The Accounts view was broadened to present a complete picture of all balances by fetching manual accounts and Plaid items regardless of active status, improving reconciliation, customer insights, and operational reporting. In parallel, the loan interest rate handling was hardened: input precision was refined from 0.01 to 0.005, and a database migration was added to raise the interest_rate column precision from 2 to 3 decimals, reducing rounding errors in pricing calculations. These efforts contribute to more reliable financial data and better product decisions.
