Published mechanical/side-fan-r1: fan 16 mm outside PCB, reinforced connected carrier with through-bolted clamps and 6 mm gussets, nominal ATS 50 x 50 x 25 mm sink with insulated Q1 contact. Geometry screening has no unexpected component-body intersections; carrier is one valid solid. New cooling path reopens thermal acceptance; physical strength, retention, airflow and full probe sequence validation remain open. Board32 and native PCB unchanged. Separate probing-preview-sidefan study reports 14 existing measurement entries and five entries relying on three proposed pads (not fabricated/routed). Three-pad routing/native DRC and complete plan/collision checks remain required. README, hero and three-page datasheet updated. Clean 30.27 s native CAD review clip retained; first overlapping-model take rejected.+++### Overnight continuation — 13 October 2026++User explicitly requested continuing until the board is finished. AIFlow returned to routing. The side-fan redesign proposal failed native copper/courtyard checks; it is rejected pending correction. Earlier routed DFT candidate plus a GND stitch at (142.85,71.76), 0.8/0.4 mm, passes native electrical DRC with zero opens; silkscreen cleanup and library-aware checks continue on sidefan-dft-r6. Adoption, schematic parity, updated 3D, current/thermal review and probing checks are not yet passed. The previous passive cooler acceptance cannot be used for the new sink.++Hero finish/layer metadata corrected; rendering batched from 23568 to 370 primitives with exact indexed triangle/normal and node/material checks. The optimized hero is published and visually checked. Shared viewer hidden/offscreen pause fix is proposed in https://wiki.adom.inc/adom/adom-3d-viewer/prs/1 (six visibility checks plus 111 existing browser checks pass; source candidate only, not deployed). Performance issue https://wiki.adom.inc/adom/adom-3d-viewer/issues/10 tracks the user freeze report; no measured freeze causality or GPU improvement claimed.
