Pressing guide/Steam/QAM collided with the client device's own shell: iOS 26 opens its Game Overlay for the Home press (no app opt-out until iOS 27 makes it a user setting), and a Gaming-Mode client opened BOTH Steam overlays for one press — the local one covering the stream. Two cross-client tier-P settings, zero wire changes: - system_buttons (auto|forward|local): raw guide+misc1 passthrough. Auto forwards everywhere EXCEPT under gamescope, where SteamOS reacts to the same physical press no matter what. - guide_gesture (auto|on|off): hold Select ALONE ~350ms sends the HOST's guide, down until release — held on, that's the host's long-press, which opens a Gaming-Mode host's QAM for regular pads. A Select tap is delivered on release with its up TAP_PRESS (50ms) behind, because per-transition sends fold into seq'd GamepadState snapshots and a back-to-back pair can coalesce into no press at all. A Select inside a combo (the escape chord) passes through untouched. Auto arms it only where the raw press can't reach the host cleanly: gamescope, iOS/iPadOS, tvOS. The same SelectGesture rules live in pf-client-core (pure state machine + unit tests), the Apple client (mask-diff adaptation in GamepadCapture), and Android's GamepadRouter. Settings rows on every surface (GTK, WinUI, console UI, Decky, Apple x2, Android x2) with profile plumbing throughout. punktfunk-session grows a control socket ($XDG_RUNTIME_DIR[/app/$FLATPAK_ID]/punktfunk-session-ctl.sock — the one runtime path a flatpak and the host see identically): 'guide'/'qam' verbs inject synthetic taps. The Decky panel gains a Host menus section (visible while the client runs) whose buttons press the host's Steam/QAM and close the local menu so the host's shows through. iOS 27's GCControllerHomeButtonSettingsManager deep-link is a TODO (the class needs the Xcode 27 SDK to compile). Docs: input, client-settings, steam-deck. Design: punktfunk-planning design/system-buttons-routing.md. Gates: docker clippy --all-targets --locked -D warnings + tests (pf-client-core 88 incl. 6 new gesture tests, pf-console-ui 47), cargo fmt --all --check, swift build (macOS), gradle kit+app compile, decky tsc --noEmit + py_compile. clients/windows not compiled (no box).
punktfunk-docs
The Punktfunk documentation site: Fumadocs on TanStack Start (Vite + Nitro/bun preset).
Content lives in content/docs/ as .md/.mdx. This site is the source of truth
for the user-facing guides; design rationale lives in the internal punktfunk-planning repo.
API reference
/api renders the host's management REST API as an interactive
Scalar reference (linked from the top nav, the docs
sidebar, and the landing page). It reads public/openapi.json — a
snapshot of the repo's generated spec. Refresh it after a management-API change:
# from the repo root — regenerate the spec, then copy the snapshot in:
cargo run -p punktfunk-host -- openapi > api/openapi.json
cp api/openapi.json docs-site/public/openapi.json
Nothing in CI diffs the two, so the snapshot goes stale silently — that manual cp is the only
thing keeping them in sync. Before publishing docs, check that they match:
diff <(jq -S . api/openapi.json) <(jq -S . docs-site/public/openapi.json)
That should print nothing. Right now it doesn't: the committed snapshot predates the
/api/v1/update/check, /api/v1/update/apply and /api/v1/update/status endpoints, so the
published /api reference is missing the host self-update surface — re-copy it.
Develop
bun install
bun run dev # http://localhost:3001 (docs at /docs)
CI gates every change on bun run build followed by bun run lint (the TypeScript typecheck), in
that order — the build emits the .source typegen the typecheck imports. Run both before you push.
Build & serve
bun run build
bun run start # serves .output/ via Bun
