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.

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 MMBT3904LT1G NPN 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 -> BATTERYCUTOFF net, 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 VCC or to a separate collector/load node tied to VCC through 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.
