What you're looking for is predecessor/successor/unrelated in the context
bert's history. Before/after is meaningless if they don't share a timeline.
(Much like relativistic events outside each other's light cone, and you can
never trust time stamps.)
Don't we have a less-than relation on tree-ordered history traces that does
exactly that?
