Spectral Ruleset

Raw ↑ 
# at-and-t — 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: 3/3 servers on att.com
#   - path-params-casing: snake @ 58% (n=12)
#   - query-params-casing: snake @ 67% (n=9)
#   - operationid-casing: camel @ 100% (n=26)
#   - schema-names-casing: pascal @ 100% (n=37)
#   - schema-properties-casing: snake @ 57% (n=91)
#   - security: neither global nor consistently per-op — schemes-defined only
#   - error-schema-defined: ErrorResponse
#   - operation-documents-401: 100% adherence
#   - pagination params observed: ['limit', 'offset']
#   - merge: kept 37 existing, added 7 measured, upgraded 0
#   - added: servers-expected-domain, path-params-casing, query-params-casing, schema-names-casing, schema-properties-casing, error-schema-defined, operation-documents-401
