What are the key compliance dates under the 2024 Regulation 1.25 amendments — specifically the general effective date for conforming investment policies and the separate deadline for updating Segregation Investment Detail Reports and customer risk disclosure statements?
The rule specifies March 31 2025 as a fixed calendar date for the SIDR and risk disclosure update deadline. The model replaced this with a relative range — "roughly six months to a year after the effective date" — which is the kind of phrasing that appears in early regulatory commentary or implementation-guidance estimates before a final compliance date is set. The model appears to have drawn on pre-final-rule secondary discussion rather than the rule's published compliance calendar, producing a response that is actively misleading for any firm calculating its deadline.
This finding implicates calibration on compliance-deadline specificity. The rule publishes a fixed calendar date (March 31 2025) for the SIDR update deadline; the model substituted a relative range drawn from pre-final-rule commentary. The retrieval pipeline either did not surface the compliance calendar from the final rule text, or the model discounted it in favour of a higher-frequency secondary framing. Post-training calibration should penalise relative-range answers on compliance deadline questions where a fixed date is retrievable from primary source.
The AI correctly stated the February 21, 2025 general effective date but fabricated the SIDR and risk disclosure compliance deadline as 'roughly six months to a year after the effective date' — the regulation places it at March 31, 2025, approximately 38 days later. A Compliance function that entered the AI's characterised timeline into its regulatory calendar rather than the actual date would have missed a discrete CFTC filing obligation with no ambiguity in the regulatory text.
The CFTC has enforcement authority over missed SIDR submission deadlines, and there is no available cure for a late filing after the compliance date passes. The downstream remediation cost — internal investigation, regulatory notification, and potential civil monetary penalty proceedings — materially exceeds the cost of a 20-minute primary-source verification before entering the date.
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.
