DMN — Incident Priority Matrix (PRIORITY)

The classic impact-by-urgency matrix, written as a DMN table with an explicit PRIORITY hit policy so the output order decides which of several matching rules wins. Complete over both enumerated columns, so every incident that can be described gets a priority.
