📄 Description

Also validates that

  • The signal received by nodes
    • fires in the event of a timeout
    • fires in the event of an external trigger (user code calling abort on the associated AbortController)
    • propagates correctly from parent graphs into subgraphs
      • when subgraph is called from within a node w/o explicitly passing config
      • when subgraph is a node
