Statement
For four invertible canonical routes with common source and target, put , , , and . Then .
Meaning and scope
The order of factors matters. The identity follows from cancellation of these specified finite routes; it does not establish analytic totalization. Trivial directional defects imply equality of the two surface comparisons, not that they equal the identity.
