Architecture Trade-offs
The decisions that come up in real design reviews — event-driven vs request-response, CQRS, service boundaries, sagas, idempotency, and the arithmetic of synchronous chains.
Twenty questions on the trade-offs that actually get argued about in design reviews: when an event beats a call, what CQRS costs, where a service boundary belongs, how sagas undo work, and the arithmetic that makes long synchronous chains a bad idea.
You get a score at the end, not a breakdown.
