Module 2’s serial-and-firmware table caught two devices we had never labeled after a firmware bump. That alone justified the Vault Codex seat for our household.

Daejeon · Jun — The dual-location map is tidy. The live sessions ran late for my timezone once, so I relied on recordings for the passphrase worksheet.
Client in boutique custody ops: we adapted the handoff checklist from Archive Atelier when an operator rotated out. Ink stayed consistent across three safes.

The restore rehearsal in the flagship course is useful, though I wanted more examples for multi-sig setups. Still clearer than our prior sticky-note system.

Case study: Coastal relocation notebook rewrite
A two-person household moved hardware from a city apartment to a Jeollanam-do storage site. Before the course they kept seed location hints in a shared chat. During Vault Codex they rebuilt device pages, assigned a sealed envelope index, and timed a dummy restore at 11 minutes. Their mild reservation: printing the large map pages required a local shop visit. Outcome they reported: fewer “where did we put…” conversations during the move week.

Case study: Shared drawer without shared confusion
Three collaborators used Archive Atelier to document which operator may open which drawer. They kept passphrase policy language deliberately vague on paper and stored fuller rules offline separately — a pattern taught in Module 3. They noted the curriculum assumes you already know your device manufacturer’s recovery screens; Nodeapi Hub does not replace those manuals.
