They also fine-tune a Gemma 3 12B detector on the high-confidence subset and report F1 0.729 on a held-out split. The structured supervision and the scale of real executions are the parts that stand out as new.\n\nThe soft spot is the labeling step itself. The 2,904 figure and the gap claim depend entirely on FullTax being accurate and consistent, yet the text supplies no annotation protocol, no inter-annotator agreement numbers, and no validation sample against human judgment or cross-model checks. With data drawn from only six source models, any systematic bias in how those models trigger the taxonomy would directly affect the reported gap. The detector result is on cleaner labels but does not test whether the labels capture genuine process issues.\n\nThis is for researchers building or monitoring deployed agents who want data for process-level supervision rather than outcome-only metrics.
