      "description": "Run a bank's own exposure book and business-indicator inputs through the 2026 Basel Endgame reproposal (BCBS/US NPR, reproposed 2026-03-19, comments closed 2026-06-18, final expected ~Q4 2026): credit-risk ERBA/standardized RWA (art-355), operational-risk SMA business-indicator and internal-loss-multiplier component (art-356), and the output-floor phase-in path (art-358) run in parallel off the same book, then a 2023-vs-2026 capital-delta comparator (art-357) reproduces the headline relief story on the caller's own numbers. rule_status stays proposed throughout -- every stage carries the reproposal's provisional status and this chain is due for a re-pin WU at finalization (~Q4 2026).",
