zygotectl build -hyperlight-snapshot snap/ -hyperlight-helper /usr/local/bin/hyperlight-helper -seal-to fleet-pub.json -out out/hl
zygotectl push  -dir out/ref -ref http://127.0.0.1:5000/zygotes/ref:v1

The digest build and push print is the grant's template_digest. The images a build takes are sealed to the fleet's public wrap key (fleet-pub.json, from grant-issuer keygen -alg A256GCM). The author holds nothing that opens them. Only homes, which hold the fleet's seal key, do.
