Publication integrity record

Single cup vacuum gripper, common isolation valve, pump fed, sustained blow-off after set-down, on a tool changer

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-2026-000040845) never changes.
