Recipe families

Family	Codes	Notes
BC-only	`sb1–sb4`	DINO/ResNet × 20%/full
Frozen → CCIL	`fd` / `fr`	Frozen encoder, scratch head
State → CCIL	`st` / `su`	TF / UNet
FT BC → CCIL	`d` / `e`	Warm-start head from BC
Sequential → CCIL	`s` / `sa` / `sc*`	Seq-B / A / C SSL → freeze → CCIL

expert_only = latent FT on expert demos only (--expert_ratio 1.0)
expert_aug = expert + CCIL backward_euler_fast augmentations

Not in this release

seqa_resnet/data_full (no Seq-A ResNet full tab in Square grid)
obsolete dated HF prefixes square20_* / square_r1_* (removed earlier)
contaminated premature-resume dumps (archived under output/arxiv_premature_resume_20260722/)

Caveats

Contaminated premature-resume FT/sa3 weights were removed from this repo (old dated prefixes deleted). ft_* / seqa_resnet here are corrected reruns where applicable (d1/e1/e2/sa3 via rerun wave).
CCIL after strong BC is not guaranteed to improve Square (see e1: EA≈EO).
seqa_resnet 20% (sa3) remains near-zero after the corrected rerun.

Eval example

python eval_checkpoints_multi_seed.py \
  --ckpt ./state_tf/data_full/expert_only/best.pt \
  --output_dir ./eval_out --n_seeds 3 --n_test 50 --base_seed 42 \
  --success_threshold 0.5
