The measure

Entropy gap is the Index’s language for dissonance: structural stress building in a system versus what is already priced, narrated, or felt on the surface.

Load alone can rise quietly. Narratives can stay calm. Spreads can stay tight. Gap is where those paths diverge.

Why it matters on the desk

Many risk tools measure market fear (VIX), credit opinion (ratings), or event narrative (geo briefs). Useful — often late.

Gap asks a different question: is the adaptive system carrying more disorder than the surface admits?

When gap reaches Crisis fashion on its own, that is a Watch alert under product doctrine — surface it. It is not, by itself, Act. Act requires dual Crisis: load and gap together.

Honest limits

Gap is not a crystal ball. It does not name the headline that will clear the dissonance. It measures conditions underneath.

We do not claim every Watch via gap becomes an Act dual, or that every Act dual maps to a named market event on a fixed lag. The sealed case studies show where the clocks lit relative to known breaks — including episodes where the macro stack does not fire. Honesty is part of the instrument.

How to read it with load

Read load and gap as a pair. Load without gap can mean stress the surface already knows. Gap without load can mean dissonance without full thermodynamic Crisis on the load face. Dual is when both clocks agree the system is in Crisis fashion — that is Act.
