does five steps: hear, understand, check, route, and answer. The Hub does not
hold a personality or a memory. The Hub does not do the destination work.

## Core Configuration

- **Env File**: `~/.config/environment.d/10-secrets.conf`
- **Config Directory**: `docs/`
- **Active Ports**: Hub port not allocated yet.
