Function encode_for_transport

atomic-canonical/src/delegation.rs:292–295

Encode a certificate for transport: JCS-canonical bytes, base64url, no pad. Canonical rather than "whatever bytes we happened to store" so the encoding is deterministic — which is what lets a server cache a verified certificate by content hash and recognise the same one next request.

    let canonical = jcs::canonicalize(document);
