Static-R0 Matched GRPO on RaR-Medicine — step 30
This is the policy after 30 global optimizer updates of the matched static-rubric GRPO run (planned total: 48). It is intentionally separate from the OnlineRubrics/dynamic-rubric checkpoints.

The root files are a BF16 Transformers export for inference. The
original_checkpoint/ directory contains the exact original veRL/FSDP policy
parameter checkpoint and its tokenizer/configuration files. Optimizer,
trainer, and data-loader state are intentionally not published; the complete
resume checkpoint remains on Daisy.
