I opened up a new thread over here and filed a support ticket.
Support confirmed the behavior that I was seeing w/ artifacts: for an active branch this isn’t a great way to get artifacts because each new build appears to clear out the artifacts (it’s almost like the completed filter doesn’t work at all)
I posted a potential workaround w/ the v1 API in my thread. There may also be a way to retrieve this data w/ the graphql API or the v2 API (if you can figure out the best way to get a list of jobs) but I haven’t figured it out yet (love if someone else finds a better way)
