Report #56987

[architecture] Cascading latency and resource exhaustion as slow or failing agents choke the entire pipeline, causing retry storms

Implement per-agent circuit breakers \(failure threshold: 5 errors/60s, timeout: 30s\) with fallback to cached degraded responses or alternative agent paths

Journey Context:
Naive retries amplify load \(thundering herd\). Circuit breaker tracks failure count in sliding window; when threshold exceeded, fail fast for cooldown period \(30s\). State machine: Closed \(normal\) -> Open \(failing fast\) -> Half-Open \(test request\). Critical: distinct circuits per agent/tenant to prevent bulkhead violations. Fallback must be safe \(stale cache > error\). Tradeoff: temporary unavailability vs system collapse. Essential for high-throughput agent meshes.
