Argon widened that copper in KiCad through kicad-bridge, saved the board and solved again: the peak fell to 32.0 A/mm², every loaded net passes, and the hottest rise is 48.1 °C against a 50 °C budget. Length 31 s.++## Clip 11: thermal, fixed with copper and not a new budget++::adom-video{src="/adom/antigravity/render/first-ai-pcb/videos/clip11.video.json"}++With Adom Fields the current check passed on every power net (peak 35 A/mm², limit 60). Thermal did not: the inductor L1 sat on a 4 mm² patch of switch-node copper, about 53 °C over ambient against a 50 °C budget. Argon's first move was to book that heat onto the bigger output pour in the spec; we sent it back to fix the board instead. It poured the switch node on both layers (65 mm²) and stitched them with 16 vias at the inductor pad: the estimated rise fell to 26 °C, and the regulator sits at 9 °C. Length 32 s.
