+# 发现页与资料「出现在发现中」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:** 为登录用户提供 `/discover` 用户名录（仅含自愿曝光且具备公开 slug 的活跃用户）、在 `AppShell` 增加「发现」入口，并在 `/me/profile` 配置发现开关与地址展示；数据经 Drizzle 迁移与受鉴权保护的列表 API 提供。
+
+**Architecture:** 在 SQLite `users` 表增加三个发现相关列；`server/service/discover` 封装分页列表查询与 DTO 映射（头像规则与 `about.get` 一致：`avatarVisibility === "public"` 才返回 URL）；`GET /api/discover/users` 走现有默认 API 鉴权；前端发现页用 `useClientApi` 拉取列表，资料页扩展表单字段与 `PUT /api/me/profile`。
+
+**Tech Stack:** Nuxt 4、Vue 3、Drizzle ORM（SQLite）、better-sqlite3、Zod、Bun test、`normalizePublicListPage`、现有 `R.success` / `defineWrappedResponseHandler` 模式。
+
+**Spec:** `docs/superpowers/specs/2026-04-18-discover-page-design.md`
+

+## File map（将创建或修改）
+
+| 路径 | 职责 |
+| --- | --- |
+| `packages/drizzle-pkg/database/sqlite/schema/auth.ts` | `users` 表新列：`discoverVisible`、`discoverLocation`、`discoverShowLocation` |
+| `packages/drizzle-pkg/migrations/0006_*.sql`（`db:generate` 产出） | SQLite `ALTER TABLE` / 新表迁移片段 |
+| `server/constants/discover-list.ts` | `DISCOVER_LIST_PAGE_SIZE`（建议值 `10`，与 `PUBLIC_LIST_PAGE_SIZE` 相同） |
+| `server/utils/discover-card.ts` | 纯函数：卡片头像 URL、卡片地址文案（可单测） |
+| `server/utils/discover-card.test.ts` | 上述函数单元测试 |

+| `server/api/me/profile.put.ts` | body 类型与 `updateProfile` 传参 |
+| `server/api/me/profile.get.ts` | `profile` JSON 增加 discover 三字段（布尔与字符串，便于表单） |
+| `app/components/AppShell.vue` | 桌面/移动导航「发现」 |
+| `app/pages/discover/index.vue` | 网格列表、分页、空状态、链到 `/@slug` |
+| `app/pages/me/profile/index.vue` | 「发现与展示」分组、保存 body、slug 联动提示 |

+
+### Task 1: 数据库 schema 与迁移
+
+**Files:**
+
+- Modify: `packages/drizzle-pkg/database/sqlite/schema/auth.ts`
+- Create: `packages/drizzle-pkg/migrations/0006_discover.sql`（若 `db:generate` 生成不同文件名，以生成结果为准，并确保 `_journal.json` 与 `meta/*_snapshot.json` 一并更新）
+- Modify: `packages/drizzle-pkg/migrations/meta/_journal.json`（若使用 `drizzle-kit generate` 通常自动更新）
+
+- [ ] **Step 1: 在 `users` 表增加列**
+
+在 `packages/drizzle-pkg/database/sqlite/schema/auth.ts` 的 `users` 定义对象中 **紧跟** `avatarVisibility` 或 `socialLinksJson` 附近追加（保持与现有风格一致，列名 snake_case）：
+
+```ts
+discoverVisible: integer("discover_visible", { mode: "boolean" })
+  .notNull()
+  .default(false),
+discoverLocation: text("discover_location"),
+discoverShowLocation: integer("discover_show_location", { mode: "boolean" })
+  .notNull()
+  .default(false),
+```
+
+若当前仓库的 Drizzle 版本对 `integer(..., { mode: "boolean" })` 报错，可退化为 `integer().notNull().default(0)` 并在应用层用 `=== 1` 判断；**计划以 boolean mode 为首选**。
+
+- [ ] **Step 2: 生成迁移**
+
+在项目根目录执行：
+
+```bash
+bun run db:generate
+```
+
+Expected: `packages/drizzle-pkg/migrations/` 下出现新 SQL，`meta/_journal.json` 增加条目。若生成 SQL 仅含 `ALTER TABLE users ADD ...`，检查默认值与 `NOT NULL` 与 spec 一致。
+
+- [ ] **Step 3: 本地应用迁移**
+
+```bash
+bun run db:migrate
+```
+
+Expected: 命令成功退出；本地 `db.sqlite`（若使用）含新列。
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add packages/drizzle-pkg/database/sqlite/schema/auth.ts packages/drizzle-pkg/migrations packages/drizzle-pkg/migrations/meta
+git commit -m "feat(db): add discover visibility columns on users"
+```
+
+---
+
+### Task 2: 发现卡片 DTO 纯函数与单元测试
+
+**Files:**
+
+- Create: `server/utils/discover-card.ts`
+- Create: `server/utils/discover-card.test.ts`
+
+- [ ] **Step 1: 写失败测试**
+
+创建 `server/utils/discover-card.test.ts`：
+
+```ts
+import { describe, expect, test } from "bun:test";
+import { discoverCardAvatarUrl, discoverCardLocationLine } from "./discover-card";
+
+describe("discoverCardAvatarUrl", () => {
+  test("returns null when visibility is not public", () => {
+    expect(discoverCardAvatarUrl("https://x/a.png", "private")).toBeNull();
+    expect(discoverCardAvatarUrl("https://x/a.png", "unlisted")).toBeNull();
+  });
+
+  test("returns null when avatar empty", () => {
+    expect(discoverCardAvatarUrl(null, "public")).toBeNull();
+    expect(discoverCardAvatarUrl("  ", "public")).toBeNull();
+  });
+
+  test("returns trimmed url when public", () => {
+    expect(discoverCardAvatarUrl(" https://x/a.png ", "public")).toBe("https://x/a.png");
+  });
+});
+
+describe("discoverCardLocationLine", () => {
+  test("returns null when show flag false or text empty", () => {
+    expect(discoverCardLocationLine(true, false, "北京")).toBeNull();
+    expect(discoverCardLocationLine(true, true, "")).toBeNull();
+    expect(discoverCardLocationLine(true, true, "  ")).toBeNull();
+  });
+
+  test("returns trimmed text when allowed", () => {
+    expect(discoverCardLocationLine(true, true, " 上海 ")).toBe("上海");
+  });
+});
+```
+
+- [ ] **Step 2: 运行测试确认失败**
+
+```bash
+bun test server/utils/discover-card.test.ts
+```
+
+Expected: FAIL（模块或函数不存在）。
+
+- [ ] **Step 3: 最小实现**
+
+创建 `server/utils/discover-card.ts`：
+
+```ts
+export function discoverCardAvatarUrl(
+  avatar: string | null | undefined,
+  avatarVisibility: string,
+): string | null {
+  if (avatarVisibility !== "public") {
+    return null;
+  }
+  const t = typeof avatar === "string" ? avatar.trim() : "";
+  return t.length > 0 ? t : null;
+}
+
+export function discoverCardLocationLine(
+  discoverVisible: boolean,
+  discoverShowLocation: boolean,
+  discoverLocation: string | null | undefined,
+): string | null {
+  if (!discoverVisible || !discoverShowLocation) {
+    return null;
+  }
+  const t = typeof discoverLocation === "string" ? discoverLocation.trim() : "";
+  return t.length > 0 ? t : null;
+}
+```
+
+- [ ] **Step 4: 运行测试确认通过**
+
+```bash
+bun test server/utils/discover-card.test.ts
+```
+
+Expected: PASS。
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add server/utils/discover-card.ts server/utils/discover-card.test.ts
+git commit -m "feat(server): add discover card DTO helpers"
+```
+
+---
+
+### Task 3: Discover 列表服务与 API
+
+**Files:**
+
+- Create: `server/constants/discover-list.ts`
+- Create: `server/service/discover/index.ts`
+- Create: `server/api/discover/users.get.ts`
+
+- [ ] **Step 1: 列表常量**
+
+`server/constants/discover-list.ts`：
+
+```ts
+/** 发现页用户列表每页条数（与公开列表一致） */
+export const DISCOVER_LIST_PAGE_SIZE = 10;
+```
+
+- [ ] **Step 2: 服务实现**
+
+`server/service/discover/index.ts`（根据实际 `users` 列类型调整布尔比较；若列为 0/1 integer，用 `eq(users.discoverVisible, true)` 或 `eq(users.discoverVisible, 1)`，以 Drizzle 推断为准）：
+
+```ts
+import { dbGlobal } from "drizzle-pkg/lib/db";
+import { users } from "drizzle-pkg/lib/schema/auth";
+import { and, eq, isNotNull, sql } from "drizzle-orm";
+import { DISCOVER_LIST_PAGE_SIZE } from "#server/constants/discover-list";
+import { normalizePublicListPage } from "#server/utils/public-pagination";
+import { discoverCardAvatarUrl, discoverCardLocationLine } from "#server/utils/discover-card";
+
+const listWhere = and(
+  eq(users.status, "active"),
+  eq(users.discoverVisible, true),
+  isNotNull(users.publicSlug),
+  sql`length(trim(${users.publicSlug})) > 0`,
+);
+
+export type DiscoverListItem = {
+  publicSlug: string;
+  displayName: string;
+  avatar: string | null;
+  location: string | null;
+};
+
+function mapRow(row: typeof users.$inferSelect): DiscoverListItem {
+  const displayName = row.nickname?.trim() || row.username;
+  const discoverVis = Boolean(row.discoverVisible);
+  const showLoc = Boolean(row.discoverShowLocation);
+  return {
+    publicSlug: row.publicSlug as string,
+    displayName,
+    avatar: discoverCardAvatarUrl(row.avatar, row.avatarVisibility),
+    location: discoverCardLocationLine(discoverVis, showLoc, row.discoverLocation),
+  };
+}
+
+export async function listDiscoverUsersPage(pageRaw: unknown) {
+  const page = normalizePublicListPage(pageRaw);
+  const pageSize = DISCOVER_LIST_PAGE_SIZE;
+  const offset = (page - 1) * pageSize;
+
+  const countRows = await dbGlobal
+    .select({ total: sql<number>`count(*)` })
+    .from(users)
+    .where(listWhere);
+  const total = countRows[0]?.total ?? 0;
+
+  const rows = await dbGlobal
+    .select()
+    .from(users)
+    .where(listWhere)
+    .limit(pageSize)
+    .offset(offset);
+
+  return {
+    items: rows.map(mapRow),
+    total,
+    page,
+    pageSize,
+  };
+}
+```
+
+若 `sql\`length(trim(...))\`` 在类型或运行时报错，可改为 `ne(users.publicSlug, "")` 等与 `isNotNull` 组合，确保无空字符串 slug。
+
+- [ ] **Step 3: HTTP 处理器**
+
+`server/api/discover/users.get.ts`：
+
+```ts
+import { listDiscoverUsersPage } from "#server/service/discover";
+
+export default defineWrappedResponseHandler(async (event) => {
+  await event.context.auth.requireUser();
+  const q = getQuery(event);
+  const payload = await listDiscoverUsersPage(q.page);
+  return R.success(payload);
+});
+```
+
+- [ ] **Step 4: 手动验证 API**
+
+启动 `bun run dev`，用已登录会话（浏览器或 cookie）请求：
+
+```bash
+curl -sS -b "你的会话 cookie" "http://localhost:3000/api/discover/users?page=1"
+```
+
+Expected: `200`，JSON 结构含 `items`、`total`、`page`、`pageSize`；未登录时：
+
+```bash
+curl -sS -o /dev/null -w "%{http_code}" "http://localhost:3000/api/discover/users"
+```
+
+Expected: `401`。
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add server/constants/discover-list.ts server/service/discover/index.ts server/api/discover/users.get.ts
+git commit -m "feat(api): add paginated discover users list"
+```
+
+---
+
+### Task 4: 个人资料读写扩展
+
+**Files:**
+
+- Modify: `server/service/profile/index.ts`
+- Modify: `server/api/me/profile.put.ts`
+- Modify: `server/api/me/profile.get.ts`
+
+- [ ] **Step 1: 扩展 `updateProfile`**
+
+在 `server/service/profile/index.ts` 中：
+
+1. 增加 zod（示例，可与文件现有风格合并）：
+
+```ts
+const discoverLocationSchema = z
+  .string()
+  .max(200)
+  .optional()
+  .transform((s) => (s === undefined ? undefined : s.trim() || null));
+```
+
+2. `updateProfile` 的 `patch` 类型增加：
+
+```ts
+discoverVisible?: boolean;
+discoverLocation?: string | null;
+discoverShowLocation?: boolean;
+```
+
+3. 在函数体中处理（注意仅当 `!== undefined` 时写入）：
+
+```ts
+if (patch.discoverVisible !== undefined) {
+  updates.discoverVisible = patch.discoverVisible;
+}
+if (patch.discoverLocation !== undefined) {
+  updates.discoverLocation = discoverLocationSchema.parse(patch.discoverLocation ?? "");
+}
+if (patch.discoverShowLocation !== undefined) {
+  updates.discoverShowLocation = patch.discoverShowLocation;
+}
+```
+
+若 `discoverLocationSchema` 对 `null` 需单独分支，改为：`patch.discoverLocation === null ? null : discoverLocationSchema.parse(...)`。
+
+- [ ] **Step 2: `profile.put` body**
+
+`server/api/me/profile.put.ts` 的 `readBody` 类型增加：
+
+```ts
+discoverVisible?: boolean;
+discoverLocation?: string | null;
+discoverShowLocation?: boolean;
+```
+
+并传入 `updateProfile`。
+
+- [ ] **Step 3: `profile.get` 响应**
+
+`server/api/me/profile.get.ts` 的 `profile` 对象增加：
+
+```ts
+discoverVisible: Boolean(row.discoverVisible),
+discoverLocation: row.discoverLocation ?? null,
+discoverShowLocation: Boolean(row.discoverShowLocation),
+```
+
+（若 row 类型尚未含新列，先完成 Task 1 并确保 TypeScript 从 schema 推断更新。）
+
+- [ ] **Step 4: 手动验证**
+
+登录后 `PUT /api/me/profile` 带 `discoverVisible: true` 等，再 `GET /api/me/profile` 确认回读；再 `GET /api/discover/users` 确认列表仅在 slug 存在时出现该用户。
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add server/service/profile/index.ts server/api/me/profile.put.ts server/api/me/profile.get.ts
+git commit -m "feat(profile): persist discover visibility and location fields"
+```
+
+---
+
+### Task 5: AppShell 导航
+
+**Files:**
+
+- Modify: `app/components/AppShell.vue`
+
+- [ ] **Step 1: 增加 `discoverNav` 常量**
+
+在 `homeNav` 旁：
+
+```ts
+const discoverNav = { label: '发现', to: '/discover', icon: 'i-lucide-compass' } as const
+```
+
+- [ ] **Step 2: 桌面主导航**
+
+在「首页」`UButton` 与「控制台」`UDropdownMenu` 之间插入「发现」`UButton`：`to`、`icon`、`label`、`navActive(discoverNav.to)` 的 class 与首页一致。
+
+- [ ] **Step 3: 移动端菜单**
+
+`mobileMenuItems` 的第一组由 `[homeNav]` 改为 `[homeNav, discoverNav]`（或等价结构），使汉堡菜单可见「发现」。
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add app/components/AppShell.vue
+git commit -m "feat(nav): add Discover link for logged-in users"
+```
+
+---
+
+### Task 6: 发现页 `/discover`
+
+**Files:**
+
+- Create: `app/pages/discover/index.vue`
+
+- [ ] **Step 1: 页面骨架**
+
+- `definePageMeta({ title: '发现' })`（或与项目标题惯例一致）。
+- 使用 `useClientApi` 的 `fetchData` 请求 `/api/discover/users?page=${page}`。
+- 状态：`items`、`total`、`page`、`pageSize`、`loading`、`error`（可选）。
+- 模板：响应式网格（如 `grid gap-4 sm:grid-cols-2 lg:grid-cols-3`），每卡 `NuxtLink` 到 `` `/@${item.publicSlug}` ``，展示 `UAvatar`（`src` 可为空）、`displayName`、`@publicSlug`、可选 `location` 一行。
+- `items.length === 0` 且非 loading：空状态文案（例如「暂时还没有用户出现在发现中」）。
+- 分页：`UPagination` 或「上一页/下一页」，绑定 `page`，`total` 与 `pageSize` 来自 API。
+
+参考现有列表页（如 `app/pages/me/posts/index.vue`）的 loading / toast 模式，保持 UX 一致。
+
+- [ ] **Step 2: 浏览器验证**
+
+登录后打开 `/discover`，确认有数据时卡片可跳转公开主页；未登录访问应被重定向到 `/login?redirect=/discover`。
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add app/pages/discover/index.vue
+git commit -m "feat(pages): add discover directory page"
+```
+
+---
+
+### Task 7: 资料页「发现与展示」
+
+**Files:**
+
+- Modify: `app/pages/me/profile/index.vue`
+
+- [ ] **Step 1: 扩展 `ProfileGet` 与 `state`**
+
+类型与 `reactive` 默认值：
+
+```ts
+discoverVisible: false,
+discoverLocation: '',
+discoverShowLocation: false,
+```
+
+`load()` 中从 `p.discoverVisible` 等赋值（注意 API 返回布尔）。
+
+- [ ] **Step 2: 表单区块**
+
+在「公开主页 slug」字段 **之后**（便于上下文）插入 `UCard` 或 `UFormField` 分组 **「发现与展示」**：
+
+- `USwitch` 或 checkbox：`出现在发现页` → `state.discoverVisible`
+- `UInput`：`地址或地区（展示文案）` → `state.discoverLocation`，可 `maxlength="200"`
+- `USwitch`：`在发现卡片上显示上述地址` → `state.discoverShowLocation`
+- 当 `state.discoverVisible && !state.publicSlug.trim()`：`UAlert` 或说明文字：「需设置公开主页 slug 后才会出现在发现列表中」
+
+- [ ] **Step 3: `save()` body**
+
+在 `fetchData('/api/me/profile', { body: { ... } })` 中增加：
+
+```ts
+discoverVisible: state.discoverVisible,
+discoverLocation: state.discoverLocation.trim() || null,
+discoverShowLocation: state.discoverShowLocation,
+```
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add app/pages/me/profile/index.vue
+git commit -m "feat(profile): discover visibility and location controls"
+```
