IAGA — Iris Affective Gamut Atlas

“Fear” is not only one word. The same fear may come from loss, threat, humiliation, or uncertainty, and it may coexist with anger, grief, anticipation, or longing. IAGA preserves the background that produced an emotion separately from the affective state that resulted, so systems can compare how the experience changes instead of reducing it to one label or a simple positive / negative score.

System boundary: IAGA describes and preserves the affective target. If a system tries to reconstruct that feeling in a particular person or substrate, Elysium must separately check personal differences, current state, permissions, and safety.

Story link: IAGA is not tied to one story chapter here. For a story-based way to understand mixed affect, read Causal Stack Overflow and the Dirty Golden Age. This is a reading example, not a claim that the chapter directly uses the name IAGA.
