GEN3C Local Tests
Local-only parity and smoke tests for the gen3c FastVideo port. The pipeline
smoke test runs without weights; the transformer parity test compares against
the official GEN3C repo and converted weights, and is skipped in CI.

Use only the env-var name for tokens (e.g.,
HF_TOKEN). Never paste a token value.
Shared Environment Setup
Run from the FastVideo repo root in the same env used for FastVideo. See the
add-model-prep skill for canonical clone + install commands.
# Clone the official reference under the FastVideo repo root.
git clone <official_repo_url> GEN3C
uv pip install --no-deps -e ./GEN3C
Do not change core dependency versions (torch, diffusers, transformers,
flash-attn, triton, CUDA packages) without explicit approval.

Review Notes
- Required before handoff: non-skip PASS for each component parity test, including reused components that own weights or numerical behavior.
- Pipeline parity may start as a scaffold; final handoff requires non-skip PASS or an explicit blocker accepted via the escape-hatch process.
