Holy moly, what an exceptional puzzle with such a tight logical path (I mean really tight), and also probably one of the most intense puzzles that I've tried from you.
This had me on the edge of my seat throughout the solve and every deduction, even if it's small, felt so valuable and all of them served for the wonderful breakthrough in the mid solve.
