pi0.5 Bin Pack Reward Recap - Positive Only Fix

Fine-tuned pi0.5 checkpoint for coffee capsule bin packing, rerun after the advantage-token placement and valid-index persistence fixes using positive-only reward recap semantics.

Experiment

• Config name: pi05_bin_pack_coffee_capsules_recap_positive_only
• Run type: experiment
• Objective: rerun bin-pack positive-only recap after fixing advantage-token placement, config-aware valid-index persistence, and shortening the run to 50k steps

Dataset

• 9 HuggingFace datasets: bin_pick_pack_coffee_capsules plus 8 DAgger rounds
