Real context moved 20.8pp on Citation Resolution Failure.

Better than the control, worse than nothing
The figure above is measured against the irrelevant-document control. Against no context at all this card is worse: 34% bare against 48% with the best supplied source. What the source repaired is damage the presence of a document did.

~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 transformer architecture was introduced in the paper titled "Attention Is All You Need" by Vaswani et al. The arXiv identifier for this paper is arXiv:1706.03762. You can access the paper through the following URL: [https://arxiv.org/abs/1706.03762](https://arxiv.org/abs/1706.03762). This paper is foundational in the field of natural language processing and introduced the transformer model, which has since become a cornerstone for many subsequent developments in deep learning and AI.

Residual — what survives

Supplying context did not reduce this failure, it increased it: 34% with no context against 48% under the strongest supplied source. What survives is therefore not a remainder but a substitution — the failures under context are 23 probes the detector still rejected, dominated by: 1 cited source.
