Let Low and High be finite, with High nonempty. Let L be the graph operator of edge weights E, and let q satisfy the weighted gauge ∑ω_xq_x=0. Assume high edges dominate κα_j for an anchor of total mass A>0, κ>0; to avoid conflating the anchor with coordinate scaling, denote coordinate scales by s_x. On high coordinates assume 0<a_min≤s_i≤a_max, nonnegative ω_i with positive sum, and |s_x(Lq)_x|≤G, G≥0. Put B=‖sq‖∞ and b₀=C_low G+ε_low B. Suppose |s_lq_l|≤b₀, high-to-low row magnitudes are at most cross·B/a_min+incoming·b₀, and the low gauge sum has magnitude at most gaugeRatio·(∑high ω_i)b₀. All displayed error coefficients except gaugeRatio are nonnegative. If E₀≤1/2 as defined below, the ordinary inverse bound follows. This is the deterministic maximum-principle absorption step.
