PACT OS — Personal Productivity & Accountability System

Turn Intent Into Discipline. A production-grade, local-first personal productivity and accountability OS built with Next.js 16, React 19, TypeScript, Tailwind CSS v4, and PostgreSQL via Supabase.

⚡ What is PACT OS?

PACT OS is a unified personal operating system designed to bridge the gap between setting ambitious goals and consistently executing daily actions. It provides time-blocked planning, integer-cent financial ledger discipline, habit streak tracking, deep work focus timers, and a server-authoritative commitment engine with real-world consequence bindings.

🎯 The Problem

Traditional productivity tools suffer from passive tracking:

• Tasks can be infinitely postponed without friction or accountability.
• Financial trackers rely on floating-point approximations causing rounding inaccuracies.
• Focus tools depend on external streaming audio services causing privacy leaks.
• Productivity platforms lack proof-of-work integration with real-world developer tools.

🧠 The Idea & Core Philosophy

PACT OS introduces Server-Authoritative Commitments:

1. Binding Deadlines: Commitments carry explicit, non-bypassable deadlines.
2. Consequence Sealing: Default consequences are sealed to commitments and triggered automatically upon deadline expiration.
3. Integer-Cent Math: Currency is strictly calculated in integer cents to guarantee financial ledger precision.
4. Local-First & Offline: Deep work audio and local caching run 100% offline without telemetry.

🔐 Core Engineering Principles

1. Integer-Cents Financial Math: Zero floating-point math for currency calculations (src/lib/money.ts).
2. Server-Authoritative Time: Server clock evaluates all deadlines (deadline_at) to prevent client clock manipulation.
3. Row Level Security (RLS): 100% of database tables enforce auth.uid() = user_id.
4. Frozen Database Migrations: 26/26 PostgreSQL database migrations are frozen and protected.
5. Testing & QA Matrix: Validated against 56 domain test suites with 0 lint or type errors.
