Liveness probing must bypass the fallback chain and connect directly to each route, otherwise the chain's fault tolerance will swallow the failure signals.

UnverifiedAny single node failure in Chain Replication breaks the entire chain, so fault detection and chain reconstruction mechanisms must be introduced to achieve high availability.74% similarUnverifiedIn terms of fault tolerance, Chain has virtually none—one wrong step causes everything downstream to collapse with no ability to retry—whereas Graph supports retries, fallback logic, and checkpoint-based resumption.70% similarUnverifiedA fallback chain strings multiple model endpoints together by priority, automatically trying the next priority when the primary route fails, but it cannot distinguish temporary failures from permanent ones.70% similarUnverifiedIn an Agent system, an error in any intermediate step can cause the entire pipeline to fail, making comprehensive logging and error-retry mechanisms a necessary guarantee for stable operation.69% similarUnverifiedUpstream and downstream dependency relationships exist between nodes, and deleting or modifying a node may trigger a chain reaction that causes downstream node execution to fail.69% similar
