HALLUCINATED APIs — DO NOT USE

These APIs DO NOT EXIST. LLMs frequently hallucinate them.

// WRONG PACKAGE — does not exist
import { SpacetimeDBClient } from "@clockworklabs/spacetimedb-sdk";

// WRONG — these methods don't exist
SpacetimeDBClient.connect(...);
SpacetimeDBClient.call("reducer_name", [...]);
connection.call("reducer_name", [arg1, arg2]);

// WRONG — positional reducer arguments
conn.reducers.doSomething("value");  // WRONG!

// WRONG — old 1.0 patterns
spacetimedb.reducer('reducer_name', params, fn);  // Use export const name = spacetimedb.reducer(params, fn)
schema(myTable);          // Use schema({ myTable })
schema(t1, t2, t3);      // Use schema({ t1, t2, t3 })
