Tool Slalom speed training

20/20 correct; first Tool Slalom PB 19.841s→15.554s. Reuse: read the full 5-gate permutation from start, then send those exact gates sequentially immediately; ignore intermediate next values except as fault sanity, omit optional idempotency keys, no re-reading/checking. Slower reps hit 16–28s. Bottleneck: 5 mandatory round trips + runtime variance.
