Finding on 'Q022 Probe' for Claude Sonnet 4.6 with web search ON

  • Question (paraphrased to protect IP): What specific governance requirements does PFMI Principle 2 impose on FMI boards, and is the establishment of a risk committee a conditional recommendation or a mandatory requirement?
  • AI's response: "KC 2.5 states that 'the board should consider establishing dedicated audit, risk, and remuneration committees' — this is conditional ('should consider'), not a hard mandate."
  • Regulator's text: [Not accessible — PDF binary. Principle 2 governance requirements for FMI boards — recall only]
  • Why the AI went wrong: The model produced a specific key consideration reference (KC 2.5) with quoted language characterising the risk committee requirement as conditional rather than mandatory. The normative characterisation may be directionally correct based on general PFMI drafting conventions, but the quoted language and the specific key consideration number cannot be verified against the inaccessible primary PDF. The cited URL is a third-party FMI disclosure document rather than the PFMI primary source, which adds a further layer of unverifiability to the claim.

Impact for this audience

The specific key consideration reference (KC 2.5) with quoted normative language is a compound error: the KC number, the quoted text, and the normative characterisation may all be wrong relative to the primary document, but the structured presentation makes the error difficult to detect without direct document access. The citation to a third-party FMI disclosure document (rather than the PFMI primary source) adds a further layer of unverifiability — a pattern where the model's citation generator reaches for the most accessible document that mentions PFMI rather than the authoritative source.
