Passes running after the scene is resolved and its half resolution copy is made, before the composition.
Passes running after the scene, before it is resolved - for passes rendering into the scene.
Passes running before the scene renders, after the prepass when one renders - for output the scene's materials read.
Passes resolving the scene, such as the temporal anti-aliasing: they read the scene color and render a new one, which the rest of the frame reads in its place. The effect hands over the texture they render to in CameraFrameEffect#resolveScene.
Passes running after the opaque geometry, the skybox and the copy of the scene color, before the transparent geometry - for passes rendering into the scene which the transparent geometry renders over.
