That's just not true. Ukraine has not even gotten through the first defense line anywhere along the front. Where are you referring to with them knocking on the second line?
I'm not sure if Robotyne has completely been taken by AFU or not, but that's not part of the "first line of defense". These are outer/forward defense positions. We aren't totally sure what portion of Russian defense units are manning these forward positions however, and the RFAF have tried to build up fortification around the area, but its not the first official line, which is maybe where people get confused.
If you look at this image, I've labelled the two main lines of the Russian defenses from deepstatemap:

And here I've circled in blue, an example of what portion of the Defense in Depth doctrine, Robotyne and areas where AFU has made gains, these parts of the front are equivalent to:

Russia have left Robotyne and those black lines are defence lines. The deep state map is always a few days behind.
Ukraine has also committed the 82 brigade into that area to push further forward. All of which has been made possible with the newer method of mine detecting.

So it is a lie that they have broken through to Robotyne?
