ephemora-cell vs centian

ephemora-cell: Ephemora Cell is an execution layer designed for running untrusted AI-generated code safely within a capability-based WASM environment. It provides strict resource limits and enforces security boundaries to protect the host system from potentially malicious or buggy code.; centian: Centian is a crucial layer sitting between AI agents and the systems they interact with, providing security, observability, and control. It captures every agent action, enforces allowed behaviors, and verifies execution against predefined contracts to mitigate risks in production environments.
