A hand-back used to restart the window, so a guard and a charge taking turns hid the loop's integrator bound for good (0 warnings in 2 h; 28 before the fix). A run of hand-backs (the wire away less than a settle between them) now hides the bound for at most 11 bound cycles and 22 s in all, then it counts. The quarter-edge kick stays hidden. No command or text changes. Tests for the two reviewer mutants that only unit checks caught (a restart counted as a hand-back; span only), DECISIONS gives the delay at 2 s, 5 s and 60 s. test_safety87.py:543 shortened.
