# byte-exact-conformance — cross-architecture byte equality

A crate that compiles WAI's pure-integer decode paths (the rANS entropy coder and the
integer fixed-point syntheses, `#[path]`-included from `wai-rs`) without the system
codec libraries, so the byte-equality matrices (`.github/workflows/wai-byte-equality.yml`,
and *cross-arch byte-equality* in `wai-conformance.yml`) run them on every OS and
architecture. `cargo test --release` here decodes the committed vectors and the
staged-delivery corpus to the goldens in `src/*_golden.rs`, generated once on a
reference machine, and must match them on every machine.

**Provenance.** The goldens are digests of decodes of the vectors under
[`../wai-rs/tests/vectors/`](../wai-rs/tests/vectors/) and of the staged-delivery
corpus; that directory's README states each vector's provenance. Among them, the
`int_video` half-pel clip (`video_real`) is not generated content (see there).
