sim06 — Termite Mound: Trace→Actor Crossing (H7)
Termites deposit soil pellets laced with cement pheromone (Grassé stigmergy). Does the accumulated trace field cross from a passive coordination signal to a self-maintaining actor? Baseline (decaying trace) vs. self-maintenance (structure re-emits pheromone).
