The towel grasp with one and with two self-contact detections per substep

Recorded 2026-11-05 on ankac/alm-dat-main at 59bdf62d0 (today's main, the #4222 storage, ALM-DAT with decision D3). Same recipes as the campaign, 1280x720 per panel, 30 frames per second. The metric floor of that revision was still in place; the final metric rule (D15) came after these runs.

With two detections per substep, the host's default now also for alm_dat, both towels are held to the release like under VBD. With the single forced detection they are lost at the lift, at 5.50 s and 6.47 s, the same instants as in the campaign. Nothing else differs between the two ALM-DAT columns.
