# apigee — JSON Schema Spectral ruleset (strengthened)
# Plain Spectral. Rules measured from this provider's own JSON Schema
# conventions by strengthen_jsonschema.py, then self-validated against them.
#
# Provenance:
#   - schema-declares-$schema: 110/110 roots
#   - schema-draft-consistency: 2020-12 @ 100%
#   - schema-has-title: 110/110 roots
#   - property-name-casing: camel @ 56% (n=732)
#   - def-name-casing: pascal @ 67% (n=12)
