I also separated in 2 like you did at some point, but I was not sure that no races exist between the 2 so I ended up removing it.
After more thinking I think we should be safe, we are iterating on 2 disjoint set of tasks (active+schedule vs failed+complete) and I don't see any trouble if an active task becomes complete or failed in the middle.

@MatMaul Updated.

I've also have updated the prometheus metric to use a LaterGauge so we don't have to worry about keeping it up to date
