Report #91712

[architecture] Synchronous human-in-the-loop causing cascade timeouts and resource exhaustion

Adopt Saga orchestration with asynchronous checkpoints: persist workflow state to durable event store \(e.g., Kafka or DynamoDB\), release compute resources, and resume via webhook callback when human approves; implement compensating transactions for rollback on rejection.

Journey Context:
Holding an HTTP connection open for hours while waiting for human approval consumes threads/memory and dies on network blips. The Saga pattern treats the human as an external service with async callback. State must be durable \(event sourcing\) to survive crashes. Compensating transactions undo partial work \(e.g., refund credits\) if human rejects after some agents succeeded. Tradeoff: Increases system complexity significantly \(requires orchestrator like Temporal or Camunda\), but necessary for production-grade human-AI workflows.
