For performance reasons, AP only checks every entrance once. However, if entrance access conditions depend on regions, then it is possible for this to happen:
1. An entrance that depends on a region is checked and determined to be nontraversable because the region hasn't been reached yet during the graph search.
2. After that, the region is reached by the graph search. The entrance *would* now be determined to be traversable if it were rechecked.
2. After that, the region is reached by the graph search.
The entrance *would* now be determined to be traversable if it were rechecked, but it is not.
To account for this case, AP would have to recheck all entrances every time a new region is reached, until no new regions are reached.
However, there is a way to **manually** define that a *specific* entrance needs to be rechecked during region sweep if a *specific* region is reached during it. This is what an indirect condition is.
