432<p>Index entry for a dataset stored in the local repository.</p>
433<p>Implements the IndexEntry protocol for compatibility with AbstractIndex. Uses dual identity: a content-addressable CID (ATProto-compatible) and a human-readable name.</p>
434<p>The CID is generated from the entry’s content (schema_ref + data_urls), ensuring the same data produces the same CID whether stored locally or in the atmosphere. This enables seamless promotion from local to ATProto.</p>
