# alpaca-markets — 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
#   - server-security-defined: 2/2 servers
#   - security-schemes: ['apiKeyAuth']
#   - message-name-casing: pascal @ 100% (n=11)
#   - payload-property-casing: snake @ 75% (n=59)
#   - operation-id-casing: camel @ 100% (n=4, v2)
#   - message-contenttype-defined: 100% adherence
#   - message-payload-defined: 100% adherence
