Done — I connected the schematic ground-related pins to the common GND net.
Connected to GND now:
  • J1:2
  • J2:2
  • U1:GND
  • U2:GND
  • C1:P2, C2:P2, C3:P2, C4:P2
  • R2:P1
  • D1:A
  • U1 unused inputs: 3A, 4A, 5A, 6A
  • TP4 ground test point
I also verified the GND net afterward; it now includes the expected connector, regulator, logic IC, capacitor, pull-down, diode, and unused-input ground connections.
Connect all grounds
Use common GND
Run ERC after
Handle shield grounds
