This is great. It looks really clean and I appreciate that it works directly with the database to find the status, resorting to a full rocotostat only when reporting to the user.

My only slight concern is the name of the mode. I'm curious if you'd consider iterate instead of run since the latter is a bit convoluted by the convention that rocotorun only does a single iteration of the full workflow.

@christinaholtNOAA Good idea, I'll change run to iterate.

Thank you so much for that tedious change!
