Document Wave 7 CFG + negative-prompt investigation findings in the
numerical-alignment investigation section. Key results: CFG math is
identical on both sides; audio VAE is bit-exact vs official (new parity
test confirms); root cause of production audio drift was the incomplete
negative prompt in FV's preset (missing audio-quality + speech-delivery
blocks from upstream video_generate.py:222-224).
Update Phase 11 status table with the new SA-official parity test row
(PASS, diff_max=0, diff_mean=0). Add test_magi_human_sa_audio_official_parity.py
to the running-tests command block and the What-each-test-covers section.
Mark OQ-6 as PARTIALLY-RESOLVED: production neg-prompt fix shipped in
this wave; parity-test 4-step compounding is a separate inherent
FlowUniPC scheduler phenomenon, not a code bug. Update Last-verified
to 2026-05-01 (Wave 7).
tests/local_tests/ holds local-only parity, smoke, and component tests
organized by model family (e.g. tests/local_tests/ltx2/,
tests/local_tests/stable_audio/). They typically require a checked-out
reference repo and/or model weights and are skipped in CI; see each family's
README.md for setup. The top-level
tests/local_tests/README.md is the family index.
The CI-backed test suite still lives in fastvideo/tests/.
