Classification in trialdiff is transparent and rule-based. A rule is a
named predicate evaluated against the long change register produced by
as_register(). Rules are applied in priority order; the first matching rule
determines the primary category, while every matched rule is retained in the
category_all column so that nothing is hidden.
