[architecture] Cascading quality degradation when low-confidence outputs propagate through agent chains

Implement confidence scoring with circuit breaker logic: route outputs below threshold to human reviewers or safe fallback agents; open circuit and pause upstream processing after N consecutive low-confidence classifications

Journey Context:
Agents often output confidence scores \(0.0-1.0\) but systems ignore them, passing low-confidence extractions to downstream agents that amplify errors. The circuit breaker pattern \(from distributed systems reliability\) prevents this: when Agent A's confidence drops below threshold \(e.g., 0.7\), stop the chain. Instead of failing, route to a human-in-the-loop queue or a conservative 'safe' agent. If low confidence persists \(e.g., 5 consecutive requests\), 'open the circuit' - temporarily reject new requests to Agent A entirely, allowing it to recover \(cooldown period\). This prevents resource waste on degraded models and stops error propagation before it compounds through the chain. Monitor circuit state as critical health metric.
