fix: preserve speed_limit and auto_clear when saving forwards and user tunnels (#259)

## Summary
- Add `speed_limit` and `auto_clear` fields to forward update mutation
to prevent data loss on save
- Update user tunnel save mutation to preserve these fields when editing
tunnels
- Add contract test to verify forward save preserves `speed_limit`
- Add plan documents (006, 007, 008) tracking the fix

## Changes
- `go-backend/internal/http/handler/mutations.go`: Add missing fields to
forward and user tunnel update logic
- `go-backend/tests/contract/forward_contract_test.go`: Add test case
for speed_limit preservation
- `vite-frontend/src/pages/forward.tsx`: Pass speed_limit and auto_clear
on save
- `vite-frontend/src/pages/user.tsx`: Pass speed_limit and auto_clear on
user tunnel save

+
+## 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。

+
+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。

+}
+```
+
+#### 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"`

+    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

+    }
+    // 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

+## Key File Paths and their purposes:
+
+### Frontend: Forward Edit/create dialog component
+- **Main file:** `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/mighty-nebula/vite-frontend/src/pages/forward.tsx`
+  - Displays the forwarding list and handles all create/edit/delete/forwards
+- Has `inIp` and `inPort` fields
+- Shows entry port and dialog/form with validation
+- Uses React-hook-form with state management
+- Calls `createForward`, `updateForward`, `deleteForward`, `pauseForwardService`, `resumeForwardService`, APIs
+
+- Imports API functions from `@/api`
+
+### Backend: Forwarding data model and API handlers
+- **Main model file:** `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/mighty-nebula/go-backend/internal/store/model/model.go`
+  - GORM model definition for `Forward` struct does basic forwarding configuration
+  - Related models: `ForwardPort`, `Tunnel`, `UserForwardDetail` (view struct)
+
+  - **API handlers:** `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/mighty-nebula/go-backend/internal/http/handler/mutations.go`
+  - Create/update/delete operations
+  - Entry port handling via `inPort` field
+
+- **Repository layer:** `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/mighty-nebula/go-backend/internal/store/repo/repository_mutations.go`
+  - CRUD operations for  - `resolveForwardIngress` function in `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/mighty-nebula/go-backend/internal/store/repo/repository.go`
+  - Computes `inIp` and `inPort` from joins
+
+### Current data model structure for forwards
+
+From `go-backend/internal/store/model/model.go`:
+
+```go

+```
+
+```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

+## 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.

+# 001 Fix 211 ConnectIP Full Chain
+
+## Checklist
+
+- [x] Analyze connectIp/inIp full chain across diagnosis/runtime/redeploy paths.
+- [x] Fix diagnosis target resolution to honor selected `connectIp` for chain hops.
+- [x] Fix tunnel state reconstruction to preserve `connectIp` on chain/out nodes.
+- [x] Add contract regression tests for normal + stream diagnosis target IP behavior.
+- [x] Add handler regression test for redeploy state reconstruction preserving `connectIp`.
+- [x] Run backend handler and contract test suites.
+
+## Notes
+
+- Diagnosis now uses `chain_tunnel.connect_ip` for both stream start preview and runtime probing.
+- Redeploy/batch-redeploy no longer drops `connectIp` during `reconstructTunnelState`.

+- [x] Confirm forward edit flow and identify why untouched listen IP gets overwritten.
+- [x] Update frontend forward edit submit logic to only send `inIp` when user explicitly changes listen IP.
+- [x] On tunnel switch in edit form, reset listen IP to default unless user reselects.
+- [x] Update backend forward update logic to preserve existing `forward_port.in_ip` when request omits `inIp` and tunnel is unchanged.
+- [x] Keep backend behavior explicit: if `inIp` is sent (including empty), apply requested value; if tunnel changed with no `inIp`, use default bind.
