antipasto.py (PiSSA/lora_frozen_b/old-lora2r wrappers) is dead in the live path -- train.py/extract use lora2r.py, nothing imports antipasto. Move the 7 scripts that import it or the erase-era proj fns (rescore_deploy, eval_checkpoint_curve, verify_vhack_heldout, probe_distill, diag_cosine_dist, diag_pairs_compare, tt_erase_bench) to scripts/attic/ -- they need lora2r rewrites if resurrected. Live imports verified clean. Co-Authored-By: Claudypoo <288921227+claudypoo@users.noreply.github.com>
