Finding#16 . Wrong CFR Parts on the 89 FR 96897 correction index record

Citation ID: RLB-H-US-CFTC-CPO-CTA-REGULATION-4-7-QEP-THRESHOLDS-2024-Q031-Opus47
AI's failure: AI misstated the CFR Parts affected by the 89 FR 96897 correction and the effective date
Risk for the Lawyers: Operational accuracy exposure on annual fund-administrator rule-change trackers that misrecord CFR parts and effective dates For lawyers working on CFTC Regulation 4.7 matters, the AI's stated answer reads as a verbatim quotation that a practitioner would paste into a memo, register entry, or client deliverable before verification against the source. The regulator's own text, however, records a different position. The CFTC Final Rules 2024 index page records the 89 FR 96897 entry as: 12/6/2024 89 FR 96897 17 CFR Part 40 Provisions Common to Registered Entities; Correction. Effective Date: Monday, December 9, 2024. Opus 4.7 reported the affected CFR Parts as 17 CFR Parts 37, 38, and 40 and the effective date as 12/6/2024 (treating the publication date as the effective date). Both the CFR-Part list and the effective date are incorrect. A fund administrator's annual rule-change tracker that records this entry as the AI states will misalign the firm's effective-date file by three days and overstate the CFR-Part scope by two parts. For a lawyer drafting on this question, the immediate risk is that the AI's answer enters a client memo, board briefing, or transactional opinion without verification, and that the inconsistency surfaces later under counterparty review, regulatory inquiry, or internal QC.
