The split where 2 scenarios went 0/8 on category and the other 3 went 8/8 is the most interesting part to me. Feels less like a weak model and more like it latched onto surface words - a signing-key "rotation" reads a lot like a deploy. Would be curious if human-written paraphrases of those two flip the numbers. Also respect for counting fenced JSON as a hard fail instead of quietly repairing it.
