# Feature Specification: Windows Update Rings (012)

**Feature Branch**: `feat/012-windows-update-rings`  
**Created**: 2025-12-31  
**Status**: Draft  
**Input**: `config/graph_contracts.php` (windowsUpdateRing scope)

## Overview
Add reliable coverage for **Windows Update Rings** (`windowsUpdateRing`) in the existing inventory/backup/version/restore flows.

This policy type is defined in `graph_contracts.php` and uses the `deviceManagement/deviceConfigurations` endpoint, identified by the `@odata.type` `#microsoft.graph.windowsUpdateForBusinessConfiguration`. This feature will focus on implementing the necessary UI normalization and ensuring the sync, backup, versioning, and restore flows function correctly for this policy type.

## In Scope
- Policy type: `windowsUpdateRing`
- Sync: Policies with `@odata.type` of `#microsoft.graph.windowsUpdateForBusinessConfiguration` should be correctly identified and synced as `windowsUpdateRing` policies.
- Snapshot capture: Full snapshot of all settings within a Windows Update Ring policy.
- Restore: Restore a Windows Update Ring policy from a snapshot.
- UI: Display the settings of a Windows Update Ring policy in a readable, normalized format.

## Out of Scope (v1)
- Advanced analytics or reporting on update compliance.
- Per-setting partial restore.

## User Scenarios & Testing *(mandatory)*

### User Story 1 — Inventory + readable view
As an admin, I can see my Windows Update Ring policies in the policy list and view their configured settings in a clear, understandable format.

**Acceptance**
1. Windows Update Ring policies are listed in the main policy table with the correct type name.
2. The policy detail view shows a structured list/table of configured settings (e.g., "Quality update deferral period", "Automatic update behavior").
3. Policy Versions store the snapshot and render the settings in the “Normalized settings” view.

### User Story 2 — Backup/Version capture
As an admin, when I back up or create a new version of a Windows Update Ring policy, the snapshot contains all its settings.

**Acceptance**
1. The backup/version payload in the `snapshot` column contains all the properties of the `windowsUpdateForBusinessConfiguration` object.

### User Story 3 — Restore settings
As an admin, I can restore a Windows Update Ring policy from a backup or a previous version.

**Acceptance**
1. The restore operation correctly applies the settings from the snapshot to the target policy in Intune.
2. The restore process is audited.
