Publication integrity record

Porous face vacuum gripper, per zone isolation, pump fed, vented after set down, open 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-2026-000007088) never changes.
