Publication integrity record
System and method for achieving position detection integrity in an independent cart system
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-2026-000000122) never changes.
