This prevents KiCad from scaling the opening corner radius with the copper-pad ratio. [Inspect the newer native geometry](https://wiki.adom.inc/adom/tps389001dser/render/explicit-aperture-candidate/aperture-inspection.html). All twelve native opening sizes and R0.05 mm radii match the saved intent within the SVG's coordinate precision. The six electrical connections remain 1→1 through 6→6. Earlier files and the failing corner example are preserved separately.  The dedicated 5 mm coupon's native DRC reports two copper clearance findings (0.15 mm actual vs default 0.20 mm) and a reference-text edge clipping warning. The detailed native report is authoritative; the service CLI incorrectly summarized zero findings. The InstaPCB skill specifies 0.10 mm minimum spacing, but this coupon did not carry a complete InstaPCB project rule set. This is therefore geometry evidence, not a passing manufacturing DRC. Default ignored checks, including footprint-type mismatch, remain recorded in the native report. Independent copper-land review, native target adapters, model seating and full board qualification remain open.++## Related projects++[TMF8829 Depth Lab](https://wiki.adom.inc/adom/tmf8829-depth-lab) uses this component.
