Archetype Sub-90 Dry-Wipe Invariant (Quadratic Discriminant (b^2 - 4ac), Root-Difference Identities & Parameter Range Inequalities): For ax² + bx + c = 0, the positive difference between roots is ALWAYS |alpha - beta| = sqrt(b² - 4ac) / |a|. For two distinct positive roots, intersect three conditions: Δ > 0, -b/a > 0, and c/a > 0.
