# Current mounting and USB verification

Saved board SHA-256: `a261317dc5ba675ad0bc012489fdf99ec7cd64299d3db6f8985828f6757781d6`. Source, actual Gerber outline and Excellon drill files agree on 35 × 35 mm and four Ø3.2 mm NPTH holes at exactly (±13, ±13). Native STEP screening passes for the approved upward USB insertion, two defined 10 mm housings at 12.1 mm pitch, and a Ø4.4 × 3 mm head envelope around the required maximum Ø4 mm fastener heads.

The nominal cable-housing gap is 2.100 mm. Actual supplier footprints/courtyards and models are retained. See [engineering fixes](engineering-fixes.md), `artifacts/mechanical/mount-usb-screen.json`, `artifacts/mount-drill-verification.json` and the actual CAM audit for current evidence.

Both primary and order-review manufacturing archives pass their full CAM audits. Passive-orientation advisories remain reviewable in the native placement log. The publication gate rejects other diagnostics and any real geometry/CAM failure.

The manufacturer motor drawing dimensions front holes only. Rear motor fit, adapter geometry, physical cable/fastener tolerances, assembly stack/thread engagement and hardware operation remain unverified.
