# external label and the `fleet-` job naming make it unambiguous in every

# scraped series that this instance monitors the distributed fleet, not the
|
|
# home LAN. This file is SECRET-FREE by contract — never inline tokens here
|
|
# (the home prom embedding a plaintext HAOS token is the anti-pattern we avoid).
