COLUMN MAPPING — reorder OUTPUT columns (drag)
Output columns are reorderable by dragging. The leaf bullet becomes a grip-horizontal on every
writable output column to signal it. Drag starts from either the grip or the column icon. A live
insertion line shows where the column lands — between two columns, above all, or below all. Reordering rewrites
the output port's dataAsset.columns order; edges follow automatically.
Try it: grab an output row by its grip (or its column icon) and drag up/down — watch the blue insertion
line snap to each gap; release to drop. Input columns keep a plain bullet (reflected / not reorderable).
id has no expression (plain copy); full_name/total are mapped; created is unmapped.
