Same readings. Different places.
Two combined-instrument rows describe different kilometre ranges, yet repeat the same measurement pattern. That deserves more attention than checking whether each cell contains a number.
A C I D record links road, lane, range and test date to roughness, rutting and texture measurements. Those measurements must stay attached to their original location and survey context.
Find reused coordinates
One implemented check finds the same road, lane, date and coordinate reused across different ranges. Compare the source rows: a copied coordinate can hide behind otherwise valid field types.
Another compares the instrument-value vector across different ranges in the same road, lane and date group. At least three recognised measurement columns must be present for this check.
Compare complete measurement patterns
Build a comparison around the same road, lane and date with two different kilometre ranges. Check whether the coordinate was copied, then compare the recognised instrument columns together. Equal values in a single roughness column are insufficient to establish the repeated-vector condition described in the film.
The implemented vector comparison requires at least three recognised populated, non-zero measurement columns. Preserve blank and zero values according to their actual meaning. A repeated complete vector is a reason to inspect the export and source measurements; it does not prove that the survey was fabricated.
Respect the rule’s guards
Every included measurement must be populated and non-zero. The rule deliberately avoids treating blank or zero-filled, partially measured vectors as copied combined-instrument readings. Equal roughness alone is not enough.
An identical vector is a review signal, not proof of fabricated data. Inspect the original export and survey records, correct the actual cause, then rerun. Preserve unmeasured values honestly.
