Debugged gate assignment

gate assignment{ A defined $K_5$ tree kernel is not a missing distribution. The missing object is its uniform internal amplitude description for the later joint composition.

It would be incorrect to mark H2 Constructed solely from that kernel's existence and then report the same amplitude gap as an H3 failure.

The legal ending is Unresolved at H2. The narrower single-Lagrangian identification is excluded, but the full class of allowed representations is not.}
