Principal correction: catalogue replacement is not metric evolution

correction: catalogue replacement is not metric evolution{ The operational background is fixed throughout each experiment. A register may store a description of another prescribed cone. Replacing that register does not replace the metric under the apparatus. When the selected deficit differs from the host deficit, its matching certificate concerns the selected catalogue member, not an asserted new geometry of the laboratory.

Similarly, a finite computation describing the transverse incidence does not cause the incidence or measure the singular worldsheet. All quantum registers and operational routes below remain in the regular part.}
