🏗️ Architecture Validation

Hexagonal Architecture Compliance ✅

✅ Domain isolation: Zero external dependencies in domain layer
✅ Dependency direction: All dependencies point inward toward domain
✅ Framework-free testing: Tests run without NestJS
✅ Database agnostic: No TypeORM in domain
✅ Pure TypeScript: No decorators in domain layer
✅ Port/Adapter pattern: Clear separation of concerns
✅ Compilation independence: Domain compiles standalone

Build Verification ✅

cd apps/backend && npm run build
# ✅ Compilation successful - 0 errors

Test Verification ✅

cd apps/backend && npm test -- --testPathPattern="domain"
# Test Suites: 3 passed, 3 total
# Tests:       49 passed, 49 total
# ✅ All tests passing
