Principlev1
Include temporal trend information alongside point-in-time
Include temporal trend information alongside point-in-time status, because current state on a declining trend is more alarming than degraded state on a recovery trend.
Why This Is a Principle
Grounded in patterns existing hierarchically across scales (Patterns Exist in Hierarchical Logical Levels) and experience being segmented into events (Experience Segments into Nested Hierarchical Events). The principle prescribes showing trajectory to reveal higher-order patterns invisible in snapshots.
