Spectral Ruleset

# microsoft-azure-active-directory — 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: 2/2 servers on microsoft.com
#   - path-params-casing: kebab @ 75% (n=16)
#   - operationid-casing: camel @ 100% (n=24)
#   - schema-names-casing: pascal @ 100% (n=27)
#   - schema-properties-casing: camel @ 74% (n=246)
#   - security: global (root) — NOT emitting operation-security-required
#   - error-schema-defined: ODataError
#   - operation-documents-401: 100% adherence
#   - operation-documents-403: 100% adherence
