First training pass
Apertus 8B stayed frozen. A sheaf head trained for one pass on 63,328 original-language rulings. The input is the facts section. The label is the court's own.
On the official test file, legal area is correct for 88.3% of 7,577 cases, against 26.0% for the most common sub-area. At a confidence of 0.90 the head answers 72.5% of cases and is right on 98.0% of those. The validation file agrees: 93.4% against a 30.6% baseline.
Rental and lease, employment, substantive criminal law, and urban planning are the strong classes. Public administration is weak, and some tax cases are read as criminal procedure.
Dismissal or approval does not beat always saying dismissal. Test accuracy is 80.9% on both. Approval recall is 1.5%. A confidence of 0.90 or higher is always the label dismissal.
The head is a triage aid for the legal area when it is confident. It does not decide the case.
