So, the issue I’m currently working on w/ 3.0 which is that address_mapper makes a request with types outside the root subject types / selectors that are specified by the scheduler. options 1 figure out the subgraph / updating existing graph when a root is requested that isn’t already in the graph 2 tweak address mapper’s usage so that the types it asks for are covered We’ll need 1. eventually anyway, so I could go that way. 2 is probably easier. I’m giving 2 a shot to see if I can discover any other issues
