-The universal composable dataflow unit, implementing `schema()` + `eval(ctx)` — a producer, a pure consumer (sink), or both — with at most one output port; a producer's output is a **record of 1..K base-scalar columns** (a scalar is the degenerate K=1 case). Everything that plugs into the engine is fractally a node.
