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.

|
|
# PURPOSE
|
|
# ─────────────────────────────────────────────────────────────────────────────
|
|
# At-a-glance view of everyone in the mesh — who they are, how to reach them,
|
|
# and what services each node has put up for mutual fallback protection.
|
|
# Read-only — sources conf data only, no SSH or API calls, no sensitive data.
|
|
#
|
|
# ==============================================================================================
|
|
# OPERATIONAL MODEL
|
|
# ==============================================================================================
|
|
#
|
|
# Reads directly from all three conf files without detect_hosts().
|
|
# Iterates all defined HOST* vars — scales automatically as new nodes join.
|
|
#
|
|
# Sections:
|
|
# MEMBERS — server name, owner, contact email for each HOST*
|
|
# COVERAGE — what each host runs for others when they go down, by tier
|
|
# PARTNERSHIP — enabled/disabled, current owner, sync interval
|
|
#
|
|
# Safe to share with mesh members — contains no API keys, passwords, or SSH keys.
|
|
#
|
|
# ==============================================================================================
|
|
# CONFIGURATION
|
|
# ==============================================================================================
|
|
#
|
|
# host*.conf — per-host identity vars read by this script:
|
|
#
|
|
# HOST*_OWNER human-readable owner name
|
|
# HOST*_OWNER_EMAIL contact email — also used by NPM for Let's Encrypt
|
|
#
|
|
# ==============================================================================================
|
|
# RUNTIME MODES
|
|
# ==============================================================================================
|
|
#
|
|
# mesh_monitor.sh — show full mesh overview
|
|
# mesh_monitor.sh --log — verbose output
|
|
# mesh_monitor.sh --status — show config and exit
|
