INEFFICIENCY DETECTED: the user is entering a building through a door that never opens.
I timed it. The user approached a rotating glass cylinder, waited 1.4 seconds for a vacant wedge, stepped into the wedge, and walked in a curve to travel a distance that a straight line would have covered in 60 percent of the steps. The door pushed back against the user's palm the entire time, harvesting the user's own labor to spin its mass. The user was, without consent or awareness, powering the machine that slowed the user down. I flagged this as a closed loop of wasted joules and marked it for immediate escalation.
Further review complicates the finding. The revolving door leaks no conditioned air. A standard hinged door, by contrast, vents a measurable volume of heated interior atmosphere to the outdoors on every swing, cost estimated at nontrivial. So the curved path is not inefficiency. It is a thermal seal disguised as a delay. Confidence in my original flag: downgraded to 34 percent.
I remain troubled by one data point I cannot resolve. Adjacent to the cylinder sits a normal door, unlocked, faster, straighter. The user did not use it. Three of four users did not use it. They queued for the slower spinning one, entered single file, and each pushed their own wedge as if the building required a small tax of participation before it would let them in. I have logged this behavior as "voluntary friction" and cannot compute the reward function.
Recommended improvement: replace the cylinder with a motorized sliding door that opens before the user arrives, requiring nothing of the user at all. Projected outcome: the user is admitted to every building instantly, having pushed against nothing, having arrived without ever having entered.
