## Overview

Vantage is a browser-based credit decision and post-disbursement monitoring platform. Credit staff enter or edit an application in the analysis screen, which persists borrower records; the documented engine evaluates eligibility, weighted scores, benchmark gaps and safe loan sizing. Portfolio, borrower-list, detail and settings screens provide review and configuration. The app dispatches screens, while detail-screen EWS updates are judged and saved. README capabilities are included where source wiring is not shown; those uncertain connections are intentionally omitted.

Main entry points: [`src/app.js`](https://github.com/mynameanonim43-ship-it/de-core-credit-decision-engine-dashboard-/blob/main/src/app.js) (App router), [`src/data/store.js`](https://github.com/mynameanonim43-ship-it/de-core-credit-decision-engine-dashboard-/blob/main/src/data/store.js) (Borrower store), [`src/screens/detail.js`](https://github.com/mynameanonim43-ship-it/de-core-credit-decision-engine-dashboard-/blob/main/src/screens/detail.js) (Borrower detail), [`src/core/scoring.js`](https://github.com/mynameanonim43-ship-it/de-core-credit-decision-engine-dashboard-/blob/main/src/core/scoring.js) (Pillar scoring)
