 ## Purpose
 
 Central catalog for **non-combat** skill metadata: **stable IDs**, **categories**, **allowed XP sources**, and unlock prerequisites. All prototype activities reference skills by **`SkillDef.id`** validated against this registry. **Combat role progression** is **not** a `SkillDef`—use gig progression ([`docs/game-design/gigs.md`](../../game-design/gigs.md)).
