UX polish batch 1 (clients/windows/ui-polish-plan.md, workstreams W0/A1/B/C/E):
- W0: the shell's duplicated trust/settings structs are gone — src/trust.rs
re-exports pf-client-core's, so the shell and the spawned session binary share
ONE Settings shape over client-windows-settings.json. Fixes real bugs: the
shell's saves no longer drop session-side fields; the stats-overlay toggle
(show_hud -> show_stats, serde alias migrates old files) and the forwarded-
controller pick now actually reach the spawned session. The "Streaming engine"
Settings combo is gone (PUNKTFUNK_BUILTIN_STREAM=1 stays as the dev A/B knob).
- Forwarded-controller pinning by stable key (vid:pid:name, pf-client-core's
format): persisted as forward_pad, applied by the shell's own service at
startup AND by the session binary in session_params (both OSes — the session
never applied the pin before).
- A1 single window: the shell hides itself when the spawned session window
presents its first frame ({"ready":true}) and restores + foregrounds on the
child's exit — exactly one visible Punktfunk window at any time. Restore runs
before the request-access cancel gate so a Ready/Cancel race can't strand the
shell hidden.
- C console UI: punktfunk-session --browse gains --json-status (ready when the
library window presents; error line on a failed start), and the shell
surfaces it — "Open console UI" on paired hosts' menus, plus a controller-
detected hint card targeting the most recent paired host (x64 only; aarch64
ships no skia ui feature). Browse spawns hide/restore the shell like streams.
- B responsive: minimum window size (420x360); the hosts header collapses to
icon-only buttons below 700 px; the session status card shrinks instead of
clipping (max_width); busy pages, help actions, licenses and long labels wrap.
- E polish: session exe gets the app icon (winresource + WM_SETICON via the new
pf-presenter win32.rs); both exes share an explicit AppUserModelID on
unpackaged runs (packaged identity wins) so the windows group as one taskbar
app across the visibility handoff; "Start streams fullscreen" toggle passes
--fullscreen (GTK parity); connects stamp KnownHost::last_used; the connect
target is stashed for every route so "Connecting to X" always names the host.

The punktfunk-session Vulkan client (clients/linux-session, now clients/session)
builds and runs on Windows; the WinUI shell spawns it for every stream. Verified
live: 10-bit HEVC via Vulkan Video on both AMD (iGPU) and NVIDIA, 5120x1440 at
130 fps / 8 ms end-to-end on the RTX 4090.
- pf-ffvk: Windows bindgen branch (FFMPEG_DIR + PF_FFVK_VULKAN_INCLUDE, no
pkg-config); provisioning fetches Vulkan-Headers (pinned v1.4.309).
- pf-client-core: builds on Windows — WASAPI audio (audio_wasapi.rs, cfg-swapped
via #[path], same surface as the PipeWire twin), VAAPI/dmabuf gated inline
(chain = vulkan -> software), trust reads the WinUI shell's %APPDATA% stores
(parity tests pin both serialized shapes), Settings gains adapter/hdr_enabled
(serde-defaulted; Linux stores unaffected).
- pf-presenter: builds on Windows — dmabuf module Linux-gated; SDL keyboard grab
while captured (Alt+Tab/Win reach the host); pick_device ranks discrete over
integrated (device 0 was the iGPU on hybrid boxes — the silent footgun) and
honors PUNKTFUNK_VK_ADAPTER (the Settings GPU pick, exported by the session).
- run loop: block in one SDL wait woken by input AND decoded frames (a per-
session forwarder pushes a FrameWake user event) instead of a 1 ms poll —
measured 111%% -> 5%% of a core (NVIDIA), 86%% -> 3.5%% (AMD), stats unchanged.
The pump's decode-fence wait became once-per-window sampling (no per-frame
pipeline stall; the stat now shows true backlog).
- pf-console-ui: builds on Windows (skia-safe msvc prebuilts); font lookup falls
through fontconfig aliases to concrete DirectWrite families (Consolas/Segoe UI)
— browse/coverflow works, verified against a live host.
- WinUI shell: session-always via new src/spawn.rs (GTK spawn.rs port —
CREATE_NO_WINDOW, stdout contract, kill handle); the Stream screen is a status
card (chips + stage lines from the child's stats). The legacy in-process
D3D11VA path stays behind Settings "Streaming engine" / PUNKTFUNK_BUILTIN_
STREAM=1 as the A/B baseline until Phase 8 deletes it. SessionParams.video_caps
makes the HDR toggle real.
- clients/linux-session renamed to clients/session (builds for both OSes).
- CI/MSIX: both workflows build/test both bins with widened path filters; the
MSIX ships punktfunk-session.exe. ARM64 session builds --no-default-features
(rust-skia has no aarch64-pc-windows-msvc prebuilts; flip when it does).
A/B on this box (5120x1440 HEVC vs home-worker-5): NVIDIA Vulkan 130 fps / 8 ms
e2e / 1.6 ms decode — clearly better than the built-in path. The AMD iGPU VCN
saturates at ~52 fps where its own D3D11VA does ~70 — Adrenalin Vulkan decode is
slower on APU silicon; discrete RDNA validation gates Phase 8.
