Transaction Science 17a8764fe9 determinism-tiers §6: what runs on Windows x86_64 now, and what does not
§6 (dated 2026-09-27) said there was no Windows leg. Two are back: the golden-byte suite in
wai-byte-equality.yml's windows-x86_64 leg since 5f1158154 (2026-11-05), and the cargo-class
job of wai-conformance.yml since 6ca202b8a (2026-11-10). The section now names a passing run
of each, read from the forge on 2026-11-10: run 28636 (job 115713), where every golden of the
suite passed on Windows, and run 28810 (job 116278), the cargo-class leg. It says what does
not run there: the conformance workflow's own byte-equality job keeps its unix legs, its other
jobs have no Windows leg, and within the cargo-class job the steps that need a unix shell or
tool (the JPEG AI math-library symbol check, each integer feature alone, the wasm32 builds,
the audio provenance check, the OER C kernel) are skipped there. No macOS x86_64 or Windows
arm64 leg.

The rows that said Windows had not decoded something now name the run where it has: the
integer video and keyframe goldens, the int_codec audio and splat goldens and int_mlicpp's
golden (run 28636), and float_repro's pinned-bits tests and tests/int_mlicpp.rs in both
profiles (run 28810, where the host-exp comparison reports itself ignored, as its gate says
it does on Windows).

### What the determinism tiers' evidence runs on Windows
- **`extensions/determinism-tiers.md` §6** no longer says there is no Windows leg. Windows x86_64
runs the golden-byte suite in `wai-byte-equality.yml`, back since 2026-11-05, and the cargo-class
job of `wai-conformance.yml`, back since 2026-11-10; the section names a passing run of each, and
what does not run there: the conformance workflow's own byte-equality job and its other jobs,
and the cargo-class steps that need a unix shell or tool. The rows on the golden-byte suite,
`float_repro`, `int_mlicpp` and the integer codecs name their Windows runs.
