the ~1 Gbps
-  ceiling.
-- **Core security hardening stays intact**: reassembler bounds attacker-controlled fields
-  before allocating (`ReassemblerLimits`); AES-GCM per-direction nonce salts + seq-as-AAD;
-  ABI `struct_size` checks. Regression tests exist — keep them green.
-- **PipeWire consumer discipline**: our capture streams set `node.dont-reconnect` and tear
-  down promptly on negotiation timeout — one wedged link head-blocks the daemon's shared
-  work queue system-wide.

-Pinned crate facts: `ashpd` 0.13 + `pipewire` 0.9 (must match ashpd's) + `ffmpeg-next` 8.x
-(`ffmpeg-sys-next` auto-detects the system FFmpeg, so it builds against **FFmpeg 7.x/libavcodec 61
-or 8.x/libavcodec 62** — validated live on Ubuntu 26.04 (8) and Bazzite F43 (7.1); the zero-copy
-FFI also link-needs `libGL`/`libgbm`/`libcuda` at build time). Env knobs: `PUNKTFUNK_VIDEO_SOURCE=virtual|portal`,
-`PUNKTFUNK_COMPOSITOR=kwin|gamescope|mutter`, `PUNKTFUNK_ZEROCOPY=1`, `PUNKTFUNK_GAMESCOPE_APP=...`,
-`PUNKTFUNK_INPUT_BACKEND=...`, `PUNKTFUNK_PERF=1` (per-stage timing), `PUNKTFUNK_VIDEO_DROP=N` (FEC
-test), `PUNKTFUNK_FEC_PCT=N`, `PUNKTFUNK_DSCP=1` (opt-in DSCP/SO_PRIORITY media QoS on the data +
-GameStream video/audio sockets; no-op on the wire on Windows without a qWAVE policy),
-`PUNKTFUNK_444=1` (full-chroma HEVC 4:4:4, see below).
-
-**HEVC 4:4:4 (full chroma, Range Extensions)**: opt-in via `PUNKTFUNK_444`, negotiated like 10-bit —
-the host emits 4:4:4 only when the client advertised `VIDEO_CAP_444` (wire bit `0x04` + ABI
-`PUNKTFUNK_VIDEO_CAP_444`), the codec is HEVC, the session is single-process, **and** a GPU probe
-(`encode::can_encode_444`, run before the Welcome) confirms support — else it resolves to 4:2:0 and
-`Welcome::chroma_format` reflects the real value (honest downgrade; the client reads it via
-`punktfunk_connection_chroma_format`). **punktfunk/1-native only** — GameStream/Moonlight stays 4:2:0
-(stock clients can't decode 4:4:4). **NVENC is the implemented path**: Linux `hevc_nvenc` feeds a
-swscale'd `yuv444p` (RGB-in is always 4:2:0 — verified on the RTX 5070 Ti — so the session forces CPU
-RGB capture for 4:4:4); Windows NVENC keeps ARGB input + FREXT profile + `chromaFormatIDC=3` and the
-DDA capturer delivers RGB. VAAPI / AMF / QSV **decline** (probe returns false — no validated 4:4:4
-hardware in the lab; they'd produce 4:2:0). Software (openh264) is 4:2:0-only. Test with
-`PUNKTFUNK_CLIENT_444=1 punktfunk-probe --out x.h265` then `ffprobe x.h265` (expect `pix_fmt yuv444p`).
-*Linux NVENC mechanism validated on the RTX 5070 Ti (ffmpeg CLI); Windows NVENC + 10-bit-4:4:4 not yet
-on-glass validated.*

-## Conventions
-
-- Rust 2021, `rustfmt` + `clippy -D warnings` clean before commit.
-- Match the surrounding code's comment density and naming.
-- Commit messages end with the Co-Authored-By trailer (see `git log`).
-- `pkill` caution on this box: match exact comm names (`pkill -x gamescope-wl`,
-  `pkill -x punktfunk-host`) — `pkill -f` self-matches the invoking shell.

+# Security Policy
+
+punktfunk is a low-latency desktop/game streaming stack. A host is effectively remote control of a
+machine, so we take security reports seriously and appreciate responsible disclosure.
+
+## Reporting a vulnerability
+
+**Please report security issues privately by email to security@punktfunk.com.**
+
+Do **not** open a public issue, pull request, or chat/forum post for a suspected vulnerability — that
+exposes other users before a fix exists.
+
+### What to include
+
+The more of this you can give us, the faster we can act:
+
+- The component and version (e.g. `punktfunk-host 0.6.0`, Windows or Linux, which client).
+- The impact — what an attacker can do, and from what position (same LAN, a local service account,
+  admin, a paired client, …).
+- Steps to reproduce, a proof-of-concept, or a crash/log if you have one.
+- Any suggested fix or mitigation (optional).
+
+## What to expect
+
+We're a small team, so timelines are best-effort, but we commit to:
+
+- **Acknowledge** your report within **3 business days**.
+- Give an **initial assessment** (severity + whether we can reproduce) within about **7 days**.
+- Keep you updated, and tell you when a fix ships.
+- **Credit** you in the advisory / release notes when the fix is public — unless you'd rather stay
+  anonymous.
+
+We practice **coordinated disclosure**: please give us reasonable time to release a fix before
+publishing details. We aim to resolve valid issues within **90 days** and will agree a disclosure
+date with you.
+
+## Scope
+
+In scope — the code in this repository:
+
+- The host (`punktfunk-host`), its Windows drivers, and the protocol/crypto core (`punktfunk-core`).
+- The native clients (Apple, Linux, Windows, Android), the web management console, and the management
+  API.
+
+Known limits — documented behavior, not vulnerabilities (see
+https://docs.punktfunk.unom.io/docs/security):
+
+- **Admin/SYSTEM already on the host = out of scope.** An attacker who is already administrator or
+  SYSTEM on the host owns the machine regardless of punktfunk.
+- **The virtual display is a real monitor** — any process already in the interactive desktop session
+  can capture it via the normal OS screen-capture APIs, exactly as it could a physical monitor.
+- **GameStream/Moonlight compatibility** (`--gamestream`) uses legacy encryption and is documented as
+  opt-in, trusted-LAN-only.
+- **Public-internet exposure is unsupported** — issues that only arise from exposing the host to the
+  WAN are expected; keep the host on a trusted LAN or a VPN.
+
+If you're unsure whether something is in scope, report it anyway — we'd rather hear about it.
+
+## Safe harbor
+
+We consider good-faith security research that follows this policy to be authorized, and we won't
+pursue legal action against researchers who:
+
+- make a good-faith effort to avoid privacy violations, data loss, and service disruption,
+- only test systems they own or have explicit permission to test,
+- give us reasonable time to remediate before public disclosure,
+- don't exfiltrate more data than needed to demonstrate the issue.
+
+Thank you for helping keep punktfunk and its users safe.

+## How it's built — Rust-heavy
+
+Kotlin can't `import` the cbindgen C header the way Swift can, so a native bridge is unavoidable. We
+write it in **Rust** and link `punktfunk-core` directly — so the Android client reuses the Linux
 client's orchestration (audio jitter ring, VK keymap inverse, latency/skew math, capture state
 machine, trust logic) instead of re-porting it into Kotlin.

-A working native client (phone + Android TV), at parity with the Linux and Apple apps for the core
-streaming experience:
-
-- **Video** — `AMediaCodec` hardware HEVC decode → `SurfaceView`, including **HDR10** (Main10 /
-  BT.2020 PQ), with low-latency decode tuning and a live stats HUD.
-- **Audio** — Opus + Oboe playback with a jitter ring, plus mic uplink to the host.
-- **Input** — game controllers (buttons + axes) with rumble and HID feedback; D-pad /
-  game-controller focus navigation for the couch (TV + phone).
-- **Discovery & trust** — native `mdns-sd` mDNS host list (polled over JNI; the same browse the
-  Linux/Windows clients use, not `NsdManager`), SPAKE2 PIN pairing and TOFU, with a
-  Keystore-wrapped client identity and a known-host store.
-- **UI** — Compose host list / settings / stream screens, Material You theming.
-- **Shipping** — built for `arm64-v8a` + `x86_64`; published to Google Play (Internal Testing).
-
-`crates/punktfunk-core` uses the `ring` `rcgen` backend so the client `.so` is aws-lc-free.

+- **[Project README](../../README.md)** — the host, the other clients, and how it all fits together

+//!
+//! ADPF lets a latency-critical app tell the platform "these threads run a repeating workload with
+//! this per-cycle deadline, and here's how long they *actually* took." The kernel's CPU governor
+//! (on Qualcomm Snapdragon in particular — its ADPF backend is among the most responsive) then keeps
+//! those threads on the fast cores at high clocks instead of migrating them to a little core or
+//! down-clocking between frames. For a stream client the win is on the in-process hot path we
+//! control — the `pf-decode` feed/drain/present loop — *not* the hardware codec itself (that decodes
+//! in the mediacodec service, a separate process we can't hint); keeping our loop from being
+//! scheduled late directly trims the jitter between "AU received" and "buffer released to the
+//! Surface." It complements the codec-side `operating-rate`/`priority` hints, which push the codec's
+//! own clocks.
+//!
+//! The `APerformanceHint_*` API arrived in NDK **API level 33**. minSdk is 31, so we CANNOT link the
+//! symbols directly: a `libpunktfunk_android.so` carrying an unresolved
+//! `APerformanceHint_createSession` import fails to load on API 31/32 devices
+//! (`System.loadLibrary` throws) even if the code path is never taken. Instead we resolve the

-# punktfunk Apple client (SwiftUI)
+# punktfunk — Apple client (macOS · iOS · iPadOS · tvOS)
 
-The native macOS/iOS client for **`punktfunk/1`** (the post-GameStream protocol). All
-networking/protocol work — QUIC control plane, UDP data plane, GF(2¹⁶) FEC, AES-GCM,
-input datagrams, Opus audio, cert pinning — lives in the shared Rust core (statically
-linked as `PunktfunkCore.xcframework`); this package is the Swift shell: decode
-(VideoToolbox), present (SwiftUI), input capture.
+The native **Apple** app for streaming a punktfunk host to your Mac, iPhone, iPad, or Apple TV. A
+SwiftUI app that finds hosts on your network, pairs with a PIN, and streams at your display's own
+resolution and refresh rate — with VideoToolbox hardware decode and full controller support.
 
-## Status — working client (macOS, with iOS / tvOS in the shared build)
+All the networking and protocol work — QUIC control plane, UDP data plane, GF(2¹⁶) FEC, AES-GCM,
+Opus audio, cert pinning — lives in the shared Rust **`punktfunk-core`** (statically linked as
+`PunktfunkCore.xcframework`). This package is the Swift shell: decode, present, input, and UI.
 
-A full streaming client: VideoToolbox HEVC decode, controllers incl. DualSense feedback, host
-discovery, PIN pairing, and a network speed test. The lower-latency **stage-2 presenter**
-(`VTDecompressionSession` → `CAMetalLayer`) is built and opt-in (Settings → Presenter); see below.
+## Features
 
-First light was achieved 2026-06-10 — validated live, Mac ↔ a Linux host over the LAN: gamescope
-virtual output → NVENC HEVC →
-`punktfunk/1` (GF(2¹⁶) FEC + AES-GCM over UDP, QUIC control) → VideoToolbox →
-`AVSampleBufferDisplayLayer` on glass at 1280×720@60, with mouse/keyboard flowing back as
-QUIC datagrams into the host's gamescope EIS injector (thousands of events injected during
-the session). Headless variant of the same proof: `RemoteFirstLightTests` decoded 60/60
-received AUs spanning 983 ms of host capture clock.
+- **Hardware decode** — VideoToolbox HEVC, with a low-latency **stage-2 presenter**
+  (`VTDecompressionSession` → `CAMetalLayer`, presented off a `CADisplayLink`, ~11 ms p50) as the
+  default and an `AVSampleBufferDisplayLayer` fallback.
+- **HDR & 4:4:4** — PQ passthrough with a correct reference-white anchor, mid-session SDR↔HDR
+  reconfiguration, and hardware-probed 4:4:4 support.
+- **Your display's native mode** — the host builds a virtual output at exactly your WxH@Hz;
+  mid-stream resize renegotiates without reconnecting.
+- **Audio both ways** — Opus playback (CoreAudio, no bundled libopus) with a jitter ring, plus mic
+  uplink; speaker/mic selectable in Settings.
+- **Full controller support** — one selected controller forwarded as pad 0, including **DualSense**
+  feedback (rumble → CoreHaptics, lightbar, player LEDs, adaptive triggers) and touchpad/motion. The
+  virtual pad type auto-resolves from your physical controller.
+- **Mouse & keyboard** — `GCMouse`/`GCKeyboard` capture with click-to-capture and a ⌘⎋ release, plus
+  iPad pointer lock and touch input.
+- **Find hosts automatically** — mDNS discovery (`NWBrowser` over `_punktfunk._udp`); first connect
+  does a one-time **SPAKE2 PIN pairing** (or TOFU on trusted LANs), then reconnects on a pinned,
+  Keychain-stored identity.
+- **Tune the stream** — a fps / Mb·s / **latency** HUD (skew-corrected across machines), a bitrate
+  control, a per-host **network speed test** with a recommended bitrate, and a host-compositor picker.
 
-The connector underneath (`punktfunk_core::client::NativeClient` over the C ABI) carries the
-full session: video AUs, **Opus audio** (`nextAudio()`), **rumble** (`nextRumble()`),
-**DualSense feedback** (`nextHidOutput()` — lightbar, player LEDs, adaptive-trigger
-effects), input incl. gamepads + DualSense touchpad/motion (`sendTouchpad`/`sendMotion`),
-and **cert pinning + TOFU** (`pinSHA256:`/`hostFingerprint`) — see
-`punktfunk1.rs::tests::c_abi_connection_roundtrip` (three sequential sessions: TOFU, pinned
-reconnect, wrong-pin rejection). The host (`punktfunk-host punktfunk1-host`) is a persistent listener:
-reconnect at will during development.
+Runs from one shared codebase across **macOS, iOS, iPadOS, and tvOS**.
 
-What's here, all compiled and tested on macOS (Xcode 26.5 / Swift 6.3):
+## Get it
 
-- **`PunktfunkKit`** (library)
-  - `PunktfunkConnection.swift` — wrapper over the C ABI. AUs/audio are copied into `Data`
-    (the C pointer is only valid until the next call of the same kind). `close()` is safe
-    from any thread: per-plane locks enforce the C contract ("never close with a
-    `next_au`/`next_audio` in flight") instead of leaving it to callers. Pinning + TOFU
-    via `pinSHA256:`/`hostFingerprint`.
-  - `AnnexB.swift` — in-band VPS/SPS/PPS → `CMVideoFormatDescription`; Annex-B → AVCC
-    `CMSampleBuffer` with `DisplayImmediately` set.
-  - `StreamView.swift` — SwiftUI `NSViewRepresentable` over `AVSampleBufferDisplayLayer`
-    (stage-1 presenter: the layer hardware-decodes compressed HEVC itself). One pump
-    thread per view, token-cancelled so reconnects can't double-pump.
-  - `InputCapture.swift` — `GCMouse` raw deltas + `GCKeyboard` HID→VK mapping (the host's
-    `vk_to_evdev` consumes Windows VKs), with fractional-delta accumulation so sub-pixel
-    motion isn't truncated away. Buttons use GameStream ids (1=left … 5=X2). Scroll is
-    WHEEL_DELTA(120)-scaled: macOS via the stream view's `scrollWheel` override, iPad via
-    GCMouse's scroll dpad when pointer-locked and a scroll-only `UIPanGestureRecognizer`
-    otherwise (trackpad gestures never reach GC's scroll dpad).
-  - `GamepadManager.swift` — app-lifetime controller discovery + selection (`.shared`):
-    watches `GCController` connect/disconnect, fingerprints each pad for the Settings UI
-    (name, capabilities, battery), and selects the ONE controller forwarded to the host
-    (user pin via "Use controller", else most recently connected extended gamepad).
-  - `GamepadCapture.swift` — the active controller → wire: snapshot-diff over
-    `GCExtendedGamepad` into incremental `gamepadButton`/`gamepadAxis` events (pad 0),
-    plus DualSense touchpad contacts and ~250 Hz motion samples on the rich-input plane
-    (the GC→DualSense unit conversions live in `GamepadWire`, one place). Held state is
-    released on the wire on controller switch / app deactivation / stop.
-  - `GamepadFeedback.swift` + `DualSenseTriggerEffect.swift` — host feedback → the real
-    controller: one drain thread for `nextRumble()` (→ `CHHapticEngine` per handle
-    locality) and `nextHidOutput()` (lightbar → `GCDeviceLight`, player LEDs →
-    `playerIndex`, adaptive-trigger effect blocks → a total, table-driven parser →
-    `GCDualSenseAdaptiveTrigger`, exact for the 10-zone positional modes).
-  - `HostDiscovery.swift` — LAN auto-discovery: an `NWBrowser` over `_punktfunk._udp`
-    (the host's `crate::discovery` mDNS advert), resolving each service to an IP:port via a
-    throwaway `NWConnection` and parsing the TXT (`fp` advisory cert fingerprint, `pair`,
-    stable `id`). iOS/tvOS need `NSBonjourServices` (`Config/Info.plist`) or the system
-    blocks the browse.
-- **`PunktfunkClient`** (the app): hosts grid (saved in UserDefaults) with an **On this
-  network** section listing mDNS-discovered hosts (tap to save + connect, or pair if the
-  host requires it), "+" toolbar sheet to add hosts manually, stream mode in Settings (⌘,),
-  two trust flows — the
-  trust-on-first-use fingerprint prompt over the live-but-blurred stream, and SPAKE2 PIN
-  pairing (`PairSheet`, from a host card's context menu or the trust prompt;
-  `ClientIdentityStore` keeps the client identity in the Keychain and presents it on
-  every connect) — then pinned reconnects, fps/Mb-s HUD + a **capture→client-receipt latency**
-  line (`LatencyMeter`, p50/p95): the AU `pts_ns` (host capture clock) to the instant the client
-  received it, **skew-corrected** across machines via `PunktfunkConnection.clockOffsetNs` (the
-  connect-time wall-clock handshake, `punktfunk_connection_clock_offset_ns`). It excludes the
-  layer's decode+present (stage-1 `AVSampleBufferDisplayLayer` has no per-frame present callback);
-  the opt-in **stage-2 presenter** (Settings → Presenter) adds a **capture→present**
-  (glass-to-glass) line via explicit decode + a Metal/display-link present. Settings also picks the HOST
-  compositor (KWin/wlroots/Mutter/gamescope, default automatic — the host honors it
-  only if that backend is available there) and has a **Controllers** section: every
-  detected controller (capability glyphs, battery, "In use" badge), which one to forward
-  ("Use controller", default automatic), and the virtual pad type the host creates
-  ("Controller type": Automatic / Xbox 360 / DualSense — Automatic matches the physical
-  pad; resolved at connect time, the host pad is fixed per session). Gamepad capture +
-  feedback run with streaming (`SessionModel` owns them, same trust gate as audio).
-  Settings also sets the **Bitrate** (Automatic toggle = host default; manual is a
-  log-scale slider, 2 Mbps – 3 Gbps, snapped to two significant figures — above 1 Gbps
-  an inline warning says to run a speed test first; tvOS uses a preset picker instead,
-  Slider doesn't exist there; negotiated via the Hello on every connect), and a host
-  card's context menu offers **"Test Network Speed…"** (`SpeedTestSheet`): connects, has
-  the host burst probe filler over the real data plane (up to the host's 3 Gbps probe
-  ceiling for 2 s, roadmap §9),
-  shows measured goodput · loss · a recommended bitrate (≈70% of measured), and applies
-  it in one tap. The streaming **statistics overlay** can be turned off and moved to any
-  corner (Settings → Display → Statistics, `DefaultsKey.hudEnabled`/`hudPlacement`), and
-  toggled live with **⌘⇧S** — a Scene-level **"Stream" menu** (`StreamCommands`) that also
-  carries **Disconnect ⌘D**, so disconnect survives the HUD being hidden (on iOS a small
-  exit chip appears instead; on tvOS the Siri-Remote Menu button still disconnects). The
-  macOS Settings window is a **tabbed preferences pane** (General / Display / Audio /
-  Controllers / Advanced) — the sections are shared with the iOS single-Form layout and the
-  tvOS pushed-picker layout, defined once each.
-- **Tests** (`swift test`): byte-level Annex-B units; a real-codec round trip
-  (VTCompressionSession-encoded HEVC rebuilt as the host's wire shape → `AnnexB` →
-  VTDecompressionSession → pixels); table-driven DualSense trigger-effect parsing
-  (`DualSenseTriggerEffectTests`) and the gamepad wire conversions
-  (`GamepadWireTests`); loopback integration against real local hosts
-  (`test-loopback.sh` — stream round trip incl. gamepad/touchpad/motion sends, a
-  host-scripted feedback burst asserted on the rumble + HID-output planes
-  (`PUNKTFUNK_TEST_FEEDBACK=1`), the bitrate-negotiation echo and a real 20 Mbps
-  bandwidth probe, plus the PIN pairing ceremony and the `--require-pairing` gate
-  against a second, armed host); the remote first-light test above.

-## Xcode project (`Punktfunk.xcodeproj`)
+## Project layout
 
-The app target **Punktfunk** wraps the same sources as the `swift run` shell
-(`Sources/PunktfunkClient`, a synchronized folder — no duplication) plus `App/` (asset
-catalog) and links `PunktfunkKit` from the local package. Generated Info.plist, ad-hoc
-signing, bundle id `io.unom.punktfunk`. Notes:
+- **`PunktfunkKit`** (library) — the reusable pieces:
+  - `PunktfunkConnection` — the wrapper over the C ABI (thread-safe `close()`, per-plane locks,
+    pinning + TOFU).
+  - `AnnexB` / `StreamView` / `VideoDecoder` / `MetalVideoPresenter` — format handling, the stage-1
+    (`AVSampleBufferDisplayLayer`) and stage-2 (`VTDecompressionSession` → `CAMetalLayer`) presenters.
+  - `InputCapture` — `GCMouse`/`GCKeyboard` → host VK/mouse, with fractional-delta accumulation.
+  - `GamepadManager` / `GamepadCapture` / `GamepadFeedback` / `DualSenseTriggerEffect` — controller
+    discovery + selection, capture (buttons/axes/touchpad/motion), and host-feedback rendering.
+  - `HostDiscovery` — `NWBrowser` over `_punktfunk._udp`.
+- **`PunktfunkClient`** (the app) — hosts grid with an *On this network* section, add-host sheet,
+  the two trust flows (TOFU prompt + SPAKE2 `PairSheet`), the stream view with the HUD, a
+  tabbed Settings pane (General / Display / Audio / Controllers / Advanced), and the network speed
+  test. A Scene-level **Stream** menu carries Disconnect (⌘D) and the HUD toggle (⌘⇧S).
+  On iOS/iPadOS **and macOS** a connected controller swaps the whole home for the **gamepad UI**
+  (`Home/Gamepad*`, `Settings/GamepadSettingsView`): a console-style host carousel (A connect · Y
+  library · X settings), a controller-navigable settings screen, an add-host flow with an
+  on-screen controller keyboard (no touch required anywhere), and the coverflow library browser —
+  all driven by the shared `GamepadMenuInput` poller + `GamepadCarousel`/`GamepadMenuList` focus
+  machinery, with dual-channel haptics (device Taptic + controller `MenuHaptics`), over an
+  animated "aurora" backdrop (`GamepadScreenBackground` — TimelineView-driven drifting color
+  blobs; deliberately pure SwiftUI, since a .metal library only reliably bundles in one of the
+  two build systems these sources compile under). macOS presents the settings/add-host screens as
+  sheets (no `fullScreenCover` there); `PUNKTFUNK_FORCE_GAMEPAD_UI=1` forces the mode without a
+  physical pad (dev/screenshots).
+- **Tests** (`swift test`) — Annex-B units, a real-codec VideoToolbox round trip, DualSense
+  trigger-effect and gamepad-wire conversions, loopback integration against real local hosts, and the
+  remote first-light test.
 
-- **Entitlements (sandbox)**: the macOS target uses
-  `Config/Punktfunk-macOS.entitlements`; iOS/tvOS use the shared
-  `Config/Punktfunk.entitlements`. The macOS app is **App-Sandboxed** (mandatory for the Mac
-  App Store/TestFlight, and used for the Developer ID DMG too so the local build matches what
-  ships): `com.apple.security.app-sandbox`, `network.client` + **`network.server`** (the
-  sandbox gates `bind()`; quinn + the raw-UDP plane both bind, so receive breaks without it),
-  `device.audio-input` (mic), `device.bluetooth` + `device.usb` (GameController over BT/USB),
-  and the existing `keychain-access-groups`. `app-sandbox` is macOS-only — keep it OUT of the
-  shared iOS/tvOS file (it fails upload validation there). Verify a build is sandboxed with
-  `codesign -d --entitlements :- <built .app>`. Heads-up: `device.usb` draws some App Review
-  scrutiny — justify it in the review notes ("reads input from USB game controllers").
-- **App icon**: `App/Assets.xcassets` ships an empty `AppIcon` slot. For an Icon Composer
-  `.icon`: add the file to the project (target Punktfunk), set it as the App Icon in the
-  target's General tab, and delete the placeholder `AppIcon.appiconset`. Heads-up: CLI
-  `actool` (Xcode 26.5) crashed compiling `punktfunk_Logo.icon` — if Xcode does the same,
-  suspect the icon bundle (it has a duplicate-named layer, "…Layer-3 2.svg"), not the
-  project.
-- **Tests from Xcode**: the package tests run with `swift test`; to get them on ⌘U, add
-  `PunktfunkKitTests` once via Edit Scheme → Test → + (Xcode persists it into the shared
-  scheme — a hand-written package-test reference doesn't resolve headlessly).
-- `xcodebuild -project Punktfunk.xcodeproj -scheme Punktfunk build` works headlessly;
-  same for `-scheme Punktfunk-iOS -destination 'generic/platform=iOS Simulator'` (run it
-  in a simulator via `xcrun simctl install/launch` — `SIMCTL_CHILD_PUNKTFUNK_AUTOCONNECT=…`
-  passes the dev autoconnect env through).
+## Notes for contributors
 
-## App Store screenshots
+- **Xcode project** (`Punktfunk.xcodeproj`) wraps the same sources as the `swift run` shell (a
+  synchronized folder — no duplication). The macOS target is **App-Sandboxed** (needs
+  `network.server` — the raw-UDP plane and quinn both `bind()`); iOS/tvOS use the shared
+  entitlements file (keep `app-sandbox` **out** of it). Verify with
+  `codesign -d --entitlements :- <built .app>`.
+- **Decode flow**: the host opens every stream with an IDR carrying VPS/SPS/PPS in-band, and recovery
+  keyframes re-send them — refresh the format description on every IDR; there is no out-of-band
+  extradata, ever.
+- **ABI threading**: one video pump thread per connection, one optional audio drain thread, and one
+  optional feedback drain thread (rumble + HID-output). `send()` is enqueue-only and safe alongside
+  all of them. The wrapper's per-plane locks make `close()` safe from anywhere.
+- **DualSense motion scale** (`GamepadWire`) is derived from hid-playstation's math, not yet
+  live-verified — if gyro/accel feel wrong in a game, correct sign/scale there and `evtest` the
+  host's virtual pad.
+- **App Store screenshots** are automated — `tools/screenshots.sh all` renders the real UI at the
+  required pixel sizes via a DEBUG-only shot mode; the `apple` CI workflow captures the iOS sizes on
+  every main push. See the script header for details.
+- Deeper design notes live in [`design/apple-stage2-presenter.md`](../../design/apple-stage2-presenter.md).
 
-Automated, faithful screenshots of the real UI for App Store Connect — one set per platform at
-exactly the accepted pixel sizes. Driver: **`tools/screenshots.sh`**.

-```sh
-tools/screenshots.sh all                 # macOS + (if full Xcode) iOS, iPadOS, tvOS → ./screenshots
-tools/screenshots.sh macos               # just macOS
-OUT=~/Desktop/shots tools/screenshots.sh ios ipad tvos
-PUNKTFUNK_SHOT_HERO=~/frame.png tools/screenshots.sh ios   # real captured frame behind the hero
-```
-
-How it works: the app has a DEBUG-only **shot mode** (`Sources/PunktfunkClient/Screenshots/`).
-Launched with `PUNKTFUNK_SHOT_SCENE=<name>` it renders **one** mock-populated screen full-bleed
-(`ScreenshotHostView`) instead of `ContentView`, then the OS screenshots the *real, fully-rendered*
-window — `screencapture` on macOS, `xcrun simctl io booted screenshot` on the Simulators. The five
-scenes (`ShotScenes.all`): `01-stream` (the stream hero — a synthetic frame + the glass HUD, since
-`StreamView` needs a live connection), `02-hosts`, `03-pair`, `04-trust`, `05-settings`. Mock data
-is in `ShotMock`; nothing touches a host.
-
-Output pixels are App Store Connect's required/largest sizes (Apple auto-derives the smaller ones):
-`mac` 2880×1800 · `iphone-6.9` 1320×2868 (hero 2868×1320) · `ipad-13` 2064×2752 (hero 2752×2064) ·
-`appletv` 1920×1080.
-
-Why not `ImageRenderer` (the obvious offscreen route)? It can't rasterize this app's chrome —
-`NavigationStack`, `Form`/`TabView`, and Liquid-Glass/`NSVisualEffect` materials all render black or
-SwiftUI's "can't render" placeholder. Capturing the live window/Simulator avoids that entirely.
-
-Requirements / gotchas:
-- **macOS**: only the Swift toolchain is needed, **plus a one-time Screen Recording grant** for
-  your terminal (System Settings → Privacy & Security → Screen Recording) — without it
-  `screencapture -l` fails with "could not create image from window". (A no-permission fallback,
-  `PUNKTFUNK_SHOT_SELFCAPTURE=<dir>`, uses `cacheDisplay` — but it omits material blur and can't
-  read `ScrollView` content, so it's for quick checks, not submission.)
-- **iOS/iPadOS/tvOS**: needs **full Xcode** (xcodebuild + Simulators), not just Command Line Tools,
-  and the matching device Simulators installed (iPhone 16 Pro Max, iPad Pro 13", Apple TV). Run it
-  on a full-Xcode Mac (e.g. the `macos-arm64` CI mini).
-- The hero defaults to a synthetic synthwave frame — set `PUNKTFUNK_SHOT_HERO` to a real captured
-  frame for a production-quality lead screenshot.
-
-**CI**: the `apple` workflow's **`screenshots`** job runs on the `macos-arm64` runner on every main
-push + manual dispatch (skipped on PRs), and attaches the result as a single zip artifact,
-**`punktfunk-appstore-screenshots`** (download it from the run's Artifacts; `upload-artifact@v3` —
-Gitea's backend rejects v4). It captures the two **required iOS sizes — iPhone 6.9" + iPad 13"** —
-on the Simulator (auto-creating the device if the runner lacks it), and is isolated from the
-build/test job so a capture hiccup never reds the build.
-
-**macOS and tvOS are NOT in CI**, by design: the self-hosted runner is **headless** (no
-window-server session), so the macOS window capture can't run there, and tvOS needs the Tier-3
-build-std slice. Generate those on a GUI Mac: `tools/screenshots.sh macos tvos`. (If the runner is
-ever switched to a logged-in GUI session, re-adding macOS to the job's capture step is one line.)
-
-## Notes for whoever picks this up next
-
-1. **cbindgen import quirk** (the predicted "small compile fixes", now fixed): the
-   C17-compatible header spells `PunktfunkStatus`/`PunktfunkInputKind` as integer typedefs while
-   the enum *constants* import into Swift as a distinct same-named type — bridge with
-   `.rawValue` (see the top of `PunktfunkConnection.swift`). Don't fight the generated header.
-2. **ABI contract**: one video pump thread per connection, plus optionally one *separate*
-   audio drain thread for `nextAudio()` and one feedback drain thread for
-   `nextRumble()`/`nextHidOutput()` (the core keeps per-plane borrow slots, so the planes
-   never alias; rumble + HID-output are two planes drained sequentially by the one
-   feedback thread); `send()` is enqueue-only and safe alongside all of them. The
-   wrapper's per-plane locks make `close()` safe from anywhere (it waits out in-flight
-   polls, ≤ their timeouts).
-3. **Decode flow**: the host opens every stream with an IDR carrying VPS/SPS/PPS in-band
-   and recovery keyframes re-send them — "refresh the format description on every IDR"
-   (what `StreamView` does) is sufficient; there is no out-of-band extradata, ever.
-4. **Stage 2 — built, opt-in (`punktfunk.presenter == "stage2"`, default stage 1).** Explicit
-   `VTDecompressionSession` decode (`VideoDecoder`) → a `CAMetalLayer` + display-link present
-   (`MetalVideoPresenter`/`Stage2Pipeline`), hosted as a sublayer by the same `StreamView`s with
-   input capture + HUD unchanged. It adds a **capture→present** (glass-to-glass, modulo the host
-   render→capture term) HUD line, skew-corrected via `PunktfunkConnection.clockOffsetNs`. The
-   decode half is unit-tested (`testVideoDecoderAsyncCallbackDeliversPixels`); the Metal present
-   is display-bound — **validate live** (flip the Settings "Presenter" picker, watch the HUD
-   number and that the image looks right) before making it the default. 10-bit/HDR + a smoothing
-   pacer are later. Plan: `docs-site/content/docs/apple-stage2-presenter.md`.
-5. **Audio — wired, both directions.** Playback: `SessionAudio` drains `nextAudio()`
-   on its own thread, decodes through CoreAudio's built-in Opus codec (`OpusCodec.swift`
-   — kAudioFormatOpus, no bundled libopus; round-trip unit-tested) into a priming
-   jitter ring feeding an `AVAudioSourceNode`. Mic: a second engine taps the input
-   device, resamples to 48 kHz stereo, Opus-encodes 20 ms chunks and `sendMic()`s them
-   (the host's virtual PipeWire source accepts any frame size ≤ 120 ms). Speaker/mic
-   are chosen in Settings (`AudioDevices.swift` — persisted by UID; "System default"
-   leaves the engines unpinned so they follow macOS device changes), mic on/off toggle
-   included; the app asks for mic permission on first use
-   (NSMicrophoneUsageDescription is in the Xcode target). A/V sync and packet-loss
-   concealment beyond silence-fill are still open (AudioPacket.seq/ptsNs carry what's
-   needed). Decode with libopus or `AVAudioConverter`/`kAudioFormatOpus` into an
-   `AVAudioEngine` source node; conceal gaps (drop/dup) rather than blocking — the Rust
-   side buffers 320 ms and drops the newest packet when the puller lags. Wall-clock
-   `ptsNs` shares the host clock with video AUs for A/V sync. Wiring this into
-   `PunktfunkClient` is the next app-side task.
-6. **Gamepads — wired end to end.** Exactly ONE controller (the `GamepadManager`
-   selection) forwards as pad 0; the host accumulates the incremental events into a
-   virtual pad whose TYPE the client negotiates in the Hello (`gamepad:` connect
-   parameter, echoed resolved in `resolvedGamepad` — Automatic resolves from the physical
-   pad at connect time; host precedence: explicit client choice > host `PUNKTFUNK_GAMEPAD`
-   env > Xbox 360). A DualSense session carries the full feel: adaptive-trigger blocks
-   (`DualSenseTriggerEffect.parse` — mode bytes per the community convention
-   (Nielk1/ds5w/inputtino), total, unknown → `.off`), lightbar, player LEDs, touchpad,
-   motion. **Motion scale constants** (`GamepadWire.gyroLSBPerRadS` = 20 LSB per deg/s,
-   `accelLSBPerG` = 10000) are derived from hid-playstation's math over the host's fixed
-   calibration blob, not yet live-verified — if gyro/accel feel wrong in a real game,
-   correct sign/scale in `GamepadCapture.forwardMotion`/`GamepadWire` and `evtest` the
-   host's virtual pad. Twin identical controllers share a fingerprint base, so a manual
-   pin can swap between them across reconnects (documented in the Settings footer).
-7. **Trust — the full ceremony exists now (SPAKE2).** `generateIdentity()` once (persist
-   both PEMs in the Keychain), then `pair(host:identity:pin:name:)` with the 4-digit PIN
-   the host prints when it ARMS pairing (`--allow-pairing`/`--require-pairing`; one PIN
-   per arming window, surfaced in the host's web console — port 3000 → Pairing — and
-   printed at startup; the user reads it before pairing). Returns the
-   host's VERIFIED fingerprint; persist it and pass `pinSHA256:` + `identity:` to every
-   connect. Pairing is a real PAKE: a wrong PIN gets ONE online guess (no offline
-   dictionary attack), throwing `.wrongPIN`; a wrong-size pin throws `.invalidPin`. `PunktfunkClient` implements both flows:
-   the TOFU fingerprint sheet keeps working against hosts not running
-   `--require-pairing`, and the PIN ceremony is wired in — `ClientIdentityStore`
-   (Keychain) on every connect, `PairSheet` from a host card's context menu or the trust
-   prompt's "Pair with PIN instead…" (the host's accept loop is sequential, so that path
-   drops the live session before pairing). With `--require-pairing` the host now
-   authorizes clients too (the "other direction" is no longer open, opt-in per host);
-   the whole gate is regression-tested in `testPairingCeremonyAndRequirePairingGate`.
-7b. **Resize without reconnect**: `requestMode(width:height:refreshHz:)` mid-stream —
-   the host rebuilds at the new mode in ~90 ms; the first new-mode AU is an IDR with
-   fresh parameter sets (the refresh-on-IDR decode flow handles it untouched) and
-   `currentMode()` reflects the switch. Wire it to window-resize events.
-8. **Input capture** (stage 1): capture is a deliberate, reversible STATE owned by
-   `StreamLayerView`, Moonlight-style. Engaged when the stream starts / trust is
-   confirmed and when the user clicks into the video (that click is suppressed toward
-   the host); released by ⌘⎋ (toggles) or focus loss; NEVER engaged by mere app
-   activation — activating clicks may be title-bar drags or resizes, which used to get
-   their cursor warped away mid-drag. While captured: the local cursor is hidden +
-   frozen mid-view (the host renders its own), all input is forwarded, and the view
-   consumes key events as first responder so unhandled keyDowns don't beep — ⌘-combos
-   still work locally (⌘D disconnect, ⌘Q) *and* reach the host via GC. While released:
-   nothing is forwarded (`InputCapture.forwarding` gates the GC handlers; held
-   keys/buttons are flushed host-side on release so nothing sticks down), the cursor is
-   free, and the HUD shows "Click the stream to capture input". GC handlers only fire
-   while the app has focus, and focus loss also auto-releases everything held. One live capture per process (the GC
-   mouse/keyboard singletons have a single handler slot — ownership is tracked so a stale
-   capture's stop() can't clobber a newer one).
-9. **iOS/iPadOS — ported and first-lit** (iPad simulator ↔ the real host, 60 fps).
-   `BUILD_IOS=1 bash scripts/build-xcframework.sh` builds device + universal-simulator
-   slices; the Xcode project has a second target, **Punktfunk-iOS**, sharing the same
-   synchronized sources. The iOS `StreamView` (StreamViewIOS.swift — same name/signature
-   as the macOS one, so the SwiftUI shell is identical) hosts the shared `StreamPump` in
-   a view controller for `prefersPointerLocked`: with a hardware mouse/trackpad that is
-   the iPadOS cursor capture (system honors it fullscreen-and-frontmost; in Stage
-   Manager it degrades to absolute-mouse forwarding). Input is routed by kind: DIRECT
-   fingers / Pencil are touches (each gets a wire touch id, coordinates mapped through the
-   aspect-fit letterbox into host-mode pixels — surface == host mode, so the host rescale is
-   the identity), while a mouse/trackpad is a MOUSE — pointer-LOCKED it is GCMouse relative
-   deltas; unlocked it is absolute moves + buttons + scroll over the UIKit pointer path
-   (hover + `.indirectPointer` touches), the local cursor staying visible so you can aim. An
-   indirect pointer is never sent as a touch. Touch is gated on trust (not forwarded under
-   the TOFU prompt), and returning to the foreground restores the capture you had on leaving.
-   `InputCapture` is cross-platform (GC works the same on iPadOS; ⌘⎋ is detected from
-   the HID stream there); audio routes via `AVAudioSession` (the Settings device
-   pickers are macOS-only). For the iPad-with-external-display setup: the target
-   enables multiple scenes + indirect input events — on Stage Manager iPads, drag the
-   punktfunk window onto the external screen and the stream runs there with full
-   keyboard/mouse/touch. While streaming the session is immersive (edge-to-edge,
-   status bar + home indicator hidden) and the iPadOS cursor is hidden over the video only
-   while the scene is actually pointer-LOCKED (`UIPointerInteraction` `.hidden()`); when the
-   lock isn't held it stays visible and the mouse forwards as an absolute cursor instead; on
-   iOS first run the stream mode defaults to the device's native screen so the video
-   fills the display. **tvOS** runs the same app (target **Punktfunk-tvOS**, first-lit
-   in the Apple TV simulator at 720p60): playback-only audio (no mic on tvOS),
-   focus-driven UI (`.card` host tiles), no kb/mouse capture yet — input lands with
-   gamepad support, the natural tvOS input anyway. While streaming there is NO focusable
-   control (a focusable Disconnect button would let the focus engine eat the controller's A
-   before the host sees it); the Siri Remote's **Menu** button disconnects (`.onExitCommand`).
-   Core slices are tier-3 Rust targets (see Build above). Known gaps: true pointer LOCK (`prefersPointerLocked`) isn't
-   consulted through UIHostingController, so the hidden cursor can still drift onto a
-   second screen (fixing it means putting the controller into the UIKit presentation
-   chain); and
-   AVAudioSession interruptions (calls, Siri) don't auto-restart the audio engines yet
-   (reconnect recovers).
-
-## Known limitations of the current host (relevant to client UX)
-
-- One session **at a time** (the listener is persistent, but a second concurrent client
-  waits in the accept queue until the current session ends — the virtual output and
-  encoder are single-tenant).
-- Mid-stream renegotiation (resolution change without reconnect) is designed-for but not
-  implemented (the Welcome is one-shot today).
-- Host-side gamepad injection needs `/dev/uinput` access on the box (udev rule from
-  `design/linux-setup.md`).

+// The one piece of gamepad-menu machinery shared by the host launcher (GamepadHomeView) and the
+// library coverflow (LibraryCoverflowView): a horizontal, center-snapping carousel driven entirely
+// by a controller (iOS/iPadOS/macOS).
+//
+// The scrolling is pure native SwiftUI — `.scrollTargetLayout()` + `.scrollTargetBehavior(.viewAligned)`
+// snap exactly one item to center, and symmetric `.safeAreaPadding(.horizontal)` (sized off the live
+// container width, so it's correct in an iPad split view too) lets the first and last item reach the
+// middle. The CALLER owns each card's look, including its own `.scrollTransition` — this component
+// deliberately applies none, so a screen can chain the VisualEffect-only transition modifiers without
+// the generic wrapper here pushing the type-checker onto an overload it can't satisfy.
+//
+// Navigation authority: an internal `cursor` (an index), NOT the scroll-position binding, is the
+// source of truth for where the gamepad is. `.scrollPosition(id:)` is a two-way binding and the
+// scroll view WRITES intermediate ids into it while a programmatic animation is in flight — so
+// reading the "current" item back out of it to compute the next one desyncs badly on a fast held
+// stick (each move reads a lagging value and the cursor stalls before the last item). Instead a move
+// advances `cursor` synchronously and points the scroll view at `items[cursor]`; scroll read-back is
+// only allowed to move the cursor when the gamepad hasn't driven recently (i.e. a touch drag).
+//
+// Feedback is dual-channel by design: `.sensoryFeedback` ticks the DEVICE Taptic engine (for a
+// handheld/touch user) and `MenuHaptics` ticks the CONTROLLER (for a couch user holding the pad).
+// Both fire on a move, on confirm, and — for a non-wrapping list — a duller bump plus a short visual
+// recoil when a move is refused at either end.

+// The vertical sibling of GamepadCarousel (iOS/iPadOS/macOS): a controller-driven focus list for
+// the gamepad UI's form-like screens (GamepadSettingsView, GamepadAddHostView). Up/down moves a
+// focus bar through the rows, left/right adjusts the focused row's value, A activates it, B backs
+// out. The CALLER owns each row's look (it gets the focused flag); this component owns the focus
+// cursor, controller polling, haptics, and keeping the focused row scrolled into view.
+//
+// Unlike the carousel there is no snapping and no `.scrollPosition` two-way binding to fight: the
+// cursor is plainly authoritative, the scroll view just chases it with `scrollTo`. Touch stays a
+// first-class fallback — tapping a row focuses AND activates it (rows are always fully visible, so
+// the carousel's "first tap re-centers" step would only add friction here), and free finger
+// scrolling is never hijacked back to the focused row until the next controller move.
+//
+// Feedback is dual-channel like the carousel: `.sensoryFeedback` ticks the DEVICE Taptic engine,
+// `MenuHaptics` ticks the CONTROLLER. Moves and value changes get the crisp detent; a refused
+// move at either end gets the dull boundary thud plus a short vertical recoil.
