chore: bump version

Use the database as the authoritative source for missing-episode lists so
that episodes marked is_downloaded=True are never shown as missing, even
when the in-memory state is stale.

Key changes:
- EpisodeService.get_by_series() gains only_missing flag
- AnimeService uses DB-backed episodeDict and preserves downloaded episodes
  during sync, skipping them when adding/removing missing episodes
- DownloadService broadcasts series_updated after marking an episode downloaded
  so the frontend reflects the change immediately
- Frontend filters out series with zero missing episodes client-side and
  fixes renderSeries to respect the active filter
- Unit tests updated to assert the broadcast is sent

+- `_last_auto_download_time` tracks when auto-download last ran
+- 5-minute cooldown prevents rapid re-triggers
+- Checked at start of `_auto_download_missing()`
+
+### Episode Lifecycle
+
+Episodes transition through states stored in the `episodes` table:
+
+| State | `is_downloaded` | `file_path` | Description |
+|-------|----------------|-------------|-------------|
+| Missing | `False` | `NULL` | Episode not yet downloaded |
+| Downloaded | `True` | Set | Episode exists on disk |
+
+**State Transitions:**
+1. **Missing → Downloaded**: When download completes, `_remove_episode_from_missing_list()` calls `EpisodeService.mark_downloaded()` to set `is_downloaded=True` and populate `file_path`. The episode record is NOT deleted.
+
+**Query Implications:**
+- `get_series_with_missing_episodes()`: Filters for `is_downloaded=False` to find series with undownloaded episodes
+- `get_series_with_no_episodes()`: Finds series with `is_downloaded=False` episodes but NO `is_downloaded=True` episodes (completely unwatched series)
+
+### Mocking the Download Queue
+
+When testing components that use the download queue:
+
+```python
+# Mock repository for unit tests
+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_all_items(self) -> List[DownloadItem]:
+        return list(self._items.values())
+
+# Use in fixture
+@pytest.fixture
+def mock_queue_repository():
+    return MockQueueRepository()
+
+@pytest.fixture
+def download_service(mock_anime_service, mock_queue_repository):
+    return DownloadService(
+        anime_service=mock_anime_service,
+        queue_repository=mock_queue_repository,
+        max_retries=3,
+    )
+```
+
 9. Troubleshooting Development Issues
+
+### Async Context Managers for aiohttp
+
+All `aiohttp.ClientSession` usages must be wrapped in `async with`:
+
+```python
+# Correct — session properly closed on exit
+async with TMDBClient(api_key="key") as client:
+    result = await client.search_tv_show("Show")
+
+# Wrong — session may leak if exception occurs
+client = TMDBClient(api_key="key")
+result = await client.search_tv_show("Show")
+await client.close()  # May not be called if exception raised earlier
+```
+
+**Why:**
+- `aiohttp.ClientSession` holds TCP connections that must be explicitly closed
+- If exception occurs before `close()`, session leaks
+- Context manager guarantees `__aexit__` runs even on exceptions
+
+**Services that use aiohttp:**
+- `TMDBClient` — has `__aenter__`/`__aexit__`, use `async with`
+- `ImageDownloader` — has `__aenter__`/`__aexit__`, use `async with`
+- `NFOService` — wraps both above, use `async with`
+
+**Verification:**
+- Missing context manager usage triggers `__del__` warning on garbage collection
+- Integration tests verify no "Unclosed client session" errors in logs
+
+### Scheduler Persistence and Recovery
+
+APScheduler stores jobs in `data/scheduler.db` (SQLite) so they survive process restarts:
+
+```python
+from apscheduler.jobstores.sqlalchemy import SQLAlchemyJobStore
+
+jobstores = {
+    "default": SQLAlchemyJobStore(url="sqlite:///./data/scheduler.db"),
+}
+scheduler = AsyncIOScheduler(jobstores=jobstores)
+```
+
+**Grace period:** `misfire_grace_time=3600` (1 hour). If server is down at scheduled time and restarts within 1 hour, missed job runs automatically via APScheduler coalesce behavior.
+
+**Startup recovery:** On `start()`, scheduler loads persisted jobs from DB. APScheduler handles missed jobs internally when `coalesce=True`.
+
+**Health endpoint:** `GET /health` returns `scheduler_next_run` and `scheduler_last_run` for external monitors (Uptime Kuma, Prometheus, etc.).
+
+**If server is down >1 hour:** No automatic recovery. Manual trigger via `POST /api/scheduler/trigger-rescan` or wait for next scheduled run.
+
+### Health Check Endpoints
+
+The application provides health check endpoints for monitoring and container orchestration:
+
+#### `GET /health`
+Basic health check returning service status and startup health check results.
+
+**Response fields:**
+- `status`: "healthy", "degraded", or "unhealthy" based on startup checks
+- `timestamp`: ISO timestamp of the check
+- `series_app_initialized`: Whether the series app is loaded
+- `anime_directory_configured`: Whether anime_directory is set
+- `scheduler_next_run` / `scheduler_last_run`: Scheduler times
+- `checks`: Detailed startup check results (ffmpeg, DNS, anime_directory)
+
+#### `GET /health/ready`
+Readiness check for container orchestrators (Kubernetes, Docker Swarm).
+
+**Response when ready:**
+```json
+{
+  "status": "ready",
+  "ready": true,
+  "timestamp": "2024-01-01T00:00:00",
+  "checks": {...}
+}
+```
+
+**Response when not ready (503):**
+```json
+{
+  "status": "not_ready",
+  "ready": false,
+  "timestamp": "2024-01-01T00:00:00",
+  "critical_failures": ["anime_directory: not configured"],
+  "checks": {...}
+}
+```
+
+#### `GET /health/detailed`
+Comprehensive health check including database, filesystem, and system metrics.
+
+#### Startup Health Checks
+
+On application startup, the following checks are performed:
+
+| Check | Failure Status | Impact |
+|-------|---------------|--------|
+| `ffmpeg` | warning | HLS downloads may fail |
+| `dns_aniworld` | warning | Provider requests may fail |
+| `dns_tmdb` | warning | TMDB API calls may fail |
+| `anime_directory` | error | Download service disabled |
+
+DNS checks are warnings because failures can be transient. anime_directory errors disable the download service to prevent failures.
+
+### Troubleshooting Development Issues
+
+#### Scheduler missed a run
+
+1. Server was down at scheduled time (03:00 UTC by default).
+2. Check `data/scheduler.db` exists — if not, jobs are not persisted.
+3. If server was down >1 hour, missed job is dropped (misfire window exceeded).
+4. Trigger manually: `POST /api/scheduler/trigger-rescan`
+5. Monitor next run: `GET /health` → `scheduler_next_run`
+6. If problem repeats, increase `misfire_grace_time` in `scheduler_service.py`.
+
+#### Scheduler not firing (no events at scheduled time)
+
+If the scheduler appears configured but never triggers:
+
+1. **Verify scheduler.db contains the job:**
+   ```bash
+   sqlite3 data/scheduler.db "SELECT id, next_run_time FROM apscheduler_jobs;"
+   ```
+   - `next_run_time` should be in the future
+   - If it's in the past, the server was down when the job should have fired
+
+2. **Check application logs for scheduler startup:**
+   ```
+   grep "Scheduler service started" fastapi_app.log
+   ```
+   - If missing, the scheduler failed to start — check for errors above this line
+   - If present, scheduler started successfully
+
+3. **Verify APScheduler events in logs:**
+   ```
+   grep "apscheduler.executors.default" fastapi_app.log
+   ```
+   - `Running job` = job triggered
+   - `executed successfully` = job completed
+   - No output = job never fired
+
+4. **Test manual trigger:**
+   ```bash
+   curl -X POST http://localhost:8000/api/scheduler/trigger-rescan -H "Authorization: Bearer <token>"
+   ```
+   - If manual trigger works but cron doesn't, the issue is APScheduler configuration
+
+5. **Check next_run_time via health endpoint:**
+   ```bash
+   curl http://localhost:8000/health | jq .scheduler_next_run
+   ```
+   - If `null`, the job is not scheduled
+   - If set, the scheduler knows when to run next
+
+6. **Check timezone handling:**
+   - APScheduler uses UTC internally
+   - The schedule_time config (e.g., "03:00") is interpreted as UTC
+   - If you expect local time, adjust the schedule_time accordingly
+
+#### Startup health check failures
+
+If `/health` returns `unhealthy` status:
+
+1. **anime_directory error**: Directory not configured or not writable
+   - Check `ANIME_DIRECTORY` environment variable
+   - Verify directory exists and permissions allow write access
+   - Download service will not initialize until resolved
+
+2. **ffmpeg warning**: ffmpeg not found in PATH
+   - HLS stream downloads will fail
+   - Install ffmpeg: `apt install ffmpeg` or `brew install ffmpeg`
+
+3. **DNS warnings**: Domain resolution failed
+   - Check network connectivity
+   - DNS failures are transient — warnings don't block startup
+   - Retry later to verify: `GET /health`
+
+### Provider Failure Handling
+
+Download providers (VOE, Doodstream, Vidmoly, Vidoza, SpeedFiles, Streamtape,
+Luluvdo) regularly break: URLs expire, sites change their player markup, geo
+blocks appear, and `yt-dlp` extractors lag behind upstream changes. The
+`AniworldLoader.download()` flow is designed to fail fast and rotate.
+
+**Rotation order**
+
+1. The episode page is scraped for the providers AniWorld actually advertises.
+2. Results are ordered by the preference in `DEFAULT_PROVIDERS`
+   (`provider_config.py`); providers not listed run last.
+3. For each candidate the loader:
+   1. Calls `_check_url_alive()` — HEAD probe with GET fallback. Any 4xx
+      response or connection error skips the provider immediately.
+   2. Resolves the redirect via `_resolve_direct_link()` to obtain a direct
+      stream URL plus headers. Provider-specific extractors (e.g. `VOE`) are
+      preferred; unknown providers fall back to the embed URL so `yt-dlp` can
+      attempt extraction.
+   3. Tries `_try_direct_stream()` — straight `requests.get(stream=True)` when
+      `Content-Type` is `video/*` or `application/octet-stream`. This avoids
+      `yt-dlp` entirely for direct MP4 links.
+   4. Falls back to `yt-dlp` with the ffmpeg downloader for HLS streams.
+4. On any failure, temp files are cleaned and the loop moves to the next
+   provider. When the chain is exhausted, the loader logs
+   `All download providers failed for S{season}E{episode} ...; tried=[...]`
+   to both the application log and `logs/download_errors.log`.
+
+**Do not hardcode provider URLs.** Provider domains shift constantly (e.g.
+Doodstream alternates between `dood.li`, `dood.so`, `dood.la`). Only the
+referer hints in `PROVIDER_HEADERS` are persisted — discovery still happens
+at runtime through AniWorld's redirect endpoint.
+
+### HLS Stream Handling
+
+HLS (HTTP Live Streaming) manifests (`.m3u8`) require yt-dlp to use the
+`ffmpeg` downloader with `--hls-use-mpegts`. Both providers configure this
+automatically:
+
+```python
+ydl_opts = {
+    "downloader": "ffmpeg",     # Use ffmpeg instead of native
+    "hls_use_mpegts": True,     # Write transport stream (.ts) segments
+}
+```
+
+**Why this matters**: Without ffmpeg, yt-dlp logs:
+`"Live HLS streams are not supported by the native downloader"`
+
+**Requirements**:
+- ffmpeg must be installed and in PATH (`which ffmpeg`)
+- Install: `apt install ffmpeg` (Debian/Ubuntu) or `brew install ffmpeg` (macOS)
+- Startup health check (see Health Check Endpoints) verifies ffmpeg presence
+
+**Trade-offs**:
+- HLS downloads are slower than direct MP4 (reassembly of .ts segments)
+- Requires more disk space during download
+- May need post-processing if .ts format is not desired
+
+**Detection**: VOE provider extracts HLS URLs via `HLS_PATTERN` regex. Other
+providers let yt-dlp auto-detect from URL/content-type.
+
+### Updating yt-dlp
+
+When extractors break (typical symptoms: every provider HEAD probe succeeds
+but `yt-dlp` raises `Unable to extract` or `HTTP Error 404`):
+
+1. Check the upstream tracker first: https://github.com/yt-dlp/yt-dlp/issues
+2. Upgrade in the conda environment:
+   ```bash
+   conda run -n AniWorld pip install --upgrade yt-dlp
+   ```
+3. Smoke-test against a known-good episode before pinning a new floor in
+   `requirements.txt` (`yt-dlp>=YYYY.MM.DD`).
+4. Re-run the provider test suite:
+   ```bash
+   conda run -n AniWorld python -m pytest tests/unit/test_aniworld_provider.py -v
+   ```
+5. If a specific extractor is removed upstream, drop the provider from
+   `DEFAULT_PROVIDERS` rather than patching `yt-dlp` in tree.
+
+### User Notification on Total Failure
+
+`SeriesApp.download_episode()` already emits a `download_status="failed"`
+WebSocket event when `loader.download()` returns `False`. Operators should
+forward this to `notification_service.notify_download_failed()` so users see
+a HIGH-priority alert. The loader keeps the failure detail in
+`logs/download_errors.log` for post-mortem.

+### 3.6 Fallback Behavior When TMDB is Unavailable
+
+When TMDB lookup fails (network issues, API errors, or no match found), the system creates a **minimal NFO** to ensure the series is still tracked. This behavior applies to:
+
+- Manual NFO creation via API
+- Batch NFO creation operations
+- Automatic NFO creation during downloads
+
+**What a minimal NFO contains:**
+
+```xml
+<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
+<tvshow>

+    <year>2024</year>
+    <plot>No metadata available for Series Name. TMDB lookup failed.</plot>
+</tvshow>
+```
+
+**Limitations of minimal NFOs:**
+- No poster, logo, or fanart images
+- No rating, genre, or studio information
+- No TMDB or other provider IDs
+- May not display correctly in some media servers
+
+**To upgrade a minimal NFO:**
+1. Use the Update endpoint (`PUT /api/nfo/{serie_id}/update`) when TMDB is available
+2. Or delete the NFO and recreate it with full metadata

+## 5. Folder Naming Convention
+
+### 5.1 Expected Format
+
+After the daily folder scan (when **Update on library scan** is enabled), Aniworld validates every series folder against its `tvshow.nfo` metadata. If the folder name does not match the expected convention, it is automatically renamed.
+
+**Format:**
+
+```
+{title} ({year})
+```
+
+**Examples:**
+
+| NFO `<title>` | NFO `<year>` | Expected Folder Name |
+|---------------|--------------|----------------------|
+| `Attack on Titan` | `2013` | `Attack on Titan (2013)` |
+| `One Piece` | `1999` | `One Piece (1999)` |
+| `Demon Slayer: Kimetsu no Yaiba` | `2019` | `Demon Slayer Kimetsu no Yaiba (2019)` |
+
+### 5.2 Sanitization Rules
+
+Illegal filesystem characters are removed or replaced to ensure cross-platform compatibility:
+
+- Removed: `< > : " / \ | ? *` and null bytes
+- Control characters stripped
+- Multiple spaces collapsed to one
+- Leading/trailing dots and whitespace trimmed
+- Maximum length: 200 characters (truncated at word boundary if possible)
+
+### 5.3 Skip Conditions
+
+A folder is **not** renamed when any of the following apply:
+
+- `tvshow.nfo` is missing `<title>` or `<year>` (or they are empty)
+- The series has an **active or pending download**
+- The target folder name already exists (duplicate)
+- The resulting path would exceed the OS path-length limit
+- The app lacks write permission to the anime directory
+
+All skipped and renamed actions are logged.

+
+## 6. Poster Check
+
+### 6.1 Overview
+
+During the daily folder scan, Aniworld checks every series folder for a valid `poster.jpg`. If the file is missing or smaller than 1 KB, the application attempts to re-download it from the URL stored in the series' `tvshow.nfo` file.
+
+### 6.2 How It Works
+
+1. **Scan** — After folder renaming, the scan iterates over all series folders that contain a `tvshow.nfo`.
+2. **Validate** — For each folder, it checks whether `poster.jpg` exists and is at least 1 KB.
+3. **Parse NFO** — If the poster is missing or too small, the scan reads `tvshow.nfo` and looks for a `<thumb aspect="poster">` (or any `<thumb>`) URL.
+4. **Download** — If a URL is found, the poster is downloaded using `ImageDownloader` with a concurrency limit of 3 simultaneous downloads.
+5. **Validate Download** — The downloaded image is validated with PIL to ensure it is not corrupted.
+
+### 6.3 Skip Conditions
+
+A folder is **not** processed for poster download when any of the following apply:
+
+- `tvshow.nfo` does not exist in the folder.
+- `poster.jpg` already exists and is ≥ 1 KB.
+- No `<thumb>` URL is found in the NFO (the NFO may have been created before thumb tags were added).
+- The `nfo.download_poster` setting is `false` (poster checks are still performed, but downloads are skipped if the setting is disabled; see [CONFIGURATION.md](CONFIGURATION.md)).
+
+### 6.4 Logging
+
+Every poster check action is logged:
+
+- **INFO** — When a poster is successfully downloaded.
+- **WARNING** — When a download fails or no URL is found.
+- **ERROR** — When an unexpected exception occurs during download.

 ## 11. Automatic NFO Repair
 
-Every time the server starts, Aniworld scans all existing `tvshow.nfo` files and
-automatically repairs any that are missing required tags.
+NFO repair now runs as part of the scheduled daily folder scan rather than on every
+startup.  When the scheduler triggers `FolderScanService.run_folder_scan()`, the first
+step is `perform_nfo_repair_scan(background_loader=None)`.  Each incomplete NFO is
+queued as a background `asyncio` task, so the scan returns quickly while repairs
+continue asynchronously.
 
 ### How It Works
 
 1. **Scan** — `perform_nfo_repair_scan()` in
-   `src/server/services/initialization_service.py` is called from the FastAPI
-   lifespan after `perform_media_scan_if_needed()`.
+   `src/server/services/initialization_service.py` is called from
+   `FolderScanService.run_folder_scan()` (`src/server/services/folder_scan_service.py`).
 2. **Detect** — `nfo_needs_repair(nfo_path)` from
    `src/core/services/nfo_repair_service.py` parses each `tvshow.nfo` with
    `lxml` and checks for the 13 required tags listed below.
 3. **Repair** — Series whose NFO is incomplete are queued for background reload
-   via `BackgroundLoaderService.add_series_loading_task()`. The background
-   loader re-fetches metadata from TMDB and rewrites the NFO with all tags
-   populated.
+   via `asyncio.create_task`. Each task creates its own isolated
+   :class:`NFOService` / :class:`TMDBClient` so concurrent tasks never share an
+   ``aiohttp`` session — this prevents "Connector is closed" errors when many repairs
+   run in parallel.  A semaphore caps TMDB concurrency at 3 to stay within rate limits.

+### 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:

+        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):

+    
+    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
+- Set `closed = False` on mock session for unclosed warning tests

-# Tasks — NFO Plot Missing Bug
+# Tasks
 
-These tasks fix the root causes of `<plot>` being empty in `tvshow.nfo` after adding a series via the web UI.
-The bug does **not** appear after a server restart because the repair scan uses a different, correctly isolated code path.
+## 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 — Replace shared NFOService in BackgroundLoaderService with per-task instances
+### Task 1.2: Create FolderScanService skeleton
 
-- [x] Completed
+**Where is that found**
+- New file: `src/server/services/folder_scan_service.py`
+- `src/server/services/scheduler_service.py` (to call it)
 
-### Where
-`src/server/services/background_loader_service.py` — method `_load_nfo_and_images` (~line 555)
+**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.
 
-```python
-nfo_path = await self.series_app.nfo_service.create_tvshow_nfo(
-    serie_name=task.name,
-    serie_folder=task.folder,
-    year=task.year,
-    ...
-)
-```
+Keep the implementation empty for the sub-tasks (1.3–1.5) to fill in. Just add the skeleton and the semaphore.
 
-### Goal
-Create a fresh, isolated `NFOService` (with its own `TMDBClient` and `aiohttp` session) for every background loading task, exactly the same way `_repair_one_series` in `initialization_service.py` already does it.
-Each task must own its client so that closing the session at the end of one task never kills an in-flight request inside another task.
+**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.
 
-### How it should look
-```python
-from src.core.services.nfo_factory import NFOServiceFactory
+**Docs changes needed**
+- `docs/ARCHITECTURE.md`: Add `folder_scan_service.py` to the services list.
 
-factory = NFOServiceFactory()
-nfo_service = factory.create()
-nfo_path = await nfo_service.create_tvshow_nfo(
-    serie_name=task.name,
-    serie_folder=task.folder,
-    year=task.year,
-    ...
-)
-```
-
-### Possible traps and issues
-- `NFOServiceFactory.create()` raises `ValueError` if no TMDB API key is available.  Wrap in try/except and fall back gracefully (same behaviour as now when `nfo_service` is `None`).
-- The factory reads the API key from `settings` first, then from `config.json`. Do not pass the key explicitly so the fallback chain stays intact.
-- Each new `NFOService` opens its own `aiohttp` connector. Make sure to call `await nfo_service.close()` in a `finally` block to avoid connector leaks.
-
-### Docs changes needed
-None — this is an internal implementation detail.
-
-### Why this is needed
-Up to 5 background workers share one `NFOService`/`TMDBClient` instance. The `async with self.tmdb_client:` context manager inside `create_tvshow_nfo` calls `close()` on `__aexit__`, setting `session = None`. When Worker B exits its context while Worker A is still inside `_enrich_details_with_fallback` trying the `en-US` fallback request, that request throws "Connector is closed". The exception is silently swallowed, both `en-US` and `ja-JP` fallbacks fail, `details["overview"]` stays empty, and `plot` is written as an empty element.
+**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 2 — Guard NFOService init in SeriesApp on factory fallback, not just env var
+### Task 1.3: Integrate NFO repair into folder scan
 
-- [x] Completed
+**Where is that found**
+- `src/server/services/folder_scan_service.py`
+- `src/server/services/initialization_service.py` (`perform_nfo_repair_scan`)
 
-### Where
-`src/core/SeriesApp.py` — `__init__` method (~line 175)
+**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.
 
-```python
-self.nfo_service: Optional[NFOService] = None
-if settings.tmdb_api_key:          # ← checks env var ONLY
-    factory = get_nfo_factory()
-    self.nfo_service = factory.create()
-```
+**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.
 
-### Goal
-The guard condition should be equivalent to what `NFOServiceFactory.create()` itself checks: whether the key is available from *any* source (env var or `config.json`). Replace the guard with a try/create pattern so that `nfo_service` is initialised whenever the factory would succeed.
+**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.
 
-### How it should look
-```python
-self.nfo_service: Optional[NFOService] = None
-try:
-    from src.core.services.nfo_factory import get_nfo_factory
-    factory = get_nfo_factory()
-    self.nfo_service = factory.create()
-    logger.info("NFO service initialized successfully")
-except ValueError:
-    logger.info("NFO service not available — TMDB API key not configured")
-except Exception as e:
-    logger.warning("Failed to initialize NFO service: %s", e)
-```
-
-### Possible traps and issues
-- This changes the condition from "env var set" to "factory can produce a service". The factory already has a safe fallback and raises `ValueError` when no key exists — so the `except ValueError` path is the normal "not configured" case, not an error.
-- `SeriesApp` is used in tests with `settings.tmdb_api_key = None`. Those tests must not be affected; the `except ValueError` branch keeps behaviour identical.
-- `series_app.nfo_service` is still `None` when not configured — downstream code that checks `if self.series_app.nfo_service:` remains correct.
-
-### Docs changes needed
-`docs/CONFIGURATION.md` — note that `TMDB_API_KEY` env var is not required if `nfo.tmdb_api_key` is set in `config.json`.
-
-### Why this is needed
-If the TMDB API key is configured only via `config.json` (not the `TMDB_API_KEY` env var), `settings.tmdb_api_key` is `None` and the guard prevents `nfo_service` from ever being created. The background loader then skips NFO creation completely (`nfo_service` is `None`). The repair scan at startup uses `NFOServiceFactory` directly (reads config.json) so it does create the NFO — which is exactly why restart works but add does not.
+**Why this is needed**
+Reuses the existing, tested NFO repair logic. Moves NFO repair from startup blocking to scheduled background maintenance.
 
 ---
 
-## Task 3 — Remove non-reentrant `async with self.tmdb_client:` from NFOService public methods
+### Task 1.4: Validate and rename series folders
 
-- [x] Completed
+**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)
 
-### Where
-`src/core/services/nfo_service.py` — `create_tvshow_nfo` (~line 151) and `update_tvshow_nfo` (~line 265)
+**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.
 
-```python
-async with self.tmdb_client:
-    details = await self.tmdb_client.get_tv_show_details(...)
-    ...
-```
+Skip folders where title or year is missing/empty. Log every rename action.
 
-### Goal
-The `TMDBClient.__aenter__` / `__aexit__` open and **close** the session, making any concurrent call to the same client instance fail. Because Task 1 creates a fresh instance per call, this context manager becomes redundant. Change both methods to use `_ensure_session()` at the start and `close()` in a `finally` block, or simply call `await self.tmdb_client._ensure_session()` once and close after all requests. This makes the lifetime explicit and prevents double-close if the caller already manages it.
+**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.
 
-### How it should look
-```python
-async def create_tvshow_nfo(self, ...) -> Path:
-    try:
-        await self.tmdb_client._ensure_session()
-        search_results = await self.tmdb_client.search_tv_show(search_name)
-        ...
-    finally:
-        await self.tmdb_client.close()
-```
+**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.
 
-### Possible traps and issues
-- `TMDBClient.close()` is idempotent (checks `session.closed` before closing), so calling it in `finally` is safe even if the try block never opened a session.
-- After Task 1 every `NFOService` is short-lived (one call), so `finally: close()` effectively replaces the context manager with no behaviour change.
-- Do not remove the `__aenter__`/`__aexit__` from `TMDBClient` itself — other callers (e.g. tests, CLI) may still use it as a context manager.
-- `update_tvshow_nfo` has the same pattern; fix both methods.
-
-### Docs changes needed
-None — internal implementation detail.
-
-### Why this is needed
-Even after Task 1 fixes the shared-instance problem, the `async with self.tmdb_client:` pattern is fragile by design: `__aexit__` calls `close()`, which would break any hypothetical future reuse. Removing the implicit close makes the session lifetime explicit and eliminates the root mechanism that caused the original bug.
+**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 4 — Add `en-US` search fallback so `search_overview` is never empty
+### Task 1.5: Check and download missing poster.jpg
 
-### Where
-`src/core/services/nfo_service.py` — `create_tvshow_nfo` (~line 178) and `_enrich_details_with_fallback` (~line 395)
+**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)
 
-```python
-search_overview = tv_show.get("overview") or None  # always None for anime — de-DE search returns ""
-```
+**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.
 
-### Goal
-When the German `search_tv_show` result has an empty `overview`, perform a second search in `en-US` to obtain a non-empty overview as the last-resort fallback text. Store this as `search_overview` so `_enrich_details_with_fallback` can use it even if all language-specific detail requests fail.
+**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.
 
-### How it should look
-```python
-search_overview = tv_show.get("overview") or None
-if not search_overview:
-    try:
-        en_results = await self.tmdb_client.search_tv_show(search_name, language="en-US")
-        en_match = self._find_best_match(en_results.get("results", []), search_name, year)
-        search_overview = en_match.get("overview") or None
-    except Exception:
-        pass  # best-effort only
-```
+**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.
 
-### Possible traps and issues
-- This adds one extra TMDB request per series when the German overview is empty. It is best-effort and must be wrapped in a broad `except` so it never blocks NFO creation.
-- The TMDB search endpoint rate-limit is generous; one extra request per add is negligible.
-- `_find_best_match` can raise `TMDBAPIError` if the result list is empty — catch both `TMDBAPIError` and `Exception`.
-- `update_tvshow_nfo` calls `_enrich_details_with_fallback` without `search_overview`. This is acceptable because the detail request with `en-US` fallback covers it; the search overview is only a last resort for the create path.
+**Why this is needed**
+Ensures every series has artwork, which is required by most media center front-ends for a polished library view.
 
-### Docs changes needed
-None — transparent improvement.
+---
 
-### Why this is needed
-Most anime have no German translation on TMDB. The `de-DE` search result returns `overview: ""`. The current code stores this as `search_overview = None` so the last-resort fallback in `_enrich_details_with_fallback` never fires. Combined with session contention (Task 1), the detail-level `en-US` fallback also fails, leaving `plot` empty. This task ensures that at least the search-level `en-US` overview is available as a safety net.
+## 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.
