A Datab Node is the institution's own computer. It boots its own operating system, runs its own database, serves its own clients on the local network, and survives the internet going down. When the internet is up, the node syncs to other nodes and to head-quarters services. When the internet is down, work continues.

What ships on the node

• Current Ubuntu 24.04 Node image with systemd-supervised Datab services; Ubuntu Core/snap remains the target appliance distribution path.
• PostgreSQL 16 + Flyway-managed schema.
• Micronaut backend serving Datab Microfinance and Datab Cooperative workflows on the institutional network.
• Atlas Core for identity verification, trust, consent, and audit-linked records.
• Optional, pluggable local model runtime used by Orula when enabled.
• Orula and Gu agents (preview) for bounded intelligence and security.

What does not ship on the node

• No internet-only services. Every required workflow has an offline path.
• No vendor lock-in. The data is the institution's; export is built in.
