The arch package job (--features nvenc) tripped the same class of
Codec::PyroWave non-exhaustive matches as windows-host had, in
nvenc_cuda.rs (6 sites) — dispatch-guarded unreachable!() arms, plus
the vk_util-extraction leftover unused imports in vulkan_video.rs.
All Linux host feature combos (none / pyrowave / nvenc,vulkan-encode /
all three) now compile clean on .21.
Presenter: planar_csc.frag (+ committed .spv) — the 3-plane variant of
nv12_csc.frag (separate Cb/Cr R8 planes, same push-constant CSC-row
contract, siting correction self-disables at full-res chroma).
CscPass grows a shared builder + new_planar()/bind_planes_planar()
(GENERAL-layout descriptors — pyrowave planes stay GENERAL); the Vk
presenter builds the planar pass when the device passed the pyrowave
probe, FrameInput::PyroWave rides present_frame (no acquire barrier
needed: the decoder fence-completed and barriered the planes on the
same queue), and run.rs presents it with no demote rung (only device
loss ends the session).

Formatting only, no code change: the signaled-CSC and tvOS commits
(1fcf9e11, 3ba19f28) left six files unformatted and the rust job's
Format step rejects main. cargo fmt --all --check is clean after this.

Clients derive Y'CbCr->RGB from the stream's SIGNALED matrix x range x depth
via shared csc rows (Rust csc_rows + Swift CscRows) instead of hardcoded
709/2020 - a BT.601-signaled stream (a Linux host's RGB-input NVENC) no longer
renders with a constant hue error. Host-side signaling made honest across
NVENC/VAAPI/openh264/GameStream and the session plan's chroma/bit-depth.
Decoded color-bar fixtures (601/709 x limited/full) pin the math in tests on
both cores.
Same presenter, tvOS HDR: tvOS has no Metal EDR API and a bare PQ colorspace
tag composites UNTONE-MAPPED (the "overblown" Apple TV report), so HDR now
splits on the display's live EDR headroom - PQ passthrough when the
per-session AVDisplayManager mode switch landed (a real HDR10 output
tone-maps itself), else an in-shader PQ->SDR tone-map (203-nit reference
white, extended-Reinhard 1000-nit knee, 2020->709) into the proven SDR layer
config. The 10-bit stream keeps its full decode depth either way.

`cargo fmt --all --check` (ci.yml) was red on main: the client re-architecture
commits and origin's windows-shortcut commit landed with rustfmt violations
(e.g. a 104-char .with_context line in hyprland.rs, an unsorted mod block in
vdisplay.rs, the input.rs `{`-placement CI flagged). Reformat the tree so the
fmt gate passes; no functional changes.

The client now advertises VIDEO_CAP_10BIT|HDR and carries the result all
the way to glass:
- csc_rows is bit-depth exact (10-bit limited code points differ from
8-bit by ~half a code) and folds in the P010/X6 MSB-packing factor;
new 10-bit white/black tests.
- The CSC shader grows a params block: mode 0 passes the transfer
through (SDR as-is, or PQ onto an HDR10 swapchain); mode 1 tonemaps
PQ→SDR in-shader (ST.2084 EOTF, 203-nit reference white exposure,
BT.2020→709, soft maxRGB rolloff, sRGB encode) for desktops without
an HDR surface. PUNKTFUNK_TONEMAP_PEAK tunes the rolloff.
- The presenter probes VK_EXT_swapchain_colorspace + an HDR10/ST.2084
10-bit surface format and flips modes in-band with the stream's PQ
signaling: fence-quiesce, then CSC pass + video image (10-bit
A2B10G10R10 intermediate — PQ in 8 bits bands) + overlay pipe +
swapchain rebuild through the deferred-destroy rules.
- P010 decodes through all three paths: Vulkan Video (X6 multiplanar
pool, R10X6 plane views), VAAPI dmabuf (R16/RG1616 plane imports),
software (swscale as before).
- session pump advertises the caps; the host still gates Main10 behind
its PUNKTFUNK_10BIT policy.
Probed on glass hardware: the KDE/NVIDIA surface exposes
A2B10G10R10+HDR10_ST2084, so true PQ passthrough is available there.
Known v1 gaps: software-decode PQ shows untonemapped (8-bit RGBA
carries the transfer baked); the SDR overlay composites unscaled onto
an HDR10 surface (dim OSD); no vkSetHdrMetadataEXT yet.

The §6.1 presenter↔console-UI contract lands: pf-presenter exposes its
device (SharedDevice) and composites at most one premultiplied-alpha
quad per frame (new overlay.frag + LOAD render pass over the swapchain;
zero cost while the overlay returns None). pf-console-ui implements it
with skia-safe on the shared VkDevice: DirectContext via the ash
dispatch chain, a ring of two offscreen render targets (one-frame-in-
flight safe), damage-driven redraws — the OSD re-renders at 1 Hz, the
hint on capture toggles, nothing per-frame. Skia never touches the
swapchain. The session binary carries it behind the default ui feature:
4.9 MB stripped without, 10 MB with (measured).

The decoder's NV12 dmabuf imports per-plane (R8 + GR88, explicit DRM
format modifier, dedicated dup'd-fd import, FOREIGN→graphics acquire)
and a fullscreen-triangle render pass converts it into the presenter's
video image with the CICP-driven coefficients ported from video_gl.rs
(same tests, plus a rows-vs-matrix agreement check). SPIR-V is committed
(shaders/build.sh regenerates) so builds and CI need no toolchain. The
import extension set is probed at device creation; unsupported boxes and
3-failure streaks demote the decoder to software via the existing
force_software contract. The session binary now honors the Settings
decoder preference instead of forcing software.
