Recognize accepted RSS publisher DOI as an edition-scoped publication identity

 2024 年的官方节目单把两轨都放在 `Conference`，但提供 PMLR 论文自链接。该年仅采用组织方在 [2025 Position CFP](https://icml.cc/Conferences/2025/CallForPositionPapers) 明确链接的 [2024 Position 论文标题筛选](https://icml.cc/virtual/2024/papers.html?filter=titles&search=position%3A) 规则；同时保存规则页面的哈希。这个规则不用于其他会议或年份。官方节目单将 `guyard24a` 链接误写为 `theo24a`：只对这条已核查的映射额外要求标题精确一致、至少两名公开作者重合，不进行全库模糊匹配。
 
 导入与身份回填拒绝 ICML 2024 起 parser_version<3 或没有官方轨道证据的旧文件。已有主库中的错误轨道需要在独占维护锁内迁移原投稿事件、保留决定与来源关联；仅重新导入拆分文件会留下旧的主轨道事件，不能作为修复方式。完成迁移前，不把新文件直接导入现有库。
+
+### RSS 发表身份
+
+已核验的 `rss_proceedings` 录用记录与其他出版社来源一样，将 DOI 作为届次范围内的 `publication_doi` 投稿身份。这样同一 RSS 出版物先由官方论文集、后由 DBLP 导入（或反向）时可以共享一次投稿，并保留各自来源和决定观察。此规则不把节目显示编号当原始 OpenReview 投稿号，不把拒稿/撤稿升级为录用，也不跨届次合并历史。
+
+这不证明任意 DOI 的科学作品归属：导入前仍需核查原始标题、完整作者、版本和已有标识冲突。变更只作用于后续导入；不会自动回填、合并或改写旧 RSS 记录，旧记录需要独立审查计划。
