feat(quota): add tunnel traffic quota with daily/monthly limits (#291) (#308)

Implement per-tunnel traffic quota feature:
- Add TunnelQuota model with daily/monthly usage tracking
- Integrate quota enforcement into flow accumulation path
- Pause forwards and disable tunnel when quota exceeded
- Block new forward creation/resume when tunnel quota disabled
- Auto-reset daily/monthly windows at 00:05 via maintenance job
- Add manual reset API endpoint for admins
- Include quota config in tunnel backup/restore
- Add frontend UI for quota settings and usage display

+规则标签页下，精简模式，和非精简模式一样要显示规则数量
+
+## Summary
+
+I have successfully modified `vite-frontend/src/pages/forward.tsx` to include the rule count ("{sortedForwards.length} 条规则") when the forward page is in the `compactMode` (精简模式) and `viewMode === "grouped"`. This ensures consistency with the regular view modes where the total rule count is already displayed.
+

+我已经详细查阅了节点卡片 (`vite-frontend/src/pages/node.tsx`) 的代码结构。由于现在处于**计划模式 (Plan Mode)**，我目前只能读取和分析，不能直接修改代码。
+
+我已经为你准备了详细的修改方案，这套方案同时满足你提到的 3 个要求：
+
+### 修改计划：
+
+**1. 统一限制卡片高度**
+*   **目标代码位置**：修改包裹 `Card` 的外层 `SortableItem` 的 `className`，以及 `Card` 内部的结构。
+*   **具体修改**：
+    *   给 `SortableItem` 内部渲染的 `div` 增加 `flex flex-col h-full`，使其占满整个 Grid 格子的高度。
+    *   给 `Card` 增加 `h-full flex flex-col` 类名。
+    *   在 `<CardBody>` 内部，将顶部的基础信息区域（包含备注、续费等）和底部的控制区域（系统监控及按钮）分开。给包含底部按钮区域的 div 添加 `mt-auto`，这样它就会自动被推到卡片的最底部，使所有的操作按钮和监控进度条在同一行水平对齐，从而强制拉伸中间的空白区域以保证卡片等高。
+
+**2. 限制「备注」只显示 1 行**
+*   **目标代码位置**：备注内容显示的 div (`{node.remark.trim()}`)。
+*   **具体修改**：
+    *   将包含备注文本的 `div` 上的 `whitespace-pre-wrap break-words` 替换为 `line-clamp-1 break-all`。
+    *   在这个文本外层包一个 `title={node.remark.trim()}` 属性（原生 Tooltip），这样用户只要把鼠标悬停在被截断的备注上，就能看到完整的备注内容。
+
+**3. 下次续费只显示距离到期**
+*   **目标代码位置**：`{node.expiryTime && node.expiryTime > 0 && node.renewalCycle && ( ... )}` 渲染逻辑内。
+*   **具体修改**：
+    *   精简现有的 3 行布局（具体时间、剩余时间 Chip、续费周期）。
+    *   将其压缩为 1 行显示，只展示带颜色的 Chip（里面包含了“还有 x 天”的 `expiryMeta.label`）。
+    *   为了保留完整信息，我们给这个 Chip 加上 `title` 属性，比如鼠标移上去会显示完整的：`下次续费：2026-12-01 (年付)`。
+    *   这会把原先极度占用垂直空间的 3 行内容直接缩减到单行。
+
+---
+
+如果这个方案符合你的预期，你可以退出计划模式（或者直接回复同意执行），我会在下一次交互中立即为你实施这些代码修改！

+我看过 issue #280，也把前后端相关实现路径过了一遍。这个需求适合做成“后端补字段，前端直接消费”的小改动，不建议只在前端二次拼装。
+
+- 现在 `/forward/list` 的数据来自 `h.repo.ListForwards()`，对应查询在 `go-backend/internal/store/repo/repository.go:700`，当前只 `LEFT JOIN tunnel` 取了 `tunnel_name`，还没把 `tunnel.traffic_ratio` 带出来。
+- 前端规则页自己的 `Forward` 类型定义在 `vite-frontend/src/pages/forward.tsx:102`，`mapForwardApiItems` 在 `vite-frontend/src/pages/forward.tsx:507` 负责把接口结果映射成本地状态；这里目前也没有倍率字段。
+- 规则列表的主要展示点有 3 处：表格隧道列 `vite-frontend/src/pages/forward.tsx:3306`、卡片副标题 `vite-frontend/src/pages/forward.tsx:3469`、分组标题 `vite-frontend/src/pages/forward.tsx:2919`。如果只改一处，体验会不一致。
+- 隧道页已经有统一的倍率展示格式 `vite-frontend/src/pages/tunnel.tsx:1336`，直接沿用 `"{trafficRatio}x"` 最稳。
+
+建议实现方案
+
+- 后端优先：在 `go-backend/internal/store/repo/repository.go:705` 的 `fwdRow` 增加 `TrafficRatio float64`，并在 `Select(...)` 中补上 `COALESCE(tunnel.traffic_ratio, 1.0) AS traffic_ratio`。
+- 后端返回：在构造 `item` 的地方把 `trafficRatio` 以 `tunnelTrafficRatio` 键返回，保持前端语义清晰，避免和规则自身字段混淆。
+- 前端类型：给 `vite-frontend/src/api/types.ts:45` 的 `ForwardApiItem` 增加 `tunnelTrafficRatio?: number`；给 `vite-frontend/src/pages/forward.tsx:102` 的本地 `Forward` interface 同步增加该字段。
+- 前端映射：在 `vite-frontend/src/pages/forward.tsx:507` 的 `mapForwardApiItems` 里做默认值归一化，比如没有值时回退到 `1`，避免旧数据或异常响应导致显示空白。
+- 前端展示：优先把倍率放进“隧道名称展示块”里，而不是新增独立列。原因是当前表格列已经偏宽，issue 也接受“名称旁边显示”；卡片和分组视图也更容易保持一致。建议形式：
+  - 表格：`TunnelName` 主文案 + 小号次级 `1x`
+  - 卡片：副标题显示为 `隧道名 · 1x`
+  - 分组标题：`隧道名` 后加一个轻量 Chip / muted 文本 `1x`
+
+为什么不建议纯前端拼装
+
+- `forward.tsx` 虽然在 `loadData` 里已经请求了 `getTunnelList()` 和 `userTunnel()`，但 `refreshForwardList()` 是独立刷新的，规则状态刷新时不保证隧道缓存始终同步，容易出现倍率滞后。
+- 当前分组逻辑主要基于规则数据本身，若依赖前端再按 `tunnelId` 做二次映射，会把一个本来单接口即可闭环的信息拆成两份状态，后面维护更麻烦。
+- 后端本来已经 `JOIN tunnel` 取名字，只是顺手再取一个倍率字段，成本最低。
+
+推荐实施步骤
+
+- 后端：扩展 `/forward/list` 查询与返回结构，默认倍率回退 `1.0`。
+- 合约测试：在 `go-backend/tests/contract/forward_contract_test.go` 增加对 `/forward/list` 返回 `tunnelTrafficRatio` 的断言，至少覆盖一个非默认值例如 `2.5`。
+- 前端类型：同步更新 `ForwardApiItem` 和页面内 `Forward`。
+- 前端映射：在 `mapForwardApiItems` 里规范化 `tunnelTrafficRatio`。
+- 前端 UI：统一更新表格、卡片、分组标题 3 处展示，避免 direct/grouped 两种模式信息不一致。
+- 回归验证：确认管理员和普通用户视角下，`/forward/list` 权限过滤不受影响，因为过滤逻辑在 `go-backend/internal/http/handler/handler.go:395` 之后仅按 `userId` 过滤，不会受新增字段影响。
+
+风险和注意点
+
+- `ForwardApiItem` 现在是宽松结构，短期不会因新增字段报错，但如果只改页面本地类型不改 API 类型，后面别处复用时会产生类型漂移。
+- 分组标题 `ForwardTunnelGroup` 目前只有 `tunnelName`，如果要在分组头也显示倍率，最好给分组结构补一个 `tunnelTrafficRatio?: number`，并在构建分组时从首条规则或同组规则里带出。
+- 需要统一倍率格式，避免出现 `1`, `1.0`, `1.00` 混用。建议做一个小格式化函数：整数显示 `1x`，小数保留必要精度如 `0.5x`、`1.25x`。
+- 若某条规则关联的隧道已删除，后端 `COALESCE(..., 1.0)` 能保证页面仍可显示默认 `1x`，不会变成空。
+
+验收标准
+
+- `/api/v1/forward/list` 每条规则都带 `tunnelTrafficRatio`。
+- 规则页 direct 表格模式能看到倍率。
+- grouped 卡片模式和分组标题也能看到倍率，信息一致。
+- 隧道缺失或旧数据情况下仍稳定显示 `1x`。
+- 普通用户只能看到自己的规则，但倍率字段仍正常返回。
+
+如果你要我下一步继续，我建议按这个实现顺序做：
+1. 先补后端查询和 contract test
+2. 再补前端类型与统一展示
+3. 最后跑 `go test ./tests/contract/...` 和前端 build 做回归

+You are auditing the FLVX frontend for GitHub issue #276 (AJAX no-refresh UX improvements). Read-only only. Focus on existing implementation status for: 1) dashboard traffic auto-refresh, 2) node status real-time updates, 3) form submissions without full page reload, 4) local/partial list refresh after CRUD/toggle, 5) batch operation progress UI, 6) search/filter instant response. Inspect relevant files under vite-frontend/src/pages and src/api. Return a concise report with: a) what already exists, b) what is missing or partial, c) specific file paths and functions to touch for an implementation plan, d) notable risks or edge cases. Do not edit anything.

+Concise audit for issue #276, focused on `vite-frontend/src/pages` and `src/api`.
+
+a) What already exists
+
+1. Dashboard traffic auto-refresh
+- Dashboard data is loaded via async API calls in a hook, not by page reload:
+  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/dashboard/use-dashboard-data.ts`
+  - `useDashboardData()` calls `getUserPackageInfo()` and `getAnnouncement()`.
+- The 24h traffic chart is already rendered from `statisticsFlows`:
+  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/dashboard.tsx`
+  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/dashboard/components/flow-chart-card.tsx`
+
+2. Node status real-time updates
+- This is the strongest existing area.
+- WebSocket realtime hook already exists:
+  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node/use-node-realtime.ts`
+  - `useNodeRealtime()`
+- Offline debounce exists:
+  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node/use-node-offline-timers.ts`
+- Node page consumes websocket messages and updates local state without reload:
+  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node.tsx`
+  - `handleWebSocketMessage()`
+  - `loadNodes()`
+- Realtime also includes system info updates and upgrade progress updates.
+
+3. Form submissions without full page reload
+- Broadly already implemented across main CRUD pages using async handlers + modal close + state refresh.
+- Examples:
+  - Nodes: `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node.tsx`
+    - `handleSubmit()`
+  - Tunnels: `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/tunnel.tsx`
+    - `handleSubmit()`
+  - Forwards: `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/forward.tsx`
+    - `handleSubmit()`
+  - Users: `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/user.tsx`
+    - `handleSubmitUser()`
+- I did not find page reload patterns in these CRUD pages (`location.reload` / `window.location.reload` absent there).
+
+4. Local/partial list refresh after CRUD/toggle
+- Some local optimistic/partial updates already exist:
+  - Node delete updates local state directly:
+    - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node.tsx`
+    - `confirmDelete()`
+  - Node edit updates local item directly:
+    - `handleSubmit()` edit branch
+  - Forward service toggle uses optimistic local update + rollback on failure:
+    - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/forward.tsx`
+    - `handleServiceToggle()`
+  - Sorting persists locally and updates item `inx` in-memory after success:
+    - Node `handleDragEnd()`
+    - Tunnel `handleDragEnd()`
+    - Forward `handleDragEnd()`
+
+5. Batch operation progress UI
+- Node upgrade has actual per-node progress UI:
+  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node.tsx`
+  - `upgradeProgress` state
+  - websocket `type === "upgrade_progress"` handling in `handleWebSocketMessage()`
+  - `<Progress />` render around lines ~1307+
+- Forward batch actions are factored and return structured outcomes:
+  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/forward/batch-actions.ts`
+
+6. Search/filter instant response
+- Instant client-side filtering already exists in:
+  - Nodes: `sortedNodes` memo filters by `searchKeyword`
+    - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node.tsx`
+  - Tunnels: `sortedTunnels`
+    - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/tunnel.tsx`
+  - Forwards: `orderedForwards`
+    - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/forward.tsx`
+- Forward also has instant client-side filter dropdowns (`filterUserId`, `filterTunnelId`).
+
+b) What is missing or partial
+
+1. Dashboard traffic auto-refresh: missing
+- `useDashboardData()` only fetches once on mount.
+- No polling, websocket, refetch trigger, focus refresh, or manual refresh hook.
+- So “AJAX no-refresh” exists only for initial load, not ongoing refresh.
+
+2. Node realtime: partial but good
+- Realtime status/system-info exists only for nodes.
+- It reconnects with limited retries (5 attempts) and then stops.
+- `loadNodes()` initially sets `systemInfo: null`, so a full reload can temporarily wipe metrics until WS catches up again.
+- No obvious fallback polling if websocket dies permanently.
+
+3. Form submission no full reload: mostly done
+- CRUD forms are already async and modal-driven.
+- But post-submit refresh style is inconsistent:
+  - some do local patch,
+  - many do full page-level list refetch (`loadData()`, `loadUsers()`, `loadNodes()`).
+
+4. Local/partial list refresh after CRUD/toggle: partial/inconsistent
+- Forward toggle is good and local.
+- Node edit/delete are relatively local.
+- But many operations still refetch the whole page dataset:
+  - Tunnel create/update/delete -> `loadData()`
+  - Forward create/update/delete -> `loadData()`
+  - User create/update/delete -> `loadUsers()`
+  - User tunnel assignment/update/remove -> `loadUserTunnels()`
+- This is AJAX and avoids full browser reload, but not “partial/local refresh” in the stronger UX sense.
+
+5. Batch operation progress UI: largely missing outside node upgrade
+- Tunnel batch delete/redeploy: only loading spinner/toast + full reload, no per-item progress/result panel.
+- Forward batch actions: summarized via toast and optional refresh, but no visible progress timeline/progress list.
+- User batch tunnel assignment: no progress UI beyond loading state.
+
+6. Search/filter instant response: mixed
+- Nodes/tunnels/forwards are instant client-side.
+- Users are not fully instant:
+  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/user.tsx`
+  - `loadUsers()` is server-driven and tied to `useEffect([pagination.current, pagination.size, searchKeyword])`
+  - Enter key also manually calls `handleSearch()`
+- So user search is AJAX but not purely local/instant in the same way.
+
+c) Specific file paths and functions to touch for an implementation plan
+
+Primary targets
+
+1. Dashboard auto-refresh
+- `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/dashboard/use-dashboard-data.ts`
+  - `useDashboardData()`
+  - extract `loadPackageData()` / `loadAnnouncement()` into stable callbacks
+  - add polling or visibility/focus-based refetch
+- `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/dashboard.tsx`
+  - if adding manual refresh indicator/button, this is the page entry
+- API source already exists:
+  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/api/index.ts`
+  - `getUserPackageInfo()`, `getAnnouncement()`
+
+2. Node realtime hardening / fallback
+- `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node/use-node-realtime.ts`
+  - `useNodeRealtime()`
+  - retry policy, reconnect strategy, possible fallback refresh trigger
+- `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node.tsx`
+  - `handleWebSocketMessage()`
+  - `loadNodes()`
+  - `handleSubmit()`
+  - `confirmDelete()`
+  - `handleBatchDelete()`
+
+3. Replace whole-list reloads with local/partial updates
+- Tunnels:
+  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/tunnel.tsx`
+  - `loadData()`
+  - `handleSubmit()`
+  - `confirmDelete()`
+  - `handleBatchDelete()`
+  - `handleBatchRedeploy()`
+- Forwards:
+  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/forward.tsx`
+  - `loadData()`
+  - `handleSubmit()`
+  - `confirmDelete()`
+  - `handleServiceToggle()`
+  - `handleBatchDelete()`
+  - `handleBatchToggleService()`
+  - `handleBatchRedeploy()`
+  - `handleBatchChangeTunnel()`
+- Users:
+  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/user.tsx`
+  - `loadUsers()`
+  - `handleSubmitUser()`
+  - `handleConfirmDelete()`
+  - `loadUserTunnels()`
+  - `handleBatchAssignTunnel()`
+  - `handleUpdateTunnel()`
+  - `handleConfirmRemoveTunnel()`
+  - `handleConfirmResetFlow()`
+  - `handleConfirmResetTunnelFlow()`
+
+4. Batch progress/result UX
+- Nodes already have a model to copy:
+  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node.tsx`
+  - `upgradeProgress`
+  - websocket `upgrade_progress`
+- Forward batch abstraction:
+  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/forward/batch-actions.ts`
+  - likely extend return shape if backend can expose richer progress/events
+- API endpoints involved:
+  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/api/index.ts`
+  - `batchDeleteForwards()`
+  - `batchPauseForwards()`
+  - `batchResumeForwards()`
+  - `batchRedeployForwards()`
+  - `batchChangeTunnel()`
+  - `batchDeleteTunnels()`
+  - `batchRedeployTunnels()`
+  - `batchDeleteNodes()`
+  - `batchUpgradeNodes()`
+
+5. Search/filter behavior normalization
+- `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/user.tsx`
+  - `loadUsers()`
+  - `handleSearch()`
+  - search input around lines ~718+
+- Nodes/tunnels/forwards already have memo-based client filtering and are the pattern to follow.
+
+d) Notable risks / edge cases
+
+1. Dashboard polling could spam toasts
+- `checkExpirationNotifications()` runs inside package load flow.
+- If polling is added naively, expiration toasts could repeat or localStorage notification keys could churn unexpectedly.
+
+2. Dashboard chart semantics
+- `statisticsFlows` appears to be a snapshot list, not a stream API.
+- Frequent polling may redraw aggressively and may need dedupe/staleness handling.
+
+3. Node websocket auth/security
+- Realtime URL sends token in query string (`secret=${getToken()}`) in:
+  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node/use-node-realtime.ts`
+- Any changes should be careful not to break backend expectations.
+
+4. Realtime/local state merge complexity
+- `loadNodes()` normalizes nodes and clears `systemInfo`.
+- If partial refetch is introduced, merging fetched node metadata with live websocket state must avoid wiping online metrics/progress.
+
+5. Batch APIs may not provide granular progress
+- Current batch helpers mostly return summary counts, not per-item progress.
+- True progress UI may require backend support, not only frontend work.
+
+6. Forward toggle consistency
+- `handleServiceToggle()` optimistically flips `serviceRunning` and later patches `status`.
+- If backend returns partial failure or delayed actual state, UI may drift until a refresh.
+
+7. User search behavior currently depends on backend pagination/search
+- Moving to fully instant local filtering may conflict with server-side pagination semantics and large datasets.
+
+Bottom line
+- Already present: async modal CRUD, no browser reloads, strong node realtime, optimistic forward toggle, instant search/filter on node/tunnel/forward pages.
+- Missing/partial for #276: dashboard traffic auto-refresh, consistent partial/local state updates after CRUD, batch progress UI outside node upgrade, and more unified instant-search UX on the user page.

+
+- `vite-frontend/src/pages/dashboard/use-dashboard-data.ts:55` 现在加入了 5 秒静默轮询、标签页可见性恢复刷新，以及更稳定的加载回调拆分，避免每次刷新都走整套初始化逻辑。
+- `vite-frontend/src/pages/dashboard/use-dashboard-data.ts:82` 把过期提醒的去重 key 改成基于用户/隧道到期信息的稳定标识，轮询刷新流量时不会反复弹 toast。
+- `vite-frontend/src/pages/node/use-node-realtime.ts:13` 补强了 WebSocket 重连策略：前几次按递增延迟重连，超过阈值后进入长间隔 fallback 模式，而不是彻底停掉。
+- `vite-frontend/src/pages/node.tsx:68` 增加了节点列表 merge 逻辑；fallback 刷新时会保留已有 `systemInfo`、升级/复制/回退 loading 状态，避免列表刷新把实时信息清空。
+- `vite-frontend/src/pages/node.tsx:1160` 节点页断线提示现在会区分“正在重连”和“已切换为列表自动刷新兜底模式”。
+- `vite-frontend/src/vite-env.d.ts:4` 补上了 `VITE_API_BASE` 类型声明，顺手消掉这次构建会碰到的环境变量类型报错。
+- `plans/020-ajax-no-refresh-ux.md:19` 已把本次完成的 3 个 Phase 1 checklist 勾掉。
+
+验证情况：
+- 运行了 `cd vite-frontend && npm install`
+- 运行了 `cd vite-frontend && npm run build`
+- 前端构建已通过
+
+这次额外生成了依赖文件：
+- `vite-frontend/package-lock.json`
+
+下一步自然就是继续 Phase 2，把 `forward` / `tunnel` / `user` 的“操作后整页数据重拉”改成局部 patch。你要我继续的话，我建议从 `vite-frontend/src/pages/forward.tsx` 开始，因为它已经有一部分本地更新模式，改起来最顺。

+# 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）
+
+---
+
+## 任务清单
+
+### 1. 后端修改
+
+- [x] **1.1 移除非管理员 inPort 权限限制**
+  - 文件: `go-backend/internal/http/handler/mutations.go`
+  - 位置: `forwardCreate` 函数 (约 L1156-1167)
+  - 位置: `forwardUpdate` 函数 (约 L1279-1291)
+  - 操作: 删除 `roleID != 0` 时阻止 inPort 设置的逻辑
+  - 状态: 代码中已无 inPort 权限限制
+
+- [x] **1.2 添加本地节点端口范围验证函数**
+  - 文件: `go-backend/internal/http/handler/mutations.go`
+  - 新增函数: `validateLocalNodePort(node *nodeRecord, port int) error`
+  - 逻辑: 使用 `parsePortRangeSpec` 解析端口范围，验证 port 是否在范围内
+  - 状态: 函数已存在于 L3517-3533
+
+- [x] **1.3 修改 forwardCreate 端口验证**
+  - 文件: `go-backend/internal/http/handler/mutations.go`
+  - 位置: `forwardCreate` 中 entry nodes 遍历处 (约 L1188-1197)
+  - 操作: 
+    - 对远程节点使用现有 `validateRemoteNodePort`
+    - 对本地节点使用新的 `validateLocalNodePort`
+    - 若用户指定的端口超出节点范围，返回错误提示
+  - 状态: 已实现
+
+- [x] **1.4 修改 forwardUpdate 端口验证**
+  - 文件: `go-backend/internal/http/handler/mutations.go`
+  - 位置: `forwardUpdate` 中 entry nodes 遍历处 (约 L1326-1335)
+  - 操作: 同 1.3，添加本地节点端口范围验证
+  - 状态: 已实现
+
+- [x] **1.5 `ListUserAccessibleTunnels` 添加端口范围信息**
+  - 文件: `go-backend/internal/store/repo/repository.go`
+  - 位置: L751-775
+  - 操作:
+    - 查询隧道关联的入口节点 (通过 `chain_tunnel` 表 `chain_type=1`)
+    - 获取入口节点的端口范围 (`node.port` 字段)
+    - 使用 `parsePortRangeSpec` 解析并计算 min/max
+    - 在返回的 map 中添加 `portRangeMin` 和 `portRangeMax` 字段
+  - 状态: 已实现
+
+- [x] **1.6 `ListEnabledTunnelSummaries` 添加端口范围信息**
+  - 文件: `go-backend/internal/store/repo/repository.go`
+  - 位置: L777-796
+  - 操作: 同 1.5，为管理员视图也提供端口范围信息
+  - 状态: 已实现
+
+### 2. 前端修改
+
+- [x] **2.1 为所有用户显示 inPort 输入框**
+  - 文件: `vite-frontend/src/pages/forward.tsx`
+  - 位置: 约 L4350-4369
+  - 操作: 移除 `{isAdmin && (` 条件包装，改为所有用户可见
+  - 状态: 已实现
+
+- [x] **2.2 提交时包含 inPort（非仅管理员）**
+  - 文件: `vite-frontend/src/pages/forward.tsx`
+  - 位置: `handleSave` 函数 (约 L1435, L1447)
+  - 操作: 移除 `...(isAdmin ? { inPort: form.inPort } : {})` 条件，直接包含 inPort
+  - 状态: 已实现
+
+- [x] **2.3 更新 Tunnel 接口添加 portRangeMin/Max**
+  - 文件: `vite-frontend/src/pages/forward.tsx`
+  - 位置: L123-131
+  - 操作: 添加 `portRangeMin?: number; portRangeMax?: number;`
+  - 状态: 已实现
+
+- [x] **2.4 inPort 输入框显示端口范围提示**
+  - 文件: `vite-frontend/src/pages/forward.tsx`
+  - 位置: L4350-4369
+  - 操作: 
+    - 基于 `form.tunnelId` 获取当前隧道的端口范围
+    - 在 Input 的 `description` 中显示提示，如: `"指定入口端口，留空自动分配 (允许范围: 10000-20000)"`
+  - 状态: 已实现
+
+- [x] **2.5 前端端口范围验证**
+  - 文件: `vite-frontend/src/pages/forward.tsx`
+  - 位置: 验证函数 (L1271-1279)
+  - 操作: 前端也做范围预检查，超出范围时显示错误
+  - 状态: 已实现并修复语法错误
+
+### 3. 测试修改
+
+- [x] **3.1 更新权限测试**
+  - 文件: `go-backend/tests/contract/forward_contract_test.go`
+  - 位置: L1001-1119
+  - 操作:
+    - 修改 "non-admin cannot set inPort" 测试为允许设置
+    - 新增 "non-admin inPort within range" 测试（通过）
+    - 新增 "non-admin inPort out of range" 测试（失败）
+  - 状态: 已更新
+
+- [x] **3.2 新增端口范围验证测试**
+  - 文件: `go-backend/tests/contract/forward_contract_test.go`
+  - 操作:
+    - 测试本地节点端口范围验证
+    - 测试远程节点端口范围验证（已有 `validateRemoteNodePort` 相关测试可参考）
+  - 状态: 已添加

+
+## 验收标准
+
+1. ✅ 普通用户可以在创建转发时指定 inPort
+2. ✅ 普通用户可以在编辑转发时修改 inPort
+3. ✅ 指定的端口必须在节点端口范围内，否则返回错误
+4. ✅ 留空 inPort 时行为不变（自动分配）
+5. ✅ 前端显示端口范围提示
+6. ✅ 所有合约测试通过
+
+---
+
+## 实施总结
+
+该计划的大部分代码已在之前的开发中实现。本次实施主要完成了以下工作：
+
+1. **修复前端验证代码语法错误** - `forward.tsx` 中 `validateForm` 函数的端口范围验证代码存在语法错误，已修复
+2. **更新测试用例** - 将原本期望权限拒绝的测试改为端口范围验证测试，并修正了测试中使用的端口号

+
+## Checklist
+
+- [x] Confirm forward update failure path caused by delete fallback short-circuiting on the first not-found service name.
+- [x] Update forward service deletion logic to continue across all candidate runtime names until one is actually deleted or every candidate is exhausted.
+- [x] Add regression tests covering mixed not-found and legacy-name delete recovery during forward control/update flows.
+- [x] Run focused backend handler tests and record the result.
+
+## Test Record
+
+- Command: `cd go-backend && go test ./internal/http/handler/...`
+- Result: passed.

+## 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`.
+
+## Rollout Notes
+
+- 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.

+# 028 - Sync Forward Ports On Tunnel Entry Change

+# Issue 291 Tunnel Traffic Quota Plan
+
+- [x] Confirm quota semantics with issue owner: use existing billed traffic accounting (`traffic_ratio * tunnel.flow`), overage disables the tunnel and pauses active forwards, reset re-enables the tunnel and auto-resumes affected forwards.
+- [x] Extend backend schema in `go-backend/internal/store/model/model.go` with a dedicated tunnel quota persistence model that stores per-tunnel daily/monthly limits, current billed usage, rollover keys, and quota-disable metadata in a SQLite/PostgreSQL-safe shape.
+- [x] Add repository support in `go-backend/internal/store/repo/` for reading quota settings, atomically rolling day/month windows forward, incrementing billed tunnel usage from flow uploads, checking overage state, marking quota-triggered disable state, clearing usage on manual reset, and listing quota data alongside tunnels.
+- [x] Wire billed tunnel usage accumulation into `go-backend/internal/http/handler/flow_policy.go` so each node-reported flow item updates both existing user/user_tunnel counters and the tunnel quota counters using the current billed flow scaling path.
+- [x] Implement quota enforcement in backend handlers: when a tunnel crosses quota, set `tunnel.status = 0`, mark it as quota-disabled, pause all active forwards under that tunnel, and persist enough state to distinguish quota shutdown from manual disable.
+- [x] Block forward lifecycle operations against quota-disabled or already-over-quota tunnels in `go-backend/internal/http/handler/mutations.go` and related flow-policy checks so create/resume paths fail fast with explicit quota messages.
+- [x] Extend the maintenance/reset job in `go-backend/internal/http/handler/jobs.go` to perform daily and monthly quota rollover resets, clear quota-disable flags when limits reset, and auto-resume forwards that were paused by quota enforcement.
+- [x] Add manual quota reset API support under `go-backend/internal/http/handler/handler.go` and `go-backend/internal/http/handler/mutations.go` for daily/monthly/all reset scopes, with backend logic to clear counters, re-enable the tunnel, and auto-resume forwards.
+- [x] Extend tunnel API payloads in `go-backend/internal/store/repo/repository.go` and handler responses so `tunnel/list` and `tunnel/get` expose quota configuration, usage, reset window state, and quota-disable reason without conflicting with existing `flow` semantics.
+- [x] Update backup/import-export structs and repository export/import helpers in `go-backend/internal/store/model/model.go` and `go-backend/internal/store/repo/repository.go` so tunnel quota configuration is preserved across backup/restore; only persist configuration and disable metadata, not stale rolling usage, unless implementation proves current-period restoration is necessary.
+- [x] Update frontend tunnel types and API helpers in `vite-frontend/src/api/types.ts`, `vite-frontend/src/types/index.ts`, and `vite-frontend/src/api/index.ts` to accept and submit tunnel quota fields with safe defaults for older payloads.
+- [x] Add quota management UI to `vite-frontend/src/pages/tunnel.tsx` for daily/monthly quota inputs, billed usage display, over-quota status, reset actions, and clear tunnel-disabled messaging while preserving existing layout and form conventions.
+- [x] Verify behavior with backend contract coverage in `go-backend/tests/contract/` for over-quota disable, create/resume blocking, scheduled reset rollover, manual reset, and auto-resume after reset; run targeted backend tests plus a frontend build validation after implementation. (`go test ./internal/http/handler/... ./tests/contract/...` passed; frontend `npm run build` is currently blocked by missing local dependencies/types in this environment.)
