Pressure-test de arquitectura
"How would you de-risk this migration?"
Antes de la call, cargaste la propuesta, notas de arquitectura objetivo y 3 postmortems de migraciones parecidas. Cuando el CTO pregunta, Minuta sugiere: "I would de-risk it in two phases: shadow traffic for 48 hours, feature flags around the new path, and a rollback lever owned by one person. The main risk is data drift, so I would measure that before cutover." La call pasa de confianza abstracta a criterio de arquitectura.
