## Summary Tighten `hdr-regression` Window F `maxFrameFailures` from 5 → 0 now that Chunk 4 (matrix3d support + scene initial-state) has landed. ## Why Window F (transform + scale + border-radius on the video itself) was the remaining known-fail in the `hdr-regression` suite, baked into the golden so the suite stayed green while Chunk 4 was outstanding. After Chunk 4 fixed `parseTransformMatrix` (matrix3d support) and the shader-transitions initial-state, re-running the suite shows **0 failed frames** against the existing golden — the encoder is byte-deterministic, and Window F's GSAP rotation/scale happens to emit 2D `matrix()` rather than `matrix3d()`, so the same golden is still correct after the fix. Tightening the budget catches any drift in the layered HDR compositor immediately. ## What changed - `tests/hdr-regression/meta.json`: `maxFrameFailures` 5 → 0 (matches `hdr-hlg-regression`). - `tests/hdr-regression/README.md`: Window F row + Fix history section updated to reflect the new state. ## Test plan - [x] `bun run test --filter hdr-regression` — passes with 0 failed frames at the new budget. ## Stack Follow-up to Chunk 4 (transform & clipping). Reviewable separately so the budget tightening is decoupled from the code fix.

"description": "Comprehensive HDR10 (BT.2020 PQ) regression suite. Eight back-to-back 'windows' (A–H) lock down the layered HDR compositing pipeline against the most common composition shapes: baseline pass-through, wrapper-vs-direct opacity, z-order sandwiches, side-by-side multi-source, transform + border-radius, object-fit letterbox, and a shader transition between an HDR video and an HDR PQ image. Window C (direct <video> opacity) is fixed by Chunk 1. Window F (transform + border-radius) is fixed by Chunk 4. The golden is byte-deterministic and `maxFrameFailures` is 0 — any drift in the layered HDR compositor is caught immediately.",
