# snowflake — Spectral ruleset (strengthened)
# Plain Spectral. Existing hand-authored rules preserved; measured rules added
# from this provider's own OpenAPI conventions by strengthen_ruleset.py,
# then self-validated against the spec.

# Provenance:
#   - servers-https-only: 100% of servers already https (error)
#   - servers-expected-domain: 35/35 servers on snowflakecomputing.com
#   - path-params-casing: snake @ 91% (n=517)
#   - query-params-casing: camel @ 58% (n=81)
#   - operationid-casing: camel @ 98% (n=263)
#   - schema-names-casing: pascal @ 100% (n=249)

#   - security: global (root) — NOT emitting operation-security-required
#   - error-schema-defined: ErrorResponse
#   - operation-documents-400: 100% adherence
