ZION-8 — Approvals Nick can read cold, and the business workspace Approvals line

ZION-8 is replanned around acknowledgements written by the exact receiving session. Step 1 is the sole startable step and creates every later proof mode before use. No product step is marked complete. Open work includes one hashed real Slack envelope, a visible Notification Center read, live process/socket ownership, the fixed receiver writer and same-boot clock, a real ZION-7 destination receipt, primary-evidence tier rows, separate security controls, and broadcast completion only after every intended recipient acknowledges. The eight unsupported historical relays remain the relevant item.
