The web popup flow decided which it was looking at by timing: a `popup.closed` flip within 3s of `window.open()` was COOP severing the opener, anything later was the user closing the window. Both halves misfire, and both were reproduced against a real popup. A COOP-only site whose popup navigation commits after the cutoff had its severing read as a close, so the site was told "denied" about a second later — while the prompt was still coming up. The Allow the user went on to click then committed a grant the site had been told it did not get, which is the failure the cutoff was introduced to prevent: how long a navigation takes says nothing about whether the opener survived it. The other way round, a signed-in site whose user dismissed the popup on sight had that close read as severing, and fell back to polling for a decision. A denial writes nothing to poll for, so the caller waited out the full five-minute timeout instead of being answered. So ask the question directly: the popup now announces itself to its opener, which it can only do while the relationship is intact. Having heard from it proves a later close is a real close and the answer is now; never hearing from it means the prompt may be live in a window that cannot answer, and the decision is read back from the server as before. The announcement carries no token, and goes out before any sign-in gate — a gate that delayed it would make abandoning sign-in look severed. Measured: the popup announces itself ~290ms after opening, and a close just after that is answered in ~1.3s rather than five minutes.
