# Run it by hand, over SSH, when material has accumulated in {{ navidrome_incoming_dir }}:
#     beet import {{ navidrome_incoming_dir }}

# It is interactive on purpose. `beet import -q` auto-applies only strong
# matches and leaves the rest where they are, which makes a usable review queue
# if the batches ever get boring.

# track into its own phantom artist, which is how a library ends up with four
# hundred one-album artists and Navidrome gets blamed for it.

# THE trap this library is exposed to, and the fix for it.
#
# beets MOVES files into place, and rename(2) preserves the original group and
# mode - so the setgid bit on {{ navidrome_music_dir }} does NOT apply to them
# (it only affects files CREATED there, such as the album directories beets
# makes, which do come out group-{{ navidrome_group }}). A track that arrives
# mode 0600 therefore lands mode 0600 owned by the curator's own group, and
# Navidrome cannot read it. It does not error: the track is simply ABSENT from
# the library, which is indistinguishable from never having imported it.
#
# Measured on this box: a 0600 file was unreadable by the navidrome user; the
# same file at 0644 was fine. So normalise every imported file.
# NO leading zeros. The plugin does int(str(value), 8), and YAML would parse
# `0644` as octal -> decimal 420, which the plugin then re-reads as octal 0o420.
# Verified on the box: `0644` silently left a 0600 file at 0600; `644` fixes it.
