chore: bump version

Runs after NFO refresh during scheduled rescans. Renames folders that
are missing a year (e.g. 'Naruto' → 'Naruto (1999)') using the year
from the database record.

Safety: _build_target_folder() always strips any existing year suffix
first, preventing double/triple year accumulation like
'Naruto (1999) (1999) (1999)'.

Changes:
- New FolderNamingService (folder_naming_service.py) with safe target
  name construction, DB update, and in-memory cache update
- New SchedulerConfig field: folder_naming_after_nfo_scan (default True)
- Integrated as step 3 in scheduler _perform_rescan() after NFO scan
- Runtime UI: existing 'folder-scan-enabled' checkbox in index.html
  now wired to toggle the feature (app.js + scheduler-config.js)
- Setup screen: new checkbox in setup.html Scheduler Settings section
- API: scheduler config endpoint returns all scan toggles
- Tests: 39 unit tests covering static helpers, rename logic, safety
  guard, and integration cases (folder_naming_service.py)
- Docs: testing guide updated with FolderNamingService examples

+
+### Added
+
+- **Anime Settings page** — renamed from "NFO Diagnostics". Right-click
+  on any anime card → "Anime Settings" navigates to
+  `/anime/settings?key=<series>`. The new page lets the user view and
+  edit `name`, `folder`, `tmdb_id`, `tvdb_id`, and `site` directly in
+  the database, with options to rename the on-disk folder and
+  regenerate `tvshow.nfo` in one click.
+- **New API endpoints** under `/api/anime/{key}/`:
+    - `GET  /settings` — return full editable settings payload
+    - `PUT  /settings` — update fields with validation
+    - `POST /regenerate-nfo` — regenerate `tvshow.nfo` from TMDB
+- **Pydantic models**: `AnimeSettingsResponse`,
+  `AnimeSettingsUpdateRequest`, `AnimeSettingsRegenerateNfoResponse`
+  in [src/server/models/anime.py](../src/server/models/anime.py).
+- **Frontend module**: `AniWorld.AnimeSettingsManager` IIFE in
+  [src/server/web/static/js/pages/anime-settings.js](../src/server/web/static/js/pages/anime-settings.js)
+  with public API: `init`, `loadSeries`, `saveSettings`,
+  `regenerateNfo`, `validateField`, `populateForm`, `showSaveSuccess`,
+  `showError`.
+- **Vitest JS unit tests** covering every public function on
+  `AnimeSettingsManager` — 31 tests in
+  [tests/frontend/unit/anime_settings.test.js](../tests/frontend/unit/anime_settings.test.js).
+- **Playwright E2E test** for the right-click → settings page flow in
+  [tests/frontend/e2e/anime_settings_page.spec.js](../tests/frontend/e2e/anime_settings_page.spec.js).
+
+### Changed
+
+- **Right-click context menu** on the library page: "NFO Diagnostics"
+  → "Anime Settings" (`data-action="nfo-diagnostics"` →
+  `data-action="anime-settings"`).
+- **Configuration modal link**: "Open NFO Diagnostics" → "Open Anime
+  Settings", target URL `/settings/nfo` → `/anime/settings`.
+- **Page route**: `/settings/nfo` returns a 301 redirect to
+  `/anime/settings` for backwards compatibility with bookmarks.
+- **Pydantic model rename** in [src/server/models/nfo.py](../src/server/models/nfo.py):
+    - `NfoDiagnosticsResponse` → `NfoSettingsResponse`
+    - `NfoSeriesDiagnostics` → `NfoSeriesSettings`
+- **Function rename** in [src/server/api/nfo.py](../src/server/api/nfo.py):
+    - `get_nfo_diagnostics` → `get_nfo_settings`
+    - `repair_nfo` → `repair_nfo_settings`
+
+### Fixed
+
+- **Bug**: `src/server/api/nfo.py` called the non-existent
+  `anime_service.update_series_nfo_status(...)` method, which would
+  raise `AttributeError` after a successful NFO repair. Renamed the
+  call to the existing `update_nfo_status(...)` method (matching its
+  signature `(key, has_nfo, tmdb_id=None, tvdb_id=None, db=None)`)
+  and added an explicit `AnimeSeriesService.update(db, id, nfo_path=...)`
+  call to keep `nfo_path` in sync. Covered by regression tests in
+  `TestBugFixCreateOrUpdateNfo`.
+
+- **Bug**: Right-clicking a series card and choosing "Anime Settings"
+  opened `/anime/settings?key=null` instead of carrying the series key.
+  Root cause: the click handler in
+  [src/server/web/static/js/index/context-menu.js](../src/server/web/static/js/index/context-menu.js)
+  called `hide()` BEFORE building the URL — and `hide()` cleared
+  `currentSeriesKey` to null. Fix captures the key into a local
+  `const` before calling `hide()`. Regression-locked by
+  `tests/frontend/unit/context_menu.test.js` (5 tests).
+
+---
+
+## [Unreleased] - 2026-06-05
+
+### Fixed
+
+- **Folder scan series key resolution**: Fixed "Could not resolve series key for folder, skipping" warnings during library setup. `_resolve_key_via_search()` now uses fuzzy title matching instead of exact string comparison.
+    - Added `_normalize_title()` to strip anime suffixes: `(TV)`, `(Anime)`, `(OAD)`, `(OVA)`, `(Special)`, `(Movie)`, `(Spin-Off)`
+    - Added `_titles_match()` using `difflib.SequenceMatcher` with 0.85 similarity threshold for tolerance of minor title variations
+    - Added debug logging for title mismatches and multiple search results

+# Navigation & Redirect Logic
+
+This document describes the setup flow navigation, covering how users progress from initial setup through to the main application.
+
+## Overview
+
+The application uses a middleware-based redirect system to enforce a strict state machine. Users must complete each phase before accessing the next. Attempting to bypass the current phase redirects to the appropriate page.
+
+## State Machine
+

+
+## State Definitions
+
+| State | Condition | Target Page |
+|-------|-----------|-------------|
+| `NO_SETUP` | No master password configured | `/setup` |
+| `SETUP_COMPLETE` | Initial config passed, loading not started | `/loading` |
+| `UNRESOLVED_PENDING` | Setup done, unresolved exist, not marked done | `/setup/unresolved` |
+| `UNRESOLVED_DONE` | Unresolved phase marked complete, NFO scan pending | `/loading` |
+| `NFO_SCAN_PENDING` | Unresolved done, NFO scan incomplete | `/loading` |
+| `COMPLETE` | All phases finished | `/login` |
+
+## Middleware: SetupRedirectMiddleware
+
+**File:** `src/server/middleware/setup_redirect.py`
+
+The middleware intercepts all requests and enforces the state machine.
+
+### Exempt Paths (always accessible)
+
+| Path | Purpose |
+|------|---------|
+| `/setup` | Initial setup page |
+| `/setup/unresolved` | Unresolved folder resolution |
+| `/loading` | Initialization progress page |
+| `/login` | Authentication |
+| `/api/auth/*` | Auth endpoints |
+| `/api/config/*` | Config API |
+| `/api/health` | Health check |
+| `/static/*` | Static assets |
+
+### Middleware Logic
+
+The middleware checks the current state and redirects accordingly:
+
+```
+1. NO_SETUP state:
+   → Redirect ALL requests to /setup
+   → Exception: /setup itself is accessible
+
+2. SETUP_COMPLETE state:
+   → Redirect /setup to /loading
+   → Redirect any other page to /loading
+
+3. UNRESOLVED_PENDING state (unresolved folders exist, not marked done):
+   → Redirect /setup to /setup/unresolved
+   → Redirect /loading to /setup/unresolved
+   → Allow access to /setup/unresolved
+   → Redirect any other page to /setup/unresolved
+
+4. UNRESOLVED_DONE state (unresolved marked done, NFO scan pending):
+   → Redirect /setup to /loading
+   → Redirect /setup/unresolved to /loading
+   → Redirect any other page to /loading
+
+5. NFO_SCAN_PENDING state:
+   → Redirect /setup to /loading
+   → Redirect /setup/unresolved to /loading
+   → Allow access to /loading (NFO phase runs)
+   → Redirect any other page to /loading
+
+6. COMPLETE state (loading finished):
+   → Redirect /setup, /loading, /setup/unresolved to /login
+   → Allow access to /login and main app
+```
+
+### Phase Tracking Flags
+
+| Flag | Purpose |
+|------|---------|
+| `setup_complete` | Initial configuration was saved |
+| `loading_started` | Loading phase has been initiated (redirected to /loading) |
+| `unresolved_completed` | User clicked "Done" on unresolved page |
+| `loading_complete` | Series scan + initial loading finished |
+| `nfo_scan_complete` | Final NFO scan finished |
+
+## Pages
+
+### 1. Setup Page (`/setup`)
+
+**File:** `src/server/web/templates/setup.html`
+
+Handles initial configuration:
+- Master password creation
+- Anime directory selection
+- Database initialization
+
+**Allowed in states:** `NO_SETUP`
+
+**Post-completion:**
+- Sets `setup_complete` flag
+- Redirects to `/loading`
+
+### 2. Loading Page (`/loading`)
+
+**File:** `src/server/web/templates/loading.html`
+
+Shows initialization progress via WebSocket:
+- Series scanning
+- Database population
+- Logo/image loading
+
+**Allowed in states:** `SETUP_COMPLETE`, `UNRESOLVED_DONE`, `NFO_SCAN_PENDING`
+
+**Post-initialization (series scan complete):**
+```javascript
+async function checkUnresolvedAndProceed() {
+    const res = await fetch('/api/setup/unresolved', {
+        headers: { 'Authorization': `Bearer ${token}` }
+    });
+    const folders = await res.json();
+    
+    if (folders.length > 0) {
+        window.location.href = '/setup/unresolved';
+    } else {
+        window.location.href = '/login';
+    }
+}
+```
+
+**Post-NFO scan:**
+- Sets `nfo_scan_complete` flag
+- Redirects to `/login`
+
+### 3. Unresolved Folders Page (`/setup/unresolved`)
+
+**File:** `src/server/web/templates/unresolved.html`
+
+Allows manual resolution of folders that couldn't be auto-matched:
+- Shows list of unresolved folders
+- Provides search suggestions
+- Input field for entering provider key
+- Resolve/delete actions
+- **Done button** to complete the phase without resolving all folders
+
+**Allowed in states:** `UNRESOLVED_PENDING`
+
+**Done button behavior:**
+- Sets `unresolved_completed` flag
+- Redirects to `/loading` for final NFO scan
+
+**After completion:**
+- Any access redirects to `/loading`
+
+### 4. Login Page (`/login`)
+
+**File:** `src/server/web/templates/login.html`
+
+Authentication page. After successful login → redirect to `/` (main app).
+
+**Allowed in states:** `COMPLETE`
+

+### Testing FolderNamingService
+
+FolderNamingService fixes missing years in anime folder names after NFO refresh. Test file: `tests/unit/test_folder_naming_service.py`.
+
+Key methods tested:
+- `_build_target_folder()` — constructs safe "Title (YYYY)" names, strips existing year suffix first (prevents double-year like "Naruto (1999) (1999)")
+- `_folder_has_year()` — detects existing `(YYYY)` pattern
+- `_extract_year_from_folder_name()` — parses `(YYYY)` suffix
+- `_extract_title_from_folder_name()` — strips year suffix
+
+```python
+# Safe: repeated calls never accumulate years
+r1 = FolderNamingService._build_target_folder("Naruto", 1999)
+r2 = FolderNamingService._build_target_folder(r1, 1999)
+assert r1 == r2 == "Naruto (1999)"
+
+# Safe: existing year is replaced, not appended
+result = FolderNamingService._build_target_folder("Naruto (2020)", 1999)
+assert result == "Naruto (1999)"
+assert "2020" not in result
+```
+
+The service is also tested end-to-end with mocked filesystem and database:
+- Renames folder and updates DB when year is missing from folder name
+- Skips rename when folder already has a year
+- Skips rename when DB has no year
+- Skips when target folder already exists on disk
+- Safety guard detects and skips if target folder year mismatches DB year

+### Mocking aiohttp Sessions
+
+When testing code that uses `aiohttp.ClientSession`:
+
+```python
+from unittest.mock import AsyncMock, MagicMock, patch
+from aiohttp import ClientSession
+
+# Mock aiohttp session for testing
+class MockAiohttpSession:
+    def __init__(self):
+        self.closed = False
+    
+    async def close(self):
+        self.closed = True
+    
+    def get(self, url, **kwargs):
+        mock_response = AsyncMock()
+        mock_response.status = 200
+        mock_response.json = AsyncMock(return_value={"data": "test"})
+        mock_response.__aenter__ = AsyncMock(return_value=mock_response)
+        mock_response.__aexit__ = AsyncMock(return_value=None)

+async def mock_tmdb_session():
+    session = MockAiohttpSession()
+    yield session
+    # Cleanup verification
+    assert session.closed, "Session was not closed"
+```
+
+**Key points:**
+- Always verify `session.closed` is `True` after context manager exits
+- Mock `__aenter__` and `__aexit__` for response context managers

-# Migration Guide: File-Based to Database Storage
-
-## Overview
-
-This guide covers the transition from file-based series metadata storage to the new database-backed system introduced in v2.0.
-
-## What Changed
-
-**Before v2.0**: Series metadata stored in `key` and `data` files alongside anime folders.
-
-**After v2.0**: All metadata stored in SQLite database (`aniworld.db`). Files are deprecated but still supported for backward compatibility during migration.
-
-## Automated Migration
-
-The application automatically migrates on first startup:
-
-1. Scans anime directory for `key` and `data` files
-2. Parses legacy files into `AnimeSeries` and `Episode` records
-3. Loads series into in-memory cache
-4. Logs migration results
-
-**No manual action required.**
-
-## Manual Verification
-
-After first startup with the new version:
-
-1. **Check logs** for: `"Migrated X series from files to DB"`
-2. **Verify series count**: UI shows same number of series as before
-3. **Confirm episodes**: Episode counts match expected totals
-
-```bash
-# Check migration log
-grep "Migrated" logs/app.log
-
-# Verify series via API
-curl http://localhost:8000/api/anime | jq '.total'
-```
-
-## After Migration
-
-### Safe to Delete
-
-Once verified, these files can be removed:
-
-```
-<anime_folder>/
-├── Attack on Titan (2013)/
-│   ├── key     # ❌ Can delete
-│   ├── data    # ❌ Can delete
-│   └── Season 1/
-│       └── ...
-```
-
-**Deleting these files does not affect the database.** The metadata now lives in `aniworld.db`.
-
-### Backup (Recommended)
-
-Before deleting, backup the files:
-
-```bash
-# Create backup directory
-mkdir -p backup/legacy_series_files
-
-# Copy all key and data files
-find /path/to/anime -name "key" -o -name "data" | while read f; do
-    cp "$f" "backup/legacy_series_files/"
-done
-```
-
-## Reverting (Not Recommended)
-
-If you must revert to file-based storage:
-
-1. **Restore from database backup** (if available)
-2. **Export manually** (no export script exists)
-
-**Warning**: File-based storage is deprecated and will be removed in v3.0.0.
-
-## Troubleshooting
-
-### Series Not Appearing After Migration
-
-1. Check logs for migration errors: `grep -i error logs/app.log`
-2. Verify `key` and `data` files exist and are readable
-3. Manually trigger rescan: `POST /api/scheduler/trigger-rescan`
-
-### Duplicate Series
-
-1. Check for duplicate `key` files (same series in multiple folders)
-2. Verify series key uniqueness in database:
-
-```bash
-sqlite3 aniworld.db "SELECT key, COUNT(*) FROM anime_series GROUP BY key HAVING COUNT(*) > 1;"
-```
-
-### Missing Episodes
-
-1. Trigger targeted scan for affected series
-2. Check episode sync logs
-3. Verify file permissions on anime directory
-
-## Deprecation Timeline
-
-| Version | Status |
-|---------|--------|
-| v2.0.x  | Legacy files supported, migration automated |
-| v2.1.x  | Legacy files still supported, warnings in logs |
-| v3.0.0  | **Legacy files removed** - database only |
-
-Upgrade to v3.0.0 before legacy file support ends.

-
-### Mocking the Download Queue
-
-Use `MockQueueRepository` for testing download queue functionality:
-
-```python
-from src.server.models.download import DownloadItem, EpisodeIdentifier
-
-class MockQueueRepository:
-    def __init__(self):
-        self._items: Dict[str, DownloadItem] = {}
-
-    async def save_item(self, item: DownloadItem) -> DownloadItem:
-        self._items[item.id] = item
-        return item
-
-    async def get_item(self, item_id: str) -> Optional[DownloadItem]:
-        return self._items.get(item_id)
-
-    async def get_all_items(self) -> List[DownloadItem]:
-        return list(self._items.values())
-
-    async def set_error(self, item_id: str, error: str) -> bool:
-        if item_id in self._items:
-            self._items[item_id].error = error
-            return True
-        return False
-
-    async def delete_item(self, item_id: str) -> bool:
-        if item_id in self._items:
-            del self._items[item_id]
-            return True
-        return False
-
-    async def clear_all(self) -> int:
-        count = len(self._items)
-        self._items.clear()
-        return count
-```
-
-**Key points:**
-- The mock uses in-memory storage, no database required
-- All async methods are implemented (even if just pass-through)
-- `save_item` uses `item.id` as key (must be set before calling)
-- Suitable for unit tests only (no persistence)
-
-### Mocking aiohttp Sessions
-
-When testing code that uses `aiohttp.ClientSession`:
-
-```python
-from unittest.mock import AsyncMock, MagicMock, patch
-from aiohttp import ClientSession
-
-# Mock aiohttp session for testing
-class MockAiohttpSession:
-    def __init__(self):
-        self.closed = False
-    
-    async def close(self):
-        self.closed = True
-    
-    def get(self, url, **kwargs):
-        mock_response = AsyncMock()
-        mock_response.status = 200
-        mock_response.json = AsyncMock(return_value={"data": "test"})
-        mock_response.__aenter__ = AsyncMock(return_value=mock_response)
-        mock_response.__aexit__ = AsyncMock(return_value=None)
-        return mock_response
-
-# Use in fixture
-@pytest.fixture
-async def mock_tmdb_session():
-    session = MockAiohttpSession()
-    yield session
-    # Cleanup verification
-    assert session.closed, "Session was not closed"
-```
-
-**Key points:**
-- Always verify `session.closed` is `True` after context manager exits
-- Mock `__aenter__` and `__aexit__` for response context managers
-- Set `closed = False` on mock session for unclosed warning tests

-# Tasks
-
-## 1. Scheduled Folder Scan
-
-### Task 1.1: Add folder scan scheduler configuration
-
-**Where is that found**
-- `src/server/models/config.py` (`SchedulerConfig`)
-- `data/config.json` (example/default config)
-- `src/server/web/templates/setup.html` (setup UI)
-- `src/server/api/auth.py` (config save endpoint, if it validates scheduler fields)
-
-**Goal. How it should be**
-Add a new boolean field `folder_scan_enabled` (default `false`) to `SchedulerConfig`. When `true`, the scheduler will execute the folder maintenance routine during its scheduled run. Add the field to the setup page as a checkbox. Ensure existing configs without this field load successfully (Pydantic default handles this).
-
-**Possible traps and issues**
-- Backward compatibility: old `data/config.json` files must load without errors. Pydantic defaults solve this, but verify by loading an old config.
-- The setup page JavaScript must include the new field in the payload sent to `/api/config`.
-- Do not confuse this with `auto_download_after_rescan` — this is a separate toggle.
-
-**Docs changes needed**
-- `docs/CONFIGURATION.md`: Document the new `scheduler.folder_scan_enabled` option.
-- `docs/ARCHITECTURE.md`: Mention folder scan in the scheduler section.
-
-**Why this is needed**
-Users need an opt-in toggle to enable automatic daily folder maintenance (NFO repair, folder renaming, poster checks) without forcing it on everyone.
-
----
-
-### Task 1.2: Create FolderScanService skeleton
-
-**Where is that found**
-- New file: `src/server/services/folder_scan_service.py`
-- `src/server/services/scheduler_service.py` (to call it)
-
-**Goal. How it should be**
-Create a new `FolderScanService` class with a single async entry point `async def run_folder_scan(self) -> None`. The method should:
-1. Log start/completion with structlog.
-2. Check prerequisites (`settings.anime_directory` exists, `settings.tmdb_api_key` is set).
-3. Skip gracefully with a warning log if prerequisites are missing.
-4. Use a module-level semaphore (similar to `_NFO_REPAIR_SEMAPHORE`) to limit concurrent TMDB operations to 3.
-
-Keep the implementation empty for the sub-tasks (1.3–1.5) to fill in. Just add the skeleton and the semaphore.
-
-**Possible traps and issues**
-- Circular imports: `folder_scan_service.py` will import from `initialization_service`, `config.settings`, etc. Keep imports inside methods or at the bottom if circular issues arise.
-- The service should follow the singleton pattern like `SchedulerService` and `DownloadService` if it holds state, or be stateless. For simplicity, make it a plain class instantiated per call or a module-level function set.
-- Exception handling: any unhandled exception in the scheduled task should be caught and logged so it doesn't crash the scheduler.
-
-**Docs changes needed**
-- `docs/ARCHITECTURE.md`: Add `folder_scan_service.py` to the services list.
-
-**Why this is needed**
-Encapsulates the new daily maintenance logic in its own module, keeping `scheduler_service.py` clean and allowing the folder scan to be tested independently.
-
----
-
-### Task 1.3: Integrate NFO repair into folder scan
-
-**Where is that found**
-- `src/server/services/folder_scan_service.py`
-- `src/server/services/initialization_service.py` (`perform_nfo_repair_scan`)
-
-**Goal. How it should be**
-Inside `FolderScanService.run_folder_scan()`, call `perform_nfo_repair_scan(background_loader=None)` as the first step. Reuse the existing function exactly — do not copy its logic. Log a message before and after the call.
-
-**Possible traps and issues**
-- `perform_nfo_repair_scan` spawns `asyncio.create_task` for each repair. When called from the scheduler, these background tasks will still run after `run_folder_scan` returns. This is fine, but log that repairs are queued.
-- The function already handles missing `tmdb_api_key` and `anime_directory`, so the caller doesn't need to double-check, but the skeleton from Task 1.2 already checks prerequisites.
-- `perform_nfo_repair_scan` imports `nfo_needs_repair` and `NfoRepairService` inside the function, so no heavy import-time dependencies.
-
-**Docs changes needed**
-- `docs/NFO_GUIDE.md`: Update the "Automatic NFO Repair" section to state that repair now runs as part of the scheduled folder scan instead of every startup.
-
-**Why this is needed**
-Reuses the existing, tested NFO repair logic. Moves NFO repair from startup blocking to scheduled background maintenance.
-
----
-
-### Task 1.4: Validate and rename series folders
-
-**Where is that found**
-- `src/server/services/folder_scan_service.py`
-- `src/core/services/nfo_repair_service.py` (for `parse_nfo_tags` or similar NFO parsing)
-- `src/server/database/models.py` / `src/server/database/system_settings_service.py` (if folder paths are stored in DB)
-
-**Goal. How it should be**
-After NFO repair, iterate over every subfolder in `settings.anime_directory` that contains a `tvshow.nfo`. For each folder:
-1. Parse the NFO to extract `<title>` and `<year>` text values.
-2. Compute the expected folder name: `f"{title} ({year})"`.
-3. Sanitize the expected name for filesystem safety (remove/replace illegal characters like `/`, `\`, `:`, etc.).
-4. Compare with the current folder name (`series_dir.name`).
-5. If different, rename the folder using `series_dir.rename(expected_path)`.
-6. If the series path is stored in the database (check `anime_service` or DB models), update the database record to point to the new path.
-
-Skip folders where title or year is missing/empty. Log every rename action.
-
-**Possible traps and issues**
-- **Database path consistency**: If `Series` or `Episode` models store absolute or relative paths, renaming the folder on disk without updating the DB will break downloads, NFO updates, and the web UI. Must verify whether paths are stored in the DB and update them.
-- **Active downloads**: A series currently being downloaded should not be renamed. Check the download queue or lock status before renaming. If no lock mechanism exists, this is a major trap — document it.
-- **Filesystem permissions**: The app may not have write permission to the anime directory. Catch `PermissionError` and `OSError` and log gracefully.
-- **Special characters**: Titles like `"A / B"` or `"Show: Subtitle"` contain characters illegal in folder names. Define a sanitization function (e.g., replace `/` with `-`, remove trailing dots on Windows, etc.).
-- **Duplicate names**: Two different series could sanitize to the same name. Check if target path already exists before renaming.
-- **Path length limits**: Very long titles might exceed OS path limits.
-
-**Docs changes needed**
-- `docs/NFO_GUIDE.md`: Add a section "Folder Naming Convention" explaining the `<title> (<year>)` format.
-- `docs/CONFIGURATION.md`: Mention that enabling folder scan will rename folders.
-
-**Why this is needed**
-Enforces a consistent, predictable folder naming scheme across the library, making it easier for media center apps (Kodi, Jellyfin, Plex) to match metadata.
-
----
-
-### Task 1.5: Check and download missing poster.jpg
-
-**Where is that found**
-- `src/server/services/folder_scan_service.py`
-- `src/core/utils/image_downloader.py` (`ImageDownloader`)
-- `src/core/services/nfo_service.py` or `src/core/services/nfo_repair_service.py` (to get poster URL from NFO or TMDB)
-
-**Goal. How it should be**
-After folder renaming, iterate over series folders again (or combine with Task 1.4 loop). For each folder:
-1. Check if `poster.jpg` exists and has a size ≥ `ImageDownloader.min_file_size` (1 KB by default).
-2. If missing or too small:
-   a. Parse `tvshow.nfo` for `<thumb aspect="poster">` or `<thumb>` URL.
-   b. If no URL in NFO, skip (do not query TMDB again to keep tasks small; the NFO should already have it after repair).
-   c. Use `ImageDownloader` (with context manager) to download the image to `series_dir / "poster.jpg"`.
-   d. Validate the downloaded image with `ImageDownloader._validate_image` (or similar existing validation).
-3. Use the existing `_NFO_REPAIR_SEMAPHORE` or a new `POSTER_DOWNLOAD_SEMAPHORE` to limit concurrent downloads to 3.
-
-**Possible traps and issues**
-- **TMDB rate limiting**: Even downloading images hits TMDB CDN. The semaphore limits concurrency.
-- **Invalid images**: A download might produce a 0-byte or corrupted file. `ImageDownloader` already validates with PIL; reuse that.
-- **NFO without thumb URL**: If the NFO was created before thumb tags were added, there may be no URL. In that case, skip and log. A future task could query TMDB directly.
-- **Write permissions**: Same as Task 1.4.
-- **Async session sharing**: `ImageDownloader` manages its own `aiohttp` session. Use `async with ImageDownloader() as downloader:` to ensure cleanup.
-
-**Docs changes needed**
-- `docs/NFO_GUIDE.md`: Add "Poster Check" subsection under folder scan.
-- `docs/CONFIGURATION.md`: Mention that `nfo.download_poster` setting also affects scheduled poster checks.
-
-**Why this is needed**
-Ensures every series has artwork, which is required by most media center front-ends for a polished library view.

-## 2. Remove startup NFO repair
-
-### Task 2.1: Remove perform_nfo_repair_scan from startup lifespan
-
-**Where is that found**
-- `src/server/fastapi_app.py` (lifespan startup block, lines ~245 and ~319)
-- `src/server/services/initialization_service.py` (keep the function, just remove the call site)
-- `tests/integration/test_nfo_repair_startup.py`
-- `tests/unit/test_initialization_service.py` (tests that call `perform_nfo_repair_scan` directly can stay, but integration tests verifying startup wiring must change)
-
-**Goal. How it should be**
-1. In `src/server/fastapi_app.py`, remove the import of `perform_nfo_repair_scan` from the `initialization_service` import block.
-2. Remove the line `await perform_nfo_repair_scan(background_loader)` from the lifespan startup sequence.
-3. Update `tests/integration/test_nfo_repair_startup.py`:
-   - Remove or modify `test_perform_nfo_repair_scan_imported_in_lifespan` and `test_perform_nfo_repair_scan_called_after_media_scan` since the startup wiring is gone.
-   - Replace with a test that verifies `perform_nfo_repair_scan` is NOT called during startup (or simply delete the file if it has no other purpose).
-4. `tests/unit/test_initialization_service.py` tests for `perform_nfo_repair_scan` can remain because they test the function itself, not the startup wiring.
-
-**Possible traps and issues**
-- **Test failures**: `test_nfo_repair_startup.py` will fail immediately after the code change. It must be updated in the same PR.
-- **Documentation drift**: `docs/NFO_GUIDE.md`, `docs/CHANGELOG.md`, and `docs/ARCHITECTURE.md` all describe the startup NFO repair behavior. If docs are not updated, users will expect repair on every start.
-- **Background loader parameter**: The `background_loader` variable was created partly for `perform_nfo_repair_scan`. After removal, check if `background_loader` is still needed for other startup steps (yes — `perform_media_scan_if_needed` uses it). Do not remove `background_loader` entirely.
-- **Import cleanup**: Ensure no unused imports remain in `fastapi_app.py` after removal.
-
-**Docs changes needed**
-- `docs/NFO_GUIDE.md`: Update section 11 "Automatic NFO Repair" to remove startup references and state it runs via scheduler.
-- `docs/CHANGELOG.md`: Add an entry under "Changed" or "Removed" noting that startup NFO repair is replaced by scheduled folder scan.
-- `docs/ARCHITECTURE.md`: Update the startup sequence description.
-
-**Why this is needed**
-Running `perform_nfo_repair_scan` on every startup slows down server restarts, especially for large libraries. Moving it to a scheduled task keeps startup fast while still ensuring regular maintenance.
