What the preview returned
Every file below came from one free preview run on the licensed source image. The numbers quoted are the values the checks reported, plus measurements taken from the returned depth field. No physical result is claimed for this case.
Source readiness at approval
Reported 1920 px input, 98% usable tonal range, edge detail 0.028, and border clutter 0.237, which crossed the threshold into Review. This is the check that decides whether a cluttered photograph is worth a paid job.
Manufacturing checks at approval
Reported 1.69 mm tool-to-grid detail and 61 effective tonal slices. Measuring the returned field afterwards: the outer border band spans 99.2% of the full depth range, and its standard deviation is 73.5 against 55.3 in the subject area. The background therefore carries more depth variation than the subject, which is exactly why this source should be cropped or flattened before approval.
Failure notes
No physical result is claimed for this case. It documents the free checks and the measured behaviour of the returned depth field on a licensed cluttered input.
