Around remaining blockers (Zapier login, live Verae): generate PDF receipts
without extra deps; AES-256-GCM object store with tenant isolation and share
tokens; scripts/nats-tunnel.sh to NS1; SHA256 Hash Text local Zapier action;
scripts/test-offline.sh for the no-login suite.
Learned: other-tenant object GET is 403; share token is the mock unwrap path.
GET /zapier/v1/receipts/{jobId}?format=json returns a retrieval receipt
with extraSeal.event=document.retrieved. PDF format is 501 until legal
copy exists. OPEN.md lists work that needs Zapier login or live Verae.
