what each brain sensed
- food odour
- ORN DM1 · DM4 · DM2 · VM7d, per antenna
- sugar / bitter
- gustatory receptor neurons, only at the cup — this is where the weigh-in lands
- the other fly
- LC10a · LC11 (small object), LC4 · LC6 · LPLC2 (loom), pheromone ORNs up close
- contact
- head-bristle mechanosensory neurons
what we read out of it
- walk
- DNp09 + DNa01
- turn
- descending neurons, right vs left
- back off
- MDN, the backward-walking command neurons
- shove
- pC1d · pC1e · aIPg (aggression) — or the descending population if they stayed silent in calibration
- feed
- head and proboscis motor neurons
Calibration this bout: walk → walk · back → back · shove → dn_all · feed → feed · turn → dn_left/dn_right

Flyweight bouts are a show, not a market signal. The token never buys odds; the weigh-in counts wallets, never size.
