# lavu — 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 poslavu.com
#   - schema-names-casing: pascal @ 100% (n=11)
#   - schema-properties-casing: snake @ 100% (n=224)
#   - operation-security-required: 2/2 ops declare per-op security
#   - merge: kept 31 existing, added 4 measured, upgraded 0
#   - added: servers-expected-domain, schema-names-casing, schema-properties-casing, no-empty-descriptions
