Felt state PAD, -100 to +100
Bars show what it feels. The tall tick is its baseline; the small triangle is how much actually shows (expression).
Fire an event
Each button is one of this persona's declared triggers.
Delivery right now from the live mood
How the current mood colors expression, relative to this persona's resting delivery. This is what feeds the voice and behavior output, and it relaxes to nothing as the mood recovers.
This is the reference runtime for the spec's affect block: a baseline mood, reactivity (how hard events hit), recovery (how fast it returns), and expression (how much shows). The delivery nudges are the runtime's modulation layer, scaled by expression, so a guarded persona feels a lot and shows little. In an embodied agent this loop runs continuously, so the robot's tone tracks what just happened to it.
