Análisis Detallado
A01: La simplicidad tiene coste exponencial
El controlador creció de 83 a 184 líneas en un único método manejando 13 responsabilidades. El monto del descuento de early booking se analiza desde la cadena discount_reason (str_starts_with + explode) — un hack frágil.
Final Verdict: A01 is a trap. It seems cheap upfront but becomes exponentially expensive. Use only for short-lived prototypes or when you're absolutely certain complexity won't grow.
A02: Problema del Servicio Dios
El controlador se mantiene en 30 líneas pero toda la complejidad se trasladó a un 'Servicio Dios' de 172 líneas. El patrón Repository desvincula infraestructura pero no reduce complejidad algorítmica.
Final Verdict: A02 is a solid middle ground. It's better than A01 for testability, but you're still stuck with a monolithic service layer. Good for teams transitioning to cleaner architecture.
A03: Duplicación de estrategias
Phase04PricingStrategy duplica toda la lógica de BasicPricingStrategy solo para añadir 3 métodos. Buen equilibrio pero necesita refactorización para evitar duplicación de estrategias por fase.
Final Verdict: A03 is the practical choice for many teams. It offers good testability, clear separation of concerns, and a structure that maps well to business concepts. Needs refactoring for phase-based evolution, but shows the value of strategy-based design.
A04: Escalabilidad horizontal
Mayor coste inicial (22 archivos, 1139 líneas) pero escala horizontalmente: cada nueva regla es un nuevo archivo Decorator, no código modificado. Builder + Decorator significa que Fase 05 apenas toca código existente.
Final Verdict: A04 is for domains with frequent rule changes and teams comfortable with design patterns. It delivers on the Open/Closed Principle, but requires discipline and architectural maturity. The investment pays off in systems that evolve over years.

💡 Key Insights
1. Cost Distribution Matters
A01 looks cheap initially (6 files) but concentrates all cost in one fragile point. A04 looks expensive (22 files) but distributes cost across independent units. The question is: where do you want the complexity to live?
2. Controllers Are Not the Bottleneck
A02, A03, and A04 all keep controllers thin. The real challenge is where business logic lives. Moving logic out of controllers to services doesn't reduce algorithmic complexity—it just relocates it.
3. Extensibility vs. Simplicity Is the Core Trade-off
A01 is simple but brittle. A04 is complex but extensible. A02 and A03 sit in the middle. Choose based on your domain's mutation rate and team's architectural maturity.
4. No Silver Bullet
Each architecture makes trade-offs. A01 trades long-term maintainability for speed. A04 trades initial complexity for long-term flexibility. The "best" architecture depends on your specific context.
👥 Recommendations by Team Context
Startup / MVP Phase
Use A01 or A02. Speed matters more than perfect architecture. Iterate quickly, refactor later.
Growing Product
Use A02 or A03. You need better testability and clearer code organization. Domain is getting complex.
Business Rule Variability
Use A03. Business rules vary by product type or context. You want to map code to business concepts.
Rapidly Evolving Rules
Use A04. Rules change frequently. You need zero-modification extensibility and strong design discipline.
