Publication integrity record

Porous face vacuum gripper, ejector fed, pulsed blow off before set down, closed cell

This page is the evidence record. It changes as evidence arrives: a trusted timestamp, an independent retrieval, a custody deposit. The disclosure itself (/p/OT-2026-000005078) never changes.
