## Description

Subarr is a coordination service that sits alongside Bazarr in the *arr media automation stack. It analyzes your media library to determine which subtitles are actually missing, verifies audio languages by sampling multiple chunks of each file with Whisper, and schedules transcription jobs to subgen (a patched Whisper worker) with backpressure and priority signals from Tautulli. It provides a web UI with dashboard, coverage gap analysis, queue management, library browser, audio-language review with an audio player, a Whisper tuning lab for per-language model optimization, and provenance tracking of which provider delivered each subtitle. It integrates with Sonarr, Radarr, Bazarr, Plex, Jellyfin, Tautulli, and optionally Ollama for AI enrichment. Runs as a non-root Docker container with SQLite storage on a persistent volume. Authentication is enabled by default with a single admin account, API keys, and reverse-proxy support.
