Unverified50% confidenceCautionExact time
When restoring from a LangGraph checkpoint, the most recent incomplete step may be replayed, so node logic must remain idempotent to avoid duplicate side effects (such as creating a branch twice or posting a comment twice).

VerifiedLangGraph combined with the Checkpointer mechanism can pause at any node, resume after auditing, and supports checkpoint-based resumption.76% similarVerifiedWhen resuming from a LangGraph interrupt(), the entire node is re-executed from the beginning; side effects that occur before the interruption must be idempotent or moved to after the interruption.75% similarUnverifiedIn LangGraph, looping logic is implemented through Conditional Edges, where the edge points back to the reasoning node when the task is incomplete and points to the termination node when it is complete.73% similarVerifiedLangGraph provides built-in retry, fallback, and error handling mechanisms, drawing on fault-tolerance strategies such as the circuit breaker pattern and exponential backoff.72% similarUnverifiedLangGraph's native retry uses the same approach every time and does not retain previous execution state after the process ends.72% similar
