Process-supervised RL for a multi-step reasoning agent - DAPO + a learned Process Reward Model training a Qwen3-8B Planner

从“为什么能去掉 critic”讲到“训练为什么学不动”：手算组内优势，拆解奖励与归一化，串起 Dr.GRPO、DAPO、GSPO 的改进动机。中文推导、核心代码、训练排坑，含 37 道章末练习与参考答案。

让 RL 工程里的坑不再只活在某个人的经验里。**当前是一个 demo ——** 只给结构、不给内容：36 个纯文本 Markdown 节点 + 一个只查自洽、不判对错的校验器 + 一个离线确定性检索器（无模型）。 | Make RL engineering pitfalls survive beyond one person's memory. **A demo —** structure, not content: 36 plain-text Markdown nodes, a consistency-only validator, and an offline deterministic matcher (no model).
