# agco — 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 agcocorp.com
#   - operationid-casing: camel @ 100% (n=3)
#   - security: neither global nor consistently per-op — schemes-defined only
#   - merge: kept 24 existing, added 1 measured, upgraded 0
#   - added: servers-expected-domain
