Report #99292

[architecture] A crash or retry loses partial progress or repeats work across multiple agents.

Persist a versioned checkpoint after every agent turn; design agents to read the checkpointed state rather than relying on in-memory context, and make external tool calls idempotent.

Journey Context:
In-memory state dies with the process. In multi-agent workflows, retries can replay partial executions and cause duplicate side effects. Treating execution as transitions between durable checkpoints makes recovery deterministic. Combine this with idempotency keys so replaying a turn is safe even if the previous attempt partially succeeded.

environment: Long-running or stateful multi-agent workflows that must survive restarts, retries, or crashes. · tags: state persistence checkpoint idempotency fault-tolerance · source: swarm · provenance: https://langchain-ai.github.io/langgraph/concepts/persistence/
