Release and proof boundary

and proof boundary{ Constructed: the prescribed classical response, its completed compact root, the compact microcausal cubic kernel, carrier admission, ordering transport on the enlarged named sector, and the exact signed plateau variation.

Corrections: a compact root generally requires an ambient time collar; its effective source-weighted coefficients, not the raw transposed root, have nonnegative-time support. The prescribed positive-source forcing response has a negative two-jet variation. A positive two-jet law would belong to the opposite forcing sign.

Not claimed: unqualified plateau invariance of ${\mathcal{C}}_{3,\mathrm{D}}$ alone, construction of the complete second-order relational observable, or repair of the invariant coupled jet.

The original detected unramped classes remain excluded. No carrier enlargement, quantum retarded product, state, loop, interacting differential, or $\epsilon \to 0$ limit is opened.}
