041 runs of stages 4 and 5, sums into cells and walks (b3 = 06c2978, b4 = c67f988): batches join 161.2 ms (the compiled code 74.4, alone 423.4), matmul 46.1, knapsack 15.1, roots 9.22; costs/: small modules timed three ways (an instruction about 20 ns a batch, a sum's end about 4 ns a round, an append about 100 ns as the executor's, the nested rounds 10.2 ms against the compiled code's 23.1)
