# statsd — AsyncAPI Spectral ruleset (strengthened)
# Plain Spectral. Rules measured from this provider's own AsyncAPI event
# conventions by strengthen_asyncapi.py, then self-validated against the spec.
#
# Provenance:
#   - channel-key-casing: camel @ 100% (n=4)
#   - message-name-casing: pascal @ 100% (n=15)
#   - operation-id-casing: camel @ 100% (n=4, v3)
#   - message-contenttype-defined: 100% adherence
#   - message-payload-defined: 100% adherence
