# apache-james — 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 @ 75% (n=8)
#   - operationid-casing: camel @ 100% (n=16)
#   - schema-names-casing: pascal @ 100% (n=9)
#   - schema-properties-casing: snake @ 64% (n=22)
#   - security: global (root) — NOT emitting operation-security-required
#   - merge: kept 20 existing, added 3 measured, upgraded 0
#   - added: operationid-casing, schema-names-casing, schema-properties-casing
