A series, record or list message declares its shape instead of riding DType.JSON, so a widget binds a shape rather than some JSON and a wrong binding is refused before anything runs. A list declares its item type, which is what keeps list[float] expressible for a pipeline. On top of that: an agenda over a list, a notification over a record, and a dashboard alert channel that publishes engine faults as one — so a panel can show what went wrong without a flow wiring it by hand. Also: only None means a node published nothing, a falsy value of the wrong shape is now the named error it always should have been; and the gauge's readout says its size is viewBox geometry rather than type scale.
