Publication integrity record

Porous face vacuum gripper, per zone isolation, ejector fed, pressure verified at each zone

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-2026-000003652) never changes.
