Finding#2, KC3 six-month LNAFE minimum, misattributed to KC2

AI's failure:Exposed Fabrication Risk for Lawyers:Wrong deliverable
What the RLB Specialist Panel found
For Claude Opus 4.7 (web search on)
Question (paraphrased to protect IP)

A head of liquidity risk at a major derivatives CCP wants a briefing covering the PFMI Principle 15 requirements for liquid net assets funded by equity, the minimum level, how it is calculated, and what qualifies, together with what the November 2025 CPMI-IOSCO assessment found about FMI compliance with this standard, and what changes the FIA and ISDA proposed in their response to the associated CPMI-IOSCO consultation.

RLB's analysis

The model located the correct quantitative threshold but attributed it to Key Consideration 2 instead of Key Consideration 3. The error is a cross-reference mis-assignment, the model's description of KC2's function ("potential general business losses") is drawn from the correct Key Consideration, but when it located the six-month floor it attached it to the wrong KC number. For a compliance team using this response to draft internal policy, the mis-assignment directs them to review and cite the wrong provision of the PFMI framework, with material consequences for regulatory engagement accuracy.

The model also cited a third-party regulatory commentary source as a basis for this section of its response.

AI Head's analysis — what weakness in the AI model caused this

This failure implicates the model's cross-reference resolution within the PFMI Principle 15 Key Consideration list: the correct threshold was located but attributed to KC2 instead of KC3. The subsystem gap is structured-document KC-number-to-provision linkage in training data — the model's Annex A representation does not reliably bind specific quantitative requirements to their correct KC identifier. The Pretextual citation (third-party commentary) used as a sourcing basis for this section of the response compounds the error.

Impact for Lawyers in international jurisdictions advising on the Implementation Monitoring of the PFMI: Level 3 Assessment on General Business Risks

The six-month LNAFE floor is in KC3. AI tools we tested placed it in KC2, and maintained that position even when challenged. For a lawyer advising a derivatives CCP, that KC mis-attribution is not a labelling error: KC2 and KC3 carry different conditions and different governance implications. A briefing to a head of liquidity risk that cites the wrong KC will be immediately visible as incorrect to the risk function and the regulator, undermining the credibility of the advice and requiring correction before it can be relied upon.
