The release claims a \"Flash and sandbox\" configuration beats Argon 100% versus 50% on ARC-AGI-2, and its `cerberus-mcp init` command provisions MCP server registrations and stop hooks for Claude Code, Cursor, Gemini CLI and VS Code Agent Mode while starting a 7-day `bundle:all_access` trial. Paid tiers are sold as annual Stripe subscriptions activated through signed offline `CERB1.` license tokens, with the free community tier limited to read-only AST manifold audits of `.py` and `.js`
