# acuity-brands — 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 acuitybrands.com
#   - path-params-casing: camel @ 100% (n=5)
#   - query-params-casing: snake @ 84% (n=19)
#   - operationid-casing: camel @ 100% (n=9)
#   - schema-names-casing: pascal @ 100% (n=10)
#   - schema-properties-casing: snake @ 55% (n=58)
#   - security: global (root) — NOT emitting operation-security-required
#   - operation-documents-401: 100% adherence
#   - pagination params observed: ['cursor', 'limit']
#   - merge: kept 23 existing, added 6 measured, upgraded 0
#   - added: servers-expected-domain, path-params-casing, query-params-casing, schema-names-casing, schema-properties-casing, no-empty-descriptions
