# apache-dubbo — 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:
#   - path-params-casing: snake @ 100% (n=81)
#   - query-params-casing: snake @ 93% (n=56)
#   - operation-documents-500: 98% adherence
#   - pagination params observed: ['limit', 'offset', 'page', 'size']
#   - merge: kept 15 existing, added 2 measured, upgraded 0
#   - added: query-params-casing, operation-documents-500
