Executive Summary + +`nx9-wg` is a sovereign, self-hosted, Linux-native VPN and network control plane built directly around the Linux kernel's in-tree WireGuard implementation (`wireguard.ko`). + +Rather than functioning as a fragile user interface wrapper that shells out to external command-line utilities (`wg`, `ip`, `nft`, `sysctl`), `nx9-wg` establishes an integrated, single-binary architecture. It combines **authoritative SQLite desired-state persistence**, **direct kernel Netlink execution** (RTNETLINK and WireGuard Generic Netlink), **in-process Netfilter firewall/NAT compilation** (`libnftables.so.1`), **continuous closed-loop reconciliation**, a **multi-format native CLI**, and an **embedded zero-dependency Single Page Application (SPA) Web UI**. + +--- + +## 2. The NX9 Philosophy in Implementation + +Every design and architectural choice in `nx9-wg` directly reflects the core philosophy of the **NX9 Ecosystem** ([https://nx9.in](https://nx9.in)): + +| NX9 Principle | Core Intent | `nx9-wg` Implementation | +| :--- | :--- | :--- | +| πŸ”‘ **Operator Ownership** | Full control over binaries, configurations, databases, keys, and backups with zero dependency on cloud-hosted control planes. | 100% local operation. Private keys, configuration data, and encryption parameters never leave the operator's host. | +| πŸ–₯️ **Self-Hosting First** | Built to be deployed and operated effortlessly by a single administrator without requiring Kubernetes or external infrastructure. | Self-contained single executable. Bootstrapped with a single command (`nx9-wg init`), running seamlessly under standard systemd. | +| ⚑ **Simplicity Over Complexity** | One binary, one configuration file, one SQLite database, one administrator. | No multi-daemon orchestration, no external message queues, no Node.js runtime, no Python scripts, and zero shell wrappers. | +| πŸ›‘οΈ **Privacy by Default** | Zero analytics, zero telemetry collection, zero third-party tracking, and zero assumptions of external cloud connectivity. | No phone-home telemetry. Completely air-gapped capable with all static assets, fonts, and scripts embedded in the binary. | +| πŸ”’ **Security by Design** | Modern cryptography, strict invariants, and append-only audit logging embedded from day one. | Argon2id password hashing, SHA-256 token digests, X25519 key generation, single-admin database constraint (`CHECK (id=1)`), and strict secret redaction. | +| πŸ”§ **Operational Excellence** | Diagnostics, backup/restore, migration tools, CLI management, and comprehensive documentation built-in. | Multi-subsystem automated health inspections, atomic online SQLite `VACUUM INTO` snapshots with SHA-256 manifests, and 100% CLI parity. | +| ⏳ **Long-Term Stability** | Avoid dependency churn. Build software that remains understandable and maintainable years into the future. | Built in stable native Rust (Edition 2024), standard SQLite 3 storage, standard TOML configuration, and POSIX-compliant systemd integration. | +| 🌐 **Open Source First** | 100% free and open-source software under permissive licensing. | Dual-licensed under `MIT OR Apache-2.0`.

The NX9 Philosophy + +`nx9-wg` was conceived as a clean, high-performance, single-binary WireGuard appliance and network management engine for sovereign infrastructure. It is built upon the following foundational principles: + +### A. Self-Hosted First & Full Ownership +Network infrastructure is a critical sovereignty boundary. Administrators must have complete, unencumbered ownership of their cryptographic keys, network routing policies, and configuration data. `nx9-wg` operates entirely locally without phone-home telemetry, cloud dependencies, or external licensing servers. + +### B. Linux-Native Architecture +Rather than treating the Linux kernel as an opaque black box accessed via shell utilities, `nx9-wg` communicates directly with kernel networking subsystems using native Netlink protocols (RTNETLINK and WireGuard Generic Netlink) and direct `/proc` interfaces. + +### C. FOSS & No Vendor Lock-In +`nx9-wg` is free and open-source software dual-licensed under `MIT OR Apache-2.0`. All database schemas, configuration formats, cryptographic profiles, and backup archives use open, standard specifications (SQLite, TOML, JSON, Base64). + +### D. Zero Scripting Runtime Dependencies +The entire applicationβ€”from the HTTP/WebSocket API server and reactive SPA frontend to cryptographic key generation, QR rendering, database migrations, and kernel Netlink communicationβ€”is compiled into a single native Rust binary. There is zero runtime dependency on Node.js, npm, Electron, Python, or external shell scripts. + +### E. CLI-First & Headless Operational Simplicity +Every capability exposed by the Web UI or REST API is first available as a first-class native CLI command supporting human-readable tables as well as machine-readable JSON, YAML, and CSV formats. + +--- + +## 2. Why Not an Imperative Shell Wrapper? + +Many existing WireGuard management tools act merely as thin Web UI wrappers around command-line utilities like `wg`, `wg-quick`, `iptables`, and `ip`. This model introduces severe architectural limitations: + +1. **Fragile Process Spawning**: Shelling out to external executables (`std::process::Command`) incurs substantial overhead, introduces quoting/injection risks, and parses fragile string outputs that break across operating system versions. +2. **Lack of Authoritative State**: Relying on `/etc/wireguard/wg0.conf` text files makes atomic transactional updates, relational constraints, foreign keys, and audit logging difficult and error-prone. +3. **Configuration Drift**: Imperative changes applied directly to the kernel or configuration files easily drift out of sync with what the web management interface displays. +4. **Host Network Destruction**: Script-based firewall and routing flush commands (e.g., `iptables -F` or modifying default routing tables) often disrupt container engines (Docker, Podman), hypervisors (KVM, libvirt), or host networking. + +--- + +## 3. Core Architectural Invariants + +### 1. SQLite Desired-State Authority +The SQLite database is the single authoritative source of truth for all intended configuration state (interfaces, peers, networks, routes, firewall rules, and NAT policies). The kernel execution plane is a cache that is brought into alignment through continuous, deterministic reconciliation. + +### 2. Zero Subprocess Execution Guarantee +Production Rust code in `nx9-wg` is strictly forbidden from invoking `std::process::Command` or `tokio::process`. All kernel mutations occur via in-process Netlink sockets or `libnftables` Netfilter bindings. + +### 3. Strict Resource Ownership & Scoping +- **Firewall Rules**: Confined strictly to `table inet nx9_wg`. External tables created by Docker, Kubernetes, or host firewalls are never modified or flushed. +- **Routing**: `nx9-wg` manages only routes explicitly defined in its database or attached to its managed interfaces. Default gateway routes and unmanaged host routes are never altered. + +### 4. Single Administrator Security Model +`nx9-wg` avoids complex RBAC frameworks in favor of a strictly enforced single-administrator model locked by database constraints (`CHECK (id = 1)`). This eliminates privilege escalation, role confusion, and broken object-level authorization vulnerabilities. + +### 5. Multi-Cycle Idempotent Reconciliation +State reconciliation follows a deterministic, read-only plan phase followed by a serialized apply phase and post-apply verification.
