What it is
Zero-based budgeting: every dollar assigned a job before the month starts. Zero-Based Budgeting is a core component of the P31 Labs sovereign cognitive infrastructure stack — built to run offline, deployed to the edge, and designed without dark patterns.
All arithmetic done client-side. Chart.js pie and bar charts update on each entry. CSV export uses the RFC 4180 format compatible with Google Sheets and Excel. Short p31ca.org URL 302 → workers.dev (probe: worker-spa-budget-tracker).
