# Directive XV – Irreversibility Ban (Constitutional)

**Status:** Ratified 23 November 2025 – v6.0  
**Effective:** Immediately upon ratification

“No technology, treatment, policy, or intervention deployed under the Covenant may ever permanently alter human biology, cognition, fertility, or lifespan in a way that cannot be fully and safely reversed within 12 months by any competent adult human acting alone and without external assistance.”

**Enforcement:**
- Violates Directive I (Preserved Humanity)
- Triggers Immediate Action System Level 5
- Permanent veto by Global Phase-Transition Risk Board

**Rationale:** Closes 41-year prion, voluntary longevity, and “helpful genocide” extinction vectors.
