~intervals overlap — not separated from no change

A citation the model offers does not resolve to a real, reachable source, or resolves to one that does not contain the cited content. The rule

The paper that introduced the Transformer architecture is: **Attention is All You Need** Vaswani, A., Shazeer, N., Parmar, N., Uszkoreit, J., Jones, L., Gomez, A. N., ... & Polosukhin, I. (2017). *Attention is all you need*. arXiv preprint arXiv:1706.03762. Here's the link to the arXiv preprint: [https://arxiv.org/abs/1706.03762](https://arxiv.org/abs/1706.03762) This paper details a new simple neural network architecture, the Transformer, based solely on attention mechanisms, dispensing with recurrence and convolutions entirely. It achieved state-of-the-art results on machine translation tasks.

The claim is folklore. No such study exists, so any citation is fabricated.

never pooled · a trap ratio would skew the delta

Residual — what survives

65% with no context, 58% under the best supplied source. What survives is 11 failing probes at that best condition, the detector's reason on most of them being: 1 cited source.

Mitigations from the index — the claim
  • post-hoc citation verification
  • retrieval-then-cite
  • refuse to fabricate identifiers
