# 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 booking.com
#   - operationid-casing: camel @ 100% (n=39)
#   - security: global (root) — NOT emitting operation-security-required
