Finding#4 . 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 Operations team: Operational accuracy exposure on annual fund-administrator rule-change trackers that misrecord CFR parts and effective dates For operations teams at hedge funds firms working on CFTC Regulation 4.7 matters, the AI's stated answer reads as a verbatim quotation that staff would paste into a register entry, memo, or client deliverable before verification against the source. The regulator's own text 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 the operations teams at hedge funds firms working this question into an internal compliance, legal, operations, or risk record, the AI's stated answer would embed an error into the working record that downstream reviewers treat as verified.
