Diagnose setup issues and suggest fixes.

Usage

mithrandir doctor

Runs a comprehensive set of diagnostic checks grouped by category:

System — .env file exists, Docker installed and running, swap configured, firewall rules, and Tailscale (when enabled): installed, tailscaled running, connected to the tailnet, subnet routes / exit node awaiting approval, device key expiring within 14 days
Apps — containers running, config directories exist, required secrets present
Media (when qBittorrent and Radarr/Sonarr/Lidarr are installed) — download categories, hardlinks and the cleanup webhook are configured, and how much space unused downloads take (see media)
Backup — backup directory exists, systemd service and timer installed, rclone configured and remote reachable

Each failing check includes a hint on how to fix the issue.

Returns exit code 1 if any check fails, 0 if all pass.
