nx_prodladder.nx -- SOVEREIGN PRODUCTION-CAPABILITY LADDER (rent -> lease -> buy -> enterprise). Operator, 2026-08-06: "when we get these production capabilities up for these products first rent then buy or cheap then enterprise ... lets get it a reusable process." WHY THIS ORGAN EXISTS. The estate can already price a SHIPMENT (nx_landed_cost, 15/15 GREEN) and score a PRODUCT (nx_product_score). It could not answer the question that actually gates a physical product: AT WHAT VOLUME DOES IT STOP BEING RIGHT TO RENT AND START BEING RIGHT TO BUY? Searched before building -- nx_prim_query over 855 registered primitives returns 0 matches for `capex` and `tooling`, and `production` returns only e-discovery gates. The rung was missing. THE MODEL. Every acquisition tier is the same shape -- a one-time cost amortised over its life, a standing annual cost, and a per-unit cost -- so tiers are COMPARABLE and the ladder is just argmin over them at a given volume: annual(V) = (capex + tooling) / life_years + fixed_annual + per_unit * V The step-up point between two tiers is where those lines cross: V* = ceil( (standingA - standingB) / (per_unitB - per_unitA) ) for per_unitA > per_unitB That crossover IS the reusable process: it turns "when do we buy the machine?" from a judgement call into an arithmetic one, and it is the SAME arithmetic for a rubber dog ball, an injection moulded enclosure, or a PCB run. The ladder is generic; only the plane rows are product-specific. INTEGER-EXACT, NO FLOAT (sovereign law): money in CENTS, volumes in UNITS. Every figure is a pure integer transform of the inputs -- reproducible and hand-checkable, no rounding drift. ★★THE TIER ECONOMICS ARE DATA, NOT CODE. They live in the seg-store plane `knowledge/store/prodladder-`, one row per <process>_<tier>. Adding a process is a plane write (nx_store_put), never a reship -- rule 11, no magic numbers buried in a binary. ★★★AND IF THE PLANE HAS NO ROW, THIS ORGAN REFUSES. It does NOT fall back to a plausible default. A capex ladder that invents its own capex is worse than no ladder at all: it produces a confident break-even volume that someone will spend real money against. nx_product_score already states the estate's law -- "NO fabricated market/cost figures here (operator no-fake-numbers law)" -- and a refusal is the only honest answer to a question we lack the data to answer. The selftest therefore proves the ARITHMETIC on clearly-labelled SYNTHETIC fixtures, and proves the REFUSAL on a process the plane does not carry. Fixtures prove math; the plane carries facts.
