Saturated upper-profile budgets after the triadic grid maximum #

This module performs deterministic arithmetic on a proposed per-descendant saturated amplitude. If the ordinary lane on the strict descendant row m - 1 - k has scale

C * cstar⁻¹ * min 1 (gamma * (k + 1)) * 3^(gamma * (k + 1)),

then the Gamma_1 grid price contributes gridNetConst d 1 * (k + 1). Their product is exactly upperSaturatedProfile with a head whose grid multiplier is dimension-only and whose remaining dependence is C * cstar⁻¹ * 3^gamma. On gamma <= 1, the last factor is at most three.

The row index k corresponds to literal source depth r = k + 1, so the source strict-tail weight is geometricWeight s q (k + 1). The convenient k-weighted profile sum is a deliberate enlargement: it drops the additional one-step factor 3^(-s*q) but retains the source normalizer c_{s,q}. The depth-zero/root term r = 0 is separate and is not bounded here.

The analytic per-descendant estimate and the root estimate are not proved here.

The algebraic saturated scale assigned to strict-descendant row k. This definition does not assert an analytic estimate for that row.

        A plain factor gamma fits inside the saturated depth factor on 0 <= gamma <= 1.

        Consequently, an ordinary per-cube term carrying a bare gamma is dominated by the saturated target amplitude.

        Exact algebraic identity for the grid-priced row. This indexes the enlarged profile by k; literal source depth for the row is k + 1.

        On the standing small-gamma range, the exact grid-profile head is at most the enlargement retaining C * cstar⁻¹; only the grid multiplier is dimension-only.

        Advancing literal source depth by one extracts exactly one factor 3^(-s*q) from the geometric weight. The normalizer c_{s,q} remains on both sides.

        On 0 <= s*q, the literal strict-tail weight at source depth k+1 is at most the enlarged budget weight at index k.

        The normalized 1 <= q <= 2 aggregate of the k-weighted enlarged strict-tail budget has the cubic pole. This theorem is about the displayed enlargement, not the literal source-depth carrier.
