The airflow is not attached, and the lift is Bernoulli caused. Others will find nits and pick them, but this is simple and succinct
Picking nits is what we do here. My best shot:

What causes wing lift in free flight is controversial. This may or may not apply to half-bodies that leak air through the connection to the ground plane.

However, this does not explain how asymmetric airfoils with pronounced positive camber at zero angle of attack, as shown in the figure below, create lift. In fact, such profiles were successfully used on early aircraft due to their resemblance to bird wings.

Incorrect Lift Theory
https://www.grc.nasa.gov/WWW/k-12/airplane/wrong1.html
The lift predicted by the "Equal Transit" theory is much less than the observed lift, because the velocity is too low. The actual velocity over the top of an airfoil is much faster than that predicted by the "Longer Path" theory and particles moving over the top arrive at the trailing edge before particles moving under the airfoil.
