+# Plan: Delete Anime Feature
+
+## Feature Summary
+Add a right-click context menu option on anime series cards to delete an anime. Provides three deletion modes: database-only, folder-only, or both. Requires the user to type "delete" in a confirmation field.
+
+---
+
+## 1. Backend — Database Layer
+
+### 1.1 `src/server/database/service.py` — Add `delete` method to `AnimeSeriesService`
+
+```python
+@staticmethod
+async def delete(db: AsyncSession, series_id: int) -> bool:
+    """Hard-delete an anime series and all its episodes/queue items.
+
+    Uses cascade delete configured on the AnimeSeries model
+    (cascade="all, delete-orphan" on episodes and download_items).
+
+    Args:
+        db: Database session
+        series_id: Primary key (id) of the AnimeSeries to delete
+
+    Returns:
+        True if a row was deleted, False if not found
+
+    Raises:
+        AnimeServiceError: On database errors
+    """
+```
+
+**Implementation notes:**
+- Uses `select(delete(...).where(...))` pattern matching existing codebase style
+- Logs series key + name before deletion for audit trail
+- Returns `True`/`False` (not an exception) when series not found — caller decides response code
+- Wraps in try/except, logs error, re-raises as `AnimeServiceError`
+
+### 1.2 `src/server/database/service.py` — Add `get_folder_path` helper to `AnimeSeriesService`
+
+```python
+@staticmethod
+async def get_folder_path(db: AsyncSession, series_key: str) -> str | None:
+    """Get the filesystem folder path for a series by its key.
+
+    Args:
+        db: Database session
+        series_key: Provider key (e.g. "attack-on-titan")
+
+    Returns:
+        Folder path string, or None if series not found
+    """
+```
+
+---
+
+## 2. Backend — AnimeService
+
+### 2.1 `src/server/services/anime_service.py` — Add `delete_series` method
+
+```python
+async def delete_series(
+    self,
+    key: str,
+    delete_database: bool = True,
+    delete_folder: bool = False,
+) -> DeleteSeriesResult:
+    """Delete an anime series from DB, filesystem, or both.
+
+    Args:
+        key: Series key (primary identifier)
+        delete_database: If True, remove from database (default True)
+        delete_folder: If True, remove folder from filesystem (default False)
+
+    Returns:
+        DeleteSeriesResult with success status, what was deleted, errors
+
+    Raises:
+        AnimeServiceError: On critical failures
+    """
+```
+
+**`DeleteSeriesResult` Pydantic model (add to `src/server/models/anime.py`):**
+
+```python
+class DeleteSeriesResult(BaseModel):
+    success: bool
+    key: str
+    name: str
+    deleted_from_database: bool
+    deleted_folder: bool
+    folder_path: str | None
+    database_error: str | None
+    folder_error: str | None
+    message: str
+```
+
+**Step-by-step inside `delete_series`:**
+
+1. **Log start** — `logger.info("Delete series requested key=%s db=%s folder=%s", key, delete_database, delete_folder)`
+2. **Fetch series from DB** to get `id`, `folder`, `name`
+3. **If `delete_database=True`**:
+   a. Call `AnimeSeriesService.delete(db, series_id)`
+   b. Log success/failure
+   c. Invalidate `_cached_list_missing` LRU cache
+   d. Broadcast `series_deleted` WebSocket event
+4. **If `delete_folder=True`**:
+   a. Validate folder path with `is_safe_path(self._directory, folder_path)` — reject if outside base directory
+   b. Use `shutil.rmtree(folder_path)` to delete the folder
+   c. Log success/failure
+5. **Log completion** — `logger.info("Delete series completed key=%s results=%s", key, result)`
+6. Return `DeleteSeriesResult`
+
+**Error handling:**
+- DB errors during folder delete → log but don't fail the whole operation
+- Folder delete errors → log, attach to result, don't rollback DB delete
+- Series not found → return `DeleteSeriesResult(success=False, message="Series not found")`
+
+### 2.2 `src/server/services/anime_service.py` — Add `broadcast_series_deleted`
+
+```python
+async def _broadcast_series_deleted(self, key: str, name: str) -> None:
+    """Broadcast series_deleted event via WebSocket."""
+```
+
+Mirrors existing `_broadcast_series_updated` pattern.
+
+---
+
+## 3. Backend — API Layer
+
+### 3.1 `src/server/api/anime.py` — Add request/response models
+
+```python
+class DeleteSeriesRequest(BaseModel):
+    """Request payload for DELETE /api/anime/{key}."""
+    delete_database: bool = Field(
+        default=True,
+        description="Whether to remove the series from the database"
+    )
+    delete_folder: bool = Field(
+        default=False,
+        description="Whether to delete the series folder from filesystem"
+    )
+    confirm_text: str = Field(
+        ...,
+        description="Must be exactly 'delete' to confirm"
+    )
+
+class DeleteSeriesResponse(BaseModel):
+    """Response payload for DELETE /api/anime/{key}."""
+    success: bool
+    key: str
+    name: str
+    deleted_from_database: bool
+    deleted_folder: bool
+    folder_path: str | None
+    database_error: str | None
+    folder_error: str | None
+    message: str
+```
+
+### 3.2 `src/server/api/anime.py` — Add DELETE endpoint
+
+```python
+@router.delete("/{key}", response_model=DeleteSeriesResponse)
+async def delete_anime(
+    key: str,
+    request: DeleteSeriesRequest,
+    _auth: dict = Depends(require_auth),
+    anime_service: AnimeService = Depends(get_anime_service),
+) -> DeleteSeriesResponse:
+    """Delete an anime series from database, filesystem, or both.
+
+    Requires typing 'delete' in the confirm_text field to prevent accidents.
+
+    Args:
+        key: Series key (from URL path)
+        request: DeleteSeriesRequest with options and confirmation
+        _auth: Ensures the caller is authenticated
+        anime_service: AnimeService instance
+
+    Returns:
+        DeleteSeriesResponse with outcome details
+
+    Raises:
+        HTTPException(400): If confirm_text is not exactly 'delete'
+        HTTPException(404): If series not found
+        HTTPException(500): On unexpected errors
+    """
+```
+
+**Validation:**
+- `confirm_text` must be exactly `"delete"` (case-insensitive? No — exact match to be strict)
+- If `delete_folder=True` but folder doesn't exist → log warning, continue with DB delete
+- If neither `delete_database` nor `delete_folder` is True → return 400
+
+### 3.3 Update constants — No changes needed to `constants.js` for the endpoint path
+
+The existing `API.ANIME_LIST` pattern is `/api/anime` — DELETE `/api/anime/{key}` follows REST conventions.
+
+---
+
+## 4. Frontend — Context Menu
+
+### 4.1 `src/server/web/static/js/index/context-menu.js` — Add delete option
+
+```javascript
+// In the show() function, add a divider and delete option:
+menuElement.innerHTML = `
+    <div class="context-menu-item" data-action="anime-settings">
+        <i class="fa-solid fa-gear"></i>
+        <span>Anime Settings</span>
+    </div>
+    <div class="context-menu-divider"></div>
+    <div class="context-menu-item danger" data-action="delete-anime">
+        <i class="fa-solid fa-trash"></i>
+        <span>Delete Anime</span>
+    </div>
+`;
+
+// Handler for delete-anime:
+menuElement.querySelector('[data-action="delete-anime"]').addEventListener('click', function() {
+    const key = currentSeriesKey;
+    hide();
+    AniWorld.DeleteModal && AniWorld.DeleteModal.show(key);
+});
+```
+
+### 4.2 Create `src/server/web/static/js/index/delete-modal.js`
+
+New module for the confirmation modal. Module structure mirrors `anime-settings.js`.
+
+**Features:**
+- `show(key)` — opens modal with series info populated
+- `hide()` — closes and resets modal
+- Shows series name and key being deleted
+- Three checkboxes: `☐ Remove from database` (default checked), `☐ Delete folder` (default unchecked)
+- Confirmation text field: user must type exactly `delete`
+- Delete button: disabled until confirmation text matches
+- Error display area
+- Keyboard: Escape closes, Enter submits if valid
+
+**Modal HTML structure** (inline in JS, no new HTML file needed):
+
+```html
+<div id="delete-modal" class="modal hidden">
+  <div class="modal-backdrop"></div>
+  <div class="modal-content">
+    <h2>Delete Anime</h2>
+    <p id="delete-modal-series-name"></p>
+    <p id="delete-modal-series-key"></p>
+
+    <label>
+      <input type="checkbox" id="delete-db-checkbox" checked>
+      Remove from database (recommended)
+    </label>
+    <label>
+      <input type="checkbox" id="delete-folder-checkbox">
+      Delete folder from filesystem
+    </label>
+    <p class="warning">This will permanently delete the folder and all its files!</p>
+
+    <label for="delete-confirm-input">
+      Type <strong>delete</strong> to confirm:
+    </label>
+    <input type="text" id="delete-confirm-input" placeholder="delete">
+
+    <div id="delete-error" class="error-message hidden"></div>
+
+    <div class="modal-actions">
+      <button id="delete-cancel-btn">Cancel</button>
+      <button id="delete-confirm-btn" disabled>Delete</button>
+    </div>
+  </div>
+</div>
+```
+
+**CSS** — add to existing CSS files:
+- `.context-menu-item.danger { color: var(--color-danger, #dc3545); }`
+- `.context-menu-divider { height: 1px; background: var(--color-border); margin: 4px 0; }`
+- `.warning { color: var(--color-warning, #ffc107); font-size: 0.875em; }`
+- Modal styles (`.modal`, `.modal-backdrop`, `.modal-content`) — reuse existing modal CSS if present, or add new
+
+**API call on confirm:**
+```javascript
+const response = await AniWorld.ApiClient.request(`/api/anime/${encodeURIComponent(key)}`, {
+    method: 'DELETE',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify({
+        delete_database: document.getElementById('delete-db-checkbox').checked,
+        delete_folder: document.getElementById('delete-folder-checkbox').checked,
+        confirm_text: document.getElementById('delete-confirm-input').value
+    })
+});
+```
+
+**On success:**
+- Show success toast
+- Close modal
+- Reload series grid (or remove card from DOM directly)
+
+**On error:**
+- Show error message in modal
+
+### 4.3 `src/server/web/static/js/index/app-init.js` — Initialize delete modal
+
+Add initialization call:
+```javascript
+if (AniWorld.DeleteModal) {
+    AniWorld.DeleteModal.init();
+}
+```
+
+---
+
+## 5. WebSocket Event
+
+### 5.1 `src/server/services/websocket_service.py` — Add `broadcast_series_deleted`
+
+```python
+async def broadcast_series_deleted(self, key: str, name: str) -> None:
+    """Broadcast a series_deleted event.
+
+    Args:
+        key: Series key that was deleted
+        name: Series name for display
+    """
+```
+
+### 5.2 `src/server/web/static/js/index/socket-handler.js` — Handle `series_deleted`
+
+Handle the new WebSocket event to remove the deleted card from the UI in real-time:
+
+```javascript
+case AniWorld.Constants.WS_EVENTS.SERIES_DELETED:
+    if (AniWorld.SeriesManager) {
+        AniWorld.SeriesManager.removeSeries(data.key);
+    }
+    break;
+```
+
+### 5.3 `src/server/web/static/js/shared/constants.js` — Add event constant
+
+```javascript
+SERIES_DELETED: 'series_deleted',
+```
+
+---
+
+## 6. Logging
+
+### 6.1 Backend logging points (all use Python `logging.getLogger(__name__)`):
+
+| Event | Level | Message format |
+|-------|-------|----------------|
+| Delete requested | `info` | `"Delete series requested: key=%s delete_database=%s delete_folder=%s"` |
+| Series not found | `warning` | `"Delete series failed - not found: key=%s"` |
+| DB delete success | `info` | `"Deleted series from database: key=%s name=%s id=%d"` |
+| DB delete failure | `error` | `"Failed to delete series from database: key=%s error=%s"` |
+| Folder delete start | `info` | `"Deleting series folder: key=%s path=%s"` |
+| Folder delete success | `info` | `"Deleted series folder: key=%s path=%s"` |
+| Folder delete failure | `error` | `"Failed to delete series folder: key=%s path=%s error=%s"` |
+| Path traversal blocked | `warning` | `"Blocked unsafe folder delete attempt: key=%s path=%s base=%s"` |
+| Delete completed | `info` | `"Delete series completed: key=%s db=%s folder=%s"` |
+
+### 6.2 Frontend logging points (console.log / console.error):
+
+| Event | Level |
+|-------|-------|
+| Delete modal opened | `console.info` |
+| Delete API call initiated | `console.info` |
+| Delete success | `console.info` |
+| Delete API error | `console.error` |
+| Validation failure (confirm_text) | `console.warn` |
+
+---
+
+## 7. Documentation
+
+### 7.1 Create `docs/delete-anime-feature.md`
+
+```markdown
+# Delete Anime Feature
+
+## Overview
+Allows authenticated users to delete an anime series from the database, 
+filesystem, or both via the right-click context menu on series cards.
+
+## Safety Mechanisms
+
+### Confirmation Required
+Users must type exactly `delete` in a confirmation field before deletion
+proceeds. This prevents accidental clicks.
+
+### Selective Deletion
+Two independent options:
+- **Remove from database**: Removes the series and all its episodes/queue 
+  items from the SQLite database. The folder on disk is preserved.
+- **Delete folder**: Removes the series folder and ALL files inside it 
+  from the filesystem. This cannot be undone.
+
+### Path Traversal Protection
+Folder deletion validates the target path is within the configured 
+`directory_to_search` base directory before attempting deletion.
+
+## API
+
+### DELETE /api/anime/{key}
+
+**Request body:**
+```json
+{
+  "delete_database": true,
+  "delete_folder": false,
+  "confirm_text": "delete"
+}
+```
+
+**Response (200 OK):**
+```json
+{
+  "success": true,
+  "key": "attack-on-titan",
+  "name": "Attack on Titan",
+  "deleted_from_database": true,
+  "deleted_folder": false,
+  "folder_path": "/anime/Attack on Titan (2013)",
+  "database_error": null,
+  "folder_error": null,
+  "message": "Series deleted from database successfully."
+}
+```
+
+**Error responses:**
+- `400 Bad Request`: confirm_text != "delete", or neither delete option selected
+- `401 Unauthorized`: Missing or invalid auth token
+- `404 Not Found`: Series key does not exist
+- `500 Internal Server Error`: Unexpected error
+
+## Events
+
+### WebSocket: series_deleted
+Broadcast to all connected clients when a series is deleted.
+
+**Payload:**
+```json
+{
+  "event": "series_deleted",
+  "key": "attack-on-titan",
+  "name": "Attack on Titan"
+}
+```
+
+## Permissions
+Requires authentication. Only authenticated users can delete anime.
+```
+
+---
+
+## 8. Tests
+
+### 8.1 Unit Tests — `tests/unit/test_anime_service.py`
+
+Add new test class:
+
+```python
+class TestDeleteSeries:
+    """Test delete_series operation."""
+
+    @pytest.mark.asyncio
+    async def test_delete_database_only_success(self, anime_service, mock_series_app):

+```
+
+### 8.2 API Endpoint Tests — `tests/api/test_anime_endpoints.py`
+
+Add tests for `DELETE /api/anime/{key}`:
+
+```python
+class TestDeleteAnimeEndpoints:
+    """Tests for DELETE /api/anime/{key}."""

+        """Test that path traversal is blocked."""
+```
+
+### 8.3 Frontend Tests — `tests/frontend/test_existing_ui_integration.py`
+
+Add integration tests for delete modal:
+
+```javascript
+describe('Delete Anime Modal', () => {
+    it('should open on context menu delete click');
+    it('should require typing delete to enable button');
+    it('should call DELETE API on confirm');
+    it('should show error on API failure');
+    it('should close on cancel');
+    it('should close on Escape key');
+    it('should disable confirm until text matches');
+});
+```
+
+### 8.4 Security Tests — `tests/security/test_input_validation.py`
+
+```python
+class TestDeleteValidation:
+    """Security tests for delete endpoint input validation."""
+
+    def test_path_traversal_in_folder_delete(self, client, auth_headers):

+### DELETE /api/anime/{anime_key}
+
+Delete an anime series from the database, filesystem, or both. Requires
+authentication and explicit typed confirmation.
+
+**Authentication:** Required
+
+**Path Parameters:**
+| Parameter | Description |
+|-----------|-------------|
+| `anime_key` | Series key (primary identifier) |
+
+**Request Body:**
+```json
+{
+    "delete_database": true,
+    "delete_folder": false,
+    "confirm_text": "delete"
+}
+```
+
+| Field | Type | Default | Description |
+|-------|------|---------|-------------|
+| `delete_database` | bool | `true` | Remove series and episodes from SQLite |
+| `delete_folder` | bool | `false` | Delete the series folder and all files |
+| `confirm_text` | string | — | Must be exactly `"delete"` (case-sensitive) |
+
+**Response (200 OK):**
+```json
+{
+    "success": true,
+    "key": "attack-on-titan",
+    "name": "Attack on Titan",
+    "deleted_from_database": true,
+    "deleted_folder": false,
+    "folder_path": null,
+    "database_error": null,
+    "folder_error": null,
+    "message": "Removed from database."
+}
+```
+
+**Error Responses:**
+
+| Status | Condition |
+|--------|-----------|
+| 400 | `confirm_text != "delete"` or neither flag is `true` |
+| 401 | Not authenticated |
+| 404 | Series `key` not found in database |
+| 500 | Unexpected server error |
+
+**Deletion Modes:**
+
+| Flags | Effect |
+|-------|--------|
+| `delete_database=true, delete_folder=false` | Removes series from SQLite. Folder on disk is preserved. |
+| `delete_database=false, delete_folder=true` | Deletes folder and all files. Database record preserved. |
+| `delete_database=true, delete_folder=true` | Full removal: database record deleted AND folder/files deleted. |
+
+**Path Safety:** Folder deletion is blocked if the path is outside the configured anime base directory (path traversal protection via `is_safe_path`).
+
+**WebSocket Broadcast:** On success, a `series_deleted` event is broadcast to all connected clients, causing the anime card to be removed from all browser sessions in real-time.

+# Delete Anime Feature
+
+## Overview
+
+The Delete Anime feature allows authenticated users to remove an anime series from the Aniworld library. It supports three deletion modes: **database only**, **folder only**, or **both**. A mandatory typed-confirmation (`delete`) prevents accidental deletions.
+
+---
+
+## Usage
+
+### How to Delete an Anime
+
+1. **Right-click** on any anime series card in the library grid.
+2. Select **"Delete Anime"** from the context menu.
+3. A confirmation modal appears with two options:
+   - ☑️ **Remove from database** (recommended) — removes series and episodes from SQLite
+   - ☐ **Delete folder from filesystem** — deletes the folder and all files inside
+4. **Type `delete`** in the confirmation text field to enable the Delete button.
+5. Click **Delete** to proceed.
+
+### What Gets Deleted
+
+| Option | Effect |
+|--------|--------|
+| Database only | Series, episodes, and queue entries removed from SQLite. Folder on disk is preserved. Downloaded episode files remain. |
+| Folder only | Entire folder and all files inside deleted from filesystem. Database record preserved with `is_downloaded=True`. |
+| Both | Full removal: database record deleted AND folder/files deleted from disk. |
+
+---
+
+## Architecture
+
+### Backend Components
+
+| File | Role |
+|------|------|
+| `src/server/api/anime.py` | `DELETE /api/anime/{key}` endpoint |
+| `src/server/services/anime_service.py` | `AnimeService.delete_series()` orchestrator |
+| `src/server/services/websocket_service.py` | `broadcast_series_deleted()` for real-time UI updates |
+| `src/server/database/service.py` | `AnimeSeriesService.get_folder_path()` + existing `delete()` |
+| `src/server/models/anime.py` | `DeleteSeriesRequest` / `DeleteSeriesResult` Pydantic models |
+
+### Frontend Components
+
+| File | Role |
+|------|------|
+| `src/server/web/static/js/index/delete-modal.js` | Modal UI, confirm text validation, API calls |
+| `src/server/web/static/js/index/context-menu.js` | Right-click "Delete Anime" menu item |
+| `src/server/web/static/js/index/socket-handler.js` | `SERIES_DELETED` WebSocket event handler |
+| `src/server/web/static/js/index/series-manager.js` | `removeSeries(key)` — removes card from grid |
+| `src/server/web/static/js/index/app-init.js` | Initializes `DeleteModal` |
+| `src/server/web/static/css/components/modals.css` | Modal and context menu styles |
+| `src/server/web/templates/index.html` | Loads `delete-modal.js` before `app-init.js` |
+
+### API Endpoint
+
+```
+DELETE /api/anime/{key}
+```
+
+**Request body:**
+```json
+{
+    "delete_database": true,
+    "delete_folder": false,
+    "confirm_text": "delete"
+}
+```
+
+**Success response (200):**
+```json
+{
+    "success": true,
+    "key": "attack-on-titan",
+    "name": "Attack on Titan",
+    "deleted_from_database": true,
+    "deleted_folder": false,
+    "folder_path": null,
+    "database_error": null,
+    "folder_error": null,
+    "message": "Removed from database."
+}
+```
+
+**Error responses:**
+| Status | Condition |
+|--------|-----------|
+| 400 | `confirm_text != "delete"` or neither flag is `true` |
+| 401 | Not authenticated |
+| 404 | Series `key` not found in database |
+| 500 | Unexpected server error |
+
+### WebSocket Event
+
+After a successful delete, the server broadcasts a `series_deleted` event:
+
+```json
+{
+    "type": "series_deleted",
+    "data": {
+        "key": "attack-on-titan",
+        "name": "Attack on Titan"
+    }
+}
+```
+
+All connected clients remove the card from their grid in real-time.
+
+---
+
+## Safety Mechanisms
+
+### 1. Typed Confirmation
+Users must type exactly `delete` (case-sensitive) to unlock the Delete button. This prevents accidental clicks from triggering deletion.
+
+### 2. Path Traversal Protection
+Before deleting a folder, `is_safe_path()` validates the path stays within the configured anime base directory. Paths outside this boundary are rejected with a `folder_error`.
+
+### 3. Granular Options
+The two independent checkboxes ensure users consciously choose what to delete. Default is **database only** (recommended).
+
+### 4. WebSocket Broadcast
+All clients are notified immediately when a series is deleted, keeping multiple browser sessions in sync.
+
+### 5. No Shell Injection
+Series keys are never passed to shell commands. All file operations use `pathlib.Path`.

+## Logging
+
+### Backend Logs (Python/`logging`)
+
+| Event | Level | Message |
+|-------|-------|---------|
+| Delete initiated | INFO | `Delete anime initiated: key={key} delete_db={x} delete_folder={x}` |
+| Series not found | WARNING | `Delete anime failed — series not found: key={key}` |

+| Folder delete error | ERROR | `Delete anime folder error: key={key} error={message}` |
+| Delete succeeded | INFO | `Delete anime succeeded: key={key} deleted_db={x} deleted_folder={x}` |
+
+### Frontend Logs (JS/`console`)
+
+| Event | Method |
+|-------|--------|
+| Modal opened | `console.info('[DeleteModal] Opening for key:', key)` |
+| Delete confirmed | `console.info('[DeleteModal] Initiating delete:', {...})` |
+| Delete succeeded | `console.info('[DeleteModal] Delete succeeded:', result)` |
+| API/network error | `console.error('[DeleteModal] Delete request failed:', err)` |
+| Series removed from grid | `console.info('[SeriesManager] Removed series from local state:', key)` |
+| WS event received | `console.info('[SocketHandler] Series deleted:', data)` |
+
+---
+
+## Configuration
+
+No new configuration options are required. The feature uses existing paths:
+- **Anime base directory**: `settings.anime_directory` (for path traversal validation)
+- **Database path**: `series_app.database_path` (for DB deletion)
+- **Queue cleanup**: `AnimeSeriesService.delete(series_key)` cascades to queue items
+
+---
+
+## Testing
+
+See:
+- `tests/unit/test_delete_anime_service.py` — unit tests for `AnimeService.delete_series()`
+- `tests/api/test_delete_anime_endpoint.py` — API endpoint tests including auth, validation, error cases
+- `tests/frontend/test_delete_modal.py` — frontend modal logic and DOM validation tests
+- `tests/security/test_delete_anime_security.py` — security tests for path traversal, XSS, auth bypass
