All notable changes to **NX9-WG (`nx9-wg`)** are documented here.
## [1.1.0] — 2026-09-02
### Added
- **Interface Roles**: Explicit `InterfaceRole` discriminator (`Overlay` vs `Upstream`). Primary interface `wg0` is protected from deletion and disabling.
- **Optional Third-Party Upstream Interfaces**: In-process parser and validator for standard third-party WireGuard `.conf` files (validated against ProtonVPN), creating managed `Upstream` interfaces (e.g. `proton0`) with exactly one provider peer.
- **REST API Endpoints**: Added `POST /api/v1/interfaces/upstreams/preview` (dry-run configuration validation with secret redaction), `POST /api/v1/interfaces/upstreams/import` (atomic SQLite persistence and reconciliation), and `POST /api/v1/interfaces/{id}/restart` (link teardown and re-synchronization).
- **Native CLI Commands**: Added `nx9-wg interface upstream` command suite (`list`, `show`, `import`, `status`, `enable`, `disable`, `restart`, `delete`) and `nx9-wg interface restart`.
- **Read-Only SPA CLI Console**: Embedded web-based CLI runner enforcing a strict read-only command allowlist and output secret scrubbing.
- **Reconciliation Hardening**: Added orphan kernel interface detection and removal during `apply()`, backed by empty-desired-state safety guards preventing destructive cleanup on database read failures.
- **Provider AllowedIPs Preservation**: Upstream provider peers retain full-tunnel AllowedIPs (`0.0.0.0/0, ::/0`) in WireGuard Cryptokey Routing without modifying or hijacking host Linux FIB default routes.
### Changed
- **Optional Local Listen Ports**: Changed `Interface.listen_port` to `Option<u16>` across domain models, Netlink device configuration, REST API, and SQLite database (`0005_optional_listen_port.sql`).
- **Dynamic Port Web UI**: Unspecified listen ports are rendered as `Auto (Dynamic)` rather than a fabricated `51820`.
### Fixed
- **Local Listen Port Collision (errno=-98 / EADDRINUSE)**: Fixed upstream interfaces defaulting omitted `ListenPort` to `51820`, which collided with `wg0`. Omitted listen ports now remain `None`, allowing Linux WireGuard to bind an ephemeral dynamic UDP port.
- **Reconciliation Dynamic Port Drift**: Suppressed false listen-port drift when desired `listen_port` is `None` and the kernel reports a dynamic port.
- **Provider Endpoint Port Independence**: Ensured remote destination `[Peer] Endpoint` port (e.g. `37.19.199.155:51820`) is strictly preserved and never assigned as the local interface listen port.
### Interoperability Status
- **ProtonVPN**: ProtonVPN WireGuard `.conf` files import and synchronize cleanly into Linux kernel devices (`proton0`) with dynamic local listen ports. Upstream connectivity status is classified as `interop_pending_external_validation` (pending external provider session/endpoint resolution, not an NX9-WG implementation defect).

## 1. 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 |
| :--- | :--- | :--- |
| 🔑 **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. |
| 🖥️ **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. |
| 🛡️ **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. |
| 🔒 **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. |
| 🔧 **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`. Complete freedom to inspect, audit, build, and extend. |
| ♾️ **Zero Vendor Lock-In** | Standard data formats, open protocols, and zero proprietary cloud lock-in. | Standard SQLite database, standard WireGuard `.conf` files, standard RFC-compliant JSON/YAML/CSV output formats, and open Netlink sockets. |

└─────────────┘ └─────────────┘
```
### The Six Reconciliation Lifecycle States
1. **`Plan`**: Read-only calculation of drift between SQLite and kernel.
2. **`Applying`**: In-progress dispatch of native mutations across execution planes.
3. **`Verifying`**: Querying live kernel state to confirm applied changes took effect.
4. **`Converged`**: 100% synchronization achieved with zero remaining drift.
5. **`PartialFailure`**: One or more execution planes failed during apply (e.g. permission error).
6. **`DriftRemains`**: Apply completed without fatal error, but post-verification detected unapplied state.
---
## 8. Embedded Single Page Application (SPA) & WebSockets
The `nx9-wg` frontend is a zero-dependency HTML5/CSS/JavaScript SPA embedded directly into the Rust binary:
- **Zero External Toolchains**: No Node.js, npm, Webpack, Vite, React, or external CDN dependencies.
- **Embedded In-Memory Delivery**: Bundled at compile-time via `include_str!()` and served from memory.
- **Design Tokens**: Custom CSS token system ([`crates/nx9-wg-ui/src/css.rs`](file:///home/sunil/Programs/nx9-wg/crates/nx9-wg-ui/src/css.rs)) supporting Light and Dark modes.
- **Real-Time WebSocket Stream**: Subscribes to `ws://<host>/api/v1/ws` for live handshakes and drift alerts without polling.
- **15 Interactive Views**:
1. `#dashboard` — System overview, uptime, interface/peer counts, health cards.
2. `#interfaces` — WireGuard interface CRUD, listen port, MTU, state toggles.
3. `#peers` — Enrolled peer table, real-time handshakes, profile resolution, `.conf` export, SVG QR modal.
4. `#networks` — Subnet network ranges, CIDR masks, available IP inspector.

6. `#firewall` — nftables packet filtering rules in `table inet nx9_wg`, priority sorting.
7. `#nat` — Managed subnet NAT masquerade status and instant toggle.
8. `#forwarding` — Kernel IPv4/IPv6 packet forwarding status and toggle.
9. `#reconciliation` — Real-time kernel drift overview, action plan table, interactive Apply button.
10. `#diagnostics` — Automated multi-subsystem health checks with remediation hints.
11. `#live-state` — Raw Linux Netlink telemetry, active kernel interfaces, live routing table.
12. `#settings` — Key-value appliance parameters and danger zone reset controls.
13. `#backups` — Online SQLite backup snapshots list, instant backup creation, `.db` download.
14. `#audit` — Append-only security and administrative audit trail.
15. `#administrator` — Admin account verification, password rotation, and one-time API token generation.

## 11. Security Model & Capability Isolation
### A. Single Administrator Identity
- Database-level integrity constraint: `CHECK (id = 1)` in `admins` table.
- Eliminates multi-tenant privilege escalation and role-confusion attack surfaces.
### B. Credential Protection
- **Passwords**: Hashed with Argon2id using unique cryptographic salts.
- **API Tokens**: Stored exclusively as SHA-256 digests in SQLite; raw tokens are displayed once upon creation.
- **Secret Redaction**: Private keys, preshared keys, and password hashes implement custom `std::fmt::Debug` implementations returning `[REDACTED]`.
### C. Hardened systemd Sandbox (`nx9-wg.service`)

## 12. Disaster Recovery, Backups & Upgrades
### Atomic Online Backups
- Uses SQLite `VACUUM INTO` to produce non-blocking, consistent binary database snapshots while the daemon is actively serving traffic.
- Generates SHA-256 manifest records for each snapshot.

> **Sovereign, self-hosted, Linux-native VPN and network control plane built directly around the kernel's WireGuard implementation.**
`nx9-wg` is no longer just a WireGuard management wrapper. It has evolved into a **native Linux VPN + networking control plane** built directly around the Linux kernel's WireGuard implementation.
`nx9-wg` is a native Linux VPN and networking control plane built directly around the Linux kernel's in-tree WireGuard implementation (`wireguard.ko`).
Rather than functioning as a user interface wrapper that shells out to external command-line utilities (`wg`, `ip`, `nft`, `sysctl`), `nx9-wg` provides a single self-contained binary architecture. It integrates **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**.

└── ↔️ Direct Procfs IP Forwarding (/proc/sys/net)
```
---
## Core Capabilities Beyond Interface Creation
- 🔐 **WireGuard interface and peer lifecycle** (RTNETLINK + WireGuard Generic Netlink)
- 🌐 **IPv4/IPv6 address management** (In-process `RTM_NEWADDR` / `RTM_DELADDR`)
- 🛣️ **Route management & protected route reconciliation** (Zero default-route interference)
- 🔥 **Firewall rule management** (In-process `libnftables.so.1` FFI in `table inet nx9_wg`)
- 🛡️ **Scoped NAT/masquerading** (Strictly scoped to managed WireGuard client subnets)
- ↔️ **IPv4/IPv6 forwarding** (Direct atomic `/proc/sys/net` sysctl control)
- 📡 **Live WireGuard telemetry** (Handshake timestamps, authenticated roaming endpoints, byte counters)
- 🔄 **Desired-state reconciliation** (Continuous closed-loop convergence)
- 🧭 **Drift detection** (5-subsystem read-only deterministic planning)
- ♻️ **Restart recovery** (Cold-boot reconstruction of live kernel networking from SQLite)
- 🧪 **Simulation engine** (Full macOS/Windows local development fallback)
- 🖥️ **CLI + REST API + WebSocket + SPA** (Zero-dependency embedded interface)
- 📊 **Diagnostics** (Automated health inspection across 9 subsystems with remediation hints)
- 💾 **Backup/restore** (Atomic online `VACUUM INTO` snapshots with SHA-256 manifests)
- 🔑 **Administrator/authentication/API tokens** (Argon2id, SHA-256 tokens, single-admin `CHECK (id=1)`)
- 📱 **Client profiles + generated configurations + QR** (Pure Rust SVG, PNG, and ASCII QR engine)
- 📦 **Standalone Linux deployment** (Zero scripting runtime, self-contained distribution packages)
- 🔒 **systemd capability isolation** (`CAP_NET_ADMIN`, `CAP_NET_BIND_SERVICE`, full sandbox directives)
- **Explicit Interface Roles (Overlay vs Upstream)**: Formal separation of the primary protected overlay interface (`wg0`) from optional third-party WireGuard VPN upstream interfaces (e.g. `proton0`).
- **Third-Party WireGuard .conf Import**: In-process parser and validator for standard `.conf` files (supporting single `[Interface]` and single `[Peer]`), with live configuration preview before atomic database persistence.
- **Optional Local Listen Ports**: Strict modeling of `Interface.listen_port` as `Option<u16>`, allowing Linux WireGuard to select ephemeral dynamic UDP ports when `ListenPort` is omitted from imported configurations, preventing local port collisions with `wg0` (51820).
- **WireGuard Interface & Peer Lifecycle**: Direct RTNETLINK link management (`RTM_NEWLINK`/`RTM_DELLINK`) and WireGuard Generic Netlink (`WG_CMD_SET_DEVICE`/`WG_CMD_GET_DEVICE`) with role-aware cryptokey routing.
- **Persistent Server Endpoint Settings**: Authoritative configuration of public client-reachable endpoint (`wireguard.server_host`, `wireguard.server_port`, `wireguard.server_endpoint_enabled`) automatically embedded into client exports and QR codes.
- **Strict AllowedIPs Semantic Separation**: Correctly derives server-side cryptokey routing AllowedIPs (`/32` and `/128`) from assigned tunnel addresses for Overlay peers, while preserving full-tunnel provider AllowedIPs (`0.0.0.0/0, ::/0`) for Upstream peers without mutating the host default routing table.
- **IPv4/IPv6 Address Management**: In-process `RTM_NEWADDR` and `RTM_DELADDR` Netlink execution without invoking `ip addr`.
- **Protected Route Management**: In-process routing table reconciliation protecting host default routes from accidental disruption.
- **In-Process nftables Firewall & NAT**: Transactional rule compilation via `libnftables.so.1` strictly scoped to `table inet nx9_wg`.
- **Scoped Outbound NAT Masquerade**: Automated masquerading scoped to managed WireGuard client subnets and non-WireGuard egress interfaces.
- **Atomic IP Packet Forwarding**: Direct `/proc/sys/net/ipv4/ip_forward` and IPv6 forwarding control.
- **Live Kernel Telemetry**: Live handshake timestamps, authenticated roaming endpoints, and 64-bit RX/TX byte counters merged into API and WebUI responses.
- **Closed-Loop Reconciliation**: Continuous drift detection, dry-run deterministic planning, orphan interface removal, and serialized convergence with empty-desired-state safety guards.
- **Cold-Boot Restart Recovery**: Deterministic reconstruction of live kernel networking from authoritative SQLite state upon boot.
- **Single Administrator Identity**: Database-level `CHECK (id = 1)` constraint, Argon2id password hashing, and SHA-256 API token digests.
- **Zero-Dependency Single Page Application (SPA)**: Embedded HTML5/CSS/JS frontend with dark/light themes, live WebSocket telemetry, responsive mobile-first UI, Upstream import modal with live preview, and read-only CLI console.
- **Pure Rust Client Configuration & QR**: In-process generation of standard `.conf` text and SVG, PNG, and terminal ASCII QR codes.
- **Automated Health Diagnostics**: Deep inspection across 11 subsystems with actionable remediation hints.
- **Atomic SQLite Online Backups**: Non-blocking `VACUUM INTO` snapshots with SHA-256 integrity manifests and pre-restore safety snapshots.
- **Application Subprocess Isolation**: The `nx9-wg` Rust application does not invoke `wg`, `ip`, `nft`, `sysctl`, or shell commands through `std::process::Command`. Operational administration scripts may use standard Linux utilities for deployment, diagnostics, backup, and service management.

## SQLite as the Single Authority
## 3. Core Design Principles
The foundational architectural choice in `nx9-wg` is **SQLite as the authoritative desired state**.
WireGuard is not the configuration database. The kernel is not the configuration database either.
```
SQLite
│
│ desired state
▼
nx9-wg reconciler
│
│ convergence
▼
Linux kernel
```
If the kernel state disappears after a reboot or network interface reset, the system deterministically reconstructs the entire network topology from the authoritative desired state in SQLite.
| Principle | Technical Implementation |
| :--- | :--- |
| **Operator Sovereignty** | 100% self-hosted local execution. Private keys, configuration data, and cryptographic credentials never leave the host. |
| **SQLite Authority** | SQLite in WAL mode is the single authoritative source of truth. Kernel state is reconciled to match the database. |
| **Zero Application Subprocesses** | All kernel interactions performed by the Rust application execute through native Linux Netlink sockets, `libnftables.so.1` FFI, and direct procfs writes. Operational shell scripts are separate administrative tooling. |
| **Defense in Depth** | Single administrator model (`CHECK (id=1)`), Argon2id hashing, SHA-256 token digests, HttpOnly `nx9_session` cookies, brute-force rate limiting, and strict secret redaction. |
| **Simplicity & Reliability** | Single binary, single database file, single configuration file, self-contained systemd service, and zero external runtime dependencies. |
---
## The NX9 Philosophy in Implementation
## 4. Workspace Architecture
`nx9-wg` deliberately avoids building an application around a fragile pile of external utilities:
`nx9-wg` is structured as a modular six-crate Rust workspace:
- ❌ `wg`
- ❌ `wg-quick`
- ❌ `ip`
- ❌ `iptables`
- ❌ `nft` CLI
- ❌ `sysctl` CLI
- ❌ shell orchestration
- ❌ Node.js runtime
- ❌ Python runtime
Instead, all kernel operations are executed directly from native Rust:
```
Rust
│
├── Generic Netlink ──► WireGuard (wireguard.ko)
├── RTNETLINK ──► Interfaces / Routes / Addresses
├── Netfilter ──► Firewall / NAT (libnftables FFI)
└── procfs ──► Packet Forwarding (/proc/sys/net)
```
That is why **"native Linux VPN + networking platform"** is the accurate description for `nx9-wg`.
- [**`crates/nx9-wg-core`**](crates/nx9-wg-core): Typed domain models (`Interface`, `Peer`, `Network`, `Route`, `FirewallRule`, `Setting`, `ServerEndpointSettings`, `Admin`), RFC-compliant validators, cryptography (Argon2id, SHA-256, X25519), and hierarchical configuration loader.
- [**`crates/nx9-wg-db`**](crates/nx9-wg-db): Authoritative SQLite store, 13 relational tables, automated migrations via `sqlx`, and repository implementations in WAL mode.
- [**`crates/nx9-wireguard`**](crates/nx9-wireguard): WireGuard Generic Netlink execution, RTNETLINK link management, client `.conf` generator, and pure Rust QR engine (SVG, PNG, ASCII).
- [**`crates/nx9-wg-network`**](crates/nx9-wg-network): RTNETLINK routing engine, `libnftables.so.1` Netfilter integration in `table inet nx9_wg`, and direct procfs packet forwarding.
- [**`crates/nx9-wg-api`**](crates/nx9-wg-api): Axum REST router, WebSocket real-time broadcaster, session/token authentication, deterministic IP allocator, and reconciliation engine.
- [**`crates/nx9-wg-ui`**](crates/nx9-wg-ui): Pure CSS design system, responsive stylesheet compiler, view models, and embedded SPA assets.
- **`src/main.rs`**: Root executable CLI providing full subcommand coverage and daemon orchestration.

| **LIVE Kernel Verification** | **Framework Ready** | SAFE mode (`LIVE=0`) verified; dedicated host ready via `LIVE=1` |
When generating client configuration files (`.conf`) and QR codes, `nx9-wg` automatically embeds the public or reachable server endpoint address where WireGuard clients connect across the Internet or WAN.
### Setting Keys in SQLite
| Key | Type | Description | Default | Example |
| :--- | :--- | :--- | :--- | :--- |
| `wireguard.server_host` | String | Public/reachable server hostname or IP address (DNS hostname, IPv4, or IPv6). Must not contain a port. | Empty | `vpn.thakares.com` or `203.0.113.10` or `2001:db8::10` |
| `wireguard.server_port` | u16 | Public reachable UDP port where clients connect (`1..=65535`). | `51820` | `51820` |
| `wireguard.server_endpoint_enabled` | Boolean | Whether the persistent endpoint is used as the default for client exports. | `true` | `true` |
| `server_endpoint` | String | Legacy formatted endpoint fallback (`host:port` or `[ipv6]:port`). | Empty | `vpn.thakares.com:51820` |
| `public_endpoint` | String | Legacy secondary fallback. | Empty | `vpn.thakares.com:51820` |
### Authoritative Resolution Precedence
1. **Explicit per-request / per-export override**: Passed via `--endpoint <ENDPOINT>` in the CLI or `?endpoint=<ENDPOINT>` in the REST API.
2. **Persistent structured settings**: `wireguard.server_host` + `wireguard.server_port` when `wireguard.server_endpoint_enabled` is `true` and `host` is non-empty.
3. **Legacy `server_endpoint` setting**: If present and non-empty.
4. **Legacy `public_endpoint` setting**: If present and non-empty.
5. **Actionable configuration error**: Directs the administrator to configure the server endpoint in Settings or provide `--endpoint`.
> **Separation Invariant**: The public server endpoint port (`wireguard.server_port`) is conceptually separate from the local WireGuard kernel interface UDP `listen_port` (which may bind locally behind NAT, port-forwarding, or intermediate firewalls).

## 9. Native CLI Command Reference
The `nx9-wg` binary provides native CLI coverage across all 18 command groups:
```bash
# 1. System Settings & Server Endpoint
nx9-wg system settings set wireguard.server_host vpn.thakares.com
nx9-wg system settings set wireguard.server_port 51820
nx9-wg system settings set wireguard.server_endpoint_enabled true
# 2. Interface Creation, Editing & Restart
nx9-wg interface create wg0 --address-v4 10.100.0.1/24 --port 51820 --mtu 1420
nx9-wg interface update wg0 --mtu 1420
nx9-wg interface restart wg0
# 3. Third-Party Upstream Management (e.g. ProtonVPN)
nx9-wg interface upstream import proton0 --file /path/to/protonvpn.conf

## 10. Peer Creation & Cryptokey Routing Semantics
`nx9-wg` strictly enforces the architectural separation between server-side cryptokey routing and client-side routing policy:
### Server-Side Cryptokey Routing (`AllowedIPs`)
For a road-warrior peer assigned address `10.100.0.2/32`, the server kernel's WireGuard peer configuration receives:
```ini
[Peer]
PublicKey = <CLIENT_PUBLIC_KEY>
AllowedIPs = 10.100.0.2/32
```
*This ensures the Linux kernel cryptographically binds packet transmission and reception specifically to `10.100.0.2/32` and prevents peer routing collisions.*
### Generated Client Configuration (`.conf`)
The generated client configuration file exported for the client device contains:
```ini
[Interface]
PrivateKey = <CLIENT_PRIVATE_KEY>
Address = 10.100.0.2/32
DNS = 1.1.1.1, 1.0.0.1
MTU = 1280
[Peer]
PublicKey = <SERVER_PUBLIC_KEY>
Endpoint = vpn.thakares.com:51820
AllowedIPs = 0.0.0.0/0, ::/0
PersistentKeepalive = 25
```
---
## 11. Authentication, Sessions & WebSockets
- **Single Administrator Identity**: Locked with `CHECK (id = 1)`. Passwords derived using memory-hard Argon2id.
- **Session Security**: Authenticated browser sessions receive an `HttpOnly`, `SameSite=Strict`, `Path=/` cookie named `nx9_session`.
- **API Tokens**: Cryptographically hashed tokens (`nx9_<uuid>_<random>`). Only the SHA-256 digest is stored in SQLite.
- **Brute-Force Rate Limiting**: Exponential backoff and IP-based rate limiting (5 failed attempts per 15-minute sliding window triggers `HTTP 429 Too Many Requests`).
- **Real-Time WebSocket Protocol (`/api/v1/ws`)**: Authenticates seamlessly using the browser's `nx9_session` HttpOnly cookie or `Authorization: Bearer <token>` header, streaming real-time events: `AuditEvent`, `InterfaceChanged`, `PeerChanged`, `PeerHandshake`, and `SettingsChanged`.
---
## 12. Quality Assurance & Verification Evidence
All release quality gates have been executed and verified on Debian Linux:
| Quality Gate | Command | Result |
| :--- | :--- | :--- |
| **Formatting** | `cargo fmt --all -- --check` | **PASS** (0 errors) |
| **Compilation** | `cargo check --workspace --all-targets` | **PASS** (0 errors) |
| **Clippy Linting** | `cargo clippy --workspace --all-targets --all-features -- -D warnings` | **PASS** (0 warnings) |
| **Workspace Test Suite** | `cargo test --workspace --all-targets` | **PASS** (All 195 tests passing) |
| **CLI Test Suite** | `cargo test --test test_cli_commands` | **PASS** (12 tests passing) |
| **Release Compilation** | `cargo build --release --workspace` | **PASS** (Optimized release binary) |
| **Production Server Acceptance** | Physical Android WireGuard client connection | **VERIFIED** (Live handshake and RX/TX telemetry confirmed) |

| [`scripts/package-release.sh`](scripts/package-release.sh) | **Release Packaging**: Bundles binary, systemd unit, default configuration, docs, and installer into `.tar.gz` and `.tar.xz` release archives. |
| [`scripts/deploy.sh`](scripts/deploy.sh) | **Production Deployment**: Validates the source release binary, backs up the active binary to `/usr/local/bin/nx9-wg.backup.<timestamp>`, performs a controlled replacement, checks UDP socket conflicts safely, updates the systemd unit, restarts the service, and verifies the active version. |
| [`scripts/rollback.sh`](scripts/rollback.sh) | **Production Rollback**: Automatically discovers deployment backups in `/usr/local/bin/nx9-wg.backup.*` and safely rolls back the active binary with service verification. |
| [`scripts/diagnose.sh`](scripts/diagnose.sh) | **Production Diagnostics**: Collects a secret-safe snapshot of service health, journal logs, active UDP socket listeners, kernel WireGuard state (`wg show`), nftables rules, sysctl IP forwarding, and appliance diagnostics. |
| [`scripts/backup-source.sh`](scripts/backup-source.sh) | **Source Archive Backup**: Creates a timestamped `.tar.xz` source snapshot excluding `target/` and temporary databases while preserving `.git/` history. |
| [`scripts/install.sh`](scripts/install.sh) | **Host Installer**: Bootstraps directories, config template, initial administrator, and systemd service unit. |
| [`scripts/uninstall.sh`](scripts/uninstall.sh) | **Host Uninstaller**: Safely removes binary and service unit while preserving configuration and SQLite database by default (`--purge` for teardown). |

## 14. Security Considerations
- **Application Subprocess Isolation**: `nx9-wg` does not spawn external shell commands or utilities from the Rust application, eliminating command-injection and shell-escaping exposure from application-level command execution. Operational scripts are separate administrative tooling.
- **Firewall Scoping**: All nftables operations are confined to `table inet nx9_wg`. External tables from Docker, Kubernetes, or host firewalls are completely untouched.
- **Secret Redaction**: Private keys, preshared keys, password hashes, and token digests are masked (`[REDACTED]`) in `Debug` formatters, CLI outputs, and API responses.
- **Strict File Permissions**: The data directory and SQLite database are locked to `0700` and `0600` (`root:root`).
- **Client Configuration Protection**: Exported `.conf` files and QR codes contain sensitive client private keys and must be delivered securely to client devices.

`nx9-wg-db` provides the authoritative SQLite persistence layer for the `nx9-wg` native Rust WireGuard management system.
## Architectural Boundaries
- **Authoritative State**: SQLite is the authoritative persistent store for `nx9-wg` desired state. It stores what the system intends the network, interfaces, peers, routes, firewall rules, administrator credentials, sessions, tokens, and settings to be.
- **Separation of Concerns**: SQLite records desired configuration only. Live kernel state (WireGuard interface status, handshake counters, packet counters, live nftables rules, live kernel routes) is queried directly from Linux kernel subsystems in later phases.
- **SQL Encapsulation**: All SQL queries, SQLite connection lifecycle, migrations, and row conversions are strictly encapsulated inside `nx9-db`. Neither `nx9-core`, `nx9-api`, `nx9-ui`, `nx9-wireguard`, nor `nx9-network` issue SQL directly.

## Database Schema (12 Tables)
## Database Schema (13 Tables)
1. `admin` — Single administrator identity (`CHECK (id = 1)`), Argon2id password hash, TOTP secrets, and login timestamp.
2. `sessions` — Admin web sessions (`ON DELETE CASCADE`).
3. `login_attempts` — IP-based login attempt tracking for brute-force rate limiting.
4. `api_tokens` — Hashed API tokens for automation (`ON DELETE CASCADE`).

5. `interfaces` — Desired WireGuard interfaces (`wg0`, `proton0`, etc.), role (`overlay`, `upstream`), private/public keys, optional listen port (`NULL` for dynamic kernel allocation), IPv4/IPv6 CIDRs, MTU, DNS.
6. `peers` — Desired WireGuard peer definitions, classifications (`road_warrior`, `site_gateway`, `server`, `relay`), states (`active`, `disabled`, `revoked`, `expired`), profiles (`full_tunnel`, `split_tunnel`, `custom`), public/private/preshared keys, AllowedIPs, endpoints, and persistent keepalives (`ON DELETE CASCADE`).
7. `networks` — Named network CIDRs for routing and organization.
8. `routes` — Desired kernel routing rules (`ON DELETE SET NULL`).

11. `audit_events` — Append-only operational audit log with event filtering and pagination.
12. `backups` — Backup metadata and manifest checksum records.
13. `client_profiles` — Device, connection, and MTU transport profile specifications with built-in protections.
## Migration Strategy
- Migrations are defined in `crates/nx9-db/migrations/` and embedded at compile time via `sqlx::migrate!("./migrations")`.
- Migrations are defined in `crates/nx9-wg-db/migrations/` and embedded at compile time via `sqlx::migrate!("./migrations")`:
- `0001_initial_schema.sql` — Initial relational schema.
- `0002_wiregui_schema.sql` — WireGUI capabilities and profile structures.
- `0003_server_endpoint_settings.sql` — Persistent server endpoint settings.
- `0004_interface_roles.sql` — Interface roles (`overlay` and `upstream`).
- `0005_optional_listen_port.sql` — Nullable `listen_port` for ephemeral kernel port selection.
- Migrations are executed automatically via `store.migrate().await?`.
- Migrations are tracked in the `_sqlx_migrations` table for idempotency.

```
### A. Role Discriminator & Invariants
- **`InterfaceRole::Overlay`**: The primary private WireGuard overlay network. Exactly one instance exists (`wg0`). It binds to an explicit listen port (`51820`), hosts enrolled client peers, and is protected from deletion or disabling.
- **`InterfaceRole::Upstream`**: Optional third-party WireGuard VPN interfaces (e.g. `proton0`). Zero or more instances may exist concurrently. Each Upstream interface connects NX9-WG to an external service provider through exactly one provider peer.
### B. Optional Local Listen Port & Ephemeral Kernel Binding
- `Interface.listen_port` is modeled as `Option<u16>`.
- Standard third-party `.conf` imports (e.g. ProtonVPN) omit `[Interface] ListenPort`. NX9-WG preserves `listen_port = None` without defaulting to `51820`.
- In `configure_device`, omitting the `WireguardAttribute::ListenPort` Netlink attribute signals the Linux kernel to assign an ephemeral dynamic UDP port automatically.
- This prevents local UDP port contention and allows `wg0` (51820) and `proton0` (dynamic) to coexist without `-EADDRINUSE` errors.
- Dynamic kernel ports produce 0 false drift actions in the reconciliation engine when desired `listen_port` is `None`.
### C. Cryptokey Routing vs. Linux FIB Default Routes
- An Upstream provider peer often specifies `AllowedIPs = 0.0.0.0/0, ::/0` in its `.conf`.
- In WireGuard, `AllowedIPs` defines the device-level cryptokey packet routing filter; it does **not** install a Linux kernel route.
- NX9-WG preserves `0.0.0.0/0, ::/0` on the `proton0` WireGuard device without modifying the server's Linux FIB default gateway (`192.168.1.1`).
- The provider endpoint (`37.19.199.155:51820`) remains reachable via the host physical WAN interface.
### D. NAT Masquerade Isolation
- Outbound NAT masquerading compiled into `table inet nx9_wg` is strictly scoped to Overlay client subnets (`10.100.0.0/24`).
- Upstream tunnel addresses (`10.2.0.2/32`) are not treated as client subnets and do not trigger unsolicited global masquerading.

## Persistent WireGuard Server Endpoint Configuration
When generating client `.conf` configurations and QR codes, `nx9-wg` embeds the public or reachable server endpoint address so client devices can reach the server. This is managed through persistent settings in SQLite.
### Settings Keys
| Key | Type | Description | Default | Example |
| :--- | :--- | :--- | :--- | :--- |
| `wireguard.server_host` | String | Public/reachable server hostname or IP address (DNS hostname, IPv4, or IPv6). Must not contain a port. | Empty | `vpn.thakares.com` or `203.0.113.10` or `2001:db8::10` |
| `wireguard.server_port` | u16 | Public reachable UDP port where clients connect. | `51820` | `51820` |
| `wireguard.server_endpoint_enabled` | Boolean | Whether the persistent server endpoint is used as the default for client exports. | `true` | `true` |
| `server_endpoint` | String | Legacy formatted endpoint fallback (`host:port` or `[ipv6]:port`). | Empty | `vpn.thakares.com:51820` |
| `public_endpoint` | String | Legacy secondary fallback. | Empty | `vpn.thakares.com:51820` |
### Important Architectural Invariants
- **Public Endpoint vs. Interface Listen Port**: The public server endpoint (`wireguard.server_host` and `wireguard.server_port`) is the external address that clients use to connect across the Internet or WAN. It is conceptually separate from the WireGuard interface's local kernel UDP `listen_port` (which may sit behind NAT, port-forwarding, or a reverse proxy).
- **Authoritative Resolution Precedence**:
1. **Explicit per-request / per-export override**: Passed via `--endpoint <ENDPOINT>` in the CLI or `?endpoint=<ENDPOINT>` in the REST API.
2. **Persistent structured settings**: `wireguard.server_host` + `wireguard.server_port` when `wireguard.server_endpoint_enabled` is `true` and host is non-empty.
3. **Legacy `server_endpoint` setting**: If present and non-empty.
4. **Legacy `public_endpoint` setting**: If present and non-empty.
5. **Actionable configuration error**: If no endpoint is configured, generation fails with an actionable error directing the administrator to configure the server endpoint in Settings or provide an explicit override.
### Configuring via CLI
```bash
# Configure the persistent server endpoint:
nx9-wg system settings set wireguard.server_host vpn.thakares.com
nx9-wg system settings set wireguard.server_port 51820
nx9-wg system settings set wireguard.server_endpoint_enabled true
# Export a client configuration using the persistent default:
nx9-wg peer config <PEER_UUID>
# Generated output contains: Endpoint = vpn.thakares.com:51820
# Export with a temporary one-off override (does not modify persistent settings):
nx9-wg peer config <PEER_UUID> --endpoint custom.backup-vpn.com:51820
# Generated output contains: Endpoint = custom.backup-vpn.com:51820
```

## Secret Handling & Docker Secrets
- **Never Persisted in Cleartext**: `NX9_WG_ADMIN_PASSWORD` is hashed into SQLite using Argon2id during initialization and is never written to disk, config files, or logs.
- **Docker Secrets**: In container environments, mount Docker secrets to `/run/secrets/nx9_wg_admin_password` and specify `NX9_WG_ADMIN_PASSWORD_FILE=/run/secrets/nx9_wg_admin_password`.

# NX9-WG Stress Test --- Remote LAN Multi-Path Integration
**Project:** NX9-WG\
**Test Type:** Integration / Stress Test\
**Status:** PASS\
**Date:** 2026-08-19\
**Purpose:** Validate robust remote access to a protected LAN through
NX9-WG across substantially different underlying network paths.
------------------------------------------------------------------------
## 1. Executive Summary
This test validates that `nx9-wg` can provide authenticated, routed
access to a remote `192.168.1.0/24` LAN while the WireGuard client uses
different and independent Internet/access-network paths.
The test deliberately exercised NX9-WG through:
1. Cellular 5G → mobile WAN AP → laptop.
2. Airtel Wi-Fi → Pixel Wi-Fi Station + Access Point concurrency →
laptop.
3. A separate Wi-Fi network → laptop.
In all tested paths, the same NX9-WG peer successfully established the
VPN and reached hosts and services on the protected LAN.
The strongest validation was successful interactive SSH access to
`192.168.1.200`, in addition to ICMP, HTTP, network filesystem access,
and LAN host discovery.
**Overall result: PASS.**
------------------------------------------------------------------------
## 2. Test Objective
Validate that NX9-WG:
- establishes a WireGuard tunnel independently of the client's
underlying access network;
- correctly routes traffic from a remote peer to the protected LAN;
- handles different upstream NAT/network topologies;
- provides access to multiple LAN hosts rather than only a single
endpoint;
- supports real application traffic over the tunnel;
- preserves connectivity when the client changes access-network
topology;
- does not require changes to the protected LAN or ISP router
configuration.
This test is intended as an **integration and robustness validation**,
not as a throughput benchmark.
------------------------------------------------------------------------
## 3. Network Topology
### Protected LAN
``` text
192.168.1.0/24
```
Representative hosts:
``` text
192.168.1.1 Airtel AirFiber / Nokia AAP321NK
192.168.1.200 Debian server / Thakares IoT Hub
```
### NX9-WG peer
``` text
WireGuard interface: Office-Laptop
WireGuard address: 10.100.0.6/32
MTU: 1280
```
The important architectural property is that the client-side underlay
network can change while the WireGuard overlay identity and protected
LAN remain unchanged.
------------------------------------------------------------------------

```
## Procedure
1. Mobile phone connected to cellular 5G.
2. Mobile phone provided WAN/AP connectivity.
3. Laptop connected to the mobile AP.
4. NX9-WG VPN was enabled.
5. Laptop received an Internet address on the mobile network.
6. Remote LAN routes became reachable through NX9-WG.
## Observed client addressing
``` text
wlan0: 10.137.106.48/24
WireGuard: 10.100.0.6/32
```
## Validation
### Internet
``` text
ping google.com
```
Result:
``` text
0% packet loss
```
### LAN host
``` text
ping 192.168.1.200
```
Result:
``` text
0% packet loss
```
### LAN discovery
An initial ordinary `nmap -sP 192.168.1.0/24` did not discover hosts
while the LAN was only reachable through the routed WireGuard path.
Individual routed hosts were nevertheless reachable.
This was subsequently validated more comprehensively in Scenario C using
`nmap` with the active routed path.
------------------------------------------------------------------------
# 5. Test Scenario B --- Wi-Fi STA + AP Concurrency
This was the more interesting underlay test.
The Pixel device supports simultaneous Wi-Fi client (STA) and Access
Point operation.
## Path

▼
192.168.1.0/24
```
## Procedure
1. Pixel connected to Airtel Wi-Fi.
2. Pixel simultaneously enabled its Access Point.
3. Laptop connected to the Pixel AP.
4. Laptop enabled NX9-WG.
5. No cellular Internet was used.
6. Remote LAN access worked immediately.
## Result
**PASS**
This demonstrates that NX9-WG remains functional when the client reaches
the Internet through a Wi-Fi STA/AP-concurrent intermediate device.
No cellular fallback was required.
------------------------------------------------------------------------
# 6. Test Scenario C --- Remote LAN Application and Host Validation
A further test was performed from an external Wi-Fi network.
## Client addressing
``` text
wlan0:
10.24.3.48/24
WireGuard:
10.100.0.6/32
```
The underlying Wi-Fi network therefore differed from the protected LAN.
## Internet validation
``` bash
ping nx9.in
```
Observed:
``` text

```
## LAN server validation
``` bash
ping 192.168.1.200
```
Observed:
``` text
3 packets transmitted
3 received
0% packet loss
min/avg/max/mdev:
88.959 / 95.690 / 105.145 / 6.882 ms
```
------------------------------------------------------------------------
# 7. LAN Host Discovery
The routed LAN was scanned using:
``` bash
nmap -sP 192.168.1.0/24
```
The following 17 hosts were discovered:
``` text
192.168.1.1
192.168.1.3
192.168.1.4
192.168.1.5
192.168.1.6
192.168.1.7
192.168.1.8
192.168.1.9
192.168.1.10
192.168.1.13
192.168.1.18
192.168.1.20
192.168.1.60
192.168.1.64
192.168.1.100
192.168.1.152
192.168.1.200
```
Result:
``` text
17 hosts up
```
This is significant because it validates routed access to the LAN as a
network segment rather than connectivity to only one predefined host.
------------------------------------------------------------------------
# 8. Application-Level Validation
## HTTP
The NX9-WG client successfully accessed:
``` text
http://192.168.1.200:8008
```
The Thakares IoT Hub web application loaded successfully.
## Network filesystem
The Linux desktop successfully accessed the remote Debian server:
``` text
192.168.1.200
/home/sunil
```
## SSH
The strongest application-level validation was:
``` bash
ssh 192.168.1.200
```
which produced a normal interactive login:
``` text
Linux thakares 6.12.101+deb13-rt-amd64
Debian GNU/Linux
x86_64
```
The remote shell was successfully entered and exited normally.
This confirms:
- TCP connectivity;
- routing;
- return-path routing;
- firewall/forwarding compatibility;
- SSH service accessibility;
- stable encrypted transport;
- real bidirectional application traffic.

------------------------------------------------------------------------
# 10. Key Finding
The same NX9-WG peer:
``` text
10.100.0.6/32
```
successfully accessed:
``` text
192.168.1.0/24
```
while its underlying client network changed.
Examples included:
``` text
10.137.106.0/24
10.24.3.0/24
```
This demonstrates a clean separation between:
- **underlay:** whatever network currently provides Internet
connectivity;
- **overlay:** the authenticated NX9-WG tunnel;
- **protected network:** the routed `192.168.1.0/24` LAN.
The protected LAN required no modification for these tests.
------------------------------------------------------------------------
# 11. Why This Is a Meaningful Stress Test
This test does not attempt to measure maximum WireGuard throughput.
Instead, it stresses the **network topology and routing assumptions** of
NX9-WG.
The tested paths introduce:
- different client networks;
- different NAT environments;
- mobile AP routing;
- Wi-Fi STA/AP concurrency;
- additional network hops;
- remote access to an entire private subnet;
- multiple simultaneous LAN destinations;
- multiple application protocols.
The successful results indicate that NX9-WG is not dependent on a
particular client access network.
------------------------------------------------------------------------
# 12. Airtel LAN Collision Use Case
The test originated from a practical problem involving an Airtel
AirFiber Nokia AAP321NK using:
``` text
192.168.1.1
```
which overlaps with the existing home LAN addressing.
Instead of modifying the ISP-controlled router configuration, NX9-WG
provided an independent routed management path:
``` text
External network
│
▼
NX9-WG
│
▼
192.168.1.0/24
│
├── 192.168.1.1
├── 192.168.1.200
└── other LAN hosts
```
This demonstrates a practical operational benefit of the NX9-WG
architecture: remote authenticated access to infrastructure can remain
available without requiring ISP router reconfiguration.
------------------------------------------------------------------------
# 13. What This Test Does Not Establish
This test should **not** be interpreted as a performance benchmark.
The following remain outside the scope of this test:
- maximum throughput;
- sustained high-volume transfer;
- CPU utilisation;
- simultaneous high-volume traffic from many peers;
- large-scale concurrent peer testing;
- packet-loss recovery under severe loss;
- roaming during an active session;
- MTU/fragmentation testing under load;
- IPv6 routed-LAN testing;
- server restart/recovery testing;
- client sleep/resume testing;
- long-duration soak testing.
These should be covered by separate tests if required.
------------------------------------------------------------------------
# 14. Recommended Future Stress Tests
Future NX9-WG validation can extend this matrix with:
### Performance
``` text
iperf3
```
- TCP throughput;
- UDP throughput;
- bidirectional traffic;
- sustained transfers.
### Reliability
- 1-hour soak test;
- 24-hour soak test;
- repeated tunnel reconnects;
- server restart;
- client suspend/resume.
### Mobility
- Wi-Fi → 5G;
- 5G → Wi-Fi;
- AP changes while tunnel is active;
- changing NAT environments.
### Scale
- multiple simultaneous peers;
- multiple LAN destinations;
- concurrent HTTP/SSH/file traffic.
### Network edge cases
- MTU stress;
- fragmentation;
- packet loss;
- high latency;
- jitter;
- IPv6.
------------------------------------------------------------------------
# 15. Final Assessment
**NX9-WG Remote LAN Multi-Path Integration Test: PASS**
The implementation successfully provided authenticated routed access
from externally connected clients to the protected `192.168.1.0/24` LAN
across multiple substantially different network paths.
The successful SSH session to `192.168.1.200`, access to the IoT Hub,
network filesystem access, and discovery of 17 LAN hosts provide strong
practical evidence that the VPN is functioning as a complete remote-LAN
connectivity solution rather than merely establishing a WireGuard
handshake.
------------------------------------------------------------------------
**Test conclusion:**
> NX9-WG successfully maintained functional remote access to the
> protected LAN independently of the underlying client access network,
> including cellular, Wi-Fi, and Wi-Fi STA/AP concurrent paths.

## 3. Interactive Modals & Client Transport Profiles
## 3. Interactive Modals & Upstream Workflows
### A. Client Profile & MTU Resolution Modal
When enrolling a new peer (`#peers`), the modal automatically queries `/api/v1/client-profiles/resolve` based on selected Device (Android, iOS, Linux, Windows, macOS) and Connection (Mobile Cellular 4G/5G, Wi-Fi, Wired Ethernet) to determine optimal MTU (1280 vs 1360 vs 1420) and persistent keepalive (25s).
### B. Client Export & QR Code Modal
Displays both:
1. **Interactive Vector QR Code**: Inline SVG rendering for scanning directly with the official WireGuard mobile app.
2. **Downloadable `.conf` File**: Standard WireGuard client configuration file formatted for instant download or clipboard copy.
When opening the export modal for a peer, the UI automatically:
1. Pre-populates the **Server Endpoint** field using the persistent settings (`wireguard.server_host` and `wireguard.server_port`) configured under Settings.
2. Displays a `"Default from Server Settings"` badge indicating persistent configuration source.
3. Automatically triggers client `.conf` and QR code generation on modal open without requiring manual typing.
4. Allows the administrator to enter a temporary one-off endpoint override directly in the modal for specialized network requirements without mutating global server settings.
5. Displays both:
- **Interactive Vector QR Code**: Inline SVG rendering for scanning directly with the official WireGuard mobile app.
- **Downloadable `.conf` File**: Standard WireGuard client configuration file formatted for instant download or clipboard copy.
### C. One-Time API Token Delivery Modal
### C. Third-Party Upstream Import Modal (`#interfaces`)
The "+ Create Interface" modal provides a dedicated **Import Upstream VPN** tab:
1. Accepts interface name (e.g. `proton0`) and raw `.conf` content from third-party VPN providers (e.g. ProtonVPN).
2. Provides a **Preview Configuration** button triggering `/api/v1/interfaces/upstreams/preview` to dry-run validate the configuration and display parsed tunnel addresses, DNS, MTU, listen port (showing `Auto (Dynamic)` when omitted), and provider peer details before writing to SQLite.
3. Secret redaction: Private keys and PSKs are never echoed back in preview responses or displayed in cleartext in the UI.
4. On submission, atomically saves desired state, provisions the kernel interface, and triggers reconciliation.
### D. Embedded Read-Only CLI Console (`#interfaces`)
Provides an in-browser interactive terminal to execute read-only operational and status commands (e.g., `nx9-wg interface upstream list`, `nx9-wg diagnostics all`). Enforces a strict server-side command allowlist and output secret sanitizer.
### E. One-Time API Token Delivery Modal
Generates a new API token, calculates its SHA-256 digest for SQLite storage, and presents the raw token string once in an interactive modal with a copy button.

## 2. SAFE Mode (`LIVE=0`) vs Real-Kernel Mode (`LIVE=1`)
To guarantee safety when developing on unprivileged developer workstations:
### SAFE Mode (`LIVE=0` — Default)
- Uses real in-memory SQLite stores and dry-run Netlink message builders.
- Validates CLI parsers, JSON/YAML/CSV output formatters, route equality rules, and read-only reconciliation planning.
- Automatically skips live kernel mutation steps that require root or `CAP_NET_ADMIN`.
### Real-Kernel Mode (`LIVE=1` — Dedicated Host Only)
- Requires `root` or `CAP_NET_ADMIN` in a dedicated, disposable Linux VM.
- Creates real kernel WireGuard interfaces (e.g. `nx9t...`), attaches IPv4/IPv6 addresses, installs routes in the kernel routing table, configures `table inet nx9_wg` in Netfilter, and validates live handshake telemetry.
---
## 3. Automated Subprocess & Secret Audits
Every verification run executes strict source-level security audits:
1. **Subprocess Audit**: Confirms zero instances of `std::process::Command`, `tokio::process::Command`, `Command::new`, or shell scripts in production Rust crates.
2. **Secret Redaction Audit**: Confirms that password hashes, private keys, preshared keys, and token hashes are never printed in human-readable status outputs or logs.
3. **Environment Audit**: Confirms that all recognized environment variables strictly observe the `NX9_WG_*` namespace.

# nx9-wg Development Verification Gate
# ==============================================================================
# PURPOSE:
# Executes the full development and release quality gate suite in sequence:
# 1. Formatting verification (cargo fmt --all -- --check)
# 2. Workspace compilation (cargo check --workspace --all-targets)
# 3. Strict Clippy linting (cargo clippy --workspace --all-targets --all-features -- -D warnings)
# 4. Complete workspace unit & integration tests (cargo test --workspace --all-targets)
# 5. Comprehensive CLI verification (scripts/test-cli-comprehensive.sh)
#
# PREREQUISITES:
# - Rust toolchain (cargo, rustc, rustfmt, clippy)
#
# BEHAVIOR:
# - 100% Non-destructive.
# - Returns exit code 0 if all checks pass.
# - Returns non-zero exit code immediately on any failure.
#
# USAGE:
# bash scripts/verify.sh
# ./scripts/verify.sh
# ==============================================================================
