Phalaenopsis Yellow Leaves, Rotting Roots: Emergency Sphag-and-Bag

Phalaenopsis: 3 large leaves, split spike, 1 flower. Bottom leaf yellow, spreading up. SE window, filtered. Roots rotting—trimmed to 1" live root. Repotted bark/charcoal, withheld water 1 week, no change. Lost cause?

Root Loss = Leaf Loss

Limp, wrinkled leaves = roots can't supply water. Repot good but may not save with so few roots.
