# amazon-managed-apache-flink — 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: 50% of servers already https (warn)
#   - operationid-casing: pascal @ 100% (n=31)
#   - schema-names-casing: pascal @ 100% (n=297)
#   - schema-properties-casing: pascal @ 100% (n=459)
#   - security: global (root) — NOT emitting operation-security-required
#   - merge: kept 18 existing, added 3 measured, upgraded 0
#   - added: operationid-casing, schema-names-casing, schema-properties-casing
