Pull request overview
Resyncs the Chinese translation of ge_arrow.md to match the upstream QuantEcon source document, primarily correcting a substantive logic divergence in the risk-free pricing calculations while also adding translation metadata for headings.
Changes:
- Added
translation:frontmatter with title + heading mapping metadata for the document. - Updated
price_risk_free_bondandrisk_free_rateto sum the pricing kernel overaxis=1(row-wise), aligning with the documented formula (R_i = (\sum_j Q_{i,j})^{-1}). - Minor formatting cleanup at the end of the file (closing fence / trailing blank line).

Summary: 整体翻译质量较高，准确传达了原文的经济学和数学概念，术语使用规范且与提供的术语表保持一致。主要问题集中在Python代码块中意外添加了字体配置代码（这可能是仓库标准化处理的一部分，需要确认是否为有意为之），以及个别措辞可以进一步优化以提高流畅度。数学公式和整体Markdown结构保存完好，未发现语法错误。 数学公式和LaTeX代码块完整保留，格式正确 专业术语翻译准确且与术语表高度一致，如'阿罗证券'、'贝尔曼化'、'解算子'等 代码注释全部准确翻译成中文，保持了代码可读性 长难句的处理较为得当，保持了学术文本的严谨性 Suggestions:

Summary: The resync correctly added the translation metadata block with accurate heading mappings while preserving document structure and fixing a minor code discrepancy (axis=1) to match source. This review was generated automatically by action-translation review mode. |

Source commit:
eb30e4fThis PR resyncs the translation to match the current source document.
Reason: The target adds font configuration code (mpl.font_manager, FONTPATH, Source Han Serif SC settings) not present in source's import cell, which is i18n-related and not a substantive addition. However, there is also a substantive change: in price_risk_free_bond and risk_free_rate methods, the source uses np.sum(self.Q, axis=1) while target uses np.sum(self.Q, 0) (axis=0), which changes the computed values/logic - this is a CONTENT_CHANGE. Since both exist, and code logic difference could affect correctness, but no major textual content was added beyond i18n font setup, the primary substantive issue is the changed axis parameter in the risk-free rate calculation, representing a content change requiring verification/re-translation of code intent.
