Add UI-agnostic model layer: typed grouped properties (string/int/float/ bool/enum/color/catalogue item(s)/value list), catalogue registry, port relations with color schemes and compatibility rules, ports, node/edge models, and DiagramDocument with change signals and JSON round-trip. Include a starter node library (source/tank/pump/valve/junction/consumer/ transformer) with matching SVG symbols, plus model+document tests.
