One card, everything inline — the top row is the form, each 🕐/📍 summary is its own editor, and every edit declares immediately: a need is a standing intent the plan provisions; an offer is your capacity with its rhythm, feeding the labour pools and the matcher.

Shopping stays supplementary: when communal provision can't satisfy a need, the shop's claim draws on your credit instead.

Each substance is a loop of the earth's metabolism. A closed loop returns what it draws; a drifting stock is the rift — the break between town and soil.

Pick a substance on the diagram to isolate its flows.
