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).

# punktfunk-session
|
|
|
|
The Vulkan session binary: one stream per invocation in an SDL3 window — no UI toolkit,
|
|
no widgets, terminal stats. The power-user / gamescope stream client, and the stage-2
|
|
presenter of the Linux client re-architecture (punktfunk-planning:
|
|
`linux-client-rearchitecture.md`).
|
|
|
|
```
|
|
punktfunk-session --connect host[:port] [--fp HEX] [--launch id] [--fullscreen] [--stats]
|
|
punktfunk-session --browse host[:port] [--mgmt PORT] [--fullscreen]
|
|
```
|
|
|
|
`--browse` opens the console game library (the Skia coverflow over the animated aurora)
|
|
instead of connecting: A launches the focused title as a stream in the same window,
|
|
session end returns to the library, B quits (Gaming Mode returns). Paired hosts only —
|
|
pairing is the desktop client / Decky plugin's job. `PUNKTFUNK_FAKE_LIBRARY=<file.json>`
|
|
feeds canned entries with no host (portrait paths starting with `/` load from disk).
|
|
|
|
Reads the same identity / known-hosts / settings stores as the desktop client
|
|
(`punktfunk-client`) — pair there (or via its headless `--pair`) first; this binary never
|
|
connects to a host it has no pinned fingerprint for (`--fp HEX` overrides the store).
|
|
|
|
Stdout is the machine interface: `{"ready":true}` after the first presented frame,
|
|
`stats: …` once per second while the overlay tier isn't Off (always the full detailed
|
|
text, whatever the OSD shows; `--stats` forces the overlay on), one
|
|
`{"error"|"ended": …}` JSON line on the way out. Logs go to stderr. Exit codes: `0`
|
|
clean end, `2` connect failed, `3` trust rejected / pairing required, `4` presenter
|
|
init failed.
|
|
|
|
In-stream keys match the desktop client: click captures input (Ctrl+Alt+Shift+Q
|
|
releases), Ctrl+Alt+Shift+D disconnects, F11 toggles fullscreen; the controller escape
|
|
chord (L1+R1+Start+Select, hold to disconnect) works the same.
|
|
|
|
The default build carries the Skia console UI (`ui` feature): the stats OSD and capture
|
|
hint render in-window. Ctrl+Alt+Shift+S cycles the OSD tier live — Off → Compact (one
|
|
line: fps · latency · Mb/s) → Normal (mode + end-to-end percentiles) → Detailed (decoder
|
|
path + per-stage latency equation); any tier but Off also emits the stdout mirror.
|
|
`--no-default-features` is the ~5 MB power-user build — same streaming, stats on stdout
|
|
only, no Skia anywhere in the dependency tree.
|
|
|
|
Decode follows the Settings preference (auto: Vulkan Video → VAAPI → software on Linux,
|
|
Vulkan Video → D3D11VA → software on Windows): FFmpeg's Vulkan Video decoder runs on the
|
|
presenter's own device where the stack supports it (every vendor, zero copy); VAAPI
|
|
dmabufs import per-plane elsewhere (D3D11VA textures on Windows); software is the
|
|
universal fallback. 10-bit Main10 and HDR10 are advertised
|
|
(`VIDEO_CAP_10BIT|HDR`): P010 decodes through all three paths, and PQ streams present
|
|
on an HDR10/ST.2084 swapchain when the desktop offers one (KDE HDR, gamescope) or
|
|
tone-map in-shader to SDR when it doesn't (`PUNKTFUNK_TONEMAP_PEAK` tunes the rolloff,
|
|
default ≈1000 nits). The host still gates the upgrade behind its `PUNKTFUNK_10BIT`
|
|
policy.
|
|
|
|
Debug/bisect knobs: `PUNKTFUNK_DECODER=vulkan|vaapi|d3d11va|software`, `PUNKTFUNK_PRESENT_MODE=
|
|
mailbox|immediate` (default FIFO), `PUNKTFUNK_VK_DEVICE=<index>` (multi-GPU), and
|
|
`PUNKTFUNK_HW_FAULT=import` (fault every VAAPI dmabuf import — proves the three-strike
|
|
demotion to software on healthy hardware).
