Unrecoverable LoRA Variant Source

The exact LoRA fused-producer/materialization implementation is absent from the current source diff, untracked files, reachable history, reflogs, and dangling Git objects. Existing production fallback checks reject active LoRA in fused producer methods, but they are not the removed materialization candidate.

Only benchmark and prose evidence remains. Reconstructing source from that evidence would not be exact recovery.
