Report #87695

[architecture] Cascading failures when downstream agent is slow/unhealthy, consuming resources upstream

Implement circuit breakers on inter-agent calls that trip after 5 consecutive failures or 10s timeout; open circuit returns fast failure or degraded mode for 30s before half-open retry.

Journey Context:
Without this, retry storms amplify outages and exhaust thread pools. Exponential backoff helps but doesn't prevent resource exhaustion during prolonged outages. Circuit breakers \(from Release It\!\) isolate faults. The half-open state is critical: allowing one probe through prevents flapping. Critical for LLM-based agents where timeouts are common due to variable generation latency. Alternative is bulkheads \(thread pool isolation\), but circuit breakers are lighter for agent chains.
