Source desk opening
Evidence can belong to one primary thread and several connected threads. The thirteen fields organise discovery without breaking health into isolated silos.
Field foundation in progress.
The domain scope is now fixed in the thirteen-thread registry. Source monitoring and the first traceable evidence notes will be added here rather than published as an unstructured feed.
领域边界已经进入十三领域目录。后续来源监测与首批可追溯证据笔记会持续汇入这里，而不是形成无结构的信息流。
