What does "open core" mean for Joyus AI?

The platform core — the MCP (Model Context Protocol) services, session and context state, workflow enforcement, and the specs that govern them — is public under the Apache License 2.0 at github.com/zivtech/joyus-ai. The organization-specific skills, customers’ private content, Joyus Enrichment, the Profile Engine, and ops are proprietary. Open core means the foundation is forkable and inspectable; the commercial layer that runs on top is not. The repo says exactly where that line falls.
