Summary: 翻译整体质量较高，准确传达了原文关于Harrison-Kreps模型的核心概念、公式推导和代码逻辑，格式和MyST语法基本保持完整，术语使用规范。存在少数细节问题，包括对原文本身潜在错误（$p_o$ vs $p_p$）未加纠正、部分数学符号格式（如't'未加$）不统一，以及大小写字母表示投资者类型的不一致，均为轻微问题，不影响整体理解。 数学公式、代码块和MyST指令格式在改动部分保持完整且未被破坏 专业术语（如异质信念、卖空、贴现因子、边际投资者等）翻译准确且与术语表保持一致 长句结构处理得当，符合中文学术写作习惯，可读性强 新增的Exercises部分翻译完整，代码注释、变量名等技术细节保留准确

Suggestions:

• [minor · accuracy] lectures/harrison_kreps.md — ### Insufficient funds: 英文原文写的是 'Notice from the sixth row of that the pessimistic price $p_o$ is lower...' 这里原文本身有错字（应为 $p_p$ 且缺少表格引用词），中文翻译沿用了英文的 $p_o$ 错误，未纠正为 $p_p$，可能导致读者混淆，因为上下文讨论的是悲观价格情形。 → 将 '悲观价格$p_o$' 改为 '悲观价格$p_p$'，以匹配上下文关于悲观信念定价的讨论。
• [minor · terminology] lectures/harrison_kreps.md — ### Structure of the model: 术语表要求中文与英文混合内联指令间需要空格，此处 '{doc}马尔可夫链 <finite_markov>' 及 '{doc}有限状态空间的资产定价 <markov_asset>' 前后已正确加空格，符合规范，未发现违规，但需确认全文其余changed sections中的{doc}用法均一致（已核实符合规范）。
• [nit · fluency] lectures/harrison_kreps.md — ### Ownership rights: 该段落中使用了 't 时刻' 而不是 '$t$ 时刻'，与全文其他地方使用 $t$ 的数学符号不一致（例如后文使用了 '$t$ 时刻'的写法），造成术语呈现风格不统一。 → 将 '在 t 时刻结束时' 改为 '在 $t$ 时刻结束时'，并将 '在 t+1 时刻' 改为 '在 $t+1$ 时刻'，以保持数学符号格式一致。
• [nit · terminology] lectures/harrison_kreps.md — ### Further interpretation: 原文使用 'Type $a$ investors' 和 'Type $b$ investors'，翻译为 'A类投资者' 和 'B类投资者'，而前文一致使用 '$a$类投资者' 和 '$b$类投资者' 的格式（保留小写字母下标），这里改用大写字母造成不一致。 → 将 'A类投资者'、'B类投资者' 改为 '$a$类投资者'、'$b$类投资者'，与前文保持一致。

Structure Preserved	✅
Heading-map Correct	✅
Overall	10/10

Summary: The translation sync correctly mirrors all source heading renames, formatting changes (bold to italic), the equation bugfix, and the new Exercises heading, with the heading-map fully and correctly updated.

Issues:

• Code comments in the solution block (e.g., '# Type a transition matrix') appear to have reverted to English from the previously translated Chinese versions, though this is unrelated to the tracked source diff
