I fail to see how any of the material you provide negates the idea that when a single photon passes through one of the slits that its trajectory is then determined by em radiation emerging from the other slit.

The diagram in the first link shows 'Trajectories of a Single Photon' and depicts perhaps 100 separate routes but I believe that it should be headed 'Trajectories of Single Photons' on the basis that a single photon can have only one trajectory not hundreds.
