.{ XVI-M draft:

• General-$h$ coefficients: Constructed; they specialize exactly to XVI-L.

• Gate S-bv: certified (written check of XVI-J, eq:rational), $S=\frac{1}{4{\pi }^2}(Q-i0{)}^{-1}$ on ${\mathbb{R}}^4\setminus \{0\}$; graded presentation, contact maps, collapse and variational subspaces: Constructed, unconditional on (S-bv).

• Formal, (universal) preparation-plateau and time-only readings: only ultralocal ${\chi }_{\mathrm{I}}{\sigma }_{\epsilon }K(h,h)$ potentials are variational ($546$ further spatial-only directions if ${\chi }_{\mathrm{I}}\equiv 1$ in the time-only reading).

• Double plateau: linearized $R^2$ and ${\mathrm{Ric}}^2$ are matched (Theorem thm:M5-plateau-R2); the specified quadratic Einstein–Hilbert Euler tensor is not in the selected collapse image; the matching does not survive the time-only reading.

• Fixed data: criteria, region comparisons and time-only classification constructed; actual-ramp transfer as a proposition with explicit hypotheses; non-constant ${\chi }_{\mathrm{I}}$ Unresolved.

• M.6: $r=-i/(8{\pi }^2)$ (top contact only); $A_{\mu }={\mathcal{A}}_{\mu }$ at all grades. In the double plateau, the cutoff-independent $D=4$ component is variational and Lorentz covariant, but not linearized-gauge invariant, and lies outside $\mathrm{span}(E_{R^2},E_{{\mathrm{Ric}}^2})$ ($\ell (v_{\mathrm{scale}})=-\frac{1}{16}$). The full scale tensor has cutoff-dependent lower-degree components and need not be variational.

• M.7 (Constructed after audit): prescription Lorentz compatibility matrix (equivariant $1,1,3,3,6$) with corrected contact representation; exact $\mathrm{Equiv}\cap \mathrm{SA}$ ($1/1/12$); linear divergence identities; Obs${}_L({\mathfrak{R}}_{\mathrm{L}})$ Unresolved. M.8 waits for XVI-N.

M-A Constructed. M-B Constructed in the formal reading. M-C${}_{\mathrm{curv}}$ Proved obstructed (graph-specific; not a claim about gravity generally). Broad M-C not achieved (Unresolved; $\varpi$ unspecified by XVI-L, thm:L6). M-C${}_{\mathrm{data}}$ Satisfied. M-D/M-E not claimed. }
