# 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.

## Step 2 — Recyclarr 4K (DONE)
`deploy-recyclarr-4k.yml` (recyclarr image :8, config uses !env_var, .env from ansible-vault).
Sync runs via **systemd timer** `recyclarr-4k-sync.timer` (daily 04:00, docker-run oneshot — NOT
container cron). Profiles applied: radarr-4k = **Remux + WEB 2160p** (fd161a61), sonarr-4k =
**WEB-2160p** (d1498e7d), assigned to the Overseerr 4K servers (replaced Ultra-HD placeholder).
**DTS family explicitly pinned score 0** (Sonos-Arc down-weight; re-forced every sync so it can't
revert to guide 2500/4500) — Dolby/TrueHD/Atmos left at guide default (positive).
