ΔIaccess(T)=Iglobal(T)−Icollector(T)\Delta I_{\rm access}(T)= I_{\rm global}(T)-I_{\rm collector}(T)

Why this formula appears here

That motivates two access models. The global algebra score permits the optimal measurement on the entire declared horizon state. The causal collector score restricts the measurement to the world tube and duration of a modeled interior receiver. Their difference is an access gap, ΔIaccess(T)=Iglobal(T)−Icollector(T)\Delta I_{\rm access}(T)= I_{\rm global}(T)-I_{\rm collector}(T). This gap is another proposed observable. It prevents the phrase “information is in the horizon state” from becoming “one observer can gather it.” The global score is a capacity statement; the collector score is an engineering task constrained by causal geometry.
