Code review of SerenityJS integration PR

[Copilot]

Comprehensive code review requested for the SerenityJS integration changes that implement Cucumber-based acceptance tests and refactor domain permissions.

Review Findings

✅ Architecture & Domain Design

• Clean DDD separation with proper aggregate boundaries and state transition guards
• Reservation request permissions correctly consolidated to single canEditReservationRequest permission
• State transitions use domain errors with explicit validation rules
• Reserved listing state correctly removed (derived from active reservations, not persisted)

✅ Test Infrastructure

• Screenplay pattern properly implemented with abilities, tasks, and questions
• Feature files organized by domain context (listing/, reservation-request/)
• Cucumber configuration uses appropriate tags and parallel execution settings
• SerenityJS dependencies correctly added to domain package

🔍 Minor Issues

Type Safety

• CreateListingAbility.ts:150 uses any - should use explicit type or unknown with guards

Test Fixtures

• Hardcoded '1.0.0' schema version repeated across test files - centralize as constant

Error Messages

• State transition errors could include current state for better debugging:

// Current
throw new DomainSeedwork.PermissionError('Can only accept requested reservations');

// Suggested
throw new DomainSeedwork.PermissionError(
  `Cannot accept reservation in state "${this.props.state}". Only "Requested" reservations can be accepted.`
);

⚠️ Blockers

• Build fails due to npm certificate chain issue in codegen prettier step
• Vitest config resolution errors prevent test execution
• Must resolve before merge

Recommendations

• Add JSDoc comments for public state transition methods (publish(), pause(), cancel())
• Document what canEditReservationRequest permission allows - may need finer-grained permissions for sharer-only vs reserver-only actions
• Consider adding integration tests for complex state transition scenarios
