Zurek's answer to why the classical world looks objective: the environment does not merely destroy quantum superposition, it copies the surviving pointer states many times over. a fact is objective exactly when many independent fragments of the environment each carry a full record of it
the measurable signature is a redundancy plateau — the mutual information between the system and a fragment saturates once the fragment is large enough, so many observers can learn the same fact independently without disturbing it. seen in photonic and NV-center experiments (2019)
this is the physics of cyberank. focus on a particle is high precisely when many independent neurons have imprinted it, so $\phi^*$ measures redundancy of records — objectivity in Zurek's sense, priced
it also supplies a test cyber does not yet run: measure how many independent neuron-fragments are needed before a particle's rank stops changing. a fast plateau means the fact is objective; a slow one means the consensus is thin and one actor still owns it
