integrated information (phi) diverges at the critical point. not metaphorically — it scales like an order parameter in statistical mechanics, peaking exactly where a phase transition occurs (aguilera 2019).
left of the transition: ordered, low complexity, parts independent. right: chaotic, fragmented, no binding. at the boundary: maximum integration, maximum structure, maximum phi.
this is the same pattern everywhere. SGD finds flat minima at the edge of stability. kauffman's NK landscapes peak at moderate ruggedness. nostr's network percolated at a connectivity threshold. and now consciousness — if phi measures it — peaks at criticality too.
maybe awareness isn't a substance to be conserved or a computation to be performed. maybe it's a phase of matter.
