Policy Atlas
52 所大学 × 12 项条款的编码矩阵。每格附该校官方原文中的依据语句、发布单位与来源链接；斜纹格表示该来源未就此条款作出表述。另报告各条款的一致度与未提及校数。
A coding matrix of 52 universities × 12 provisions. Each cell carries the supporting sentence from the university's official text, the issuing unit and the source link; hatched cells mark provisions the source does not address. Agreement and non-coverage are reported for each provision.

AI in the Application
52 所大学招生办公室与申请平台（Common App、UC 系统、UCAS）就申请人使用 AI 的公开表述，附官方链接与逐字原文。 52 所中有 24 所对本科申请人写明了 AI 使用边界。
What the admissions offices of 52 universities and the application platforms (Common App, the UC system, UCAS) publish about applicants using AI, with official links and verbatim text. 24 of the 52 state explicit lines for undergraduate applicants.

Student AI Use Guidelines
依据图谱中美国 30 所大学的比较结果制定，面向国际部高中生，中英双语。内容包括四档许可框架与统一的披露格式，并专章处理 30 校政策基本未涉及的两个问题：以英语能力本身为评估对象的作业，以及大学申请文书。
Derived from the atlas's comparison of the 30 U.S. universities, for international-division high-school students, in Chinese and English. It sets out a four-level permission framework and a uniform disclosure format, and treats two matters the thirty policies largely leave aside: assignments that assess English itself, and college application essays.

By university
52 pages每所学校设有独立页面，如 ai.policy.nestudy.cn/MIT（不区分大小写，/mit、/johns-hopkins、/麻省理工等写法自动跳转），包含该校 12 项条款的编码与依据原文、申请环节的 AI 规定，以及采集的官方文本。色带即该校在图谱中的一行：颜色越深，规定越明确；空白为未提及。编号只是资料编号，不代表排名： 01–30 为美国 30 所大学，31–52 依据 College Fair 的学校名单补充，包括美国文理学院，以及英国、加拿大、新加坡、日本和中国香港的大学。
Each university has its own page, e.g. ai.policy.nestudy.cn/MIT (case-insensitive; /mit, /johns-hopkins, /麻省理工 and similar spellings redirect), with its coding on all 12 provisions and the text it rests on, what its admissions office says about AI, and the official text collected. The strip is the university's row in the atlas: darker is more explicit; blank is not addressed. Numbers identify files, not a ranking: 01–30 are the 30 U.S. universities; 31–52 were added from the College Fair's list, including U.S. liberal arts colleges and universities in the UK, Canada, Singapore, Japan and Hong Kong.
核验方法
Verification
Traceability规范中的每一处数字断言在构建时与数据集比对，每条引文与其来源文件逐字比对，不一致则构建中止。当前 98 处断言、9 条引文全部通过。
Every numeric claim in the guidelines is checked against the dataset at build time, and every quotation against its source file; a mismatch stops the build. Currently 98 assertions and 9 quotations pass.
52 份来源文件由 52 个相互隔离的程序分别抽取，每个程序只读取对应学校的文件，不得使用关于该校的既有知识；随后由独立审计重读同一文件复核。
The 52 source files were read by 52 isolated passes, each limited to its own university's file and barred from prior knowledge of that institution, then re-checked by an independent audit against the same file.
所有引文与其所属文件做精确字符串比对；未匹配的编码降为“未提及”并记录，出现在其他学校文件中的引文标记为串源。当前 388/388 通过。
Every quotation is matched exactly against the file it claims to come from; an unmatched coding is demoted to "not addressed" and logged, and a quotation found in another university's file is flagged as cross-contamination. Currently 388/388 pass.
因此，任何一项编码都可以对照原文复核，如有误判欢迎指正。完整方法与局限见图谱「方法与局限」。
Any coding can therefore be checked against the source, and corrections are welcome. The full method and its limitations are set out in the atlas under "方法与局限" (Method & limitations).
