Report #5215

[tooling] ChromeDriver detected and blocked by Cloudflare/DataDome despite using headless Chrome

Use undetected-chromedriver as a drop-in replacement for selenium.webdriver.Chrome. It auto-patches the ChromeDriver binary, removes the cdc\_ async script leak, fixes --headless=new artifacts, and handles navigator.webdriver. Replace webdriver.Chrome\(options=options\) with uc.Chrome\(options=options\) after import undetected\_chromedriver as uc.

Journey Context:
Manual stealth patches \(removing navigator.webdriver, patching cdc\_ async script\) break with every Chrome release and require constant maintenance. uc consolidates community patches into one maintained package. It is not magic—aggressive bot management still wins—but it eliminates the trivial headless-Chrome signature that triggers basic blocks. Alternative: selenium-stealth is lighter but covers fewer leaks.
