What the process sees
What's actually true
Opacity is symmetric. The doomed trajectory is dead but can't tell — that's W. The surviving trajectory is alive but can't tell — that's the corridor. Same opacity, opposite fates. G measures forfeiture — how much available room commitment has cost. Toggle between them: same formula, same local view, opposite truths.
