Publication integrity record

Porous face vacuum gripper, three zone face, ejector fed, contact triggered, 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-2026-000007354) never changes.
