I think the litmus test on how the Russian campaign is going and how the Ukrainians are actually holding up will be the battle at Krasnahorivka, SE from Avdiivka, west from the city of Donetsk.
The front here stands still for long, basically form 2014 it seems, and the place is fortified strong. It's larger than all these villages the fights are going over. The line is solid, the routing, withdrawing brigades are relatively far to the north, so no immediate danger for the flanks to be exposed.
Now the Russian army moved onto the town, brought the fights into the southernmost streets. There was at least in incursion, which the Ukrainians beaten back.
How long will it take for the Russians to take the place - if they will be able at all. If they roll through in 2 weeks... that would be impressive.

At the situation at Robotyne. It sounds like another "meatgrinder" where units can be thrown into by both sides, and probably both sides thinks that they trap the other there. Like at Bakhmut. I don't really expect much territorial gains for now there, but I think the situation favors Russia. Every unit stuffed into that cauldron by Ukraine, one less unit to worry about elsewhere.
