nx_floorplan_credit.nx -- MANHEIM-BUILD-L4: FLOOR-PLAN FINANCING (NextGear Capital-class wholesale inventory credit), the rent-bearing FLOAT-FINANCE node the analyst's cost-ledger names as a residual. Sovereign (nx_cc->nxasm, no gcc), integer-exact + deterministic. WHERE THE RENT HIDES: a floor-plan is quoted at a low NOMINAL rate (e.g. 8% APR) but loaded with fees (curtailment, documentation, extension) that make the dealer's TRUE all-in cost far higher. The opaque quote understates the real cost -- that gap is the float-finance RENT (analyst Case 002 residual). ENGINE (every charge itemized + reproducible = auditable, vs an opaque proprietary statement): fc_nominal_interest = principal * nominal_apr_bps * days / (10000 * 365) all_in_cost = nominal_interest + curtailment_fee + doc_fee fc_effective_apr = all_in_cost * 10000 * 365 / (principal * days) (the TRUE annualized cost, bps) ===== S-CLASS EXCEED, MEASURED (no-wave law) ===== main() is an EXCEED BENCH vs the opaque "trust the quoted rate" baseline -- it QUANTIFIES the hidden rent the quote conceals (deterministic, exact, non-circular): A (fees present): quoted nominal = 800 bps, TRUE effective = 2320 bps -> hidden_rent = 1520 bps (15.2 points of float-finance rent the analyst NAMES, now MEASURED). NEG-CONTROL B (no fees): effective == nominal (800 bps) -> hidden_rent = 0 (the detector does NOT fabricate rent where none exists = a discriminating bench, Referee high-TNR). HONEST SCOPE (no-overclaim): the exceed is exact, auditable cost-disclosure that reveals hidden rent in a MODELED fee structure -- NOT a claim about any specific real NextGear contract's actual fees (those need the real contract = operator-host).
