What the process sees
What's actually true
Opacity is symmetric. The doomed path is dead but cannot tell — that is the lost-route window, the classic walking-dead interval in the technical lineage. The surviving path is alive but cannot tell — that is the surviving corridor. Same instance, same local view, opposite truths. Forfeiture measures how much available future commitment has already spent.
