Right now the implementation of dot
imposes a 10 degree latitude-exclusion region near each pole, which serves two purposes: it avoids the coordinate singularity at the pole where the longitude becomes meaningless, and it limits us to be sensitive only to the spots that rotate into and out of view (true polar spots cause no rotational modulation). I haven't implemented faculae in any way yet, but that'd be a neat addition!
At least for the Sun, spot darkening and faculae brightening largely cancel at the limb, so I think it is reasonable to limit the latitudes when stars are nicely perpendicular like the one you showed.
