What this is.

twelve marks · the evidence record's actual machinery · same construction · 200×200 · integer geometry · currentColor + brass-deep

Use. collapsing variable input to a fixed 64-char hash.

See it work.

Evidence record you can check — not code you have to trust.

Planisphere measures your tool deployment against SHA-256 digest 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.

Related marks, and the surface this one funnels to.

SHA-256 digest is measured into the same evidence record as every other mark in the Cryptography primitives register. That measurement becomes compliance-ready buyer evidence at /trust-packet.
