[architecture] When to halt automated agent chains and escalate to human review before error propagation becomes catastrophic

Implement confidence scoring on every agent output with tunable thresholds; when confidence falls below threshold or variance exceeds bounds, open a circuit breaker that halts the chain and routes to human-in-the-loop review with full context preservation.

Journey Context:
Teams often build 'optimistic' chains that assume every agent succeeds, only discovering errors at the final output when debugging is impossible. Adding try-catch isn't enough because semantic errors \(hallucinations, subtle misinterpretations\) don't throw exceptions. The alternative is exhaustive validation at each step, but that's computationally expensive and slows the chain. Confidence scoring with circuit breakers provides a middle path: it assumes success but has a kill switch when uncertainty grows. The tradeoff is false positives \(unnecessary human review\) vs. false negatives \(undetected errors\); thresholds must be tuned per domain.
