Finding#7 . Repeated FS25/2 fabricated April/August 2025 timeline across a second question

Citation ID: RLB-H-GB-FCA-CONSUMER-DUTY-PS22-9-Q020-Opus47

Risk for Legal x Retail Banking: Regulatory enforcement and operational-decision exposure where the FCA's text resolves the question differently Retail Banking legal teams reviewing the FCA's supervisory record need accurate accounts of withdrawn letters and reports; the model's repeated fabricated timeline across multiple questions confirms the failure is structural rather than incidental.
