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.++## Clip 12: silkscreen on real geometry, then the 3D board++::adom-video{src="/adom/antigravity/render/first-ai-pcb/videos/clip12.video.json"}++Argon's first silkscreen audit passed on made-up geometry: every part a 0.4 mm square and every label a 0.6 mm square, so nothing could collide. We sent it back. It measured every pad, via and label from the board, moved the labels that really overlapped and passed with 38 visible labels on 33 parts. Then the 3D walkthrough in KiCad: the TPS54202 and the AMPLH5030S inductor carry their part numbers, and the back of the board names the circuit, 12 V to 5 V at 1 A. Length 31 s.
