Phases 4+5 of design/pyrowave-444-hdr.md. The Metal decoder needs NO new ABI: every frame's sequence header carries chroma (444) and, since the Phase-3 stamps, the PQ/BT.2020 bits — so the decoder self-configures per session. Decoder: WaveletLayout grows the 4:4:4 block space (chroma runs the full pyramid like luma — no level-0 skip, no early half-res emit; the Metal kernels were already chroma-agnostic, only the dispatch structure changes); the parser accepts chroma_resolution=444, reads the PQ transfer bit, and lifts the even-dims rule for 444; the plane ring allocates full-res chroma and r16Unorm for PQ streams; CSC rows switch to depth-10 MSB-packed. Presenter: planar HDR passthrough reuses pf_frag_planar on an rgba16Float drawable (itur_2100_PQ + EDR metadata interpret the samples — same split as pf_frag/pf_frag_hdr), plus a new pf_frag_planar_tm PQ->SDR tone-map (shared pqToSdr tail refactored out of pf_frag_hdr_tv) for tvOS-without-headroom AND macOS WINDOWED sessions, whose IOSurface present path (the DCP-panic mitigation) is BGRA8-only. SessionModel stops stripping the HDR/10-bit/444 caps on the PyroWave opt-in. New golden: au-dense444 + upstream's own 4:4:4 reference planes (regenerated via the extended pyrowave_dump_golden); Metal decode matches at 64-67 dB (420 fixtures re-verify 77-88 dB). Full Apple suite 157 tests green on a real M-series GPU. Docs updated: the 8-bit-SDR-only wording is gone, the Windows host is no longer 'on the roadmap', bpp scaling documented.

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; design rationale lives in the internal punktfunk-planning repo.
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
