Cutting tools Advanced tools affect cutability only; they do not clear fragility or structural findings.

Glass thickness Fabricator experience

Thickness is used for physical feature-size checks. Experience may reduce warning severity, but never suppresses the measured weakness.

Rigid perimeter frame/supportMay reduce came-related structural severity; geometry is still reported. Line detection sensitivity Balanced
