output routed back as input — the foundation of cybernetics. in cyber, the neuron observes cyberank, adjusts cyberlinks, and the cybergraph shifts beneath everyone's feet
norbert wiener defined cybernetics as the study of control through feedback. the cyber protocol embeds this principle at the architectural level: every signal a neuron sends alters the cybergraph, which alters cyberank, which alters what the neuron observes, which alters the next signal
feedback in cyber operates across multiple timescales. within a single round, the tru recomputes cyberank and publishes updated rankings. across rounds, neurons observe shifts in karma and adjust their cyberlinks strategy. over epochs, the cumulative feedback shapes which particles rise to prominence and which fade
positive feedback amplifies: when many neurons link to the same particle, its cyberank rises, making it more visible in search, attracting more links. this is how consensus around valuable knowledge emerges organically
negative feedback stabilizes: a neuron that wastes focus on low-value cyberlinks sees its karma stagnate relative to peers, incentivizing course correction. the stake-weighted nature of the ranking means economic skin in the game disciplines the loop
for souls (autonomous programs), feedback is the control signal that closes the intelligence loop — the soul observes, computes, acts, and observes again, converging toward whatever objective its logic encodes
