The actual one-tree physical marginal before the equality limit

One physical cell is retained as its doubled Boolean pair. Every other physical cell, including small capacities zero and one, is summed at balance. The resulting positive scalar sequence has the proved raw log-concavity and finite interpolation bounds.

    Every retained tree mass is the finite equality-softening limit of its actual positive physical balanced sum.
