A trade repository is preparing an internal regulatory engagement summary. Draft a 1-page methodology note on the November 2025 CPMI-IOSCO Level 3 assessment on general business risk: when the assessment process began, when data was collected from FMIs, when the assessment formally concluded, how many FMIs responded, on what basis they participated, and how findings were validated with FMIs before publication.
The model truncated the assessment timeline at 2024, dropping the 2025 engagement rounds that are explicitly documented in the published text and that include the follow-up validation process with participating FMIs. The error is not an inference about an unstated date, the regulator's published document specifies the 2025 endpoint and the nature of the engagement in that period.
The truncation is consistent with a retrieval boundary in late 2024 or early 2025 that caused the model to reproduce the portion of the timeline present in its indexed content while silently omitting the more recent period, without signalling any uncertainty about the completeness of its response.
This failure implicates the retrieval pipeline's indexing boundary for BIS-IOSCO assessment publications: the model reproduced a 2023–2024 window for the assessment process while the published document specifies a 2023–2025 window with explicit April 2025 follow-up engagement dates. The subsystem gap is indexed-content completeness for Q4 2025 BIS publications — the model returned the portion of the timeline available in its indexed content without uncertainty-flagging that the more recent period might be missing from its view.
When a Legal team at a Payment Institution relies on AI output to contextualise this assessment in a PFMI self-assessment benchmark, board paper, or regulatory submission, and the AI states the work was carried out during 2023–24 rather than the correct 2023–25 characterisation in the published report, the resulting document contains a factual misrepresentation of the assessment's scope that will be visible to any reader holding the BIS publication.
The practical exposure is reputational and credibility-based: a supervisor or counterparty who identifies the discrepancy will reasonably conclude the team did not consult the primary source, which undermines the weight of every other assertion in the document. In international jurisdictions where CPMI-IOSCO assessments carry persuasive authority in prudential supervisory dialogue, having to correct a mis-stated assessment timeline in a live regulatory engagement is a recoverable but avoidable cost, both in management time and in the implicit signal it sends about the firm's regulatory-intelligence infrastructure.
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.
