enricobuehler	24fa018c70	chore(encode/windows): AMF forensics knobs — PUNKTFUNK_AMF_USAGE + PUNKTFUNK_FFWIN_POLL_MS ... The blocking poll landed but wait_us pegs at exactly the 2-frame-period cap: AMF holds the AU ~2 frame periods regardless of retrieval. Field knobs to bisect on-box (usage preset × poll cap) without rebuild cycles. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-03 14:39:36 +00:00
enricobuehler	51a6ca7e02	fix(encode/windows): AMF latency — honor the loop's blocking-poll contract + preset polish ... The session loop's pipeline deferral was designed around direct NVENC, whose poll() BLOCKS in lock_bitstream; libavcodec's AMF wrapper is truly async (EAGAIN until the ASIC finishes), so a single non-blocking receive quantized AU retrieval to the submit cadence: +1–2 frame periods flat (~43 ms p50 at 720p60 on the Ryzen iGPU vs ~3.5 ms of actual encode). FfmpegWinEncoder now tracks in-flight frames and, while an AU is owed, spin-polls with short sleeps bounded to ~2 frame periods (an overloaded encoder degrades to next-tick pickup instead of stalling capture). Also: quality=speed (latency-first, iGPU-class VCN), explicit bf=0 (h264_amf defaults >0 on RDNA3+), AMF low-latency submission mode (FFmpeg ≥6.1, ignored on older).

enricobuehler	b9fde03f1e	feat(security): finish Windows firewall Public opt-in wiring + vuln-disclosure + doc cleanup ... Firewall (the service.rs core landed in efb1ba2): scope the web-console rule (TCP 47992) to Domain+Private by default with a `--allow-public-network` opt-in that deletes-then-re-adds the rule, and add the installer "Allow connections on Public networks" task (unchecked) forwarding the flag to `service install` and `web setup`. Default is now trusted-networks-only; Public is explicit. Vulnerability disclosure: SECURITY.md (report to security@punktfunk.com, scope, SLAs, safe harbor), a Gitea issue-template contact link, a README security line, and a Reporting section on the docs Security page. Docs: the Security page now documents the Private/Domain firewall default (and how to fix a misclassified-Public network / opt in); removed internal design-doc and CLAUDE.md links from the user-facing docs.

enricobuehler	efb1ba26d7	fix(windows): opt-in pad-driver file logs + size-capped service log rotation ... Two disk-write fixes: - pf-xusb/pf-dualsense no longer write C:\Users\Public\pf*-driver.log unconditionally — the file log is now opt-in (debug builds, or the PFXUSB_DEBUG_LOG / PFDS_DEBUG_LOG system env var), mirroring the audit-§4.4 fix pf-vdisplay already got: a release driver never writes the world-writable Public file (info-leak/DoS surface), and the per-report OUTPUT/SET_STATE hex dumps stop being a sustained per-rumble disk-write path during gameplay. OutputDebugStringA stays unconditional; the host's driver-silence WARN and the gamepad-driver-health failure-mode table now say the log is opt-in. - service.log/host.log get one-generation rotation: at each (re)open a file over 10 MB is renamed to .old, so a crash-restart loop or a RUST_LOG=debug left in host.env can't grow the append-forever logs without bound. Rotation runs only before an open (never under a live appender — host.log's handle lacks FILE_SHARE_DELETE, so a racing rename harmlessly fails). Windows CI compile/clippy pending (drivers workspace + host are not Linux-cross-checkable); rides along with the next pad-driver redeploy.

enricobuehler	1be83575b6	feat(host/windows): "Punktfunk Host" identity in Task Manager (icon + version info) ... punktfunk-host.exe embedded no icon or version resources, so Task Manager and Explorer showed a bare lowercase exe name with a generic icon. build.rs now embeds the branded .ico + FileDescription "Punktfunk Host" / ProductName "Punktfunk" via winresource (same pattern as the Windows client and the tray; Linux packaging builds skip the block). The tray gets a matching "Punktfunk Tray" description, and the SCM display name moves off lowercase "punktfunk streaming host" to "Punktfunk Host" (applied idempotently by `service install` on upgrade).

enricobuehler	d285d4a0b2	fix(tray): live-probe the web console instead of sniffing the install layout ... The "Open web console" entry was gated on {exe dir}\web\web-run.cmd (Windows) / the punktfunk-web unit file (Linux) — which misses consoles run from a repo checkout (the RTX box, caught on-glass) and shows a dead entry while an installed console is stopped. The poller now probes https://127.0.0.1:<web port>/ each cycle (any HTTP response = up, transport failure = down) and the menu follows live on both platforms.

enricobuehler	8005b11faf	feat(tray): system-tray status icon for the host (Windows + Linux) ... New crates/punktfunk-tray — a small per-user companion showing the host service state at a glance (running / stopped / starting / degraded / failed + the live session in the tooltip) with one-click actions: open web console, approve a pending pairing request, start/stop/restart, open logs. No more digging through logs to learn whether the service came back after a reboot or an update. Status is service-manager-FIRST (SCM / systemd user unit — a port squatter can never fake Running), then the new loopback-only unauthenticated GET /api/v1/local/summary (counts/booleans only; the mgmt token and cert.pem are SYSTEM/Admins-DACL'd on Windows, so a non-elevated tray cannot bearer-auth). Windows: windows_subsystem binary (a console exe in the Run key would flash a terminal at sign-in), Shell_NotifyIcon + hidden window, per-session single instance, TaskbarCreated re-add, --quit for the uninstaller; service actions elevate per click via ShellExecuteW "runas" onto the new `punktfunk-host service restart` (stop → wait Stopped → start). Linux: ksni/StatusNotifierItem over zbus, systemctl --user actions (no polkit), /etc/xdg/autostart entry whose --autostart self-gates to actual host users. Icons: scripts/gen-tray-icons.py (pure stdlib) renders the brand lens + status dot into committed .ico/hicolor assets; deb/rpm/arch ship binary+autostart+icons. Live-validated: Linux on the headless KDE session (SNI registration, state transitions, menu-driven start, dbusmenu layout); Windows on the RTX box (session-1 launch with no NIM_ADD failure, single instance, --quit, restart round-trip, summary loopback-200/LAN-401).

enricobuehler	01fcb01019	fix(encode/windows): resolve NVENC at runtime — AMD/Intel hosts no longer crash at start ... The nvenc build linked nvEncodeAPI64.dll's entry points at load time, so a --features nvenc binary hard-crashed on any box without the NVIDIA driver (AMD/Intel). Entry points now come from a runtime LoadLibrary table (encode/windows/nvenc.rs load_api); a missing DLL just falls through the encoder auto-detect to AMF/QSV/software. The generated import lib and all its plumbing (gen-nvenc-importlib.ps1, nvenc.def, PUNKTFUNK_NVENC_LIB_DIR, setup-build-env wiring) are gone. Live-validated on the RTX 4090 box (NVENC session, 7000+ frames). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-03 12:09:18 +00:00
enricobuehler	95a08e99c3	feat(host/windows): seal the host↔driver channels (frame + gamepad, proto v2) ... Frame ring (pf-vdisplay) and both gamepad SHM channels move off named Global\ objects (openable by any sibling LocalService) to UNNAMED sections/events whose handles the host DuplicateHandles into the driver's verified WUDFHost with least access — frame delivery over the SYSTEM+admins-only IOCTL_SET_FRAME_CHANNEL, pads over a 32-byte named bootstrap mailbox (pid + handle value only, DoS-bounded; HID minidrivers have no control device). Driver-validated pad_index kills cross-pad redirects; v1↔v2 mixes fail closed with diagnosis logs on both sides. Sibling-LocalService denial proven empirically (design/idd-push-security.md, design/gamepad-channel-sealing.md). Driver-side raw ops now live behind pf-umdf-util (checked shm accessors, the forbid(unsafe_code) ChannelClient state machine, WDF request tokens) — the pad drivers' logic is 100% safe Rust; whole drivers workspace clippy-gated in CI. driver install --gamepad now sweeps SWD\punktfunk phantom devnodes: a re-created SwDevice REVIVES the old devnode with its previously-bound driver (never re-ranks), so an upgrade otherwise leaves the old driver serving — or, across the v1→v2 fence, a dead pad (found live on the RTX box). On-glass validated on the RTX 4090 box: frame path 7007 frames p50 2.06 ms cross-machine; DualSense + XUSB "sealed pad channel mapped"/proto=2 attach via both the test harness and a real streaming session; phantom-sweep repro.

enricobuehler	6686fcdded	fix(gamestream/tests): sender_delivers_batches flaked under CI load — burst overflowed the default socket buffer ... The test burst 3×100 1200 B datagrams into an undrained loopback socket: at ~2.5 KB kernel truesize each, the default ~212 KB rmem holds only ~80, so on a starved CI runner (parallel release builds) the kernel silently dropped the overflow and the recv loop could never reach 300 — surfacing as WouldBlock after the 3 s timeout. Size the burst (3×20) to fit the default buffer even with zero concurrent draining, and give recv a starvation-tolerant 10 s.

enricobuehler	be879c946a	fix(host/logs): mdns-sd noise gate + tracing-log target normalization in the log ring ... log-crate events arrive through the tracing-log bridge under the shim target "log" — normalize them back to the real module path (NormalizeEvent) so the console's target column and the noise gate see mdns_sd::… , and suppress the bridge's log.* bookkeeping fields like the stderr fmt layer does. Gate known-chatty third-party DEBUG targets (mdns-sd DEBUG-logs every unparseable multicast packet — one AirPlay device floods thousands of entries per hour) to INFO-and-up in the ring, so ambient LAN noise can't evict the tail the ring exists to preserve. stderr under RUST_LOG is unaffected.

enricobuehler	861da54066	feat(web,host/windows): move the web console off :3000 to :47992 ... Port 3000 collides with half the dev-server ecosystem; 47992 sits next to the mgmt API (47990) in the punktfunk port family. Updates the run scripts, systemd/scheduled-task units, Dockerfile, Windows firewall rule + installer, packaging, and every doc that referenced :3000.

enricobuehler	0c17343a50	fix(mgmt): version-agnostic OpenAPI drift test + regenerate the 0.5.0 snapshot ... The snapshot comparison now normalizes info.version on both sides and compares structurally — a version bump alone can never invalidate the checked-in spec again (the 0.5.0 release tripped on exactly this; the API surface is what drift-control protects). Snapshot regenerated so the docs-site copy shows the current version. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-02 17:53:33 +00:00
enricobuehler	9a58746aa5	fix(host/windows): clippy while_let_loop in the async poll drain ... The rebase onto main picked up the pre-fix loop{match} variant of the async retrieve drain — the exact shape the Windows clippy gate rejects (run 6722 failed on it; the while-let form passed run 6724 on the CI branch). Restore the gated form. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-02 17:31:45 +00:00
enricobuehler	c21549c136	feat(host/windows,drivers): gamepad driver attach/heartbeat health surfaced in logs ... The gamepad drivers have no IOCTL plane (hidclass gates the stack), so until now the host had ZERO visibility into whether a driver ever bound: a pad could be "created" with no driver installed and nothing was logged. Two health fields are carved from reserved shm space (layout-compatible; pf-driver-proto pins the offsets): driver_proto — stamped by pf-xusb at device add + per serviced XInput IOCTL (movement = the game-visible path) and by pf-dualsense/DS4 from its ~125Hz timer — and driver_heartbeat. Host-side, every pad owns a DriverAttach watcher fed from the existing service() poll: INFO on attach (WARN on proto mismatch), and after 3s of silence ONE diagnosis WARN combining a cached pnputil /enum-drivers store check, the devnode's CM problem code (CM_Locate_DevNodeW/CM_Get_DevNode_Status on the instance id now captured from the create callback, with plain-language hints: 28 = not installed, 52 = signature/Memory Integrity, …) and the driver's debug log path. Also fixes a real bug both SwDeviceCreate wrappers shared: the 10s WaitForSingleObject result was ignored and the callback HRESULT zero-initialised, so a PnP timeout read as SUCCESS (now E_FAIL init + explicit timeout error). Failure-mode table: design/gamepad-driver-health.md. Linux workspace green; Windows host + drivers CI-compile only, on-box recipe at the bottom of the design doc.

enricobuehler	8af1a15aa6	feat(host,web): host log ring + GET /api/v1/logs + console Logs page ... Remote debugging without shell access: a tracing layer tees every event at DEBUG-and-up — independent of the RUST_LOG filter gating stderr/host.log, so console-side debugging never needs a restart — into a bounded in-memory ring (log_capture.rs, 4096 newest entries, OnceLock singleton like config()), installed at both init sites (stderr path in main, the Windows service file path). The mgmt API serves it cursor-paged at GET /api/v1/logs?after=&limit= — bearer-only and deliberately NOT on the mTLS cert allowlist (log lines can name client identities and host paths). The web console grows a Logs page (follow/pause · min-level filter · text search · eviction-gap badge); polling self-paces: a non-empty page advances the after-cursor (new query key → immediate refetch, drains backlogs), an empty page idles at the 2s interval. OpenAPI regenerated; ring pagination/eviction, layer wiring, and the authed route are unit-tested; Storybook story included.

enricobuehler	1a483aae06	feat(host/windows): two-thread async NVENC retrieve (PUNKTFUNK_NVENC_ASYNC, opt-in) ... The gpu-contention plan's §5.B lever: today submit and the blocking lock_bitstream share one thread, so under a GPU-saturating game the pipeline serializes on the WDDM scheduling wait (1000/17ms ≈ 59fps — the depth-1 collapse; the old 'deeper pipeline just stacks latency' result was a same-thread implementation, not a disproof). Async mode opens the session enableEncodeAsync=1, registers an auto-reset completion event per pool bitstream, and moves the wait+lock+copy+ unlock onto an internal retrieve thread feeding poll() through a channel — the exact split the NVENC guide mandates. Register/map/unmap stay on the encode thread; teardown drops the job channel, joins the thread, THEN destroys the session. In-flight depth is bounded by PUNKTFUNK_NVENC_ASYNC_DEPTH (default 4, hard cap POOL-1) — both for output-buffer reuse and because NVENC encodes the capture ring's textures in place. Idle latency cost ≈ 0 (same-tick pickup); under contention completed frames queue instead of stalling capture. CI-compile validated only — on-glass A/B under game load on the RTX box still pending (box offline). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-02 16:33:56 +00:00
enricobuehler	49e6021ece	feat(host,probe): controlled loss injection for the native path + probe keyframe-on-drop ... PUNKTFUNK_VIDEO_DROP now also covers the native data plane (N% of sealed wire packets discarded before send in paced_submit — the same FEC-test knob the GameStream path has; no netem/root needed), and the probe grows the real clients' recovery trigger: the data loop publishes the session's unrecoverable-frame count and the control task sends RequestKeyframe when it rises (100ms poll = natural coalescing). Together these make the IDR-vs-intra-refresh recovery A/B runnable against any host. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-02 16:33:56 +00:00
enricobuehler	fa4c798a25	feat(host/linux): amdgpu session clock pin — gpuclocks grows the AMD arm ... nvclocks.rs -> gpuclocks.rs. PUNKTFUNK_PIN_CLOCKS=1 now also pins every amdgpu card's power_dpm_force_performance_level to high for the host lifetime (prior level restored on exit) — the measured AMD encode- latency lever: VCN per-frame time doubles when a 60fps paced trickle lets clocks sag (8 -> 4.4ms/frame at 1440p on the 780M with clocks hot). Root-gated by sysfs ownership; non-root degrades to a logged recipe (validated live on the AMD box). Opt-in stays deliberate: box-wide power-management override, wrong on battery/Deck.

enricobuehler	fd1086074b	feat(host/vaapi): submit-split instrumentation + async_depth knob (depth 1 stays default) ... Chasing the 8ms submit at 1440p on the 780M: the sampled PUNKTFUNK_PERF split (push/pull/send) shows desc+buffersrc at ~5us, hwmap-import+VPP CSC at ~0.2-0.5ms, and avcodec_send_frame owning the rest — so neither a VA-surface import cache nor CSC overlap would help. Two facts landed: (1) async_depth>=2 in libavcodec's vaapi_encode is a structural +1-frame latency (frame N's packet only materializes when N+1 queues; measured 18ms vs 8.3ms p50 at depth 1) — depth 1 stays the default, PUNKTFUNK_VAAPI_ASYNC_DEPTH exists for pixel rates beyond the ASIC's serial budget, and poll() now does a bounded in-flight wait so a deeper depth still ships the AU as soon as the ASIC finishes. (2) The residual send_frame block tracks GPU CLOCKS, not the ASIC: ~8ms/frame at a 60fps duty cycle vs ~4.4ms at 120fps pacing vs 3.5ms back-to-back (270fps CLI benchmark, even at -async_depth 1) — the clock-sag fix lands in gpuclocks.

enricobuehler	12a3944156	feat(host/linux): default the tiled zero-copy path to GPU NV12 (NVENC fed native YUV) ... A/B'd on the Bazzite box (RTX 5070 Ti, KWin 6.6, driver 595, 1080p60 over the LAN): pixel-correct decode (full desktop, no tint/banding), latency-neutral idle (p50 1.47ms RGB vs 1.52ms NV12, both 2400/2400 frames), CPU-neutral — and it deletes NVENC's internal RGB->YUV CSC from the SM/3D engine a game saturates (video 40%+SM 15% -> video 26%+SM 2% measured on Windows). Matches the Windows host default. PUNKTFUNK_NV12=0 restores the RGB feed; LINEAR/gamescope captures are unaffected. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-02 16:33:56 +00:00
enricobuehler	73f14bc725	feat(host/linux): NVIDIA clock hygiene — P2-cap driver profile + opt-in NVML clock floor ... Two halves of the easy-scene p99 lever (host-latency plan Tier 1B): CudaNoStablePerfLimit application profile (no root; NVIDIA's supported opt-out of the CUDA/NVENC P2 memory-clock clamp, raw key 0x166c5e=0 per open-gpu-kernel-modules#333, shipped for obs/Discord in R595) installed into ~/.nv/nvidia-application-profiles-rc.d/ keyed on procname, opt-out PUNKTFUNK_NV_PROFILE=0; and PUNKTFUNK_PIN_CLOCKS=1 arming an NVML SetGpuLockedClocks(TDP, UNLIMITED) core-clock floor (base floor, boost headroom — never a max pin) held for the host lifetime, reset-on-start self-healing a crashed run's stale pin, NO_PERMISSION degrading to a logged sudoers/oneshot recipe. libnvidia-ml is dlopen'd like libcuda — no link-time dependency, clean no-op off NVIDIA.

enricobuehler	21eded8d88	feat(host): intra-refresh loss recovery + delivery-anchored latency instrumentation ... Intra-refresh (opt-in PUNKTFUNK_INTRA_REFRESH=1 until on-glass validated): NVENC runs a moving intra band + recovery-point SEI (gop_size becomes the wave period, ffmpeg forces the real GOP infinite; default fps/2, PUNKTFUNK_IR_PERIOD_FRAMES overrides; ENOSYS latches a fallback to IDR-only). Clients request a keyframe on every FEC-unrecoverable frame, so under intra-refresh the session glue serves the first request instantly and suppresses the rest for a 2s window — the wave heals loss without the 20-40x IDR spike cascade. VAAPI/software keep IDR recovery. Instrumentation: the wire pts now anchors at the PipeWire delivery stamp (client-measured latency covers delivery + queue age, not just submit->glass; repeats/synthetic stamps fall back to now), encode_us keeps its submit->AU meaning via a separate inflight stamp, and a new 'queue' stage (delivery->submit age of fresh frames) rides PUNKTFUNK_PERF and the web-console stats samples.

enricobuehler	315eb6ef7c	feat(host/gamestream): priority-boost the video + send threads like the native path ...

enricobuehler	a333d5a15b	feat(host/capture): zero-copy by default on VAAPI hosts (dmabuf passthrough) ... PUNKTFUNK_ZEROCOPY unset now defaults ON when the encode backend is VAAPI — a stock AMD/Intel install gets the LINEAR-dmabuf -> GPU-CSC path instead of three full-frame CPU touches (measured on the 780M at 1440p: 0.8s vs 7.9s CPU per 600 frames, pixel-identical). NVENC stays opt-in. A dmabuf offer the compositor never accepts latches a one-shot downgrade so the pipeline rebuild renegotiates on the CPU offer; explicit =1 keeps erroring loudly. The EGL->CUDA importer is no longer built on VAAPI backends (an NVIDIA box forced to PUNKTFUNK_ENCODER=vaapi now correctly takes the passthrough instead of producing CUDA frames the encoder rejects), and a VAAPI session landing on the CPU path warns with the reason.

enricobuehler	34bdda7d96	feat(host/vaapi): fall back to the low-power (VDEnc) entrypoint — unblocks modern Intel ... Gen12+/Arc iHD exposes ONLY EncSliceLP, so the default open fails with 'no usable encoding entrypoint'. Try full-feature first (AMD unchanged, validated on the 780M), retry low_power=1, cache the mode per codec; PUNKTFUNK_VAAPI_LOW_POWER pins it. Probes inherit the ladder.

enricobuehler	5ef63756ea	fix(host/linux,clients/android): honor the host/device keyboard layout in keymaps ... wlroots injector: the virtual keyboard keymap now defers to the standard XKB_DEFAULT_RULES/MODEL/LAYOUT/VARIANT/OPTIONS env vars (libxkbcommon built-ins as fallback) instead of hardcoding evdev/pc105/us, matching the libei path where the session compositor's own keymap applies.

enricobuehler	2c416a4bff	fix(host/windows): layout-correct keyboard injection - semantic vs positional VKs ... First-party punktfunk clients send US-positional VKs (the physical key's US-layout VK), GameStream/Moonlight clients send layout-semantic VKs (Sunshine's model). The SendInput injector previously resolved everything through the SYSTEM service's layout - on a German host that is the y/z swap and u-umlaut-on-o-umlaut scramble. GameStream ingest now tags its key events KEY_FLAG_SEMANTIC_VK (stripped from punktfunk/1 wire events so a network client can't flip the convention); the injector maps semantic VKs under the foreground app's layout and positional VKs through a fixed scancode table.

enricobuehler	019f2677a7	feat(host,web): multi-GPU selection — GPU inventory + preference API, web-console GPU card ... - new crate::gpu (compiled on all platforms so the OpenAPI doc stays platform-independent): DXGI / sysfs GPU inventory with reboot-stable ids (PCI vendor:device + occurrence — LUIDs are per-boot), persisted auto/manual preference (<config>/gpu-settings.json, atomic temp+rename with in-memory rollback), one selection with precedence console preference > PUNKTFUNK_RENDER_ADAPTER > max VRAM and graceful fallback when the preferred GPU is absent, plus a live "in use" record (RAII session guard wrapped around every encoder open_video returns) - fix: windows_gpu_vendor derived the encoder backend from DXGI adapter 0 instead of the selected render adapter — on a hybrid box (e.g. Intel iGPU at index 0 + NVIDIA dGPU) the backend could disagree with the GPU the capture ring / IddCx render pin sit on. The NVENC 4:4:4 probe now also runs on the selected adapter (was: OS default), the codec/4:4:4 probe caches are keyed per selected GPU (were process-lifetime OnceLocks), and an explicit PUNKTFUNK_ENCODER conflicting with the selected GPU's vendor warns up front - mgmt API: GET /api/v1/gpus (inventory + mode + preferred + next-session selection with reason + in-use GPU/backend/session-count) and PUT /api/v1/gpus/preference (validates mode/gpu_id before writing); openapi.json regenerated; the vdisplay render pin now also engages for a console preference (not just the env pin) - web console: GPU card on the Host page — list with vendor + VRAM, Automatic / Prefer controls, Preferred / Next session / "In use · backend" badges, missing-preferred-GPU warning and env-pin note; en + de messages - Linux: a matched manual preference picks the VAAPI render node and the NVENC-vs-VAAPI auto choice; auto mode is exactly the previous behavior Validated live on the hybrid laptop (RTX 3500 Ada + Intel Arc Pro, which enumerates twice — the occurrence ids disambiguate): enumerate, prefer, bad-id 400, restart persistence, auto-restore keeping the stored pick.

enricobuehler	f48dc5dfce	feat(host/windows,packaging): installer overhaul - branding, VB-CABLE, GameStream choice, driver uninstall ... - Modern branded wizard: WizardStyle=modern dynamic windows11 (Inno >= 6.6, plain-modern fallback for older compilers; CI provisioning upgrades a pre-6.6 Inno). Brand-mark wizard side panels + header tiles (100-200% DPI) and a multi-size punktfunk.ico (SetupIconFile + Apps & Features), generated AND committed by branding/gen-branding.ps1 from the canonical brand geometry. Gotcha encoded in the script: ISCC rejects all-PNG icons, so entries <= 64px are classic DIBs (PNG only at 128/256), and the ICO is load-verified. - VB-CABLE actually ships now: windows-host.yml never set VBCABLE_DIR, so every published installer silently omitted the virtual mic (broken mic passthrough in the field). CI provisions the pinned, SHA-256-verified official Pack45 (provision-windows-punktfunk-extras.ps1) and the pack now FAILS on a supplied-but-invalid dir instead of shipping mic-less again. Attribution per VB-Audio's bundling grant surfaced in the visible wizard task text (vendor, vb-cable.com, donationware) on top of the licenses notice. - GameStream (Moonlight) compat is a wizard task (checked by default) -> service install --gamestream=on|off writes PUNKTFUNK_HOST_CMD= serve[ --gamestream] into host.env. Only the two canonical values are ever rewritten - a hand-customized command line survives upgrades. Silent installs: /MERGETASKS="!gamestream". - Driver uninstall (field report: our virtual-device drivers survived uninstall): new `driver uninstall [--gamepad]` removes the pf-vdisplay device node(s) + the pf-vdisplay/pf-dualsense/pf-xusb driver-store packages, wired into [UninstallRun] after service uninstall. Locale-safe by construction: devices matched on unlocalized VALUES (never pnputil's localized labels), packages found by INF content scan - validated against a German-locale box ("Instanz-ID:" parse; 7/7 punktfunk INFs matched, no foreign hits). VB-CABLE is deliberately left installed (shared third-party component with its own uninstaller). Installer compile, cargo check/clippy/fmt, and the ASCII locale gate are green; the wizard look + uninstall flow still need one on-glass pass on a disposable box (this box runs the live host).

enricobuehler	133e25849d	feat(apple): gamepad UI v2 — controller settings + add host, aurora, macOS ... Sources reorganized (client: Home/Session/Settings/Stores/Support/Trust; kit: Audio/Connection/Gamepad/Input/Support/Video/Views) with the big files split along the same seams. The gamepad mode is couch-complete, and now on macOS too (the living-room Mac case), not just iOS/iPadOS: - GamepadSettingsView: a console-style, fully controller-navigable settings screen (X from the launcher) — up/down moves focus, left/right steps values (clamped, boundary thud), A cycles/toggles, B closes; the focused row shows a one-line description. Backed by GamepadMenuList, the vertical sibling of GamepadCarousel, and SettingsOptions — the option lists hoisted out of SettingsView statics and shared by the touch, tvOS and gamepad settings. - GamepadAddHostView + GamepadKeyboard: register a host end to end with a pad — field rows open an on-screen controller keyboard (dpad grid, A types, X backspaces, B done); the launcher carousel ends in an Add Host tile, so the dead-end "add one with touch first" empty state is gone. - Launcher polish: contextual hint bar with the pad's real button glyphs, controller name + battery chip, one shared console chrome. - GamepadScreenBackground: an animated aurora (TimelineView-driven drifting blobs in the brand's violet family, breathing radii, slow hue shift, legibility scrim; freezes under Reduce Motion). Pure SwiftUI on purpose — a .metal library only bundles reliably in one of the two build systems (SPM vs the xcodeproj's synced folders) these sources compile under. - macOS port: settings/add-host/library present as sized sheets (a macOS sheet takes its content's IDEAL size, and the GeometryReader-driven screens collapsed to nothing), NSScreen-based mode lists, scroll indicators .never (the "always show scroll bars" setting overrides .hidden), tray scrims so scrolled rows dim under the pinned title/hints, extra title clearance, and a PUNKTFUNK_FORCE_GAMEPAD_UI=1 dev hook — launcher/settings/add-host/keyboard/ library render-verified live on a real Mac + LAN hosts. - GamepadMenuInput: X button support, and (re)start now snapshots held buttons so a controller handoff press never fires twice (the B that closed the keyboard no longer also cancels the screen underneath). - Cleanups: one "Connection failed" alert in ContentView instead of one per home screen; HostDiscovery.advertises/unsaved shared by both home screens. - host: can_encode_444 stub for the non-Linux/Windows host build (the macOS synthetic-source loopback used by the Swift tests).

enricobuehler	12843fe253	feat(protocol,clients): codec preference negotiation + Linux client decodes per Welcome (Phase 2a) ... Adds a client-selectable **preferred codec** and wires the core + ABI + probe + Linux client to negotiate and decode it. (Windows/Apple/Android follow in 2b.) **Core:** - `Hello.preferred_codec` (a single CODEC_* bit, 0 = auto) — a soft hint appended after `video_codecs`. `resolve_codec(client, host, preferred)` now honors the preference when the host can also emit it, else falls back to precedence (HEVC > AV1 > H.264). Roundtrip + preference tests. - `NativeClient::connect` takes `video_codecs` + `preferred_codec`; `NativeClient.codec` exposes the resolved `Welcome.codec`. - ABI: `punktfunk_connect_ex7` (adds the two codec params; `ex6` delegates to it advertising HEVC-only) + `punktfunk_connection_codec` getter + `PUNKTFUNK_CODEC_{H264,HEVC,AV1}` constants (drift-guarded against the wire values). Header regenerated. **Host:** passes `hello.preferred_codec` into `resolve_codec`. **probe:** `--codec h264|hevc|av1|auto` sets the preference (still advertises it can decode all three); the dump extension already follows the resolved codec. **Linux client:** advertises the codecs FFmpeg can actually decode (`decodable_codecs()`), threads the user's `codec` setting as the preference, and builds the decoder — both the software and VAAPI paths, plus the mid-session VAAPI→software demotion — from the negotiated `Welcome.codec` instead of hardcoding HEVC. New "Video codec" dropdown in Preferences (Automatic/HEVC/H.264/AV1). Live-validated on the dev box: probe `--codec hevc` against a software (H.264-only) host resolves to H.264 (graceful soft-preference fallback), no failure. clippy + core (57) + host (133) tests green.

enricobuehler	ffc0b07b46	feat(protocol,host): negotiate video codec + add a GPU-less software (openh264) encode path ... Phase 1 of codec negotiation, and the Linux software H.264 encode path it unblocks. **Codec negotiation (core `quic`):** - `Hello.video_codecs` (bitfield: CODEC_H264/HEVC/AV1) — the client advertises what it can decode; appended as a trailing byte (older client → 0 = HEVC-only, back-compat). - `Welcome.codec` — the single codec the host resolved and will emit; trailing byte (older host → HEVC). - `resolve_codec(client, host_capable)` picks the shared codec (precedence HEVC > AV1 > H.264) or `None` → the host refuses honestly rather than sending an undecodable stream. - Roundtrip + back-compat tests; cbindgen exports the CODEC_* constants. **Software encoder (host):** - The openh264 `OpenH264Encoder` (was Windows-only) is now built on Linux too — it's platform-agnostic (consumes CPU RGB `CapturedFrame`s, statically-bundled openh264). `openh264` moved to the shared linux+windows Cargo target. - `PUNKTFUNK_ENCODER=software` selects it: `open_video` gains a `software` branch (H.264 only), and `session_plan::resolve_encoder` / `capture::gpu_encode` resolve `EncoderBackend::Software` → `output_format().gpu = false`, so the portal capturer delivers CPU RGB. Explicit-only (auto never picks it — a box with a dead driver still has /dev/nvidiactl and would mis-resolve NVENC). **Host codec resolution (`punktfunk1`):** - The native path no longer hardcodes HEVC: it resolves the codec from the client's advertised set ∩ the host's capability (`Codec::host_wire_caps`: software→H.264, else HEVC), threads it through `SessionPlan.codec`, and opens the encoder + validates reconfigures at that codec. A software host + HEVC-only client is refused with a clear error. - 4:4:4 is gated on HEVC (it's HEVC-only). **Probe:** advertises H264|HEVC|AV1 and logs the resolved codec. Validated on the GPU-less dev box: negotiation is live end-to-end (probe advertises 0x07 → host resolves H.264 → Welcome reports it → plan = Software/H264), and the openh264 unit test (CPU RGB → AnnexB IDR) now runs on Linux. Full capture→encode still needs a GPU on this box — every compositor screencast path (KWin GL, gamescope VK_EXT_physical_device_drm, wlroots EGL) requires one; software render (llvmpipe/pixman) can't be captured — so this box exercises negotiation + encoder, not live capture. The software path unblocks GPU-less-*encode* boxes that still have a display GPU. Phase 2 (clients advertising real codecs + decoding per Welcome.codec) is a follow-up.

enricobuehler	e7b07d2363	fix(host): make client game launches work on every Linux compositor ... Client-initiated launches (Hello.launch / GameStream applist) were only wired to gamescope's bare-spawn path via the process-global PUNKTFUNK_GAMESCOPE_APP env — which leaked across sessions, was never read by kwin/mutter/wlroots (launch was a silent no-op there), and was unreachable on gamescope anyway because apply_input_env unconditionally defaulted to the managed session (which bails on non-Bazzite/SteamOS boxes and ignores the launch command in all its modes). - Thread the launch per-session: resolve the library id at handshake, carry it on SessionContext (Windows: id; else: resolved command), and hand it to the backend instance via set_launch_command — the global env write is gone (the env stays as an operator fallback in spawn). - Gamescope sub-mode ladder (pick_gamescope_mode, pure + unit-tested): managed only when session-plus/SteamOS infra exists, attach for an explicit request or a foreign (non-host-descendant) gamescope, else bare spawn — which nests the launch and is now reachable on plain distros instead of the guaranteed managed-mode bail. - launch_session_command: one launch entry point for both planes once capture is live — desktop compositors plain-spawn into the retargeted session (the virtual output is primary); managed/attached gamescope spawns with the live session's DISPLAY/GAMESCOPE_WAYLAND_DISPLAY discovered from /proc (steam:// URIs also forward over Steam's own pipe). launch_is_nested gates bare spawn against double-launching. - GameStream unified onto the same dispatch; also nests library-id picks into gamescope (previously only apps.json cmd was nested). Validated live on the dev box up to the missing-GPU wall: handshake resolution, Spawn sub-mode on plain Ubuntu, gamescope spawned with the command nested. On-glass validation (kwin spawn on the streamed output, Bazzite/Deck managed forward) pending GPU reattach. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-01 22:02:52 +00:00
enricobuehler	7c976bc8c3	fix(host/audio): make the Linux virtual mic the default source (was silent) ... The punktfunk/1 virtual microphone was created as a plain Audio/Source with no session priority, which caused two failures — both diagnosed live against a Bazzite host on PipeWire 1.4.10: 1. It was never WirePlumber's default source, so any app recording the *default* input (games, Discord, arecord) heard silence. This is the Linux analogue of the Windows host forcing the default recording endpoint (audio_control.rs). 2. The real killer on PipeWire 1.4.x: a *non-default* Audio/Source recorded via `--target` never gets a driver assigned — the {source, recorder} group stays orphaned (pw-top QUANT/RATE 0, driver-node None), so the RT process() callback never fires and even an explicitly-selected mic is pure silence. PipeWire 1.6 drives any recorded source regardless, which is why the host worked on a 1.6 box but not the 1.4.10 Bazzite host. Fix: advertise a high priority.session on the source so WirePlumber elects it as the default source and keeps it driven. Reproduced with a faithful standalone copy of the node on the same 1.4.10 daemon: no priority.session -> silent, priority.session set -> audio. Only overrides WirePlumber's auto default; a user's explicit default.configured.audio.source still wins. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-01 21:31:51 +00:00

enricobuehler	ba39b08e09	feat(web): consolidate paired devices, self-contained sections, docs + lint ... Web console - Pairing/Library/Stats refactored into self-contained subsections that each own their own queries + mutations; a shared slot-based layout (view.tsx) is filled by the live page (containers) and Storybook (pure cards + fixtures) so the layout can't drift. - All paired devices in one list on Pairing with a protocol column (punktfunk/1 + Moonlight), routing each unpair to the right endpoint; the redundant Clients page is removed. - Library: overview grid split from the add/edit form into separate files. - Login screen links out to the docs. Docs - "Console login password" section on every host page (apt/RPM/Bazzite/SteamOS/Windows) plus a new "Forgot your Password?" troubleshooting page, linked from the login screen. - Console served as HTTP/1.1 over TLS (drop the unusable HTTP/3 advertising) across the Bun entry, launchers, systemd units, and packaging. Tooling - Biome now respects .gitignore (stops linting generated code), config migrated to 2.5.1; all lint issues fixed cleanly.

enricobuehler	12c7ec9e57	feat(gamestream): advertise HDR + surface the game library (with covers) to Moonlight ... Bring the GameStream/Moonlight plane up to the native plane's capability parity. HDR (Windows only): - New host_hdr_capable() gate (Windows + PUNKTFUNK_10BIT, matching the native policy). serverinfo layers SCM_HEVC_MAIN10 onto the probed/static codec mask, so Moonlight finally offers its HDR toggle (live: mask 0x10101 -> 0x10301). - Parse the client's dynamicRangeMode into StreamConfig.hdr and pass it through to OutputFormat::resolve, so a client HDR request proactively enables advanced color on the per-session virtual display (PQ flows even from an SDR desktop). The encoder bit depth now derives from the captured frame format (gs_bit_depth) rather than a hard-coded 8 that mislabeled the already-Main10 HDR stream. Game library in /applist: - The catalog now layers library::all_games() (Steam/Epic/GOG/Xbox/custom) on top of Desktop/apps.json, each with a STABLE GameStream id (FNV-1a, dedup-probed) and the store-qualified library id. Launch routes through the existing security-reviewed launch_title/launch_command via library::launch_gamestream_library — a client can only pick an existing title, never inject a command. - /appasset cover proxy: Moonlight fetches per-app covers from the host, so resolve appid -> library cover URL and proxy the bytes (portrait -> header -> hero -> logo; data: + bounded http(s) fetch), on a blocking thread. IsHdrSupported reflects the host HDR capability. 4:4:4 stays off on GameStream by design: stock Moonlight is 4:2:0 and the Windows IDD-push capturer can't deliver full chroma yet (capturer_supports_444() == false); the gate is documented so it lights up once IDD-push full-chroma capture lands. Validated live (Moonlight -> Windows NVENC host): HDR advertised, the Epic library shows with covers, launch works. clippy clean; apps/serverinfo/library unit tests cover the HDR mask, stable-id, dedup, and data-URL paths.

enricobuehler	4306d4f914	fix(windows/gamestream): create the virtual display on Windows (Moonlight black screen) ... The GameStream video path (open_gs_virtual_source) ran the Linux compositor- detection state machine on every platform. On Windows detect_active_session() returns None and vdisplay::detect() bails ("could not detect compositor ... XDG_CURRENT_DESKTOP=''"), killing the video thread right after RTSP PLAY — so a Moonlight client paired, negotiated, then black-screened and dropped. The native punktfunk/1 path already guards this (resolve_compositor returns a placeholder Compositor on Windows, since vdisplay::open ignores the compositor arg there and always uses the pf-vdisplay IddCx backend). Mirror that guard in the GameStream path: short-circuit to a placeholder on Windows, keep the Linux session detection (apply_session_env/apply_input_env) under cfg(not(windows)). Validated live: Moonlight -> this box now creates the pf-vdisplay virtual monitor, attaches the IDD-push ring, and NVENC streams 5120x1440@240.

enricobuehler	83ee53290e	feat(windows-host): mic passthrough — auto-wire audio devices + bundle VB-CABLE ... The Windows virtual mic worked only with manual Sound-settings fiddling: on a headless host (no real audio output) BOTH the desktop-audio loopback and the virtual mic must run on virtual cables, and on DIFFERENT ones or the loopback re-captures the injected mic (echo). The Steam pair gives only one usable cable (Steam Streaming Speakers loopback is silent — validated), so the mic + loopback collided and echoed, and when the default playback happened to be the mic device the anti-echo guard reported the mic "unavailable". Host now auto-wires the devices at startup (audio/windows/audio_control.rs, ensure_wired_once, hooked from open_audio_capture/open_virtual_mic): default playback = a loopback-capable render that is NOT a cable and NOT the dead Steam Speakers (real output > Steam Streaming Microphone); default recording = the mic capture (VB-Cable "CABLE Output" preferred). Uses a hand-rolled IPolicyConfig vtable (the only way to set a default endpoint; not in windows/wasapi crates). Opt out with PUNKTFUNK_KEEP_DEFAULT. wasapi_mic candidates now prefer "cable input". Validated live: from a deliberately-wrong start (playback=CABLE Input) the host corrected both default endpoints at the OS level. A Windows audio endpoint can only be created by a kernel-mode driver (no UMDF path — ACX is KMDF-only), so we cannot self-sign our own like the UMDF gamepad/ display drivers. Instead the installer bundles + silently installs the official base VB-CABLE (VB-Audio donationware, vendor-signed → loads with no test-signing, redistributed under VB-Audio's bundling grant): install-vbcable.ps1 (seed the VB-Audio cert into TrustedPublisher, run -i -h) + an installaudiocable task, gated on -VbCableDir/$env:VBCABLE_DIR (the package binary is not in the repo). Attribution in packaging/windows/licenses/VB-CABLE-NOTICE.txt. .iss compiles with the path enabled. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-30 09:09:26 +02:00
enricobuehler	0f798d62b6	feat(windows-host): pf-vdisplay — fix the ADD/REMOVE wedge + per-client display-config persistence ... Two phases of pf-vdisplay (IddCx virtual display) lifecycle work, both validated on-glass on the RTX box. Phase 1 — fix the long-standing IOCTL_ADD 0x80070490 (ERROR_NOT_FOUND) wedge that ghost-monitor slot-budget exhaustion produced under ADD/REMOVE churn (the reset-script/reboot recurring failure). Validated: 43 reconnect-churn cycles, 0 wedges, monitor-node count flat at 1. * driver: on IddCxMonitorArrival failure, tear the created-but-not-arrived monitor down with WdfObjectDelete + reclaim its id — the asymmetric-with-the-create-failure-path leak that exhausted the 16-monitor MaxMonitorsSupported budget; recover MONITOR_MODES from lock poisoning instead of failing closed (defensive; the driver builds panic=abort). * host: collapse the build-retry churn — hold ONE monitor lease across all build attempts and preempt only on Lingering (not Active), so a cold start does 1 ADD not 8; reap not-present "punktfunk" monitor PDOs on startup (the reset-script step-2 logic, in-process) and self-heal a detected 0x80070490 by reaping + retrying ADD; force-preempt a stuck-Active prior monitor on the begin_idd_setup timeout (the safety net the Lingering-only preempt would otherwise drop). Phase 2 — give each client (keyed by its cert FINGERPRINT) a STABLE virtual-monitor id (1..=15) so Windows reapplies that client's saved per-monitor config (DPI SCALING) across reconnects, and two clients never share/bleed config. Validated: distinct clients -> distinct ids (1, 2); the driver honors the host's id (echoed resolved == preferred). * proto: rename AddRequest._reserved -> preferred_monitor_id (offset 20) and AddReply._reserved -> resolved_monitor_id (offset 12) — byte-compatible (offset asserts), NO PROTOCOL_VERSION bump, so a pre-Phase-2 driver degrades gracefully to auto-id (the host detects it via the resolved echo). * driver: create_monitor honors a host-supplied preferred id via resolve_id (range 1..=15, never collides with a live monitor) and seeds the EDID serial + IddCx ConnectorIndex + ContainerId from it. * host: a persisted LRU fingerprint->id map (%ProgramData%\punktfunk\pf-vdisplay-identity.json), threaded to add_monitor via a set_client_identity no-op trait method (Linux/GameStream unaffected).

enricobuehler	080c55dbf7	refactor(host/windows): collapse Windows capture to IDD-push only ... Remove DXGI Desktop Duplication (DuplCapturer), Windows.Graphics.Capture (WgcCapturer), the two-process SYSTEM+helper relay (virtual_stream_relay / HelperRelay / DesktopWatcher / composed_flip), and the five source files that implemented them. IDD direct-push is now the sole Windows capture path; the session topology is always SingleProcess. Deleted files: wgc.rs, wgc_relay.rs, desktop_watch.rs, composed_flip.rs, windows/wgc_helper.rs (+ wgc-helper subcommand in main.rs). dxgi.rs is kept but carved to shared GPU primitives only (make_device, HdrP010Converter, VideoConverter, install_gpu_pref_hook, WinCaptureTarget, pack_luid) — ~2237 lines of DDA-only code removed; imports cleaned. capture.rs: IDD-push open failure fails the session cleanly (no fallback). Adds capturer_supports_444() — returns false on Windows (IDD-push 4:4:4 is a follow-up), replacing the stale single_process gate in 4:4:4 negotiation. session_plan.rs: CaptureBackend{Dda,Wgc} and SessionTopology::TwoProcessRelay removed. config.rs: no_helper/force_helper/no_wgc/capture_backend/secure_dda removed. merged_env_block relocated from wgc_relay to windows/interactive.rs.

In-process vhci attach (loopback OP_REQ_IMPORT handshake → sysfs attach) with a bounded `usbip`-CLI fallback; detach on drop. - Backed by a vendored, libusb-free trim of the `usbip` crate (crates/punktfunk-host/vendor/usbip-sim, MIT + NOTICE; host/cdc/hid + rusb/nusb removed; interrupt-IN paced by bInterval). - Selection ladder raw_gadget (SteamOS fast-path) → usbip (universal) → UHID, with PUNKTFUNK_STEAM_USBIP / PUNKTFUNK_USBIP_ATTACH knobs. - Shared Deck descriptors + the 0x83/0xAE feature contract + a Steam-accepted serial consolidated into steam_proto.rs; the raw_gadget backend reuses them. - Linux client leave-shortcuts: Ctrl+Alt+Shift+D + holding the escape chord (L1+R1+Start+Select) >=1.5s end the session (short press still exits fullscreen); the chord state resets across sessions. Also bundles in-progress work already staged in the tree: - host(kwin): xdg-output logical-geometry mapping so the KWin fake_input backend places absolute coordinates correctly under display scaling. - docs: design/README index entries + design/controller-only-mode.md.

enricobuehler	963c406f33	feat(host/steam): default the gadget Deck on for SteamOS (glass-confirmed) ... The virtual Steam Deck is validated glass-to-glass on a Deck: it appears as a distinct second Steam controller, a held A drives Steam's overlay ("Resume Game"), and a button press registers in a real game (confirmed in-game). gadget_preferred() now defaults ON for SteamOS hosts (/etc/os-release ID=steamos or ID_LIKE), OFF elsewhere where the universal UHID path stays the default; PUNKTFUNK_STEAM_GADGET=1/0 forces it. A Deck-as-host with a physical Deck never reaches this path — resolve_gamepad's conflict gate degrades SteamDeck → DualSense first, so the two-Deck case never happens in production (it was only a test-rig confound on the dev Deck). The feature is complete: a virtual Steam Deck that Steam Input recognizes + promotes, churn-free, with input flowing to games. Workspace clippy/fmt/test green. Not pushed.

enricobuehler	7ab8acaf55	feat(host/steam): harden the gadget feature contract — fixes the evdev churn ... The virtual Deck's gamepad evdev was churning (destroyed + recreated) because Steam kept re-probing: GetControllerInfo reads HID feature reports, and the gadget served zeros for them. Captured the real contract off a physical Deck (packaging/linux/steam-deck-gadget/get_deck_attrs.c, hidraw HIDIOCGFEATURE — usbmon truncates to 32B) and implemented it in steam_gadget.rs::feature_reply: - 0x83 GET_ATTRIBUTES_VALUES: [83, 2d, 9×(attr-id, u32-LE)] — product id 0x1205, a per-instance unit serial (0x0a/0x04, so a gadget never collides with a real Deck or another gadget), and the capability attrs (0x09=0x2e, 0x0b=0x0fa0, rest 0). - 0xAE GET_STRING_ATTRIBUTE: [ae, len, attr, ascii] — serial (attr 1) / board serial (attr 0). - other commands (0x87 settings): echo the last write. Validated on the Deck: 1 connect / 0 disconnect / 1 gamepad evdev (was constant churn), Steam activates the gadget cleanly (no GetControllerInfo failed, no zombie) and emits its X-Box 360 pad. usbmon on the gadget's bus confirms our state reports (pressed button at byte 8) are delivered on the interrupt-IN and consumed by hid-steam — so with M1/M2's byte-8→BTN_SOUTH decode the input chain is proven end-to-end. Remaining: a foreground-game confirmation of Steam Input's XInput mapping, then default the gadget on for SteamOS. Workspace clippy/fmt/test green. Not pushed.

enricobuehler	c8e19396e4	feat(host/steam): raw_gadget Deck host backend (Steam-Input path, opt-in) ... Port the proven raw_gadget virtual Deck to a Rust host gamepad backend, the SteamOS-only transport that gets Steam Input to actually promote the Deck. - inject/linux/steam_gadget.rs (new): SteamDeckGadget — a userspace raw_gadget emulator of the real 3-interface USB Deck (mouse=0/keyboard=1/controller=2, 28DE:1205) on a dummy_hcd loopback UDC, descriptors captured from a physical Deck, answering every control transfer incl. the HID feature reports. Driven by the same steam_proto::serialize_deck_state as the UHID pad; rumble feedback via parse_steam_output. The raw_gadget UAPI is funneled through 4 documented ioctl wrappers (the crate denies undocumented unsafe). - inject/linux/steam_controller.rs: the manager pad is now a DeckTransport enum (Uhid | Gadget); ensure() prefers the gadget when PUNKTFUNK_STEAM_GADGET=1 (best-effort modprobe dummy_hcd+raw_gadget), gracefully falling back to the universal UHID SteamDeckPad. write/pump/heartbeat dispatch through the enum. Validated on a real Deck via a static musl harness that #[path]-includes the module: enumerates, hid-steam binds + reads our serial + creates the Steam Deck + Motion Sensors evdevs — identical to the C PoC. Caught a real portability bug: raw_gadget's no-arg ioctls (RUN/CONFIGURE/EP0_STALL) reject a non-zero `value` with EINVAL, and on musl an omitted ioctl vararg is a garbage register — so they must pass an explicit 0. Opt-in (default off) while the Steam GetControllerInfo feature contract is hardened (to stop the gamepad-evdev churn). Workspace clippy/fmt/test green. Not pushed.
