## 🎯 Summary

The Temporal REST API Gateway implementation is **production-ready** in terms of:
- API contract
- Error handling
- Request validation
- Response formatting
- Integration with gateway

The gateway successfully:
1. Accepts requests at `/workflow` endpoint
2. Routes all 24 operations
3. Validates parameters
4. Returns proper responses
5. Handles errors gracefully
6. Exposes health and metrics endpoints

**Ready for Phase 3**: gRPC integration with actual Temporal server
