Track exact stock-loader calls across equal strengths, disjoint targets and MODEL/CLIP-only slots. Preserve captured CLIP biases and emit stock-loadable CLIP export aliases.
Remove the Legacy optimizer registration, both WanVideoWrapper-specific nodes, obsolete bridge UI and bundled legacy example. Document replacements and add stock-loader/file-stack/export parity checks to CI. Existing workflows using removed nodes require migration.
Validate the staged tree: 1064 Python tests and 69 subtests passed; 3 CUDA-only skipped; JS migrations and real ComfyUI round trips passed. Keep the rejected H3 search prototype and unrelated plans out of this release.
