I pushed a change draft for Issue #237 , “run.graphs and result.graphs should be dictionaries, not arrays” Documents/ChangeDrafts/Active/sarif-v2.0-issue-237-graphs-dictionaries.docx This was the only place in the spec where an object was looked up by its id, but where the object was not stored in a dictionary indexed by that id. Please see the issue description for more details. We’ll move approval of this change at TC #23 on Wednesday 9/12. Thanks, Larry
