The biggest issue for Ukraine here is that Sverdlikovo and Lebedevka are both quite isolated, with many km of open fields on 3 sides of the villages. Whilst this greatly aided them when Russia was trying to attack from Darino and Nizhnii Klin, its now hurting Ukraine as its significantly more difficult to get supplies and reinforcements into the settlement compared to other villages as they are constantly harassed by drones. The only viable option is to send them up from Basivka (over the border in Sumy), however Russia has been putting a lot of pressure of these reinforcements and supplies via constant drone strikes (video 1, video 2, video 3), which are destroying or knocking out equipment and troops before they can be used to defend Sverdlikovo. At this stage its highly unlikely Ukraine will be able to hold Sverdlikovo, and will be forced to retreat back to Lebedevka and over the border into Sumy.
At the same time as all this, on the northern side of the Kursk front Ukraine launched counterattacks in Kositsa over the past week, retaking the northern half of the village as well as the forest area on the west side. They are not out of the danger zone yet, as Russia still has a decently sized force in Russkoe Porechnoe which will certainly try to attack Kositsa again.
