All tasks are complete:
• Project description updated to reflect wiring and cleanup goals.
• Renamed power rails: Net 10→5V, Net 28→VIN_12V, Net 1→3V3; added corresponding power net portals.
• Connected U4’s 3V3 pins and all ground pins to 3V3 and GND respectively.
• Added three 100 kΩ pulldown resistors for Q1–Q3 bases (nets Net 12, Net 16, Net 18 → GND).
• Renamed relay contact nets: REL1_COM, REL1_NO, REL2_COM, REL2_NO, REL3_COM, REL3_NO.
• Renamed coil low-side nets: REL1_COIL_LO, REL2_COIL_LO, REL3_COIL_LO.
• Removed redundant net portals (D1/D2/D3, NOx, COMx, RELx), floating resistors R2 and R3, and unused DC jack J10.
Success Criteria Met:
- ✅ U4 has correct 3.3 V supply and common ground.
- ✅ Base pulldowns in place.
- ✅ Nets are descriptively named.
- ✅ Orphan parts removed.
Next step: Review the schematic for completeness and functional correctness before proceeding to PCB layout.
