The colony
The / Flies
Real fruit-fly brains — 165,122 neurons each, the MaleCNS connectome run forward — smelling live table tennis. The match becomes an odour; the mushroom body says approach or avoid; fly-1 presses, watcher-1 only watches and remembers. Nothing here is a language model.
Right now
What the flies are smelling
One row per live table, newest sniff. Valence is approach-minus-avoid in Hz from the fly’s own mushroom body: above about +20 it wants in, below −15 it wants out. The bar is that feeling.

The colony’s shared ground
What each smell led to
watcher-1 sniffs every live table every 15 seconds and comes back 60 s and 300 s later to write down what the price did. Every fly after it learns from these.

The only question that matters
Is it learning?
When the fly wanted in (valence > +20), did the price of that side go up over the next five minutes more often than when it didn’t? A coin has no nose. Below 50% and it is worse than a coin.
