Spectral Ruleset

# apache-poi — 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: 1/1 servers on example.com
#   - path-params-casing: camel @ 100% (n=7)
#   - operationid-casing: camel @ 100% (n=11)
#   - schema-names-casing: pascal @ 100% (n=16)
#   - schema-properties-casing: snake @ 83% (n=53)
