Open-Nucleus/server

Open-source, offline-first electronic health record (EHR) system for military forward operating bases, disaster relief zones, and small clinics in sub-Saharan Africa. # Open Nucleus Open-source, offline-first electronic health record (EHR) system for military forward operating bases, disaster relief zones, and small clinics in sub-Saharan Africa. Assumes zero connectivity as the default and treats network access as a bonus. **Architecture:** `ARCHITECTURE.md` | **Security:** `SECURITY.md` | **Privacy:** `PRIVACY.md` | **Internals:** `agents.md` ## Quick Start ```bash # 1. Start the IOTA Identity Bridge cd ../open-anchor/identity-bridge && npm install && node index.js # 2. Seed demo data (6 patients, cholera outbreak scenario) go run ./cmd/seed # 3. Start the server (port 8080) NUCLEUS_BOOTSTRAP_SECRET=demo go run ./cmd/nucleus # 4. Start the desktop app (in a separate terminal) cd open-nucleus-app && pnpm install && pnpm tauri dev ``` Login with practitioner ID `demo-clinician` (or any ID — the app auto-registers new devices via bootstrap secret). ### Build from source ```bash # Build server binary go build -o nucleus ./cmd/nucleus # Run with config NUCLEUS_BOOTSTRAP_SECRET=demo ./nucleus --config config.yaml # Build desktop app (macOS .app / Windows .msi) cd open-nucleus-app && pnpm tauri build ``` ### Minimal config.yaml ```yaml data: repo_path: data/repo # Git repository (source of truth) db_path: data/nucleus.db # SQLite search index (rebuildable) encryption: enabled: false # set true + provide master key for production tls: mode: "off" # "auto" for self-signed, "provided" for your own anchor: backend: iota network: testnet rpc_url: "api.testnet.iota.cafe" anchor_package_id: "0x..." # deployed Move contract identity_bridge_url: "localhost" ``` ## Ecosystem Open Nucleus is a 5-repo ecosystem: | Repo | Language | Purpose | |------|----------|---------| | **server** (this repo) | Go | Core EHR monolith — all services in-process | | **open-anchor** | Go + Node.js | IOTA Move anchoring, IOTA Identity SDK (DIDs, VCs, notarisation) | | **open-sentinel** | Python | LLM-powered sleeper a …
