+# PROJECT KNOWLEDGE BASE
+
+**Generated:** Mon Feb 02 2026
+**Commit:** 7ca01ab
+**Branch:** beta
+
+## OVERVIEW
+FLVX (formerly Flux Panel) is a traffic forwarding management system built on a forked GOST v3 stack. It ships as a Go-based admin API (SQLite) + Vite/React UI + Go forwarding agent, with optional mobile WebView wrappers.
+
+## STRUCTURE
+```
+./
+├── go-gost/               # Go forwarding agent (forked gost + local x/)
+│   └── x/                 # Local fork of github.com/go-gost/x (replace => ./x)
+├── go-backend/            # Go Admin API (SQLite, net/http)
+├── vite-frontend/         # React/Vite dashboard (HeroUI + Tailwind)
+├── docker-compose-v4.yml  # Panel deploy (IPv4-only bridge)
+├── docker-compose-v6.yml  # Panel deploy (IPv6-enabled bridge)
+├── panel_install.sh       # Panel installer/upgrader (downloads compose)
+├── install.sh             # Node installer/upgrader (downloads gost binary)
+└── .github/workflows/     # CI: build/push images + release artifacts
+```
+
+## WHERE TO LOOK
+| Task | Location | Notes |
+|------|----------|-------|
+| **Deploy (Docker)** | `docker-compose-v4.yml` | Env: `JWT_SECRET`, `BACKEND_PORT`, `FRONTEND_PORT` |
+| **Deploy (IPv6)** | `docker-compose-v6.yml` | Same as v4 + IPv6-enabled bridge |
+| **Panel install** | `panel_install.sh` | Picks v4/v6, generates `JWT_SECRET`, downloads compose |
+| **Node install** | `install.sh` | Installs `/etc/flux_agent/flux_agent` + writes `config.json`/`gost.json` + systemd `flux_agent.service` |
+| **Admin API** | `go-backend/` | Go Admin API (SQLite) |
+| **Web UI** | `vite-frontend/` | React/Vite dashboard (HeroUI + Tailwind) |
+| **Go Agent** | `go-gost/` | Forwarding agent (forked gost + local x/) |
+| **Go Core** | `go-gost/x/` | Handlers/listeners/dialers + management API |
+
+## CODE MAP
+| Symbol | Type | Location | Role |
+|--------|------|----------|------|
+| `flvx` | Project | `.` | Root directory |
+| `main` | Func | `go-backend/cmd/paneld/main.go` | Backend Entry |
+| `App` | Component | `vite-frontend/src/App.tsx` | Frontend Entry |
+| `main` | Func | `go-gost/main.go` | Agent Entry |
+
+
+## CONVENTIONS
+- `Authorization` header carries the raw JWT token (no `Bearer` prefix) between `vite-frontend/` and `springboot-backend/`.
+- `go-gost/` uses `replace github.com/go-gost/x => ./x` and `go-gost/x/` is also its own Go module.
+
+## ANTI-PATTERNS (THIS PROJECT)
+- Do not edit generated protobuf output: `go-gost/x/internal/util/grpc/proto/*.pb.go`, `go-gost/x/internal/util/grpc/proto/*_grpc.pb.go`.
+
+## COMMANDS
+```bash
+# Panel (Docker)
+docker compose -f docker-compose-v4.yml up -d
+docker compose -f docker-compose-v6.yml up -d
+
+# Release-based install scripts
+./panel_install.sh
+./install.sh
+
+# Local dev (per subproject)
+(cd springboot-backend && mvn clean package)
+(cd vite-frontend && npm run dev)
+(cd go-gost && go run .)
+```
+
+## NOTES
+- LSP servers are not installed in this environment (gopls/jdtls/typescript-language-server); rely on grep-based navigation.
+- `vite-frontend/vite.config.ts` sets `minify: false` and disables treeshake; expect larger bundles.

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"

+# 安装部署指南
+
+本文档介绍如何部署 FLVX 面板端及节点端。
+
+## 一、面板端部署
+
+面板端负责管理用户、节点和转发规则。
+
+### 1. 环境要求
+- 操作系统：Linux (推荐 Debian 10+ / Ubuntu 20.04+)
+- 必须安装 Docker 和 Docker Compose
+
+### 2. 一键安装脚本
+
+使用以下命令即可快速安装面板：
+
+```bash
+curl -L https://raw.githubusercontent.com/Sagit-chu/flux-panel/main/panel_install.sh -o panel_install.sh && chmod +x panel_install.sh && ./panel_install.sh
+```
+
+**安装过程中会提示输入以下信息：**
+- **前端端口**: 默认为 `6366`
+- **后端端口**: 默认为 `6365`
+
+脚本会自动检测系统是否支持 IPv6，并自动配置 Docker 的 IPv6 支持。
+
+### 3. 访问面板
+
+安装完成后，访问：
+`http://<服务器IP>:<前端端口>` (默认: `http://<服务器IP>:6366`)
+
+**默认管理员账号：**
+- 用户名: `admin_user`
+- 密码: `admin_user`
+
+> ⚠️ **注意**: 首次登录后，请务必在“个人中心”或“设置”中修改默认密码！
+
+### 4. 维护命令
+
+再次运行 `./panel_install.sh` 脚本可以看到管理菜单：
+1. 安装面板
+2. 更新面板
+3. 卸载面板
+
+---
+
+## 二、节点端部署
+
+节点端运行在实际进行流量转发的服务器上，需要连接到面板端进行管理。
+
+### 1. 获取接入密钥
+1. 登录面板端。
+2. 进入 **节点管理 (Node)** 页面。
+3. 点击 **添加节点**。
+4. 获取该节点的 **接入密钥 (Secret)**。
+
+### 2. 一键安装脚本
+
+在节点服务器上运行：
+
+```bash
+curl -L https://raw.githubusercontent.com/Sagit-chu/flux-panel/main/install.sh -o install.sh && chmod +x install.sh && ./install.sh
+```
+
+**安装过程中会提示输入：**
+- **服务器地址**: 面板端的通信地址（通常是 `http://<面板IP>:<后端端口>`，例如 `http://1.2.3.4:6365`）。
+- **密钥**: 刚才在面板中获取的节点密钥。
+
+或者直接使用带参数的命令（适用于自动化部署）：
+
+```bash
+# 替换 <面板地址> 和 <密钥>
+./install.sh -a "http://1.2.3.4:6365" -s "your_node_secret"
+```
+
+### 3. 验证安装
+安装完成后，服务会自动启动。
+- 查看状态: `systemctl status flux_agent`
+- 回到面板 **节点管理** 页面，该节点状态应显示为 **在线**。

+# 使用指南
+
+## 1. 仪表盘 (Dashboard)
+登录系统后首先看到的是仪表盘，这里展示了系统的整体运行状态，包括：
+- 在线节点数量
+- 用户总数
+- 流量统计信息
+
+## 2. 节点管理 (Node)
+节点是实际承载流量转发的服务器。
+- **添加节点**: 点击“添加”，获取密钥用于节点端安装。
+- **管理**: 可以查看节点在线状态、版本信息，以及对节点进行编辑或删除。
+
+## 3. 用户管理 (User)
+管理员可以创建和管理普通用户。
+- **创建用户**: 设置用户名、密码、流量配额等。
+- **用户组**: 可以将用户分配到不同的组 (Group)，便于统一管理权限或策略。
+
+## 4. 转发管理 (Forward)
+这是核心功能区，用于设置端口转发规则。
+- **端口转发**: 将节点服务器的某个端口流量转发到目标地址。
+    - **协议**: 支持 TCP / UDP。
+    - **入口**: 选择入口节点和监听端口。
+    - **出口**: 设置目标 IP 和端口。
+- **隧道转发**: 用于更复杂的网络穿透场景（具体配置视业务需求而定）。
+
+## 5. 限制与策略 (Limit)
+- **限速**: 可以对指定用户或指定隧道进行带宽限制，防止资源滥用。
+- **计费模式**: 支持配置流量计算方式（单向或双向），适合运营场景。
+
+## 6. 系统配置 (Config)
+在此页面进行系统的全局设置。
+
+## 7. 个人设置 (Profile)
+- **修改密码**: 为了安全，建议定期修改管理员密码。

-<h1 id="faq">常见问题 (FAQ)</h1>
-<h3 id="q1-docker-command-not-found">Q1: 安装脚本提示 "Docker command not found"？</h3>
-<p><strong>A</strong>: 请确保您的系统已安装 Docker 和 Docker Compose。
-- Ubuntu/Debian 安装 Docker: <code>curl -fsSL https://get.docker.com | bash</code></p>
-<h3 id="q2-connection-refused">Q2: 面板无法访问 (Connection Refused)？</h3>
-<p><strong>A</strong>:
-1. 检查防火墙是否放行了前端端口（默认 <code>6366</code>）。
-2. 检查容器是否正常运行: <code>docker ps</code>。
-3. 查看容器日志: <code>docker logs flux-panel-backend</code> 或 <code>docker logs vite-frontend</code>。</p>
-<h3 id="q3">Q3: 节点显示离线？</h3>
-<p><strong>A</strong>:
-1. 检查节点服务器与面板服务器之间的网络连通性。
-2. 确认在节点端安装时输入的 <strong>面板地址</strong> 和 <strong>密钥</strong> 是否正确。
-3. 检查节点端服务状态: <code>systemctl status flux_agent</code>。
-4. 查看节点端日志: <code>journalctl -u flux_agent -f</code>。</p>
-<h3 id="q4-tcp-udp">Q4: 只有 TCP 能通，UDP 不通？</h3>
-<p><strong>A</strong>: 请检查服务器防火墙和安全组（AWS/阿里云/腾讯云等）是否同时放行了对应端口的 <strong>TCP 和 UDP</strong> 协议。</p>
-<h3 id="q5-ipv6">Q5: IPv6 无法使用？</h3>
-<p><strong>A</strong>: 面板安装脚本会自动尝试配置 Docker 的 IPv6。如果失败，请手动检查 <code>/etc/docker/daemon.json</code> 配置，确保 <code>ipv6: true</code> 且分配了正确的 <code>fixed-cidr-v6</code> 子网。</p>
-<h3 id="q6-postgresql">Q6: 如何切换到 PostgreSQL？</h3>
-<p><strong>A</strong>: 在 <code>.env</code> 文件中设置 <code>DB_TYPE=postgres</code>，并让 <code>DATABASE_URL</code> 与 <code>POSTGRES_*</code> 保持一致，然后执行 <code>docker compose up -d</code> 重启服务即可。使用安装脚本部署时，<code>POSTGRES_PASSWORD</code> 会自动随机生成并写入 <code>.env</code>。详见 <a href="../postgresql/">PostgreSQL 数据库指南</a>。</p>
-<h3 id="q7-sqlite-postgresql">Q7: 从 SQLite 迁移到 PostgreSQL 后数据丢失？</h3>
-<p><strong>A</strong>:
-1. 确认迁移前已备份 SQLite 文件（<code>gost.db.bak</code>）。
-2. 确认 <code>pgloader</code> 命令执行成功，检查其输出是否有报错。
-3. 确认 <code>.env</code> 中 <code>DATABASE_URL</code> 的密码与 <code>POSTGRES_PASSWORD</code> 一致。
-4. 详细迁移步骤参考 <a href="../postgresql/">PostgreSQL 数据库指南 - 从 SQLite 迁移</a>。</p>
-<h3 id="q8-postgresql">Q8: PostgreSQL 容器启动失败？</h3>
-<p><strong>A</strong>:
-1. 检查 <code>POSTGRES_PASSWORD</code> 是否已设置（不能为空）。
-2. 查看容器日志：<code>docker logs flux-panel-postgres</code>。
-3. 如果是首次启动后修改了密码，需要删除旧的数据卷重新初始化：<code>docker volume rm postgres_data</code>。</p>

+# GO BACKEND KNOWLEDGE BASE
+
+## OVERVIEW
+Go-based Admin API for FLVX (formerly Flux Panel). Replaces the legacy Spring Boot backend.
+**Stack:** Go 1.23, net/http (std lib), SQLite (modernc.org/sqlite).
+
+## STRUCTURE
+```
+go-backend/
+├── cmd/paneld/main.go        # Entry point; starts HTTP server + WebSocket
+├── internal/
+│   ├── http/                 # HTTP layer
+│   │   ├── router.go         # Routes (NewServeMux) + Middleware chain
+│   │   ├── handler/          # API Handlers (User, Tunnel, Node, etc.)

+```
+
+## WHERE TO LOOK
+| Task | Location | Notes |
+|------|----------|-------|
+| **API Routes** | `go-backend/internal/http/router.go` | Registers handlers to `http.ServeMux` |
+| **DB Schema** | `go-backend/internal/store/sqlite/sql/schema.sql` | Embedded in binary |
+| **SQL Queries** | `go-backend/internal/store/sqlite/repository.go` | Raw SQL, no ORM |
+| **Auth Middleware** | `go-backend/internal/http/middleware/jwt.go` | Extracts `Authorization` header |
+| **WebSocket** | `go-backend/internal/ws/` | Real-time updates (traffic, status) |
+
+## CONVENTIONS
+- **No ORM**: Uses raw SQL with `database/sql` and `modernc.org/sqlite`.
+- **Standard Lib**: Uses `net/http` for routing (Go 1.22+ patterns).
+- **Auth**: Expects raw JWT in `Authorization` header (no `Bearer` prefix).
+- **Config**: Loaded from environment variables (see `cmd/paneld/main.go`).

+# GO-GOST SERVICE KNOWLEDGE BASE
+
+**Generated:** Mon Feb 02 2026
+
+## OVERVIEW
+Forwarding agent built on GOST v3 with a local fork of `github.com/go-gost/x` under `x/`.
+**Stack:** Go 1.23, github.com/go-gost/core v0.3.1, local `go-gost/x` module.
+
+## STRUCTURE
+```
+go-gost/
+├── main.go           # Entry; reads panel config.json; starts svc.Run(program)
+├── config.go         # Panel config.json loader (addr/secret + ports)
+├── program.go        # GOST runtime: parse config, run/reload services
+├── x/                # Local fork of github.com/go-gost/x (has its own go.mod)
+└── go.mod            # replace github.com/go-gost/x => ./x
+```
+
+## WHERE TO LOOK
+| Task | Location | Notes |
+|------|----------|-------|
+| Panel integration config | `go-gost/config.go` | Expects `config.json` in cwd by default |
+| Service lifecycle/reload | `go-gost/program.go` | Parses config; handles SIGHUP reload |
+| WebSocket reporting | `go-gost/main.go` | Starts reporter + sets HTTP report URL |
+| Protocol behaviors | `go-gost/x/` | Handlers/listeners/dialers live here |
+
+## CONVENTIONS
+- Two configs exist: panel integration uses `config.json`; forwarding services use GOST config (defaults to `gost.{json,yaml}` via viper search paths).
+- `go-gost/x/` is the primary extension surface; avoid editing vendored deps.
+
+## COMMANDS
+```bash
+cd go-gost
+go run .
+go test ./...
+go build .
+```
