Report #71487

[architecture] Synchronous human-in-the-loop blocking causing cascade latency

Implement asynchronous checkpointing with speculative execution and sagas: agents continue processing assuming optimistic path while human review queues asynchronously; if human rejects, execute compensating transactions \(saga rollbacks\) to undo speculative work; use event sourcing for state reconstruction

Journey Context:
Waiting for human approval on every uncertain step kills throughput and breaks timeouts. Asynchronous checkpoints decouple human latency from agent processing. Speculative execution accepts computational cost of potentially discarded work in exchange for latency. Sagas \(compensating transactions\) undo side effects when humans reject, avoiding distributed locks. Tradeoff: complexity of writing compensating logic vs synchronous simplicity. Event sourcing provides audit trail for human review. Alternative of skipping human review accepts risk of undetected errors.
