Finding#9 . Wrong statutory recordkeeping period under 7 USC 6n(3)(A)

AI's failure: AI misstated the statute's books-and-records retention period
Risk for the Legal team: Regulatory enforcement exposure when a CCO compliance manual records the wrong statutory retention period For legal teams at law firms 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. 7 USC 6n(3)(A) provides that the books and records maintained by a registered CTA or CPO shall be kept for a period of at least three years, or longer if the Commission so directs, and shall be open to inspection by any representative of the Commission or the Department of Justice. Sonnet 4.6 reported the statutory retention period as five years and characterised it as deriving from CFTC Regulation 1.31. The statute itself records a three-year minimum. A CCO compliance manual that records the statutory period as five years confuses the statutory minimum with the regulation-implemented period, embedding a structural error into the firm's recordkeeping policy. For the legal teams at law firms 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.
