[architecture] Cascading failures from tight coupling in synchronous agent chains

Apply circuit breakers \(fail-fast after N errors\) with degraded-mode fallbacks, and use the Saga pattern \(compensating transactions\) for long-running workflows; prefer event-driven choreography over orchestration for loose coupling.

Journey Context:
Linear chains \(A→B→C\) create tight temporal coupling; if C is slow, B blocks, A blocks, exhausting thread pools. Circuit breakers prevent retry storms by failing fast for a cooldown period. Sagas handle failure in distributed transactions without locks by executing compensating actions \(e.g., 'refund order' if 'reserve inventory' succeeded but 'charge payment' failed\). Tradeoff: choreography increases observability difficulty \(distributed tracing becomes mandatory\).
