tommy 72d540fb85 4K quality-first arr stack: radarr-4k + sonarr-4k (Step 1 standup+wiring)
Separate instances (ports 7879/8990) on the shared /mnt/media/data hardlink tree.
Ansible inline-compose (idempotent). Wired: Prowlarr apps+sync, Overseerr native-4K
servers (existing radarr is4k mislabel corrected), separate Plex 4K libraries,
Traefik file-provider routers. Tdarr excludes the 4K roots. Recyclarr = deferred Step 2.

# 4K Quality-First arr stack — radarr-4k + sonarr-4k
SEPARATE instances from the untouched 1080p stack (for Overseerr native-4K routing +
isolation). Host: media-server (.183). Deployed by `deploy-arrs-4k.yml` (inline-compose,
idempotent, changed=0).
## Instances
| | port (host:cont) | URL | root folder |
|---|---|---|---|
| radarr-4k | 7879:7878 | radarr-4k.goattw.net | /data/media/movies-4k |
| sonarr-4k | 8990:8989 | sonarr-4k.goattw.net | /data/media/tv-4k |
- Image `lscr.io/linuxserver/{radarr,sonarr}:latest`, PUID/PGID 1000, net `traefik_public`.
- Mount `/mnt/media/data -> /data` — SAME single hardlink tree as the 1080p stack + download
clients (st_dev verified identical), so imports are instant hardlinks. NFS from
TrueNAS `Tank/Media`. Roots created 1000:3000 775 (match 1080p).
## Wiring (Step 1, done)
- **Prowlarr**: `Radarr (4K)`/`Sonarr (4K)` applications (fullSync), indexers synced.
- **Overseerr**: radarr-4k/sonarr-4k as `is4k=true` servers (native 4K routing). The existing
1080p radarr was mislabeled `is4k=true` and was flipped to `is4k=false` (non-4k default).
- **Plex**: SEPARATE libraries `Movies - 4K` (/data/media/movies-4k) + `TV - 4K` (/data/media/tv-4k),
not merged into the 1080p libraries.
- **Traefik**: file-provider routers (see traefik-router snippet), NOT docker labels.
- **Tdarr**: does NOT watch movies-4k/tv-4k (its libraries are the specific 1080p /media/movies,
/media/tv) — quality-first keeps the grabbed file.
## Deferred (Step 2 — gated)
Recyclarr 4K config + quality profiles (custom formats, remux tiers). NOT deployed yet.
The Overseerr 4K servers currently point at the default `Ultra-HD` profile as a placeholder.
