NPM's access log only describes hosts somebody visited; the host most likely to be quietly broken
is the one nobody does. Probes carry a User-Agent npm_access_stats.sh drops — unmarked, this
monitor would be fifty thousand requests a day in the very logs it reports on.
The memory warning used plain system-wide 'free' RAM (via free -g), a
carryover from before this script was ZFS-specific. ZFS ARC deliberately
consumes most otherwise-unused RAM, so 'free' being low is normal and not
a meaningful signal — it fired a false alarm on 2026-07-05 (free 5.8Gi,
but available a healthy 45Gi).
Replaced ZFS_REPORT_FREE_WARN_GB with ZFS_REPORT_ARC_FREE_WARN_GB: warns
when ARC headroom (ARC_MAX - ARC_CURRENT) drops below threshold, which is
what actually indicates ARC is running out of room to grow. Available RAM
check is unchanged — it's a legitimate system-pressure signal on its own.
Codebase-wide audit pass: fixed real bugs (SSH hangs missing BatchMode,
local-outside-function no-ops, variable name collisions, a truncated
ratio calc, wrong state-dir path, DARK vs NO_INTERNET drift, and more),
then pulled logic that was duplicated across multiple scripts — arr
cleanup safety gates, docker restart ordering, container maintenance
stop/restart, watchdog state-file helpers, partnership role resolution,
cert expiry checks, remote node discovery, and TMDB discovery scoring —
into common.sh so each now has a single implementation.
Same audit as the orchestrator standardization pass (2a062e5), extended to
every remaining script. Found the same class of bug independently recurring:
ramdisk_stop.sh checked $LOG (nothing assigns it, should be $ENABLE_LOGGING),
partnership_onboard.sh checked $LOG_MODE (same issue), emby_session_report.sh
checked $TRANSCODE_PCT which was never computed so the high-transcode alert
could never fire, and storage_migrate.sh never called detect_hosts() so
$MY_ID was empty, silently breaking the post-migration host*.conf update.
partnership_manager.sh used `local` at top-level script scope (invalid outside
a function) and had two master.conf path references missing "Configurations/".
Along the way: several scripts (share_setup.sh, conf_sync.sh,
downloaders_reset.sh, transcode_cleanup.sh, transcode_manager.sh,
remote_arr_cache_writer.sh, upgrade_webhook_handler.sh) had no explicit
trailing exit code, so they always reported success regardless of real
failures. play_state_sync.sh was missing the partnership gate its own header
documented, so remote play-state sync ran even with PARTNERSHIP_ENABLED=false;
it also always exited 0 on sync errors. arr_profile_enforcer.sh and
webhook_setup.sh hand-rolled their own flag parsing instead of common.sh's
parse_args, so --log silently did nothing on either.
system_watchdog.sh was itself an un-standardized mini-orchestrator — converted
to the shared run_orch_child()/JOB_PASS/JOB_FAIL pattern, added the missing
failure notification, and fixed dry-run to pass --dry-run down to children
instead of skipping them outright. Also fixed a stale webgui_watchdog.sh path
in master.conf.template that would break system_watchdog.sh on any fresh
install.
Closed a sibling-drift gap: radarr_cleanup.sh and sonarr_cleanup.sh were
missing lidarr_cleanup.sh's tracked-count percentage-drop safety gate and its
"not configured on this host, skip cleanly" guard — both now match Lidarr's
7-gate model.
Every script now has the established header format: PURPOSE with ─────── separator,
OPERATIONAL MODEL, DESIGN PRINCIPLES, OPERATIONAL SAFEGUARDS, CONFIGURATION, and
RUNTIME MODES — structured with full ====== banner sections throughout.
Orchestrators converted from compact ── inline format to full banners. Stale
emby-fallback and dirty sync references removed from Plugin/user_script_plug-in.sh.
All state/data file paths in scripts and PHP now resolve via STATE_DIR / DATA_DIR /
PERSISTENT_CONF_CACHE instead of hardcoded /boot/config/ or /tmp/ paths, so the
ecosystem works in both internal and appdata storage modes.
PHP layer (watchdog.php, partnership.php, fallback.php, monitor.php, snapshot.php,
config.php): all state reads switched to STATE_DIR constant; remote state reads use
the new vv_remote_state_cmd() helper which resolves the remote's SCRIPTS_DIR via
their varaverk.cfg before building the path.
conf_sync.sh: fixed SCRIPTS_ROOT → SCRIPTS_DIR bug on MY_CONF path; added
_remote_scripts_dir() to resolve partner's SCRIPTS_DIR before SCP pull.
fallback.php page: added controls card (PARTNERSHIP_ENABLED, FALLBACK_ENABLED,
FALLBACK_RSYNC_ENABLED toggles), status grid, and settings card.
README and Manual updated for System_Essentials, Watchdogs, Fallback, Rsync,
Media, Monitors, Orchestrators, Partnership: added new scripts (conf_sync,
conf_cache_save/restore, conf_cache_watchdog, play_state_sync, start_webhook_listener,
upgrade_webhook_handler), corrected all stale /boot/config/ state file paths to
$STATE_DIR/$DATA_DIR, noted webgui/php_fpm/mover/user_scripts scripts moved to
Plugin/unraid/System_Essentials, fixed start_webhook_listener.sh header (Node.js,
not PHP -S).
Adds require_partnership() to common.sh — exits cleanly when PARTNERSHIP_ENABLED=false.
Removes FALLBACK_PARTNERSHIP_REQUIRED toggle — partnership is now always required,
not optional. Cross-server scripts (rsync, conf sync, fallback, arr sync, play state,
backup verify) all call require_partnership after detect_hosts.
All FALLBACK_${MY_ID}_COVERS_${REMOTE_ID}_TIER* references updated to
FALLBACK_${REMOTE_ID}_TIER* across fallback_test.sh, partnership_manager.sh,
docker_update.sh, mesh_monitor.sh, and monitor.php. mesh_monitor.sh drops
the inner covering-host loop — tier data now lives in the covered host's own
conf so no cross-host scan is needed. monitor.php reads from the covered
host's conf file rather than the local host's.
Behavior fixes:
- docker_daily_restart.sh: implement RESTART_VERIFY_WAIT sleep before
verify_running() — variable was logged as config but never applied
- cert_monitor.sh: --log now shows expiry date and days remaining for
healthy domains in the per-domain summary; problems always show details
Header corrections:
- downloaders_reset.sh: fix frequency contradiction (15 min → 30 min)
- lidarr_cleanup.sh: Emby scan triggers on actual deletions, not every run
- ssh_setup.sh: document --local-only flag in USAGE section
- zfs_memory_snapshot.sh: clarify dry-run skips log write in PURPOSE
- ramdisk_stop.sh / ramdisk_setup.sh: document TRANSCODE_STATE_FILE var
- smart_long_test.sh: remove SMART_TEMP_WARN/CRIT — not used in code
stability_watchdog.sh mover check now uses platform_is_mover_running()
instead of raw pgrep, matching server_reboot.sh.
check_unraid_version_parity() renamed to check_os_version_parity() —
the function internals were already platform-neutral after the adapter
refactor; the name was the last Unraid artifact.
All bash scripts are now platform-neutral. Unraid-specific paths, commands,
and service checks moved to Plugin/unraid/adapter.sh. Core scripts call
platform_*() functions exclusively — no direct OS paths in runtime logic.
New adapter functions: platform_storage_path, platform_webui_install_path,
platform_scripts_dir_probe_cmd, platform_setup_db_path, platform_storage_healthy,
platform_is_service_enabled, platform_get_temp_thresholds, platform_disk_states_path,
platform_rebuild_container, platform_push_conf, platform_push_setup_state,
platform_get_templates_dir, platform_send_os_notification.
Partnership services stack (Emby/Jellyfin/Seerr/SeerrFin) added as third
onboarding stack alongside auth and arr stacks.
- Auth stack: fold cert monitor into Auth Stack page as fourth tab (Certs);
remove standalone cert page and top-level tab
- cert_monitor.sh: write JSON status cache to State_Files/cert_status.json
after each run; expose per-domain days/expiry via _CERT_DAYS/_CERT_EXPIRY globals
- api/cert.php: new — serves cached cert status; falls back to configured
domains as UNKN when no cache exists; POST action=run triggers live check
- arrs db fallbacks: vv_arr_cleanup_stats/discovery_stats/recovery_stats now
read from data/*.db files when log JSON files don't yet exist
- config.php vv_conf_vars(): unescape bash \$ → $ so passwords with dollar
signs read correctly from conf files
- host1.conf: fill in HOST1_NPM_USER/PASS and HOST1_LLDAP_USER/PASS
- Partnership adapter pattern: Unraid-specific container logic extracted to
Plugin/unraid/Partnership/; platform-agnostic structure stays in Partnership/
- First-run wizard: uniform multi-step flow for all hosts; HOST2 pull moved
to checklist; auto SSH keygen and API key creation on save
- api/checklist.php: live setup checklist with pull_master action
- Fullscreen toggle: hide Unraid header/menu; state persists via localStorage
Skip list belongs to docker_watchdog, not stability_watchdog (legacy
naming from when docker+system were the only two watchdogs). Rename
variable and physical file system_watchdog_failed.db →
docker_watchdog_failed.db across all files.

Two-gate design: server must have ≥30 days uptime AND last run must
be ≥30 days ago. Both gates must pass before any scripts fire. Called
daily at 3am via cron — script self-gates, calling more often is safe.
State file on /boot/config (survives reboots): the interval gate is
independent of uptime. A reboot resets uptime but does not reset when
maintenance last ran — both gates must independently pass.
MONTHLY_MAINTENANCE_SCRIPTS added to master.conf in ORCHESTRATORS
section. zfs_pool_scrub.sh and smart_long_test.sh listed but commented
(neither script exists yet). Also commits mesh_monitor.sh move to
Monitors/ that was staged from prior session.
Supports --force to bypass both gates for manual runs.
Watchdog renames and moves:
system_watchdog.sh → stability_watchdog.sh (last line of defense — reboots)
storage_watchdog.sh → Watchdogs/System/storage_watchdog.sh
webgui_restart.sh → Watchdogs/System/webgui_watchdog.sh (renamed to match folder convention)
New thin orchestrator:
Watchdogs/system_watchdog.sh — runs SYSTEM_WATCHDOG_SCRIPTS from master.conf
Sits between docker_watchdog and stability_watchdog in the orchestrator tier chain
System/ subfolder is the growth seam for future system component watchdogs
master.conf:
WATCHDOG_ORCHESTRATOR_SCRIPTS updated — storage removed, system_watchdog added as tier
SYSTEM_WATCHDOG_SCRIPTS array added — storage + webgui
server_reboot.sh:
Calls array_stopping.sh before VM shutdown for guaranteed safe array stop
Removed raw rc.docker stop and exit trap — orchestrator owns container shutdown
- downloaders_reset: connection check block before slskd API sections;
triggers PUT /api/v0/server reconnect if disconnected, polls 60s,
gates Stuck Searches and Dead Transfer Records on SLSKD_CONNECTED
- Sync all modified/new/deleted files from v2 refactor across Docker_Essentials,
Media, Monitors, Partnership, Rsync, Tools, Transcodes, unRAID_Essentials,
common.sh, master confs, and new Manual/README docs
Introduce a four-layer self-healing stack replacing the continuous-loop watchdogs:
- resource_manager.sh (new): single-pass pressure reduction layer; throttles
SABnzbd/qBit at level 1, docker-pauses background containers at level 2,
docker-stops optional containers and signals docker_watchdog to defer at
level 3; graduated recovery with hysteresis
- watchdog_orchestrator.sh (new, Orchestrators/): runs resource_manager →
docker_watchdog → system_watchdog in sequence; intended for per-minute cron
via User Scripts; startup grace, acquire_lock to prevent pile-up, heartbeat
- docker_watchdog.sh: de-looped to single-pass; daemon strikes persisted to
state file across runs; cross-script coordination reads RM_STATE_FILE instead
of SYS_WATCHDOG_STATE_FILE
- system_watchdog.sh: de-looped to single-pass; stripped of all container
management (shutdown_non_essential_containers removed); reboot-only last resort
- master.conf: removed system_watchdog and docker_watchdog from
ARRAY_START_SCRIPTS; added WATCHDOG ORCHESTRATOR and RESOURCE MANAGER sections
- master_host1.conf: added RM_PAUSE_CONTAINERS and RM_STOP_CONTAINERS arrays
- common.sh: aliased RM_PAUSE_CONTAINERS and RM_STOP_CONTAINERS via detect_hosts()
- continuous_scripts_status.sh: moved to Tools/ (preserved for future use)
- sunday_morning_coffee_report.sh: watchdog section updated to use state file
mtime checks instead of is_running; added Resource Manager subsection;
fixed mem_shutdown grep filter pointing to wrong state file

- Rename array_start.sh → array_started.sh, array_stop.sh → array_stopping.sh
to clarify these are event-driven (array has started/is stopping), not imperative
- Update all references across 9 files (master.conf, user_script_plug-in.sh,
watchdogs, continuous_scripts_status.sh, claude_startup.sh)
- Add --remainder mode to docker_update.sh: updates all running containers
excluding daily containers, weekly sync-window containers (emby + critical-data),
and fallback coverage containers (FALLBACK_${MY_ID}_COVERS_${REMOTE_ID}_TIER*)
Fallback containers excluded because the remote server owns their version —
independent updates risk writeback incompatibility on handback
- weekly_sync_maintenance.sh calls docker_update.sh --remainder as final step
- git_pull_execute.sh: add safe.directory config to fix dubious ownership error
when running as root on a directory owned by uid 1000

common.sh:
- Add resolve_tailscale_ip() helper — tries `tailscale ip -4` first, falls back to
parsing `tailscale status` output; handles hosts where MagicDNS short-name resolution
is not active
- Add PARTNERSHIP_OWN_CONTAINERS alias in detect_hosts()
- Add aliasing for 4 Emby provisioning vars (PARTNERSHIP_PROVISION_EMBY_ADMIN,
PARTNERSHIP_EMBY_ADMIN_USER, PARTNERSHIP_EMBY_ADMIN_PASS, PARTNERSHIP_EMBY_PORT)
Partnership/partnership_manager.sh:
- Replace 9 bare `tailscale ip -4` calls with resolve_tailscale_ip()
- Add read_remote_conf_var() and read_remote_conf_array() — SSH to mirror, source its
own load_config.sh + detect_hosts(), return aliased variable; solves sparse-checkout
problem where HOST1 cannot read master_host2.conf directly
- Add derive_short_name() — strips unraid- prefix, capitalises first char
- Add cleanup_partner_containers() — removes partner containers via FolderView3 folder
if enabled, else falls back to FALLBACK_*_COVERS_*_TIER* arrays
- Add cleanup_owner_containers_on_mirror() — SSH to mirror, stops and removes containers
matching *-${OWNER_SHORT} naming convention
- Add start_own_stack() and start_mirror_own_stack() — restart own containers locally
or on mirror via SSH using PARTNERSHIP_OWN_CONTAINERS
- Add provision_emby_admin() — reads mirror credentials via read_remote_conf_var, checks
for username collision, creates user + sets password + grants admin policy via Emby API
- Add revoke_emby_admin() — looks up mirror username on local Emby, deletes via REST API
- Wire offboard paths (both mirror-initiated and owner-initiated) to call container
cleanup and stack restart; update --check finalisation paths accordingly
- Fix write_state_file in --onboard not gated on DRY_RUN (was writing ACTIVE state on
dry runs)
master_host1.conf:
- Add HOST1_PARTNERSHIP_OWN_CONTAINERS array
- Add partnership Emby provisioning config (toggle + port + per-host credentials)
master_host2.conf:
- Add HOST2_PARTNERSHIP_OWN_CONTAINERS array
- Add HOST2_PARTNERSHIP_EMBY_ADMIN_USER and HOST2_PARTNERSHIP_EMBY_ADMIN_PASS
Tailscale fix applied to:
- Initial_run/ssh_setup.sh (2 callsites)
- unRAID_Essentials/rsync_stop.sh (1 callsite)
