BudgetTracker.

plans/budget-tracker.md

Overview

Personal-finance app with category budgets, recurring transactions, monthly variance tracking, CSV import. Financial-arithmetic precision (no float) and time-series budget vs. actual.

What you're reading is the same plans/budget-tracker.md spec used to build BudgetTracker. It lists what's in the source, what isn't, the audit results, and the architecture. Read it before you subscribe — there are no surprises on the other side of payment.

Full spec is being authored — the rich detail page (features, audit numbers, changelog, recipes, architecture) lands when this starter ships.
