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.

Project Specification — NF-Universal Alarm
Purpose
Create a best-effort Flux schematic from the uploaded GZ-TU-REV2_sch.png reference image for the NF-UNIVERSAL ALARM circuit.

Reconstruction policy
Use exact visible designators where readable. Use common Flux library parts for U1, U2, U3, Q1, and Q2 where the image is unclear. Use generic passives with the visible values and add notes where confidence is limited.
Verification notes
This schematic is image-derived and must be checked against the original CAD/BOM before fabrication.
