The FLUX and SDXL loaders know their architecture's block names up front, which
does not scale across ComfyUI's ~99 model configs. The new Universal node
discovers a model's block layout at runtime instead: stack names, stack sizes
and their execution order all come from the loaded model, so pruned, distilled
and brand-new architectures work without a code change.
Concatenating the discovered stacks puts every block on one normalised depth
axis, split into five buckets, alongside embeddings, output head and text
encoder. Covers SD1.5/2/3, SDXL, FLUX, Chroma, AuraFlow, PixArt, HiDream,
Qwen-Image, Wan, LTX-Video, Mochi, HunyuanVideo/DiT, Lumina and Cosmos.
Verified against real ComfyUI: models built from ComfyUI's own configs on the
meta device plus its *_to_diffusers key tables, 8000+ authentic state-dict keys
across 11 architectures, none falling through to "Other Tensors". That pass
found and fixed real gaps: SD3's negative "joint_blocks.-1" index, Lumina's
noise_refiner/context_refiner stacks, AuraFlow's native double_layers naming,
several conditioning embedders, and FLUX's ControlNet pos_embed_input.
No widget was added, removed or reordered on the FLUX or SDXL nodes, so
existing workflows are unaffected.
Bumps version to 1.2.0.
