Words have many meanings: senses, number, and the world model per word

Each word needs a world model: singular is not plural (graph is not graphs, and 'graph of graphs' is not 'graphs of graphs'), and the same word means completely different things across industries — a graph is a network graph here, a chart in a boardroom, a function plot at school. The thought exercise: author three to five senses per word, let people switch to THEIR definition, and programmatically show what stops applying (a graph that is a diagram is not fractal). Two addenda from the same day: layers must hold MULTIPLE engines side by side (pass-through itself an engine, include it or block the stream), and every engine must declare its input/output schema — including a fractal mode where one engine is a full WCLM inside.
