# Changelog

All notable changes to **NX9-WG (`nx9-wg`)** are documented here.

## [1.0.0] — 2026-08-18

NX9-WG 1.0.0 is the first production release of the native Linux WireGuard + network control plane.

### Added

- Native Linux WireGuard lifecycle management through WireGuard Generic Netlink and RTNETLINK.
- Native IPv4/IPv6 address and route management without `wg`, `wg-quick`, `ip`, `iptables`, `nft`, `sysctl`, or shell orchestration from production Rust.
- Native nftables firewall/NAT execution scoped to the managed `table inet nx9_wg` table.
- SQLite authoritative desired-state storage with reconciliation and drift correction.
- Live WireGuard telemetry including learned peer endpoints, handshake timestamps, and RX/TX counters.
- Correct separation of client-side `AllowedIPs` from server-side WireGuard Cryptokey Routing `AllowedIPs`.
- Road-warrior server peer routing derived from assigned tunnel addresses (`/32` and `/128`) unless an explicit server-side override is configured.
- Persistent WireGuard server endpoint configuration for client configuration and QR exports.
- Interface editing through the WebUI with cryptographic identity preservation.
- WebUI peer lifecycle states: Connected, Awaiting Handshake, Disconnected, Disabled, Expired, and Revoked.
- Pure Rust client configuration and QR generation.
- CLI, REST API, WebSocket, embedded SPA, diagnostics, backup/restore, and reconciliation tooling.

### Changed

- Peer API responses now merge fresh kernel telemetry instead of relying solely on cached SQLite values.
- Handshake timestamps are serialized as explicit UTC/RFC3339 values and parsed defensively by the WebUI.
- Interface edits preserve interface UUID, private key, public key, and peer associations.
- Server endpoint resolution prefers explicit export overrides, then persistent server endpoint settings, with controlled fallback behavior.
- Reconciliation detects and repairs server-side peer `AllowedIPs` drift.
- Release documentation and testing documentation are promoted to the v1.0.0 baseline.

### Fixed

- Fixed road-warrior peers incorrectly receiving client full-tunnel `AllowedIPs` (`0.0.0.0/0, ::/0`) in the server kernel Cryptokey Routing table.
- Fixed server-to-peer routing failure caused by missing `/32` peer routes in WireGuard peer configuration.
- Fixed WebUI active peers appearing Disconnected because backend `NaiveDateTime` values lacked an explicit UTC offset.
- Fixed stale peer telemetry in REST/WebUI responses.
- Fixed missing WebUI interface Edit action.
- Fixed missing persistent server endpoint for QR/config export.
- Fixed reconciliation convergence after deliberate interface-address drift.

### Networking & Firewall

- IPv4 forwarding is managed through the native Linux networking engine.
- Outbound masquerading is scoped to the WireGuard client subnet and non-WireGuard egress interfaces.
- Firewall/NAT state is reconciled atomically within the dedicated NX9 nftables table.
- Server-side peer routes and cryptokey routing are kept distinct from client routing policy.

### Validation

- Workspace test suite: **162 tests passing** at the documented release baseline.
- Comprehensive CLI suite: **203 passed / 7 skipped**.
- Native integration suite: **19 passed / 1 skipped**.
- Dedicated live-kernel suite: **23 passed / 1 skipped** in SAFE mode baseline.
- Real Android/mobile WireGuard client: **operator-verified** for VPN connectivity and full-tunnel Internet operation during v1.0.0 acceptance.
- WebUI interface editing: **operator-verified**.
- Live peer telemetry/status: **operator-verified** with connected mobile client.
- Final reconciliation: **operator-verified** with zero drift after convergence.
- External cellular/WAN road-warrior acceptance and post-reboot physical-client acceptance remain separate operational gates unless explicitly recorded in the release evidence.
