Add Lidarr tracked-data cache + duplicate artist cleanup
Shared cache (lidarr_get_tracked_data() in common.sh) so scripts stop hitting Lidarr's live API for tracked counts every run, and stop treating a mid-rescan dip as a genuine problem — a whole-library RescanFolders legitimately makes trackFileCount read far below normal while it re-verifies every file (confirmed 2026-07-16: 22% of normal mid-scan). Cache reads fresh-if-recent, waits out an active rescan (calibrated to that command's own historical duration, tracked per command name since RescanFolders and DownloadedAlbumsScan take wildly different amounts of time), then falls back to a stale cache rather than hard-failing after a few strikes. lidarr_cleanup.sh: no longer stacks a fresh DownloadedAlbumsScan on top of one already running, and the tracked-count floor check now waits out a genuine rescan instead of aborting on every overlap. lidarr_duplicate_artist_cleanup.sh (new): finds case-insensitive duplicate artist entries — same display name, different MusicBrainz ID, added when a search/list-sync matches the wrong same-named artist. Deletes the empty phantom side and blocks it from Import List Exclusions, leaves genuinely-different-real-artists alone (checked by album title overlap, deduped per-artist first so a legitimate reissue under an artist's own catalog doesn't false-flag as cross-artist overlap), and only notifies for the rare case where both sides have real, overlapping content. lidarr_cache_prefill.sh (new): warms the cache at array start so nothing reads it cold after boot. lidarr_missing_art.sh, lidarr_release_fixer.sh: write-through the cache as a side effect of fetches they already needed for their own purposes.

# PURPOSE
|
||||
# ─────────────────────────────────────────────────────────────────────────────
|
||||
# Populates the shared Lidarr tracked-data cache (see lidarr_get_tracked_data() in common.sh)
|
||||
# once at array start, before any other script needs it. Without this, the cache stays cold
|
||||
# from boot until whichever Lidarr-touching script happens to run first and write through —
|
||||
# which could be hours, depending on the daily schedule. One-shot: runs and exits.

||||
#

||||
# ==============================================================================================
|
||||
# OPERATIONAL MODEL
|
||||
# ==============================================================================================
|
||||
#
|

# Lidarr's container may still be starting when this fires (array just started) — retries
|
||||
# reaching the API for up to LIDARR_PREFILL_WAIT_MINUTES before giving up. Not fatal if it
|
||||
# never comes up in time; the cache just stays cold until the next script writes through
|
||||
# naturally, exactly as it would without this script existing at all.

#
|
||||
# PURPOSE
|
||||
# ─────────────────────────────────────────────────────────────────────────────
|
||||
# Detects and resolves duplicate artist entries in Lidarr's library — cases where the
|
||||
# same display name (case-insensitive) is backed by two different MusicBrainz artist
|
||||
# IDs. This happens when a search or list sync matches a same-named-but-different real
|
||||
# artist and adds it alongside the one already in the library. From that point on,
|
||||
# every completed download for that display name throws MultipleArtistsFoundException
|
||||
# and can never import — Lidarr correctly refuses to guess which of the two it means.
|
||||
#
|
||||
# ==============================================================================================
|
||||
# OPERATIONAL MODEL
|
||||
# ==============================================================================================
|
||||
#
|
||||
# For each case-insensitive duplicate artist name found:
|
||||
#
|
||||
# Only one side has any tracked files
|
||||
# → The zero-file side is a phantom — delete it (deleteFiles=false, nothing on disk
|
||||
# to lose) and add its MusicBrainz ID to Lidarr's Import List Exclusions so it
|
||||
# can't be silently re-added by a future list sync. Then trigger a refresh on the
|
||||
# surviving artist so anything that was stuck on this exact ambiguity resolves
|
||||
# immediately instead of waiting for Lidarr's own next check cycle.
|
||||
#
|
||||
# Both sides have files, but their album titles don't overlap at all
|
||||
# → Genuinely two different real artists sharing a name (e.g. a band's classic
|
||||
# lineup vs. a later solo era with the same stage name). Not a bug — left alone.
|
||||
#
|
||||
# Both sides have files AND overlapping album titles
|
||||
# → The one case actually risky to automate: could mean real content is split
|
||||
# across two entries and needs an actual merge, not a delete. Untouched,
|
||||
# notified for manual review.
|
||||
#
|
||||
# ==============================================================================================
|
||||
# DESIGN PRINCIPLES
|
||||
# ==============================================================================================
|
||||
#
|
||||
# Never Delete Real Content
|
||||
# Only the zero-tracked-file side of a pair is ever deleted. Anything with files is
|
||||
# either left alone (disjoint albums) or flagged for a human (overlapping albums) —
|
||||
# never auto-removed.
|
||||
#
|
||||
# Block Re-Addition At The Source
|
||||
# A phantom that keeps coming back is worse than one that was never cleaned —
|
||||
# Import List Exclusion is Lidarr's own mechanism for "never auto-add this again."
|
||||
#
|
||||
# Silent When Clean
|
||||
# No duplicates found, or all duplicates are the simple phantom case — minimal
|
||||
# output. Only ambiguous (overlapping-album) pairs produce a notification.
