nx_market_cmp.nx

nx_market_cmp.nx -- CROSS-MARKET COMPARISON library (arc=ANALYST rung AN10): the operator's "wholesale feedback, overseas feedback -- ALL the information so it is irrefutable". The irrefutability move: the v2 explanation ("the price is the delivery STRUCTURE, not the machine") makes a TESTABLE cross-border prediction -- equipment is globally traded so its per-ton price should be roughly comparable across markets, while the structure layer (labor/licensing/margin) is local and should vary wildly. This organ MEASURES both spreads from a .cmp data file and issues a deterministic verdict: STRUCTURE-DOMINANT iff the structure-per-ton spread exceeds the equipment-per-ton spread. Same independence rule as .led: a market backed by <2 distinct incentive classes is PROVISIONAL (named, never silently trusted). Grammar (integers only; '#'/blank = comment): T <ref_market> (exactly one; ratios are vs this market) S <rel> <cred> <party> <method> <class> (source; idx = order) M <price_cents> <ton_x10> <equip_cents> (market; idx = order) B <market> <src> (backing edge) Composes nx_ledger_data (int/line parsing helpers) + nx_source_grade (grades, independence). LAWS: struct-free, integer-only, flat ifs, <=6 args. license_tier: ORIGINAL
