# Application Operation Rules

- `operations/` coordinates asynchronous editor use cases such as generation, import, raster processing, and export.
- Operations may read immutable state snapshots, call injected platform capabilities, and dispatch commands.
- Operations must never mutate `ImageDocument` or `EditorState` directly.
- Keep React, DOM elements, WebGL objects, server-only APIs, and concrete network details out of operation contracts.
- Prefer dependency injection for platform behavior so operation control flow remains testable.
