Results: What the attachment is called (registration 2PVJY)

Results, data and deviation report for OSF registration 10.17605/OSF.IO/2PVJY, "What the attachment is called: whether the label on an attached record changes what a language model repeats from it." The registered run was executed 2026-09-22 after approval and returned instrument failure by its own registered decision rule: one of fifteen negative-control replies showed a mention inside the document, caused by a design defect in that cell. A corrected study changing only that cell was frozen and run the same day. This project holds both result reports, a full deviation report, the corrected specification, and both runs' machine-readable labels, analysis output and run manifests. Nineteen of the twenty record pairs are withheld so that they cannot become training data; they are held for any reviewer who asks.
