ephemora-cell vs pic-standard

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.; pic-standard: PIC Standard is a lightweight, local-first protocol that forces AI agents to prove every important action before it happens, verifying intent, impact, provenance, and evidence. It acts as an action-bound verification contract that fails closed if any aspect of a high-impact tool call is found to be wrong or unjustified.
