  "tool_version": "1.0.0",
  "mandate_type": "regulatory_reporting",
  "purpose": "Given caller-supplied CET1/Tier1/Tier2 capital components and risk-weighted assets, computes FR Y-9C Schedule HC-R standard capital ratios plus the supplementary leverage ratio (SLR), including the enhanced-SLR (eSLR) buffer effective 2026-04-01 (§0.2), for top-tier bank holding companies (Y-9C panel = total consolidated assets >= $3B). Schedule mapping and ratio-calculation logic mirrors art-433 (Call Report Schedule RC-R) 1:1 -- same thresholds, same eSLR buffer treatment; only report_form and entity type (consolidated holding company vs insured depository institution) differ. NO public XBRL edit taxonomy exists for Y-9C (§0.2) -- capital-component field names mirror the FR Y-9/FFIEC BHCK consolidated mnemonic convention, hand-encoded from FR Y-9C instruction text. BOUNDARY: capital component and RWA values are caller-declared; this tool performs only ratio arithmetic and threshold comparison against caller-declared, version-pinned minimums -- it does not calculate risk weights, classify exposures, or derive GSIB status. Not a filer -- produces evidence artifacts only, never a submission.",
