Falls whenAn error localisation on a commercial deep-research product that places most unsupported citations at retrieval; or a depth ablation on further models that shows no decline. Query: repeat of the tool-call ablation of arXiv 2605.06635 on a third and fourth model.
Conclusion
Per-citation support fell from 78.6 to 16.7 percent (GPT-5.4) and from 80.0 to 57.9 percent (Claude Opus 4.6) as the tool-call budget rose from 2 to 150, and in three open multi-agent pipelines the orchestrating step was the origin of 52.6 to 100 percent of traced final-report errors while the searcher accounted for 0.4 percent in the one system where it is printed. Both point to synthesis over many sources, not retrieval, as the place where support is lost.
Step
The ablation contributes the dose-response: more tool calls, lower support, link validity and relevance above 92 percent at every depth. The localisation study contributes where errors are introduced, in different (open-source) systems. The step joins two systems classes under the premise that commercial agents fail in the same place as open pipelines; that premise is not measured in either parent. The GPT-5.4 series is not monotone, so the conclusion is about the end points.
Breaking point
An error localisation on a commercial deep-research product that places most unsupported citations at retrieval; or a depth ablation on further models that shows no decline. Query: repeat of the tool-call ablation of arXiv 2605.06635 on a third and fourth model.
Reflex
More searching means better-grounded answers. In the one ablation that varied it, support fell with search depth.
Notes
Attacker run 3 (attacker-grok-4.7, x-attack-step): refused on the main point, the joining premise is declared in the step and named in the breaking point, not hidden; 'unchanged' corrected in place to 'above 92 percent at every depth'.

The ablation parent shows Fact Check falling between the endpoints while Link Works and Relevant Content stay above 92%, not that they are unchanged, and the localisation parent places the orchestrator as the origin of errors only in three open pipelines. Stronger: parent stocks/ai-citations--raising-tool-calls-from-2-to-150-drops-fact-check-from-79-to-17-percent-for-gpt-54-and-from-80-to-58-for-claude-opus-46 supports a drop with tool-call budget for two commercial models while links keep resolving, and parent stocks/ai-citations--orchestrator-originates-85-percent-of-final-report-errors-in-ai-q-53-percent-in-ms-agent-and-100-in-trajectorykit does not measure those models, so the premise that they fail at the orchestrator is in neither parent.
