The oscillation half of the cutoff-mean row for the adjoint sign #

This file proves, for the adjoint recentred coefficient a_+ = a^T + g, the same closing statement proved elsewhere for the negative sign: the oscillation half of the cutoff-mean row is bounded by the source load once the terminal optimizer family supplies the refinement identity at every depth, the cutoff-weight increment, and the pathwise crossed-pairing bound on each descendant cell. Only the sign of the recentred coefficient changes; the increment envelope, the vanishing remainder, and the general closure statement are shared with the negative-sign case and are not reproved here. The per-descendant-cell crossed-pairing bound is again left as a hypothesis, to be discharged where the terminal optimizer field for this sign is actually constructed. The bound is the adjoint-sign half of the cutoff-mean row used by the cutoff estimate p.response.transfer, and so contributes to the polynomial entry result t.polynomial.entry.

The oscillation half of the cutoff-mean row at the carriers, adjoint sign #

The adjoint twin of CutoffOscillationHalfClosure: the same carrier data for the recentred adjoint coefficient a_+ = aᵀ + g, with the same per-descendant-cell crossed pairing left as a hypothesis.

The oscillation half of the cutoff-mean row at the carriers, plus sign. The (φ-1)-weighted cell average of the crossed pairing of the deterministic dual variable with the terminal optimizer state is P-integrable, and its annealed mean differs from that of its depth-H cell part by at most 32 d² Θ 3^{-H} (3^{3/2} 𝓛_s^-)^{1/2} (8 E[J_t^-])^{1/2} times the geometric factor.
