Publication integrity record

Porous face vacuum gripper, per zone isolation, pump fed, contact triggered, vented before set down

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-2026-000006333) never changes.
