"""Tests for manual event severity categorization.

Regression coverage for manual events created via the events API being
categorized as detections when their label appears in both the alerts and
detections label lists. Alert labels must win, matching how tracked objects
are categorized, and labels in neither list must default to alerts so the
historical behavior of the API is preserved.
