Two maintenance pieces, both salvaged from the stale-branch cleanup: - .github/workflows/wai-byte-equality.yml — the one genuinely-unlanded artifact stranded on harness-econ: a 5-arch matrix (linux x86_64/aarch64, macos arm64/x86_64, windows x86_64) that decodes WAI fixtures and asserts byte-identical golden output — the `replicate` determinism contract checked on real silicon. main had wai-conformance + wai-neural-e2e but no cross-architecture byte-equality job. Dropped the stale rans.rs path trigger (that source was merged away); the tested crate (wai-byte-exact-conformance) and the remaining neural sources are current. - tools/branch-drift-audit.sh — surfaces branch drift BEFORE it rots: per branch, ahead/behind main, unpushed, and patch-stranded count with a verdict (absorbed → delete vs LAND → cherry-pick forward). The fix for the "long-lived branches drift past clean-merge and strand work" failure this cleanup addressed. Co-Authored-By: Claude Opus 4.8 <[email protected]>

# The `replicate` determinism contract, checked on real silicon. WAI claims its
|
|
# integer-exact decode paths (rANS entropy coder, integer fixed-point synthesis)
|
|
# produce BYTE-IDENTICAL output on every machine. This matrix proves it: five
|
|
# OS/arch combinations decode the same fixtures and assert the same golden
|
|
# bytes — rANS streams produced by CompressAI's upstream encoder, and an
|
|
# int_synth output hash produced on the reference machine (macOS arm64). One
|
|
# diverging byte anywhere fails the suite.
|
|
#
|
|
# The conformance crate (`wai/byte-exact-conformance`) #[path]-includes the
|
|
# pure-integer sources from wai-rs — no system codec libraries, no ONNX runtime
|
|
# — so every leg runs in about a minute.
