Silk includes an external pad-1 cue; the fab outline includes a corner cue.  **The canonical conversion remains a design candidate.** Installed adom-lbr 2.39.0 drops all per-pad mask and paste margins. Isolated development commit `19e46a6` preserves those fields, footprint defaults and explicit layer participation through KiCad, and adds signed Altium expansion fields with codec tests. The current supervisor Altium export refuses its unrepresentable rounded-corner value; Fusion explicit aperture export returns an unsupported-feature error. Native desktop parity is still unproven. See [adom-lbr issue 25](https://wiki.adom.inc/adom/adom-lbr/issues/25) and `aperture-roundtrip-audit.json`. The original roundtrip-diagnostic copies lost the attributes and must not be used for fabrication. The newer `aperture-candidate/` files preserve them; all remain unqualified.

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.
