Evidence pack composer

Build a fake evidence pack from a sample request, see canonical-JSON, compute SHA-256.

No private key in browser — signature shown is a placeholder, not real.
Inputs
Canonical JSON + hash
// click "Build pack"
Note on signing
In production, the canonical JSON is signed with an Ed25519 key (see Admin » Keys for KID rotation). We display the signature field as a placeholder so the shape is realistic; the bytes are not a real signature because no private key is available client-side. The hash is computed in your browser via SubtleCrypto and is real.
