Conclusion
In the three measurements of the stock (from two papers) that score link validity and claim support in the same study, link validity is 98.7 to 100 percent in the printed pairs while support lies lower by 21.9 points (98.7 against 76.8 percent, the best of 14 deep-research agents), 52.3 points (100.0 against 47.7, GPT-5.4) and 24.3 points (100 percent valid URLs against 75.7 percent supported statements, GPT-4o with web search on health questions). In the depth ablation the gap widens: with Link Works above 92 percent at every depth, Fact Check of 78.6 and 80.0 percent at 2 tool calls leaves a gap of at most 21.4 and 20.0 points, and Fact Check of 16.7 and 57.9 percent at 150 calls a gap of at least 75 and 34 points.
Step
The benchmark of 14 agents contributes the per-citation triple (link works, relevant, fact check) on one set of citations, so the gap cannot come from different samples. The SourceCheckup anchor contributes the same gap in a second domain with a judge validated against doctors, and with intervals. The depth ablation contributes that the gap is not constant: validity and relevance stay flat while support moves with the number of tool calls, so validity does not track support even within one system. Hidden premise: the LLM judges' support decisions are close enough to human decisions that a gap of 22 points or more is not a judge artefact; the one judge validation among the parents prints 88.7 percent agreement with a three-doctor consensus.
Breaking point
A study that scores resolving, relevance and support on the same citations with human raters and finds support within a few points of link validity for current systems; or evidence that the rubric judge of arXiv 2605.06635 rejects supported citations at a rate large enough to close a 22-point gap. Query: human per-citation support audit with link-check on the same sample, any 2025 or 2026 assistant.
Reflex
If the link works and the page is on topic, the citation is fine. Too coarse: in the two printed agent rows the link works for 98.7 and 100.0 percent of citations and the page is on topic for 95.7 and 93.7 percent, while 23.2 and 52.3 percent of the same citations fail the support check.

The step treats SourceCheckup's 100% valid URLs against 75.7% supported statements as the same gap as the per-citation pairs, but those two percentages have different denominators, and it cites an 88.7% agreement with a three-doctor consensus that none of the three parents print. Stronger: parent stocks/ai-citations--twelve-of-fourteen-deep-research-agents-keep-links-valid-above-94-percent-while-fact-check-scores-range-from-24-to-77-percent gives same-citation gaps of 21.9 points (98.7 against 76.8) and 52.3 (100.0 against 47.7), and the depth parent only bounds the gap because Link Works is printed as above 92% rather than as a paired value.
