What the Mood answers
The Mood is how the story is being read: fear, greed, consensus, controversy, trust in leadership, memetic spread—everything in the social and mental layer around the facts.
It is deliberately not The Mechanics (raw motion by itself) and not The Map (what is formally allowed). The same flows can coexist with opposite moods; the pillar exists so you do not confuse price with truth or hype with permission.
