Kandinsky-5 Local Tests

Local-only parity tests for the kandinsky5 FastVideo port. Compares the FastVideo Kandinsky-5 transformer against the Diffusers reference (diffusers.Kandinsky5Transformer3DModel); 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. The reference is the published Diffusers class — no clone or upstream install is required beyond the FastVideo diffusers pin.

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.
