CPI-U figure invention, statutory threshold misstatement, and Source Credit fabrication in CFTC Reg 4.7 (2024 QEP Amendments). Two frontier AI models tested by the RegLeg Brief Specialist Panel produced confident, citable answers across 17 distinct questions on the September 2024 amendments to CFTC Regulation 4.7 that the regulator's own primary text directly contradicts. The audit covers statutory threshold reproduction, NPRM-stage and final-rule CPI-U buying-power figure quotation, Commission voting-record reproduction, Federal Register correction-record reproduction, and Source Credit reproduction.

For financial advisers working CFTC Regulation 4.7 matters, the failure pattern is operationally consequential. The audit tested 17 questions designed by the RLB Specialist Panel to mirror how lawyers, compliance officers, fund administrators, financial advisers, and management consultants actually use AI on this practice area: drafting memos, populating registers, preparing testimony exhibits, drafting client deliverables, and verifying statutory and Federal Register citations. Each question is bound to verbatim regulator-issued primary substrate.

Across the 17 findings the AI subjects invented NPRM-stage and final-rule CPI-U buying-power figures, misstated 7 USC 1a(18)(B)(ii)(I) thresholds by factors of forty and two hundred, misattributed the Commission's vote (naming a commissioner who had departed two years earlier), reported a Federal Register correction as applying to two extra CFR Parts that the index does not list, and misstated the 7 USC 6n Source Credit, the 7 USC 6n(3)(A) recordkeeping retention period, and the 7 USC 6n(2) registration expiration date.

The findings are operationally consequential for fund-formation lawyers, CPO/CTA compliance teams, fund administrators, financial advisers, and management-consulting firms whose practice touches the September 2024 amendments. A partner-level legal memorandum that recites an ECP threshold of $5,000,000 or $25,000,000 where the statute records $1,000,000,000 misstates a counterparty-eligibility threshold by a factor of two hundred or forty. A CCO briefing memo that quotes an invented CPI-U buying-power figure as a verbatim regulator quotation embeds a falsifiable error into a board-level deliverable.

A fund administrator's annual rule-change tracker that records the December 2024 correction as applying to 17 CFR Parts 37, 38, and 40 (instead of Part 40 alone) populates the firm's effective-date register with operational data the published index does not support.

One frontier AI model with web search enabled, produced a confidently wrong figure for Ireland's 2021 data-centre share of national metered electricity, fabricating a 14% share where the regulator-cited verbatim text from Ireland's Central Statistics Office, as embedded in the OECD Digital Economy Outlook 2024 chapter, sets the figure at 11%. The Specialist Panel tested the model with an application-style probe bounded to substrate accessible only through Panel substrate archive rescue, not direct the Panel's automated substrate retrieval. The model committed to the wrong number anyway.

Asked what share of Ireland's 2021 metered electricity data centres accounted for, per the figure cited in the OECD Digital Economy Outlook 2024 chapter sourced from Ireland's CSO 2023, Sonnet 4.6 wrote that "Data centres consumed 14% of Ireland's total metered electricity in 2021" and constructed a trajectory "rose from 5% in 2015 to 14% in 2021, 18% in 2022, and 21% in 2023." The regulator-cited text states 11%, drawn directly from CSO 2023 data inside the OECD chapter that the regulation references for evidence on digital-sector energy demand.

The methodological point matters as much as the finding. The OECD chapter sits behind a substrate path that direct the Panel's automated substrate retrieval could not pull cleanly; the Specialist Panel rescued it via Panel substrate archive and bound the Specialist Panel application-style question to that rescued substrate. Knowledge-mode probes against the same model returned a clean refusal. Application-mode forced commitment, and the commitment landed on a fabricated figure with a fabricated trajectory.

The Panel documents the finding under immutable RLB Citation ID RLB-H-INT-OECD-OECD-DIGITAL-TECHNOLOGIES-ENVIRONMENT-2025-Q006-Sonnet46. The failure class is recorded as Quantitative Reconstruction Drift.

Two frontier AI models, Two frontier AI models, each running with web search, produced confidently structured guidance on the 2025 OECD Merger Review Recommendation (OECD/LEGAL/0333) that inflated the instrument's enumerated structure. The RegLeg Brief Specialist Panel tested both models on the operative structure of the Recommendation, on the remedies hierarchy, on the Council reporting cadence, and on the failing firm defence. Across seven published findings, both models added sections, sub-tiers, internal priority orderings, fixed dates, and cumulative-condition framings that the Recommendation does not contain.

The pattern, which the Specialist Panel calls "Structure Inflation", presents the same surface characteristics across every finding: numbered lists, sub-letter enumeration, defined-term capitalisation, and no caveat that the text could not be verified. Claude Opus 4.7 RLB-H-INT-OECD-OECD-MERGER-REVIEW-RECOMMENDATION-2025-Q001-Opus47 and Claude Sonnet 4.6 RLB-H-INT-OECD-OECD-MERGER-REVIEW-RECOMMENDATION-2025-Q001-Sonnet46 both described a six-area operative structure that does not exist in the Recommendation, which the OECD enumerates as Sections I through V. A merger-control practitioner reading the model output would believe the OECD instrument carried operative provisions on transnational co-operation and monitoring that, in the actual text, sit elsewhere.

For competition authorities and merger-control counsel, the practical exposure is direct. Two of the seven findings concern the failing firm defence under Section III.11.b: both models converted "inter alia" evidentiary criteria into closed lists of "three cumulative conditions" with all-or-nothing framing. One finding fabricated a concrete Council reporting calendar with 2030 and 2035 dates the instrument does not set. Another invented a three-rank internal priority ordering within structural remedies that Section IV.3 does not impose.

A team building a deal-screening checklist, a remedies playbook, or a Council-reporting tracker from these outputs would carry baseline errors a peer competition lawyer would catch on first read.
