windows.yml + windows-msix.yml gain an x86_64/aarch64 target matrix. ARM64 is
cross-compiled on the one x64 Windows runner — the x64 MSVC toolset ships the
ARM64 cross compiler, aarch64-pc-windows-msvc is tier-2 with host tools, and
SDL3/libopus (build-from-source) cross-compile cleanly. The only arch-specific
external dep is FFmpeg's import libs: the matrix points FFMPEG_DIR at a per-arch
tree (x64 C:\Users\Public\ffmpeg, arm64 C:\Users\Public\ffmpeg-arm64, both
FFmpeg 7.x / avcodec-61). Per-arch short CARGO_TARGET_DIR avoids a shared target
dir; fmt + test run only for x64 (aarch64 can't execute on the x64 host).
pack-msix.ps1 gains -Arch x64|arm64 (stamps the manifest ProcessorArchitecture,
arch-suffixes the .msix/.cer); windows-msix.yml matrixes both arches and
publishes ..._x64.msix / ..._arm64.msix. setup-windows-runner.ps1 provisions the
rustup target + the ARM64 FFmpeg tree (idempotent).
Verified live on the runner (home-windows-1): debug+release cross-build green,
clippy -D warnings green, and MSIX pack produces a valid arm64 package (manifest
arch=arm64; bundled exe/SDL3/avcodec/reactor-bootstrap all PE machine 0xAA64).

The cfg(windows) code can't be lint-checked on the Linux dev box, so three
-D warnings slipped through (caught by windows.yml; the FFI + shaders compiled
fine):
- gpu.rs: SetMultithreadProtected returns a must-use BOOL -> `let _ =`.
- video.rs: drop the unused GpuFrame::ten_bit field (present keys off `hdr`;
the value is still computed locally for the first-frame log).
- present.rs: GpuView::frame is an RAII keep-alive (its Drop returns the decoder
surface to the pool), never read -> #[allow(dead_code)].

The client was pure software HEVC decode + CPU swscale->RGBA + a full-frame
dynamic-texture upload every frame -- the reason performance was poor on a GPU
box (the GPU sat idle while the CPU churned). This adds a hardware path, HDR,
and a GUI pass.
Performance -- D3D11VA zero-copy:
- gpu.rs (new): one D3D11 device (hardware + VIDEO_SUPPORT, WARP fallback,
multithread-protected) shared by decoder and presenter via a Send/Sync
OnceLock. Sharing is mandatory -- a decoded texture is only bindable on the
device that created it. windows-rs COM interfaces are !Send/!Sync, so the
unsafe impl is sound only under the multithread protection + disjoint
decode(video ctx)/present(immediate ctx) split.
- video.rs: D3d11vaDecoder (raw FFI mirroring the Linux VAAPI module). The
COM-typed AVD3D11VA{Device,Frames}Context are declared here (stable FFmpeg
ABI) to avoid ffmpeg-sys binding the d3d11 headers; get_format builds a frames
ctx with BindFlags=SHADER_RESOURCE so the NV12/P010 array slices are
sampleable. av_frame_clone guard keeps each surface out of the reuse pool
until the presenter drops it. Software decode stays as the fallback
(DecoderPref Auto/Hardware/Software; auto falls back on init/decode error).
- present.rs: shared device; per-plane SRVs over the array slice
(NV12->R8/R8G8, P010->R16/R16G16) + three pixel shaders (RGBA passthrough,
NV12/BT.709, P010/BT.2020-PQ). present() now takes the frame by value so the
GPU surface survives re-presents.
HDR:
- Detected in-band (transfer == SMPTE2084), same signal as the other clients.
Swapchain flips to R10G10B10A2 + ST.2084 + HDR10 metadata. New Settings toggle
gates advertising VIDEO_CAP_10BIT|HDR; host still gates 10-bit behind its own
PUNKTFUNK_10BIT + actual-HDR-content checks.
GUI (windows-reactor):
- Host cards with accent-monogram avatars + colored status pills, InfoBar for
errors/pairing hints, ToggleSwitch settings (+ HDR, decoder, bitrate), button
icons, a richer connecting screen, and a stream HUD with GPU/CPU-decode + HDR
status chips.
Not yet on-glass validated: the Linux dev box can't compile the cfg(windows)
code (ffmpeg/windows crates unfetched; WARP has no hw decode) -- only
cargo fmt checks it here. API shapes verified against the windows-rs/reactor
source and the YUV->RGB coefficients checked by hand, but D3D11VA + shaders +
the GUI need a real build (Windows CI / build VM) and on-glass test on the RTX
box. The host-side HDR encode path is unchanged.

Two bodies of work in one commit (the rename moved files the fixes also touched).
Naming/structure cleanup (pre-launch):
- Host modules m3.rs->punktfunk1.rs, m0.rs->spike.rs; CLI m3-host->punktfunk1-host,
m0->spike; bare `punktfunk-host` now prints help. Types M3Options/M3Source->
Punktfunk1Options/Punktfunk1Source.
- Clients consolidated out of crates/ into clients/: punktfunk-client-rs->
clients/probe (crate punktfunk-probe), client-linux->clients/linux,
client-windows->clients/windows, punktfunk-android->clients/android/native
(crate punktfunk-client-android; kept [lib] name=punktfunk_android so the JNI
contract is unchanged). crates/ now holds only core + host.
- Milestone codes M0-M4 purged from code/CLI/CLAUDE.md/README/docs/docs-site,
kept only in docs/implementation-plan.md. docs/m2-plan.md->
docs/gamestream-host-plan.md. CI/gradle/flatpak paths updated.
Client loss-recovery (video froze and never recovered after a brief drop):
- Export punktfunk_connection_frames_dropped through the C ABI (the core already
tracked it for the client keyframe-recovery loop; it was never reachable from
the ABI clients). Regenerated punktfunk_core.h.
- Apple (StreamPump + Stage2Pipeline) and Android (decode.rs) now poll
frames_dropped and request a keyframe when it climbs -- the same loss-driven
recovery Linux/Windows already had. Under infinite GOP the decoder silently
conceals reference-missing frames, so the decode-error trigger rarely fires.
Apple rumble robustness (worked then went spotty -- DualSense + Xbox):
- Add CHHapticEngine stopped/reset handlers (rebuild on app background / audio
interruption / server reset) and drop the permanent `broken` latch on a
transient drive failure; latch only when the controller truly has no haptics.
- Surface swallowed SDL set_rumble errors on Linux/Windows + diagnostic logging.
Verified: cargo build/clippy/fmt --workspace, C-ABI harness, header drift.
Not runnable on this box (verify in CI): Gitea workflows, gradle/Android,
flatpak, Swift/decky.
