enricobuehler	ef39050dbc	docs: repo-wide housekeeping — sync README & docs with the code as shipped ... Six parallel audits swept the root docs, docs-site, every per-directory README, and the packaging docs; every claim below was verified against the source before editing. - README: Layout gains the six missing crates (pf-client-core, pf-presenter, pf-console-ui, pf-ffvk, pf-driver-proto, punktfunk-tray), clients/session, api/ and ci/; Linux/Windows client rows reflect the shell + Vulkan-session split and the Vulkan Video -> VAAPI/D3D11VA -> software decode chains; the "every client over a C ABI" claim is corrected (Rust clients link the core directly); tiered stats overlay + console shell noted; Apple row mentions AV1. - CONTRIBUTING: drop the dead CLAUDE.md link (deliberately untracked); point at the README's build/invariants sections. SECURITY: 0.9.0. - host-cli/pairing: --allow-pairing/--require-pairing are no-op legacy names — pairing is required by default, --allow-tofu is the real flag; document --data-port and --idle-timeout-ms. - configuration: document PUNKTFUNK_RECOVER_SESSION_CMD (session-crash recovery hook), PUNKTFUNK_MDNS, PUNKTFUNK_DATA_PORT. - virtual-displays/gnome: GNOME per-client scaling shipped (host- persisted) — flip the ❌ to ✅ and describe how it works. - stats: new "Detail levels" section (Off/Compact/Normal/Detailed + per-platform cycle gestures); retire the GTK hand-off note. - clients/install-client/status/roadmap: decode chains, Windows client validation narrowed to HDR-only pending, adaptive bitrate, console shell, Apple AV1, Windows host vendor list. - Sub-READMEs: clients/linux rewritten for the re-architecture; session Windows decode rung + d3d11va knob; Windows tiered overlay; Android minSdk 28; decky file table; host zerocopy/ path; scripts port 47992 and steamos-host.md; pf-dualsense source path. - packaging: canary version bases are tag-derived (<next-minor> via pf-version.sh/.ps1), codecs-extra not ffmpeg-full, document the pinned offline-Skia tarball + SKIA_BINARIES_URL and vulkan-headers. - Convert 15 dangling design/*.md links to the punktfunk-planning prose convention (those docs live in the private planning repo).

enricobuehler	796d381926	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	8b47be668f	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	6bbe7ae137	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	6e41356919	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	b2acebdf58	chore(windows): clean up build/packaging - drop vendored driver binaries + the LLVM-21 pin ... Now that the drivers build from source in CI, remove the dead checked-in binaries and the toolchain cruft they left behind: - Delete packaging/windows/{pf-vdisplay,gamepad-drivers}/ (the prebuilt .dll/.inf/.cat/.cer). pack-host-installer.ps1 builds + signs all three drivers from the drivers/ workspace and nothing reads the vendored dirs anymore; stage-pf-vdisplay.ps1's -VendorDir is now a mandatory build-output path, not a vendored default. - Drop the LLVM-21 pin. The vendored bindgen 0.71->0.72 bump (the shipping pack already builds green on the runner-default clang 22) retired the bindgen-0.71 layout-test overflow that needed LLVM 21.1.2, so windows-drivers.yml + provision-windows-wdk.ps1 no longer install/point at C:\llvm-21 (~898 MB off a fresh provision) - both driver builds now use one toolchain (clang 22 + bindgen 0.72). - pack -SkipBuild on the gamepad build (build-pf-vdisplay.ps1 already builds the whole workspace), build-web.ps1 reaps a stale node too, deploy-dev.ps1 nefconc path + comments. - Reword the vendored-driver references (build scripts, .iss, READMEs, the vite web-bundle comment) to the build-from-source reality.

enricobuehler	8d5e33da0f	fix(windows-installer): build the gamepad drivers from source in CI too ... Fold the pf-dualsense (DualSense / DualShock 4) and pf-xusb (Xbox 360 / XInput) UMDF drivers into the in-tree drivers workspace (their source had stale ../../crates/wdk-* path-deps from before the wdk vendoring reorg and could no longer build at all) and build them from source per release, exactly like pf-vdisplay - same anti-stale reasoning. One `cargo build --release` now builds all three drivers against the vendored wdk-sys (incl. the bindgen 0.72 pin), and build-gamepad-drivers.ps1 signs pf_dualsense + pf_xusb (clear FORCE_INTEGRITY -> sign dll -> stampinf -> Inf2Cat -> sign cat) with one shared cert + .cer, matching the layout install-gamepad-drivers.ps1 expects. pack-host-installer.ps1 builds + stages them instead of the retired checked-in binaries. Validated on the runner: the whole workspace (pf-vdisplay + pf-dualsense + pf-xusb) builds with CARGO_TARGET_DIR=C:\t set, and build-gamepad-drivers.ps1 produces signed pf_dualsense.{dll,inf,cat} + pf_xusb.{dll,inf,cat} + the .cer.
