# ================================= Radarr Cleanup =============================================
# ==============================================================================================
# Removes orphaned movie files from the library that Radarr no longer tracks.
# Uses the Radarr API to build a complete list of tracked movie file paths then compares
# against what exists on disk — anything untracked and older than RADARR_ORPHAN_AGE
# days is considered an orphan and deleted.
#
# ── FILE CLASSIFICATION ───────────────────────────────────────────────────────────────────────
#   TRACKED   — Radarr API knows about this exact file path → leave it alone
#   PROTECTED — matches RADARR_PROTECTED_PATTERNS → never delete (artwork, subtitles, .nfo)
#   ORPHAN    — video file, not tracked, older than RADARR_ORPHAN_AGE days → delete
#   JUNK      — not a video extension, not protected → delete regardless of age
#   RECENT    — not tracked, under RADARR_ORPHAN_AGE days old → skip (may be mid-import)
#
# ── WHY PROTECTED PATTERNS MATTER ─────────────────────────────────────────────────────────────
# Radarr generates movie artwork (*.jpg), metadata (*.nfo) and manages subtitles (*.srt,
# *.sub, *.ass) but does NOT include these in its tracked file API response.
# Without protection these would be classified as orphans and deleted — breaking
# Radarr and Emby metadata display.
#
# ── SAFETY LAYERS — ALL MUST PASS BEFORE ANY FILE IS TOUCHED ─────────────────────────────────
#   1. Container must be running and not starting/unhealthy
#   2. API must be reachable
#   3. API version must match tested major version in master.conf
#   4. Movie count must be > 0
#   5. Tracked file count must be > 0
#   6. Deletion size must be < RADARR_MAX_DELETE_GB — or --i-know-what-im-doing required
#
# ── POST-DELETION ─────────────────────────────────────────────────────────────────────────────
# After files are deleted notify_emby_scan() triggers Emby "Clean Missing Files" task.
# Emby immediately removes ghost entries — no user-facing file-not-found errors.
#
# ── OVERRIDE FLAGS ────────────────────────────────────────────────────────────────────────────
# --i-know-what-im-doing   required when deletion exceeds RADARR_MAX_DELETE_GB
# --skip-strike-list       bypasses RADARR_ORPHAN_AGE age check
# NUCLEAR MODE — both active: age + size bypass, deletes on first pass
#   ⚠️  User accepts full responsibility — no recovery possible after deletion
#
# ── HOST AWARENESS ────────────────────────────────────────────────────────────────────────────
# HOST1 Radarr manages Movies. HOST2 Radarr manages Anime_Movies.
# detect_hosts() sets MY_ID and aliases RADARR_URL, RADARR_API_KEY, RADARR_MOVIES_ROOT.
# No manual HOST1/HOST2 comparisons — MY_ID routes correctly on any server.
#
# ── SAFEGUARDS ────────────────────────────────────────────────────────────────────────────────
#   acquire_lock "wait"  — large scans take time, wait for previous run to finish
#   jq + curl validation — exits if either tool missing
#   DOCKER_TIMEOUT       — container checks protected against daemon hangs
#   6 safety layers      — all must pass before any file is touched
#   notify_emby_scan()   — triggers Emby clean after deletion
#   validate_unraid_cmd  — notify script validated before use
#   Silent by default    — orphans/junk warn(), clean library logs silently
#
# ── CONFIGURATION (master_host*.conf) ─────────────────────────────────────────────────────────
#   HOST*_RADARR_URL / HOST*_RADARR_API_KEY / HOST*_RADARR_MOVIES_ROOT
#   HOST*_RADARR_PATH_MAP — container path → host path translation
#   All aliased by detect_hosts() — script uses unprefixed names
#
# ── CONFIGURATION (master.conf) ───────────────────────────────────────────────────────────────
#   RADARR_ORPHAN_AGE            — days before untracked file eligible for deletion
#   RADARR_MAX_DELETE_GB         — require --i-know-what-im-doing above this
#   RADARR_EXTENSIONS            — video file extensions considered for orphan classification
#   RADARR_PROTECTED_PATTERNS    — file patterns never deleted
#   RADARR_VERSION_MAJOR         — expected Radarr major version for API safety check
#   RADARR_IMPORT_SCAN_TIMEOUT   — seconds to wait for pre-flight import scan (default 600)
#   ARR_CLEANUP_STATS            — stats file path (read by coffee report)
#
