We complete the microphysical specification of the local information-capacity sector of the finite-capacity latency–erasure theory by fixing the four remaining structural ambiguities left open by the first closure paper: the definition of the coarse-graining operator , the status of the patch-geometry factor , the normalization of the vacuum entropy sector , and the regime-transition rule selecting the local causal patch across weak-field, cosmological, and strong-field domains. Earlier FCLET work established that the local realized information content is obtained from a finite coarse-grained entropy , that the maximal local information capacity is bounded geometrically, and that the normalized occupancy field generates the emergent latency field . The present paper fixes the remaining open specification problem. We define as a physical entropy-selection operator built from admissible mode truncation, causal accessibility, and finite-resolution distinguishability. We show that is not a free fit parameter, but a derived geometric normalization associated with patch class. We set the canonical vacuum normalization by imposing vanishing occupancy in the renormalized Minkowski reference patch, thereby fixing the physical meaning of . Finally, we derive a patch-selection principle that assigns the relevant causal domain through a minimal capacity-consistent accessibility rule, allowing smooth regime transitions across FCLET applications. The result is a sharpened local substrate basis in which , , , , and are not only structurally defined but operationally specified. This removes the remaining ambiguity from the microphysical burden sector of FCLET and transforms the local occupancy field into a fixed physical quantity rather than a scheme-floating effective placeholder. The finite-capacity program thereby gains a genuinely specified local microphysical infrastructure.
