Verify a receipt

Check that a sealed advice is byte-for-byte what was published — without having to trust us.

Runs against the published roots. Nothing is sent anywhere.

What you’re checking

When an advice is sealed it gets a leaf hash, and that leaf is folded into the Merkle root for the day. Your receipt carries the leaf and the path to the root. If the advice were altered later, its leaf would change, and the recomputed root would no longer match the one already published on the transparency log.

That is what makes the guarantee independent of us. We publish the roots; you recompute them.

Demo behaviour. This currently matches against the seed corpus rather than recomputing a Merkle path. Real proof verification lands with the sealing pipeline.
