Report #386

[tooling] Selenium ChromeDriver immediately blocked by Cloudflare, DataDome, or Imperva

Drop in undetected-chromedriver: import undetected\_chromedriver as uc; driver = uc.Chrome\(\). It patches the driver binary, launch flags, and automation variables automatically.

Journey Context:
Vanilla ChromeDriver advertises automation via --enable-automation, navigator.webdriver, and predictable WebDriver properties. undetected-chromedriver renames WebDriver variables, removes automation flags, randomizes the UA, and manages driver downloads. It is not an IP solution, so combine with a proxy for datacenter IP reputation. It also cannot patch CDP-level detection; if it fails, switch to a CDP-less approach like nodriver.
