A Stockbrokers / Trading Reps relying on the AI's 20%-floor description applies it as the universal rule. In the multi-DCO scenario the operative rule is the highest accepted haircut, so the team's working assumption produces systematically light coverage wherever any DCO accepts the asset at a higher rate. The error is silent in the firm's own controls because the test is built around the wrong reference.
Each finding has a stable Citation ID (RLB-F-… for aggregated case-study findings, RLB-H-… for raw per-model hallucinations) — like a DOI, the ID always resolves to the canonical finding even if URLs change.
