enricobuehler	5c7e0afa99	fix(host): Linux virtual-pad feedback access — hidraw udev rules, per-pad DS MAC, SET_REPORT acks ... Root-cause fixes for "rumble + adaptive triggers never work with Linux hosts" (the capture code itself was proven good on-hardware — see the new tests): * 60-punktfunk.rules now grants the `input` group the VIRTUAL pads' hidraw nodes (DS/Edge/DS4/Switch/Deck/SC). Steam/SDL drive DualSense adaptive triggers, lightbar, and player LEDs exclusively over hidraw — and Steam without hidraw demotes a PlayStation pad to a generic evdev device, losing its rumble handling too. Coverage no longer depends on the distro's steam-devices rules + logind's active-seat uaccess ACL (which a headless/ dedicated streaming session never gets). Verified live: nodes now come up root:input 0660. * Per-pad MAC in the DualSense (0x09) and DS4 (0x12) pairing feature replies: hid-playstation adopts the MAC as the HID uniq and SDL/Steam dedup controllers by that serial — identical MACs made a second virtual pad read as the first one re-connecting over another transport. * DualSense/DS4 UHID backends now ack UHID_SET_REPORT (err=0) instead of ignoring it, so a SET_REPORT writer no longer blocks on the kernel's 5 s timeout. * New #[ignore] on-box tests play the GAME's role against a real kernel and pin the full feedback surface (all green on real hw): DualSense evdev-FF + raw hidraw output report (rumble/lightbar/LEDs/both trigger blocks verbatim, per-pad uniq), uinput X-Box FF upload→pump→stop-on-erase, and usbip Deck 0xEB rumble via the controller interface (idle interfaces ACK silently, like real hardware). Windows note: the UMDF driver keeps its own pairing blob copies — the shared- MAC dedup hazard exists there too and needs a driver-side follow-up.

enricobuehler	b8fd652cb8	fix(packaging): autoload vhci-hcd and open its attach files for the usbip Deck pad ... Steam Input only adopts the virtual Steam Deck controller when it arrives as a real USB device (raw_gadget or usbip/vhci transports); the UHID fallback has no USB interface and Steam ignores it. On a stock host neither precondition for usbip held: vhci-hcd isn't loaded, and its sysfs attach/detach files are root-only while the host runs as a user service — so every session silently fell back to UHID and 'no controller appears on the host' (live-debugged 2026-07-08: client events all arrived, the pad existed, Steam just refused it). Ship both preconditions with the host packages: * modules-load.d/punktfunk.conf loads vhci-hcd at boot (rpm/deb/arch; Bazzite gets it via the RPM payload + a modprobe in the sysext post-merge hook) * a udev rule in 60-punktfunk.rules grants the input group write on vhci_hcd's attach/detach whenever the device appears Verified end-to-end on a live host: usbip in-process attach, hid-steam binds all three interfaces, 'Steam Deck' + motion evdev appear, and Steam adopts the pad (client-mode grab + its own virtual X360 emission).

enricobuehler	64f664476b	feat(host): virtual DualSense via UHID (hid-playstation) — device + report mapping ... Roadmap #5 (rich DualSense). A UHID device presents a real Sony DualSense to the kernel's hid-playstation driver (matched by VID 054C/PID 0CE6), which exposes the full controller — gamepad, motion sensors, touchpad, lightbar/player LEDs, adaptive triggers — unlike the uinput X-Box-360 pad. - inject/dualsense.rs: hand-rolled /dev/uhid codec (no bindgen) mirroring the uinput style; the canonical inputtino 232-byte USB HID report descriptor + the feature-report replies (calibration 0x05 / pairing 0x09 / firmware 0x20) — answering hid-playstation's GET_REPORTs during init is REQUIRED or it creates no input devices. DsState::from_gamepad maps a GameStream/XInput frame → the DualSense input report (buttons/sticks/triggers/dpad, + touchpad/motion fields); service() answers GET_REPORTs and parses HID OUTPUT (rumble / lightbar RGB / player LEDs / adaptive triggers) into quic::HidOutput. - scripts/60-punktfunk.rules: grant /dev/uhid to the 'input' group (like /dev/uinput). - `punktfunk-host dualsense-test`: standalone validation (no streaming session). Validated live: `dualsense-test` → hid-playstation binds + loads ff_memless + led_class_ multicolor; the kernel creates "Punktfunk DualSense 0" (event/js gamepad + Motion Sensors + Touchpad + Headset Jack) at VID 054c/PID 0ce6, plus the lightbar at /sys/class/leds/ input*:rgb:indicator; js shows the Cross button firing + the left-stick sweep. Clippy/fmt clean, workspace tests green. Wiring into the session (pad-type select, touchpad/motion routing, HID-output back-channel) is the next commit.

enricobuehler	8cceb93541	rename: lumen → punktfunk, everywhere ... Full project rename, decided 2026-06-10: - Crates/binaries: punktfunk-core / punktfunk-host / punktfunk-client-rs. - C ABI: punktfunk_* symbols, Punktfunk* types, include/punktfunk_core.h, PUNKTFUNK_FEATURE_QUIC guard (header regenerated; cbindgen renames updated, incl. PUNKTFUNK_BTN_*/PUNKTFUNK_AXIS_* wire constants). - Protocol: punktfunk/1 — control-plane magic LMN1 → PKF1, nonce salt lmn1 → pkf1. WIRE BREAK: clients must be rebuilt from this revision. - Env knobs: PUNKTFUNK_VIDEO_SOURCE / PUNKTFUNK_COMPOSITOR / PUNKTFUNK_ZEROCOPY / …. - Host config dir: ~/.config/punktfunk (the box's dir was migrated in place — the persistent identity is unchanged, pinned fingerprints stay valid). - Swift package: PunktfunkKit + PunktfunkCore.xcframework + PunktfunkConnection (Sources/PunktfunkClient app + tests renamed with it); build-xcframework.sh updated. - scripts/: 60-punktfunk.rules, punktfunk-host.service; OpenAPI doc regenerated. Also: scripts/headless/run-headless-kde.sh — full headless Plasma bringup. Root cause of "desktop but no apps/settings" over the stream: plasmashell launched without XDG_MENU_PREFIX=plasma-, so the launcher resolved a nonexistent applications.menu and rendered an empty menu. The script sets the complete KDE session env (menu prefix, KDE_FULL_SESSION, session version) and rebuilds ksycoca before starting plasmashell. Gate: 97/97 tests, clippy -D warnings (both feature sets), fmt, C-ABI harness PASS, zero lumen references left outside .git.
