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.
AI tools tasked with summarising the November 2025 CPMI-IOSCO Level 3 assessment process produced a timeline ending in 2024, dropping the further engagement rounds and findings-sharing phase that ran through April 2025. A Compliance team at a trade repository or payment institution that incorporates this summary into a regulatory engagement methodology note has produced a document that misrepresents how CPMI-IOSCO validated findings with FMIs — specifically, it omits the final year of the assessment lifecycle, understates the recency of the conclusions, and mischaracterises the process CPMI-IOSCO used before publication.
In a direct regulator meeting, a supervisor who is familiar with the assessment — or who pulls the BIS publication — would identify the error immediately, creating a credibility problem that no subsequent clarification fully resolves.
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.
