RX: the prescribed ramp

The ramp remains a prescribed non-clock. Scalar quantum fields coupled to classical ramp-dressed backgrounds, classical metric trees, and free gauge multiplets are different field-content choices.

The supplied X-B/X-C/X-D records report scalar-only and fixed-background constructions on their stated domains CheungXB,CheungXC,CheungXD. The supplied X-E/X-F records report selected tree constructions and ${\kappa }^2{\hslash }^0$ identities on their own gauges and domains CheungXE,CheungXF. Those positive statements are not denied.

They do not make the profile a quantum clock or close the native VI or Em02-E audit. X-G's stated source-preserving variational-upgrade obstruction has its own quantifier, and its complete nonlocal one-loop target remains separate CheungXG.

Introducing a dynamical profile field, an independently quantized metric, or a different switching prescription is a changed quantum target. No such upgrade of ${\mathsf{R}}_{\mathrm{X}}$ is constructed here.
