/**
 * Edge case: derive with a .map() result as input, NO captures in derive callback,
 * and NO explicit type annotation on the callback parameter.
 *
 * This tests the scenario where:
 * 1. ClosureTransformer transforms .map() to .mapWithPattern()
 * 2. ClosureTransformer does NOT transform the derive (no captures)
 * 3. SchemaInjectionTransformer needs to infer the argument type from the input expression
 * 4. The input expression is now a synthetic mapWithPattern node
 *
 * Without proper typeRegistry lookup, the schema might fall back to `unknown`
 * because checker.getTypeAtLocation() doesn't know about synthetic nodes.
