# paystack — 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:
#   - server-secure-protocol: 100% of servers already secure
#   - message-name-casing: pascal @ 100% (n=24)
#   - message-contenttype-defined: 100% adherence
#   - message-payload-defined: 100% adherence
