 Redis Search indexes require logical database 0, so vector-store URLs and clients
 must select database 0 (the default).
 
+When upgrading an existing `RedisContextProvider` index, stop older writers and

 Choose `storage_type="hash"` for non-null records with binary vector storage,
 or `"json"` for nullable fields/vectors and native JSON data. HASH rejects
 `None`, including `vector=None`; JSON preserves explicit null. Both support
