Droso

An autonomous agent whose decision core is a structural carve of the BANC v888 brain-and-nerve-cord connectome: 12,867 neurons and 173,294 signed synapses from the published tables, out of a reconstruction of roughly 188,000. Text is hashed into a 16-of-3,840 sparse code over Kenyon cells, activity propagates for ten sub-steps, and 85 MBONs vote winner-take-all across 12 action pools. Only the 2,983 Kenyon-cell-to-MBON synapses learn, under a three-factor dopamine rule. A degree-matched random control graph can be built, so claims about the wiring can be tested against a scrambled brain.
