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.

# PURPOSE
|
|
# ─────────────────────────────────────────────────────────────────────────────
|
|
# Runs at array start after conf_sync.sh. Checks whether partner confs made it
|
|
# into the RAM cache. If any are missing (partner was unreachable at boot) and
|
|
# a persistent backup exists from the previous shutdown, loads the missing confs
|
|
# from backup into the RAM cache so scripts like fallback.sh have partner vars.
|
|
#
|
|
# Always removes the persistent backup when done — used or not.
|
|
#
|
|
# Normal reboot (partner up):
|
|
# conf_sync.sh pulls fresh → RAM cache complete → backup not needed → removed
|
|
#
|
|
# Edge case (partner down at boot):
|
|
# conf_sync.sh fails to pull → RAM cache missing partner → backup loaded into
|
|
# RAM → backup removed → fallback.sh runs with last-known-good partner vars
|
|
#
|
|
# Own conf is never in the backup — it's always on disk.
|
|
#

|
# DESIGN PRINCIPLES
|
|
# ==============================================================================================
|
|
#
|
|
# Remove After Use
|
|
# The persistent backup is always removed at the end of the run — whether it
|
|
# was used or not. Stale backups from a previous shutdown should never be left
|
|
# behind as a permanent fallback; the backup is a single-boot safety net, not
|
|
# a long-lived cache.
|
|
#
|
|
# Partner Only
|
|
# Own conf is on disk and is always available regardless of array or partner
|
|
# state. Only partner confs can be missing after a boot — only those are
|
|
# restored.
|
|
#

# OPERATIONAL SAFEGUARDS
|
|
# ==============================================================================================
|
|
#
|
|
# require_partnership — exits early if PARTNERSHIP_ENABLED=false
|
|
# detect_hosts() — determines which conf files belong to partners vs self
|
|
# No-backup guard — exits cleanly if PERSISTENT_CONF_CACHE doesn't exist
