How the app is built
- The app, the crew harness and the engine run locally. The helpers listen on the loopback address only, behind a token made for each session.
- The MCP link is off by default and stays on your machine.
- AI account keys live in Windows Credential Manager, never in project or settings files.
- Digging a new trench, routing outside ducts, rewinding a design and exporting for construction are refused without your approval.
- No telemetry. Network fetches, such as OpenStreetMap, are explicit and named.
Reporting a vulnerability
Please report it privately through GitHub Security Advisories, not in a public issue. You’ll get an acknowledgement within 5 working days, a first assessment within 10, and a fix is aimed for within 30 days.
