Brandon ThomasandClaude Opus 5.5 b05833ef67 h264enc: never crash — no unwrap/expect/unreachable, encode returns Result
- `Encoder::encode` returns `Result` (it was `try_encode(..).expect(..)`, panicking on short
  planes); tests and the example unwrap explicitly.
- P/B macroblock analysis without a reference codes intra instead of `expect`/`unwrap`;
  spatial direct without a list-1 picture predicts zero motion.
- Rate control prior, DPB sliding window, DTS queue, reconstruction buffers, CAVLC writer,
  SAD rows and forward 8x8 transforms without `unwrap`/`expect`; skip-macroblock arms in
  `write_mb` debug-assert instead of `unreachable!`.
- `#![deny(clippy::unwrap_used, …)]` outside tests.

Brandon ThomasandClaude Opus 5.5 7103b58df9 M6.1: filmcraft-h264enc — clean-room H.264 encoder (High/Main/Baseline, CABAC/CAVLC, intra/inter mode decision, deblocking, RC)
- SPS/PPS/AUD/SEI with VUI (SAR, colour description, timing, reorder), avcC, Annex-B or length-prefixed packets
- Intra 16x16/4x4/8x8 + chroma, hexagon ME with half/quarter-sample refinement, 16x16/16x8/8x16/8x8, P_Skip
- B-frames (1-3, spatial direct/B_Skip, L0/L1/Bi), variance AQ, scene-cut IDR
- 4x4/8x8 transforms, deadzone quant, decimation; normative deblocking in the loop
- CABAC (init tables checked against the spec text) and CAVLC
- Rate control: QP, CRF-like, 1-pass ABR + VBV, closed-loop 2-pass VBR
- Slice-parallel encoding with rayon, concurrent B-frames, parallel lookahead/hpel
- ffmpeg-oracle tests: zero decode errors, exact frame counts, decoder output bit-identical to reconstruction
