# Implementation Plan: Windows Update Rings (012)

**Branch**: `feat/012-windows-update-rings`  
**Date**: 2025-12-31  
**Spec Source**: [spec.md](./spec.md)

## Summary
Make `windowsUpdateRing` snapshots/restores accurate by correctly capturing and applying its settings, and present a readable normalized view in Filament.

## Execution Steps
1.  **Graph contract verification**: Ensure `config/graph_contracts.php` entry for `windowsUpdateRing` is correct and complete.
2.  **Snapshot capture hydration**: Extend `PolicySnapshotService` to correctly hydrate `windowsUpdateForBusinessConfiguration` settings into the policy payload.
3.  **Restore**: Extend `RestoreService` to apply `windowsUpdateRing` settings from a snapshot to the target policy in Intune.
4.  **UI normalization**: Add a dedicated normalizer for `windowsUpdateRing` that renders configured settings as readable rows in the Filament UI.
5.  **Tests + formatting**: Add targeted Pest tests for snapshot hydration, normalized display, and restore functionality. Run `./vendor/bin/pint --dirty` and the affected tests.
