  "mandate_type": "risk_parameter",
  "purpose": "Recomputes a caller-declared cross-border payment corridor's cost gap against the hardcoded G20/FSB roadmap targets: retail cross-border payments end-2027 (no more than 1% global average, no more than 3% any corridor) and remittances 2030 (no more than 3% global average, no more than 5% any corridor). The caller supplies the corridor's observed total-cost percentage (as integer basis points), sourced from World Bank Remittance Prices Worldwide (RPW, methodology Q325) or elsewhere; this kernel never vendors RPW's own corridor cost table, only the published target arithmetic. Zero live FX/rate calls. These are transparency and benchmarking targets, not an enforceable deadline against any single firm -- not a compliance-gate. Not the US Reg E remittance disclosure recompute (see art-reg-e-remittance-disclosure-check for that).",
