Planisphere measures your tool deployment against Extensive Form 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.
Extensive Form 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.
