  1. Decision Regression Harness — smallest dependency surface and immediately useful to anyone evaluating Jev.
  2. MCP Capability Router — a visually clear agent-infrastructure demonstration with measurable token and tool-selection outcomes.
  3. Agent Tool Firewall — a strong macOS/open-source demo, provided deterministic policy remains the final safety boundary.
