+# EasyTier Domain Context
+
+## Module layers
+
+`easytier-core` layers dependencies from `foundation` upward through the
+portable networking domains. `foundation` contains infrastructure Modules
+that have no dependency on a networking domain and may be used by any higher
+layer.
+
+## Operation broker
+
+An operation broker owns the lifecycle of asynchronous work submitted by an
+external caller to core. It allocates opaque operation IDs, arbitrates
+completion, cancellation, and disposal, retains terminal outcomes, and
+publishes a batch-drainable completion queue.
+
+The broker does not interpret operation kinds, outcomes, resources, wire
+formats, or domain errors. Each domain Module owns those semantics and composes
+the broker under the same lock as any state that must change atomically with an
+operation transition.
+
+Host capability operations use a separate seam. They turn Host readiness into
+Rust task wakeups and do not share the caller-to-core broker state machine.
+
+## Compact compatibility Host
+
+A compact compatibility Host retains accepted values in the authoritative TOML
+model for management readback, while the shared host-aware normalization path
+omits capabilities that the compact runtime cannot execute. Omitted settings
+are silent no-ops and must not be advertised as live network capabilities.

+   ```bash
+   git clone https://github.com/EasyTier/EasyTier.git
+   cd EasyTier
+   ```
+
+2. Install dependencies:
+   ```bash

+## Project Structure
+
+```
+easytier/          # Core functionality and libraries
+easytier-web/      # Web dashboard and frontend
+easytier-gui/      # Desktop GUI application
+.github/workflows/ # CI/CD configuration files
+```
+
+## Build Guide
+
+### Building Core
+
+```bash
+# Standard build
+cargo build --release
+
+# Platform-specific builds
+cargo build --release --target x86_64-unknown-linux-musl     # Linux x86_64
+cargo build --release --target aarch64-unknown-linux-musl    # Linux ARM64
+cargo build --release --target x86_64-apple-darwin           # macOS x86_64
+cargo build --release --target aarch64-apple-darwin          # macOS M1/M2
+cargo build --release --target x86_64-pc-windows-msvc        # Windows x86_64
+```
+
+Build artifacts: `target/[target-triple]/release/`
+
+### Building the WASI core
+
+```bash
+script/build-wasi-core.sh
+```
+
+This builds the `easytier-core` Go-host profile for `wasm32-wasip1`, then
+optimizes it with the pinned official Binaryen release. Binaryen is downloaded
+once into `target/binaryen/` and verified by SHA-256; set `WASM_OPT` to use an
+existing matching binary.
+
+### Building GUI
+
+```bash
+# 1. Build frontend
+pnpm -r build
+
+# 2. Build GUI application
+cd easytier-gui
+
+# Linux
+pnpm tauri build --target x86_64-unknown-linux-gnu
+
+# macOS
+pnpm tauri build --target x86_64-apple-darwin      # Intel
+pnpm tauri build --target aarch64-apple-darwin     # Apple Silicon
+
+# Windows
+pnpm tauri build --target x86_64-pc-windows-msvc   # x64
+```
+
+Build artifacts: `easytier-gui/src-tauri/target/release/bundle/`
+
+### Building Mobile
+
+```bash
+# 1. Install Android targets
+rustup target add aarch64-linux-android
+rustup target add armv7-linux-androideabi
+rustup target add i686-linux-android
+rustup target add x86_64-linux-android
+
+# 2. Build Android application
+cd easytier-gui
+pnpm tauri android build
+```
+
+Build artifacts: `easytier-gui/src-tauri/gen/android/app/build/outputs/apk/universal/release/`
+
+### Build Notes
+
+1. Cross-compilation for ARM/MIPS requires additional setup
+2. Windows builds need correct DLL files
+3. Check `.github/workflows/` for detailed build configurations
+
+## Development Workflow
+
+1. Create a feature branch from `develop`:
+   ```bash
+   git checkout develop
+   git checkout -b feature/your-feature-name
+   ```
+
+2. Make your changes following our coding standards
+
+3. Write or update tests as needed
+
+4. Use conventional commit messages:
+   ```
+   feat: add new feature
+   fix: resolve bug
+   docs: update documentation
+   test: add tests
+   chore: update dependencies
+   ```
+
+5. Submit a pull request to `develop`
+
+## Testing Guidelines
+
+### Running Tests
+
+```bash
+# Configure system (Linux)
+sudo modprobe br_netfilter
+sudo sysctl net.bridge.bridge-nf-call-iptables=0
+sudo sysctl net.bridge.bridge-nf-call-ip6tables=0
+
+# Run tests
+cargo test --no-default-features --features=full --verbose
+```
+
+### Test Requirements
+
+- Write tests for new features
+- Maintain existing test coverage
+- Tests should be isolated and repeatable
+- Include both unit and integration tests
+
+## Pull Request Guidelines
+
+1. Target the `develop` branch
+2. Ensure all tests pass
+3. Include clear description and purpose
+4. Reference related issues
+5. Keep changes focused and atomic
+6. Update documentation as needed

+
+### 🚀 Basic Usage
+
+#### Quick Networking with Shared Nodes
+
+EasyTier supports quick networking using shared public nodes. When you don't have a public IP, you can use the free shared nodes provided by the EasyTier community. Nodes will automatically attempt NAT traversal and establish P2P connections. When P2P fails, data will be relayed through shared nodes.
+
+When using shared nodes, each node entering the network needs to provide the same `--network-name` and `--network-secret` parameters as the unique identifier of the network.
+
+Taking two nodes as an example (Please use more complex network name to avoid conflicts):
+
+1. Run on Node A:
+
+```bash
+# Run with administrator privileges
+sudo easytier-core -d --network-name abc --network-secret abc -p tcp://<SharedNodeIP>:11010
+```
+
+2. Run on Node B:
+
+```bash
+# Run with administrator privileges
+sudo easytier-core -d --network-name abc --network-secret abc -p tcp://<SharedNodeIP>:11010
+```
+
+After successful execution, you can check the network status using `easytier-cli`:
+
+```text
+| ipv4         | hostname       | cost  | lat_ms | loss_rate | rx_bytes | tx_bytes | tunnel_proto | nat_type | id         | version         |
+| ------------ | -------------- | ----- | ------ | --------- | -------- | -------- | ------------ | -------- | ---------- | --------------- |
+| 10.126.126.1 | abc-1          | Local | *      | *         | *        | *        | udp          | FullCone | 439804259  | 2.6.2-70e69a38~ |
+| 10.126.126.2 | abc-2          | p2p   | 3.452  | 0         | 17.33 kB | 20.42 kB | udp          | FullCone | 390879727  | 2.6.2-70e69a38~ |
+|              | PublicServer_a | p2p   | 27.796 | 0.000     | 50.01 kB | 67.46 kB | tcp          | Unknown  | 3771642457 | 2.6.2-70e69a38~ |
+```
+
+You can test connectivity between nodes:
+
+```bash
+# Test connectivity
+ping 10.126.126.1
+ping 10.126.126.2
+```
+
+Note: If you cannot ping through, it may be that the firewall is blocking incoming traffic. Please turn off the firewall or add allow rules.
+
+To improve availability, you can connect to multiple shared nodes simultaneously:
+
+```bash
+# Connect to multiple shared nodes
+sudo easytier-core -d --network-name abc --network-secret abc -p tcp://<SharedNodeIP1>:11010 -p udp://<SharedNodeIP2>:11010
+```
+
+Once your network is set up successfully, you can easily configure it to start automatically on system boot. Refer to the [One-Click Register Service guide](https://easytier.cn/en/guide/network/oneclick-install-as-service.html) for step-by-step instructions on registering EasyTier as a system service.
+
+#### Decentralized Networking
+
+EasyTier is fundamentally decentralized, with no distinction between server and client. As long as one device can communicate with any node in the virtual network, it can join the virtual network. Here's how to set up a decentralized network:
+
+1. Start First Node (Node A):
+
+```bash
+# Start the first node
+sudo easytier-core -i 10.144.144.1
+```
+
+After startup, this node will listen on the following ports by default:
+- TCP: 11010
+- UDP: 11010
+- WebSocket: 11011
+- WebSocket SSL: 11012
+- WireGuard: 11013
+
+2. Connect Second Node (Node B):
+
+```bash
+# Connect to the first node using its public IP
+sudo easytier-core -i 10.144.144.2 -p udp://FIRST_NODE_PUBLIC_IP:11010
+```
+
+3. Verify Connection:
+
+```bash
+# Test connectivity
+ping 10.144.144.2
+
+# View connected peers
+easytier-cli peer
+
+# View routing information
+easytier-cli route
+
+# View local node information
+easytier-cli node
+```
+
+For more nodes to join the network, they can connect to any existing node in the network using the `-p` parameter:
+
+```bash
+# Connect to any existing node using its public IP
+sudo easytier-core -i 10.144.144.3 -p udp://ANY_EXISTING_NODE_PUBLIC_IP:11010
+```
+
+### 🔍 Advanced Features
+
+#### Subnet Proxy
+
+Assuming the network topology is as follows, Node B wants to share its accessible subnet 10.1.1.0/24 with other nodes:

 ```mermaid
 flowchart LR

-subgraph Node A IP 22.1.1.1
-nodea[EasyTier\n10.144.144.1]
+subgraph Node A Public IP 22.1.1.1
+nodea[EasyTier<br/>10.144.144.1]
 end

 subgraph Node B
-nodeb[EasyTier\n10.144.144.2]
-end
-
-nodea <-----> nodeb
-
-```
-
-1. Execute on Node A:
-
-    ```sh
-    sudo easytier-core --ipv4 10.144.144.1
-    ```
-
-    Successful execution of the command will print the following.
-
-    ![alt text](/assets/image-2.png)
-
-2. Execute on Node B
-
-    ```sh
-    sudo easytier-core --ipv4 10.144.144.2 --peers udp://22.1.1.1:11010
-    ```
-
-3. Test Connectivity
-
-    The two nodes should connect successfully and be able to communicate within the virtual subnet
-
-    ```sh
-    ping 10.144.144.2
-    ```
-
-    Use easytier-cli to view node information in the subnet
-
-    ```sh
-    easytier-cli peer
-    ```
-
-    ![alt text](/assets/image.png)
-
-    ```sh
-    easytier-cli route
-    ```
-
-    ![alt text](/assets/image-1.png)
-
-
-    ```sh
-    easytier-cli node
-    ```
-
-    ![alt text](assets/image-10.png)
-
---
-
-### Multi-node Networking
-
-Based on the two-node networking example just now, if more nodes need to join the virtual network, you can use the following command.
-
-```sh
-sudo easytier-core --ipv4 10.144.144.2 --peers udp://22.1.1.1:11010
-```
-
-The `--peers` parameter can fill in the listening address of any node already in the virtual network.
-
---
-
-### Subnet Proxy (Point-to-Network) Configuration
-
-Assuming the network topology is as follows, Node B wants to share its accessible subnet 10.1.1.0/24 with other nodes.
-
-```mermaid
-flowchart LR
-
-subgraph Node A IP 22.1.1.1
-nodea[EasyTier\n10.144.144.1]
-end
-
-subgraph Node B
-nodeb[EasyTier\n10.144.144.2]
+nodeb[EasyTier<br/>10.144.144.2]
 end

 id1[[10.1.1.0/24]]

 nodea <--> nodeb <-.-> id1
-
 ```

-Then the startup parameters for Node B's easytier are (new -n parameter)
+To share a subnet, add the `-n` parameter when starting EasyTier:

-```sh
-sudo easytier-core --ipv4 10.144.144.2 -n 10.1.1.0/24
+```bash
+# Share subnet 10.1.1.0/24 with other nodes
+sudo easytier-core -i 10.144.144.2 -n 10.1.1.0/24
 ```

-Subnet proxy information will automatically sync to each node in the virtual network, and each node will automatically configure the corresponding route. Node A can check whether the subnet proxy is effective through the following command.
+Subnet proxy information will automatically sync to each node in the virtual network, and each node will automatically configure the corresponding route. You can verify the subnet proxy setup:

-1. Check whether the routing information has been synchronized, the proxy_cidrs column shows the proxied subnets.
+1. Check if the routing information has been synchronized (the proxy_cidrs column shows the proxied subnets):

-    ```sh
-    easytier-cli route
-    ```
-
-   ![alt text](/assets/image-3.png)
-
-2. Test whether Node A can access nodes under the proxied subnet
-
-    ```sh
-    ping 10.1.1.2
-    ```
-
---
-
-### Networking without Public IP
-
-EasyTier supports networking using shared public nodes. The currently deployed shared public node is ``tcp://public.easytier.cn:11010``.
-
-When using shared nodes, each node entering the network needs to provide the same ``--network-name`` and ``--network-secret`` parameters as the unique identifier of the network.
-
-Taking two nodes as an example, Node A executes:
-
-```sh
-sudo easytier-core -i 10.144.144.1 --network-name abc --network-secret abc -p tcp://public.easytier.cn:11010
+```bash
+# View routing information
+easytier-cli route
 ```

-Node B executes
+![Routing Information](/assets/image-3.png)

-```sh
-sudo easytier-core --ipv4 10.144.144.2 --network-name abc --network-secret abc -p tcp://public.easytier.cn:11010
+2. Test if you can access nodes in the proxied subnet:
+
+```bash
+# Test connectivity to proxied subnet
+ping 10.1.1.2
 ```

-After the command is successfully executed, Node A can access Node B through the virtual IP 10.144.144.2.
+#### WireGuard Integration

-### Use EasyTier with WireGuard Client
-
-EasyTier can be used as a WireGuard server to allow any device with WireGuard client installed to access the EasyTier network. For platforms currently unsupported by EasyTier (such as iOS, Android, etc.), this method can be used to connect to the EasyTier network.
-
-Assuming the network topology is as follows:
+EasyTier can act as a WireGuard server, allowing any device with a WireGuard client (including iOS and Android) to access the EasyTier network. Here's an example setup:

 ```mermaid
 flowchart LR

-ios[[iPhone \n WireGuard Installed]]
+ios[[iPhone<br/>WireGuard Installed]]

-subgraph Node A IP 22.1.1.1
-nodea[EasyTier\n10.144.144.1]
+subgraph Node A Public IP 22.1.1.1
+nodea[EasyTier<br/>10.144.144.1]
 end

 subgraph Node B
-nodeb[EasyTier\n10.144.144.2]
+nodeb[EasyTier<br/>10.144.144.2]
 end

 id1[[10.1.1.0/24]]
@@ -275,86 +249,78 @@ id1[[10.1.1.0/24]]
 ios <-.-> nodea <--> nodeb <-.-> id1
 ```

-To enable an iPhone to access the EasyTier network through Node A, the following configuration can be applied:
+1. Start EasyTier with WireGuard portal enabled:

-Include the --vpn-portal parameter in the easytier-core command on Node A to specify the port that the WireGuard service listens on and the subnet used by the WireGuard network.
-
-```sh
-# The following parameters mean: listen on port 0.0.0.0:11013, and use the 10.14.14.0/24 subnet for WireGuard
-sudo easytier-core --ipv4 10.144.144.1 --vpn-portal wg://0.0.0.0:11013/10.14.14.0/24
+```bash
+# Listen on 0.0.0.0:11013 and use 10.14.14.0/24 subnet for WireGuard clients
+sudo easytier-core -i 10.144.144.1 --vpn-portal wg://0.0.0.0:11013/10.14.14.0/24
 ```

-After successfully starting easytier-core, use easytier-cli to obtain the WireGuard client configuration.
+2. Get WireGuard client configuration:

-```sh
-$> easytier-cli vpn-portal
-portal_name: wireguard
-
-############### client_config_start ###############
-
-[Interface]
-PrivateKey = 9VDvlaIC9XHUvRuE06hD2CEDrtGF+0lDthgr9SZfIho=
-Address = 10.14.14.0/32 # should assign an ip from this cidr manually
-
-[Peer]
-PublicKey = zhrZQg4QdPZs8CajT3r4fmzcNsWpBL9ImQCUsnlXyGM=
-AllowedIPs = 10.144.144.0/24,10.14.14.0/24
-Endpoint = 0.0.0.0:11013 # should be the public ip(or domain) of the vpn server
-PersistentKeepalive = 25
-
-############### client_config_end ###############
-
-connected_clients:
-[]
+```bash
+# Get WireGuard client configuration
+easytier-cli vpn-portal
 ```

-Before using the Client Config, you need to modify the Interface Address and Peer Endpoint to the client's IP and the IP of the EasyTier node, respectively. Import the configuration file into the WireGuard client to access the EasyTier network.
+3. In the output configuration:
+   - Set `Interface.Address` to an available IP from the WireGuard subnet
+   - Set `Peer.Endpoint` to the public IP/domain of your EasyTier node
+   - Import the modified configuration into your WireGuard client

-### Self-Hosted Public Server
+#### Self-Hosted Public Shared Node

-Every virtual network (with same network name and secret) can act as a public server cluster. Nodes of other network can connect to arbitrary nodes in public server cluster to discover each other without public IP.
+You can run your own public shared node to help other nodes discover each other. A public shared node is just a regular EasyTier network (with same network name and secret) that other networks can connect to.

-Run you own public server cluster is exactly same as running an virtual network, except that you can skip config the ipv4 addr.
+To run a public shared node:

-You can also join the official public server cluster with following command:
-
-```
-sudo easytier-core --network-name easytier --network-secret easytier -p tcp://public.easytier.cn:11010
+```bash
+# No need to specify IPv4 address for public shared nodes
+sudo easytier-core --network-name mysharednode --network-secret mysharednode
 ```

+
+### 🚀 基本用法
+
+#### 使用共享节点快速组网
+
+EasyTier 支持使用共享节点快速组网。当您没有公网 IP 时，可以使用公共共享节点。节点会自动尝试 NAT 穿透并建立 P2P 连接。当 P2P 失败时，数据将通过共享节点中继。
+
+使用共享节点时，每个进入网络的节点需要提供相同的 `--network-name` 和 `--network-secret` 参数作为网络的唯一标识符。
+
+以两个节点为例（请使用更复杂的网络名称以避免冲突）：
+
+1. 在节点 A 上运行：
+
+```bash
+# 以管理员权限运行
+sudo easytier-core -d --network-name abc --network-secret abc -p tcp://<共享节点IP>:11010
+```
+
+2. 在节点 B 上运行：
+
+```bash
+# 以管理员权限运行
+sudo easytier-core -d --network-name abc --network-secret abc -p tcp://<共享节点IP>:11010
+```
+
+执行成功后，可以使用 `easytier-cli` 检查网络状态：
+
+```text
+| ipv4         | hostname       | cost  | lat_ms | loss_rate | rx_bytes | tx_bytes | tunnel_proto | nat_type | id         | version         |
+| ------------ | -------------- | ----- | ------ | --------- | -------- | -------- | ------------ | -------- | ---------- | --------------- |
+| 10.126.126.1 | abc-1          | Local | *      | *         | *        | *        | udp          | FullCone | 439804259  | 2.6.2-70e69a38~ |
+| 10.126.126.2 | abc-2          | p2p   | 3.452  | 0         | 17.33 kB | 20.42 kB | udp          | FullCone | 390879727  | 2.6.2-70e69a38~ |
+|              | PublicServer_a | p2p   | 27.796 | 0.000     | 50.01 kB | 67.46 kB | tcp          | Unknown  | 3771642457 | 2.6.2-70e69a38~ |
+```
+
+您可以测试节点之间的连通性：
+
+```bash
+# 测试连通性
+ping 10.126.126.1
+ping 10.126.126.2
+```
+
+注意：如果无法 ping 通，可能是防火墙阻止了入站流量。请关闭防火墙或添加允许规则。
+
+为了提高可用性，您可以同时连接多个共享节点：
+
+```bash
+# 连接多个共享节点
+sudo easytier-core -d --network-name abc --network-secret abc -p tcp://<公共节点IP>:11010 -p udp://<公共节点IP>:11010
+```
+
+#### 去中心化组网
+
+EasyTier 本质上是去中心化的，没有服务器和客户端的区分。只要一个设备能与虚拟网络中的任何节点通信，它就可以加入虚拟网络。以下是如何设置去中心化网络：
+
+1. 启动第一个节点（节点 A）：
+
+```bash
+# 启动第一个节点
+sudo easytier-core -i 10.144.144.1
+```
+
+启动后，该节点将默认监听以下端口：
+- TCP：11010
+- UDP：11010
+- WebSocket：11011
+- WebSocket SSL：11012
+- WireGuard：11013
+
+2. 连接第二个节点（节点 B）：
+
+```bash
+# 使用第一个节点的公网 IP 连接
+sudo easytier-core -i 10.144.144.2 -p udp://第一个节点的公网IP:11010
+```
+
+3. 验证连接：
+
+```bash
+# 测试连通性
+ping 10.144.144.2
+
+# 查看已连接的对等节点
+easytier-cli peer
+
+# 查看路由信息
+easytier-cli route
+
+# 查看本地节点信息
+easytier-cli node
+```
+
+更多节点要加入网络，可以使用 `-p` 参数连接到网络中的任何现有节点：
+
+```bash
+# 使用任何现有节点的公网 IP 连接
+sudo easytier-core -i 10.144.144.3 -p udp://任何现有节点的公网IP:11010
+```
+
+### 🔍 高级功能
+
+#### 子网代理
+
+假设网络拓扑如下，节点 B 想要与其他节点共享其可访问的子网 10.1.1.0/24：

 ```mermaid
 flowchart LR

-subgraph 节点 A IP 22.1.1.1
-nodea[EasyTier\n10.144.144.1]
+subgraph 节点 A 公网 IP 22.1.1.1
+nodea[EasyTier<br/>10.144.144.1]
 end

 subgraph 节点 B
-nodeb[EasyTier\n10.144.144.2]
-end
-
-nodea <-----> nodeb
-
-```
-
-1. 在节点 A 上执行：
-
-    ```sh
-    sudo easytier-core --ipv4 10.144.144.1
-    ```
-
-    命令执行成功会有如下打印。
-
-    ![alt text](/assets/image-2.png)
-
-2. 在节点 B 执行
-
-    ```sh
-    sudo easytier-core --ipv4 10.144.144.2 --peers udp://22.1.1.1:11010
-    ```
-
-3. 测试联通性
-
-    两个节点应成功连接并能够在虚拟子网内通信
-
-    ```sh
-    ping 10.144.144.2
-    ```
-
-    使用 easytier-cli 查看子网中的节点信息
-
-    ```sh
-    easytier-cli peer
-    ```
-
-    ![alt text](/assets/image.png)
-
-    ```sh
-    easytier-cli route
-    ```
-
-    ![alt text](/assets/image-1.png)
-
-    ```sh
-    easytier-cli node
-    ```
-
-    ![alt text](assets/image-10.png)
-
---
-
-### 多节点组网
-
-基于刚才的双节点组网例子，如果有更多的节点需要加入虚拟网络，可以使用如下命令。
-
-```sh
-sudo easytier-core --ipv4 10.144.144.2 --peers udp://22.1.1.1:11010
-```
-
-其中 `--peers` 参数可以填写任意一个已经在虚拟网络中的节点的监听地址。
-
---
-
-### 子网代理（点对网）配置
-
-假设网络拓扑如下，节点 B 想将其可访问的子网 10.1.1.0/24 共享给其他节点。
-
-```mermaid
-flowchart LR
-
-subgraph 节点 A IP 22.1.1.1
-nodea[EasyTier\n10.144.144.1]
-end
-
-subgraph 节点 B
-nodeb[EasyTier\n10.144.144.2]
+nodeb[EasyTier<br/>10.144.144.2]
 end

 id1[[10.1.1.0/24]]

 nodea <--> nodeb <-.-> id1
-
 ```

-则节点 B 的 easytier 启动参数为（新增 -n 参数）
+要共享子网，在启动 EasyTier 时添加 `-n` 参数：

-```sh
-sudo easytier-core --ipv4 10.144.144.2 -n 10.1.1.0/24
+```bash
+# 与其他节点共享子网 10.1.1.0/24
+sudo easytier-core -i 10.144.144.2 -n 10.1.1.0/24
 ```

-子网代理信息会自动同步到虚拟网络的每个节点，各个节点会自动配置相应的路由，节点 A 可以通过如下命令检查子网代理是否生效。
+子网代理信息将自动同步到虚拟网络中的每个节点，每个节点将自动配置相应的路由。您可以验证子网代理设置：

-1. 检查路由信息是否已经同步，proxy_cidrs 列展示了被代理的子网。
+1. 检查路由信息是否已同步（proxy_cidrs 列显示代理的子网）：

-    ```sh
-    easytier-cli route
-    ```
-
-    ![alt text](/assets/image-3.png)
-
-2. 测试节点 A 是否可访问被代理子网下的节点
-
-    ```sh
-    ping 10.1.1.2
-    ```
-
---
-
-### 无公网IP组网
-
-EasyTier 支持共享公网节点进行组网。目前已部署共享的公网节点 ``tcp://public.easytier.cn:11010``。
-
-使用共享节点时，需要每个入网节点提供相同的 ``--network-name`` 和 ``--network-secret`` 参数，作为网络的唯一标识。
-
-以双节点为例，节点 A 执行：
-
-```sh
-sudo easytier-core -i 10.144.144.1 --network-name abc --network-secret abc -p tcp://public.easytier.cn:11010
+```bash
+# 查看路由信息
+easytier-cli route
 ```

-节点 B 执行
+![路由信息](/assets/image-3.png)

-```sh
-sudo easytier-core --ipv4 10.144.144.2 --network-name abc --network-secret abc -p tcp://public.easytier.cn:11010
+2. 测试是否可以访问代理子网中的节点：
+
+```bash
+# 测试到代理子网的连通性

-EasyTier 可以用作 WireGuard 服务端，让任意安装了 WireGuard 客户端的设备访问 EasyTier 网络。对于目前 EasyTier 不支持的平台 （如 iOS、Android 等），可以使用这种方式接入 EasyTier 网络。
-
-假设网络拓扑如下：
+EasyTier 可以作为 WireGuard 服务器，允许任何安装了 WireGuard 客户端的设备（包括 iOS 和 Android）访问 EasyTier 网络。以下是设置示例：

-我们需要 iPhone 通过节点 A 访问 EasyTier 网络，则可进行如下配置：
+1. 启动启用 WireGuard 门户的 EasyTier：

-在节点 A 的 easytier-core 命令中，加入 --vpn-portal 参数，指定 WireGuard 服务监听的端口，以及 WireGuard 网络使用的网段。
-
-```sh
-# 以下参数的含义为： 监听 0.0.0.0:11013 端口，WireGuard 使用 10.14.14.0/24 网段
-sudo easytier-core --ipv4 10.144.144.1 --vpn-portal wg://0.0.0.0:11013/10.14.14.0/24
+```bash
+# 在 0.0.0.0:11013 上监听，并使用 10.14.14.0/24 子网作为 WireGuard 客户端
+sudo easytier-core -i 10.144.144.1 --vpn-portal wg://0.0.0.0:11013/10.14.14.0/24
 ```

-easytier-core 启动成功后，使用 easytier-cli 获取 WireGuard Client 的配置。
+2. 获取 WireGuard 客户端配置：

-```sh
-$> easytier-cli vpn-portal
-portal_name: wireguard
-
-############### client_config_start ###############
-
-[Interface]
-PrivateKey = 9VDvlaIC9XHUvRuE06hD2CEDrtGF+0lDthgr9SZfIho=

-
-[Peer]
-PublicKey = zhrZQg4QdPZs8CajT3r4fmzcNsWpBL9ImQCUsnlXyGM=
-AllowedIPs = 10.144.144.0/24,10.14.14.0/24
-Endpoint = 0.0.0.0:11013 # should be the public ip(or domain) of the vpn server
-PersistentKeepalive = 25
-
-############### client_config_end ###############
-

+```bash
+# 获取 WireGuard 客户端配置
+easytier-cli vpn-portal
 ```

-使用 Client Config 前，需要将 Interface Address 和 Peer Endpoint 分别修改为客户端的 IP 和 EasyTier 节点的 IP。将配置文件导入 WireGuard 客户端，即可访问 EasyTier 网络。
+3. 在输出配置中：
+   - 将 `Interface.Address` 设置为 WireGuard 子网中的可用 IP
+   - 将 `Peer.Endpoint` 设置为您的 EasyTier 节点的公网 IP/域名
+   - 将修改后的配置导入到您的 WireGuard 客户端

+#### 自建公共共享节点

-### 自建公共中转服务器
+您可以运行自己的公共共享节点来帮助其他节点相互发现。公共共享节点只是一个普通的 EasyTier 网络（具有相同的网络名称和密钥），其他网络可以连接到它。

-每个虚拟网络（通过相同的网络名称和密钥建链）都可以充当公共服务器集群。其他网络的节点可以连接到公共服务器集群中的任意节点，无需公共 IP 即可发现彼此。
+要运行公共共享节点：

-运行自建的公共服务器集群与运行虚拟网络完全相同，不过可以跳过配置 ipv4 地址。
-
-也可以使用以下命令加入官方公共服务器集群，后续将实现公共服务器集群的节点间负载均衡：
-
-```
-sudo easytier-core --network-name easytier --network-secret easytier -p tcp://public.easytier.cn:11010
+```bash
+# 公共共享节点无需指定 IPv4 地址
+sudo easytier-core --network-name mysharednode --network-secret mysharednode
 ```

-### 其他配置
+网络设置成功后，您可以轻松配置它以在系统启动时自动启动。请参阅 [一键注册服务指南](https://easytier.cn/en/guide/network/oneclick-install-as-service.html) 了解如何将 EasyTier 注册为系统服务。

+# EasyTier Core Architecture
+
+## Status and scope
+
+This document describes the current architecture after the portable-core
+refactor. It is the source of truth for ownership, dependency direction,
+feature boundaries, and validation. It intentionally records the resulting
+design rather than the migration history.
+
+The refactor has three principal crate roles:
+
+- `easytier-core` owns portable EasyTier configuration, protocol state,
+  routing, peer state, connectivity orchestration, packet processing, and
+  instance lifecycle.
+- `easytier` is the native composition root. It owns operating-system
+  resources, native protocol engines, process integration, CLI and native
+  presentation.
+- `easytier-proto` owns generated protobuf and RPC types, descriptor data, and
+  the feature slices needed by core and presentation users.
+
+`easytier-core` is designed to compile without direct operating-system network
+access. It supports native hosts through Rust traits and has a target-only WASI
+adapter and ABI implementation under `easytier-core/src/wasi`.
+
+This architecture does not require compatibility with old internal module
+paths. Wire compatibility, configuration compatibility, management semantics,
+and externally used application behaviour remain compatibility requirements.
+
+## Architectural vocabulary
+
+The following terms have specific meanings in this document:
+
+- **Module**: an interface and the implementation hidden behind it.
+- **Host**: the process or runtime embedding core and owning platform
+  resources.
+- **Host capability**: an operation core may request but must not implement
+  with direct OS calls.
+- **Adapter**: a concrete implementation of a Host capability or protocol
+  extension.
+- **Composition root**: code that creates core configuration, Host Adapters,
+  instances, and process-level services.
+- **Runtime configuration**: the authoritative normalized state used after an
+  instance starts.
+- **Packet plane**: portable packet classification, routing, transformation,
+  proxy/NAT state, and forwarding decisions.
+
+New abstractions should pass a deletion test: deleting a useful deep Module
+should force non-trivial policy or lifecycle logic to reappear in multiple
+callers. A pass-through wrapper with no independent invariant is not an
+architectural boundary.
+
+## Crate dependency direction
+
+The principal dependency direction is:
+
+```text
+easytier-proto <- easytier-core <- easytier
+```
+
+Presentation crates and platform integrations consume these crates. Portable
+policy must not move outward merely because one current consumer is native.
+Conversely, core must not absorb an OS mechanism or a protocol engine whose
+dependencies cannot satisfy the core target contract.
+
+### `easytier-proto`
+
+The protobuf crate is split by public Cargo features:
+
+- `core` provides the common wire messages, peer RPC messages, generated RPC
+  runtime, and descriptor bytes needed by core.
+- `api` adds management API messages.
+- protocol-specific features add only their generated message modules.
+- `json-rpc` enables the well-known protobuf JSON types used by the management
+  plane.
+- `full` is the compatibility aggregate used by complete products.
+
+The core crate depends on `easytier-proto` with default features disabled and
+enables only `core`, adding API or JSON-RPC types through its own management
+features.
+
+The main core/native path has no `prost-reflect` dependency. OSPF route
+reflection uses the focused wire editor in
+`peers/route/route_peer_wire.rs`. It retains the original encoded
+`RoutePeerInfo`, replaces only the fields credential filtering is allowed to
+change, and leaves all other top-level and nested fields intact. This is
+required so unknown fields survive mixed-version, multi-hop propagation.
+Generated Rust types remain responsible for normal message construction and
+validation.
+
+Descriptor sets are still generated and embedded by `easytier-proto`; removing
+runtime reflection did not remove descriptor data used by configuration and
+RPC tooling. The OHOS integration has its own schema service and dependency
+policy and is outside this replacement.
+
+### `easytier-core`
+
+Core owns portable behaviour and exposes capability seams. Its normal
+dependencies use Tokio runtime, time, synchronization, and I/O traits without
+requiring the full Tokio feature set.
+
+Core may depend on optional portable engines when their owning feature is
+enabled. It does not create real native TCP/UDP sockets, alter routes, open a
+TUN device, enter a network namespace, configure system DNS, manage a service,
+or invoke UPnP/NAT-PMP directly.
+
+### `easytier`
+
+The native crate owns:
+
+- process startup, shutdown, signals, service management, and allocators;
+- filesystem configuration input and persistence;
+- real TCP/UDP, DNS, TUN, raw-socket, route, interface, namespace, and socket
+  option operations;
+- UPnP and NAT-PMP operations;
+- Unix and FakeTCP resources;
+- WebSocket/WSS, QUIC, WireGuard, and KCP concrete engines;
+- native Magic DNS serving and system DNS integration;
+- CLI, web, GUI, FFI, and native management presentation.
+
+Native code may translate values and assemble Adapters. It must not maintain a
+second peer graph, reproduce core routing or hole-punch policy, or invent an
+alternative instance lifecycle.
+
+## Internal core layers
+
+The physical module layout follows this downward order:
+
+```text
+foundation
+  <- config / packet
+  <- socket
+  <- host
+  <- tunnel
+  <- listener / connectivity
+  <- peers / rpc
+  <- gateway
+  <- instance
+  <- management
+```
+
+`process_runtime` is a process- or module-scoped owner shared by instances.
+`wasi` is target integration and is compiled only for tests or the WASI target;
+it is not an additional portable domain layer.
+
+### Foundation
+
+`foundation/` contains task supervision, the time facade, rate limiting,
+statistics primitives, and the domain-neutral external operation broker. The
+broker owns asynchronous operation lifecycle and completion storage while the
+calling domain owns operation kinds, outcomes, resources, and errors.
+Foundation must not depend on a domain layer.
+
+### Configuration and packets
+
+`config/` owns:
+
+- the complete `TomlConfig` model;
+- parsing, serialization, and validation;
+- OS-independent defaults;
+- peer, encryption, gateway, and API input models;
+- normalized runtime snapshots and the live runtime configuration store.
+
+The Host supplies platform facts through `CoreInstanceHostConfig`. Core applies
+the policy that combines those facts with TOML input. This is especially
+important for a WASI build: the compile-time guest target cannot be used as a
+proxy for the Host operating system.
+
+`packet/` owns EasyTier packet structures, compression, STUN and hole-punch
+wire codecs. It does not own socket I/O or connection policy.
+
+### Socket and Host seams
+
+`socket/` contains transport-neutral primitives:
+
+- `SocketContext`, including IP-family policy, optional socket mark, and an
+  opaque network-namespace token;
+- virtual TCP socket, listener, and factory traits;
+- virtual UDP socket and factory traits;
+- UDP session multiplexing, classification, and lifecycle;
+- in-process Ring sockets.
+
+`host/` is the single home of Host capability seams:
+
+- DNS and DNS record resolution;
+- connector environment observations;
+- packet ingress and egress;
+- Host socket operation bridges and handle-based TCP/UDP/listener adapters.
+
+Core owns scheduling, backpressure, cancellation, UDP session state, and
+protocol state even when each actual operation crosses a Host Adapter. A Host
+Adapter owns the real resource and performs the OS operation.
+
+The native `NativeHostRuntime` is process-wide and does not retain an instance
+`GlobalCtx`, namespace guard, socket mark, or connectivity state. Differences
+between instances travel in each request's `SocketContext`. A narrow
+instance-host projection may expose listener and interface facts, but it does
+not become another socket factory.
+
+### Tunnel and listener
+
+A socket is a raw communication endpoint. A Tunnel is an EasyTier connection
+created by adding framing, metadata, handshakes, and protocol lifecycle.
+
+Core owns:
+
+- raw TCP framing and upgrade;
+- UDP tunnel/session framing and classification;
+- Ring Tunnel identity and registry state;
+- encryption and secure-datagram policy that is portable;
+- client/server protocol selection interfaces;
+- listener planning, optional/required listener policy, retry, accept
+  scheduling, running-listener registry, and orderly shutdown.
+
+Native protocol Adapters own WebSocket/WSS, QUIC, WireGuard, and KCP engines.
+Unix and FakeTCP are socket resources that feed a core protocol upgrader; they
+are not independent owners of EasyTier peer state.
+
+Each protocol registration must provide a coherent client/server Adapter.
+Unavailable configured transports must be rejected during validation or
+protocol selection in the standard runtime, rather than silently falling back
+to another transport. A compact compatibility Host may instead retain the
+desired value for management readback and omit it from normalized runtime
+state; it must not advertise or partially activate the unavailable transport.
+
+### Connectivity
+
+`connectivity/` owns:
+
+- manual connection and endpoint discovery policy;
+- direct candidate selection;
+- retry, backoff, blacklists, and listener reuse;
+- STUN requests, responses, probing, NAT inference, and published endpoint
+  state;
+- TCP and UDP hole-punch state machines;
+- UDP port-mapping policy and lease lifecycle;
+- conversion of successful sockets into protocol-upgrade requests.
+
+The Host owns DNS execution, socket syscalls, interface enumeration, bind
+device/mark/namespace operations, and concrete UPnP/NAT-PMP calls. STUN-only
+hole punching remains available when the Host does not supply a port-mapping
+Adapter.
+
+Some connectivity files intentionally implement peer-facing adapter traits for
+`PeerManagerCore`. These are localized integration edges between adjacent
+domains, not permission for lower socket or Host layers to depend on peers.
+
+### Peers and RPC
+
+`peers/` is the authoritative owner of:
+
+- admission and connection sessions;
+- peer maps and connection lifecycle;
+- ACL and whitelist decisions;
+- OSPF route calculation and graph algorithms;
+- peer and credential RPC registration;
+- foreign-network admission, identity, relay, and lifecycle;
+- peer-center state and public IPv6 policy;
+- traffic metrics and peer snapshots.
+
+Submodules progress from kernel types and utilities, through ACL/context,
+connection state, route state, manager services, and finally foreign-network
+and peer-center composition. Callers consume the public surface declared by
+the domain rather than reaching into a parallel native peer owner.
+
+`rpc/` owns the peer-flavoured RPC transport, packet fragmentation, client and
+server lifecycle, handler registry, and standalone listener/client lifecycle.
+Generated service descriptors and message types remain in `easytier-proto`.
+
+### Gateway
+
+`gateway/` owns portable packet-plane features:
+
+- proxy CIDR state and monitoring policy;
+- packet parsing, reassembly, NAT/proxy state, and TCP/UDP/ICMP decisions;
+- the smoltcp-backed portable dataplane selected by its feature;
+- SOCKS5 framing, authentication, association, routing, and session state;
+- wrapped-transport planning and session state used by KCP and QUIC Adapters;
+- DHCP allocation policy;
+- Magic DNS route and response policy;
+- VPN portal client/session policy;
+- UDP broadcast classification and rewrite policy.
+
+TUN, raw sockets, transparent-destination lookup, concrete protocol engines,
+native DNS servers, namespace operations, and route application stay in native
+Adapters.
+
+Optional gateway capabilities are selected by cohesive Modules. Disabled
+implementations retain stable lifecycle calls and report unsupported
+configuration in the standard runtime. A compact compatibility Host may
+silently normalize those settings to no-ops while preserving the desired TOML
+model; disabled implementations do not duplicate portable policy.
+
+The instance-scoped `DataPlaneSession` composes the foundation operation broker
+under the same session lock as its resource and quota state. The broker owns
+generic completion, cancellation, free, drain, and take transitions. The data
+plane retains TCP/UDP resource ownership, operation metadata, route deadlines,
+and error semantics.
+
+The proposed restructuring of the smoltcp data plane, SOCKS5 and port-forward
+Adapters, portable KCP engine, event-driven FFI/WASI completion model, and Go
+Host integration is tracked in
+[`data-plane-runtime-plan.md`](data-plane-runtime-plan.md). That document is a
+future implementation plan; this document remains the source of truth for the
+currently implemented architecture until the plan is completed.
+
+### Instance and management
+
+`CoreInstance::new(CoreInstanceConfig, CoreHostAdapters)` is the sole direct
+construction path for a normalized instance. `CoreInstance::from_toml` uses
+the same normalization and construction path. Core constructs the peer graph,
+runtime store, STUN collector, connectivity managers, listener runtime, packet
+plane, gateway runtimes, and lifecycle owners.
+
+A core instance:
+
+- owns all mutable portable state for one network;
+- is one-shot after `stop`;
+- exposes one complete `start` and one `stop` lifecycle interface;
+- starts Modules in a fixed serial composition order without cross-Module
+  started flags or staged activation;
+- installs initial ACL, proxy CIDR, and manual-peer inputs before startup;
+- serializes lifecycle operations with one instance-level operation lock;
+- owns cooperative cancellation and component shutdown order;
+- exposes `CorePacketPlane` as the narrow packet/route projection used by Host
+  dataplane Adapters;
+- treats its normalized runtime store as authoritative after construction.
+
+`CoreHostAdapters` contains the required Host, DNS, packet sink, and
+`CoreProcessRuntime`, plus optional protocol and platform capabilities. The
+bundle carries capabilities, not preconstructed portable managers.
+
+Each Module owns partial-start cleanup for its internal resources.
+`CoreInstance` has one outer cancellation and recovery path for the complete
+serial startup. `Running` therefore means the Host runtime and every enabled
+portable Module have started successfully; there is no separate post-Host
+activation state. Host packet tasks stop before PeerManager resources are
+cleared.
+
+`InstanceManager<F>` is the canonical UUID-indexed instance collection for one
+Host composition. Its `InstanceFactory` constructs one complete record before
+the manager performs an atomic uniqueness check. The manager owns collection
+membership; it does not own startup order, persistence, daemon policy, cached
+errors, ABI handles, or RPC projections.
+
+`management/` consumes the canonical manager and instances. It owns:
+
+- stable UUID/name selection;
+- read-only instance and peer management RPC;
+- full process mutation and configuration transactions when enabled;
+- persistence and logger-control capability interfaces;
+- management listener/client lifecycle and JSON-RPC presentation.
+
+There is one process-level management entry. Instances and the manager do not
+depend on management response projections.
+
+## Process-scoped state
+
+`CoreProcessRuntime` owns portable resources shared across instances in one
+process or instantiated module:
+
+- the Ring Tunnel registry and namespace;
+- a reference-counted protected TCP-port registry.
+
+The composition root creates and shares one runtime. Management listener ports
+are protected before bind and held by leases after the concrete port is known.
+Native and target adapters supply bound resources but do not implement a
+second protected-port registry.
+
+Process-global capability objects may contain stateless or shared platform
+mechanisms. They must not contain instance-specific peer, route,
+configuration, or connectivity state.
+
+## Runtime configuration authority
+
+`TomlConfig` is the authoritative desired configuration used for management
+readback and patch transactions. Compact Hosts keep unsupported accepted values
+there so controllers observe the configuration they submitted.
+
+The separately typed, normalized core runtime store is authoritative for live
+behavior:
+
+- peer feature flags and routing policy;
+- listeners and initial peers;
+- ACL and whitelist inputs;
+- manual and VPN portal CIDRs;
+- gateway and connectivity settings;
+- runtime configuration patches.
+
+Host persistence is an effect following a successful core transaction. A Host
+Adapter must not call back into an instance to obtain a hidden configuration
+snapshot while core is applying an operation.
+
+Non-serializable resources such as TUN descriptors, packet sinks, execution
+domains, and native protocol engines are construction context, not TOML
+fields.
+
+## Logging
+
+The main native runtime uses a small logger implemented in
+`easytier/src/common/log`:
+
+- `log` records and `tracing` events share console and file sinks;
+- timestamps, compact formatting, optional terminal colours, `NO_COLOR`, and
+  basic `RUST_LOG` target/level filters are implemented directly;
+- file rotation uses the existing EasyTier rolling appender;
+- management RPC can reload the file level;
+- an atomic maximum-level gate rejects disabled events before target matching
+  or file-filter locking;
+- concurrent file-level reload serializes the filter and atomic-level update.
+
+File logging and no-file logging are separate selected backends. The default
+tracing backend records events and deliberately ignores span trees. The
+optional `tracing` feature selects the tokio-console subscriber integration;
+only that diagnostic profile pulls the main crate's `tracing-subscriber` and
+`console-subscriber` dependencies.
+
+Contrib applications and platform integrations may have independent logging
+requirements and are not implicitly wired to the native process logger.
+
+## Feature model
+
+Features represent coherent capabilities, not arbitrary source fragments.
+Important core feature relationships are:
+
+- `management-rpc` enables generated management API types and read-only
+  management services.
+- `management` adds configuration writes, full management composition, rich
+  errors, and JSON-RPC.
+- `proxy-packet` enables portable packet parsing/proxy machinery and the
+  required smoltcp packet features.
+- `proxy-smoltcp-stack` adds the async TCP/UDP smoltcp stack.
+- `dns-resolver` is the shared Hickory resolver leaf used by endpoint
+  discovery and Magic DNS without coupling either capability to the other.
+- `endpoint-discovery` adds HTTPS endpoint discovery dependencies.
+- `magic-dns` enables its DNS server, management wire messages, and portable
+  packet-query integration.
+- `tcp-hole-punch` enables the TCP hole-punch runtime.
+- `dhcp-ipv4`, `public-ipv6-provider`, `vpn-portal`,
+  `wrapped-transport`, and `proxy-cidr-monitor` are independent gateway or
+  platform-policy leaves.
+- `extended-services` is the compatibility aggregate for those leaves.
+- encryption and compression engines remain independently selectable.
+
+The native crate maps product features to the core and protocol features it
+actually consumes. A protocol feature must not accidentally enable unrelated
+gateway or management capabilities.
+
+Production feature and platform selection belongs at Module or Adapter
+boundaries rather than inside shared implementations. The logger demonstrates
+the intended pattern: file and tracing variants are complete backend modules
+with one stable interface, so shared event processing contains no feature
+branches.
+
+## Module boundaries
+
+The dependency directions in this document define the intended module
+boundaries. Changes that require a new upward edge must first define a stable
+lower-layer interface or explicitly revise this architecture.
+
+Modules are `pub(crate)` by default. Each domain's `mod.rs` declares its
+outward surface. Public visibility is used for real cross-crate Host,
+configuration, management, packet-plane, or test-support interfaces.
+
+## Architectural invariants
+
+1. Portable EasyTier policy has one owner in `easytier-core`.
+2. Core does not perform real OS socket, DNS, TUN, route, filesystem
+   configuration, process, or service-manager operations.
+3. Host-OS policy is runtime input; a WASI compile target is not Host policy.
+4. Every real socket and DNS operation crosses a Host capability seam.
+5. Core owns socket scheduling, backpressure, protocol state, and cancellation.
+6. Dial, accept, and hole-punch paths produce sockets before protocol upgrade.
+7. Peer admission consumes upgraded transports and does not create OS
+   resources.
+8. Each instance owns its mutable peer, route, connectivity, gateway, and
+   runtime configuration state.
+9. One Host composition has one canonical UUID-to-instance manager.
+10. Process-level runtimes do not capture instance state.
+11. `CoreInstance::new` is the sole normalized direct construction entry.
+12. The manager owns membership, not lifecycle or presentation.
+13. Management consumes the manager; the manager does not return management
+    projections.
+14. Unknown protobuf fields in reflected route information survive forwarding
+    and credential filtering.
+15. Feature selection is localized at cohesive Module/Adapter boundaries.
+16. The standard runtime rejects unsupported configured capabilities. Compact
+    compatibility Hosts may preserve them as runtime no-ops, but never change
+    wire protocol, advertise them, or silently fall back to an unsafe mode.
+
+## Validation
+
+Changes to these boundaries should run, at minimum:
+
+```text
+cargo fmt --all -- --check
+cargo check -p easytier-core -p easytier-proto -p easytier --features full
+cargo test -p easytier-core --lib
+```
+
+Feature work should add focused checks for the changed no-default, isolated,
+default, full, and cross-target profiles. Socket, TUN, namespace, protocol
+engine, and multi-node changes require the relevant Docker integration tests.
+WASI ABI or Adapter changes require a `wasm32-wasip1` build and target-side
+tests. These compiler-resolved profiles are the authority for feature and
+target boundaries.
+
+CI path filters include `easytier-core`, `easytier-proto`, native, web, GUI
+Tauri, and contrib. The archived Rust test suite contains both `easytier` and
+`easytier-core`.
+
+## Known limitations and debt
+
+- Some production feature and platform gates still select fields or statements
+  inside shared implementations. New code should prefer complete Module or
+  Adapter variants, and existing cases should move only when their owning
+  Module is changed.
+- Connectivity retains localized Adapter implementations that name
+  `PeerManagerCore`; further decoupling requires an interface extraction, not
+  a visibility-only move.
+- Native Linux namespace guards exist in paths that can cross async suspension.
+  Because `setns` is thread-local, those operations should eventually be kept
+  on one non-migrating execution context.
+- QUIC session retirement after failed or exhausted accepted sessions remains
+  separate native-engine correctness work; it must preserve multiple
+  connections sharing one QUIC endpoint/session.
+
+These limitations are not reasons to add fallback owners or parallel state.
+Fixes should preserve the ownership rules above and address the responsible
+Module directly.

+# HarmonyOS HAR delivery
+
+The `ohos` workflow builds the Core HAR on pushes, pull requests, tags, and
+manual runs. Every successful run retains a short-lived HAR artifact, while
+publication to the private OHPM registry is deliberately restricted:
+
+- A push to `main` publishes only when the pushed SHA is the merge commit of a
+  pull request targeting `main` and the push is not forced.
+- A manual run on `main` publishes by default.
+- A manual run on another branch publishes only when its `publish` input is
+  enabled.
+- Direct pushes, pull requests, tags, and ordinary non-main branch builds do
+  not publish.
+
+## Package identity
+
+All branches publish the same private package name, `easytier-ohrs`. The
+source branch is encoded in the package version instead of the package name:
+
+```text
+<core-version>-<branch-id>-<commits-since-tag>-<run-number>-<run-attempt>-g<short-sha>
+```
+
+`branch-id` is a lowercase, OHPM-safe form of the source branch. Publishing a
+new version advances the registry's `latest` version. After publication, Core
+sends the `core-har-published` repository dispatch to the ArkTS and Pro
+repositories. The payload contains only `core_repository`, `core_ref`, and
+`package_name`.
+
+## App install sequence
+
+ArkTS and Pro use the same three OHPM commands:
+
+```bash
+ohpm uninstall "$CORE_HAR_PACKAGE"
+ohpm install "$CORE_HAR_PACKAGE@latest" \
+  --registry "$CORE_HAR_REGISTRY"
+ohpm install
+```
+
+The App workflow then reads the installed version from:
+
+```text
+oh_modules/<package_name>/oh-package.json5
+```
+
+The existing `oh-package-lock.json5` and `oh_modules` directory are not
+manually deleted. Because the package name remains `easytier-ohrs`, downstream
+source imports do not need to be rewritten.
+
+## Secrets
+
+Core requires:
+
+- `CODEARTS_PRIVATE_OHPM`: publish-capable OHPM configuration.
+- `DOWNSTREAM_DISPATCH_TOKEN`: permission to dispatch both App repositories.
+
+ArkTS and Pro require:
+
+- `CODEARTS_PRIVATE_OHPM_READ`: read-only private OHPM authentication.
+- `SIGNING_REPOSITORY_TOKEN`: read access to the corresponding private signing
+  repository.
+
+Signing and AppGallery Connect credentials remain downstream application
+concerns and are not passed through the Core dispatch payload.

+# QUIC TCP Proxy 内存对比（2026-07-27）
+
+## 结论
+
+在相同的双节点 network namespace 环境中，当前分支相对 2.6.4：
+
+- 空闲且未建立 TCP proxy 连接时，两端合计 USS 从 15.95 MiB
+  降至 11.66 MiB，下降 26.9%；
+- 66 条空闲 TCP proxy 连接时，两端合计 USS 从 19.45 MiB
+  降至 13.85 MiB，下降 28.8%；
+- 固定 1 Gbit/s 的单流 TCP proxy 传输中，两端平均 USS 从
+  20.69 MiB 降至 14.75 MiB，下降 28.7%，同步峰值从
+  21.50 MiB 降至 15.02 MiB；
+- 从 0 增长到 66 条空闲连接推算，每条连接在两个 core 上合计
+  增加约 33.9 KiB USS；2.6.4 为 54.2 KiB，下降 37.4%；
+- 当前分支的匿名内存下降约 40% 至 44%，说明堆和连接缓冲区开销
+  确实降低。
+
+当前分支的 RSS 比 2.6.4 高约 5% 至 11%，但这部分差异没有出现在
+Anonymous 中，主要体现为非匿名或共享驻留页。PSS 在高连接数及
+固定吞吐场景基本持平，USS 和 Anonymous 则显著更低。因此不能
+只根据 RSS 判断发生了内存回退。
+
+## 测试对象
+
+| 版本 | 标识 | 二进制 |
+|---|---|---|
+| 当前分支 | commit `9e2ed33aeb37`，版本 `2.6.4-9e2ed33a` | `target/x86_64-unknown-linux-musl/release/easytier-core` |
+| 2.6.4 | 版本 `2.6.4-8428a89d` | `/data/tickets/easytier/easytier-linux-x86_64/easytier-core` |
+
+当前分支使用以下命令重新构建，确保被测二进制准确对应 HEAD：
+
+```console
+cargo build --release \
+  --target x86_64-unknown-linux-musl \
+  -p easytier \
+  --features jemalloc \
+  --bin easytier-core \
+  --bin easytier-cli
+```
+
+两个二进制均为 stripped static PIE。当前分支明确使用 musl 和
+jemalloc。
+
+## 测试拓扑
+
+- 两个 `easytier-core` 分别运行在独立的 network namespace；
+- namespace 通过 Linux bridge 和 veth 连接；
+- underlay 地址为 `10.251.89.10/24` 和 `10.251.89.11/24`；
+- EasyTier 虚拟地址为 `10.144.144.1/24` 和
+  `10.144.144.2/24`；
+- 两个节点之间使用 UDP listener 建立 EasyTier peer 连接；
+- 源节点启用 `--enable-quic-proxy true`；
+- 两个节点均保留默认 QUIC input；
+- TCP client 从 `10.144.144.1` 访问绑定在
+  `10.144.144.2` 上的 server；
+- `tcp_proxy_connect` 指标的 `protocol` 标签确认为 `QUIC`；
+- 66 条连接场景通过两端各 132 个 established TCP socket 条目
+  确认当前连接数。
+
+## 采样口径
+
+数据读取自 `/proc/<pid>/smaps_rollup`：
+
+- RSS：进程映射的全部驻留页，包含共享代码页；
+- PSS：共享页按共享进程数量分摊后的驻留内存；
+- USS：`Private_Clean + Private_Dirty`，表示进程独占内存；
+- Anonymous：匿名页，主要反映堆、栈和运行时缓冲区。
+
+空闲场景每隔 2 秒采样一次，共 5 次，表格记录均值。固定吞吐场景
+持续 20 秒，每隔 2 秒采样一次，共 8 次，同时记录均值和峰值。
+所有容量单位均为 MiB。
+
+## 空闲连接结果
+
+以下数据均为两个 EasyTier core 的合计值：
+
+| 当前连接数 | 当前 RSS | 2.6.4 RSS | 当前 PSS | 2.6.4 PSS | 当前 USS | 2.6.4 USS | USS 变化 | 当前 Anonymous | 2.6.4 Anonymous |

+
+0 条和 1 条连接之间的小幅反向波动属于分配器回收和采样时序噪声，
+不能解释为连接产生负开销。使用 0 到 66 条连接的跨度估算单位
+连接成本更稳定。

+
+当前分支的每连接独占内存增量下降约 37.4%。
+
+## 固定 1 Gbit/s 活跃流量
+
+为排除两个版本最大吞吐不同造成的缓冲区差异，使用
+`iperf3 -b 1G -P 1 -t 20` 将两个版本都限制为 1 Gbit/s。

+
+## 解释和限制
+
+1. 以固定 1 Gbit/s 场景为例，当前分支 RSS 增加 5.0%，但
+   Anonymous 下降 39.7%，PSS 下降 1.0%。这说明差异主要体现
+   在非匿名或共享驻留页；本次没有保存逐 VMA 数据，因此不进一步
+   将它归因到某一个具体映射。
+2. 两个相同版本进程运行在同一宿主机时会共享可执行文件代码页，
+   所以 PSS 比 RSS 更适合估算该测试拓扑的宿主机总成本，USS 和
+   Anonymous 更适合判断 EasyTier 私有堆及缓冲区的变化。
+3. 这是一轮受控 A/B 测试，而不是长期统计分布。数值可用于确认
+   差异方向和量级；若作为发布门禁，应固定机器负载并增加多轮重复。
+4. 本文只比较 QUIC TCP proxy 内存，不使用未限速吞吐结果推断性能，
+   避免吞吐差异污染内存结论。

+```
+
+## 使用示例
+
+### 基本使用
+
+```java
+import com.easytier.jni.EasyTierJNI;
+import java.util.Map;
+
+public class EasyTierManager {
+    
+    // 初始化网络实例
+    public void startNetwork() {
+        String config = """
+            inst_name = "my_instance"
+            network = "my_network"
+            """; 
+        
+        try {
+            // 解析配置
+            int result = EasyTierJNI.parseConfig(config);
+            if (result != 0) {
+                String error = EasyTierJNI.getLastError();
+                throw new RuntimeException("配置解析失败: " + error);
+            }
+            
+            // 启动网络实例
+            result = EasyTierJNI.runNetworkInstance(config);
+            if (result != 0) {
+                String error = EasyTierJNI.getLastError();
+                throw new RuntimeException("网络实例启动失败: " + error);
+            }
+            
+            System.out.println("EasyTier 网络实例启动成功");
+            
+        } catch (RuntimeException e) {
+            System.err.println("启动失败: " + e.getMessage());
+        }
+    }
+    
+    // 获取网络信息
+    public void getNetworkInfo() {
+        try {
+            Map<String, String> infos = EasyTierJNI.collectNetworkInfosAsMap(10);
+            for (Map.Entry<String, String> entry : infos.entrySet()) {
+                System.out.println(entry.getKey() + ": " + entry.getValue());
+            }
+        } catch (RuntimeException e) {
+            System.err.println("获取网络信息失败: " + e.getMessage());
+        }
+    }
+    
+    // 停止所有实例
+    public void stopNetwork() {
+        try {
+            int result = EasyTierJNI.stopAllInstances();
+            if (result == 0) {
+                System.out.println("所有网络实例已停止");
+            }
+        } catch (RuntimeException e) {
+            System.err.println("停止网络失败: " + e.getMessage());
+        }
+    }
+}
+```
+
+### 通用 JSON RPC
+
+`EasyTierJNI.callJsonRpc(serviceName, methodName, domainName, payloadJson)` 可以调用已暴露的
+EasyTier RPC 服务，payload 和返回值均为 protobuf JSON。该接口不支持
+`api.manage.WebClientService`；实例启动、保留、删除、信息收集仍使用专用 JNI API。
+
+```java
+String response = EasyTierJNI.callJsonRpc(
+    "api.logger.LoggerRpcService",
+    "get_logger_config",
+    "{}"
+);
+```
+
+### VPN 服务集成
+
+如果您要在 Android VPN 服务中使用：
+
+```java
+public class EasyTierVpnService extends VpnService {
+    
+    @Override
+    public int onStartCommand(Intent intent, int flags, int startId) {
+        // 建立 VPN 连接
+        ParcelFileDescriptor vpnInterface = establishVpnInterface();
+        
+        if (vpnInterface != null) {
+            int fd = vpnInterface.getFd();
+            
+            // 设置 TUN 文件描述符
+            try {
+                EasyTierJNI.setTunFd("my_instance", fd);
+            } catch (RuntimeException e) {
+                Log.e("EasyTier", "设置 TUN FD 失败", e);
+            }
+        }
+        
+        return START_STICKY;
+    }
+    
+    private ParcelFileDescriptor establishVpnInterface() {
+        Builder builder = new Builder();
+        builder.setMtu(1500);
+        builder.addAddress("10.0.0.2", 24);
+        builder.addRoute("0.0.0.0", 0);
+        builder.setSession("EasyTier VPN");
+        
+        return builder.establish();
+    }
+}
+```

+
+## 故障排除
+
+### 常见问题
+
+1. **构建失败: "Android NDK not found"**
+   - 确保设置了 `ANDROID_NDK_ROOT` 环境变量
+   - 检查 NDK 路径是否正确
+
+2. **运行时错误: "java.lang.UnsatisfiedLinkError"**
+   - 确保 `.so` 文件放在正确的 `jniLibs` 目录下
+   - 检查目标架构是否匹配
+
+3. **配置解析失败**
+   - 检查 TOML 配置格式是否正确
+   - 使用 `getLastError()` 获取详细错误信息
+
+### 调试技巧
+
+- 启用 Android 日志查看 JNI 层的日志输出
+- 使用 `adb logcat -s EasyTier-JNI` 查看相关日志
+- 检查 `getLastError()` 返回的错误信息

+# Native data-plane ABI v3
+
+The native data-plane ABI is a thin adapter over the instance-owned
+`DataPlaneSession`. It does not own sockets, operation state, completion
+queues, routing policy, or timeouts.
+
+## Conventions
+
+- Every immediate call returns `0` on success or a negative
+  `DataPlaneErrorKind` value on failure.
+- `data_plane_completion_wait` returns `1` when a completion is ready, `0` on
+  timeout or session close, and a negative error value on failure.
+- `data_plane_completion_drain` returns a non-negative descriptor count or a
+  negative error value.
+- Handle zero is invalid.
+- `timeout_ms == UINT64_MAX` means no deadline.
+- TCP connect/bind/accept and UDP bind timeouts start when submission is
+  accepted.
+- TCP streams and UDP sockets have persistent read and write deadlines.
+  `data_plane_resource_deadline_set` replaces the selected directions'
+  deadlines immediately, including for active operations. An expired deadline
+  remains expired until it is replaced or cleared with `UINT64_MAX`.
+- Deadline direction `1` selects reads, `2` selects writes, and `3` selects
+  both.
+- Request and write bytes are copied before a submit call returns.
+- Socket-address fields use native-endian integers. Address bytes are in
+  network order. ABI v3 accepts IPv4 only.
+
+`DataPlaneSocketAddr` is:
+
+```c
+typedef struct {
+    uint16_t family;      /* 4 */
+    uint16_t port;
+    uint8_t address[16];  /* IPv4 uses the first four bytes */
+} DataPlaneSocketAddr;
+```
+
+`DataPlaneCompletion` is:
+
+```c
+typedef struct {
+    uint64_t operation_id;
+    uint16_t operation_kind;
+    uint16_t status; /* 0 or DataPlaneErrorKind */
+} DataPlaneCompletion;
+```
+
+## Lifecycle
+
+One native session may be open for an EasyTier instance at a time:
+
+```text
+data_plane_session_open
+  -> set resource deadlines
+  -> submit operations
+  -> completion_wait
+  -> completion_drain
+  -> typed result_take
+  -> resource_close / operation_free
+data_plane_session_close
+```
+
+Closing a native session cancels and discards its outstanding operations and
+resources and wakes a thread blocked in `data_plane_completion_wait`.
+
+The resource and operation IDs returned by the ABI belong to that session.
+They must always be passed together with the same session handle.
+
+## Completion and result ownership
+
+Submission returns an operation ID immediately. Completion descriptors carry
+only the operation ID, operation kind, and terminal status. Draining a
+descriptor makes its typed result available but does not consume it.
+
+`data_plane_result_size` reports the TCP-read or UDP-receive payload size.
+Typed result-take functions consume the result exactly once. If a supplied
+buffer is too small, they return `-BufferTooSmall` and leave the result
+available for a later call.
+
+Call `data_plane_operation_free` when a drained result is intentionally
+abandoned. Call `data_plane_resource_close` for TCP streams, listeners, and
+UDP sockets.
+
+## Operation kinds
+
+| Value | Operation |
+| ---: | --- |
+| 1 | TCP connect |
+| 2 | TCP bind |
+| 3 | TCP accept |
+| 4 | TCP read |
+| 5 | TCP write |
+| 6 | UDP bind |
+| 7 | UDP receive |
+| 8 | UDP send |
+
+The exported function families are:
+
+- `data_plane_tcp_*_submit`
+- `data_plane_udp_*_submit`
+- `data_plane_resource_deadline_set`
+- `data_plane_completion_wait`
+- `data_plane_completion_drain`
+- `data_plane_*_result_take`
+- `data_plane_operation_cancel`
+- `data_plane_operation_free`
+- `data_plane_resource_close`

+# easytier-mini
+
+`easytier-mini` is a native EasyTier POC binary. It shares EasyTier's TOML
+configuration model, peer protocol, TCP/UDP tunnel implementations, TUN,
+dynamic IPv4 allocation, the smoltcp userspace path and STUN/UDP hole-punching
+core with the full binary. It includes AES-GCM so its default encryption
+setting interoperates with the full binary's default configuration.
+
+Build it with:
+
+```sh
+cargo build --release -p easytier-mini
+```
+
+For the static size target used by this POC:
+
+```sh
+cargo build --profile mini --target x86_64-unknown-linux-musl -p easytier-mini
+```
+
+MIPS targets use the repository's existing musl-cross toolchains. The helper
+builds the standard library for size, applies immediate-abort only to the mini
+MIPS target graph, and can build either or both byte orders:
+
+```sh
+./easytier-contrib/easytier-mini/build-mips.sh all
+./easytier-contrib/easytier-mini/build-mips.sh mips
+./easytier-contrib/easytier-mini/build-mips.sh mipsel
+```
+
+The `mini` profile derives from `release` and applies `opt-level=z` to the
+entire compact binary dependency graph. Full EasyTier release builds retain
+their normal `opt-level=3` profile. The musl builds use a mini-only static
+linker policy to stay below 5,000,000 bytes on x86-64 and 5,500,000 bytes on
+MIPS without UPX or another executable compressor. The compact x86-64 linker
+policy retains static PIE, packs relative relocations and folds identical code.
+MIPS builds omit standard-library backtrace support and use immediate abort;
+normal workspace MIPS builds are not affected. Compact linker policies omit
+unwind tables.
+
+Start it with a normal EasyTier TOML file:
+
+```sh
+easytier-mini --config mini.toml
+```
+
+`-c` is accepted as the short form of `--config`.
+
+Start it as an EasyTier Web managed node with a complete config-server URL:
+
+```sh
+easytier-mini --config-server udp://config-server.easytier.cn:22020/TOKEN
+```
+
+`--machine-id`, `--hostname`, and `--secure-mode` match the full client's Web
+identity and transport options. `--config` and `--config-server` may be used
+together: the local instance remains static while Web-owned instances are
+created, updated, retained, and deleted independently.
+
+The node also exposes the native EasyTier management RPC protocol on
+`127.0.0.1:15888`, so the full `easytier-cli` can inspect it:
+
+```sh
+easytier-cli node info
+easytier-cli peer
+easytier-cli route
+easytier-cli connector list
+```
+
+For example:
+
+```toml
+instance_name = "mini"
+ipv4 = "10.147.0.2"
+listeners = ["tcp://0.0.0.0:11010", "udp://0.0.0.0:11010"]
+
+[network_identity]
+network_name = "mini-poc"
+network_secret = "change-me"
+
+[[peer]]
+uri = "tcp://example.net:11010"
+```
+
+Local TOML and Web configuration both retain the complete authoritative model.
+The compact runtime silently omits unsupported capabilities while normalizing
+that model into live runtime state. EasyTier Web therefore sees every accepted
+configuration value unchanged and its consistency checks converge. This also
+applies to hot patches: for example, a port-forward patch remains visible to
+the controller while no port-forward service starts in mini. ChaCha20 falls
+back to AES-GCM rather than plaintext.
+
+The compact runtime supports `tcp://` and `udp://` listener, mapped-listener
+and peer URLs. `no_tun = true` runs through smoltcp without an OS TUN device,
+and `dhcp = true` allocates the virtual IPv4 address dynamically.
+
+The mini feature set keeps STUN collection, UDP hole punching, Web heartbeats,
+Web instance lifecycle management and the config hot-patch RPC. It omits TCP
+hole punching, endpoint discovery (`http://`, `https://`, `txt://` and
+`srv://` peers), protobuf reflection, logger control and the rest of the full
+management surface. Unsupported connector URLs are accepted as no-ops. Its
+local RPC surface remains read-only for node, peer, route and connector
+queries. OSPF route messages keep their original protobuf wire data, so fields
+added by future EasyTier versions are forwarded without requiring
+`prost-reflect`.
+
+For size, this POC reads one file directly and does not support configuration
+from stdin or `${VAR}` expansion. It omits the process-management event journal,
+while the console logger still reports runtime events such as peer, connection,
+listener, TUN and DHCP changes. The RPC address is currently fixed, so only one
+mini process can use the default portal on a host. The x86-64 musl POC cannot
+provide reliable stack backtraces because its release binary has no unwind
+tables.

+# OpenHarmonyOS 项目构建说明
+
+本项目需要 OpenHarmonyOS SDK 和多个基础库支持才能成功编译。请按照以下步骤准备构建环境。
+如存在任何编译问题，请前往[Easytier for OHOS](https://github.com/FrankHan052176/EasyTier)
+
+## 前置要求
+
+### 1. 安装 OpenHarmonyOS SDK
+
+**SDK 下载链接**：  
+[OpenHarmony 每日构建版本](https://ci.openharmony.cn/workbench/cicd/dailybuild/dailylist)
+
+**版本要求**：  
+请选择版本号 **小于 OpenHarmony_5.1.0.58** 的 ohos-sdk-full 版本
+
+下载后请解压到适当位置（如 `/usr/local/ohos-sdk`），并记下安装路径。
+
+### 2. 编译依赖库
+在编译本项目前，需要先自行编译以下四个基础库：
+
+- glib
+- libffi
+- pcre2
+- zlib
+
+这些库需要使用 OpenHarmonyOS 的工具链进行交叉编译。
+
+## 环境配置
+
+### 1. 设置环境变量
+创建并运行以下脚本设置环境变量（请根据您的实际 SDK 安装路径修改）：
+
+```bash
+#!/bin/bash

+                   GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.
