LoRA adapter checkpoint for a bounded ablation in the Qwen3 GRPO patch investigation.

Base model: unsloth/Qwen3-4B-Instruct-2507

Local source checkpoint: /mnt/disks/unslothai/datta0/cache/qwen3-grpo-patch/20260605_122046_swegym_q4b-kl02-sft20k-hardmulti-ec2analog-capped-v1_ee83de6/checkpoints/best_holdout

This checkpoint is an ablation, not the promoted frontier checkpoint. It starts from the Qwen3-4B KL02 hard-multi 20k adapter and adds a capped EC2 analog SFT mixture.

Held-out SWE-Gym Moto pass@8 evaluation:

The ablation was negative against the hard-multi seed9012 frontier and should not be promoted as the best adapter.
