Release and scope

and scope{ Constructed: exact network-support and physical-containment theorems; operational signalling criteria; localization and clock contracts; periodic directional bounds; robust finite-time margins; approximate signalling and simulation estimates; and a buffered causal realization through VII-F's event.

Two targets remain distinct. Target A concerns the complete decoded simulation channel. Target B additionally embeds the actual elementary communication and gates in the supplied causal geometry.

Explicit model boundary. The cone application is a finite carrier-and-controller model on a prescribed metric cone. It does not derive matter propagation from Einstein dynamics or provide a continuum-field simulation.

No compilation, numerical execution, experimental implementation, or machine verification is asserted.}
