Surface known bf16 numerical alignment bugs by tightening parity bounds:
- DiT parity atol=0.1 -> atol=0.03 (test FAILs at observed diff_max=0.057;
bf16-noise-floor; tracked as OQ-6 root-cause investigation)
- Pipeline parity num_inference_steps=1 -> 4 (test FAILs at video
diff_max=15.10, diff_mean=1.30 = 18.85x compounding ratio vs 1-step
baseline 0.069; pre-existing compounding bug in original magi port,
NOT introduced by Wave 1 -- bisect confirmed; tracked as OQ-6)
- Wan VAE parity atol=5e-2 -> atol=1e-3 (Wan VAE shared fp32 op-order
drift, FV `z * std + mean` vs upstream `z / (1/std) + mean`; affects
all Wan-family pipelines, deferred per OQ-7)
Also split _build_schedulers into _build_fastvideo_schedulers (double-shift,
matching MagiHumanDenoisingStage production) and _build_upstream_schedulers
(single-shift, matching MagiEvaluator.eval_with_text) to faithfully mirror
each side's production scheduler init pattern.
These tests SHIP IN A FAILING STATE intentionally as a forcing function
for follow-up investigation. See OQ-6 + OQ-7 in magi-human.md.
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/.
