[architecture] Silent Consumption of Low-Confidence Agent Output

Implement confidence scoring with a circuit breaker pattern: if confidence < threshold, route to a fallback \(stronger model or human\) and temporarily halt the chain to prevent error propagation.

Journey Context:
Agent B consuming Agent A's output has no inherent measure of A's certainty. When A hallucinates or faces edge cases, it may produce plausible but wrong output that B treats as ground truth. Simple threshold checks are insufficient because they don't handle cascading failures across the chain. The circuit breaker pattern monitors failure rates or confidence scores; when confidence drops below a threshold \(e.g., 0.7\), the breaker 'opens', stopping the chain and triggering escalation \(human review or larger model\). This prevents 'poisoning' of downstream agents. The tradeoff is latency \(escalation is slow\) versus accuracy. It requires calibration of thresholds to avoid alert fatigue and ensure the fallback mechanism is actually more reliable.
