# Public declaration index

> **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).

Exact declarations from the pinned revision. Each entry links its integration recipe and a complete header snapshot, including field comments, methods, overloads and Unreal reflection annotations. Snapshots include private members for context; those remain implementation details, not supported authoring hooks. Forward declarations and inherited engine APIs are not duplicate inventory entries.
