This upload presents a contract-grade re-expression of a scattering-theory explanation for chirality-driven anomalous Hall effect (AHE) sign reversal in highly conductive metals, targeting the specific claim that nonmonotonic temperature dependence and outright sign flips can occur even in a regime dominated by skew scattering; the source mechanism is treated as valid physics input, but the contribution here is operational: it freezes sign, null, and decomposition into an auditable G–Sigma–P–L corridor so a “sign flip” cannot be created by lane relabeling, regime swapping, smoothing, or incomplete reporting, and it makes the short-range vs long-range correlation competition (and the high-field correlation sign-change regime) explicit as named lanes with required witnesses; it also separates node-driven reversals (Bessel-node geometry in kF a and distance classes) from correlation-driven reversals (correlation proxy changes sign), defines a minimal numeric disclosure set that avoids raw-trace demands while still preventing “partial-numbers” narrative abuse, and supplies a falsifier kit (data sufficiency gate, flip-only node motion test, correlation-sign witness, ledger consistency, window subdivision invariance, and leave-one-out 3-of-4 decide with a 4th auditor) so the story can fail cleanly; optional labels (Strong vs Strong-to-Weak) and an optional Ternary Knob stress wrapper are permitted only under zeros-stay-zeros and SoZ/yield discipline to prevent knobs from becoming postselection controls.
