# Admin Guide — tv.s8n.ru

The single page that tells you what to do and where to read more.
Anything not on this page lives in `docs/` — links inline.

## Where things live

| Thing | Where |
|---|---|
| Compose file | `docker-compose.yml` (this repo) → deployed at `nullstone:/opt/docker/jellyfin/` |
| Config + cache | `nullstone:/home/docker/jellyfin/{config,cache}/` |
| Media root | `nullstone:/home/user/media/{movies,tv,anime,musicvideos}/` |
| Traefik route | `/opt/docker/traefik/config/jellyfin-test.yml` (file-provider — see [docs/04 § routing-quirk](docs/04-theming-and-users.md)) |
| Pi-hole DNS pin | `/opt/docker/pihole/etc-pihole/custom.list` → `192.168.0.100 tv.s8n.ru` |
| User wrapper | `bin/add-jellyfin-user.sh` (always use this) |

## Daily ops

### Add a new user
**Always** use the wrapper. UI signup skips the canonical home layout + subtitle/audio prefs.

```bash
JELLYFIN_TOKEN=<admin-token> ./bin/add-jellyfin-user.sh <username> <password>
```

What it does → [docs/04 § friend playbook](docs/04-theming-and-users.md).
Why it exists (Jellyfin has no native global default) → see same doc.

### Add new media

1. Drop source into `/home/admin/Downloads/<show or movie>/` on onyx.
2. Run cleanup: strip junk per [docs/07](docs/07-pre-import-cleanup.md). Use `bin/cleanup-import.sh` once written; for now follow the rules in that doc by hand.
3. Normalize filenames per [docs/08](docs/08-filename-normalization.md). Use `bin/normalize.py` once written.
4. Stage to `/home/admin/staging-jelly-<title>/<canonical-name>/`.
5. `scp -r` to `nullstone:/home/user/media/<lib>/`.
6. Trigger refresh: `curl -X POST -H "Authorization: MediaBrowser Token=$TOKEN" https://tv.s8n.ru/Library/Refresh`.
7. Verify: hit the URL, check artwork + titles + episode counts.
8. **Only after confirmed working**: delete the source download + the staging dir.

Naming + folder rules: [docs/05](docs/05-file-structure-rules.md).

### Library not scraping right

Symptoms → fix:

| Symptom | Cause | Fix doc |
|---|---|---|
| No posters / backdrops | `EnableInternetProviders=false` or wrong fetcher name | [docs/01](docs/01-artwork-and-images.md) |
| Episode titles blank or filenames | Series has empty `ProviderIds` (never matched) | [docs/02 § Identify flow](docs/02-metadata-and-titles.md) |
| Wrong show matched | Auto-match picked sequel/reboot | [docs/02 § locking the right show](docs/02-metadata-and-titles.md) |
| Polish/wrong language | Library `PreferredMetadataLanguage` mismatch | [docs/02 § language cascade](docs/02-metadata-and-titles.md) |

### Subtitles not auto-downloading

→ [docs/03 § OpenSubtitles plugin setup](docs/03-subtitles.md).
Owner needs an opensubtitles.com account (NOT .org). Free tier = 20/day.

### Theme broke after Jellyfin upgrade

ElegantFin imports from `cdn.jsdelivr.net/gh/lscambo13/ElegantFin@main/...` — auto-fixes itself most of the time. If the upstream theme breaks on a JF version bump, pin to a known-good tag. Procedure: [docs/04 § maintenance](docs/04-theming-and-users.md).

## Operational rules (these are non-negotiable)

1. **Wrapper-only user creation.** Don't create users in the Dashboard UI. Always run `bin/add-jellyfin-user.sh` so the layout + prefs are consistent. Doc 04.
2. **Stage before import.** Never drop raw downloads into `/home/user/media/`. Always clean + normalize first. Docs 05/07/08.
3. **Verify before delete.** Don't delete source downloads or old library entries until the new content is confirmed playing in the Jellyfin UI.
4. **No bind-mount drift.** If you change `docker-compose.yml`, commit + push to `git.s8n.ru/s8n/jellyfin-stack` in the same step. The repo is the source of truth for the deploy. Doc memory: `feedback_always_commit_to_my_git.md`.
5. **No public DNS.** `tv.s8n.ru` resolves only via Pi-hole locally. Do NOT add a Gandi A record. LAN-only is the threat model.

## Emergency rollback

| Operation | Rollback |
|---|---|
| Bad CustomCss change | `curl -X POST .../System/Configuration/branding` with prior backup |
| Compose change broke startup | `git checkout HEAD~ docker-compose.yml && docker compose up -d` |
| Library scan loop stuck | Settings → Dashboard → Scheduled Tasks → cancel "Scan Media Library" |
| New media import wrong | Don't panic. The source download is still in `/home/admin/Downloads/`. Delete the bad import dir on nullstone, redo cleanup/normalize step |
