⚠️ Target-Only Sections Removed

The following sections exist in the current translation but have no counterpart in the source document, so this sync removes them (the translation mirrors the source's structure). If the source deleted these sections, this removal is correct — merge as usual. If they are human-authored additions you want to keep, move them into a target-only file before merging (see adding content to a translated edition).

Criterion	Score
Accuracy	8/10
Fluency	7/10
Terminology	8/10
Formatting	8/10
Overall	7.8/10

Summary: This is a strong, technically precise translation across a large and mathematically dense set of changed sections. Equations, code, and MyST cross-references are preserved faithfully, and terminology is applied consistently with the provided glossary in the vast majority of cases. Minor issues are limited to small cross-file terminology inconsistencies (e.g., '结语' vs '结束语' for 'Concluding remarks') and a few stylistic/spacing nits that do not affect comprehension or build integrity. No blocking accuracy or syntax errors were found in the modified sections. Technical and mathematical content (equations, code blocks, cross-references) is preserved accurately across all eight files with no broken LaTeX or MyST syntax. Domain terminology (e.g., 卡尔曼滤波器, 观测等价性, 稳健性, 贝叶斯估计, 向量自回归) is applied consistently and matches the standard glossary conventions. Long technical passages (e.g., the Sargent-Surico model derivations, Hamiltonian Monte Carlo section) are translated with careful attention to preserving the logical and mathematical structure of the argument. Proper spacing conventions between Chinese text and inline MyST directives/code are followed correctly throughout the changed sections. Headings metadata in YAML frontmatter correctly maps English section IDs to Chinese headings as expected by the translation system.

Suggestions:

• [major · accuracy] lectures/ar1_turningpts.md — ## 实现 (Implementation section, class AR1 docstring): The AR1 NamedTuple docstring in the translated code was left partially untranslated in structure vs original but content is fine; however more importantly, in the 'A Wecker-Like Algorithm' section header translation the English 'time to next turning point' concept and index notation were preserved correctly. No major issue here upon closer check — retracting.
• [minor · fluency] lectures/lq_bewley_complete_markets.md — ## 借款人与贷款人经济: The phrase '因此，$R = \beta^{-1}$ 是一个均衡结果。' followed by a lone blank line with a stray space is slightly awkward but not incorrect; minor formatting/fluency roughness carried over from source spacing.
• [minor · terminology] lectures/lq_robust_bewley.md — ## 相关讲座: Heading '## 相关讲座' is missing the customary blank-line separation/spacing consistency seen elsewhere in the document (e.g., other 'Related lectures' sections elsewhere have blank line before), but this is a very minor formatting nit not affecting rendering.
• [minor · fluency] lectures/sargent_surico.md — ## 结束语: The term '结束语' is used here for 'Concluding remarks' whereas elsewhere in the same PR set (e.g., lq_robust_bewley.md, lq_robust_smoothing.md) the same English heading 'Concluding remarks' is translated as '结语'. This is a minor cross-file terminology inconsistency for the repeated heading. → Use '结语' consistently for 'Concluding remarks' across all files, or confirm '结束语' is intentional for this file.
• [minor · terminology] lectures/var_subsets.md — ## 例1：一个二元向量自回归 VAR(2): Heading translated as '例1：一个二元向量自回归 VAR(2)' inserts a space before 'VAR(2)' inconsistently with the no-space convention used for inline math/code elsewhere (e.g., '二元向量自回归VAR(2)' vs with space); minor style inconsistency, does not affect meaning.
