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
- page.evaluate executes JavaScript functions inside the page execution context and transfers serializable return values back to Node.
- Returning document DOM nodes directly from page.evaluate serializes as empty objects across the protocol, requiring property extraction or page.evaluateHandle for DOM references.
- Synchronous Node functions exposed to the browser via page.exposeFunction return Promises that resolve to their returned values when awaited in the page.
- The complete contract runs in the pinned Chrome 134 browser with container networking disabled.
