THE CONSTRAINT

Why the problem resisted an easy answer.

Most consumer budgeting products assume vendor-hosted data, recurring subscriptions, or a single decision-maker. This product needed deterministic accounting, useful household collaboration, and a local-first architecture without turning into another generic expense tracker.
