We construct the microphysical closure of the finite-capacity latency–erasure theory by deriving the local information-capacity variables that underlie the latency field . Earlier FCLET papers established the canonical burden map, the normalized occupancy variable , and the emergent latency relation , and showed that this structure generates coherent weak-field, cosmological, stochastic, thermodynamic, strong-field, galactic, and quantum-sector descendants. What remained open was the microphysical definition of the local information content itself. The present paper closes that gap. We define a local causal patch, identify its admissible microphysical degrees of freedom, and construct the effective local information content from coarse-grained entanglement entropy within that patch. We then define the maximal local information capacity through the geometric entropy bound appropriate to the same causal domain, and obtain the normalized local occupancy field This yields the FCLET latency field as a derived microphysical variable, rather than as a merely phenomenological placeholder. We show that the resulting construction is dimensionless, bounded, patch-local, and compatible with the recovery structure already established across the theory. The weak-load regime reproduces the previously used linearized branch, while the high-load regime generates the nonlinear saturation architecture required by the compact-object and cosmological sectors. We further analyze renormalization, cutoff dependence, species counting, and covariance conditions for the local patch entropy, and show how the entanglement-based definition of yields a finite-capacity occupancy field that can be carried consistently into the effective FCLET equations. The paper therefore provides the missing microphysical foundation of the theory: the local burden variable is no longer introduced axiomatically, but derived from the ratio between realized local information content and geometrically admissible local information capacity. This result is structurally decisive. With the microphysical definition of , , and now in place, the FCLET program gains a fully articulated local substrate basis linking causal patches, entropy bounds, finite information capacity, and emergent latency physics.
