llamacle_drgrpo_v1_step30 - DrGRPO RL on top of llamacle_v6_clean (step 30)

Continuation of ceselder/llamacle_v6_clean_step1875 via online Dr. GRPO RL on the 2,500 held-out FineWeb LoRAs from v6 pretrain. 32 prompts/cycle x K=16 rollouts (sub-batched 4xK=4), lr=7e-6, eps=0.2/0.28, NF4-DDP across 6 B200s, forward_ckpt_inject for backward (activation checkpointing).

This is step 30 of 80 (mid-run checkpoint).

Score progression (judge 1-10 mean over kept rollouts)
