BFS LoRA Surgery (save) applies the same rules and writes a .safetensors into models/loras,
for when a recipe is settled and you want it usable outside the workflow that produced it.
With no filename given, the name is derived from the rules themselves:
mylora__attn-x1.15__gate_up-b8_15-off__all-b16_23-off.safetensors. Names get sanitized, so a
type like *mlp* or a regex match still yields a valid file. The recipe also goes into the
safetensors metadata under bfs_surgery, next to the original metadata, so a shared file can
explain itself later.
Verified against the study output: saving the body-swap recipe produces the same 136 of 192
modules, and the effective dW matches the file produced by the standalone script to 3e-3
relative. The factors differ because the node scales only the up/B side while the script
split the scale across both, but the product is what the model sees.
