Moves all ~30 pipeline scripts, configs, and the vendored sldl binary into this repo (source /opt/sldl left untouched). Removes all docker exec/docker compose dependencies now that beets and sldl run in-process/as a subprocess of this container instead of via soulbeet/on-demand sldl containers. Replaces hardcoded host paths, Navidrome credentials, and Spotify credential sourcing with env-var-driven paths and shared credential loaders. Adds Dockerfile, entrypoint.sh, requirements.txt, docker-compose.snippet.yml, and the initial app DB schema.

# navidrome-scan.sh — trigger a Navidrome full scan ONLY if the music library
|
|
# share is healthy.
|
|
#
|
|
# Why this exists: with ND_SCANNER_PURGEMISSING=always (which we keep, so
|
|
# on-disk deletions propagate to playlists and out to Traktor), a full scan
|
|
# that runs while the QNAP NFS share is unavailable makes Navidrome see the
|
|
# entire library as "missing" and purge it — wiping every playlist. That is
|
|
# exactly what happened on 2026-06-01 and lost the manual dj-* playlists.
|
|
#
|
|
# This wrapper refuses to trigger the scan unless the share is mounted, a
|
|
# canary file is readable, and the library has a sane number of artist dirs.
|
|
# Skipping a scan is harmless (the next healthy run picks up changes); running
|
|
# one against a dead mount is catastrophic.
