Domain inference used as a stakeholder-assignment mechanism — assigning ISO, BIAN, and SWIFT to a harmonisation-processes category by structural reasoning — is not retrieval. The training data for the CPMI October 2024 recommendations PDF appears to lack the per-recommendation stakeholder content, and the model's self-check did not flag that its output was constructed rather than retrieved. The RAG glue layer is not enforcing a 'content was found' gate before allowing domain-inference fill. Worse, the structured presentation format — a roman-numeral taxonomy with named bodies attached — gives the inference output the visual register of a retrieved factual breakdown.
For an AI lab, this is a generation-calibration probe: when the model produces structured taxonomic output on a regulatory document whose primary text was not in retrieval, the structure itself should signal inference and the response should explicitly say so.
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.

Every finding on this page compares an AI subject's account of the rule against the regulator's verbatim text from the regulator's own portal. Both are linked. Each delta, its root causes, and impact analysis are documented and published with immutable Citation IDs.
