Report #64502

[architecture] Unable to resume agent chain after human review or intervention breaks workflow continuity

Implement deterministic state serialization \(DAG of agent outputs \+ pending tasks\) at each HITL checkpoint; human approval triggers atomic state transition to next agent via event sourcing

Journey Context:
Many systems implement HITL as a blocking webhook that loses context if the human takes hours or days. The state must be serializable and resumable. This pattern treats the human as just another agent in the saga, with explicit state contracts. Prevents 'zombie' workflows where the chain hangs indefinitely or resumes in an inconsistent state.
