+从 ICLR 官方年份导航登记届次，读取对应 Papers 页面明确引用的 orals-posters/abstracts JSON。核对声明数量、分页状态及唯一 event ID；只下载公开程序元数据，不访问用户资料、PDF、海报、幻灯片或视频。`--year` 可限制年份；清单中的已采集数与数据库已入库数分别统计。
+
+官方程序中的 event 数不是论文数：同一篇文章可以有 poster 和 oral 两场展示。程序还会给负 sourceid 的 oral 展示生成占位 OpenReview 链接，这些链接不能作为真实论文标识。采集器核对原投稿编号、标题与作者后合并展示，优先使用正编号记录的真实论文链接；原展示编号和类型保留在源元数据中。
+
+同一投稿编号的展示标题可能有小幅修订。只有负编号 oral 与正编号原稿对应、至少两位作者完全一致且标题相似度满足严格阈值时，才保留为同稿的标题变体；该规则仅在一届官方程序内部生效，不用于跨平台模糊合并。
+
+只将 Conference 来源的论文视为 ICLR 主会录用，排除 Blog 和期刊转会展示，并在审计清单保存排除计数。2020/2021 旧数据允许依据官方主会 paper program 形成录用证据；无 forum ID 时保留 program 身份和匹配候选，不伪造标识。历史年度返回 404 会登记 unavailable，未来未发表届次登记 not_yet_published，其他访问或解析失败登记 blocked；这些状态都不能宣称该年已覆盖。
+
+主题、关键词使用 `iclr_program:topic`、`iclr_program:keyword` 命名空间。通用导入器按源记录刷新标签证据，保留同一论文其他源记录及 `custom:*` 标签。每年的 JSONL、manifest、`iclr-program-year-status.json` 和 `iclr-program-last-run.json` 保存实际范围、独立展示数、主会展示数、论文数、缺失摘要与缺失 forum 数。录用程序不能提供拒稿全集，公开投稿及拒稿补充仍需独立来源。

 ## 长期维护与更新
 
 1. 每次采集先核对来源、许可、可访问性、空闲空间和现有运行批次。保持低并发，遵守来源限流、重试与人机验证要求。
