Zero-Sum is a strategic-interaction primitive: the game shape Planisphere can detect inside an AI tool deployment's behaviour.
Answers: How does Planisphere recognise a Zero-Sum pattern in an AI tool deployment?
What this is.
Use. strict conflict · Σ = 0.
Source. opposed arrows + brass equality bars.
Register. 05 · Game theory — one of the ten registers of the PLANiSPHERE corpus library.

Planisphere measures your tool deployment against Zero-Sum and seals the result into a signed, Merkle-rooted evidence record. The grade recomputes on your own hardware; the model state never crosses the boundary.
The board that carries this.
Zero-Sum is measured into the same evidence record as every other mark in the Game theory register. That measurement becomes compliance-ready buyer evidence at /trust-packet.
