### What is the problem the feature request solves?
Follow up for #5323
We only report plain-column (identity) sort orders right now. Iceberg also
allows sort orders on a transform of a column — bucket, truncate,
year/month/day/hour, void. To use these we'd recompute the same transform and
compare on it, matching Iceberg's per-type comparison exactly (including quirks
like UUID ordering).
This is more surface and more correctness risk, so it should come with
per-type fuzz checks against Iceberg's own comparators before we report these
orderings.
