puppeteer.launch spawns a browser process whose lifetime is not tied to the Node process in every failure mode. If the script throws between launch and browser.close, or is killed with SIGKILL, the Chrome process and its renderers survive, and a CI runner repeating this leaks memory until the job is evicted. An unhandled promise rejection that ends the script early does the same.
Wrap the run in try/finally with await browser.close() in the finally, and register SIGINT and SIGTERM handlers that close the browser before exiting. When you attach to an existing browser with puppeteer.connect, use browser.disconnect() instead, because close() there terminates a browser you did not start. Looking for stray Chrome and crashpad handler processes after a suite is the quickest way to confirm the leak exists.
