# Personal Freedom Index Public Spec

## Purpose

Personal Freedom Index is a structural self-analysis instrument for estimating personal freedom under real-world constraints.

Important: this index does **not** measure happiness or life satisfaction.

## Canonical Data Source

For tooling and AI clients, use:

- `/spec/personal_freedom_index_spec.json` (application/json)

This JSON includes:

- question bank (`ja` / `en` / `zh`)
- scoring formula and tier definitions
- `scoring.naApplicabilityPolicy`: **N/A is only for objective non-applicability** (see project spec §5.1.1); not a generic “skip”
- category metadata
- flow and notes for external simulation

## Human Specification

Project-level detailed Japanese spec:
