Mate is immediate: no flight square, no capture and no block.
Why it is mate
The chariot arrives on a line the defence cannot close. Chariots are the strongest pieces on the board and most finished attacks end with one, which is why a defender will trade almost anything to swap them off first.

Nothing here is an engine opinion. The position was solved by trying every legal defence to the full mate distance, so the claim that Red mates in 1 is a proof rather than an evaluation, and the first move shown is the only one that works. The defence in the line above is Black’s most stubborn try, not a convenient one.
