# FR Y-14 Capital Worksheet Roll-Forward & Cross-Check

`POST /v1/tools/rollforward_y14_capital_worksheet`

## Request

- Base URL: `https://ainumbers.co`
- URL: `https://ainumbers.co/v1/tools/rollforward_y14_capital_worksheet`
- Auth: none declared

Rolls forward a caller-declared FR Y-14A/Q capital worksheet (CET1, additional Tier 1, Tier 2) from beginning balance through period additions and deductions to an ending balance, applies a caller-declared published-scenario adjustment (e.g. a Federal Reserve DFAST/CCAR severely-adverse published-scenario delta), and cross-checks the computed ending total capital against a caller-declared reported total-capital figure sourced from another schedule (e.g. FR Y-9C Schedule HC-R, art-436) within a caller-declared tolerance. Not a filer -- produces evidence artifacts and worksheet totals only, never a submission. All roll-forward line items, the scenario adjustment amount, and the cross-check reference figure are caller-declared; this tool performs only roll-forward arithmetic (beginning + additions - deductions + scenario adjustment = ending) and a tolerance comparison, never capital-component classification, scenario modeling, or projection -- firm capital-planning models (PPNR, loss forecasts, scenario translation into balance-sheet impact) stay strictly outside this boundary. Complements art-436 (BHC Schedule HC-R capital) as an independent roll-forward/cross-check, not a replacement for it.
