UX polish batch 2 (plan workstreams D/E5/E6): - D: a mouse/keyboard game library page over pf-client-core::library (the GTK ui_library.rs counterpart): responsive 2-6 column poster grid (2:3 portraits, store badge, monogram placeholder while art streams in), loading / error+retry / empty / grid states, tap-to-play via a normal spawn carrying --launch id. Poster bytes land in a disk cache (%LOCALAPPDATA%\punktfunk\art-cache) so the Image widget loads file:/// URIs (reactor has no from-bytes source) and revisits render instantly. Reached from a paired host's "Browse library..." menu item behind the new "Show game library (experimental)" Settings toggle (the shared library_enabled field, Apple/GTK parity). A Shared::library_gen generation guard keeps a superseded fetch from publishing (speed-test pattern). - E5: the session window opens at the shell's own top-left (--window-pos, new SessionOpts::window_pos) instead of centered on the primary display - streams land on the monitor the shell is on, and the hide/restore handoff reads as one window changing content. Fullscreen follows that display. - E6: the Help shortcuts add Alt+Enter and the controller escape chord (LB+RB+Start+Back, hold to disconnect). Also: rustfmt normalization of the merged probe helper.

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).
