  "brief": "Produce a LIGHT mechanical planning package for the exact supplied adjustable bench fixture. The separately authored CAD implementation targets 20 meaningful components: base, guide rods, supports, jaws, pads, bushings, lead screw, nut, hand knob and feet. This is a substantial multipart mechanism, not a validated clamp or purchased-part specification. Keep 3 modules, 2 stories each: structural/support parts; manual jaw adjustment/interfaces; assembly and proposed bench checks. Review coordinate consistency, jaw opening, screw/guide clearances, component/BOM interfaces and assembly sequence. Fits, screw threads, contact/friction and available travel are simplified and unvalidated. No motor, power tool interface, hazardous load, actual sample damage test, fabrication or certified holding-force claim. Surface conflicts rather than changing the locked parameter contract. CAD implementation and geometric measurements happen separately after your review. Include a useful assembly/check flow diagram and compact BOM organized by the actual proposed parts.",
