OPAL PushT checkpoints

Private repo: helen9975/opal-pusht-ckpts

Multi-seed eval protocol (unless noted): 3 seeds × 50 episodes, success_threshold=0.95.

Packages are additive — later drops use new path prefixes and do not replace earlier trees.

Package When Path prefix What
Jul 15 2026-07-15 repo root (frozen_dino/, state_*, resnet_unet/, repro/) Frozen / scratch + Celia BC→CCIL repro (OPAL knobs: crop84 / bs640)
Jul 18 2026-07-18 ft_*, bc_h2_*, seqb_*, seqa_resnet/ OPAL knobs: FT→CCIL, h2 BC, Seq-A/B
Jul 20 k76b64 2026-07-20 k76b64/ Celia knobs (crop76 / bs64): FT, h2 BC, Seq-A/B, and frozen scratch

k76b64 knobs: crop [76,76], BC batch_size=64, DINO patch_hw=[-1,-1], dynamics patch [5,5], UNet [256,512,1024] emb 256.

Jul-15 frozen_dino/ / resnet_unet/ ≠ k76b64 *_scratch/ (different crop / batch size / UNet).

Not on HF (weka only): SSL probes, bc_h1_*.
