Report #21221

[architecture] Multi-agent system halts indefinitely waiting for human approval because no timeout or fallback exists for human unavailability

Implement bounded time delegation with automatic escalation hierarchies: human → senior human → autonomous fallback with differential privacy noise injection \(to limit individual record risk\). Use circuit breakers that trigger autonomous mode when HITL queue depth exceeds threshold or latency SLA is violated.

Journey Context:
Synchronous HITL creates single point of failure. Asynchronous approval queues are necessary but require graceful degradation. Differential privacy allows autonomous action on sensitive data by adding calibrated noise, protecting individual privacy while maintaining statistical utility. Tradeoff: decision quality \(noisy data\) vs availability. Critical for healthcare or financial approval workflows.
