Have you tried this on an actual board position? The first case has the eye graph "...!" but in the second case the topological half/false eye analysis should detect both a false eyepoint and a halfeye on the edge, and the eyespace segmentation should find ".h!" which is translated to a graph matching eye pattern 448 for a 0011 value.
Surely I have tried this position before I sent last mail, I attach the SGF here then for you reference. If I had not missed something, the topological code may not work well to detect the false & halfeye.
