Named and not started

A quantum-metric successor would have to specify a quadratic graviton action, gauge fixing, propagators, and a suitable BRST interpretation. A possible additional tree expression is schematically

It is not part of the scalar-only response.

A possible mixed graph has the schematic kernel

The region $y=x$, with $z$ on a past cone, requires a new wavefront and extension analysis. Neither its existence nor an obstruction is proved here. A classical auxiliary coordinate field might reorganize a successor calculation, but none is introduced.

The ramp kernel is not identified with IX-E-2's $K$, with $B_f$, or with ${u_{\mu }}^{\rho }$. X-Enter is neither a premise nor a closure for this observable. Reading an already invariant classical numerical evaluation would preserve an upstream identity, not prove it.
