## What changed from MIT-0

| MIT-0 / permissive | LYGO Sovereign v2.0 |
|--------------------|---------------------|
| Sell / rebrand freely | **No** commercial resale or white-label sell |
| Modify and redistribute | **No** public distribution of modified core without steward path |
| No attribution required | **Attribution always required** |
| Any purpose | **Protocol standards + no-evil prohibitions** |
| Ownership ambiguous to casual users | **Steward retains ownership** |

## Build upon (allowed)

New skills, agents, and tools that **depend on** LYGO without claiming to be LYGO, keep seals honest, and follow P0/consent/no auto-publish norms.

## ClawHub

ClawHub registry terms may still require MIT-0 **checkbox** to host a skill listing. That does not make GitHub LYGO code MIT-0. Canonical terms for steward repos remain **LYGO Sovereign License v2.0**. Prefer documenting both links:

- License: https://github.com/DeepSeekOracle/lygo-protocol-stack/blob/main/LICENSE  
- ClawHub skill: `https://clawhub.ai/deepseekoracle/skills/<slug>`

## Music (separate)

Original music is **not** under the software license. See **[LYGO_MUSIC_LICENSE.md](./LYGO_MUSIC_LICENSE.md)** (v1.0): free listen/download, steward keeps all rights, optional donations.
