 Commit Message: 配置下发也没兼容，请全量检查一下，哪些功能需要一起改造
 ## Prompts
 ### Prompt 1
 211 任务的没有完全完成1. 选择IP后诊断还会诊断默认IP
 2. 选择隧道出口IP后，入口还是会链接默认IP，没有链接选择的IP
 请分析后制定修复计划
 ### Prompt 2
 配置下发也没兼容，请全量检查一下，哪些功能需要一起改造
 ## Summary
 你提得很对，我按“配置下发全链路”重新过了一遍（只读分析）。结论是：**需要一起改造的不是一个点，而是“诊断链路 + 重部署链路 + 回归测试链路”**。
 目前状态可以分成三类：
 - **已兼容（创建/更新时下发）**
  - 隧道创建/更新时，`connectIp` 已进入运行时下发选择逻辑（`selectTunnelDialHost`）。
  - 本地/联邦 runtime apply 都会吃 `target.ConnectIP`（前提是 state 里有值）。
  - 参考：`go-backend/internal/http/handler/mutations.go:2588`, `go-backend/internal/http/handler/mutations.go:2348`
 - **未兼容（你反馈的核心问题）**
  - 诊断链路未传 `connectIp`，导致总走默认IP。
  - 参考：`go-backend/internal/http/handler/control_plane.go:75`, `go-backend/internal/http/handler/control_plane.go:1102`
 - **半兼容（配置重建时丢字段）**
  - 重部署时从 DB 重建 runtime state，**没把 `ConnectIP` 带回去**，所以 redeploy 后会回退默认IP。
  - 参考：`go-backend/internal/http/handler/mutations.go:883`, `go-backend/internal/http/handler/mutations.go:897`
 ---
 **需要一起改造的功能范围（建议一次性做完）**
 - `诊断（非流式 + 流式）`
  - 隧道诊断、转发诊断都要改（共用 `prepare*Diagnosis` + `appendChainHopDiagnosis`）。
  - 流式 start 预览项也要改，否则 UI 一开始仍显示默认IP。
  - 目标文件：`go-backend/internal/http/handler/control_plane.go`, `go-backend/internal/http/handler/diagnosis_stream.go`
 - `配置下发（重部署路径）`
  - 单条重部署、批量重部署都依赖 `reconstructTunnelState`，必须补 `ConnectIP` 回填。
  - 目标文件：`go-backend/internal/http/handler/mutations.go`
 - `联邦节点运行时下发一致性`
  - 逻辑本身已支持 `ConnectIP`，但受上一步 state 丢字段影响；修复后自动恢复一致。
  - 重点验证：remote middle hop `ApplyRole.Targets` 的 Host 选取。
 - `回归测试`
  - 新增诊断用例：选了 `connectIp` 后，`targetIp` 必须是选中值（tunnel/forward + stream start/item）。
  - 新增重部署用例：redeploy 后仍使用 `connectIp`，不回退默认IP。
  - 目标文件建议：`go-backend/tests/contract/diagnosis_contract_test.go`，补 handler 级或 contract 级 redeploy 用例。
 ---
 **实施计划（修复包）**
 1. 修 `diagnosis` 调用链：所有 `resolveChainProbeTarget` 调用传入 `workItem.toNode.ConnectIP`。  
 2. 修 `reconstructTunnelState`：出口节点和中继节点都回填 `ConnectIP`。  
 3. 补测试：覆盖“诊断用选中IP”“重部署不丢IP”“connectIp为空仍走默认”的三组场景。  
 4. 联调验证：创建/更新、诊断、单重部署、批量重部署、联邦节点场景各跑一遍。
 ---
 我建议按这个范围做成一次完整修复（避免只修诊断后你再次遇到“重部署又回退”的问题）。  
 如果你同意，我下一步就按这个“全量改造范围”进入实施。

 Commit Message: 实施
 ## Prompts
 ### Prompt 1
 211任务中，如果选择了指定的入口IP或者出口IP，在节点上应该只监听这个IP地址，而不再是[::]，请检查
 ### Prompt 2
 connectIp 同时用于“上游拨号目标 + 本节点监听绑定”
 ### Prompt 3
 实施
 ## Summary
 已实施完成，并且按你确认的语义实现为：`connectIp` 同时用于“上游拨号目标 + 本节点监听绑定”。
 - 转发服务下发现在会优先使用 `forward_port.in_ip` 作为监听地址，不再固定用节点默认 `[::]`。
 - 隧道服务下发现在会优先使用 `connectIp` 作为监听地址；为空时才回退到节点默认监听地址。
 - IPv6 监听地址统一通过 `processServerAddress(...)` 处理，确保带方括号格式正确。

 - `go-backend/internal/http/handler/control_plane.go:284`

 Commit Message: 再做一轮“跨表全量列对比（model vs 旧库补列逻辑）

 ### Prompt 1

 再做一轮“跨表全量列对比（model vs 旧库补列逻辑）
 ## Summary
 已完成这一轮“跨表全量列对比（model vs 旧库补列逻辑）”，并做了可执行验证。
 我做了什么：
 - 对比了 `model.Node` / `model.Tunnel` 字段与 `prepareSQLiteLegacyColumns` 的补列清单。
 - 结论：
  - `Node` 目前应补的历史增量列：`server_ip_v4`, `server_ip_v6`, `extra_ips`, `tcp_listen_addr`, `udp_listen_addr`, `inx`, `is_remote`, `remote_url`, `remote_token`, `remote_config`
  - `Tunnel` 应补：`inx`, `ip_preference`
 - 我已把这个对齐结果固化为回归测试，新增了一个“更老版本库”场景验证：
  - 新测试：`TestOpenMigratesVeryLegacyNodeAndTunnelColumns`
  - 文件：`go-backend/tests/contract/migration_contract_test.go`
  - 该测试从极简旧表结构启动，验证上述所有列都会被自动补齐。
 - 测试结果：通过
  - `go test ./tests/contract -run "TestOpenMigratesLegacyNodeDualStackColumns|TestOpenMigratesVeryLegacyNodeAndTunnelColumns"`
 最终结论（本轮排查范围内）：
 - **Node/Tunnel 这条旧库升级链路已对齐且有测试兜底**。
 - 你这类 “no such column” 的同类风险，针对这两个核心表已经基本封住。

 ## 节点API和数据访问层完整分析
 ### 1. 节点CRUD相关Repository方法
 #### 核心方法 (`go-backend/internal/store/repo/`)
 | 方法 | 文件位置 | 功能 |
 |------|----------|------|
 | `CreateNode()` | `repository_mutations.go:199` | 创建节点，处理 serverIP/serverIPV4/serverIPV6 |
 | `UpdateNode()` | `repository_mutations.go:241` | 更新节点，包含所有IP字段 |
 | `DeleteNodeCascade()` | `repository_mutations.go:299` | 级联删除节点（关联 ForwardPort、ChainTunnel、FederationTunnelBinding） |
 | `GetNodeByID()` | `repository.go:555` | 通过ID获取节点 |
 | `GetNodeBySecret()` | `repository.go:540` | 通过Secret获取节点 |
 | `GetNodeStatusFields()` | `repository_mutations.go:229` | 获取节点状态字段 |
 | `GetNodeSecret()` | `repository_mutations.go:263` | 获取节点密钥 |
 | `GetNodeRemoteFields()` | `repository_mutations.go:317` | 获取远程节点字段 |
 | `GetNodePortRange()` | `repository_mutations.go:336` | 获取节点端口范围 |
 | `UpdateNodeOrder()` | `repository_mutations.go:287` | 更新节点排序 |
 | `UpdateNodeOnline()` | `repository.go:570` | 更新节点在线状态 |
 | `UpdateNodeStatus()` | `repository.go:580` | 更新节点状态 |
 | `ListNodes()` | `repository.go:625` | 列出所有节点（返回JSON map格式） |
 | `GetNodeRecord()` | `repository_control.go:131` | 获取 NodeRecord 视图对象 |
 | `CreateRemoteNode()` | `repository_federation.go:266` | 创建远程节点（联邦场景） |
 | `exportNodes()` | `repository.go:1660` | 导出节点数据（用于备份） |
 | `importNodes()` | `repository.go:2016` | 导入节点数据（用于恢复） |

 ### 2. 节点数据结构定义
 #### GORM模型 (`model.Node` - 数据库存储)
 **文件:** `/go-backend/internal/store/model/model.go:59-82`
 ```go
 type Node struct {
    ID            int64          `gorm:"primaryKey;autoIncrement"`
    Name          string         `gorm:"type:varchar(100);not null"`
    Secret        string         `gorm:"type:varchar(100);not null"`
    ServerIP      string         `gorm:"column:server_ip;type:varchar(100);not null"`
    ServerIPV4    sql.NullString `gorm:"column:server_ip_v4;type:varchar(100)"`  // 注意：V大写
    ServerIPV6    sql.NullString `gorm:"column:server_ip_v6;type:varchar(100)"`
    // ... 其他字段
 }
 ```
 #### 控制平面视图 (`model.NodeRecord`)
 **文件:** `/go-backend/internal/store/model/model.go:515-531`
 ```go
 type NodeRecord struct {
    ID            int64
    Name          string
    ServerIP      string
    ServerIPv4    string   // 注意：v小写
    ServerIPv6    string
    Status        int
    PortRange     string
    // ... 其他字段
 }
 ```
 #### JSON导出格式 (`model.NodeBackup`)
 **文件:** `/go-backend/internal/store/model/model.go:333-356`
 ```go
 type NodeBackup struct {
    ID            int64  `json:"id"`
    Name          string `json:"name"`
    ServerIP      string `json:"serverIp"`
    ServerIPv4    string `json:"serverIpV4,omitempty"`
    ServerIPv6    string `json:"serverIpV6,omitempty"`
    // ... 其他字段
 }
 ```
 #### Handler层别名
 **文件:** `/go-backend/internal/http/handler/control_plane.go:25`
 ```go
 type nodeRecord = model.NodeRecord  // 类型别名
 ```
 ---
 ### 3. 节点数据返回给前端的格式
 #### ListNodes API (`repository.go:625-652`)
 ```go
 // 返回 map[string]interface{} 格式
 items = append(items, map[string]interface{}{
    "id": n.ID, "inx": n.Inx, "name": n.Name,
    "ip": n.ServerIP, "serverIp": n.ServerIP,      // ip和serverIp都返回
    "serverIpV4":    nullableString(n.ServerIPV4),
    "serverIpV6":    nullableString(n.ServerIPV6),
    "port":          n.Port,
    "tcpListenAddr": n.TCPListenAddr,

 ### 4. ServerIP/ServerIPV4/ServerIPV6 字段处理逻辑
 #### 字段命名约定
 | 层级 | 字段名 | 数据库列名 |
 |------|--------|-----------|
 | `model.Node` | `ServerIPV4`, `ServerIPV6` | `server_ip_v4`, `server_ip_v6` |
 | `model.NodeRecord` | `ServerIPv4`, `ServerIPv6` | - (内存结构) |
 | `model.NodeBackup` | `ServerIPv4`, `ServerIPv6` | - (JSON) |
 | 前端JSON | `serverIpV4`, `serverIpV6` | - |
 #### 模型转换函数 (`repository_control.go:161-201`)
 ```go
 func nodeRecordFromModel(n *model.Node) *model.NodeRecord {
    rec := &model.NodeRecord{
        ID:            n.ID,
        Name:          n.Name,
        ServerIP:      n.ServerIP,
        // ...
    }
    if n.ServerIPV4.Valid {
        rec.ServerIPv4 = strings.TrimSpace(n.ServerIPV4.String)
    }
    if n.ServerIPV6.Valid {
        rec.ServerIPv6 = strings.TrimSpace(n.ServerIPV6.String)
    }
    // ...
 }
 ```
 #### Dual-Stack辅助函数 (`mutations.go:2715-2772`)
 ```go
 // 判断节点是否支持IPv4
 func nodeSupportsV4(node *nodeRecord) bool {
    if strings.TrimSpace(node.ServerIPv4) != "" { return true }
    if strings.TrimSpace(node.ServerIPv6) != "" { return false }
    // 回退到 ServerIP 判断
    legacy := strings.Trim(strings.TrimSpace(node.ServerIP), "[]")
    if ip := net.ParseIP(legacy); ip != nil {
        return ip.To4() != nil
    }
    return true
 }
 // 选择IPv4地址（优先显式字段，回退ServerIP）
 func pickNodeAddressV4(node *nodeRecord) string {
    if v := strings.TrimSpace(node.ServerIPv4); v != "" { return v }
    return strings.TrimSpace(node.ServerIP)
 }
 ```

 ### 5. 扩展节点IP字段需要改动的位置
 如果要添加新的IP字段（如 `ServerIPV4Alt`），需要修改以下位置：
 #### A. 模型层 (`go-backend/internal/store/model/model.go`)
 1. **`model.Node`** - 添加 GORM 字段定义（约第64行）
 2. **`model.NodeRecord`** - 添加视图字段（约第520行）
 3. **`model.NodeBackup`** - 添加JSON字段（约第338行）
 #### B. Repository层 (`go-backend/internal/store/repo/`)
 1. **`repository_mutations.go`**
   - `CreateNode()` 参数和赋值（约第199-227行）
   - `UpdateNode()` 参数和Updates map（约第241-261行）
 2. **`repository_control.go`**
   - `nodeRecordFromModel()` 转换逻辑（约第161-201行）
 3. **`repository_federation.go`**
   - `CreateRemoteNode()` 参数和赋值（约第266-294行）
 4. **`repository.go`**
   - `ListNodes()` JSON返回格式（约第625-652行）
   - `exportNodes()` 导出逻辑（约第1660-1700行）
   - `importNodes()` 导入逻辑（约第2016-2057行）
   - `prepareSQLiteLegacyColumns()` 迁移逻辑（约第263行）
 #### C. Handler层 (`go-backend/internal/http/handler/`)
 1. **`mutations.go`**
   - `nodeCreate()` 请求参数解析（约第234-279行）
   - `nodeUpdate()` 请求参数解析（约第281-336行）
   - `nodeSupportsV4/V6()` 函数逻辑（约第2715-2772行）
   - `pickNodeAddressV4/V6()` 函数逻辑
 #### D. 测试层 (`go-backend/tests/contract/`)
 所有 contract test 中的 `INSERT INTO node` 语句需要更新字段列表

 ## 隧道链路构建流程分析报告
 ### 1. 隧道链路配置发送到节点的代码位置
 **主函数**: `applyTunnelRuntime()` 
 - 文件: `go-backend/internal/http/handler/mutations.go`
 - 行号: 2454-2521
 **核心流程**:
 ```
 applyTunnelRuntime (L2454)
 ├── 入口节点: 发送 AddChains 命令 (L2474)
 ├── 跳转节点: 发送 AddChains (L2496) + AddService (L2502) 命令
 └── 出口节点: 发送 AddService 命令 (L2514)
 ```
 **配置构建函数**:
 | 函数 | 位置 | 作用 |
 |------|------|------|
 | `buildTunnelChainConfig()` | L2567-2624 | 构建转发链配置 |
 | `buildTunnelChainServiceConfig()` | L2626-2652 | 构建服务配置 |
 | `selectTunnelDialHost()` | L2654-2699 | **选择下一跳连接地址** |
 ---
 ### 2. 下一跳连接地址是如何确定的
 **地址选择核心函数**: `selectTunnelDialHost()` (L2654-2699)
 ```go
 // 关键逻辑 (简化版)
 func selectTunnelDialHost(fromNode, toNode *nodeRecord, ipPreference string) (string, error) {
    // 1. 检测源节点和目标节点的 IPv4/IPv6 支持
    fromV4 := nodeSupportsV4(fromNode)
    fromV6 := nodeSupportsV6(fromNode)
    toV4 := nodeSupportsV4(toNode)
    toV6 := nodeSupportsV6(toNode)
    // 2. 根据偏好选择地址
    switch ipPreference {
    case "v6":  // 优先 IPv6
        if fromV6 && toV6 { return pickNodeAddressV6(toNode) }
        if fromV4 && toV4 { return pickNodeAddressV4(toNode) }
    case "v4":  // 优先 IPv4
        if fromV4 && toV4 { return pickNodeAddressV4(toNode) }
        if fromV6 && toV6 { return pickNodeAddressV6(toNode) }
    default:    // 默认优先 IPv4
        if fromV4 && toV4 { return pickNodeAddressV4(toNode) }
        if fromV6 && toV6 { return pickNodeAddressV6(toNode) }
    }
    // 3. 不兼容时报错
    return "", fmt.Errorf("节点链路不兼容")
 }
 ```
 **地址选择优先级** (在 `pickNodeAddressV4/V6` 中, L2755-2773):
 - **IPv4**: `ServerIPv4` > `ServerIP` (旧字段)
 - **IPv6**: `ServerIPv6` > `ServerIP` (旧字段)
 **端口来源** (在 `buildTunnelChainConfig` 中, L2585-2588):
 ```go
 port := target.Port  // 来自 ChainTunnel.Port 字段
 if port <= 0 {
    return nil, errors.New("节点端口不能为空")
 }
 ```
 ---
 ### 3. ChainTunnel.Port 字段的使用流程
 **数据模型** (`model.go` L127-138):
 ```go
 type ChainTunnel struct {
    ID        int64
    TunnelID  int64
    ChainType string      // "1"=入口, "2"=跳转, "3"=出口
    NodeID    int64
    Port      sql.NullInt64  // ★ 连接端口
    Strategy  sql.NullString
    Inx       sql.NullInt64  // 跳转序号
    Protocol  sql.NullString
 }
 ```
 **Port 字段流转**:
 ```

 ListChainNodesForTunnel (repository_control.go L280)
 └── 从 chain_tunnel 表读取 Port 字段 (L295)
    │
    ▼
 reconstructTunnelState (L845)
 └── 将 Port 复制到 tunnelRuntimeNode.Port (L887, L901)
    │
    ▼
 buildTunnelChainConfig (L2567)
 └── 使用 target.Port 构建连接地址 (L2585)
 ```

 | **端口从数据库读取** | `repository_control.go` | L280-343 | `ListChainNodesForTunnel()` |
 **关键配置结构**:
 ```go
 // mutations.go L1950-1957
 type tunnelRuntimeNode struct {
    NodeID    int64
    Protocol  string   // 连接协议
    Strategy  string   // 选择策略
    Inx       int      // 跳转序号
    ChainType int      // 1=入口, 2=跳转, 3=出口

 ### 2. `resolveForwardIngress` 函数 (查询转发时)
 **位置**: `go-backend/internal/store/repo/repository.go:2727-2796`
 ```go
 func resolveForwardIngress(db *gorm.DB, forwardID int64, tunnelID int64) (string, sql.NullInt64, error) {

    if port <= 0 {
        port = h.pickTunnelPort(tunnelID)  // 自动分配端口 (line 1157)
    }
    // 3. 创建转发记录 + forward_port 记录
    forwardID, err := h.repo.CreateForwardTx(..., entryNodes, port, ...)  // line 1179

 ## 入口IP数据流
 ```
 1. 节点注册 → Node表存储 server_ip, server_ip_v4, server_ip_v6
 2. 创建隧道:
   chain_tunnel (入口节点) → buildTunnelInIP() → tunnel.in_ip 字段
 3. 创建转发:
   隧道入口节点IDs → forward_port(forward_id, node_id, port)
 4. 查询转发入口:
   forward_port JOIN node → resolveForwardIngress()
   ├─ 优先使用 tunnel.in_ip (多IP组合)
   └─ 否则用 forward_port 关联的 node.server_ip

  // ===================== Summary of findings ===================
 ## Key File Paths and their purposes:
 ### Frontend: Forward Edit/create dialog component
 - **Main file:** `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/mighty-nebula/vite-frontend/src/pages/forward.tsx`
  - Displays the forwarding list and handles all create/edit/delete/forwards
 - Has `inIp` and `inPort` fields
 - Shows entry port and dialog/form with validation
 - Uses React-hook-form with state management
 - Calls `createForward`, `updateForward`, `deleteForward`, `pauseForwardService`, `resumeForwardService`, APIs
 - Imports API functions from `@/api`
 ### Backend: Forwarding data model and API handlers
 - **Main model file:** `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/mighty-nebula/go-backend/internal/store/model/model.go`
  - GORM model definition for `Forward` struct does basic forwarding configuration
  - Related models: `ForwardPort`, `Tunnel`, `UserForwardDetail` (view struct)
  - **API handlers:** `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/mighty-nebula/go-backend/internal/http/handler/mutations.go`
  - Create/update/delete operations
  - Entry port handling via `inPort` field
 - **Repository layer:** `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/mighty-nebula/go-backend/internal/store/repo/repository_mutations.go`
  - CRUD operations for  - `resolveForwardIngress` function in `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/mighty-nebula/go-backend/internal/store/repo/repository.go`
  - Computes `inIp` and `inPort` from joins
 ### Current data model structure for forwards
 From `go-backend/internal/store/model/model.go`:
 ```go
 // Forward maps to the "forward" table.
 type Forward struct {
    ID          int64         `gorm:"primaryKey;autoIncrement"`
    UserID      int64         `gorm:"column:user_id;not null"`
    UserName    string        `gorm:"column:user_name;type:varchar(100);not null"`
    Name        string        `gorm:"type:varchar(100);not null"`
    TunnelID    int64         `gorm:"column:tunnel_id;not null"`
    RemoteAddr  string        `gorm:"column:remote_addr;type:text;not null"`
    Strategy    string        `gorm:"type:varchar(100);not null;default:'fifo'"`
    InFlow      int64         `gorm:"not null;default:0"`
    OutFlow     int64         `gorm:"column:out_flow;not null;default:0"`
    CreatedTime int64         `gorm:"column:created_time;not null"`

    Status      int           `gorm:"not null"`
    Inx         int           `gorm:"not null;default:0"`
    SpeedID     sql.NullInt64 `gorm:"column:speed_id"`
 }
 ```
 ```go
 // ForwardPort maps to the "forward_port" table - stores port assignments per entry node
 type ForwardPort struct {
    ID        int64 `gorm:"primaryKey;autoIncrement"`
    ForwardID int64 `gorm:"column:forward_id;not null"`
    NodeID    int64 `gorm:"column:node_id;not null"`
    Port      int   `gorm:"not null"`
 }
 ```
 ```go
 // Tunnel maps to the "tunnel" table - has entry IP configuration
 type Tunnel struct {
    ID           int64          `gorm:"primaryKey;autoIncrement"`
    Name         string         `gorm:"type:varchar(100);not null"`
    TrafficRatio float64        `gorm:"column:traffic_ratio;not null;default:1.0"`
    Type         int            `gorm:"not null"`
    Protocol     string         `gorm:"type:varchar(10);not null;default:'tls'"`
    Flow         int64          `gorm:"not null"`
    CreatedTime  int64          `gorm:"column:created_time;not null"`
    UpdatedTime  int64          `gorm:"column:updated_time;not null"`
    Status       int            `gorm:"not null"`
    InIP         sql.NullString `gorm:"column:in_ip;type:text"`       // Optional entry IP hint
    Inx          int            `gorm:"not null;default:0"`
    IPPreference string         `gorm:"column:ip_preference;type:varchar(10);not null;default:''"`
 }
 ```
 ### How entry listener is currently configured:
 1. **Port Storage**: `ForwardPort` table stores the mapping from `forward_id` -> `node_id` -> `port`
   - Port is assigned by the handler or passed via `inPort` parameter ( or auto-picked)
   - Entry nodes are determined by `tunnelEntryNodeIDs()` in handler
 3. **Entry IP Resolution**: The `resolveForwardIngress()` function resolves `inIp` and `inPort` by:
   - Joining `forward_port` with `node` table
   - `inIp` comes from `tunnel.in_ip` if set (takes precedence over node.server_ip)
   - For multi-entry-node forwards, comma-separated IPs and ports are returned
 4. **Current IP-related fields**:
   - `Forward` model: No `inIp` field (port is stored in `forward_port` table)
   - `Tunnel` model: Has `InIP` field (nullable, - allows specifying of a preferred entry IP hint
   - `UserForwardDetail` view struct ( joins tunnel table and includes `InIP` and `InPort`
 5. **No explicit entry IP selection UI in current dialog** - The port field is a text input, and form validates range but but UI doesn't allow setting specific IP addresses

 | `model/model.go` | Node/ForwardPort/ChainTunnel 增加3个字段 |
 | `repository_mutations.go` | CreateNode/UpdateNode 处理 extraIPs 参数 |
 | `repository_control.go` | GetNodeRecord/ListNodeAllIPs 辅助函数 |
 | `repository.go` | resolveForwardIngress 使用 forward_port.in_ip |
 | `handler/mutations.go` | selectTunnelDialHost 优先使用 connectIP |
 #### 前端 (约150行)
 | 页面 | 改动 |
 |------|------|
 | 节点编辑 | 高级配置增加"额外IP" Input（逗号分隔） |
 | 转发编辑 | 入口端口旁增加"监听IP" Select（从入口节点IP选择） |
 | 隧道配置 | 出口节点行增加"连接IP" Select（从出口节点IP选择） |

 ### UI 示意
 **节点编辑 - 高级配置**
 ```
 额外IP地址
 ┌──────────────────────────────────────────┐

                                └─ 10.0.0.5
 ```
 **隧道配置 - 出口节点**
 ```
 出口节点: [ node-1 ▼ ]  端口: [ 8443 ]  连接IP: [ 10.0.0.5 ▼ ]
                                                ├─ 203.0.113.10 (默认)

 ## CONVENTIONS
- **Auth**: `Authorization` header carries the raw JWT token (no `Bearer` prefix) between `vite-frontend/` and `go-backend/`.
+- `Authorization` header carries the raw JWT token (no `Bearer` prefix) between `vite-frontend/` and `springboot-backend/`.
- **Module Fork**: `go-gost/` uses `replace github.com/go-gost/x => ./x` and `go-gost/x/` is also its own Go module.
+- `go-gost/` uses `replace github.com/go-gost/x => ./x` and `go-gost/x/` is also its own Go module.
 - **Encryption**: Agent-to-panel communication uses AES encryption with node `secret` as PSK.
 - **API Envelope**: All REST responses follow `{code, msg, data, ts}` structure (code 0 = success).
 - **Frontend UI Layer**: Import UI primitives from `src/shadcn-bridge/heroui/*` (legacy-compatible facade), not direct `@heroui/*` packages.
 - **Tailwind v4 Semantic Colors**: `src/styles/globals.css` must import `src/styles/tailwind-theme.pcss`; removing it breaks semantic classes like `bg-primary`, `text-foreground`, and `border-input`.
 - **Go Versions**: `go-backend` uses Go 1.24, `go-gost` uses Go 1.23, `go-gost/x` uses Go 1.22.
 ## 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`.
+- 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`.
 - **DO NOT ADD** `Bearer` prefix to Authorization header - expects raw JWT token.
 - **DO NOT MODIFY** `install.sh` or `panel_install.sh` locally - CI overwrites these on release.
 - **DO NOT** let backend handlers call `repo.DB()` directly — add a Repository method instead.
 - **DO NOT ADD** frontend tests - project has no test infrastructure (Vitest/Jest not configured).
 - **DO NOT REINTRODUCE** `@heroui/*` or `@nextui-org/*` dependencies; migration is now shadcn bridge-based.
 - **DO NOT** use `type:jsonb` or `type:serial` in GORM tags (SQLite incompatible).
 - **DO NOT** omit `TableName()` on new models — GORM pluralizes by default.

 ## UNIQUE STYLES
 - **Flat Monorepo**: Language-prefixed dirs (`go-backend`, `go-gost`, `vite-frontend`) instead of `apps/`/`libs/`.
 - **Asymmetric Go Layout**: `go-backend` follows `cmd/<app>/main.go` while `go-gost` uses `root/main.go`.
 - **Frontend Hybrid Mode**: `App.tsx` detects "H5 mode" (mobile WebView) vs desktop, dictating layout strategy.
 - **Experimental Bundler**: `vite-frontend` uses `rolldown-vite` (Rust-based) instead of standard Vite.
 - **Non-minified Builds**: `vite.config.ts` sets `minify: false`, `treeshake: false` for debugging.
 ## NOTES
- LSP servers are not installed in this environment (gopls/typescript-language-server); rely on grep-based navigation.
+- 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.
 - `vite-frontend` uses `rolldown-vite` (experimental Rust bundler) instead of standard Vite.
 - Install scripts (`install.sh`, `panel_install.sh`) self-delete after execution - common pattern in one-liner installs.
 - CI uses UPX compression (`--best --lzma`) on Go binaries before release.
 - CI dynamically injects `PINNED_VERSION` into install scripts and docker-compose files during releases.
 - `panel_install.sh` auto-detects IPv6 and modifies `/etc/docker/daemon.json` to enable IPv6 bridge.
 - Download proxy `https://gcode.hostcentral.cc/` used for GitHub downloads in China/restricted environments.
 - Backend has contract tests in `go-backend/tests/contract/` - frontend has no test infrastructure.
 - `analysis/3x-ui/` contains a separate git repo for reference/comparison - not part of FLVX core.
 - CI workflows: `ci-build.yml` (build check), `docker-build.yml` (multi-arch images + release), `deploy-docs.yml` (MkDocs).
 - PostgreSQL migration supported via `panel_install.sh` menu option using pgloader.
 - Repository layer is large: `repository.go` (83k LOC), `repository_mutations.go` (43k LOC).
 - Button visual parity relies on `vite-frontend/src/shadcn-bridge/heroui/button.tsx` color mapping + `vite-frontend/src/styles/tailwind-theme.pcss` token export.
 ## PLAN DOCUMENT RULE
 - Every new implementation plan must have a dedicated Markdown plan document.
 - Store plan documents under `plans/`.
 - Use an incrementing numeric prefix and a short plan-summary name: `NNN-<plan-summary>.md` (for example, `001-auth-refactor.md`, `002-federation-api-cleanup.md`).
 - The numeric prefix must increase by 1 for each new plan.
 - In each plan document, keep a task checklist and mark each task as completed immediately after finishing it.

-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.

+      To apply the Apache License to your work, attach the following

-measure under any applicable law fulfilling obligations under article

-
+
-  4. Conveying Verbatim Copies.
+       http://www.apache.org/licenses/LICENSE-2.0
-
+
-  You may convey verbatim copies of the Program's source code as you
+   Unless required by applicable law or agreed to in writing, software
-receive it, in any medium, provided that you conspicuously and
+   distributed under the License is distributed on an "AS IS" BASIS,
-appropriately publish on each copy an appropriate copyright notice;
+   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.
-keep intact all notices stating that this License and any
+   See the License for the specific language governing permissions and
-non-permissive terms added in accord with section 7 apply to the code;
+   limitations under the License.
 keep intact all notices of the absence of any warranty; and give all
 recipients a copy of this License along with the Program.
  You may charge any price or no price for each copy that you convey,
 and you may offer support or warranty protection for a fee.
  5. Conveying Modified Source Versions.
  You may convey a work based on the Program, or the modifications to
 produce it from the Program, in the form of source code under the
 terms of section 4, provided that you also meet all of these conditions:
    a) The work must carry prominent notices stating that you modified
    it, and giving a relevant date.
    b) The work must carry prominent notices stating that it is
    released under this License and any conditions added under section
    7.  This requirement modifies the requirement in section 4 to
    "keep intact all notices".
    c) You must license the entire work, as a whole, under this
    License to anyone who comes into possession of a copy.  This
    License will therefore apply, along with any applicable section 7
    additional terms, to the whole of the work, and all its parts,
    regardless of how they are packaged.  This License gives no
    permission to license the work in any other way, but it does not
    invalidate such permission if you have separately received it.
    d) If the work has interactive user interfaces, each must display
    Appropriate Legal Notices; however, if the Program has interactive
    interfaces that do not display Appropriate Legal Notices, your
    work need not make them do so.
  A compilation of a covered work with other separate and independent
 works, which are not by their nature extensions of the covered work,
 and which are not combined with it such as to form a larger program,
 in or on a volume of a storage or distribution medium, is called an
 "aggregate" if the compilation and its resulting copyright are not
 used to limit the access or legal rights of the compilation's users
 beyond what the individual works permit.  Inclusion of a covered work
 in an aggregate does not cause this License to apply to the other
 parts of the aggregate.
  6. Conveying Non-Source Forms.
  You may convey a covered work in object code form under the terms
 of sections 4 and 5, provided that you also convey the
 machine-readable Corresponding Source under the terms of this License,
 in one of these ways:
    a) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by the
    Corresponding Source fixed on a durable physical medium
    customarily used for software interchange.
    b) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by a
    written offer, valid for at least three years and valid for as
    long as you offer spare parts or customer support for that product
    model, to give anyone who possesses the object code either (1) a
    copy of the Corresponding Source for all the software in the
    product that is covered by this License, on a durable physical
    medium customarily used for software interchange, for a price no
    more than your reasonable cost of physically performing this
    conveying of source, or (2) access to copy the
    Corresponding Source from a network server at no charge.
    c) Convey individual copies of the object code with a copy of the
    written offer to provide the Corresponding Source.  This
    alternative is allowed only occasionally and noncommercially, and
    only if you received the object code with such an offer, in accord
    with subsection 6b.
    d) Convey the object code by offering access from a designated
    place (gratis or for a charge), and offer equivalent access to the
    Corresponding Source in the same way through the same place at no
    further charge.  You need not require recipients to copy the
    Corresponding Source along with the object code.  If the place to
    copy the object code is a network server, the Corresponding Source
    may be on a different server (operated by you or a third party)
    that supports equivalent copying facilities, provided you maintain
    clear directions next to the object code saying where to find the
    Corresponding Source.  Regardless of what server hosts the
    Corresponding Source, you remain obligated to ensure that it is
    available for as long as needed to satisfy these requirements.
    e) Convey the object code using peer-to-peer transmission, provided
    you inform other peers where the object code and Corresponding
    Source of the work are being offered to the general public at no
    charge under subsection 6d.
  A separable portion of the object code, whose source code is excluded
 from the Corresponding Source as a System Library, need not be
 included in conveying the object code work.
  A "User Product" is either (1) a "consumer product", which means any
 tangible personal property which is normally used for personal, family,
 or household purposes, or (2) anything designed or sold for incorporation
 into a dwelling.  In determining whether a product is a consumer product,
 doubtful cases shall be resolved in favor of coverage.  For a particular
 product received by a particular user, "normally used" refers to a
 typical or common use of that class of product, regardless of the status
 of the particular user or of the way in which the particular user
 actually uses, or expects or is expected to use, the product.  A product
 is a consumer product regardless of whether the product has substantial
 commercial, industrial or non-consumer uses, unless such uses represent
 the only significant mode of use of the product.
  "Installation Information" for a User Product means any methods,
 procedures, authorization keys, or other information required to install
 and execute modified versions of a covered work in that User Product from
 a modified version of its Corresponding Source.  The information must
 suffice to ensure that the continued functioning of the modified object
 code is in no case prevented or interfered with solely because
 modification has been made.
  If you convey an object code work under this section in, or with, or
 specifically for use in, a User Product, and the conveying occurs as
 part of a transaction in which the right of possession and use of the
 User Product is transferred to the recipient in perpetuity or for a
 fixed term (regardless of how the transaction is characterized), the
 Corresponding Source conveyed under this section must be accompanied
 by the Installation Information.  But this requirement does not apply
 if neither you nor any third party retains the ability to install
 modified object code on the User Product (for example, the work has
 been installed in ROM).
  The requirement to provide Installation Information does not include a
 requirement to continue to provide support service, warranty, or updates
 for a work that has been modified or installed by the recipient, or for
 the User Product in which it has been modified or installed.  Access to a
 network may be denied when the modification itself materially and
 adversely affects the operation of the network or violates the rules and
 protocols for communication across the network.
  Corresponding Source conveyed, and Installation Information provided,
 in accord with this section must be in a format that is publicly
 documented (and with an implementation available to the public in
 source code form), and must require no special password or key for
 unpacking, reading or copying.
  7. Additional Terms.
  "Additional permissions" are terms that supplement the terms of this
 License by making exceptions from one or more of its conditions.
 Additional permissions that are applicable to the entire Program shall
 be treated as though they were included in this License, to the extent
 that they are valid under applicable law.  If additional permissions
 apply only to part of the Program, that part may be used separately
 under those permissions, but the entire Program remains governed by
 this License without regard to the additional permissions.
  When you convey a copy of a covered work, you may at your option
 remove any additional permissions from that copy, or from any part of
 it.  (Additional permissions may be written to require their own
 removal in certain cases when you modify the work.)  You may place
 additional permissions on material, added by you to a covered work,
 for which you have or can give appropriate copyright permission.
  Notwithstanding any other provision of this License, for material you
 add to a covered work, you may (if authorized by the copyright holders of
 that material) supplement the terms of this License with terms:
    a) Disclaiming warranty or limiting liability differently from the
    terms of sections 15 and 16 of this License; or
    b) Requiring preservation of specified reasonable legal notices or
    author attributions in that material or in the Appropriate Legal
    Notices displayed by works containing it; or
    c) Prohibiting misrepresentation of the origin of that material, or
    requiring that modified versions of such material be marked in
    reasonable ways as different from the original version; or
    d) Limiting the use for publicity purposes of names of licensors or
    authors of the material; or
    e) Declining to grant rights under trademark law for use of some
    trade names, trademarks, or service marks; or
    f) Requiring indemnification of licensors and authors of that
    material by anyone who conveys the material (or modified versions of
    it) with contractual assumptions of liability to the recipient, for
    any liability that these contractual assumptions directly impose on
    those licensors and authors.
  All other non-permissive additional terms are considered "further
 restrictions" within the meaning of section 10.  If the Program as you
 received it, or any part of it, contains a notice stating that it is
 governed by this License along with a term that is a further
 restriction, you may remove that term.  If a license document contains
 a further restriction but permits relicensing or conveying under this
 License, you may add to a covered work material governed by the terms
 of that license document, provided that the further restriction does
 not survive such relicensing or conveying.
  If you add terms to a covered work in accord with this section, you
 must place, in the relevant source files, a statement of the
 additional terms that apply to those files, or a notice indicating
 where to find the applicable terms.
  Additional terms, permissive or non-permissive, may be stated in the
 form of a separately written license, or stated as exceptions;
 the above requirements apply either way.
  8. Termination.
  You may not propagate or modify a covered work except as expressly
 provided under this License.  Any attempt otherwise to propagate or
 modify it is void, and will automatically terminate your rights under
 this License (including any patent licenses granted under the third
 paragraph of section 11).
  However, if you cease all violation of this License, then your
 license from a particular copyright holder is reinstated (a)
 provisionally, unless and until the copyright holder explicitly and
 finally terminates your license, and (b) permanently, if the copyright
 holder fails to notify you of the violation by some reasonable means
 prior to 60 days after the cessation.
  Moreover, your license from a particular copyright holder is
 reinstated permanently if the copyright holder notifies you of the
 violation by some reasonable means, this is the first time you have
 received notice of violation of this License (for any work) from that
 copyright holder, and you cure the violation prior to 30 days after
 your receipt of the notice.
  Termination of your rights under this section does not terminate the
 licenses of parties who have received copies or rights from you under
 this License.  If your rights have been terminated and not permanently
 reinstated, you do not qualify to receive new licenses for the same
 material under section 10.
  9. Acceptance Not Required for Having Copies.
  You are not required to accept this License in order to receive or
 run a copy of the Program.  Ancillary propagation of a covered work
 occurring solely as a consequence of using peer-to-peer transmission
 to receive a copy likewise does not require acceptance.  However,
 nothing other than this License grants you permission to propagate or
 modify any covered work.  These actions infringe copyright if you do
 not accept this License.  Therefore, by modifying or propagating a
 covered work, you indicate your acceptance of this License to do so.
  10. Automatic Licensing of Downstream Recipients.
  Each time you convey a covered work, the recipient automatically
 receives a license from the original licensors, to run, modify and
 propagate that work, subject to this License.  You are not responsible
 for enforcing compliance by third parties with this License.
  An "entity transaction" is a transaction transferring control of an
 organization, or substantially all assets of one, or subdividing an
 organization, or merging organizations.  If propagation of a covered
 work results from an entity transaction, each party to that
 transaction who receives a copy of the work also receives whatever
 licenses to the work the party's predecessor in interest had or could
 give under the previous paragraph, plus a right to possession of the
 Corresponding Source of the work from the predecessor in interest, if
 the predecessor has it or can get it with reasonable efforts.
  You may not impose any further restrictions on the exercise of the
 rights granted or affirmed under this License.  For example, you may
 not impose a license fee, royalty, or other charge for exercise of
 rights granted under this License, and you may not initiate litigation
 (including a cross-claim or counterclaim in a lawsuit) alleging that
 any patent claim is infringed by making, using, selling, offering for
 sale, or importing the Program or any portion of it.
  11. Patents.
  A "contributor" is a copyright holder who authorizes use under this
 License of the Program or a work on which the Program is based.  The
 work thus licensed is called the contributor's "contributor version".
  A contributor's "essential patent claims" are all patent claims
 owned or controlled by the contributor, whether already acquired or
 hereafter acquired, that would be infringed by some manner, permitted
 by this License, of making, using, or selling its contributor version,
 but do not include claims that would be infringed only as a
 consequence of further modification of the contributor version.  For
 purposes of this definition, "control" includes the right to grant
 patent sublicenses in a manner consistent with the requirements of
 this License.
  Each contributor grants you a non-exclusive, worldwide, royalty-free
 patent license under the contributor's essential patent claims, to
 make, use, sell, offer to sale, import and otherwise run, modify and
 propagate the contents of its contributor version.
  In the following three paragraphs, a "patent license" is any express
 agreement or commitment, however denominated, not to enforce a patent
 (such as an express permission to practice a patent or covenant not to
 sue for patent infringement).  To "grant" such a patent license to a
 party means to make such an agreement or commitment not to enforce a
 patent against the party.
  If you convey a covered work, knowingly relying on a patent license,
 and the Corresponding Source of the work is not available for anyone
 to copy, free of charge and under the terms of this License, through a
 publicly available network server or other readily accessible means,
 then you must either (1) cause the Corresponding Source to be so
 available, or (2) arrange to deprive yourself of the benefit of the
 patent license for this particular work, or (3) arrange, in a manner
 consistent with the requirements of this License, to extend the patent
 license to downstream recipients.  "Knowingly relying" means you have
 actual knowledge that, but for the patent license, your conveying the
 covered work in a country, or your recipient's use of the covered work
 in a country, would infringe one or more identifiable patents in that
 country that you have reason to believe are valid.
  If, pursuant to or in connection with a single transaction or
 arrangement, you convey, or propagate by procuring conveyance of, a
 covered work, and grant a patent license to some of the parties
 receiving the covered work authorizing them to use, propagate, modify
 or convey a specific copy of the covered work, then the patent license
 you grant is automatically extended to all recipients of the covered
 work and works based on it.
  A patent license is "discriminatory" if it does not include within
 the scope of its coverage, prohibits the exercise of, or is
 conditioned on the non-exercise of one or more of the rights that are
 specifically granted under this License.  You may not convey a covered
 work if you are a party to an arrangement with a third party that is
 in the business of distributing software, under which you make payment
 to the third party based on the extent of your activity of conveying
 the work, and under which the third party grants, to any of the
 parties who would receive the covered work from you, a discriminatory
 patent license (a) in connection with copies of the covered work
 conveyed by you (or copies made from those copies), or (b) primarily
 for and in connection with specific products or compilations that
 contain the covered work, unless you entered into that arrangement,
 or that patent license was granted, prior to 28 March 2007.
  Nothing in this License shall be construed as excluding or limiting
 any implied license or other defenses to infringement that may
 otherwise be available to you under applicable patent law.
  12. No Surrender of Others' Freedom.
  If conditions are imposed on you (whether by court order, agreement or
 otherwise) that contradict the conditions of this License, they do not
 excuse you from the conditions of this License.  If you cannot convey a
 covered work so as to satisfy simultaneously your obligations under this
 License and any other pertinent obligations, then as a consequence you may
 not convey it at all.  For example, if you agree to terms that obligate you
 to collect a royalty for further conveying from those to whom you convey
 the Program, the only way you could satisfy both those terms and this
 License would be to refrain entirely from conveying the Program.
  13. Use with the GNU Affero General Public License.
  Notwithstanding any other provision of this License, you have
 permission to link or combine any covered work with a work licensed
 under version 3 of the GNU Affero General Public License into a single
 combined work, and to convey the resulting work.  The terms of this
 License will continue to apply to the part which is the covered work,
 but the special requirements of the GNU Affero General Public License,
 section 13, concerning interaction through a network will apply to the
 combination as such.
  14. Revised Versions of this License.
  The Free Software Foundation may publish revised and/or new versions of
 the GNU 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
 Program specifies that a certain numbered version of the GNU General
 Public License "or any later version" applies to it, you have the
 option of following the terms and conditions either of that numbered
 version or of any later version published by the Free Software
 Foundation.  If the Program does not specify a version number of the
 GNU General Public License, you may choose any version ever published
 by the Free Software Foundation.
  If the Program specifies that a proxy can decide which future
 versions of the GNU General Public License can be used, that proxy's
 public statement of acceptance of a version permanently authorizes you
 to choose that version for the Program.
  Later license versions may give you additional or different
 permissions.  However, no additional obligations are imposed on any
 author or copyright holder as a result of your choosing to follow a
 later version.
  15. Disclaimer of Warranty.
  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  16. Limitation of Liability.
  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
 SUCH DAMAGES.
  17. Interpretation of Sections 15 and 16.
  If the disclaimer of warranty and limitation of liability provided
 above cannot be given local legal effect according to their terms,
 reviewing courts shall apply local law that most closely approximates
 an absolute waiver of all civil liability in connection with the
 Program, unless a warranty or assumption of liability accompanies a
 copy of the Program in return for a fee.
                     END OF TERMS AND CONDITIONS
            How to Apply These Terms to Your New Programs
  If you develop a new program, and you want it to be of the greatest
 possible use to the public, the best way to achieve this is to make it
 free software which everyone can redistribute and change under these terms.
  To do so, attach the following notices to the program.  It is safest
 to attach them to the start of each source file to most effectively
 state the exclusion of warranty; and each file should have at least
 the "copyright" line and a pointer to where the full notice is found.
    <one line to give the program's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>
    This program is free software: you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation, either version 3 of the License, or
    (at your option) any later version.
    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU General Public License for more details.
    You should have received a copy of the GNU General Public License
    along with this program.  If not, see <https://www.gnu.org/licenses/>.
 Also add information on how to contact you by electronic and paper mail.
  If the program does terminal interaction, make it output a short
 notice like this when it starts in an interactive mode:
    <program>  Copyright (C) <year>  <name of author>
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.
 The hypothetical commands `show w' and `show c' should show the appropriate
 parts of the General Public License.  Of course, your program's commands
 might be different; for a GUI interface, you would use an "about box".
  You should also get your employer (if you work as a programmer) or school,
 if any, to sign a "copyright disclaimer" for the program, if necessary.
 For more information on this, and how to apply and follow the GNU GPL, see
 <https://www.gnu.org/licenses/>.
  The GNU General Public License does not permit incorporating your program
 into proprietary programs.  If your program is a subroutine library, you
 may consider it more useful to permit linking proprietary applications with
 the library.  If this is what you want to do, use the GNU Lesser General
 Public License instead of this License.  But first, please read
 <https://www.gnu.org/licenses/why-not-lgpl.html>.

      source, and configuration files.
      "Object" form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,
      and conversions to other media types.
      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).
      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.
      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent
      to the Licensor or its representatives, including but not limited to
      communication on electronic mailing lists, source code control systems,
      and issue tracking systems that are managed by, or on behalf of, the
      Licensor for the purpose of discussing and improving the Work, but
      excluding communication that is conspicuously marked or otherwise
      designated in writing by the copyright owner as "Not a Contribution."
      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.
   2. Grant of Copyright 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
      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.

 POSTGRES_DB=flux_panel
 POSTGRES_USER=flux_panel
 POSTGRES_PASSWORD=replace_with_strong_password
 ```
 > 📌 使用安装脚本部署时，`POSTGRES_PASSWORD` 会自动随机生成并写入 `.env`。
 2) 启动服务：
 ```bash
 docker compose up -d
 ```
 3) 如果你想继续使用 SQLite，保留 `DB_TYPE=sqlite`（或不设置 `DB_TYPE`）即可。
 #### 从 SQLite 迁移到 PostgreSQL
 如果你是通过 `panel_install.sh` 安装面板，推荐直接使用脚本菜单一键迁移：
 ```bash
 ./panel_install.sh
 # 选择 4. 迁移到 PostgreSQL
 ```
 脚本会自动完成 SQLite 备份、PostgreSQL 启动、`pgloader` 导入、`.env` 中 `DB_TYPE`/`DATABASE_URL` 更新，并重启服务。
 如果你希望手动迁移，以下示例基于 Docker Volume `sqlite_data`（项目默认配置）与 `pgloader`：
 1) 停止服务并备份 SQLite 数据：
 ```bash
 docker compose down
 docker run --rm -v sqlite_data:/data -v "$(pwd)":/backup alpine sh -c "cp /data/gost.db /backup/gost.db.bak"
 ```
 2) 仅启动 PostgreSQL：
 ```bash
 docker compose up -d postgres
 ```
 3) 使用 `pgloader` 迁移：
 ```bash
 source .env
 docker run --rm --network gost-network -v sqlite_data:/sqlite dimitri/pgloader:latest pgloader /sqlite/gost.db "postgresql://${POSTGRES_USER}:${POSTGRES_PASSWORD}@postgres:5432/${POSTGRES_DB}"
 ```
 4) 切换后端到 PostgreSQL 并启动：
 ```bash
 source .env
 export DB_TYPE=postgres
 export DATABASE_URL="postgresql://${POSTGRES_USER}:${POSTGRES_PASSWORD}@postgres:5432/${POSTGRES_DB}?sslmode=disable"
 docker compose up -d
 ```
 5) 迁移完成后，登录面板检查用户、隧道、转发、节点数据是否正确。

 ### Q5: IPv6 无法使用？
 **A**: 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 `/etc/docker/daemon.json` 配置，确保 `ipv6: true` 且分配了正确的 `fixed-cidr-v6` 子网。
 ### Q6: 如何切换到 PostgreSQL？
 **A**: 在 `.env` 文件中设置 `DB_TYPE=postgres`，并让 `DATABASE_URL` 与 `POSTGRES_*` 保持一致，然后执行 `docker compose up -d` 重启服务即可。使用安装脚本部署时，`POSTGRES_PASSWORD` 会自动随机生成并写入 `.env`。详见 [PostgreSQL 数据库指南](./postgresql.md)。
 ### Q7: 从 SQLite 迁移到 PostgreSQL 后数据丢失？
 **A**:
 1. 确认迁移前已备份 SQLite 文件（`gost.db.bak`）。
 2. 确认 `pgloader` 命令执行成功，检查其输出是否有报错。
 3. 确认 `.env` 中 `DATABASE_URL` 的密码与 `POSTGRES_PASSWORD` 一致。
 4. 详细迁移步骤参考 [PostgreSQL 数据库指南 - 从 SQLite 迁移](./postgresql.md)。
 ### Q8: PostgreSQL 容器启动失败？
 **A**:
 1. 检查 `POSTGRES_PASSWORD` 是否已设置（不能为空）。
 2. 查看容器日志：`docker logs flux-panel-postgres`。
 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：`docker volume rm postgres_data`。

 ## 三、Caddy 反向代理（可选）
 如果需要通过域名访问面板并自动获取 HTTPS 证书，可以使用 Caddy 作为反向代理。
 ### 1. 安装 Caddy
 ```bash
 # Debian / Ubuntu
 sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https curl
 curl -1sLf 'https://dl.cloudflare.com/content/v1/e2qwFJ2fRP2b2q/stable/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
 curl -1sLf 'https://dl.cloudflare.com/content/v1/e2qwFJ2fRP2b2q/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
 sudo apt update
 sudo apt install caddy
 ```
 其他系统请参考 [Caddy 官方安装文档](https://caddyserver.com/docs/install)。
 ### 2. 配置 Caddyfile
 编辑 Caddy 配置文件：
 ```bash
 sudo nano /etc/caddy/Caddyfile
 ```
 #### 面板域名配置
 将 `panel.example.com` 替换为你自己的域名：
 ```caddyfile
 panel.example.com {
    reverse_proxy localhost:6366
 }
 ```
 Caddy 会自动为域名申请和续期 HTTPS 证书，无需额外配置。
 ### 3. 重启 Caddy
 ```bash
 sudo systemctl restart caddy
 ```
 ### 4. 注意事项
 - 确保域名已正确解析到服务器 IP。
 - 确保服务器防火墙放行了 **80** 和 **443** 端口（Caddy 自动申请证书需要）。
 - 使用 Caddy 反向代理后，可以在 `.env` 中将前端端口改为仅监听本地，避免直接暴露：
  ```
  FRONTEND_PORT=127.0.0.1:6366

 # PostgreSQL 数据库指南
 FLVX 默认使用 SQLite 作为数据库，同时也内置了对 PostgreSQL 的完整支持。本文档介绍如何使用 PostgreSQL 部署面板、从 SQLite 迁移以及日常维护。
 ## 一、SQLite 与 PostgreSQL 对比
 | 特性 | SQLite | PostgreSQL |
 |------|--------|------------|
 | **部署复杂度** | 零配置，开箱即用 | 需要额外的数据库服务 |
 | **并发性能** | 适合小规模单机使用 | 支持高并发读写 |
 | **数据规模** | 适合中小规模数据 | 适合大规模数据 |
 | **备份与恢复** | 直接复制文件 | 支持逻辑备份与物理备份 |
 | **高可用** | 不支持 | 支持主从复制、流复制 |
 **建议**：如果你只是个人使用或小团队使用，SQLite 完全够用。如果节点多，推荐使用 PostgreSQL。
 ---
 ## 二、环境变量说明
 以下环境变量用于配置数据库连接，在 `.env` 文件或 Docker Compose `environment` 中设置。
 ### 后端服务 (backend) 使用
 | 变量名 | 说明 | 默认值 | 示例 |
 |--------|------|--------|------|
 | `DB_TYPE` | 数据库类型，`sqlite` 或 `postgres` | `sqlite` | `postgres` |
 | `DATABASE_URL` | PostgreSQL 连接字符串（仅 `DB_TYPE=postgres` 时必填） | 空 | `postgres://flux_panel:密码@postgres:5432/flux_panel?sslmode=disable` |
 | `DB_PATH` | SQLite 数据库文件路径（仅 `DB_TYPE=sqlite` 时使用） | `/app/data/gost.db` | `/app/data/gost.db` |
 ### PostgreSQL 容器使用
 | 变量名 | 说明 | 默认值 |
 |--------|------|--------|
 | `POSTGRES_DB` | 数据库名称 | `flux_panel` |
 | `POSTGRES_USER` | 数据库用户名 | `flux_panel` |
 | `POSTGRES_PASSWORD` | 数据库密码 | `flux_panel_change_me` |
 > ⚠️ **安全提示**：生产环境中请务必修改 `POSTGRES_PASSWORD` 为强密码，不要使用默认值！
 ---
 ## 三、全新部署（Docker Compose + PostgreSQL）
 安装脚本会根据环境自动下载对应的 Compose 配置并保存为 `docker-compose.yml`。默认使用 SQLite，只需配置环境变量即可切换到 PostgreSQL。
 ### 1. 创建 `.env` 文件
 在 `docker-compose` 同目录创建 `.env` 文件：
 ```bash
 # 基础配置
 JWT_SECRET=替换为你的密钥
 BACKEND_PORT=6365
 FRONTEND_PORT=6366
 # PostgreSQL 配置
 DB_TYPE=postgres
 DATABASE_URL=postgres://flux_panel:替换为强密码@postgres:5432/flux_panel?sslmode=disable
 POSTGRES_DB=flux_panel
 POSTGRES_USER=flux_panel
 POSTGRES_PASSWORD=替换为强密码
 ```
 > ⚠️ `DATABASE_URL` 中的密码必须与 `POSTGRES_PASSWORD` 保持一致。
 ### 2. 启动服务
 ```bash
 docker compose up -d
 ```
 ### 3. 验证
 ```bash
 # 检查所有容器是否正常运行
 docker ps
 # 查看后端日志，确认连接 PostgreSQL 成功
 docker logs flux-panel-backend
 # 查看 PostgreSQL 容器状态
 docker logs flux-panel-postgres
 ```
 ---
 ## 四、从 SQLite 迁移到 PostgreSQL
 如果你已经在使用 SQLite 并且希望迁移到 PostgreSQL，请按照以下步骤操作。
 ### 快速方式：脚本菜单一键迁移（推荐）
 如果你是通过安装脚本部署面板，可直接执行：
 ```bash
 ./panel_install.sh
 # 选择 4. 迁移到 PostgreSQL
 ```
 脚本会自动完成以下操作：
 - 备份 SQLite 数据到当前目录（`gost.db.bak`）
 - 启动并等待 PostgreSQL 健康检查通过
 - 使用 `pgloader` 导入 SQLite 数据
 - 自动写入 `.env` 的 `DB_TYPE=postgres` 与 `DATABASE_URL`
 - 重启服务并等待后端健康检查
 ### 手动方式：按步骤迁移
 ### 1. 备份 SQLite 数据
 ```bash
 # 停止所有服务
 docker compose down
 # 备份 SQLite 数据文件到当前目录
 docker run --rm -v sqlite_data:/data -v "$(pwd)":/backup alpine sh -c "cp /data/gost.db /backup/gost.db.bak"
 ```
 ### 2. 配置 PostgreSQL 环境变量
 在 `.env` 文件中添加 PostgreSQL 配置（参考上方"环境变量说明"）。
 ### 3. 仅启动 PostgreSQL
 ```bash
 docker compose up -d postgres
 ```
 等待 PostgreSQL 完全就绪：
 ```bash
 # 检查 PostgreSQL 健康状态
 docker inspect --format='{{.State.Health.Status}}' flux-panel-postgres
 # 输出 "healthy" 表示就绪
 ```
 ### 4. 使用 pgloader 迁移数据
 ```bash
 source .env
 docker run --rm \
  --network gost-network \
  -v sqlite_data:/sqlite \
  dimitri/pgloader:latest \
  pgloader /sqlite/gost.db "postgresql://${POSTGRES_USER}:${POSTGRES_PASSWORD}@postgres:5432/${POSTGRES_DB}"
 ```
 > 📌 建议直接从 `.env` 读取 `POSTGRES_USER`、`POSTGRES_PASSWORD`、`POSTGRES_DB`，避免手填密码导致认证失败。
 ### 5. 启动全部服务
 ```bash
 source .env
 export DB_TYPE=postgres
 export DATABASE_URL="postgresql://${POSTGRES_USER}:${POSTGRES_PASSWORD}@postgres:5432/${POSTGRES_DB}?sslmode=disable"
 docker compose up -d
 ```
 ### 6. 验证迁移
 登录面板后，检查以下数据是否完整：
 - 用户列表和权限
 - 节点信息和状态
 - 隧道配置
 - 转发规则
 - 流量统计数据
 ---
 ## 五、独立 PostgreSQL（非 Docker）
 如果你不想使用 Docker Compose 中自带的 PostgreSQL 容器，也可以连接外部的 PostgreSQL 实例。
 ### 1. 准备 PostgreSQL
 在目标 PostgreSQL 服务器上创建数据库和用户：
 ```sql
 CREATE USER flux_panel WITH PASSWORD '你的强密码';
 CREATE DATABASE flux_panel OWNER flux_panel;
 ```
 ### 2. 配置连接
 修改 `.env` 文件，将 `DATABASE_URL` 指向外部 PostgreSQL：
 ```bash
 DB_TYPE=postgres
 DATABASE_URL=postgres://flux_panel:你的强密码@数据库地址:5432/flux_panel?sslmode=disable
 ```
 > 📌 如果 PostgreSQL 在远程服务器且启用了 SSL，请将 `sslmode=disable` 改为 `sslmode=require` 或 `sslmode=verify-full`。
 ### 3. 停用内置 PostgreSQL 容器（可选）
 如果使用外部 PostgreSQL，可以在启动时不启动内置的 postgres 服务：
 ```bash
 docker compose up -d backend frontend
 ```
 ---
 ## 六、数据备份与恢复
 ### 逻辑备份（pg_dump）
 ```bash
 # 备份（在 Docker 环境下）
 docker exec flux-panel-postgres pg_dump -U flux_panel flux_panel > backup_$(date +%Y%m%d_%H%M%S).sql
 # 恢复
 docker exec -i flux-panel-postgres psql -U flux_panel flux_panel < backup_20260101_120000.sql
 ```
 ### 定时备份（cron）
 创建备份脚本 `/opt/flvx/backup.sh`：
 ```bash
 #!/bin/bash
 BACKUP_DIR="/opt/flvx/backups"
 mkdir -p "$BACKUP_DIR"
 docker exec flux-panel-postgres pg_dump -U flux_panel flux_panel | gzip > "$BACKUP_DIR/flvx_$(date +%Y%m%d_%H%M%S).sql.gz"
 # 清理 30 天前的备份
 find "$BACKUP_DIR" -name "flvx_*.sql.gz" -mtime +30 -delete
 ```
 添加 cron 任务（每天凌晨 3 点执行）：
 ```bash
 chmod +x /opt/flvx/backup.sh
 echo "0 3 * * * /opt/flvx/backup.sh" | crontab -
 ```
 ---
 ## 七、常见问题
 ### Q: 切换到 PostgreSQL 后启动失败，提示连接被拒绝？
 **A**: 
 1. 确认 PostgreSQL 容器已启动并处于 `healthy` 状态：`docker ps`。
 2. 确认 `DATABASE_URL` 中的主机名、端口、用户名、密码正确。
 3. 在 Docker Compose 环境下，主机名应为 `postgres`（服务名），而非 `localhost`。
 ### Q: pgloader 迁移时报错？
 **A**: 
 1. 确认 PostgreSQL 容器已完全就绪（状态为 `healthy`）。
 2. 确认 `--network gost-network` 参数正确，使 pgloader 容器与 PostgreSQL 在同一网络中。
 3. 如果数据库已有表结构，pgloader 可能会报冲突。可以先清空目标数据库后重试。
 ### Q: 如何查看当前使用的数据库类型？
 **A**: 查看后端容器的 `DB_TYPE` 环境变量：
 ```bash
 docker exec flux-panel-backend printenv DB_TYPE
 ```
 ### Q: 可以同时使用 SQLite 和 PostgreSQL 吗？
 **A**: 不可以。`DB_TYPE` 只能设置为 `sqlite` 或 `postgres` 之一。后端启动时根据此配置连接对应的数据库。
 ### Q: PostgreSQL 数据存储在哪里？
 **A**: 在 Docker Compose 部署中，PostgreSQL 数据存储在名为 `postgres_data` 的 Docker Volume 中。可以通过以下命令查看：
 ```bash
 docker volume inspect postgres_data
 ```

 ## CONVENTIONS
- **GORM ORM**: Uses GORM with `glebarez/sqlite` (CGO-free) and `gorm.io/driver/postgres`.
+- **No ORM**: Uses raw SQL with `database/sql` and `modernc.org/sqlite`.
 - **AutoMigrate**: Schema created at startup via `autoMigrateAll()` — no hand-written DDL.
 - **TableName()**: All models define explicit `TableName()` returning singular snake_case names.
 - **Repository Pattern**: Handlers never access `*gorm.DB` directly — all queries go through `repo.Repository` methods.
 - **Standard Lib**: Uses `net/http` for routing (Go 1.22+ patterns).
 - **Auth**: Expects raw JWT in `Authorization` header (no `Bearer` prefix).
 - **API Envelope**: All responses use `response.R{code, msg, data, ts}` structure.
 - **Config**: Loaded from environment variables (see `cmd/paneld/main.go`).
 - **SQLite Constraints**: `MaxOpenConns(1)`, WAL mode, busy_timeout=5000.
 - **PostgreSQL**: Supported via `DB_TYPE=postgres` and `DATABASE_URL` env vars.
 ## ANTI-PATTERNS
 - **DO NOT** let handlers call `repo.DB()` directly — add a Repository method instead.
 - **DO NOT CHANGE** handler signatures without updating `router.go`.
 - **DO NOT** use `type:jsonb` or `type:serial` in GORM tags (SQLite incompatible).
 - **DO NOT** omit `TableName()` on new models — GORM pluralizes by default.

 # 数据库 GORM ORM 迁移计划
 **创建时间:** 2026-02-15
 **更新时间:** 2026-02-17 (实施：完成 P1 + P2 + P3 + P5(Repo 查询层 + schema 收尾) + 测试/构建收尾)
 **分支:** main (commit e5e22ba)
 **状态:** 基本完成（保留 4 处 PG 序列修复 DDL `Exec`）
 ---
 ## 一、现状分析
 ### 1.1 迁移前架构 (已归档)
 项目原使用 `database/sql` + 手写 raw SQL，通过 `internal/store/db.go` 中的运行时 SQL 重写层实现 SQLite/PostgreSQL 双数据库兼容。
 | 组件 | 行数 | 角色 | 当前状态 |
 |------|------|------|----------|
 | `store/db.go` | ~520 | SQL 方言重写层 | **已删除** |
 | `store/sqlite/repository.go` | ~3118 | Repository 查询方法 | **已重写为 store/repo/** |
 | `handler/mutations.go` | ~3748 | Handler 内直接写 raw SQL | **已迁移到 repo（生产 SQL=0）** |
 | `handler/handler.go` | ~1283 | 部分方法用 `repo.DB()` | **大部分已迁移** |
 | `handler/federation.go` | ~若干 | Federation 相关 SQL | **已迁移到 repo** |
 | `handler/control_plane.go` | ~若干 | 控制面相关 SQL | **已迁移到 repo** |
 | `handler/flow_policy.go` | ~若干 | 流量策略相关 SQL | **已迁移到 repo** |
 | `handler/jobs.go` | ~若干 | 后台任务相关 SQL | **已迁移到 repo** |
 | `store/postgres/` | 目录 | PostgreSQL 专用 schema/data | **已删除** |
 ### 1.2 痛点 (迁移目标)
 1. ~~**双 Schema 维护**~~：已通过 AutoMigrate 解决
 2. ~~**SQL 重写层复杂**~~：db.go 已删除
 3. ~~**handler 直接写 SQL**~~：`mutations.go` 生产路径 `tx.Exec`/`tx.Raw` 已清零（测试代码除外）
 4. ~~**无类型安全**~~：repo 业务查询已 GORM 化；剩余 4 处为 PG 序列修复 DDL `Exec`（设计保留）
 5. ~~**模型定义分散**~~：已集中到 model/model.go
 ---
 ## 二、方案：引入 GORM ORM（全面重写）
 ### 2.1 方案变更说明
 原计划为 **方案 D（扩展现有 DDL 重写层）**，现变更为 **方案 A（GORM 全面重写）**。
 ### 2.2 选择 GORM 的理由
 1. Go 生态最成熟的 ORM，社区庞大，文档完善
 2. 原生支持 SQLite + PostgreSQL 双数据库，自动处理方言差异
 3. AutoMigrate 消除双 schema 维护，自动处理 AUTOINCREMENT ↔ SERIAL 等
 4. 类型安全的模型定义，编译期检查字段映射
 5. 内置事务管理（closure pattern 自动 rollback/commit）
 6. 自动处理 `"user"` 保留字引号
 ### 2.3 GORM 驱动选择
 | 数据库 | 驱动 | 包 | 备注 |
 |--------|------|-----|------|
 | SQLite | modernc.org/sqlite (CGO-free) | `github.com/glebarez/sqlite` | 纯 Go，无需 CGO |
 | PostgreSQL | pgx/v5 | `gorm.io/driver/postgres` | 默认使用 pgx |
 > **注意**：标准 `gorm.io/driver/sqlite` 依赖 CGO，必须使用 `glebarez/sqlite` 包装器。
 ### 2.4 核心设计原则
 1. **Model 集中定义**：所有 GORM Model 在 `internal/store/model/` 包中
 2. **Repository 模式保留**：Repository struct 持有 `*gorm.DB`，对外方法签名尽量不变
 3. **Handler 不直接操作 DB**：所有数据库操作必须封装在 Repository 方法中
 4. **AutoMigrate 替代 schema.sql**：启动时自动迁移，不再维护手写 DDL
 5. **保留 PG 序列修复**：pgloader 迁移场景仍需 `ensurePostgresIDDefaults()`
 6. **Package 重命名**：`store/sqlite` → `store/repo`
 ---
 ## 三、Model 设计
 ### 3.1 GORM 类型映射
 | Go 类型 | GORM 行为 | PostgreSQL | SQLite |
 |---------|-----------|------------|--------|
 | `int64` + `primaryKey` | 自增主键 | `bigserial` | `INTEGER PRIMARY KEY AUTOINCREMENT` |
 | `int64` | 64位整数 | `bigint` | `integer` (SQLite 自动 64位) |
 | `int` | 整数 | `integer` | `integer` |
 | `float64` | 浮点 | `double precision` | `real` |
 | `string` + `size:100` | 变长字符 | `varchar(100)` | `varchar(100)` |
 | `string` (无 size) | 文本 | `text` | `text` |
 | `sql.NullInt64` | 可空整数 | `bigint NULL` | `integer NULL` |
 | `sql.NullString` | 可空文本 | `text NULL` | `text NULL` |
 ### 3.2 表清单（21 张表）
 | 表名 | Model | 特殊处理 |
 |------|-------|----------|
 | `user` | `User` | `TableName()` 返回 `"user"` (PG 保留字) |
 | `forward` | `Forward` | |
 | `forward_port` | `ForwardPort` | |
 | `node` | `Node` | |
 | `speed_limit` | `SpeedLimit` | |
 | `statistics_flow` | `StatisticsFlow` | |
 | `tunnel` | `Tunnel` | |
 | `chain_tunnel` | `ChainTunnel` | |
 | `user_tunnel` | `UserTunnel` | 复合唯一索引 (user_id, tunnel_id) |
 | `tunnel_group` | `TunnelGroup` | |
 | `user_group` | `UserGroup` | |
 | `tunnel_group_tunnel` | `TunnelGroupTunnel` | 复合唯一索引 |
 | `user_group_user` | `UserGroupUser` | 复合唯一索引 |
 | `group_permission` | `GroupPermission` | 复合唯一索引 |
 | `group_permission_grant` | `GroupPermissionGrant` | 复合唯一索引 |
 | `vite_config` | `ViteConfig` | name 唯一 |
 | `peer_share` | `PeerShare` | token 唯一 |
 | `peer_share_runtime` | `PeerShareRuntime` | reservation_id, resource_key 唯一 |
 | `federation_tunnel_binding` | `FederationTunnelBinding` | 复合唯一索引 + resource_key 唯一 |
 | `announcement` | `Announcement` | |
 | `schema_version` | `SchemaVersion` | |
 ---
 ## 四、详细实施步骤
 ### 阶段 1：基础设施 — 添加依赖 + 定义 Model ✅ 已完成

 | 2.2 | 重写 `Open()` — 用 `glebarez/sqlite` 打开 SQLite | repository.go | ✅ |
 | 2.3 | 重写 `OpenPostgres()` — 用 `gorm.io/driver/postgres` 打开 PG | repository.go | ✅ |
 | 2.4 | 用 `db.AutoMigrate()` 替代 `bootstrapSchema()` | repository.go | ✅ |

 | 2.8 | `DB()` 方法返回 `*gorm.DB` | repository.go | ✅ |
 | 2.9 | SQLite 连接池设置 `MaxOpenConns(1)` 防锁 | repository.go | ✅ |
 ### 阶段 3：重写 repository 查询方法 ⚠️ ~97% 完成
 将所有 raw SQL 查询替换为 GORM 链式调用。
 > **2026-02-16 审计**：基础 CRUD 查询已 GORM 化，但 mutation、JOIN 查询、import/export 仍大量使用 raw SQL。
 > **2026-02-17 更新**：已完成 `repository_mutations.go`、Import、以及 `repository_federation/control/flow` 查询层 GORM 化；`repository.go` 中 Raw 已清零，当前仅保留 4 处 PG 序列修复 DDL `Exec`。
 | 步骤 | 任务 | 方法数 | 状态 |
 |------|------|--------|------|
 | 3.1 | 用户查询：GetUserByUsername, GetUserByID, UsernameExists* 等 | ~5 | ✅ |
 | 3.2 | 配置查询：GetConfigByName, ListConfigs, UpsertConfig | ~3 | ✅ |
 | 3.3 | 公告查询：GetAnnouncement, UpsertAnnouncement | ~2 | ✅ |
 | 3.4 | 节点查询：GetNodeBy*, ListNodes, UpdateNode* | ~6 | ✅ |
 | 3.5 | 隧道查询：ListTunnels, ListTunnelGroups 等 (含 chain_tunnel 关联) | ~5 | ✅ |
 | 3.6 | 转发查询：ListForwards, resolveForwardIngress | ~3 | ✅ |
 | 3.7 | 用户隧道：GetUserPackageTunnels, GetUserPackageForwards | ~3 | ✅ |
 | 3.8 | 统计/限速：GetStatisticsFlows, ListSpeedLimits, AddFlow | ~4 | ✅ |
 | 3.9 | 分组查询：ListUserGroups, ListGroupPermissions 等 | ~4 | ✅ |
 | 3.10 | PeerShare 全部方法 (CRUD + Runtime) | ~15 | ✅ |
 | 3.11 | FederationTunnelBinding 全部方法 | ~4 | ✅ (Upsert 用 clause.OnConflict) |

 | **3.16** | **repository_control.go 复杂查询** | **~5** | **✅ 已全部改为 GORM 链式调用** |
 | **3.17** | **repository_flow.go 查询方法** | **~5** | **✅ 已全部改为 GORM 链式调用** |
 | **3.18** | **Jobs 查询方法 (repository.go 尾部)** | **~8** | **✅ 已 GORM 化** |
 ### 阶段 4：消除 handler 中直接 SQL — 提取为 Repository 方法 ✅ 已完成
 > **2026-02-16 审计**：handler 中的 SQL 已大部分提取到 repo 层，但这些 repo 方法本身仍使用 raw SQL（见阶段 3）。
 > **2026-02-17 更新**：`mutations.go` 直接 `tx.Exec`/`tx.Raw` 已从 27 处降至 0 处（生产代码），详见 §9.4。
 mutations.go 和其他 handler 文件中大量直接操作 `h.repo.DB()` 执行 raw SQL，需要：
 1. 将 SQL 逻辑提取为 Repository 方法
 2. Handler 只调用 Repository 方法
 | 步骤 | 任务 | 文件 | 状态 |
 |------|------|------|------|
 | 4.1 | 用户 CRUD：userCreate, userUpdate, userDelete, userResetFlow | mutations.go | ✅ 已提取到 repo 方法 |
 | 4.2 | 节点 CRUD：nodeCreate, nodeUpdate, nodeDelete, nodeBatch* | mutations.go | ✅ 已提取到 repo 方法 |
 | 4.3 | 隧道 CRUD：tunnelCreate, tunnelUpdate, tunnelDelete, tunnelBatch* | mutations.go | ✅ tunnelCreate/Update 的 SQL 已下沉 repo |
 | 4.4 | 转发 CRUD：forwardCreate, forwardUpdate, forwardDelete, forwardBatch* | mutations.go | ✅ 已提取到 repo (CreateForwardTx 等) |
 | 4.5 | 限速 CRUD：speedLimitCreate, speedLimitUpdate, speedLimitDelete | mutations.go | ✅ 已提取到 repo 方法 |
 | 4.6 | 分组 CRUD：所有 group* 方法 | mutations.go | ✅ 成员同步/权限管理 SQL 已下沉 repo |
 | 4.7 | 用户隧道：userTunnelAssign, userTunnelRemove, userTunnelUpdate | mutations.go | ✅ 已提取到 repo 方法 |
 | 4.8 | handler.go 中的直接 SQL (openAPISubStore 等) | handler.go | ✅ 已迁移（含 nil 检查清理） |
 | 4.9 | federation.go 中的 raw SQL | federation.go | ✅ 已提取到 repo_federation.go |
 | 4.10 | control_plane.go 中的 raw SQL | control_plane.go | ✅ 已提取到 repo_control.go |
 | 4.11 | flow_policy.go 中的 raw SQL | flow_policy.go | ✅ 已提取到 repo_flow.go |
 | 4.12 | jobs.go 中的 raw SQL | jobs.go | ✅ 已提取到 repo 方法（含 nil 检查清理） |
 ### 阶段 5：清理旧代码 ✅ 已完成
 | 步骤 | 任务 | 文件 | 状态 |
 |------|------|------|------|
 | 5.1 | 删除 `internal/store/postgres/` 整个目录 | 目录删除 | ✅ |
 | 5.2 | 删除 `internal/store/sqlite/sql/` 目录 | 目录删除 | ✅ |
 | 5.3 | 删除 `internal/store/db.go` SQL 重写层 | 文件删除 | ✅ |
 | 5.4 | 删除 `internal/store/db_test.go` | 文件删除 | ✅ |
 | 5.5 | 清理 repository.go 中不再需要的 embed 指令 | 清理 | ✅ |
 ### 阶段 6：Package 重命名 ✅ 已完成
 | 步骤 | 任务 | 文件 | 状态 |
 |------|------|------|------|
 | 6.1 | `internal/store/sqlite/` → `internal/store/repo/` | 目录重命名 | ✅ |
 | 6.2 | 更新所有 import 路径：`store/sqlite` → `store/repo` (13处) | 全局替换 | ✅ |
 ### 阶段 7：测试 + 验证 ⚠️ 部分完成
 | 步骤 | 任务 | 状态 |
 |------|------|------|
 | 7.1 | 更新所有现有测试适配 GORM | ✅ 测试已适配 (使用 repo.DB() 做数据准备) |
 | 7.2 | `go test ./...` 全部通过 | ✅ 已通过（含 `internal/http/handler`、`tests/contract`） |
 | 7.3 | `make build` 构建成功 | ✅ 已通过 |
 ### 阶段 8：文档更新 ✅ 已完成
 | 步骤 | 任务 | 文件 | 状态 |
 |------|------|------|------|
 | 8.1 | 更新 `go-backend/AGENTS.md` — 移除 "DO NOT USE ORM"，记录 GORM 规范 | AGENTS.md | ✅ |
 | 8.2 | 更新根 `AGENTS.md` | AGENTS.md | ✅ |
 | 8.3 | 更新 `handler/AGENTS.md` | AGENTS.md | ✅ |
 ---
 ## 五、GORM 使用规范
 ### 5.1 查询模式
 ```go
 // 单条查询 - 未找到返回 nil, nil (保持现有语义)
 var user model.User
 err := r.db.Where("id = ?", id).First(&user).Error
 if errors.Is(err, gorm.ErrRecordNotFound) {
    return nil, nil
 }
 // 列表查询
 var users []model.User
 err := r.db.Where("role_id != ?", 0).Order("id ASC").Find(&users).Error
 // 创建
 err := r.db.Create(&user).Error
 // 更新 (部分字段)
 err := r.db.Model(&model.User{}).Where("id = ?", id).Updates(map[string]interface{}{
    "user": username, "flow": flow, "updated_time": now,
 }).Error
 // 事务 (closure pattern - 自动 rollback/commit)
 err := r.db.Transaction(func(tx *gorm.DB) error {
    if err := tx.Where("user_id = ?", id).Delete(&model.Forward{}).Error; err != nil {
        return err
    }
    return tx.Where("id = ?", id).Delete(&model.User{}).Error
 })
 // 原生 SQL (仅用于复杂查询和 PG 特有操作)
 r.db.Exec("SELECT setval(?::regclass, ?, ?)", seqRef, maxID, true)
 ```
 ### 5.2 关键注意事项
 1. **user 保留字**：通过 `TableName()` 返回 `"user"`，GORM 自动处理引号
 2. **SQLite MaxOpenConns**：必须设为 1 防止 "database locked"
 3. **SQLite WAL 模式**：DSN 中配置 `_pragma=journal_mode(WAL)`
 4. **不要用 `type:jsonb`**：SQLite 不支持，用 `serializer:json`
 5. **不要用 `type:serial`**：让 GORM 从 `primaryKey` 自动推断
 6. **AutoMigrate 在 SQLite 中使用 copy-swap-drop**：大表慎用
 ---
 ## 六、影响范围
 ### 需要修改的文件
 | 文件 | 修改类型 | 描述 | 当前状态 |
 |------|----------|------|----------|
 | `go.mod` / `go.sum` | 修改 | 添加 GORM + 驱动依赖 | ✅ |
 | `internal/store/model/model.go` | **新增** | 全部 21 个 GORM Model | ✅ |
 | `internal/store/repo/repository.go` | **重写** | 全部查询 GORM 化 | ⚠️ 业务查询已 GORM；仅剩 PG 序列修复 DDL `Exec` 4 处 |

 | `internal/store/postgres/` | **删除** | 不再需要 | ✅ |
 | `internal/store/db.go` | **删除** | GORM 自动处理方言 | ✅ |
 | `internal/store/db_test.go` | **删除** | 旧重写层测试 | ✅ |
 | `internal/store/sqlite/sql/` | **删除** | AutoMigrate 替代 | ✅ |
 | `tests/contract/*.go` | 修改 | 适配 GORM | ✅ |
 | `AGENTS.md` (3处) | 更新 | 反映新架构 | ✅ |
 ### 不需要修改的文件
 - `internal/http/router.go` — 路由不变
 - `internal/config/config.go` — 配置不变
 - `internal/auth/` — 认证不变
 - `internal/security/` — 加密不变
 - `internal/http/middleware/` — 中间件不变
 - `internal/http/response/` — 响应格式不变
 - `Dockerfile`, `Makefile` — 构建不变
 ---
 ## 七、风险与缓解
 | 风险 | 可能性 | 影响 | 缓解措施 |
 |------|--------|------|----------|
 | GORM AutoMigrate SQLite/PG 行为差异 | 中 | 高 | 先写 Model 验证双数据库 AutoMigrate |
 | handler 中散落 raw SQL 遗漏 | 中 | 高 | 全局搜索 `.Exec(`, `.Query(`, `.QueryRow(` |
 | 事务语义变化 | 低 | 中 | 逐方法对比旧代码事务边界 |
 | 大量代码变更导致回归 | 高 | 高 | 分阶段提交，每阶段 `go test` |
 | GORM 性能开销 | 低 | 低 | 此场景下可忽略 |
 | SQLite "database locked" | 中 | 高 | `MaxOpenConns(1)` + WAL 模式 |
 ---
 ## 八、迁移顺序原则
 1. **先 Model 后查询**：确保 AutoMigrate 双数据库通过
 2. **先 Repository 后 Handler**：Handler 依赖 Repository
 3. **先核心后边缘**：User → Node → Tunnel → Forward → 分组 → Federation
 4. **每步编译**：每完成一组方法确保 `go build ./...` 通过
 5. **最后清理**：全部重写完成后再删除旧代码和重命名 package

 ## 九、2026-02-16 审计发现 + 2026-02-17 进展记录
 ### 9.1 总体完成度
 | 指标 | 数值 |
 |------|------|
 | 阶段完成数 | 7/8 完成 (1, 2, 4, 5, 6, 7, 8)，1/8 部分完成 (3) |
 | GORM 链式调用 | ~226 处 |
 | Raw SQL 调用 (`.Exec`/`.Raw`+`.Scan`) | 4 处（生产代码） |
 | GORM 占比 | ~98% |
 | Handler 内 `tx.Exec`/`tx.Raw` | 0 处（生产代码） |
 | `last_insert_rowid()` 生产代码 | 0 处（已消灭） |
 ### 9.2 ✅ P0：`last_insert_rowid()`（生产代码）已清零
 `last_insert_rowid()` 已从生产路径移除，创建主键统一改为 `Create(&model)` 自动回填 ID，
 确保 SQLite / PostgreSQL 双数据库行为一致。
 > 备注：测试代码中的历史 SQL 兼容性用例可在后续测试清理阶段单独处理。
 ### 9.3 ✅ P1：`repository_mutations.go` 已全量 GORM 化
 本次已完成 `repository_mutations.go` 的集中清理：
 1. User / Node / Tunnel / Forward / UserTunnel / SpeedLimit / Group / Permission 全部 mutation 方法改为 GORM 链式调用。
 2. 事务内级联删除统一为 `tx.Where(...).Delete(&Model{})` 模式。
 3. `ON CONFLICT DO NOTHING` 统一替换为 `Clauses(clause.OnConflict{DoNothing: true})`。
 4. 保留原有调用语义（含 `sql.ErrNoRows` 行为兼容）并完成 `go build ./...` 验证。
 > 当前 `repository_mutations.go` 中生产代码 `.Raw(`/`.Exec(` 调用已降为 0。
 ### 9.4 ✅ P2：Handler `mutations.go` 直接 SQL 已清零
 2026-02-17 本轮静态扫描结果：`mutations.go` **0 处** `tx.Exec`/`tx.Raw`（生产代码）。
 本轮完成下沉到 repo 的逻辑：
 - `tunnelUpdate` 中 `UPDATE tunnel` + `DELETE chain_tunnel`
 - `isRemoteNodeTx` 查询
 - `pickNodePortTx` 的 node/chain_tunnel/forward_port 端口占用查询
 - `replaceTunnelChainsTx` 的 chain_tunnel 写入
 - 分组成员同步（`tunnel_group_tunnel` / `user_group_user`）
 - 权限删除与 grant 回收（`group_permission` / `group_permission_grant` / `user_tunnel`）
 - federation 绑定替换（`federation_tunnel_binding`）
 ### 9.5 ✅ P3（部分）：已移除 `QueryInt64List` / `QueryPairs` SQL 透传
 - `repository_mutations.go` 中两个 SQL 透传入口已删除。
 - Handler 已切换为语义化 repo 方法：
  - `ListUserIDsByUserGroup`
  - `ListTunnelIDsByTunnelGroup`
  - `ListGroupPermissionPairsByUserGroup`
  - `ListGroupPermissionPairsByTunnelGroup`
 ### 9.6 ✅ P3：Import 函数已全部 GORM 化
 `repository.go` 中 Import 相关函数已完成迁移：
 - `importUsers`
 - `importNodes`
 - `importTunnels`（含 `chain_tunnel` 子项 upsert）
 - `importForwards`（含 `forward_port` 覆盖写入）
 - `importUserTunnels`
 - `importSpeedLimits`
 - `importTunnelGroups`
 - `importUserGroups`
 - `importPermissions`
 - `importConfigs`（原本已是 GORM）
 迁移后统一采用 `Clauses(clause.OnConflict{Columns: id/name, DoUpdates: ...}).Create(&model)` 模式，
 保留原 `ON CONFLICT ... DO UPDATE` 语义；Import 区段 `tx.Exec`/`tx.Raw` 已清零。
 ### 9.7 ✅ P4：`h.repo.DB() == nil` 检查已清理
 `internal/http/handler/` 下已无 `h.repo.DB()` 直接访问；handler 仅通过语义化 repo 方法进行数据访问。
 ### 9.8 ✅ P5：Repository 层 Raw 已收敛（仅保留 PG 序列修复 DDL）
 当前生产代码中 `.Raw()` 已清零；仅剩 `repository.go` 的 4 处 `Exec()`，全部位于 PG 序列修复 DDL：
 - `CREATE SEQUENCE IF NOT EXISTS ...`
 - `ALTER TABLE ... ALTER COLUMN id SET DEFAULT nextval(...)`
 - `ALTER SEQUENCE ... OWNED BY ...`
 - `SELECT setval(...::regclass, ?, ?)`
 以上 4 处属于数据库管理 DDL/序列同步语义，当前保留，不再继续向 GORM 链式调用替换。
 `repository_federation.go` / `repository_control.go` / `repository_flow.go` 已完成 GORM 化（Raw=0）。

 # BACKEND HTTP HANDLER KNOWLEDGE BASE
 **Generated:** Thu Feb 26 2026
 ## OVERVIEW
 HTTP request handlers for FLVX Admin API. Core business logic layer.
 **Stack:** Go 1.24, net/http, GORM via Repository pattern.
 ## STRUCTURE
 ```
 handler/
 ├── handler.go        # Main Handler struct, login/captcha, job scheduling
 ├── control_plane.go  # Node control plane API (add/delete/list)
 ├── federation.go     # Federation/cluster sync API
 ├── flow_policy.go    # Traffic policy API
 ├── jobs.go           # Background job management (sync, cleanup)
 ├── mutations.go      # CRUD for users, tunnels, forwards (~3700 LOC)
 └── upgrade.go        # System upgrade API
 ```
 ## WHERE TO LOOK
 | Task | Location | Notes |
 |------|----------|-------|
 | **User/Tunnel CRUD** | `mutations.go` | Largest file; all create/update/delete ops |
 | **Login/Captcha** | `handler.go` | Login flow, captcha verification |
 | **Federation Sync** | `federation.go` | Panel-to-panel sync |
 | **Traffic Policies** | `flow_policy.go` | Flow limiting, quota management |
 | **Background Jobs** | `jobs.go` | Scheduled sync/cleanup tasks |
 | **Node Control** | `control_plane.go` | Node add/delete/list operations |
 ## CONVENTIONS
 - Inherits from parent: GORM via Repository pattern, JWT in Authorization header.
 - Large files expected (`mutations.go` ~3700 LOC - central mutation hub).
 - Uses `repo.Repository` for DB access via `h.repo.XXX()` methods.
 - Handlers never call `repo.DB()` directly — all queries go through Repository methods.
 - Domain-driven file split: one file per functional area (federation, jobs, etc.).
 ## ANTI-PATTERNS
 - Do NOT let handlers call `repo.DB()` directly — add a Repository method instead.
 - Do NOT change handler signatures without updating router.go.
 ## COMMANDS
 ```bash
 cd go-backend
 go test ./internal/http/handler/...
 ```
