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
