Edit the JavaScript, run it through the configured demo gateway, and inspect the bounded receipt. The first lane receives a checked synthetic workforce/payroll-shaped fixture. The boundary lane has no host API grant and should not receive ambient filesystem, environment, or network access.

Demo gateway connection is not checked until you run a lane. This page uses the same origin by default; add ?api=https://gateway.example when the gateway is hosted separately.

The browser cannot choose the provider, isolation floor, grant profile, upstream URL, or credential. Those remain gateway-side configuration.
