# QuartzUIGASResolver: declaration reference

> **0.57.0-dev · beta source documentation.** Native, Blueprint, Editor and rendering examples are source-reviewed, not executed in Unreal during this scan. See [validation and limits](https://betterbuilt.games/docs/quartz-ui/evidence).

Pinned source (source: `Source/QuartzUIGAS/Public/QuartzUIGASResolver.h`) · [integration recipe](https://betterbuilt.games/docs/quartz-ui/inventory#quartzuigasresolver) · [practical guide](https://betterbuilt.games/docs/quartz-ui/integrations)

## UQuartzUIGASResolver

**Public type.** Exact-player ASC resolver; the default supports PlayerState-, pawn-, and controller-owned GAS.

**Prerequisites / integration:** Exact-player view plus native asset/source ownership; GAS additionally requires GameplayAbilities. Use the [QuartzUIGASResolver recipe](https://betterbuilt.games/docs/quartz-ui/inventory#quartzuigasresolver) in the host module `QuartzUIGAS`.

**Minimal example / lifecycle:** Subclass resolver for unusual ownership; assign to binding configuration. Resolved ASC must still belong to exact local player.

**Avoid:** Returning a convenient foreign ASC or bypassing ownership guard. Match the exact declaration below; dependent DTOs/enums are values used by this owner, not independent systems.

## Complete header

Source snapshot, not an additional example. Unreal annotations distinguish exposed Blueprint nodes from native-only/private methods.
