Lena spent the morning drafting a utility to calculate how many ways the team can arrange specialized monitoring nodes on a square grid. Mark mentioned that because these nodes are sensitive, the logic must ensure no two nodes share the same row, column, or diagonal path to avoid signal interference. For instance, if the grid is four units wide, the utility should find that there are only two possible safe configurations. Eva is waiting to review the code to ensure it can help the ops team plan their hardware layouts without any overlaps.
