Report #68114

[frontier] Cascading failures when LLM API latency spikes, rate limits hit, or models hallucinate critical errors.

Implement Circuit Breakers for LLM calls: After 5 consecutive timeout errors, open the circuit for 30s and route to a fallback \(cached response, local small model, or degraded mode\). Use Bulkhead isolation: dedicate separate concurrency limits for 'critical path' vs 'background' agent tasks to prevent resource starvation.

Journey Context:
Teams treat LLMs as infinitely available, but they suffer cascading failures like any external service. Circuit breakers prevent a hung LLM from freezing the entire agent graph. The key insight is distinguishing between transient errors \(retry\) and persistent degradation \(circuit open\). Bulkheads prevent background research tasks from starving the critical response path. This adds operational complexity but is essential for production multi-agent systems where a stuck tool call must not deadlock the coordinator.
