# ================================= Sonarr Cleanup =============================================
# ==============================================================================================
#
# 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.
#
# ==============================================================================================
# 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
# ==============================================================================================
#
# Six 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. 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
#   DOCKER_TIMEOUT       — container checks protected against daemon hangs
#   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
#
# ==============================================================================================
# 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_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)
