Complete schedule locality

This is the complete-channel argument of the schedule comparisons CheungEn03,CheungEn05. It does not concern selectively normalized postselection maps or unpriced access to remote records.

The fixed-time current and its surface support lie in $K_f$, so their admitted geometric evaluations remain in the prescribed past shadow. This statement is distinct from the global Newton-data dependence of Section sec:cubic.
