The exact MPN is a virtual identification inlay generated by `adom-chip-laser`, not a claim about the manufacturer’s actual package marking. The physical source model and reference-artwork geometry remain unchanged.++The Source field links to the manufacturer/reference authority.

Native CAD parity and manufacturing qualification are separate checks.
