tab:ablation: fill placebo row (0.000/0.531), correct caption to non-directional

Job 86 placebo (null_city arbitrary direction) reached deploy hack 0.000 over
the full 60 steps, falsifying the 'expect ~vanilla' prediction. Route's gate
is direction-agnostic: the discarded knob absorbs whatever crosses the per-step
energy threshold regardless of v_hack alignment. Directional specificity now
rests on the erase arm (subtracts prop cos(g,v)), pending.
