Semantic Drag

add resistance when movement would break meaning

Running the actual pattern live via applyPattern() — switch the substrate, stack overlays, watch the signals, or reverse the dynamics. Not a mock.

"Semantic Drag" — add resistance when movement would break meaning. It has a viscosity layer (damp motion / calm a region), a link layer (ropes / cloth between neighbours), a tether layer (bind matter to an anchor), and a cohesion layer (flocking — pull toward neighbours). The active render stack is links, field-lines, trails, particles.

A derived friction recipe, not a natural field: dragging an object away from meaningful neighbors thickens viscosity while tether (spring) and links resist, and moving toward a valid relationship lets resistance fall away. The user can always override.

Reduced motion: valid/invalid guides with relation warnings and a drop-cost marker
Without motion: valid drop targets are listed; invalid moves show a warning and a labelled cost before commit
