217-line bespoke loader collapses to a 40-line ANIMA_SPEC in
pipelines/anima/__init__.py (Cosmos converter + llm_adapter sibling +
Cosmos 1.0 forbidden marker).
Drop the class-keyed REGISTRY: Anima and raw Cosmos share
CosmosTransformer3DModel but need different specs. Specs pass via
explicit native_spec= kwarg; make_default_spec(cls) covers the
auto-converter case.
Anima community files bundle the llm_adapter inline alongside the
transformer, so CosmosTransformer3DModel.from_single_file mangles the
118 adapter keys via Cosmos 2.0 substring renames. New helper reads the
safetensors, strips the BFL-style prefix variants, partitions adapter
keys out, runs the rest through diffusers' converter, and loads each
half into its target. SDNQ and layerwise quantization honored; TRT and
GGUF skipped.
