Report #63911
[frontier] Multi-agent transactions fail halfway through leaving partial state and impossible debugging
Implement saga pattern checkpoints at each agent handoff using LangGraph persistence, storing full state snapshots so failed branches can rollback atomically and replay deterministically from last known good state
Journey Context:
Compensating transactions are standard in microservices but new to agents. When Agent A books a flight and Agent B fails to book a hotel, you need semantic rollback. LangGraph's checkpointer combined with saga orchestration \(local vs distributed compensation\) ensures agents can replay from last good state. This transforms agent failures from catastrophic state corruption into recoverable replays.
