## [Unreleased]

Staged workspace version: `0.9.1`.

- Refactors the CPU JPEG AVX2 and NEON paths around unforgeable capability
tokens and safe kernel entry points. SIMD dispatch, IDCT/color arithmetic,
tests, and benchmark wrappers no longer require unsafe calls; the remaining
raw loads/stores and exact-AVX2 bridge are isolated behind fixed-size safe
interfaces. Ten production SIMD unsafe blocks remain, with no `unsafe fn`,
under an AST-enforced 24-block cap.
- Uses `fearless_simd 0.7.0` for AArch64 NEON kernels while preserving the
existing AVX2-only x86 acceleration envelope with a private exact-AVX2 token;
`fearless_simd::Avx2` is intentionally not used because its 0.7 contract is
the broader x86-64-v3 feature set.
- Adds deterministic CPU JPEG decode and expanded SIMD microbenchmarks covering
grayscale, 4:4:4, 4:2:2, full/odd/cropped 4:2:0, row streaming, specialized
IDCT, tail widths, and unaligned source rows.

## [0.9.0] - 2026-08-10

- Breaking: all expert Metal APIs in `j2k-metal-support`, `j2k-metal`,
