# amazon-app-studio — 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: 1/1 servers on amazonaws.com
#   - schema-names-casing: pascal @ 100% (n=3)
#   - schema-properties-casing: camel @ 50% (n=12)
#   - security: global (root) — NOT emitting operation-security-required
#   - pagination params observed: ['maxResults', 'nextToken']
#   - merge: kept 3 existing, added 6 measured, upgraded 0
#   - added: servers-https-only, servers-expected-domain, schema-names-casing, schema-properties-casing, security-schemes-defined, no-empty-descriptions
