Hypixel API Rules

# authorship: generated by API Evangelist tooling. Stamped 2026-08-18

x-method: generated
# hypixel — 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 hypixel.net
#   - query-params-casing: snake @ 100% (n=34)
#   - operationid-casing: camel @ 100% (n=68)
#   - schema-names-casing: pascal @ 100% (n=22)
#   - schema-properties-casing: snake @ 87% (n=138)
#   - security: global (root) — NOT emitting operation-security-required
#   - pagination params observed: ['page']
#   - merge: kept 36 existing, added 4 measured, upgraded 0
#   - added: query-params-casing, schema-names-casing, schema-properties-casing, no-empty-descriptions
