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	a41eac933f	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	8b46b821f2	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	3cc8f7dc65	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.

enricobuehler	27271d56d1	feat(steam): raw_gadget virtual Deck — full Steam Input recognition (proven on Deck) ... The interface-2 wall is climbed. packaging/linux/steam-deck-gadget/deck_raw_gadget.c is a raw_gadget userspace emulator of a real 3-interface USB Steam Deck (28DE:1205, mouse=0/keyboard=1/controller=2) on a dummy_hcd loopback UDC, with descriptors captured verbatim from a physical Deck and full HID feature-report handling. Live on a real Deck (SteamOS 3.8.11): hid-steam reads our serial (PFDECK000), creates the Steam Deck + Motion Sensors evdevs, and Steam Input PROMOTES it — controller.txt "Interface: 2 ... device opened ... reserving XInput slot 1" + "input: Microsoft X-Box 360 pad 1". Stable (1 connect, 0 disconnects, no zombie); the kernel Steam Deck evdev is then grabbed by Steam Input which exposes its own X-Box pad, exactly like a real Deck. First time a virtual Deck is fully Steam-Input promoted (UHID can't — it has no USB interface number, so Steam filters it). Also includes the configfs f_hid variant (configfs_gadget_up/down.sh) — the minimal reproducer that proved interface 2 makes Steam open+XInput-reserve the device, but f_hid can't serve feature reports so Steam dropped it as a zombie. Gotchas documented in the README: 7-byte vs 9-byte endpoint descriptor, no-data OUT controls acked via zero-length EP0_READ (not WRITE, else error -110), streamer must not start before SET_CONFIGURATION is acked. SteamOS-host only (needs dummy_hcd + raw_gadget). Recognition proven; feeding real client reports + a host backend is next. Not pushed.
