# PURPOSE
# ─────────────────────────────────────────────────────────────────────────────
# Delete orphaned movie files not tracked by Radarr. Queries the API for all
# tracked movie file paths, walks the library on disk, and removes anything
# untracked that is old enough to be past the import window. Triggers an Emby
# library clean after each deletion run so ghost entries disappear immediately.
#
# The tracked-count floor check (Safety Layer 6) is rescan-aware: if Radarr's own
# RescanMovie/DownloadedMoviesScan is active (independently of this script's own
# lighter ProcessMonitoredDownloads pre-flight), a genuinely low mid-scan count gets
# waited out (calibrated to that command's historical duration via
# arr_get_rescan_duration(), up to 3 strikes) and re-fetched rather than triggering a
# false-alarm abort. Mirrors the same fix built for lidarr_cleanup.sh 2026-07-16 after
# a whole-library rescan there made trackFileCount read 22% of normal mid-scan.
#
# Cache-first movie list (2026-07-17), batched moviefile fetch (2026-07-19). The movie list
# comes from the shared tracked-data cache via arr_get_tracked_data() — fresh (kept warm
# every 30min by arr_cache_prefill.sh), live fetch as fallback. Radarr's movie list embeds
# movieFile.path directly on every hasFile=true entry, but that's only the *primary* file —
# Radarr 6+ supports a second tracked file per movie (alternate editions/extras) that never
# shows up there, so relying on it alone misclassified a movie's second edition as an orphan
# (confirmed live 2026-07-19: The Crash, They Will Kill You, The Drama, Lee Cronin's The
# Mummy, and Ready or Not: Here I Come all had a legitimately-tracked second file deleted-flagged
# this way). /moviefile?movieId=X returns every file for a movie, including secondaries, and
# accepts movieId as a repeated query param for a bulk fetch — but the whole library in one
# request 414s (Request-URI Too Long, confirmed live), so _fetch_tracked_files() batches
# movieId params BATCH_SIZE at a time instead: ~14 requests for a ~2800-movie library rather
# than the up-to-2896 individual per-movie calls the 2026-07-17 optimization eliminated, and
# rather than the one-shot list read that missed secondary files. The filesystem is walked
# once per run, not twice — classification records which paths are eligible for deletion as
# it goes, and the delete pass (once the size-threshold check below passes) just acts on that
# list instead of re-walking and re-classifying the whole tree. That single walk also gets
# size+mtime straight from find -printf instead of a separate stat fork per file — find
# already has to stat() every entry to know it's -type f, so this is free by comparison.
# Measured ~130x faster per file (0.033ms vs 4.3ms).
#
# ==============================================================================================
# OPERATIONAL MODEL
# ==============================================================================================
#
# Every file encountered on disk is classified into one of five categories:
#
#   TRACKED   — Radarr API knows this exact path → leave it alone
#   PROTECTED — matches RADARR_PROTECTED_PATTERNS → never delete
#   ORPHAN    — video file, not tracked, older than RADARR_ORPHAN_AGE → delete
#   JUNK      — not a video extension, not protected → delete regardless of age
#   RECENT    — not tracked, under RADARR_ORPHAN_AGE → skip (may be mid-import)
#
# 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 PROTECTED classification these would be deleted — breaking Radarr and
# Emby metadata display.
#
# After deletions: notify_emby_scan() triggers Emby "Clean Missing Files" task.
# Emby removes ghost entries immediately — no user-facing file-not-found errors.
#
# ==============================================================================================
# DESIGN PRINCIPLES
# ==============================================================================================
#
# API as Ground Truth
#   What Radarr tracks is authoritative. Files not in the API response are
#   orphans — Radarr has no record of them and they serve no purpose.
#   The script never infers ownership from directory structure alone.
#
# Age Gate Before Deletion
#   Files under RADARR_ORPHAN_AGE are left alone regardless of tracked status.
#   Radarr's import pipeline writes files before registering them — acting
#   immediately would delete files mid-import.
#
# Emby Cleanup Is Part of the Job
#   Deleting a file without telling Emby leaves ghost entries that show as
#   broken items. Triggering the Emby clean is not optional — it completes
#   the deletion from the user's perspective.
#
# ==============================================================================================
# OPERATIONAL SAFEGUARDS
# ==============================================================================================
#
# Seven gates — ALL must pass before any file is touched:
#   1. Container running and not starting/unhealthy
#   2. API reachable
#   3. API version matches RADARR_VERSION_MAJOR in master.conf
#   4. Movie count > 0
#   5. Tracked file count > 0
#   6. Tracked count >= RADARR_MIN_TRACKED_PCT % of last known count
#   7. Deletion size < RADARR_MAX_DELETE_GB — or --i-know-what-im-doing required
#
#   acquire_lock "wait"  — large scans take time, wait for previous run to finish
#   jq + curl validation — exits if either tool missing
#   ARR_DOCKER_TIMEOUT   — container checks protected against daemon hangs (script-local, not common.sh's DOCKER_TIMEOUT)
#   notify_emby_scan()   — triggers Emby clean after deletion
#   platform_require_cmd  — notify script validated before use
#   Silent by default    — orphans/junk warn(), clean library logs silently
#
# ==============================================================================================
# STATE FILES
# ==============================================================================================
#
#   RADARR_TRACKED_COUNT_FILE — persistent baseline for the tracked % safety check (gate 6)
#       Updated after each successful run. Protects against misconfigured root path
#       returning an empty API response and deleting the entire library.
#
# ==============================================================================================
# CONFIGURATION
# ==============================================================================================
#
# 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
#
# 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_MIN_TRACKED_PCT     — abort if tracked count drops below this % of last run
#   RADARR_TRACKED_COUNT_FILE  — persistent baseline file path
#   RADARR_EXTENSIONS          — video file extensions 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)
