Updated 26 top-layer pads connected to the GND net to use
thermalRelief = Relief connect. Verified the updated GND pads now compute as thermalReliefType: Relief connect; component placement, routing, and net connectivity were not changed. DRC still reports existing dangling/floating/overlapping copper issues, but no new thermal-relief-specific issue was reported.List DRC issues

Q1 MOSFET Replacement Notes
Summary
Q1 was replaced with a BSS138 N-channel MOSFET placeholder to preserve the intended BATTERYCUTOFF switching role from the image-derived schematic.
Original BJT mapping assumption
- Original Q1 was
MMBT3904LT1GNPN BJT. - Original/approved functional mapping from the BATTERYCUTOFF circuit:
- BJT Base -> MOSFET Gate
- BJT Emitter -> MOSFET Source
- BJT Collector -> MOSFET Drain
Implemented MOSFET connectivity
Q1:G->BATTERYCUTOFFnet, shared with the S1/R8 side of the cutoff control network.Q1:S->GND.Q1:D->VCC, representing the collector/R8/VCC side requested in the replacement plan.
Uncertainties to review before production
- The source schematic image was blurry and image-derived; confirm whether Q1 should be an N-channel MOSFET.
- Confirm whether a BSS138-class MOSFET is electrically appropriate for the actual load/current.
- Confirm physical pin mapping, footprint orientation, and symbol orientation for the selected MOSFET.
- Confirm whether the drain should connect directly to
VCCor to a separate collector/load node tied toVCCthrough R8 in the original CAD.
Production recommendation
Treat Q1 as a placeholder until the original BOM, clearer schematic, or designer intent confirms the exact MOSFET MPN, pinout, and orientation.
