Answers: What is SHA-256 digest in the Planisphere corpus library?

02 ·

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.

Source. wave of varying bars → arrow → 4 brass output bars.

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.

API ·

When a regulator asks for proof, hand over records — not assurances.

record the duty · seal the receipt · verify offline

Planisphere records each duty event — an output marked, a disclosure shown, a review made — and seals it into a receipt that verifies offline against our published keys. You send hashes, never content. A record is evidence a third party can check; it is not a certification and not a legal determination.
