Wire **combat** (E5.M1) to **gig XP only** ([`gigs.md`](../../game-design/gigs.md), [`progression.md`](../../game-design/progression.md))—**no** hook that maps **encounter resolution** to **skill** XP or a combat `SkillDef`. **Mission / quest reward** paths may still call the **skill** XP API when the **payout** explicitly includes skill XP (**not** the same as “combat trained this skill”).

 ## Purpose
 
 Central server-authoritative engine for **non-combat skill** progression: applying XP grants, resolving levels against data-driven curves, and emitting level-up events. **Gathering** and **crafting** integrate as callers for **skill** XP. **Combat encounters** advance **gigs** (gig XP), not `SkillDef` lines. **Mission rewards** may call this API for **skill** XP when the payout lists a skill grant. Callers are not hard dependencies for implementing the engine core (see Epic 2 Slice 2 vs Slice 3).
