Today's "Selected port" view flatly mixes the port (the node's wiring stub: name, id, type, its one-char port label) with the data asset it carries (the scratch table: parquet type, columns, on-disk path, the promote transition). Splitting them into two blocks makes it unambiguous what you're touching — and the new data label lands at the top of the DATA ASSET block, clearly a property of the asset, not the port. The port label (the L/R glyph) stays exactly as authored.
Pane chrome is hand-drawn scaffold; the amber-dashed block is the proposed new field. The rest mirrors today's real INFO tokens.
