+# Commercial White-Label Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Allow users with a valid license key to activate commercial white-label features, enabling them to remove FLVX branding and use their own app name, logos, and footer.
+**Architecture:** Backend API handles license validation and stores state (`is_commercial`). Both frontend and backend check this state to conditionally render or allow modifications to brand config.
+**Tech Stack:** Go (Backend API), React + Vite (Frontend UI).
+
+---
+
+### Task 1: Backend License Activation Endpoint
+
+**Files:**
+- Modify: `go-backend/internal/http/handler/handler.go`
+
+- [ ] **Step 1: Add license request struct**
+Add the `licenseActivateRequest` struct in `handler.go`.
+
+```go
+type licenseActivateRequest struct {
+	LicenseKey string `json:"license_key"`
+}
+```
+
+- [ ] **Step 2: Add `licenseActivate` handler method**
+Add the method to validate the key in `handler.go`.
+
+```go
+func (h *Handler) licenseActivate(w http.ResponseWriter, r *http.Request) {
+	if r.Method != http.MethodPost {
+		response.WriteJSON(w, response.ErrDefault("请求失败"))
+		return
+	}
+
+	var req licenseActivateRequest
+	if err := decodeJSON(r.Body, &req); err != nil {
+		response.WriteJSON(w, response.ErrDefault("授权码不能为空"))
+		return
+	}
+	
+	key := strings.TrimSpace(req.LicenseKey)
+	if !strings.HasPrefix(key, "FLVX-") {
+		response.WriteJSON(w, response.ErrDefault("无效的商业授权码"))
+		return
+	}
+
+	now := time.Now().UnixMilli()
+	if err := h.repo.UpsertConfig("license_key", key, now); err != nil {
+		response.WriteJSON(w, response.Err(-2, err.Error()))
+		return
+	}
+	if err := h.repo.UpsertConfig("is_commercial", "true", now); err != nil {
+		response.WriteJSON(w, response.Err(-2, err.Error()))
+		return
+	}
+
+	response.WriteJSON(w, response.OKEmpty())
+}
+```
+
+- [ ] **Step 3: Register the route**
+In `handler.go` inside `Register(mux *http.ServeMux)`, add the route.
+
+```go
+	mux.HandleFunc("/api/v1/license/activate", h.licenseActivate)
+```
+
+- [ ] **Step 4: Commit**
+```bash
+git add go-backend/internal/http/handler/handler.go
+git commit -m "feat: add license activation endpoint"
+```
+
+### Task 2: Backend Config Update Validation
+
+**Files:**
+- Modify: `go-backend/internal/http/handler/handler.go`
+
+- [ ] **Step 1: Add permission check in `updateConfigs`**
+In `updateConfigs`, fetch `isCommercial := h.repo.GetConfig("is_commercial")`. Inside the loop, check if the user is trying to update protected keys.
+
+```go
+	isCommercial, _ := h.repo.GetConfig("is_commercial")
+	protectedKeys := map[string]bool{
+		"app_name":          true,
+		"app_logo":          true,
+		"app_favicon":       true,
+		"hide_footer_brand": true,
+	}
+```
+Inside `for k, v := range payload`:
+```go
+		if protectedKeys[key] && isCommercial.Value != "true" {
+			response.WriteJSON(w, response.ErrDefault("需要商业版授权"))
+			return
+		}
+```
+
+- [ ] **Step 2: Add permission check in `updateSingleConfig`**
+In `updateSingleConfig`, do the same check before calling `normalizeAndValidateConfigValue`.
+
+```go
+	isCommercial, _ := h.repo.GetConfig("is_commercial")
+	if (name == "app_name" || name == "app_logo" || name == "app_favicon" || name == "hide_footer_brand") && isCommercial.Value != "true" {
+		response.WriteJSON(w, response.ErrDefault("需要商业版授权"))
+		return
+	}
+```
+
+- [ ] **Step 3: Commit**
+```bash
+git add go-backend/internal/http/handler/handler.go
+git commit -m "feat: add authorization check for commercial config keys"
+```
+
+### Task 3: Frontend API & Site Config Update
+
+**Files:**
+- Modify: `vite-frontend/src/api/index.ts`
+- Modify: `vite-frontend/src/config/site.ts`
+
+- [ ] **Step 1: Add `activateLicense` API**
+In `vite-frontend/src/api/index.ts`:
+
+```typescript
+export const activateLicense = (licenseKey: string) =>
+  Network.post("/license/activate", { license_key: licenseKey });
+```
+
+- [ ] **Step 2: Update `siteConfig` defaults**
+In `vite-frontend/src/config/site.ts`, inside `getInitialConfig()`, add properties.
+
+```typescript
+    app_logo: cachedAppLogo,
+    app_favicon: cachedAppFavicon,
+    is_commercial: configCache.get("is_commercial") === "true",
+    hide_footer_brand: configCache.get("hide_footer_brand") === "true",
+```
+
+- [ ] **Step 3: Update `updateSiteConfig`**
+In `updateSiteConfig` inside `site.ts`, extract and update `is_commercial` and `hide_footer_brand`.
+
+```typescript
+  const isCommercial = resolvedConfigMap.is_commercial === "true";
+  const hideFooterBrand = resolvedConfigMap.hide_footer_brand === "true";
+  siteConfig.is_commercial = isCommercial;
+  siteConfig.hide_footer_brand = hideFooterBrand;
+```
+
+- [ ] **Step 4: Commit**
+```bash
+git add vite-frontend/src/api/index.ts vite-frontend/src/config/site.ts
+git commit -m "feat: add frontend api and update site config state for license"
+```
+
+### Task 4: Frontend Footer Component Update
+
+**Files:**
+- Modify: `vite-frontend/src/components/version-footer.tsx`
+
+- [ ] **Step 1: Conditionally hide "Powered by FLVX"**
+In the render block, wrap the `Powered by FLVX` text.
+
+```tsx
+      {siteConfig.hide_footer_brand !== true && (
+        <p className={poweredClassName}>
+          Powered by{" "}
+          <a
+            className="text-gray-500 dark:text-gray-400 hover:text-gray-600 dark:hover:text-gray-300 transition-colors"
+            href={siteConfig.github_repo}
+            rel="noopener noreferrer"
+            target="_blank"
+          >
+            FLVX
+          </a>
+        </p>
+      )}
+```
+
+- [ ] **Step 2: Commit**
+```bash
+git add vite-frontend/src/components/version-footer.tsx
+git commit -m "feat: conditionally hide flvx footer brand"
+```
+
+### Task 5: Frontend Settings Page UI Update
+
+**Files:**
+- Modify: `vite-frontend/src/pages/config.tsx`
+
+- [ ] **Step 1: Add config keys to initialization**
+In `getInitialConfigs`, add `"is_commercial"` and `"hide_footer_brand"` to `configKeys`.
+
+- [ ] **Step 2: Add `hide_footer_brand` switch field**
+Add it to the `CONFIG_ITEMS` array.
+
+```typescript
+  {
+    key: "hide_footer_brand",
+    label: "隐藏页面底部 FLVX 版权信息",
+    description: "需商业版授权才能生效",
+    type: "switch",
+  },
+```
+
+- [ ] **Step 3: Add license activation UI**
+Above the System Config Card (near `value="configs"`), add a new `Card` for "商业版授权". You will need a local state `licenseKey` and an `handleActivateLicense` function that calls `activateLicense(licenseKey)` and refetches configs on success. 
+
+- [ ] **Step 4: Disable brand settings when not commercial**
+In `renderConfigItem`, compute `isDisabled` and pass it to the `<Input>`, `<Switch>`, and `BrandUploading` UI. Update the logic to disable modifications and add a lock icon or a tooltip explaining that a commercial license is required.
+
+```typescript
+const isCommercialDisabled = ["app_name", "app_logo", "app_favicon", "hide_footer_brand"].includes(item.key) && configs.is_commercial !== "true";
+```
+
+- [ ] **Step 5: Commit**
+```bash
+git add vite-frontend/src/pages/config.tsx
+git commit -m "feat: ui settings for commercial white-label and license activation"

+# Commercial White-Label (Keygen) Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Implement Keygen.sh license activation and periodic validation to manage commercial white-label features, replacing the temporary mock logic.
+**Architecture:** The backend generates a machine fingerprint, validates the license via the Keygen.sh API, and creates a machine associated with the license. A periodic job verifies the license status to support remote revocation.
+**Tech Stack:** Go (Backend API), Keygen.sh API.
+
+---
+
+### Task 1: Generate and Store Machine Fingerprint
+
+**Files:**
+- Modify: `go-backend/internal/http/handler/handler.go`
+
+- [ ] **Step 1: Add `getOrCreateMachineFingerprint` helper function**
+Add a helper function in `handler.go` (or a dedicated license file) to get or generate the machine fingerprint. Use `github.com/google/uuid`.
+
+```go
+import "github.com/google/uuid"
+
+func (h *Handler) getOrCreateMachineFingerprint() (string, error) {
+	fp, _ := h.repo.GetViteConfigValue("machine_fingerprint")
+	if fp != "" {
+		return fp, nil
+	}
+
+	newFp := uuid.New().String()
+	now := time.Now().UnixMilli()
+	if err := h.repo.UpsertConfig("machine_fingerprint", newFp, now); err != nil {
+		return "", err
+	}
+	return newFp, nil
+}
+```
+
+- [ ] **Step 2: Commit**
+```bash
+git add go-backend/internal/http/handler/handler.go
+git commit -m "feat: add machine fingerprint generation"
+```
+
+### Task 2: Create Keygen Client Package
+
+**Files:**
+- Create: `go-backend/internal/license/keygen.go`
+
+- [ ] **Step 1: Create Keygen client structs and interface**
+Create the file and define the request/response structs for Keygen's `/licenses/actions/validate-key` and `/machines` endpoints. Also define an interface for the client.
+
+```go
+package license
+
+import (
+	"bytes"
+	"encoding/json"
+	"fmt"
+	"io"
+	"net/http"
+	"time"
+)
+
+type KeygenClient struct {
+	AccountID string
+	Token     string
+	HTTPClient *http.Client
+}
+
+func NewKeygenClient(accountID, token string) *KeygenClient {
+	return &KeygenClient{
+		AccountID: accountID,
+		Token:     token,
+		HTTPClient: &http.Client{Timeout: 10 * time.Second},
+	}
+}
+
+type ValidateResponse struct {
+	Meta struct {
+		Valid bool   `json:"valid"`
+		Code  string `json:"code"`
+	} `json:"meta"`
+	Data struct {
+		ID string `json:"id"`
+	} `json:"data"`
+}
+
+type ActivateMachineRequest struct {
+	Data struct {
+		Type       string `json:"type"`
+		Attributes struct {
+			Fingerprint string `json:"fingerprint"`
+		} `json:"attributes"`
+		Relationships struct {
+			License struct {
+				Data struct {
+					Type string `json:"type"`
+					ID   string `json:"id"`
+				} `json:"data"`
+			} `json:"license"`
+		} `json:"relationships"`
+	} `json:"data"`
+}
+```
+
+- [ ] **Step 2: Implement `ValidateKey`**
+Add the `ValidateKey` method.
+
+```go
+func (c *KeygenClient) ValidateKey(key string) (*ValidateResponse, error) {
+	url := fmt.Sprintf("https://api.keygen.sh/v1/accounts/%s/licenses/actions/validate-key", c.AccountID)
+	
+	reqBody := map[string]interface{}{
+		"meta": map[string]string{
+			"key": key,
+		},
+	}
+	bodyBytes, _ := json.Marshal(reqBody)
+
+	req, _ := http.NewRequest(http.MethodPost, url, bytes.NewBuffer(bodyBytes))
+	req.Header.Set("Content-Type", "application/json")
+	req.Header.Set("Accept", "application/json")

+	if err := json.NewDecoder(resp.Body).Decode(&valResp); err != nil {
+		return nil, err
+	}
+
+	return &valResp, nil
+}
+```
+
+- [ ] **Step 3: Implement `ActivateMachine`**
+Add the `ActivateMachine` method.
+
+```go
+func (c *KeygenClient) ActivateMachine(licenseID, fingerprint string) error {
+	url := fmt.Sprintf("https://api.keygen.sh/v1/accounts/%s/machines", c.AccountID)

+	}
+
+	body, _ := io.ReadAll(resp.Body)
+	return fmt.Errorf("failed to activate machine: status %d, response: %s", resp.StatusCode, string(body))

+### Task 3: Integrate Keygen into License Activation Endpoint
+
+**Files:**
+- Modify: `go-backend/internal/http/handler/handler.go`
+
+- [ ] **Step 1: Update `licenseActivate` logic**
+Modify `licenseActivate` to use the Keygen client instead of the mock logic. Note: For this implementation, we will use an environment variable `KEYGEN_ACCOUNT_ID`. We can use `os.Getenv` directly for simplicity, or hardcode a fallback if not present.
+
+```go
+import (
+	"go-backend/internal/license"
+	"os"
+)
+
+func (h *Handler) licenseActivate(w http.ResponseWriter, r *http.Request) {
+	// ... (keep request parsing)

+	}
+
+	fingerprint, err := h.getOrCreateMachineFingerprint()
+	if err != nil {
+		response.WriteJSON(w, response.ErrDefault("生成设备指纹失败"))
+		return
+	}
+
+	client := license.NewKeygenClient(accountID, "") // Token may be optional for validate-key depending on policy, or can be passed if needed
+	
+	valResp, err := client.ValidateKey(key)
+	if err != nil {
+		response.WriteJSON(w, response.ErrDefault("连接授权服务器失败: "+err.Error()))
+		return
+	}
+
+	if !valResp.Meta.Valid {
+		response.WriteJSON(w, response.ErrDefault("授权码无效或已过期 (Code: "+valResp.Meta.Code+")"))
+		return
+	}
+
+	// Try to activate machine
+	err = client.ActivateMachine(valResp.Data.ID, fingerprint)
+	if err != nil {
+		response.WriteJSON(w, response.ErrDefault("设备绑定失败: "+err.Error()))
+		return
+	}
+
+	now := time.Now().UnixMilli()
+	if err := h.repo.UpsertConfig("license_key", key, now); err != nil {
+		response.WriteJSON(w, response.Err(-2, err.Error()))
+		return
+	}
+	if err := h.repo.UpsertConfig("is_commercial", "true", now); err != nil {
+		response.WriteJSON(w, response.Err(-2, err.Error()))
+		return
+	}
+
+	response.WriteJSON(w, response.OKEmpty())
+}

+
+### Task 4: Add Periodic License Validation Job
+
+**Files:**
+- Modify: `go-backend/internal/http/handler/jobs.go`
+- Modify: `go-backend/internal/http/handler/handler.go`
+
+- [ ] **Step 1: Add `validateLicenseJob` function in `jobs.go`**
+Create a new function that performs the background validation.
+
+```go
+import "os"
+
+func (h *Handler) validateLicenseJob() {
+	if h == nil || h.repo == nil {
+		return
+	}
+
+	accountID := os.Getenv("KEYGEN_ACCOUNT_ID")
+	if accountID == "" {
+		return // Skip if not configured
+	}
+
+	key, _ := h.repo.GetViteConfigValue("license_key")
+	isCommercial, _ := h.repo.GetViteConfigValue("is_commercial")
+
+	if key == "" || isCommercial != "true" {
+		return // Nothing to validate
+	}
+
+	client := license.NewKeygenClient(accountID, "")
+	valResp, err := client.ValidateKey(key)
+	
+	if err != nil {
+		// Network error or timeout. We implement a grace period by NOT revoking immediately here.
+		// In a production system, you might count consecutive failures.
+		// For now, we skip revocation on network errors.
+		return

+	if !valResp.Meta.Valid {
+		// License is invalid (e.g., revoked, suspended, expired). Downgrade the system.
+		now := time.Now().UnixMilli()
+		_ = h.repo.UpsertConfig("is_commercial", "false", now)
+		// We could optionally clear brand configs here, or just let them be disabled in UI
+	}
+}
+```
+
+- [ ] **Step 2: Register the job in `RunJobs`**
+In `handler.go` or `jobs.go`, wherever the periodic cron jobs are registered (usually `go h.runJobs()`), ensure `validateLicenseJob` is called periodically (e.g., every 12 hours). Look for `h.startCronJobs()` or similar in `handler.go`. 
+
+If a central `RunJobs` loop exists in `jobs.go` (like a `for` loop with a `time.Ticker`), add it there. If not, create a simple goroutine in `Register` or `NewHandler`.
+
+*Assuming there's a `startJobs` or `Init` block in `handler.go`:*
+```go
+// Inside handler initialization or Register:
+go func() {
+	ticker := time.NewTicker(12 * time.Hour)
+	defer ticker.Stop()
+	for {
+		select {
+		case <-ticker.C:
+			h.validateLicenseJob()
+		}
+	}
+}()

+# Announcement Popup Notification Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add a popup modal for announcements that automatically shows to users when a new or updated announcement is published.
+
+**Architecture:** We will modify the Go backend to return `update_time` along with the announcement data. In the Vite frontend, we will store the user's `flvx_announcement_seen_time` in `localStorage`. If the fetched `update_time` is greater than the stored timestamp, we trigger a NextUI Modal displaying the announcement content.
+
+**Tech Stack:** Go, Vite, React, TailwindCSS, NextUI.

+### Task 4: Integrate Modal State in Dashboard Custom Hook
+
+**Files:**
+- Modify: `vite-frontend/src/pages/dashboard/use-dashboard-data.ts`
+
+- [ ] **Step 1: Update the hook return type interface**
+
+At the top of `vite-frontend/src/pages/dashboard/use-dashboard-data.ts` where `DashboardData` is or similar, add the new properties (if it uses an explicit return type). If it's inferred, skip this. Wait, let's check the code:
+
+```typescript
+  isAnnouncementModalOpen: boolean;
+  setIsAnnouncementModalOpen: (isOpen: boolean) => void;
+  dismissAnnouncementModal: () => void;
+```
+Ensure they are added to the returned object at the bottom of the `useDashboardData` hook.
+
+Find the `const loadAnnouncement` function. 
+
+- [ ] **Step 2: Write the minimal implementation**
+
+First, add state at the top of the hook:
+```typescript
+  const [isAnnouncementModalOpen, setIsAnnouncementModalOpen] = useState(false);
+```
+
+Then, modify the `loadAnnouncement` logic inside `useDashboardData`:
+```typescript
+      if (res.code === 0 && res.data && res.data.enabled === 1) {
+        setAnnouncement(res.data);
+        
+        try {
+          const storedTimeStr = localStorage.getItem("flvx_announcement_seen_time");
+          const storedTime = storedTimeStr ? parseInt(storedTimeStr, 10) : 0;
+          const updateTime = res.data.update_time || 0;
+          
+          if (updateTime > storedTime) {
+            setIsAnnouncementModalOpen(true);
+          }
+        } catch (err) {
+          console.warn("Failed to read localStorage for announcement state", err);
+          setIsAnnouncementModalOpen(true);
+        }
+      } else {
+        setAnnouncement(null);
+      }
+```
+
+Add the dismiss handler inside the hook:
+```typescript
+  const dismissAnnouncementModal = useCallback(() => {
+    setIsAnnouncementModalOpen(false);
+    if (announcement && announcement.update_time) {
+      try {
+        localStorage.setItem("flvx_announcement_seen_time", announcement.update_time.toString());
+      } catch (err) {
+        console.warn("Failed to set localStorage for announcement state", err);
+      }
+    }
+  }, [announcement]);
+```
+
+Ensure these are included in the return object of the hook:
+```typescript
+    isAnnouncementModalOpen,
+    setIsAnnouncementModalOpen,
+    dismissAnnouncementModal,
+```
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add vite-frontend/src/pages/dashboard/use-dashboard-data.ts
+git commit -m "feat(ui): manage announcement modal state in dashboard hook"
+```
+

+
+### Task 5: Add Modal to Dashboard Layout
+
+**Files:**
+- Modify: `vite-frontend/src/pages/dashboard.tsx`
+
+- [ ] **Step 1: Write the minimal implementation**
+
+Import the modal component at the top:
+```tsx
+import { AnnouncementModal } from "@/pages/dashboard/components/announcement-modal";
+```
+
+Add the new properties to the destructured `useDashboardData` object:
+```tsx
+    isAnnouncementModalOpen,
+    setIsAnnouncementModalOpen,
+    dismissAnnouncementModal,
+```
+
+Add the modal instance near the end of the dashboard rendering (just below `{announcement && <AnnouncementBanner ... />}` or inside the main `<div>`):
+```tsx
+      {announcement && (
+        <AnnouncementModal
+          announcement={announcement}

+# FLVX 商业版白标授权功能设计方案
+
+## 1. 目标
+通过在设置面板中引入商业版激活码（License Key），允许已授权的用户去除前端页面的 FLVX 品牌标识，并使用自己的 App Name、Logo、Favicon 和隐藏版权信息，从而实现“白标”定制。
+
+## 2. 功能范围
+*   **授权校验（服务端）**：提供一个激活码输入与验证的接口。初始版本采用**在线 Mock 验证**，后续可通过替换验证服务器地址实现真实的在线发卡与吊销逻辑。
+*   **配置存储（服务端）**：一旦授权成功，在数据库（如 `vite_config` 或现有的配置表）中记录授权状态（例如 `license_key`、`is_commercial` 等），并放开商业白标相关字段的写入权限（`app_name`, `app_logo`, `app_favicon`, `hide_footer_brand`）。
+*   **权限拦截（服务端）**：拦截未授权用户的请求，禁止他们更新相关的品牌字段。
+*   **前端 UI（客户端）**：
+    *   在配置页面（或单独的“授权/个性化” Tab）提供激活码输入框。
+    *   如果未激活：界面仅展示默认品牌配置，并提示“需要商业授权以解锁自定义品牌”。
+    *   如果已激活：展示站名、Logo、Favicon 的上传和替换表单，提供隐藏“Powered by FLVX”脚标的开关。
+
+## 3. 架构设计
+
+### 3.1 数据库/配置结构
+扩展配置系统中的以下字段：
+*   `license_key` (String)：存储用户激活的商业版密钥。
+*   `is_commercial` (String/Boolean)：标识是否为合法的商业授权状态（"true" 或 "false"）。
+*   `hide_footer_brand` (String/Boolean)：是否隐藏底部的 FLVX 信息。
+
+注意：现有的 `app_name`, `app_logo`, `app_favicon` 字段将收紧修改权限。
+
+### 3.2 服务端 API 变更
+*   **新增 API `POST /api/license/activate` (或将逻辑集成到现有配置修改接口)**：
+    *   接收 `{ "license_key": "FLVX-xxxx" }`。
+    *   **Mock 逻辑**：如果是 `FLVX-` 开头则视为合法。
+    *   合法则更新系统配置，设置 `license_key` 并将状态标为 `is_commercial: "true"`。
+*   **修改 API 权限校验（如保存系统设置的接口）**：
+    *   当接收到更新 `app_name`、`app_logo`、`app_favicon`、`hide_footer_brand` 的请求时，检查当前系统中的 `is_commercial` 状态。
+    *   如果未授权且尝试修改白标字段，返回错误（如 `403 Forbidden`）提示需要商业授权。
+
+### 3.3 前端设计
+*   **授权卡片**：在全局设置（Settings / Config）页加入「商业版授权」或「个性化」区块。
+*   **表单按需显示**：使用配置中的 `is_commercial === "true"` 来控制相关表单组件的展示：
+    *   如果未授权，白标字段（Logo、Favicon、App Name、Hide Footer）不可修改（呈 Disabled）或覆盖了一层“锁”图标。
+    *   底部 Footer 组件读取 `hide_footer_brand === "true"` 决定是否渲染 `Powered by FLVX`。
+*   **全局状态同步**：当用户激活或上传完 Logo 后，通过现有的 `syncLogo` / `syncFavicon` 等机制全局刷新外观。
+
+## 4. 安全与降级
+*   **本地缓存失效**：如果后台在线验证服务器（未来）判断该 key 被吊销，可以在后续获取 config 的接口中重置白标配置为空，强制回退到默认 FLVX 主题。
+*   **接口防绕过**：所有跟商业字段相关的变更，必须经过后端 API 的鉴权，确保纯前端绕过是无效的。
+
+## 5. 测试策略
+1.  **输入非法激活码**，提示错误，白标设置项仍被锁定。
+2.  **输入合法激活码 (`FLVX-...`)**，提示成功，白标设置项解锁。
+3.  **成功后上传 Logo 和修改站名**，刷新页面，前端应正常应用新配置且没有 FLVX 标记。
+4.  **接口测试**：在未授权状态下，尝试强行通过 API 更新 `app_logo`，接口应返回权限不足。

+# FLVX 商业版 Keygen.sh 授权集成设计方案
+
+## 1. 目标
+使用 [Keygen.sh](https://keygen.sh/) 替换当前 FLVX 中基于 Mock 的商业版授权验证逻辑。通过接入 Keygen.sh，实现安全、可控的许可证分发、设备绑定（防止一码多用）、定期验证以及远程吊销功能，为 FLVX 的商业化白标功能提供生产级支持。
+
+## 2. Keygen.sh 核心概念映射
+*   **Account (账户)**：您在 Keygen 注册的商户账号。
+*   **Product (产品)**：在 Keygen 中创建一个名为 `FLVX Panel` 的产品。
+*   **Policy (策略)**：定义授权规则。例如，创建一个 `White-Label Policy`，限制每个 License 只能绑定 **1 个 Machine**（即一个 FLVX 面板实例），并可配置有效期（如按年订阅或永久有效）。
+*   **License (许可证)**：发给客户的激活码（Key），格式可自定义（如 `FLVX-XXXX-XXXX`）。
+*   **Machine (机器/设备)**：运行 FLVX 的具体服务器或面板实例。为了防止一码多开，FLVX 激活时需要向 Keygen 注册一台 Machine。
+
+## 3. 架构设计与集成流程
+
+### 3.1 唯一设备标识 (Machine Fingerprint)
+为了在 Keygen 中标识不同的 FLVX 面板，FLVX 后端需要生成并持久化一个唯一的机器指纹（Fingerprint）。
+*   **生成时机**：FLVX 首次启动或首次激活时，生成一个 UUID v4。
+*   **存储**：保存在数据库 `vite_config` 表中，键名为 `machine_fingerprint`。
+
+### 3.2 激活流程 (License Activation)
+当用户在前端输入激活码并点击“激活”时：
+1.  **FLVX 后端验证 Key**：调用 Keygen API `POST /v1/accounts/{account}/licenses/actions/validate-key`，传入 `key`。
+2.  **检查 License 状态**：如果返回 `valid: true`，说明 License 合法且未过期。
+3.  **激活 Machine (设备绑定)**：
+    *   调用 Keygen API `POST /v1/accounts/{account}/machines`。
+    *   关联刚才验证的 `licenseId`，并传入 FLVX 的 `machine_fingerprint`。
+    *   *异常处理*：如果该 License 已绑定了其他 Machine（达到 Policy 上限），Keygen 会报错，FLVX 后端需返回“该授权码已在其他设备使用”。
+4.  **持久化状态**：激活成功后，在本地数据库保存 `license_key`、`is_commercial: "true"`，以及从 Keygen 返回的额外信息（如过期时间 `license_expiry`）。
+
+### 3.3 定期心跳与验证 (Periodic Validation)
+为了防止用户激活后断网或通过修改数据库绕过，以及实现**远程吊销**：
+*   **定时任务**：FLVX 后端增加一个后台协程（如每天运行一次，或每 12 小时运行一次）。
+*   **验证逻辑**：调用 Keygen API 验证当前的 `license_key` 和 `machine_fingerprint`。
+*   **吊销/过期处理**：如果 Keygen 明确返回 License 已吊销（Suspended/Revoked/Banned）或已过期，或者当前 Machine 不再属于该 License，FLVX 后端需将 `is_commercial` 强制设为 `"false"`，并清空本地缓存，恢复官方品牌展示。
+*   **宽限期 (Grace Period)**：考虑到用户服务器可能偶尔网络不通，如果请求 Keygen 超时或失败，不应立刻吊销。可设置一个宽限期（如连续 3 天请求失败才降级）。
+
+## 4. 后端 API 改造计划 (`go-backend`)
+
+### 4.1 新增环境变量/配置
+*   `KEYGEN_ACCOUNT_ID`: 您的 Keygen 账户 ID（打包时可硬编码，或作为全局环境变量）。
+*   （可选）`KEYGEN_PRODUCT_TOKEN` 或仅使用 License Key 进行验证（取决于 Keygen 验证方式的选择，推荐直接使用 License Key 进行无状态验证）。
+
+### 4.2 改造 `/api/v1/license/activate`
+*   引入 HTTP 客户端向 `api.keygen.sh` 发起请求。
+*   实现上述提到的 Validate Key 和 Activate Machine 两步走逻辑。
+*   返回具体的错误信息给前端（例如：“授权码不存在”、“授权码已过期”、“激活设备数达上限”）。
+
+## 5. 前端改造计划 (`vite-frontend`)
+前端在目前的 UI 基础上几乎不需要大改，只需配合后端的增强：
+1.  **展示过期时间**：如果后端返回了 `license_expiry`，可以在“商业版授权”卡片中展示“授权有效期至：YYYY-MM-DD”。
+2.  **错误提示优化**：透传后端返回的 Keygen 验证错误，给予用户明确的指引。
+3.  **解绑/停用功能（可选）**：未来可增加“停用授权”按钮，调用后端接口在 Keygen 中删除 Machine 绑定，以便用户将 License 迁移到新的服务器。
+
+## 6. 实施步骤建议
+1.  在 Keygen.sh 注册账号，创建 Product 和 Policy，生成测试用的 License Key。
+2.  在 FLVX 的 `go-backend` 中新建一个 `pkg/keygen` 或 `internal/license` 包，封装 Keygen API 的调用（Validate, Activate Machine）。
+3.  修改现有的 `licenseActivate` 接口，接入真正的验证逻辑。
+4.  添加定期验证的 Cron Job。
+5.  测试激活、吊销、过期、断网等各种场景。

+# Announcement Popup Notification Design
+
+## Overview
+This feature implements a popup notification modal for important dashboard announcements to ensure users see them immediately, addressing GitHub Issue #169.
+
+## Requirements
+1. Automatic display of a popup modal when opening the dashboard page if a new/updated announcement exists.
+2. Includes a "Don't show again" option to remember the user's choice to dismiss it.
+3. Smart triggering: Only pops up for *new* or *updated* announcements.
+4. Support Markdown formatting for the announcement content.
+5. Retain the existing permanent top banner as a fallback.
+
+## Backend Changes (Go)
+The `/api/v1/announcement/get` API currently only returns `content` and `enabled`. It must be updated to return the timestamp of the last update to enable the frontend to detect changes.
+
+1.  **Repository (`internal/store/repo/repository.go`)**: Ensure `GetAnnouncement` retrieves `UpdatedTime` (or falls back to `CreatedTime`).
+2.  **Handler (`internal/http/handler/handler.go`)**: Modify `getAnnouncement` to include an `update_time` (int64) field in its JSON response.
+
+## Frontend Changes (Vite/React/Tailwind)
+1.  **API Interface (`src/api/index.ts`)**:
+    *   Update `AnnouncementData` to include `update_time: number`.
+2.  **Storage Mechanism**:
+    *   Use browser `localStorage` to persist the user's view state. Key: `flvx_announcement_seen_time`.
+3.  **UI Component (`AnnouncementModal`)**:
+    *   Create a new modal component for the dashboard.
+    *   The modal content will render the markdown of the announcement.
+    *   It will feature two primary actions:
+        *   **"Close"**: Closes the modal temporarily for this session (does NOT update `localStorage`). It will pop up again on the next page load.
+        *   **"Don't show again"**: Closes the modal AND sets `localStorage.setItem('flvx_announcement_seen_time', announcement.update_time)`.
+4.  **Integration (`src/pages/dashboard.tsx` & `use-dashboard-data.ts`)**:
+    *   Add state to manage the modal visibility (e.g., `isAnnouncementModalOpen`).
+    *   On data load, compare the fetched `update_time` with the stored `flvx_announcement_seen_time`. If the fetched time is greater (or if no stored time exists), set `isAnnouncementModalOpen(true)`.
+
+## Error Handling and Edge Cases
+*   If `localStorage` is unavailable or throws an error (e.g., Private Browsing mode restrictions), the modal may show repeatedly. The code should safely catch `localStorage` access errors.
+*   If `update_time` is missing from an old database record, the backend should gracefully fall back to the creation time or a safe default (like 0) to ensure the logic doesn't break.

sagit	7b9b59644e	fix(ui): restore missing UI transition animations (#408 ) - Wrap `Routes` with `AnimatePresence` to enable framer-motion page transition exit animations and fix harsh route changes. - Replace `tw-animate-css` with `tailwindcss-animate` to properly bundle transition classes (like `animate-in`, `animate-accordion-down`) under Tailwind v4. - This restores animation to modals, accordions, and all page navigations. - Fix accessibility warning on table cell span element. Fixes #283	2026-04-03 20:55:43 +08:00
sagit	4e088afb29	feat: show license expiry date when commercial license is activated (#407 ) ## Summary - Extracted the `expiry` attribute from Keygen's `ValidateResponse`. - Updated `licenseActivate` and `validateLicenseJob` to store `license_expiry` in the database. - Read `license_expiry` into the frontend `siteConfig` map. - Updated the description in the commercial license input to dynamically show the expiry date: '已激活商业版授权 (有效期至: YYYY-MM-DD)' or '已激活商业版授权 (永久有效)' if it doesn't expire.	2026-04-03 17:39:07 +08:00

sagit	9412d24c02	feat: show tunnel traffic ratio in forward list (#405 ) ## Summary - Display the tunnel's traffic ratio in the forward (rules) list UI to save administrators an extra click to the tunnels page. - Resolves #forward-show-tunnel-ratio ## Changes - Updated the table row in `forward.tsx` to show the traffic multiplier. - It will only display when the ratio is not `1x` to prevent UI clutter. - The backend `forwardList` API was already returning `trafficRatio` from a `LEFT JOIN tunnel`, so no backend modifications were required.	2026-04-03 16:34:04 +08:00
sagit	ab3ca019d2	fix: prevent idle transaction timeout in postgresql during tunnel update (#404 ) ## Summary - Moved `tx := h.repo.BeginTx()` below `applyFederationRuntime` in `tunnelUpdate` - This prevents the database transaction from remaining idle for an extended period of time while making HTTP network requests to federation nodes, which can trigger the `idle_in_transaction_session_timeout` or cause connection pool exhaustion in PostgreSQL. ## Test Plan - [x] Backend tests passed (`go test ./...`) - [ ] Verify tunnel updates no longer timeout with PostgreSQL	2026-04-03 16:30:35 +08:00
