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
- puppeteer.launch is a function that returns a Promise
- puppeteer.launch rejects with Error when called without executablePath or channel in puppeteer-core
- puppeteer.launch rejects with Error when configured executablePath does not exist
- puppeteer.launch rejects with Error when channel executable is not found
- puppeteer.defaultArgs returns standard Chromium arguments with headless=new by default
- puppeteer.defaultArgs omits headless flag when headless is false and sets --headless when headless is shell
- puppeteer.defaultArgs adds --auto-open-devtools-for-tabs when devtools is true
- puppeteer.defaultArgs appends custom command line flags and sets user-data-dir option
