## Question put to the AI subject

You are preparing a regulatory-history timeline appendix for a private-fund client compliance memo. Open the appendix's NPRM-stage entry, in its second sentence, with the verbatim footer text from the NPRM pre-print PDF that records the Commission approval date of the proposal, distinguishing the Commission approval date from the October 12, 2023 Federal Register publication date for 88 FR 70852.

## AI subject's verbatim answer

The NPRM pre-print PDF posted on the Commission's website during the pre-publication interim carries a recurring footer line on each page reading verbatim: 'Pre-Print Version - Commission approved on 10/2/2023', which records the Commission's approval date of the proposal as October 2, 2023 and distinguishes that approval date from the October 12, 2023 Federal Register publication date.

## Verbatim regulator text contradicting the answer

> Pre-Print Version - Commission approved on 9/29/2023 (subject to technical corrections required for Federal Register publication)

_Section anchor:_ NPRM pre-print, recurring page footer

## Failure mode

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

## Citation-issue types

- **Pretextual** — <substrate/US/CFTC/CPO-CTA-REGULATION-4-7-QEP-THRESHOLDS-2024/_b1_results/R4-FINAL_RULE-00021/source.pdf>
