# NexusOS Licensing Architecture

NexusOS operates under a clear, three-tier licensing model designed to ensure the longevity of the core while fostering a vibrant ecosystem.

## 1. Core Logic: SSS v1.0
**Protected Stewardship.**
The kernel (Rumk), build toolkit (nexus), and package manager core (nip) are licensed under the **Self Sovereign Society License (SSS v1.0)**.
- **Goal**: Prevents proprietary forks of the core infrastructure. Ensures the "Constitution" of the OS remains intact.
- **Copyleft**: Modifications to SSS-licensed files must be shared back.
- **Commercial Use**: Allowed, provided the core remains open.

## 2. Extensions & Glue: Apache 2.0
**Pragmatic Integration.**
Drivers, adapters, and glue code (especially Zig C-interop layers) are licensed under **Apache 2.0**.
- **Goal**: Maximizes compatibility with existing hardware and software ecosystems.
- **Flexibility**: Can be mixed with proprietary drivers if absolutely necessary (though discouraged).

## 3. Community Content: CC0 (Public Domain)
**Unrestricted Knowledge.**
Documentation, recipes, and logic-less configs are **CC0**.
- **Goal**: Frictionless sharing of knowledge. No attribution bureaucracy for using a recipe or learning from docs.

## Summary
| Component | License | Why? |
|-----------|---------|------|
| **Rumk / Nexus Core** | SSS v1.0 | Protect the foundation. |
| **Drivers / Glue** | Apache 2.0 | Maximum hardware support. |
| **Docs / Recipes** | CC0 | Free exchange of ideas. |

We have removed the ACUL (Artificial Consciousness Usage License) to streamline adoption.
