Knowledge Base
First-class entity
A canonical Baum-corpus object record classified as container set, tracked through the Objects census for identity, use, provenance, and book-level evidence.
Census Method
Identity & provenance
This registry keeps one continuing physical object as one entity across aliases, owners, repairs, state changes, and recurring book appearances. Components, coherent sets, magical substances, and persistent possessions may receive canonical records; generic environmental occurrences remain supporting corpus evidence rather than inflated top-level entities.
