# ================================= Array Start Orchestrator ===================================
# ==============================================================================================
#
# PURPOSE
# ─────────────────────────────────────────────────────────────────────────────
# Single entry point for array start — fired by the Varaverk plugin's
# disks_mounted event hook (Plugin/unraid/event/disks_mounted/array_start_jobs).
# Launches everything configured in ARRAY_START_SCRIPTS in master.conf.
# This script exits after launching all scripts — the event hook sees it complete normally.
#
# ==============================================================================================
# OPERATIONAL MODEL
# ==============================================================================================
#
# Configured in master.conf ARRAY_START_SCRIPTS — no changes to this script ever needed.
# Current order (order matters — see below):
#
# ONE-SHOT (run and exit naturally):
# System_Essentials/unraid_api_key_renew.sh — re-register Varaverk API key at boot
# System_Essentials/inotify_tuning.sh — raise inotify limits before containers start
# System_Essentials/docker_syslog_filter.sh — suppress veth log noise before logs fill
# System_Essentials/php_fpm_max_children.sh — WebGUI performance tuning
# Transcodes/ramdisk_setup.sh — create tmpfs + symlink before Emby starts
# Docker_Essentials/docker_network_connect.sh — ensure networks + container connections
#
# CONTINUOUS (run until array stops):
# Fallback/fallback.sh — mutual fallback monitor
#
# NOTE: watchdogs (docker, system, stability) are NOT launched here.
# They run via watchdog_orchestrator.sh every 15 min (cron), not as daemons.
#
# Script is launched in background with bash script.sh &
# After 1 second: if PID still alive → continuous (running in background)
# if PID dead + exit 0 → one-shot completed successfully
# if PID dead + exit N → failure
#
# ==============================================================================================
# DESIGN PRINCIPLES
# ==============================================================================================
#
# Order Is Load-Bearing
# inotify limits must be raised before containers start — containers that
# start with low limits keep them. Ramdisk must exist before Emby starts.
# Docker networks must be connected before watchdogs check container states.
# fallback.sh goes last — it needs everything else stable to make decisions.
#
# Configuration Owns the List
# ARRAY_START_SCRIPTS in master.conf is the only place scripts are added or
# removed. This orchestrator never needs to be edited to change what runs —
# one-shot vs continuous behaviour is auto-detected from the PID after launch.
#
# ==============================================================================================
# OPERATIONAL SAFEGUARDS
# ==============================================================================================
#
# Root check — all launched scripts require root
# acquire_lock — prevents duplicate array start launches
# detect_hosts() — MY_ID in notifications
# platform_require_cmd — notify validated before use
# chmod +x auto-fix — non-executable scripts fixed before launch
# Full path on failure — shows exact path for debugging
# notify on failures — alert if any script fails to launch
#
# ==============================================================================================
# CONFIGURATION
# ==============================================================================================
#
# master.conf
#
# ARRAY_START_SCRIPTS — ordered list of scripts to launch at array start
#
# ==============================================================================================
# RUNTIME MODES
# ==============================================================================================
#
# array_started.sh
# Normal launch — called by Varaverk disks_mounted event hook.
#
# array_started.sh --dry-run
# Show what would be launched without launching.
#
# array_started.sh --status
# Show configured scripts and their current state.
#
# array_started.sh --log
# Verbose output per script.
