Wan2.2-S2V-14B Overlay

This is a metadata-only overlay repo for Wan-AI/Wan2.2-S2V-14B.

It contains SGLang pipeline metadata plus vendored official wan/ code. Model weights are still downloaded from the original source repo at runtime and then materialized into a local componentized cache.

Current component classes:

• transformer: WanS2VTransformer3DModel
• scheduler: FlowUniPCMultistepScheduler
• text_encoder: UMT5EncoderModel
• audio_encoder: WanS2VAudioEncoder
• vae: AutoencoderKLWan

The DIT entry in model_index.json is native SGLang (WanS2VTransformer3DModel), not the old WanModel_S2V / WanS2VOfficial* naming.

This overlay also bumps materializer_version so an existing local materialized cache will be rebuilt with the native component names.

Use directly:

sglang generate --model-path MickJ/Wan2.2-S2V-14B-overlay --config configs/wan_s2v.yaml

Or map the official source model ID through SGLANG_DIFFUSION_MODEL_OVERLAY_REGISTRY.
