NodePortMember

Remarks

The case IEditProvider's own remarks name: "a graph node's ports are described by the node". A port is not a field of anything — its value lives in Values, keyed by the port's name, because that is what survives a save and an undo. No generator describes it and no reflection pass can find it, so before this the only way to edit one was a panel that knew about ports, which is what NodeInspector used to be.

⚠ An InspectorMember rather than a bare IEditMember, and that is the whole point. The narrow contract would have been enough to write a port; it would not have got the port a drawer, a reset button, a tooltip or a row. Deriving from the inspector's descriptor type is what ReflectedMember does for the same reason, and it is what puts a node's ports into the ordinary inspector panel instead of a second one written by hand.

⚠ The lanes are the storage and the value is what a person edits. A port is one to four floats on the node; a row wants a float, a bool, an int or a Vector3. MemberType is the second of those, and the conversion in both directions is here so that every consumer — a drawer, a binding-path, the copy-property command — sees the shape it expects.
