What a slice-level benchmark certifies without the pixels: a label-file audit of seven public benchmarks, and a protocol-frozen random-sample screen of how often the check is reported

Background. Volumetric images are often labelled and scored one slice at a time. Shortcut learning, acquisition confounding and the inflation caused by slice-level splits are documented, and a pixel-free positional baseline is itself prior art; what is unmeasured is how much of a...
