    "Draft 002's centered circular four-hole pattern with 70 mm pitch radius is infeasible for the assumed 120 mm by 80 mm rectangular base: hole centers at +/-70 mm exceed the half-length 60 mm and half-width 40 mm extents, before even considering 8 mm hole diameter edge clearance.",
    "The source asks for four equally spaced mounting through holes, but does not require a circular bolt pattern; a feasible rectangular/symmetric pattern or a smaller pitch radius should be specified."
