-# Qwen3.5-27B Nanoclaw 多轮 GRPO — VERL 0720 + NPU SP1/31K 长轨迹全优化版
-#
-# 关键修改：
-#   1) 入口改为 python3 -m verl.trainer.main_ppo，不再使用 recipe.grpo_mindspeed_mm.main_ppo；
-#   2) 不再使用 MM_CONFIG_FILE / MindSpeed-MM YAML；
-#   3) 显式 text-only：data.return_multi_modal_inputs=False；
-#   4) 数据输入改为 Nanoclaw base_tasks 目录，不再使用 Retool parquet/json；
-#   5) 保留 27B 作业验证过的 HCCL buffer 与端口范围，降低 HcclAllreduce socket/资源压力；
-#   6) 默认 val n=1、log_val_generations=10，降低验证额外资源压力；
-#   7) 使用 FSDP2、reshard-after-forward、CPU offload policy、gradient checkpointing 和 activation offload；
-#   8) 使用最新版 VERL V1/TransferQueue 和 nanoclaw_recipe，并按参考 YAML 的训练意图映射优化器与 KL；
-#   9) 恢复正式训练所需的 22768 response / 16384 assistant 长轨迹预算；
-#  10) actor/ref 的全词表 entropy 使用 256-token 分块；
-#  11) 启用分块 Torch LM-head，避免完整 logits + NPU cross entropy 的多 GiB 峰值。
