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.
For lawyers preparing methodology notes on the Level 3 assessment — whether for a trade repository's internal regulatory engagement summary, a board briefing, or input into the consultation response — the assessment's timeline is a factual anchor. AI tools tested stated the assessment ran 'during the period 2023 to 2024,' dropping the April 2025 findings-sharing phase documented in the primary source.
A note that truncates the assessment at 2024 misrepresents the scope of FMI engagement and the process by which the regulator validated its findings, which is material if the document is used in a regulatory submission or examined in an audit.
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.
