# PURPOSE
# ─────────────────────────────────────────────────────────────────────────────
# Delete orphaned TV episode files not tracked by Sonarr. Queries the API for
# all tracked episode 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 Sonarr's own
# RescanSeries/DownloadedEpisodesScan is active (independently of this script's own
# lighter ProcessMonitoredDownloads pre-flight — e.g. during a large missing-episode
# search campaign), 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, both layers (2026-07-17). The series list itself 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. The per-series episodefile walk below still
# always fetches live (that's the actual disk-truth this script's delete decisions depend
# on), but write-throughs its result to arr_item_cache_write() for any future script that
# needs Sonarr's per-episode data — no second consumer exists yet, unlike Lidarr's
# lidarr_missing_art.sh, but the data's there once one does. 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   — Sonarr API knows this exact path → leave it alone
#   PROTECTED — matches SONARR_PROTECTED_PATTERNS → never delete
#   ORPHAN    — video file, not tracked, older than SONARR_ORPHAN_AGE → delete
#   JUNK      — not a video extension, not protected → delete regardless of age
#   RECENT    — not tracked, under SONARR_ORPHAN_AGE → skip (may be mid-import)
#
# Sonarr generates show 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 Sonarr 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 Sonarr tracks is authoritative. Files not in the API response are
#   orphans — Sonarr 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 SONARR_ORPHAN_AGE are left alone regardless of tracked status.
#   Sonarr'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 SONARR_VERSION_MAJOR in master.conf
#   4. Series count > 0
#   5. Tracked file count > 0
#   6. Tracked count >= SONARR_MIN_TRACKED_PCT % of last known count
#   7. Deletion size < SONARR_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
# ==============================================================================================
#
#   SONARR_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*_SONARR_URL / HOST*_SONARR_API_KEY / HOST*_SONARR_TV_ROOT
#   HOST*_SONARR_PATH_MAP — container path → host path translation
#   All aliased by detect_hosts() — script uses unprefixed names
#
# master.conf
#
#   SONARR_ORPHAN_AGE          — days before untracked file eligible for deletion
#   SONARR_MAX_DELETE_GB       — require --i-know-what-im-doing above this
#   SONARR_MIN_TRACKED_PCT     — abort if tracked count drops below this % of last run
#   SONARR_TRACKED_COUNT_FILE  — persistent baseline file path
#   SONARR_EXTENSIONS          — video file extensions for orphan classification
#   SONARR_PROTECTED_PATTERNS  — file patterns never deleted
#   SONARR_VERSION_MAJOR       — expected Sonarr major version for API safety check
#   SONARR_IMPORT_SCAN_TIMEOUT — seconds to wait for pre-flight import scan (default 600)
#   ARR_CLEANUP_STATS          — stats file path (read by coffee report)
