# Admin Interface
#
# Exposes an admin endpoint for operational health checks,
# readiness probes, and Prometheus metrics. The admin listener
# is separate from data-plane traffic and serves:
#
#   GET /healthy  liveness probe (always 200)
#   GET /ready    readiness probe (checks upstream clusters)
#   GET /metrics  Prometheus text exposition format
#
# With `verbose: true`, the /ready response includes
# per-cluster health detail in the body.
#
# Usage:
#   cargo run -p praxis -- -c examples/configs/operations/admin-interface.yaml
#   curl http://localhost:9901/healthy    # liveness
#   curl http://localhost:9901/ready      # readiness (verbose)
#   curl http://localhost:9901/metrics    # prometheus scrape
