# Link Sync Settings

**Status: Planning**

## Summary

When a user enables quality profile sync, require media management sync to also be
enabled. This ensures users get the complete configuration — profiles alone without
proper naming formats leads to inconsistent results.

## Problem

Users can currently enable quality profile sync without enabling media management
sync. This creates issues:

- Quality profiles define *what* quality to grab
- Media management defines *how* files are named and organized
- Without both, the naming format may not match what the profile expects
- Leads to confusion and support requests

## Solution

Client-side validation on the sync settings page. Don't let users save if:

1. Any quality profiles are selected for sync, AND
2. Media management settings (naming, quality definitions) are not configured

## Implementation

**Location:** `src/routes/arr/[id]/sync/+page.svelte`

**Logic:**

```typescript
// Check if any quality profiles are selected
const hasQualityProfilesSelected = Object.values(qualityProfileState)
  .some(db => Object.values(db).some(selected => selected));

// Check if media management is configured
const hasMediaManagement =
  mediaManagementState.namingDatabaseId !== null ||
  mediaManagementState.qualityDefinitionsDatabaseId !== null;

// Validation
const canSave = !hasQualityProfilesSelected || hasMediaManagement;
```

**UX:**

- Show warning message when quality profiles selected but no media management
- Disable save buttons on QualityProfiles component until valid
- Message: "Quality profiles require media management settings. Please configure
  naming or quality definitions to ensure consistent file naming."

## Checklist

- [ ] Add validation logic to `+page.svelte`
- [ ] Pass `canSave` state to `QualityProfiles.svelte`
- [ ] Show warning alert when invalid
- [ ] Disable save button when invalid
