Introducing Trusted Remote Execution — an open source scripting runtime built on a simple rule: no operation executes without explicit policy authorization.
• Rhai scripts: sandboxed, no built-in host access
• Cedar policies: declarative rules for what's allowed
• Same enforcement for human-triggered and AI-triggered scripts
