//! NextJS Ontology Sync Integration Test
//!
//! This test validates the complete workflow of:
//! 1. Base ontology (Task: title, description, status) → TypeScript types
//! 2. TypeScript types → CRUD component
//! 3. Type safety verification (tsc --noEmit)
//! 4. Ontology modification (add Task.priority with constraints)
//! 5. Regeneration and drift validation
//!
//! ## Test Structure
//!
//! - **Phase 1**: Base ontology → Code generation → Type safety check
//! - **Phase 2**: Modify ontology → Regenerate → Verify updates
//! - **Phase 3**: Idempotency and zero-drift validation
//!
//! ## Chicago TDD Principles
//!
//! - Real RDF graphs with Oxigraph
//! - Real file I/O and TypeScript generation
//! - Real TypeScript compiler validation
//! - Real container execution (chicago-tdd-tools)
//! - Verifies actual type safety, not mocks
