I did run it. same_column can be ambiguous if a neighbour overlaps its x-band, but it doesn’t pick a “wrong cell”: it joins all overlaps. Small drift alone stayed correct. The gap is real: we can detect multiple candidates, but don’t surface uncertainty yet.

Thanks for testing! It depends on the rule: “Same Column” uses the header’s relative position, while “Relative → Below” searches only below it. Increasing X tolerance can capture adjacent columns—was that the issue? “Position on Page” uses fixed X/Y coordinates.
