Subject: [PATCH] test(api): add Bruno API collection for saved filters
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add comprehensive Bruno OpenCollection YAML files for testing
the saved filters API with 9 request files and scenarios.

Main CRUD Requests (4 files):
1. List Saved Filters.yml
   - GET /api/saved-filters?resource_type=media-items
   - Documents resource_type parameter requirement
   - Example responses with JSONB filters

2. Create Saved Filter.yml
   - POST /api/saved-filters
   - Complete request body documentation
   - All filter field examples (genre, author, sort, year, etc.)
   - Validation rules (max 100 chars, uniqueness)

3. Update Saved Filter.yml
   - PUT /api/saved-filters/{filter_id}
   - Immutability notes (resource_type can't change)
   - Duplicate name validation
   - Updated timestamp behavior

4. Delete Saved Filter.yml
   - DELETE /api/saved-filters/{filter_id}
   - 204 No Content response
   - Security considerations

Scenario Test Files (5 files):

1. Duplicate Name Validation.yml
   - Tests 409 Conflict on duplicate names
   - Per-user + per-resource-type uniqueness
   - Example bash test script

2. User Isolation - Cross-User Access.yml
   - Tests users can't access each other's filters
   - Security: 404 instead of 403 (prevents enumeration)
   - Complete multi-user test scenario
   - Database-level isolation documentation

3. Multiple Resource Types.yml
   - Tests generic design with different resource types
   - Same name allowed for different types (media-items, collections, devices)
   - Examples for each resource type
   - Extensibility benefits explained

4. Complete CRUD Workflow.yml
   - End-to-end lifecycle test (6.5K file)
   - Shell script with all steps: Create → Read → Update → Delete → Verify
   - Success criteria checklist
   - Copy-paste ready test script

5. Filter Validation - Edge Cases.yml
   - 12 different validation test cases
   - Empty names, missing fields, invalid UUIDs
   - Unicode support (emoji, CJK characters)
   - Malformed JSON handling
   - Special characters and XSS attempts

Documentation Features:
- {{base_url}} variable substitution
- auth: inherit for authentication
- Comprehensive docs: sections with examples
- Shell commands ready to copy-paste
- Expected status codes and responses
- Error handling examples
- Security best practices

Total: 9 YAML files covering all CRUD operations and edge cases

Usage:
- Import into Bruno/Postman for API testing
- Use for manual testing during development
- Reference for API contract validation
- Example curl commands for documentation

+  - 401: Unauthorized - Invalid or missing authentication token
+  - 404: Not Found - Filter doesn't exist or doesn't belong to user
+  - 500: Internal Server Error - Database error
+
+  **Example Usage:**
+  ```bash
+  curl -X DELETE \
+    -H "Authorization: Bearer YOUR_TOKEN" \
+    "{{base_url}}/api/saved-filters/{{filter_id}}"
+  ```
+
+  **Important Notes:**
+  - You can only delete filters that belong to you
+  - Deletion is permanent - cannot be undone
+  - Returns 204 No Content on success (no response body)
+  - If filter doesn't exist or belongs to another user, returns 404
+
+  **Error Response Examples:**
+
+  Invalid filter ID:
+  ```json
+  {
+    "error": "invalid filter ID"
+  }
+  ```
+
+  Filter not found:

+  {
+    "error": "failed to delete filter"
+  }
+  ```
+
+  **Testing Deletion:**
+  ```bash
+  # First, create a filter
+  CREATE_RESPONSE=$(curl -s -X POST \
+    -H "Authorization: Bearer YOUR_TOKEN" \
+    -H "Content-Type: application/json" \
+    -d '{
+      "name": "To Be Deleted",
+      "resource_type": "media-items",
+      "filters": {}
+    }' \
+    "{{base_url}}/api/saved-filters")
+
+  # Extract the ID
+  FILTER_ID=$(echo $CREATE_RESPONSE | jq -r '.id')
+
+  # Delete the filter
+  curl -X DELETE \
+    -H "Authorization: Bearer YOUR_TOKEN" \
+    "{{base_url}}/api/saved-filters/$FILTER_ID"
+
+  # Verify it's gone
+  curl -H "Authorization: Bearer YOUR_TOKEN" \
+    "{{base_url}}/api/saved-filters?resource_type=media-items"
+  ```
+
+  **Cascade Effects:**
+  - No cascade effects - saved filters are standalone records
+  - User deletion automatically cascades to delete their filters
+  - No foreign key dependencies on other tables

+  - You can only update filters that belong to you
+  - The `updated_at` timestamp is automatically updated
+  - Cannot change the resource_type (it's immutable)
+  - New name must not conflict with other filters you own for the same resource type
+  - All filter fields are replaced entirely (partial updates not supported)

+  ## Duplicate Name Validation
+
+  Tests that the API correctly prevents creating duplicate filter names for the same user + resource type combination.
+
+  **Scenario:**
+  1. Create first filter with name "Duplicate Test"
+  2. Attempt to create second filter with same name
+  3. Expect 409 Conflict error
+
+  **Expected Behavior:**
+  - First request: 201 Created
+  - Second request: 409 Conflict with error message
+
+  **Error Response:**
+  ```json
+  {
+    "error": "filter with name 'Duplicate Test' already exists for this resource type"
+  }
+  ```
+
+  **Test Steps:**
+  ```bash
+  # First request - should succeed
+  curl -X POST \
+    -H "Authorization: Bearer YOUR_TOKEN" \
+    -H "Content-Type: application/json" \
+    -d '{
+      "name": "Duplicate Test",
+      "resource_type": "media-items",
+      "filters": {"search": "test"}
+    }' \
+    "{{base_url}}/api/saved-filters"
+
+  # Response: 201 Created
+
+  # Second request - should fail with 409
+  curl -X POST \
+    -H "Authorization: Bearer YOUR_TOKEN" \
+    -H "Content-Type: application/json" \
+    -d '{
+      "name": "Duplicate Test",
+      "resource_type": "media-items",
+      "filters": {"search": "test"}
+    }' \
+    "{{base_url}}/api/saved-filters"
+
+  # Response: 409 Conflict
+  # {
+  #   "error": "filter with name 'Duplicate Test' already exists for this resource type"
+  # }
+  ```
+
+  **Important Notes:**
+  - Duplicate check is per user + resource type
+  - Same filter name can be used for different resource types
+  - Different users can have filters with the same name
+  - Validation happens in service layer before database insertion
+
+  **Related Tests:**
+  - Update filter with name that conflicts with another filter (should also return 409)
+  - Create filter with different name for different resource type (should succeed)

+  ## Multiple Resource Types
+
+  Tests that the saved filters system works correctly with different resource types (media-items, collections, devices, etc.).

+  3. Test that same filter name can exist for different resource types

+  **Step 1: Create filters for different resource types**
+  ```bash
+  # Create filter for media-items
+  curl -X POST \
+    -H "Authorization: Bearer YOUR_TOKEN" \
+    -H "Content-Type: application/json" \

+      "filters": {"device_type": "ereader"}
+    }' \
+    "{{base_url}}/api/saved-filters"
+  ```
+
+  **Step 2: List filters by resource type**
+  ```bash
+  # Get only media-items filters
+  curl -H "Authorization: Bearer YOUR_TOKEN" \
+    "{{base_url}}/api/saved-filters?resource_type=media-items"
+
+  # Expected response:
+  # [
+  #   {
+  #     "id": "...",
+  #     "name": "My Favorites",
+  #     "resource_type": "media-items",
+  #     "filters": {"genre_filter": "Science Fiction"},
+  #     ...
+  #   }
+  # ]
+
+  # Get only collections filters
+  curl -H "Authorization: Bearer YOUR_TOKEN" \
+    "{{base_url}}/api/saved-filters?resource_type=collections"
+
+  # Expected response:
+  # [
+  #   {
+  #     "id": "...",
+  #     "name": "My Favorites",
+  #     "resource_type": "collections",
+  #     "filters": {"sort_by": "name"},
+  #     ...
+  #   }
+  # ]
+
+  # Get only devices filters
+  curl -H "Authorization: Bearer YOUR_TOKEN" \
+    "{{base_url}}/api/saved-filters?resource_type=devices"
+
+  # Expected response:
+  # [
+  #   {
+  #     "id": "...",
+  #     "name": "My Favorites",
+  #     "resource_type": "devices",
+  #     "filters": {"device_type": "ereader"},
+  #     ...
+  #   }
+  # ]
+  ```
+
+  **Expected Behavior:**
+  - Same filter name allowed for different resource types
+  - Each resource_type query returns only that type's filters
+  - resource_type parameter is REQUIRED (no "get all" endpoint)
+  - Missing resource_type returns 400 Bad Request
+
+  **Validation:**
+  ```bash
+  # Test missing resource_type parameter
+  curl -H "Authorization: Bearer YOUR_TOKEN" \
+    "{{base_url}}/api/saved-filters"
+
+  # Expected: 400 Bad Request
+  # {
+  #   "error": "resource_type query parameter is required"
+  # }
+  ```
+
+  **Use Cases:**
+  - **media-items**: Filter books by genre, author, series, etc.
+  - **collections**: Filter collections by name, book count, etc.
+  - **devices**: Filter devices by type, sync status, etc.
+  - **Extensible**: New resource types can be added without schema changes
+
+  **Filter Structure by Resource Type:**
+
+  **Media Items Filter Fields:**
+  ```json
+  {
+    "search": "keyword",
+    "author_filter": "Author Name",
+    "genre_filter": "Science Fiction",
+    "series_filter": "Series Name",
+    "language_filter": "en",
+    "year_min": "2000",
+    "year_max": "2024",
+    "sort": "title ASC"
+  }
+  ```
+
+  **Collections Filter Fields:**
+  ```json
+  {
+    "sort_by": "name",
+    "order": "asc",
+    "include_auto": "true"
+  }
+  ```
+
+  **Devices Filter Fields:**
+  ```json
+  {
+    "device_type": "ereader",
+    "sync_enabled": "true",
+    "sort": "last_sync DESC"
+  }
+  ```
+
+  **Benefits of Generic Design:**
+  - Single endpoint handles all resource types
+  - No need for separate endpoints per resource
+  - Flexible JSONB storage allows any filter structure
+  - Easy to add new resource types in future

+  ## User Isolation - Cross-User Access
+
+  Tests that users cannot access or modify filters created by other users.
+
+  **Scenario:**
+  1. User A creates a filter
+  2. User B attempts to delete User A's filter
+  3. Expect 404 Not Found (user isolation)
+
+  **Expected Behavior:**
+  - User A can CRUD their own filters
+  - User B cannot access User A's filters
+  - API returns 404 (not 403) for security (doesn't reveal filter existence)
+
+  **Test Setup:**
+  ```bash
+  # Step 1: Create regular user (User A)
+  USER_A_EMAIL="usera@test.com"
+  USER_A_PASS="password123"
+  
+  # Create user and get token
+  USER_A_TOKEN=$(curl -s -X POST \
+    -H "Content-Type: application/json" \
+    -d "{
+      \"email\": \"$USER_A_EMAIL\",
+      \"username\": \"usera\",
+      \"password\": \"$USER_A_PASS\",
+      \"first_name\": \"User\",
+      \"last_name\": \"A\"
+    }" \
+    "{{base_url}}/api/auth/register" | jq -r '.token')
+
+  # Step 2: User A creates a filter
+  FILTER_RESPONSE=$(curl -s -X POST \
+    -H "Authorization: Bearer $USER_A_TOKEN" \
+    -H "Content-Type: application/json" \
+    -d '{
+      "name": "User A Private Filter",
+      "resource_type": "media-items",
+      "filters": {"search": "private"}
+    }' \
+    "{{base_url}}/api/saved-filters")
+
+  FILTER_ID=$(echo $FILTER_RESPONSE | jq -r '.id')
+  
+  echo "User A created filter: $FILTER_ID"
+  ```
+
+  **Test Steps:**
+  ```bash
+  # Step 3: Admin user attempts to delete User A's filter
+  curl -X DELETE \
+    -H "Authorization: Bearer {{admin_token}}" \
+    "{{base_url}}/api/saved-filters/$FILTER_ID"
+
+  # Expected Response: 404 Not Found
+  # {
+  #   "error": "failed to delete filter"
+  # }
+  ```
+
+  **Expected Status Codes:**
+  - 404: Not Found (filter doesn't exist OR doesn't belong to user)
+  - NOT 403: Forbidden (we don't reveal whether filter exists)
+
+  **Security Considerations:**
+  - Never reveal whether a filter ID exists for another user
+  - Always return 404 for cross-user access attempts
+  - Prevents user enumeration attacks
+  - Each user sees only their own filters
+
+  **Additional Test Cases:**
+  
+  **Get Another User's Filter:**
+  ```bash
+  # User B tries to get User A's filter details
+  curl -H "Authorization: Bearer $USER_B_TOKEN" \
+    "{{base_url}}/api/saved-filters/$FILTER_ID"
+
+  # Expected: 404 Not Found
+  ```
+
+  **Update Another User's Filter:**
+  ```bash
+  # User B tries to update User A's filter
+  curl -X PUT \
+    -H "Authorization: Bearer $USER_B_TOKEN" \
+    -H "Content-Type: application/json" \
+    -d '{
+      "name": "Hacked Filter",
+      "resource_type": "media-items",
+      "filters": {}
+    }' \
+    "{{base_url}}/api/saved-filters/$FILTER_ID"
+
+  # Expected: 404 Not Found
+  ```
+
+  **List Only Own Filters:**
+  ```bash
+  # User A lists their filters
+  curl -H "Authorization: Bearer $USER_A_TOKEN" \
+    "{{base_url}}/api/saved-filters?resource_type=media-items"
+
+  # Expected: Only User A's filters returned
+
+  # User B lists filters for same resource type
+  curl -H "Authorization: Bearer $USER_B_TOKEN" \
+    "{{base_url}}/api/saved-filters?resource_type=media-items"
+
+  # Expected: Only User B's filters returned (different result)
+  ```
+
+  **Database-Level Isolation:**
+  - All queries include `WHERE user_id = @user_id` clause
+  - Service layer validates ownership before operations
+  - JWT token provides user_id for automatic scoping
