This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- Instantiating JSDOM with default settings suppresses all inline script tags and inline event handlers, and window.eval throws a ReferenceError because no VM context is attached.
- Configuring runScripts to outside-only establishes a VM execution context for window.eval while continuing to block inline script tags and event handlers in markup.
- Configuring runScripts to dangerously executes inline script tags and event handler attributes within the JSDOM window context.
- Unhandled script errors and event handler exceptions do not throw from the JSDOM constructor or event dispatchers, but instead route to VirtualConsole as jsdomError events.
- VirtualConsole sendTo forwards console logging methods while supporting omitJSDOMErrors to filter out uncaught script exceptions.
