Ripe or Rotting

A six-stage simulation from banana chemistry to a fly deciding to land and feed: 14 days of ripening and yeast fermentation, volatile emission, a turbulent filament plume, 59 receptors mapped onto 52 olfactory neuron types and taste classes, the 165,122-neuron MaleCNS v1.0 graph run as a spiking network in four hunger states, then surge-and-cast flight. The validation table is where to look: four of its nine checks pass and three fail outright, including attraction across 108 odorants at r = 0.06. Flight and feeding rules come from behaviour data, not from the brain.
