/**
 * Defense-in-depth on top of the grid's defensive `setState`: strip anything the
 * reasoner returned that the {@link GridSchema} does not advertise, so the applied
 * patch is a faithful, predictable record and the UI can report exactly what was
 * refused. Drops, with a warning each: sort on unknown / non-sortable columns or
 * invalid directions (and extra entries on a single-sort grid); filters on unknown
 * columns or with operands invalid for the column; column-layout entries on unknown
 * keys; selection / pagination when the grid disables them; out-of-vocabulary
 * grouping / pivot / aggregation fields; and any slice outside the documented
 * {@link StatePatch} surface. Used by the view-state tools before `applyState`.
