What's New

🔧 Bug Fixes

Fix convert_citations dedup key from (inst, yr) to (inst, yr, url) — previously, facts from the same institution and year but different URLs (e.g., 西安交通大学 2023 with two different articles) were merged into one reference entry, causing body citation numbers to link to non-existent anchors. Now all citations are correctly matched and linked.

📄 Reports

Add 2 new zh reports on ancient Chinese bureaucracy (10 chapters, 22.4K chars) and the Grand Canal's economic impact (10 chapters, 21.9K chars). Refresh reports browser.

更新内容

🔧 Bug 修复

修复 convert_citations 去重键从 (inst, yr) 改为 (inst, yr, url)——此前同机构同年份但不同 URL 的事实条目在引用转换时被错误合并，导致正文编号锚点断链。现已全部正确匹配。
