Steam Deck pass-through (design/steam-deck-passthrough-plan.md), code-complete + all CI checks green on Linux + adversarially reviewed; on-glass validation pending: - usbip/`vhci_hcd` virtual Deck transport (inject/linux/steam_usbip.rs) for non-SteamOS hosts (Bazzite/generic) — presents a real interface-2 USB Deck so Steam Input promotes it. 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.

docs(steam): production plan for Deck client pass-through + shippable usbip host
Write design/steam-deck-passthrough-plan.md — the build plan to ship exact Steam Deck pass-through from the Linux client (incl. the Steam + QAM buttons) plus a virtual Deck on any Linux host. Key validated facts captured so the next session doesn't re-investigate: - Client capture is ALREADY correct: SDL3 maps Steam->Guide, QAM->Misc1; the client forwards BTN_GUIDE/BTN_MISC1; the host maps them to btn::STEAM/btn::QAM. Only precondition: Steam Input disabled on the client (the Decky UX). - Shippable host transport = usbip + vhci_hcd (in-tree + signed everywhere, no module build, no MOK) — PROVEN on Bazzite: Steam promotes the usbip interface-2 Deck (XInput slot + X-Box pad), identical to raw_gadget on SteamOS. - Build steps: refactor steam_gadget.rs into shared Deck-logic + a transport trait; add the usbip transport (vendor-trim the usbip crate to drop rusb/libusb, in-process vhci attach); transport-select raw_gadget->usbip->UHID/DualSense; client leave-shortcut (controller chord + Ctrl+Alt+Shift+D); serial polish. Also checks in the working usbip Deck PoC (packaging/linux/steam-deck-gadget/ usbip-poc/) for the next session to build on. Not pushed.
