Two gaps, both found on the shared Linux/Windows console UI. **The settings tabs only moved for a gamepad.** They were bound to the shoulder buttons and to PgUp/PgDn, and the legend spells PgUp/PgDn out only when NO pad is attached — so with a controller plugged in a keyboard user had nothing to find, and a mouse or a touchscreen could not change section at all. The root cause was wider than the strip: `SkiaOverlay::handle_event` matched only `KeyDown` and `TextInput`, so every mouse button, wheel and touch contact fell past the console into the run loop, which routes pointer input exclusively at `stream.capture` — `None` while you are browsing. Nothing in the console had ever been clickable. Making just the pills answer would not have helped either: the settings screen is opened with X from home, so a mouse could not reach it. So the console gets a real pointer path: - `Overlay::handle_pointer` carries mouse/touch in SWAPCHAIN PIXELS. The run loop converts (it owns the window, hence the display scale, and mouse coordinates are logical while fingers are normalised); the console then hit-tests the very rects it drew last frame. Only DIRECT touch devices are offered — an indirect trackpad already drives the mouse. - Widgets act on the PRESS, not the release. The list and both carousels scroll the focused item toward the centre, so what you pressed has slid out from under your finger by the time it lifts; press-to-act has no such race and there is no drag gesture to compete with. - The hint bar became the pointer's button bar. It is already the console's only on-screen statement of what the face buttons do, and a pointer has none — so its Confirm/Back/Secondary/Tertiary pills are clickable on every screen, which is what puts Settings and Library within reach of a mouse at all. - Tab / Shift+Tab change section; PgUp/PgDn still do, and the keyboard legend now reads "Tab". - Right-click is Back everywhere, EXCEPT at the root: B there quits the launcher and a right-click is far easier to fire by accident. Quitting stays explicit. **Host cards had no menu.** Every other client hangs Wake / Copy link / Edit / Forget off a host card; the console could add a host and connect to one, and that was all — so a renamed machine or a fat-fingered address stayed wrong forever unless you opened a desktop shell. UP on a saved tile now opens that host's menu, the same gesture the Android console uses, on the one direction a horizontal carousel leaves free. - `ConsoleCmd::UpdateHost` edits the stored host IN PLACE. Removing and re-adding would silently drop the fingerprint, the learned MAC, the pinned cards and the profile binding — that is a rename, not a re-pair. - `ConsoleCmd::ForgetHost` drops it; if it is still advertising it returns as a discovered, unpaired row, which is the honest state. - Forget arms on the first press and fires on the second. The other clients forget outright; a console is driven by a thumbstick from across a room. - A pinned profile card offers only Unpin. It is a shortcut, not a second host, and offering to forget the host from it would blur exactly the distinction a pin draws. - "Edit…" REPLACES the menu on the stack rather than stacking over it, so Back from the editor doesn't land on a menu describing the host as it was before the edit. Verified in the pf-lxcheck2 container (this crate compiles to nothing on macOS — a bare `cargo check` there is vacuous): plain build and `clippy --all-targets` clean under `-D warnings`, 72 tests pass. Seven are new, and cover the reported bug directly — a press on a pill selects that tab, and each tab still keeps its own cursor when a pointer is what switched it.
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).
This binary is deliberately dumb: a renderer the front-ends call INTO — the GTK shell
(punktfunk-client), the WinUI shell, and the punktfunk CLI all spawn it through the
same brain (pf_client_core::orchestrate), which resolves policy (profiles, settings,
wake) and hands the result down, normally as a --resolved-spec file. It reads the
shared stores only as the compat fallback for a bare hand-launched invocation.
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), so enrolling on either side makes the other work; this binary never
connects to a host it has no pinned fingerprint for (--fp HEX overrides the store).
Pairing is punktfunk pair <host> — the CLI, which ships alongside this binary in every
package and needs no window and no toolkit either. punktfunk-session --pair still works
for one release (someone's provisioning script calls it today) but prints a deprecation
notice: pairing is a trust ceremony and belongs to the brain, not a renderer.
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 is vendor-ordered: Vulkan Video → VAAPI →
software on Linux, Vulkan Video → D3D11VA → software on Windows, with VAAPI/D3D11VA first
on Intel — every rung native since M10; see "Decode rungs" below): the Vulkan 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 the Vulkan and VAAPI/D3D11VA paths (the CPU rung is 8-bit by contract and refuses
10-bit rather than mis-scaling it), 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.
Decode rungs (M10: native only)
This binary contains no FFmpeg. auto walks native rungs — pf-vkdecode over Vulkan
Video, then the platform's own (pf-dxvadec on Windows, pf-vaadec on Linux), then the CPU
rung (openh264/rav1d). The libavcodec rungs that used to sit under each of them are
deleted, along with pf-ffvk and the ffmpeg-next dependency.
Two of the native rungs have never decoded a frame on real hardware (native VAAPI at all; native D3D11VA's AV1 leg). They run anyway — with the libavcodec twins gone, the only thing below them is the CPU, so barring them would cost the session hardware decode outright rather than move it one rung down. What replaces the safety net is the log: every session names the rung it landed on with its evidence state,
decode rung active rung=native-vulkan codec=HEVC hardware_verified=true evidence=...
…and that line is a WARNING when nothing has ever decoded a frame through the
rung/codec pair the session chose. pf-client-core's video.rs module docs carry the full
table; read any field report about M10 against it.
Debug/bisect knobs: PUNKTFUNK_DECODER=native-vulkan|native-vaapi|native-d3d11va|software
(a pin skips the vendor order, which is how a lab run reaches a rung auto will not pick
on this device; a pinned rung that cannot open still falls through to the standard ladder,
loudly; native-vaapi also takes PUNKTFUNK_VAAPI_DEVICE=/dev/dri/renderDNNN to choose
the GPU). The pre-M10 spellings vulkan/vaapi/d3d11va named the libavcodec rungs
specifically; they are MIGRATED onto the native rung for the same hardware family, with a
warn line saying so — every desktop Settings UI offered those values, so refusing them
would end a session over a dropdown someone picked long ago.
PUNKTFUNK_PRESENT_MODE= mailbox|fifo|immediate|fifo_relaxed (default MAILBOX, FIFO where the surface offers no
MAILBOX — AMD on Windows), 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).
PUNKTFUNK_AU_FAULT=drop|truncate|flip[:period] deliberately corrupts decoder input on the
native Vulkan lane (default period 60 — one AU a second at 60 fps; inert everywhere else, and
inert entirely if the value doesn't parse). drop swallows the AU, so the next one references a
picture that was never decoded — the bitstream planner catches it immediately. truncate delivers
a picture whose slice data stops mid-frame and flip alters one byte deep in the payload: both
parse perfectly, so only the driver's per-frame decode-status query can see them, and neither is
visible at all on a driver without queryResultStatusSupport. Watch the
result on the Detailed stats line's integrity: term (damaged = concealment the planner caught,
refused = AUs the decoder rejected outright, driver-failed = the hardware's own verdict, run
= consecutive frames with no picture, worst run = the longest such stretch of the session — the
once-a-second run sample misses the bad moment almost every time — and no driver status = this
device cannot answer the driver question at all). A session that lands on any other lane says so
in the log rather than faulting silently.
Note that PUNKTFUNK_AU_DUMP records the AU as it arrived from the HOST, while the fault injector
runs later, at the native decoder's own entry. On a faulted run the dump is therefore the clean
bitstream — reconstruct the damaged bytes from the spec if you need them (the injector is pure and
deterministic).
