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.

punktfunk-docs
The punktfunk documentation site: Fumadocs on TanStack Start (Vite + Nitro/bun preset).
Content lives in content/docs/ as .md/.mdx. This site is the source of truth
for the user-facing guides; repo-internal design rationale lives in
../design/.
API reference
/api renders the host's management REST API as an interactive
Scalar reference (linked from the top nav, the docs
sidebar, and the landing page). It reads public/openapi.json — a
snapshot of the repo's generated spec. Refresh it after a management-API change:
# from the repo root — regenerate the spec, then copy the snapshot in:
cargo run -p punktfunk-host -- openapi > api/openapi.json
cp api/openapi.json docs-site/public/openapi.json
