The kit Select now passes displayEmpty:true (so a selected value="" option like an "All" filter renders its label instead of a blank control) and MenuProps.PaperProps maxHeight:320 (so long option lists scroll inside the popover instead of listing every record). Both apply via slotProps.select and are overridable per call site. Verified app-wide: no call site regresses (audit of all 74 usages).

Select value/option restricted to string (MUI sets the literal child value; string|number + onChange:string was a type lie). DataTable sortDirection uses ?? 'asc' so aria-sort is never undefined on the active column. StatusChip sx-merge drops undefined; Pagination clamps page into range; DataTable dev-warns on sortKey without onSort; Alert onClose JSDoc.
