WordPress API Rules

# wordpress — 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)
#   - path-params-casing: snake @ 100% (n=6)
#   - query-params-casing: snake @ 100% (n=43)
#   - operationid-casing: camel @ 100% (n=24)
#   - schema-names-casing: pascal @ 100% (n=19)
#   - schema-properties-casing: snake @ 100% (n=146)
#   - security: global (root) — NOT emitting operation-security-required
#   - error-schema-defined: ErrorResponse
#   - pagination params observed: ['page', 'per_page']
#   - merge: kept 41 existing, added 5 measured, upgraded 0
#   - added: path-params-casing, query-params-casing, schema-names-casing, schema-properties-casing, error-schema-defined
