# Prometheus config for the shithub monitoring host. All scrape
# targets are reached over the WireGuard mesh (10.50.0.0/24) — never
# the public interface.
#
# Cardinality budget: per the S36 perf pass, we keep label cardinality
# bounded by NOT labelling on user_id, repo_id, or path. Route metrics
# bucket by route name (set by the chi router); HTTP status is a
# small enum.
