How kandatiranjithkumarreddy/borrower-copilot works

Borrower Copilot is a client-side loan self-assessment and negotiation aid. A borrower starts on the landing page, enters a profile and loan details in the adaptive questionnaire, and the app passes that input to a deterministic assessment engine. The engine derives affordability, loan amounts, rates, EMI/APR, stress resilience, confidence, and a borrowing recommendation, then builds negotiation guidance for results presentation. The README documents these capabilities; some UI and engine modules were not sampled, so their internal links are shown only where the excerpts or README support them.
