Camera grouping, centered principal point, one radial distortion term and full-frame JPEG correspondence are hypotheses; rounded EXIF focal lengths are starting priors, not calibration. Capture sessions on October4 and9 are separate observations; shared visible tracks do not establish unchanged hidden components or the car's current state. Points are surface observations, not closed solids. Missing points do not prove empty space, access, operating clearance or a removal path. Pixel reprojection residuals measure reconstruction fit, not dimensional accuracy. The independent-camera comparison shares photos and differs in feature extraction; it is a sensitivity diagnostic, not an independent survey. The retained CAD requires a known scale and actual datum correspondences before any installed-frame change.",
