feat: restrict user permissions and multi-node IP constraints

- Non-admin users cannot set speedId or inPort on forward create/update - Multi-entrance tunnels disable custom listen IP for forwards - Multi-exit tunnels disable custom connect IP - Multi-node hop chains disable custom connect IP per hop - Remove tunnel-first-IP fallback in forward ingress resolution - Add contract tests for non-admin permission restrictions Entire-Checkpoint: 133693290660

-name: security-scan
-description: Scan your Claude Code configuration (.claude/ directory) for security vulnerabilities, misconfigurations, and injection risks using AgentShield. Checks CLAUDE.md, settings.json, MCP servers, hooks, and agent definitions.
-origin: ECC
---
-
-# Security Scan Skill
-
-Audit your Claude Code configuration for security issues using [AgentShield](https://github.com/affaan-m/agentshield).
-
-## When to Activate
-
- Setting up a new Claude Code project
- After modifying `.claude/settings.json`, `CLAUDE.md`, or MCP configs
- Before committing configuration changes
- When onboarding to a new repository with existing Claude Code configs
- Periodic security hygiene checks
-
-## What It Scans
-
-| File | Checks |
-|------|--------|
-| `CLAUDE.md` | Hardcoded secrets, auto-run instructions, prompt injection patterns |
-| `settings.json` | Overly permissive allow lists, missing deny lists, dangerous bypass flags |
-| `mcp.json` | Risky MCP servers, hardcoded env secrets, npx supply chain risks |
-| `hooks/` | Command injection via interpolation, data exfiltration, silent error suppression |
-| `agents/*.md` | Unrestricted tool access, prompt injection surface, missing model specs |
-
-## Prerequisites
-
-AgentShield must be installed. Check and install if needed:
-
-```bash
-# Check if installed
-npx ecc-agentshield --version
-
-# Install globally (recommended)
-npm install -g ecc-agentshield
-
-# Or run directly via npx (no install needed)
-npx ecc-agentshield scan .
-```
-
-## Usage
-
-### Basic Scan
-
-Run against the current project's `.claude/` directory:
-
-```bash
-# Scan current project
-npx ecc-agentshield scan
-
-# Scan a specific path
-npx ecc-agentshield scan --path /path/to/.claude
-
-# Scan with minimum severity filter
-npx ecc-agentshield scan --min-severity medium
-```
-
-### Output Formats
-
-```bash
-# Terminal output (default) — colored report with grade
-npx ecc-agentshield scan
-
-# JSON — for CI/CD integration
-npx ecc-agentshield scan --format json
-
-# Markdown — for documentation
-npx ecc-agentshield scan --format markdown
-
-# HTML — self-contained dark-theme report
-npx ecc-agentshield scan --format html > security-report.html
-```
-
-### Auto-Fix
-
-Apply safe fixes automatically (only fixes marked as auto-fixable):
-
-```bash
-npx ecc-agentshield scan --fix
-```
-
-This will:
- Replace hardcoded secrets with environment variable references
- Tighten wildcard permissions to scoped alternatives
- Never modify manual-only suggestions
-
-### Opus 4.6 Deep Analysis
-
-Run the adversarial three-agent pipeline for deeper analysis:
-
-```bash
-# Requires ANTHROPIC_API_KEY
-export ANTHROPIC_API_KEY=your-key
-npx ecc-agentshield scan --opus --stream
-```
-
-This runs:
-1. **Attacker (Red Team)** — finds attack vectors
-2. **Defender (Blue Team)** — recommends hardening
-3. **Auditor (Final Verdict)** — synthesizes both perspectives
-
-### Initialize Secure Config
-
-Scaffold a new secure `.claude/` configuration from scratch:
-
-```bash
-npx ecc-agentshield init
-```
-
-Creates:
- `settings.json` with scoped permissions and deny list
- `CLAUDE.md` with security best practices
- `mcp.json` placeholder
-
-### GitHub Action
-
-Add to your CI pipeline:
-
-```yaml
- uses: affaan-m/agentshield@v1
-  with:
-    path: '.'
-    min-severity: 'medium'
-    fail-on-findings: true
-```
-
-## Severity Levels
-
-| Grade | Score | Meaning |
-|-------|-------|---------|
-| A | 90-100 | Secure configuration |
-| B | 75-89 | Minor issues |
-| C | 60-74 | Needs attention |
-| D | 40-59 | Significant risks |
-| F | 0-39 | Critical vulnerabilities |
-
-## Interpreting Results
-
-### Critical Findings (fix immediately)
- Hardcoded API keys or tokens in config files
- `Bash(*)` in the allow list (unrestricted shell access)
- Command injection in hooks via `${file}` interpolation
- Shell-running MCP servers
-
-### High Findings (fix before production)
- Auto-run instructions in CLAUDE.md (prompt injection vector)
- Missing deny lists in permissions
- Agents with unnecessary Bash access
-
-### Medium Findings (recommended)
- Silent error suppression in hooks (`2>/dev/null`, `|| true`)
- Missing PreToolUse security hooks
- `npx -y` auto-install in MCP server configs
-
-### Info Findings (awareness)
- Missing descriptions on MCP servers
- Prohibitive instructions correctly flagged as good practice

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

+
+### 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

+```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)
+

+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

+3. 创建转发:
+   隧道入口节点IDs → forward_port(forward_id, node_id, port)

+
+### 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

+
+#### 后端 (约200行)
+
+| 文件 | 改动 |
+|------|------|
+| `model/model.go` | Node/ForwardPort/ChainTunnel 增加3个字段 |
+| `repository_mutations.go` | CreateNode/UpdateNode 处理 extraIPs 参数 |
+| `repository_control.go` | GetNodeRecord/ListNodeAllIPs 辅助函数 |
+| `repository.go` | resolveForwardIngress 使用 forward_port.in_ip |
+| `handler/mutations.go` | selectTunnelDialHost 优先使用 connectIP |
+
+#### 前端 (约150行)
+
+| 页面 | 改动 |
+|------|------|
+| 节点编辑 | 高级配置增加"额外IP" Input（逗号分隔） |
+| 转发编辑 | 入口端口旁增加"监听IP" Select（从入口节点IP选择） |
+| 隧道配置 | 出口节点行增加"连接IP" Select（从出口节点IP选择） |
+

+
+### UI 示意
+
+**节点编辑 - 高级配置**
+```

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

-# 功能请求：在规则页面显示隧道倍率
-
-## 问题描述
-
-当前规则（Forward）页面在列表中显示隧道名称，但**不显示隧道的流量倍率（trafficRatio）**。管理员在管理规则时无法快速查看该规则所使用的隧道倍率信息，需要跳转到隧道页面才能查看。
-
-## 期望行为
-
-在规则列表页面中，在隧道名称旁边或单独列显示该隧道的流量倍率（例如：`1x`, `0.5x`, `2x`）。
-
-## 建议实现位置
-
-### 前端修改
-
-1. **`vite-frontend/src/pages/forward.tsx`**
-   - 在 `Forward` interface 中添加 `tunnelTrafficRatio?: number` 字段
-   - 在表格列中添加倍率显示（可以在隧道名称 Chip 旁边或单独一列）
-   - 从 `userTunnel` 或 `getTunnelList` API 获取隧道倍率信息
-
-2. **显示格式建议**
-   ```tsx
-   <Chip className="...">
-     {forward.tunnelName} ({forward.tunnelTrafficRatio}x)
-   </Chip>
-   ```
-   或者单独一列：
-   ```tsx
-   <TableCell>
-     {forward.tunnelTrafficRatio}x
-   </TableCell>
-   ```
-
-### 后端修改
-
-1. **`go-backend/internal/http/handler/handler.go`**
-   - 在 `forwardList` 接口返回中添加隧道的 `trafficRatio` 字段
-   - 需要在查询 Forward 时 JOIN Tunnel 表获取倍率信息
-
-2. **或者在前端加载规则后，批量获取隧道信息**
-   - 调用 `getTunnelList` 获取所有隧道信息
-   - 根据 `tunnelId` 匹配倍率
-
-## 相关文件
-
- 前端：`vite-frontend/src/pages/forward.tsx`
- 前端类型：`vite-frontend/src/api/types.ts`
- 后端：`go-backend/internal/http/handler/handler.go`
- 隧道类型定义：`vite-frontend/src/api/types.ts` (TunnelApiItem)
-
-## 优先级
-
-中等 - 不影响核心功能，但能提升管理效率
-
-## 截图参考
-
-隧道页面已显示倍率：
- 位置：隧道卡片统计信息区域
- 显示格式：`流量倍率 {trafficRatio}x`

 ## CONVENTIONS
- **Skills & MCP**: Always prefer using available skills (via `skill` tool) and MCP tools when applicable. Check for relevant skills before implementing from scratch.
 - **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.

-# 011 转发服务名升级兼容与节点滚动升级
-
-## 目标
- 修复旧版本升级后编辑转发/隧道出现 `service not found`（service不存在）的问题。
- 在后端加入兼容自愈逻辑，允许旧命名与新命名共存过渡。
- 给出低风险节点升级顺序，避免一次性全量切换带来的中断。
-
-## Checklist
- [x] 定位回归路径：服务名从 `forward_user_0` 迁移到真实 `user_tunnel_id` 后，与旧运行态不一致导致控制失败。
- [x] 在 `UpdateService` 的兼容路径加入旧服务清理后重建逻辑。
- [x] 在 `Pause/Resume` 控制路径加入首次 not found 后自愈重试逻辑。
- [x] 增加回归测试覆盖兼容行为。
- [x] 执行 `go-backend` 相关测试并记录结果。
- [x] 输出运维侧“后端先行 + agent 灰度升级 + 批量重部署”操作步骤。
-
-## 变更说明（实施中）
- 后端控制面将在检测到升级期的服务名不一致时进行自动自愈，降低人工干预和手工重建成本。
-
-## 测试记录
- 命令：`cd go-backend && go test ./internal/http/handler/...`
- 结果：通过。
-
-## 运维升级顺序（推荐）
-1. 先发布本次后端兼容补丁（无需等待所有 agent 同步升级）。
-2. 按 10%-20% 灰度分批升级 agent（低风险节点 -> 非高峰节点 -> 全量）。
-3. 每批升级后执行一次“转发批量重部署”，将运行态统一到新服务命名。
-4. 观察日志中 `service .* not found` 是否清零，再推进下一批。
-5. 全量稳定后保留兼容逻辑至少一个小版本周期，再评估收敛。

-# Plan 012: 允许用户自定义转发入口端口（限制在节点端口范围内）
-
-**Issue**: #268  
-**状态**: 已完成
-
-## 背景
-
-当前版本限制了普通用户自定义转发入口端口 (inPort) 的能力，导致：
- 用户迁移数据后无法保留原有端口配置
- 无法编辑转发配置
- 需要重建所有转发，操作繁琐
-
-## 实现方案
-
-允许用户和管理员自定义转发入口端口，但强制在节点端口设置的范围内。
-
-### 默认行为
- 不填写端口 → 随机分配（在端口范围内）
- 填写端口 → 使用指定端口（需在范围内且不冲突）
-

-## Investigation Note
-
- Forward update still has its own independent `address already in use` recovery path in `syncForwardServicesWithWarnings` / `rebindForwardServiceOnSelfOccupiedPort`; tunnel update linkage is not the only possible source of the symptom.
- Tunnel update also triggers downstream forward `UpdateService` for bound forwards, so users can still observe the same error around a tunnel edit even when the failing runtime is on the tunnel side.
- Real node output can collapse spaces into variants like `address alreadyin use` / `cannotassignrequestedaddress`; bind-conflict detection now normalizes whitespace before classifying the error.
- Forward self-heal cleanup now deletes every candidate runtime name variant instead of stopping after the first successful delete, which avoids leaving sibling `_tcp`/`_udp` services behind to keep the port occupied.

-# 020 AJAX No-refresh UX
-
-## Objective
-
- Implement issue `#276` as a focused frontend UX improvement initiative, not a full data-layer rewrite.
- Keep the existing `axios + local React state + custom hooks` architecture, and extend it with polling, realtime hardening, and local state patching where it improves responsiveness.
- Deliver the work in phases so the highest-value improvements ship first: dashboard auto-refresh and node realtime resilience, then local list updates after mutations, then batch progress and search/filter polish.
-
-## Non-goals
-
- Do not introduce `@tanstack/react-query`, SWR, or other new frontend data libraries for this issue.
- Do not rewrite page architecture, routing, or modal flows that already submit asynchronously without browser reloads.
- Do not require backend changes unless a batch-progress requirement cannot be met with the current API surface.
- Do not change the raw JWT auth convention used by `vite-frontend/src/api/network.ts`.
-
-## Current State
-
- `vite-frontend/src/pages/node/use-node-realtime.ts` and `vite-frontend/src/pages/node.tsx` already provide websocket-driven node status, system info, and upgrade progress updates.
- `vite-frontend/src/pages/forward.tsx`, `vite-frontend/src/pages/tunnel.tsx`, `vite-frontend/src/pages/user.tsx`, and `vite-frontend/src/pages/node.tsx` already submit forms asynchronously, so the main remaining gap is consistency of post-submit local refresh behavior.
- `vite-frontend/src/pages/dashboard/use-dashboard-data.ts` currently fetches dashboard data only once on mount, so traffic charts and counters do not auto-refresh.
- Several mutation handlers still rely on page-level reload functions such as `loadData()`, `loadUsers()`, or `loadNodes()` instead of patching only the changed records.
- Batch progress UI exists for node upgrade but not for other batch actions such as forward and tunnel operations.
-
-## Design Principles
-
- Prefer local state patching after successful mutations when the changed record set is known.
- Prefer targeted refetches over full-page refetches when the server is the source of truth for a small dependent dataset.
- Use polling only where realtime transport does not already exist.
- Pause or reduce background refresh work when the page is hidden to avoid unnecessary traffic.
- Keep UI feedback explicit: loading states, toast feedback, and visible progress for long-running batch actions.
-
-## Checklist
-
- [x] Refactor dashboard data loading into reusable refresh callbacks in `vite-frontend/src/pages/dashboard/use-dashboard-data.ts`.
- [x] Add dashboard traffic polling with visibility-aware pause/resume and safe notification deduplication.
- [x] Harden node realtime reconnection behavior in `vite-frontend/src/pages/node/use-node-realtime.ts` and define a fallback refresh path if websocket recovery fails.
- [x] Add shared local-list patch helpers for replace/remove/upsert patterns used by page-level mutation handlers.
- [x] Convert forward create/edit/delete/service-toggle flows in `vite-frontend/src/pages/forward.tsx` from whole-page refetches to local or targeted updates where safe.
- [x] Convert tunnel create/edit/delete flows in `vite-frontend/src/pages/tunnel.tsx` from whole-page refetches to local or targeted updates where safe.
- [x] Convert user create/edit/delete and user-tunnel permission mutation flows in `vite-frontend/src/pages/user.tsx` to local or targeted updates where safe.
- [x] Extend batch action UX to show visible progress or staged feedback for forward and tunnel batch operations.
- [x] Normalize search/filter behavior and document where client-side instant filtering is appropriate versus where server-side pagination must remain authoritative.
- [ ] Run focused frontend verification and record the result in this plan after implementation.
-
-## Implementation Plan
-
-### Phase 1 - Dashboard auto-refresh and node realtime resilience
-
-#### 1. Dashboard traffic/statistics auto-refresh
-
- Extract `loadPackageData()` and `loadAnnouncement()` in `vite-frontend/src/pages/dashboard/use-dashboard-data.ts` into stable callbacks so the hook can refresh data without re-running the whole mount sequence.
- Add a 5-second polling loop for package, flow, and chart data returned by `getUserPackageInfo()`.
- Keep announcement loading low-frequency or first-load only unless the API contract clearly expects live updates.
- Pause polling when `document.visibilityState !== "visible"`, then trigger an immediate refresh when the tab becomes visible again.
- Preserve current loading UX for first load, but use a silent refresh path for polling so the page does not flicker.
-
-#### 2. Dashboard notification safety
-
- Audit `checkExpirationNotifications()` in `vite-frontend/src/pages/dashboard/use-dashboard-data.ts` so polling does not repeatedly emit expiration warnings.
- Continue using notification deduplication, but base it on stable expiration identifiers rather than every poll cycle.
- Ensure refreshes that only change traffic counters do not retrigger expiry toasts.
-
-#### 3. Node realtime hardening
-
- Review `vite-frontend/src/pages/node/use-node-realtime.ts` reconnect logic, which currently stops after a fixed retry budget.
- Replace the hard stop with controlled backoff reconnect behavior, or explicitly trigger a degraded polling fallback once retry exhaustion is reached.
- If a fallback list refresh is introduced, merge incoming node metadata with existing `systemInfo`, `connectionStatus`, and upgrade-progress state so live metrics are not wiped during recovery.
- Keep the existing offline debounce behavior in `vite-frontend/src/pages/node/use-node-offline-timers.ts`.
-
-### Phase 2 - Local mutation updates and partial refreshes
-
-#### 4. Shared list-patching helpers
-
- Add small reusable helpers for common state operations such as:
-  - replace one item by `id`
-  - remove one or many items by `id`
-  - upsert a created or updated item into an ordered list
-  - preserve derived UI-only fields during server payload merges
- Keep these helpers local to the frontend codebase and avoid introducing a generic state-management abstraction.
-
-#### 5. Forward page partial refresh conversion
-
- Target `vite-frontend/src/pages/forward.tsx` mutation handlers first because the page already contains some optimistic/local patterns.
- Preserve the current local behavior for service toggles, but review rollback handling so final UI state matches backend truth after success or failure.
- Change create/edit/delete flows to patch `forwards` state directly when the response payload is sufficient.
- Use targeted refetches only when an operation changes dependent datasets that are not reliably derivable from the local page state.
- Re-check grouped ordering, collapsed-state persistence, and selected-row state after local mutations.
-
-#### 6. Tunnel page partial refresh conversion
-
- Update `vite-frontend/src/pages/tunnel.tsx` so create/edit/delete mutate `tunnels` state directly instead of always calling `loadData()`.
- Keep node reference data refresh separate from tunnel list refresh so a tunnel mutation does not force a full page data reload.
- Preserve existing drag-sort behavior and ensure local patching keeps `inx` and stored order consistent.
-
-#### 7. User page partial refresh conversion
-
- Update `vite-frontend/src/pages/user.tsx` so create/edit/delete patch the `users` list when the current page can be updated safely.
- Update user-tunnel permission flows to patch `userTunnels` directly after assign, edit, remove, and flow-reset operations.
- Respect server-side pagination semantics for the user list; if the server response does not provide enough data for a safe local patch, use a targeted page refetch rather than a full multi-dataset refresh.
- Keep current modal and toast behavior unchanged unless the local update path exposes stale-state issues.
-
-### Phase 3 - Batch progress UX and search/filter polish
-
-#### 8. Batch progress UX
-
- Use the node upgrade progress model in `vite-frontend/src/pages/node.tsx` as the UI reference for long-running operations.
- Review `vite-frontend/src/pages/forward/batch-actions.ts` and tunnel batch handlers to determine whether current APIs expose enough intermediate state for real progress.
- If only final summary APIs are available, implement staged client-side progress feedback such as `processing X/Y`, current action label, success count, and failure count.
- If the UX requirement cannot be met without backend support, document the missing backend contract and split the work into frontend and backend follow-ups.
-
-#### 9. Search and filter responsiveness
-
- Preserve instant client-side filtering on pages that already hold the authoritative dataset locally, including node, tunnel, and forward pages.
- Audit the user page separately because it depends on server-side pagination and keyword search.
- If user-page instant filtering is desired, choose one of two explicit strategies:
-  - keep server-side pagination authoritative and add debounce for keyword-triggered requests, or
-  - load a larger local dataset only if product requirements accept the cost.
- Do not silently mix partial client filtering with incomplete paginated datasets.
-
-## Risks and Mitigations
-
- Repeated dashboard polling may spam expiry toasts.
-  - Mitigation: deduplicate notifications based on expiration identity and only emit on meaningful state changes.
- Node recovery refreshes may wipe websocket-derived metrics.
-  - Mitigation: merge fetched node metadata into existing live state instead of replacing the whole record blindly.
- Local mutation patching may desynchronize grouped, sorted, or selected views.
-  - Mitigation: patch canonical source arrays first, then recompute derived memoized groupings from state.
- Batch APIs may not expose progress details.
-  - Mitigation: implement client-side staged progress where possible and document backend gaps where not.
- User-page local updates may conflict with pagination semantics.
-  - Mitigation: prefer targeted page refetch over unsafe optimistic filtering or cross-page list mutation.
-
-## Verification Plan
-
- Dashboard:
-  - Open `dashboard` and confirm traffic counters and chart data refresh at least once every 5 seconds without manual reload.
-  - Confirm hidden-tab pause and visible-tab immediate refresh behavior.
-  - Confirm expiry toasts do not repeat on every polling cycle.
- Nodes:
-  - Confirm websocket-driven online/offline transitions still work.
-  - Simulate websocket interruption and verify reconnect or fallback refresh behavior.
-  - Confirm recovery does not clear existing live metrics unexpectedly.
- Forwards, tunnels, users:
-  - Create, edit, delete, enable, disable, and reset flows without browser reload.
-  - Confirm the affected rows update immediately and other unrelated rows stay stable.
-  - Confirm selection state, ordering, and modal close behavior remain correct after local patching.
- Batch actions:
-  - Confirm visible progress or staged status feedback exists during long-running operations.
-  - Confirm success and failure summaries remain accurate after completion.
- Build:
-  - Run `cd vite-frontend && npm run build`.

- Ship Phase 1 first because it matches the issue approval priority and provides the clearest user-visible gain.
- Keep each phase in reviewable commits so regressions in local list patching can be isolated quickly.
- If backend support becomes necessary for real batch progress, land the frontend scaffolding separately and track the backend dependency explicitly.
-
-## Test Record
-
- Command: `cd vite-frontend && npm install`
- Result: passed.
- Command: `cd vite-frontend && npm run build`
- Result: passed.
