FR Y-9C Schedule HC to HC-R Capital Chain

Gated two-step chain for top-tier bank holding companies (Y-9C panel, total consolidated assets >= $3B). Step 1 maps caller-declared Schedule HC balance-sheet line items into Schedule HC totals and checks the balance-sheet identity. Step 2 consumes those totals alongside caller-supplied capital components to compute Schedule HC-R capital ratios and the supplementary leverage ratio, gated dual_control(2) before the capital-adequacy result is treated as final -- any failed capital-ratio or SLR threshold requires two distinct approver sign-offs (recorded, not yet runtime-gated pending HA-RETRO-1 wiring).

Bhc Schedule Hcr Capital art-436-bhc-schedule-hcr-capital

CET1/Tier1/Total capital ratios and SLR against caller-declared, version-pinned minimums; gated dual_control(2) on a failed capital-ratio result. Final stage.

§27 Human Accountability gate: total_capital_pass=false requires dual_control(2) -- two distinct approver identities -- before the result is treated as final (recorded now, runtime-enforced once HA-RETRO-1 wires this gate).
