"""Bot-detection challenges are handed to the user, never attempted.

Eric screenshotted the case on 2026-08-04: TikTok showing "Play the audio and enter the code you
hear" over a logged-out feed, while the run underneath burned its budget clicking at a page it could
never get past. These come in several shapes (audio, press-and-hold, slider/puzzle, image grid) and
they share one property: an agent cannot honestly clear any of them. It cannot hear the clip, and a
press-and-hold against a behavioural detector is a coin flip that reports success either way, which
is precisely the false-success class the rest of this suite exists to prevent.

So the rule is refuse and escalate. What these tests protect is (a) that the common shapes are
detected at all, and (b) that ordinary pages are NOT, because a detector that cries captcha on a
checkout form interrupts the user for nothing.
