# Core UI Integration Validation

This directory contains the manual XCUI validation system for shared Core primitives.

Structure:

- `shared/`: shared host, native renderer, screenshot helper, scenario registry
- `input/`: shared input validation category
- `layout/`: shared layout validation category
- `style/`: shared theme token and style resolution validation category
- `text/`: shared UTF-8 text rendering and textInput focus marker validation category

Rules:

- One scenario directory maps to one executable.
- Do not accumulate unrelated checks into one monolithic app.
- Shared infrastructure belongs in `shared/`, not duplicated per scenario.
- Screenshots are written only under the active CMake build directory.
- The output root is the executable directory: `.../Debug/captures/<scenario>/`.

Build:

```bash
cmake --build build --config Debug --target core_ui_integration_tests
```
