CDP signal with Linux platform mismatch

Quick Analysis

• hasCDP is true, indicating that the browser exposes side effects commonly associated with Chrome DevTools Protocol automation.
• The user agent claims a Windows environment (Windows NT 10.0; Win64; x64), while runtime platform signals point to Linux x86_64.
• The WebGL renderer (ANGLE (Mesa/X.org, llvmpipe ...)) is also Linux-linked, which reinforces the mismatch between the claimed user agent and the actual runtime environment.
• The WebGPU fields remain in an uninitialized state (INIT), which suggests a non-standard runtime environment such as a server VM, container, or heavily instrumented browser session.
• pluginCount is 0, which is unusual for a normal desktop Chrome profile and adds another evidence of automation.
