How does Burna AI compute attribution?

Attribution uses two named causality algorithms with visible math: the WHO-UMC (World Health Organization-Uppsala Monitoring Centre) classification and the Kramer algorithm. The engine produces per-drug probability scores (certain, probable, possible, unlikely, conditional, unassessable for WHO-UMC; and a multi-dimensional score for Kramer). The math is shown, not hidden. This is the opposite of a black box. The clinician reviews and decides; the architecture preserves the reasoning.
