# Documentation: Enhance SortZone with intent-driven JSDoc

Refactor `src/draggable/container/SortZone.mjs` to include comprehensive, intent-driven class documentation.

Focus on explaining:
- The core responsibility of sorting items.
- The window-drag detachment workflow.
- The layout expansion logic (`calculateExpandedLayout`).
- The snapshot-based state restoration.

This ensures the complex logic introduced in #8141 is maintainable and discoverable for future AI sessions and developers.

**Input from Gemini:**

> ✦ I have completed the documentation overhaul for `src/draggable/container/SortZone.mjs`.
> 
> Beyond the initial scope of the class summary, I also significantly enhanced the method-level JSDoc to ensure the complex window-detachment and sorting logic is fully explained for future maintenance.
> 
> **Enhanced Documentation Includes:**
> *   **Class Level:** Detailed the architecture, window detachment workflow, and interaction with `DragDrop` addon.
> *   **`calculateExpandedLayout`:** Explained the math behind gap inference and flex-aware space distribution.
> *   **`startWindowDrag`:** Documented the specific steps for detaching a window (hiding proxy, expanding layout).
> *   **`onDragMove`:** Clarified the dual logic for window re-entry (layout restoration) vs. standard sorting.
> *   **`onDragStart` & `onDragEnd`:** detailed the snapshotting and cleanup processes.
> *   **`switchItems`:** Explained the geometry swapping logic.
> 
> The file is now well-documented and ready for "future us".
