Server Inspection Reference
When asked to inspect a server without a URL, assume the local machine Hermes runs on.

Scope Signals
| User says | Means |
|---|---|
| "服务器巡检" / "server inspection" | Local machine (no URL given) |
| "巡检 ephron.ren" | Remote web service at that domain |
| "check the service on port 8000" | Likely remote host:port |
| "你的服务器" / "this machine" | Local machine explicitly |
Anti-Patterns
- Don't default to checking remote web services when no URL is provided
- Don't assume the remote service is on the same machine as Hermes
- Do ask for clarification if "server" could mean local or remote
