ok 1 - normalized nonnegative footprints for all pads and conservative stability bound
ok 2 - masked circular-basin MAC gradient and divergence obey summation by parts
ok 3 - N-body potential gradient agrees with finite-difference virtual work
ok 4 - 10,000-step closed undamped 7-pad run preserves volume and modified energy
ok 5 - pad-to-pad transfer is reciprocal (i->j equals j->i)
ok 6 - one-way control has no water->pad transfer; reciprocal has
ok 7 - uniform displacement is stationary; coupling-off is inert
ok 8 - the same invariants reject pressure sign, body sign, missing feedback and old-velocity drift
ok 9 - damped 7-pad release remains finite and loses most energy
# pass 9
