nx_bom_rt.nx

nx_bom.nx -- GO-TO-MARKET / BILL OF MATERIALS engine. The first hardware rung made concrete: turn a gated DESIGN into a buildable bench prototype -- the real components, their cost, mass, lead time, and make-vs-buy -- with rollups (total cost, total mass, the longest-lead CRITICAL-PATH item that gates the build schedule) and per-category subtotals. Generic across any product; instantiated here for the water AWG bench prototype (advances water-system from MRL 2 toward MRL 3 = manufacturing proof of concept). INTEGER-EXACT: cost in cents, mass in grams, lead time in days. The enclosure is MAKE (we 3D-print it with our own CAD/G-code capability = vertical integration), everything else is BUY. grounded: bill_of_materials + design_for_manufacturability + contract_manufacture genealogy_id: bill_of_materials_bench_prototype + nishi_go_to_market
