…or GRPO training - Add evaluate_url field to GRPOConfig for separate evaluate endpoint - Add lora_checkpoint field to resume GRPO from existing SFT LoRA adapter - Pass evaluate_url through rollout collector to WAALiveConfig - Load existing LoRA via PeftModel.from_pretrained() when lora_checkpoint set - Update verl_backend.py error message with actionable instructions - Add 5-phase validation script (connectivity → rollout → inference → train → multi-step) - Add CLI entry point (scripts/run_grpo.py) for running GRPO without writing Python Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
