User provides URL list through sinbyte.com web app -> Extension receives URLs via window.postMessage -> For each URL, extension searches Google and parses results to determine if URL is indexed -> Extension also checks HTTP status codes and robots.txt -> Results sent back to web app via PUT request -> Results displayed in sinbyte.com dashboard

Reason: The extension has no login UI, no authentication logic, no API keys, and no token-based access control.

The extension's core functionality (checking Google index status) works without any account.
