about

nx_bond_gate.nx -- FIXED-INCOME VALUATION GATE. Proves exact integer bond pricing (par/discount/premium), yield-to-maturity by bisection round-tripping on both sides of par, the fail-closed refusals (unreachable price, non-positive price), Macaulay and modified duration, current yield, and price monotonicity in yield. All values hand-verified with the same downward-truncation the library uses. license_tier: ORIGINAL No hw writes (Rule 26). expect_exit: 0
