Comment-only. Headers on the scripts touched during today's caching work
(cache-first fetches, write-through per-item cache, single-walk
consolidation, movieFile-embedded fix) still described pre-change
behavior. Also brought common.sh's top-level cache doc block current --
it was written for the single-consumer 2026-07-16 state and didn't
mention the tmpfs move, the write guard, or the 15+ consumers that now
go through it.
Every script that fetches the full Lidarr/Sonarr/Radarr tracked-library
list now goes through arr_get_tracked_data() instead of hitting the API
directly -- cache-first when fresh, live fetch as fallback when stale,
waits out an active rescan before either. Per-item file data (trackFile/
episodefile/moviefile) stays live-only everywhere, since that's the
actual disk-truth these scripts' decisions depend on and was never part
of what's cached.
Also adds arr_cache_prefill.sh to CRITICAL_MAINTENANCE_SCRIPTS (30min
tier) with a short 1min wait ceiling, so the cache stays consistently
fresh instead of only refreshing whenever some other script happens to
write through. A full cache refresh for all three arrs measured at ~12s
total live -- nothing like the multi-hour cost of an actual rescan.
common.sh gains:
- docker_cmd() + verify_running() + retry_docker() — removed from all 3 Docker_Essentials
scripts where they were byte-for-byte duplicates
- emby_api(endpoint, [timeout=30]) — removed from 6 Media/Tools scripts that each defined
their own _emby_api() with the same curl/parse/error pattern; call sites renamed emby_api
- format_duration() extended with days/hours branch (was capped at minutes+seconds)
- notify() comment: scripts do not need to preflight the notify script via validate_unraid_cmd
Tailscale deduplication:
- arr_sync.sh: _resolve_node_ip() and inline block in _delete_remote_item() both replaced
with resolve_tailscale_ip() from common.sh
- git_pull_execute.sh: inline tailscale ip -4 replaced with resolve_tailscale_ip() (adds
the tailscale status fallback that was missing)
master.conf:
- reorder ORCHESTRATORS section by run frequency; add missing entries
- remove heartbeat vars (watchdogs no longer run in continuous cycle)
- remove dead REMOTE_DOCKER_RETRY_WAIT and display-only watchdog interval vars
- move INTERMEDIATE_RSYNC_ENABLED into RSYNC two-tier block; reorder by frequency
common.sh:
- add missing info() and success() definitions — both were called throughout but never defined
- update output tier description to list all 5 functions
- fix double-icon in check_local_disk_temps() error/warn calls
- fix smashed curl/ssh command lines in notify_emby_scan() and check_remote_docker_daemon()
- update check_rsync_enabled() comment to include INTERMEDIATE, ordered by frequency
emby_to_radarr_sync.sh / emby_to_sonarr_sync.sh:
- wire up RADARR_EMBY_LIBRARIES / SONARR_EMBY_LIBRARIES; empty array now scans all libraries
No setup banners to remove (Tools folder was already clean). Fix log→echo
on summary status/conclusion lines across container_data_export, emby_database_repair,
recreate_shares, zfs_pool_scrub, and fallback_state_reset (safety check + two summary
detail lines). Fix log→echo on status display lines in watchdog_skip_list_manager
(skip list empty, restart history lines). Move per-item "to add" preview echoes to
log in emby_to_lidarr/radarr/sonarr_sync; fix nothing-to-do log→echo in all three.
Add output tiers section to Manual-Tools.md.
Script headers (6 files):
- Add OPERATIONAL SAFEGUARDS section to all discovery + emby sync scripts
- Add STATE FILES section to all 3 discovery scripts
- Add CONFIGURATION section to emby_to_*_sync.sh
- Rename USAGE → RUNTIME MODES in emby_to_*_sync.sh (doc standard)
- Fix SONARR_DISCOVERY_MONITOR_MODE default doc: "future" → "all"
Media/README-Media.md:
- Remove "WIP prototype" label; describe all 3 discovery scripts
- Add discovery scripts to scripts table and HOW THE SCRIPTS RELATE diagram
- Add weekly discovery schedule block to EXECUTION ORDER section
- Update intro to mention behavior-driven discovery
Media/Manual-Media.md:
- Add configuration reference sections for all 3 discovery scripts
- Add flag reference sections for all 3 discovery scripts
Tools/README-Tools.md:
- Add "Library Sync Bootstrap" category and emby_to_*_sync.sh to scripts table
- Add emby sync scripts to HOW THE SCRIPTS RELATE diagram
Tools/Manual-Tools.md:
- Update emby sync notes: search commands now fire immediately after add
README.md:
- Update Media folder description to include discovery
- Update weekly schedule to show discovery scripts
- Update README table entry for Media
- New: Media/playback_aware_sonarr_discovery.sh — two-stage TV show
discovery using Emby episode play history → TMDB TV recommendations.
Multi-user aware: diversity score (0-50) is primary seed driver so one
user binge-watching alone cannot dominate. Per-user episode cap (default 8)
limits single-user volume contribution. TMDB→TVDB via external_ids for
reliable Sonarr lookup. monitor=future by default.
- Add to WEEKLY_MAINTENANCE_SCRIPTS; Sonarr discovery config block in
master.conf (threshold=52, lookback=14d, max_adds=3, user_ep_cap=8).
- Fix: all arr add scripts were not triggering searches after adding.
Added _radarr_command/_lidarr_command/_sonarr_command helpers and fire
MoviesSearch/ArtistSearch/SeriesSearch immediately after each successful
add. Affects: playback_aware_radarr_discovery.sh, emby_to_lidarr_sync.sh,
emby_to_radarr_sync.sh, emby_to_sonarr_sync.sh.
- playback_aware_radarr_discovery.sh: new two-stage movie discovery
using recently watched Emby movies as seeds and TMDB recommendations
as the similarity engine; scores on recency + rating + vote count;
adds HOST*_TMDB_API_KEY alias to detect_hosts() in common.sh
- emby_to_sonarr_sync.sh: restrict to SONARR_EMBY_LIBRARIES allowlist
(Anime, Kids Shows, Stand-Up Comedy, TV shows) — excludes Youtube
and Recorded Sports libraries; add garbage title filter for multi-
season folder names (S01-S03) and bare bracket tags ([Prof])
- emby_to_radarr_sync.sh: add _is_episode_title filter to block anime
episode files stored in Movies library (underscore/dot patterns,
fansub bracket format, episode markers, codec metadata strings)
- emby_to_lidarr_sync.sh: add U+FFFD Unicode replacement character
filter alongside the existing ASCII ? filter for encoding corruption
- master.conf: RADARR_DISCOVERY_* settings, SONARR/RADARR_EMBY_LIBRARIES
allowlists, Radarr discovery added to WEEKLY_MAINTENANCE_SCRIPTS
Lidarr Discovery (playback_aware_lidarr_discovery.sh):
- Complete rewrite to two-stage pipeline: Stage 1 scores weekly Emby
plays → top seeds; Stage 2 runs Last.fm getSimilar on seeds → scores
candidates → adds top 0-5 to Lidarr
- Per-user influence cap (35%) prevents single listener dominating discovery
- Requires 2+ seeds to accept a candidate (single-seed skipped)
- Last.fm similarity limit 10 for tighter, higher-quality candidates
- 30-day reject cooldown history; MAX_ADDS=5 cap enforced
- Root folder fetched from Lidarr API at runtime (no config path)
- Added to WEEKLY_MAINTENANCE_SCRIPTS (uncommented)
Emby→arr sync tools (Tools/):
- emby_to_lidarr_sync.sh: finds Emby music artists not in Lidarr, adds them
- Dirty tag filter: comma-list, feat./ft., &, vs, " - " patterns skipped
- Root folder fetched from Lidarr API at runtime
- emby_to_sonarr_sync.sh: finds Emby series not in Sonarr, adds them
- TVDB ID matching with title fallback
- emby_to_radarr_sync.sh: finds Emby movies not in Radarr, adds them
- TMDB ID matching with title fallback
- All three: searchForMissing*: false (monitoring only, no searches triggered)
- All three documented in Tools/Manual-Tools.md
