# amazon-mediatailor — 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)
#   - path-params-casing: pascal @ 100% (n=52)
#   - query-params-casing: pascal @ 52% (n=31)
#   - operationid-casing: pascal @ 100% (n=44)
#   - schema-names-casing: pascal @ 88% (n=174)
#   - schema-properties-casing: pascal @ 100% (n=422)
#   - security: global (root) — NOT emitting operation-security-required
#   - pagination params observed: ['maxResults', 'nextToken']
#   - merge: kept 20 existing, added 5 measured, upgraded 0
#   - added: path-params-casing, query-params-casing, schema-names-casing, schema-properties-casing, no-empty-descriptions
