[architecture] Agents silently passing low-confidence outputs downstream, causing compounding errors in multi-hop chains

Implement conformal prediction or ensemble disagreement to generate calibrated confidence scores \(0.0-1.0\). Enforce a tiered escalation protocol: <0.7 triggers a peer-agent verification \(second opinion from a different model\), <0.5 triggers a human-in-the-loop checkpoint requiring cryptographic attestation \(signed JWT\), <0.3 triggers an immediate circuit breaker and rollback to last known good state. Store all confidence metadata in a traceable audit log.

Journey Context:
Raw LLM log-probs are poorly calibrated and not comparable across models. Binary pass/fail loses nuance. The alternative is always using expensive consensus \(majority vote of 3\+ models\), which is too slow and costly. The right call is calibrated confidence with tiered escalation because it optimizes cost: high confidence auto-approves, medium confidence uses cheap peer check, low confidence uses expensive human time. This is essential for financial or medical agent chains.
