# Maintain

These pages concern changes to `@dg/ui` itself, not applications built with it.

- [Toolkit evolution](evolution.md): stability, version policy, the maintenance process and release checks.
- [Reference document format](format.md): Markdown extraction contract for components, foundations and section indexes.
- [Independent agent evaluation](agent-evaluation.md): briefs and criteria for measuring documentation usability.
- [Toolkit changes](changes.md): public changes and migrations by version.

The [package instructions](../../AGENTS.md) describe maintenance ownership; [workspace checks](../../../../README.md#checks) are the command reference.
