the pulse of the cybergraph. syntropy measures order in bits β the key metabolic factor of superintelligence
meaningful cyberlinks raise it. spam and noise lower it. the tru computes syntropy every block in consensus. high syntropy = structured, connected, useful graph. low syntropy = noise dominates
syntropy = aggregate information gain across all neurons in an epoch. a neuron whose cyberlinks sharpen collective certainty contributes positive syntropy. a neuron whose cyberlinks add noise contributes negative syntropy. the BTS score $s_i$ is syntropy measured at the level of one neuron: how many bits of information that neuron added to the collective picture.
