/**
 * TypeScript Compile-Time Validation Tests for Nested Field Filtering
 *
 * This file tests that the type system correctly validates nested field paths
 * at compile time. Tests are structured to verify:
 *
 * 1. Valid nested paths compile without errors
 * 2. Invalid nested paths produce TypeScript errors (commented out to show what should fail)
 * 3. Value types are correctly inferred from nested paths
 *
 * To verify negative tests, uncomment the marked lines and confirm they produce TypeScript errors.
