and novelty. The particle family and the principal source distinctions are adapted from the version-3 VIII records. The contribution of this manuscript is their supported $3+1$-dimensional product assembly, explicit fixed-host interpretation, complete clock interface, finite-promise safeguard, and regular causal transport. The source's separate particle-free four-face substrate is not silently identified with the particle profile used here.
