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
- In puppeteer 24.2.1 compared to 24.2.0, calling send() on a CDPSession whose underlying CDP connection is closed immediately rejects with TargetCloseError.
- In puppeteer 24.2.1, network request interception CDP errors containing Unsafe header are re-thrown by handleError rather than swallowed.
