# Standalone verification of the API endpoint consistency implementation (issue #944).
# Run without loading Rails: ruby test/support/verify_api_endpoint_consistency.rb
# Or with bundle: bundle exec ruby test/support/verify_api_endpoint_consistency.rb
#
# Option: pass --compliance to also scan the current API codebase and report violations
# (rswag specs using OAuth instead of API key, missing Minitest for API controllers,
# rswag specs with expect/assert).
