Phase 0 of design/pyrowave-codec-plan.md — the opt-in wired-LAN ultra-low- latency codec. Vendored at upstream 509e4f88 (API 0.4.0, Granite 44362775, volk + vulkan-headers pins in PUNKTFUNK-VENDOR.txt), pruned to the 6.6 MB the standalone no-renderer build needs; scripts/vendor-pyrowave.sh reproduces the tree (a pin bump is protocol-affecting, plan §4.2). build.rs drives the wrapper CMakeLists (static archives incl. a static C-API lib upstream only ships shared) + bindgen over pyrowave.h; Linux and Windows only, empty stub elsewhere (Apple gets a native Metal port, §4.7). Offline-safe by construction: no network, no system lib, vendored Vulkan headers — same model as the opus dep (flatpak builder has no network). Phase-0 validation on .21 (RTX 5070 Ti, driver 610.43.03): - upstream pyrowave-c-test + interop test (incl. dmabuf/DRM-modifier Vulkan<->Vulkan) pass, from the pristine AND the pruned tree - GPU kernel times at ~1.6 bpp noise: encode/decode 0.090/0.042 ms @800p, 0.146/0.067 @1080p, 0.226/0.103 @1440p, 0.477/0.201 @4K — order of magnitude under NVENC's 1-2 ms retrieve, CBR lands within ~100 B of target - cargo test -p pyrowave-sys green (static link + API-version pin check) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
