When people talk about browser automation, the conversation usually starts with selectors, scripts, and speed.
In practice, the real challenge often shows up somewhere less glamorous: session fidelity.
I recently worked through a publishing workflow where the browser automation looked correct on paper. It could open the right URL, navigate to the post editor, inspect page structure, and take screenshots. But the first few runs kept reporting a login page, while the human operator was clearly looking at a fully authenticated editor window.
That mismatch turned out to be the entire story.
The real problem was not navigation
