feat: forward management enhancements and bind IP preservation (#256)

## Summary
- Fix bind IP preservation when editing forwards without explicit inIp
changes
- Add ny format import support with node-based tunnel matching and auto
port assignment
- Add custom IP selection for nodes, tunnels, and forwards
- Add tunnel group collapse and drag sorting in full mode
- Add global compact mode with alpha8 list layout
- Various bug fixes and improvements

## Test plan
- [x] Unit tests for forward port replacement with preserved InIP
- [x] Manual testing of forward edit flow
- [x] Verified bind IP is preserved when editing forwards without
touching the inIp field

+
+## 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。

+## 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。

+
+### 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,
+    "udpListenAddr": n.UDPListenAddr,
+    "version":       nullableString(n.Version),
+    "http":          n.HTTP, "tls": n.TLS, "socks": n.Socks,
+    "status": n.Status, "isRemote": n.IsRemote,
+    // ...
+})
+```
+
+#### API端点
+| 端点 | Handler | 功能 |
+|------|---------|------|
+| `POST /api/v1/node/list` | `h.nodeList` | 列出节点 |
+| `POST /api/v1/node/create` | `h.nodeCreate` | 创建节点 |
+| `POST /api/v1/node/update` | `h.nodeUpdate` | 更新节点 |
+| `POST /api/v1/node/delete` | `h.nodeDelete` | 删除节点 |
+
+---
+
+### 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

+
+### 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)

+        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

+    Inx       sql.NullInt64  // 跳转序号
+    Protocol  sql.NullString

+
+### 4. 修改连接地址需要改动的关键位置
+
+如果要修改下一跳连接地址的选择逻辑，需要关注以下位置：
+
+| 修改目标 | 文件 | 行号 | 函数 |
+|---------|------|------|------|
+| **IP地址选择策略** | `mutations.go` | L2654-2699 | `selectTunnelDialHost()` |

+| **IPv6地址提取** | `mutations.go` | L2765-2773 | `pickNodeAddressV6()` |
+| **端口获取** | `mutations.go` | L2585-2588 | `buildTunnelChainConfig()` |
+| **端口分配逻辑** | `repository_mutations.go` | ~L459 | `PickNodePortTx()` |
+| **端口写入数据库** | `repository_mutations.go` | L398-406 | `CreateChainTunnelTx()` |
+| **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

+## 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
+```

+2. Backend: The forwarding data model and API handlers (likely in go-backend/)
+3. How the current "入口端口" (entry port) is handled

+- Files related to "forward" or "转发" or "tunnel" or "隧道"
+- Data models for forwarding rules
+- API handlers for creating/editing forwards

+  - 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`

+
+### 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

+## 最终设计方案
+
+### 核心需求

+| 场景 | 配置位置 | 选择内容 |
+|------|----------|----------|
+| 转发 | 转发创建/编辑 | 入口监听IP（从入口节点IP列表选择） |
+| 隧道 | 隧道配置 | 出口节点连接IP（从出口节点IP列表选择） |

 ## 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.
+- **Auth**: `Authorization` header carries the raw JWT token (no `Bearer` prefix) between `vite-frontend/` and `go-backend/`.
+- **Module Fork**: `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.

+- **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/jdtls/typescript-language-server); rely on grep-based navigation.
+- LSP servers are not installed in this environment (gopls/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.

-   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
 
-   1. Definitions.
+                            Preamble
 
-      "License" shall mean the terms and conditions for use, reproduction,
-      and distribution as defined by Sections 1 through 9 of this document.
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
 
-      "Licensor" shall mean the copyright owner or entity authorized by
-      the copyright owner that is granting the License.
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
 
-      "Legal Entity" shall mean the union of the acting entity and all
-      other entities that control, are controlled by, or are under common
-      control with that entity. For the purposes of this definition,
-      "control" means (i) the power, direct or indirect, to cause the
-      direction or management of such entity, whether by contract or
-      otherwise, or (ii) ownership of fifty percent (50%) or more of the
-      outstanding shares, or (iii) beneficial ownership of such entity.
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
 
-      "You" (or "Your") shall mean an individual or Legal Entity
-      exercising permissions granted by this License.
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
 
-      "Source" form shall mean the preferred form for making modifications,
-      including but not limited to software source code, documentation
-      source, and configuration files.
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
 
-      "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.
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
 
-      "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).
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
 
-      "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.
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
 
-      "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."
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
 
-      "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.
+  The precise terms and conditions for copying, distribution and
+modification follow.
 
-   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.
+                       TERMS AND CONDITIONS
 
-   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.
+  0. Definitions.
 
-   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:
+  "This License" refers to version 3 of the GNU General Public License.
 
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
 
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
 
-      (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
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
 
-      (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.
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
 
-      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.
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
 
-   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.
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
 
-   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.
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
 
-   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.
+  1. Source Code.
 
-   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.
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
 
-   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.
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
 
-   END OF TERMS AND CONDITIONS
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
 
-   APPENDIX: How to apply the Apache License to your work.
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
 
-      To apply the Apache License to your work, attach the following
-      boilerplate notice, with the fields enclosed by brackets "[]"
-      replaced with your own identifying information. (Don't include
-      the brackets!)  The text should be enclosed in the appropriate
-      comment syntax for the file format. We also recommend that a
-      file or class name and description of purpose be included on the
-      same "printed page" as the copyright notice for easier
-      identification within third-party archives.
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
 
-   Copyright [yyyy] [name of copyright owner]
+  The Corresponding Source for a work in source code form is that
+same work.

+  2. Basic Permissions.
 
-       http://www.apache.org/licenses/LICENSE-2.0
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
 
-   Unless required by applicable law or agreed to in writing, software
-   distributed under the License is distributed on an "AS IS" BASIS,
-   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.
-   See the License for the specific language governing permissions and
-   limitations under the License.
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+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>.

+#### 快速部署（安装最新版）
 面板端：

 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
@@ -27,6 +30,91 @@ curl -L https://raw.githubusercontent.com/Sagit-chu/flux-panel/main/panel_instal
 curl -L https://raw.githubusercontent.com/Sagit-chu/flux-panel/main/install.sh -o install.sh && chmod +x install.sh && ./install.sh
 ```
 
+#### 安装特定版本
+从 [Releases](https://github.com/Sagit-chu/flux-panel/releases) 页面复制对应版本的安装命令，脚本会自动安装该版本而非最新版。
+
+面板端（以 2.1.0 为例）：
+```bash
+curl -L https://github.com/Sagit-chu/flux-panel/releases/download/2.1.0/panel_install.sh -o panel_install.sh && chmod +x panel_install.sh && ./panel_install.sh
+```
+节点端（以 2.1.0 为例）：
+```bash
+curl -L https://github.com/Sagit-chu/flux-panel/releases/download/2.1.0/install.sh -o install.sh && chmod +x install.sh && ./install.sh
+```
+
+#### PostgreSQL 部署（Docker Compose）
+
+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`。默认仍使用 SQLite，切换到 PostgreSQL 只需要配置环境变量。
+
+1) 在 `docker-compose` 同目录创建或修改 `.env`：
+
+```bash
+JWT_SECRET=replace_with_your_secret
+BACKEND_PORT=6365
+FRONTEND_PORT=6366
+
+DB_TYPE=postgres
+DATABASE_URL=postgres://flux_panel:replace_with_strong_password@postgres:5432/flux_panel?sslmode=disable
+
+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。

+
+## Modifications
+This fork (FLVX) is no longer a light patch on top of the upstream project. It has been deeply reworked, with both backend and frontend rebuilt around a Go-based architecture.
+
+### 1. Backend (Rewritten)
+- **Removed**: The original `springboot-backend/` (Java/Spring Boot) implementation.
+- **Added**: A fully rewritten `go-backend/` service (Go), including updated data and API handling for panel management.
+
+### 2. Frontend (Reworked)
+- **Reworked**: `vite-frontend/` has been substantially rebuilt to match the new backend contract and current UI layer architecture.
+- **Updated**: Dashboard pages/components and interaction flows for the current React/Vite stack.
+
+### 3. Forwarding Stack (Modified)
+- **Modified**: `go-gost/` forwarding agent wrapper.
+- **Modified**: `go-gost/x/` local fork of `github.com/go-gost/x`.
+
+### 4. Mobile Clients (Removed)
+- **Removed**: `android-app/` source code.
+- **Removed**: `ios-app/` source code.
+
+### 5. Deployment & Project Infrastructure
+- **Updated**: Docker deployment templates and installer output flow (IPv4/IPv6 compose variants).
+- **Updated**: Release installation scripts (`install.sh`, `panel_install.sh`) and supporting automation.
+- **Added/Updated**: Project-level engineering documentation (for example `AGENTS.md`).

 ### 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
-- **No ORM**: Uses raw SQL with `database/sql` and `modernc.org/sqlite`.
+- **GORM ORM**: Uses GORM with `glebarez/sqlite` (CGO-free) and `gorm.io/driver/postgres`.
+- **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
+
+| 步骤 | 任务 | 文件 | 状态 |
+|------|------|------|------|
+| 1.1 | `go get gorm.io/gorm gorm.io/driver/postgres github.com/glebarez/sqlite` | `go.mod` | ✅ |
+| 1.2 | 创建 `internal/store/model/model.go`，定义全部 21 个表 Model | 新文件 | ✅ |
+| 1.3 | 为 `user` 表添加 `TableName()` 处理 PG 保留字 | model.go | ✅ |
+| 1.4 | 为复合唯一索引的表添加 GORM 索引 tag | model.go | ✅ |
+| 1.5 | 将 Backup 相关 struct 也迁移到 model/ | model.go | ✅ |
+| 1.6 | 验证 `go build ./...` 编译通过 | - | ✅ |
+
+### 阶段 2：GORM DB 初始化 ✅ 已完成
+
+| 步骤 | 任务 | 文件 | 状态 |
+|------|------|------|------|
+| 2.1 | 修改 Repository struct，`*store.DB` → `*gorm.DB` | repository.go | ✅ |
+| 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 | ✅ |
+| 2.5 | 实现种子数据逻辑（FirstOrCreate 替代 data.sql） | repository.go | ✅ |
+| 2.6 | 保留并适配 `ensurePostgresIDDefaults()`（用 `db.Exec()`） | repository.go | ✅ |
+| 2.7 | 保留并适配 `migrateSchema()` 增量迁移 | 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) |
+| 3.12 | Export 全部方法 | ~10 | ✅ |
+| 3.13 | Import 全部方法 | ~10 | ✅ 已全部改为 GORM `Clauses(clause.OnConflict)`（见 §9.6） |
+| **3.14** | **repository_mutations.go 全部方法 (~40 个)** | **~40** | **✅ 已全量改为 GORM 链式调用（见 §9.3）** |
+| **3.15** | **repository_federation.go 查询方法** | **~8** | **✅ 已全部改为 GORM 链式调用** |
+| **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 |
+|------|----------|------|----------|

+| `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）。
+
+---

+   - `go build ./...` ✅（使用显式 `GOMODCACHE/GOPATH/GOCACHE/HOME` 环境）
+   - `go test ./internal/store/repo/...` ✅
+
+### 10.3 本轮执行记录（2026-02-17，P2 部分）
+
+1. 将 tunnel 更新/chain 重建路径 SQL 下沉到 `repository_mutations.go`：
+   - 新增 `UpdateTunnelTx`
+   - 新增 `DeleteChainTunnelsByTunnelTx`
+   - 新增 `CreateChainTunnelTx`
+2. 将 handler 内部 SQL helper 迁移到 repo：
+   - 新增 `IsRemoteNodeTx`
+   - 新增 `PickNodePortTx`
+   - `replaceTunnelChainsTx` 改为 handler 方法并改用 repo 调用，不再直接 SQL
+3. 复扫结果：`mutations.go` 直接 SQL 从 27 处降至 17 处。
+4. 验证结果：
+   - `go build ./...` ✅
+   - `go test ./internal/store/repo/...` ✅
+
+### 10.4 本轮执行记录（2026-02-17，P2 收尾）
+
+1. 新增并落地事务语义化 repo 方法：
+   - `ReplaceTunnelGroupMembersTx` / `ReplaceUserGroupMembersTx`
+   - `ListUserIDsByUserGroupTx`
+   - `GetGroupPermissionPairByIDTx` / `DeleteGroupPermissionByIDTx`
+   - `RevokeGroupGrantsForRemovedUsersTx` / `RevokeGroupPermissionPairTx`
+   - `ReplaceFederationTunnelBindingsTx`
+2. 删除 handler 内 SQL helper（`queryInt64ListTx` / `revokeGroupGrantsForRemovedUsersTx` / `revokeGroupPermissionPairTx` / `replaceFederationTunnelBindingsTx`）。
+3. 复扫确认：`mutations.go` 生产路径 `tx.Exec`/`tx.Raw` = 0。
+4. 验证结果：
+   - `go build ./...` ✅
+   - `go test ./internal/store/repo/...` ✅

+# 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/...
+```
