The Skia console UI grows from the single library coverflow into a complete couch shell (Apple gamepad-UI parity), so a Deck/gamescope session is self-sufficient end to end: - Home: host carousel (saved + discovered + Add Host tile) with presence pips, paired locks, wake & connect; A/Y/X/B per the Apple launcher. - In-console SPAKE2 PIN pairing (previously needed the Decky plugin or a desktop), add-host with a controller keyboard, couch settings over the shared Settings store, wake-on-LAN overlay with retry, cancelable dials. - Shell chrome: screen stack with push/pop entrance/exit choreography (slide + fade + recede; aurora↔form backdrop crossfade), per-pad button glyphs (PS shapes vs ABXY, keycaps with no pad), menu haptics, toasts, embedded Geist typography, in-stream start banner. - Steam Deck: our OSK never draws — fields start SDL text input (the new Overlay::text_input_active hook) and Steam's keyboard types; a hint chip points at STEAM + X. Other Linux gets the full gamepad keyboard tray. - punktfunk-session: bare --browse opens Home; --browse host opens that host's library with Home behind it (Decky launches keep working, B now pops instead of quitting). Service threads run discovery, 10 s probes, pairing, wake loops, fetches, and known-hosts persistence. - Presenter contract: Launch actions carry the host, CancelConnect never engages a won race, pad kind/list ride FrameCtx, menu events flow while dialing so B can cancel. Every screen renders to PNG on CPU raster for review (PF_CONSOLE_DUMP=<dir> cargo test -p pf-console-ui -- --ignored dump). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
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 (Ctrl+Alt+Shift+S toggles, --stats forces 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 toggles both the OSD and 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):
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;
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|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).
