Competitive Rulebook

This document defines how competition operates within URX.

It explains:

• how races are structured,
• how eligibility is determined,
• how results are verified,
• how progression is calculated,
• how ranking and enforcement work.

The Rulebook exists to ensure clarity and fairness.
If competition affects your position, it is governed by something written here.

URX is structured, but this document is not intended to be legalistic or inaccessible. It is written to explain the system clearly and consistently.

You do not need to read it cover to cover to participate.
But if you want to understand how position is earned, how metrics influence status, or how decisions are made — this is the reference.

Competition is meaningful only when rules are visible.

How to Use This Document

The Rulebook is organized into the following Parts:

• Part I — Foundational Principles
• Part II — Structure of Competition
• Part III — Participation & Eligibility
• Part IV — Race Lifecycle
• Part V — Verification & Enforcement
• Part VI — Progression System
• Part VII — Ranking & Standings
• Part VIII — Rewards & Recognition

Each Part addresses a specific layer of the system.

For a single diagram-style map of the whole engine, read System model first, then Race lifecycle overview (Part IV) and From Mechanic to Enforcement (Part V) for phase and enforcement detail. Structural states (Part I) defines Results out and the canonical race state enum.

Procedural sections describe how competition operates.
Appendix A describes structural models for progression metrics; Appendix B describes how those models may be updated and what stays fixed after Results out. Legal terms (Terms of Service, privacy) live outside this Rulebook where URX publishes them.

When material rules or algorithms change, URX communicates updates through the channels it designates (for example product release notes or Rulebook revision). Appendix B (Algorithm governance) states the intent for forward updates and non-retroactivity for finalized races.
