When One Gate's 'Open' Is Another Gate's 'Closed': Fixing Sync Drift
You see it on the dashboard: Gate A says open. Gate B, 300 meters away, says closed. Both are wired to the same logical barrier. The discrepancy sits there, logged at 14:23:17. No one caught it until a truck rolled through what Gate B thought was a locked barrier. This is sync creep. It is not rare. It is not trivial. And fixing it starts with one uncomfortable question: which gate do you trust? This article is for the person who has to answer that question before the next incident. We will walk through the options without vendor fluff, the criteria that actually matter, the trade-offs that keep you up at night, and the implementation steps that survive Monday morning. No guarantees. Just a framework. Who Decides? And By When? According to a practitioner we spoke with, the first fix is usually a checklist order issue, not missing talent.
