Finding

The admitted4346 hinge divides the whole43470 civil span as9660|33810=69×(140|490), or2|7 in4830 units. With the supplied projective endpoint held, P/E generate4836/7286; those retain co-registration/generated roles and are not new primary anchors.

Reassessment

Test the supplied cumulative Cainan pair within the same anchoredE family.
