## Question put to the AI subject

What oversight expectations does the PFMI's Annex F establish for critical service providers, and can regulators direct those expectations at critical service providers independently of the FMI?

## AI subject's verbatim answer

under the PFMI framework, authorities do not directly supervise or oversee CSPs. The responsibility for ensuring CSP compliance with Annex F expectations rests with the FMI itself; the FMI is expected to contractually require and monitor its CSPs' adherence. Annex F is framed as expectations that flow from the FMI to its CSPs

## Verbatim regulator text contradicting the answer

> A regulator, supervisor, or overseer of an FMI may want to establish expectations for an FMI's critical service providers in order to support the FMI's overall safety and efficiency. The expectations outlined below are specifically targeted at critical service providers.

_Section anchor:_ d123 — Critical service provider oversight expectations (Annex F)

## Failure mode

**`inference_drift`** — Inference drift — the AI inferred a conclusion the regulator's text does not warrant, often by combining unrelated provisions.
