OpenProof — RPO Specification v0.1

Integrity • Readability • Verifiability

---

Overview

OpenProof defines an open, verifiable standard for digital evidence:
RPO (Rapport Probatoire Ouvert) — a dual-format proof combining:

• Signed JSON: structured and machine-readable data
• Human-readable PDF: traceable, timestamped narrative output
• Public hash: unique integrity key for audit and verification

This specification aims to make truth measurable, power traceable, and coherence verifiable across legal, institutional, and research contexts.

---

Core Principles

1. Integrity — Every proof object must be cryptographically sealed.
2. Readability — Every human must be able to interpret the same data.
3. Verifiability — Every institution must be able to check it publicly.
