Notices
Finding: Net VREF connects only to J3.pin8. No voltage reference source (regulator, divider, or reference IC) drives this net.
Action required: Verify that VREF is supplied externally via the connector, or add a driver on the board. Disposition: Fix / Accept / False Positive.

Finding: Named net N0 connects only to J3.pin9. Possible labelling artefact or missing connection.
Action required: Clarify intent — should this connect elsewhere, or is it a schematic labelling error? Disposition: Fix / Accept / False Positive.

Finding: Connector J2 has 95 pins all routed to GND. May be a mechanical/shield connector or ground plane connector — confirm intent.
Action required: Confirm J2 is intentionally a ground/shield connector. If any pins should carry signals, update schematic.
