+# Feature 003: Manual Testing Checklist
+
+## Prerequisites
+
+1. **Start the application:**
+   ```bash
+   ./vendor/bin/sail up -d
+   ./vendor/bin/sail artisan serve
+   ```
+
+2. **Access Filament admin:** http://localhost/admin
+
+3. **Create test tenant with Settings Catalog policy** (or use existing)
+
+---
+
+## T023: Verify JSON Tab Still Works
+
+**Task:** Ensure JSON tab navigation and functionality from Feature 002 is intact
+
+### Steps:
+1. Navigate to `/admin/policies`
+2. Click on a **Settings Catalog** policy
+3. Verify **two tabs** are visible: "Settings" and "JSON"
+4. Click "JSON" tab
+5. Verify JSON viewer renders the policy snapshot
+6. Click copy button next to JSON content
+7. Paste into text editor - should contain valid JSON
+
+### ✅ Success Criteria:
+- [ ] Both tabs render
+- [ ] Tab switching works
+- [ ] JSON content displays correctly
+- [ ] Copy button functional
+- [ ] No JavaScript errors in browser console
+
+### ❌ Failure Handling:
+If JSON tab is broken, check:
+- Browser console for errors
+- `pepperfm/filament-json` package installation
+- PolicyResource.php tabs configuration
+
+---
+
+## T024: Verify Fallback for Uncached Definitions
+
+**Task:** Check UI shows prettified labels when definitions are not cached
+
+### Setup:
+Create a policy with an unknown definition ID:
+```php
+php artisan tinker
+$policy = Policy::factory()->create([
+    'policy_type' => 'settingsCatalog',
+    'display_name' => 'Fallback Test Policy',
+]);
+
+PolicyVersion::create([
+    'policy_id' => $policy->id,
+    'tenant_id' => $policy->tenant_id,
+    'version_number' => 1,
+    'policy_type' => 'settingsCatalog',
+    'platform' => 'windows',
+    'snapshot' => [
+        '@odata.type' => '#microsoft.graph.deviceManagementConfigurationPolicy',
+        'settings' => [[
+            'settingInstance' => [
+                'settingDefinitionId' => 'device_vendor_msft_uncached_test_setting',
+                'simpleSettingValue' => ['value' => 123]
+            ]
+        ]]
+    ],
+    'created_by' => 'test@example.com',
+    'captured_at' => now(),
+]);
+```
+
+### Steps:
+1. Navigate to the created policy view
+2. Open Settings tab
+3. Look for setting display
+
+### ✅ Success Criteria:
+- [ ] Page renders without crash
+- [ ] Setting shows prettified label: "Device Vendor Msft Uncached Test Setting"
+- [ ] No error messages displayed
+- [ ] Value (123) displays correctly
+- [ ] No JavaScript errors
+
+### ❌ Failure Handling:
+- If crash occurs, check SettingsCatalogDefinitionResolver fallback logic
+- If raw ID shows, check PolicyNormalizer prettifyDefinitionId() method
+
+---
+
+## T025: JSON Viewer Scope
+
+**Task:** Ensure JSON viewer only renders on Policy View page
+
+### Steps:
+1. Navigate to `/admin/policies` (list view)
+2. **Verify:** No JSON viewer appears on list page
+3. Navigate to `/admin/tenants`
+4. **Verify:** No JSON viewer on tenant list
+5. Click on a tenant detail page
+6. **Verify:** No JSON viewer on tenant detail
+7. Navigate back to **Policy View** page
+8. **Verify:** JSON viewer present ONLY here
+
+### ✅ Success Criteria:
+- [ ] JSON viewer ONLY on Policy View page
+- [ ] Not globally injected into all Filament pages
+- [ ] No console errors on other pages
+
+---
+
+## T034: Display Names vs Raw IDs
+
+**Task:** Verify Settings tab shows human-readable names, not definition IDs
+
+### Steps:
+1. Warm cache for a policy:
+   ```bash
+   ./vendor/bin/sail artisan app:warm-settings-catalog-definitions
+   ```
+
+2. Navigate to Settings Catalog policy view
+3. Open Settings tab
+4. Inspect setting labels
+
+### ✅ Success Criteria:
+- [ ] Labels show display names: "Allow Real-time Monitoring"
+- [ ] Raw definition IDs NOT visible: `device_vendor_msft_policy_config_defender_allowrealtimemonitoring`
+- [ ] Help text appears below labels (if available)
+- [ ] Category grouping visible (e.g., "Windows Defender Antivirus")
+
+---
+
+## T035: Value Formatting
+
+**Task:** Verify setting values are formatted appropriately
+
+### Test Cases:
+
+#### Boolean Values:
+- [ ] `true` shows as "Enabled" or badge
+- [ ] `false` shows as "Disabled" or badge
+
+#### Integer Values:
+- [ ] Large numbers formatted: `12345` → `12,345`
+- [ ] Small numbers display as-is: `5` → `5`
+
+#### String Values:
+- [ ] Short strings display fully
+- [ ] Long strings truncated with "..." (hover for full text)
+
+#### Choice/Enum Values:
+- [ ] Shows human-readable label (if available)
+- [ ] Falls back to choice value if label missing
+
+### ✅ Success Criteria:
+All value types render clearly and are visually distinct
+
+---
+
+## T036: Search/Filter Functionality
+
+**Task:** Test client-side search filtering
+
+### Steps:
+1. Navigate to Settings Catalog policy with **multiple settings** (10+)
+2. Locate search box above settings list
+3. Type "defender" in search box
+4. **Verify:** Only settings with "defender" in name/description remain visible
+5. Clear search box
+6. **Verify:** All settings reappear
+7. Test case-insensitive search: "DEFENDER"
+8. **Verify:** Still filters correctly
+
+### ✅ Success Criteria:
+- [ ] Search box present
+- [ ] Instant filtering (no page reload)
+- [ ] Case-insensitive matching
+- [ ] Clear/reset works
+- [ ] No JavaScript errors during search
+
+---
+
+## T042: Full QA Walkthrough
+
+### Complete User Journey:
+
+1. **Login** to Filament admin
+2. **Navigate** to Policies list
+3. **Select** Settings Catalog policy
+4. **Verify** Settings tab active by default
+5. **Scroll** through grouped settings
+6. **Expand/Collapse** accordion groups
+7. **Hover** over truncated values (tooltips)
+8. **Click** copy buttons
+9. **Use** search filter
+10. **Switch** to JSON tab
