README captures: reference assets, weight-dir layout, run commands,
per-component status, and live blockers (lm_head allowlist, scheduler
config-flag pin requirement, tokenizer `text_len` reconciliation).
PORT_STATUS captures: component matrix, parity commands + last result,
open questions (pin Z-Image clone SHA, pin HF id), issues I001-I005
(lm_head allowlist resolved, scheduler-config pin still open, transformer
+ pipeline NOT_STARTED), and the bf16 / scheduler-config-widening
decisions made in this PR.
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/.
