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 Compliance team at a Management & Risk Consulting firm uses AI to draft a methodology note on the CPMI-IOSCO Level 3 general business risk assessment, AI assistants we tested stated the assessment ran through 2024 — omitting the April 2025 findings-sharing phase documented in the primary report. A methodology note carrying that error, incorporated into a client's regulatory engagement summary, misrepresents to the client's regulator when the CPMI-IOSCO process formally concluded and how findings were validated with participating FMIs.
The consulting firm owns the factual inaccuracy in the delivered work product, and remediation requires a corrected submission, client notification, and an account of how the error entered the document — a sequence that surfaces in client relationship reviews and, where the firm operates under regulated advisory obligations, potentially in its own compliance record.
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.
