Production-grade Ruby client for Parse Server. Map Parse classes to Ruby models with typed properties, associations, and validations; build queries with a chainable DataMapper-style DSL; handle auth, sessions, MFA, cloud code webhooks, and push; introspect and migrate schemas; manage role hierarchies; scope access with per-agent ACL/CLP; generate GraphQL types; run Atlas Search and vector search; and bypass REST for high-throughput reads via the MongoDB-direct pipeline.
