This means that there is no "original" user graph. For portability and > misc architectural benefits, we would like to build the original graph first, > and have the runner override later. > Some runners already work in this manner, but we could integrate it more > smoothly, with more validation, via some handy APIs on e.g. the Pipeline > object. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
