 > **如何判断是否需要迁移**：如果你是全新安装，或者你的机器人数据库中 `identity` 字段已经是空的，则**无需任何操作**。完成上述步骤后，按下面对应的系统升级步骤执行即可。
 
+### 从 WebUI 无鉴权版本升级（重要）
+
+本次更新引入了**强制 WebUI 鉴权**。从无鉴权旧版本升级后，**WebUI 必须先创建管理员账号才能使用**。所有 `/api/*` 端点（除少量公共白名单）和 `/ws` 现在都需要登录。
+
+**升级行为**：
+
+- 启动时数据库自动迁移：新增 `users`、`sessions`、`user_audit` 三张表；旧的 `bot_instances`、`play_history` 数据**完全保留**。
+- 第一次打开 WebUI 自动跳转到 `/first-run` 引导创建首位管理员（角色固定为 `admin`）。
+- 之后访问任何页面都会校验登录态，未登录跳转 `/login`。
+
+**会话与 Cookie**：
+
+- 登录态保存 7 天，每次请求滚动续期（活跃用户不会被踢出）。
+- 同一账号最多保持 10 个并发会话（超过自动剔除最旧的）。
+- Cookie 设置为 `HttpOnly; SameSite=Lax`，HTTPS 部署需配合 `trustProxy: true`（详见 [反向代理部署注意事项](#反向代理部署注意事项)）。
+
+**多用户与角色**：
+
+- 角色 `admin`：完整权限（用户管理、审计、机器人、音乐平台、播放控制）。
+- 角色 `member`：除"用户管理"和"操作审计"外的所有功能（适合给团队成员开通播放权）。
+- 在 **设置 → 用户管理**（仅管理员）中添加 / 删除 / 重置密码 / 切换角色。
+- 至少保留一个管理员：系统会阻止删除或降级最后一位管理员。
+
+**如何重置忘记的管理员密码**：
+
+如果你忘记了管理员密码，可以直接编辑 SQLite 数据库 `data/tsmusicbot.db`：
+
+```bash
+# 方案 1：清空所有用户，重新进入 first-run 流程
+sqlite3 data/tsmusicbot.db "DELETE FROM users; DELETE FROM sessions;"
+# 然后重启机器人，浏览器再次访问会自动进入 /first-run
+
+# 方案 2：把指定用户重置为已知密码（密码 'changeme-now' 的 bcrypt 哈希示例如下）
+# 先用 node 生成哈希：
+node -e "console.log(require('bcryptjs').hashSync('changeme-now', 12))"
+# 把输出贴到 SQL 里：
+sqlite3 data/tsmusicbot.db "UPDATE users SET passwordHash='<paste-hash-here>' WHERE username='你的用户名';"
+```
+
+**反向代理用户特别注意**：如果通过 nginx / Caddy / Cloudflare 暴露 WebUI，**必须**在 `config.json` 中设置 `"trustProxy": true`，否则 Cookie 不会带 `Secure` 标志，且登录限流会把所有用户合并到同一个桶。详见下方 [反向代理部署注意事项](#反向代理部署注意事项)。
+
+**旧版 `config.adminPassword` / `adminGroups`**：这两个配置项在旧版本中预留但从未实际启用（TS-side admin 命令权限的占位字段）。保留以避免破坏旧 `config.json`，但不再影响任何行为。可以放心忽略。

 **Q：如何更新到新版本？**
 A：`git pull` 拉取最新代码，然后 `npm install && npm run build && npm start` 重新构建启动。Docker 用户执行 `docker-compose up -d --build`。
 
+**Q：忘记管理员密码怎么办？**
+A：直接操作 SQLite 数据库。最简单的办法是清空 `users` 表然后重新进入 first-run 流程：`sqlite3 data/tsmusicbot.db "DELETE FROM users; DELETE FROM sessions;"`，重启后浏览器会自动跳转 `/first-run` 让你重新创建管理员。详细方法见 [从 WebUI 无鉴权版本升级](#从-webui-无鉴权版本升级重要)。
+
+**Q：成员（member）能做什么？不能做什么？**
+A：成员默认可以：管理机器人（启动/停止/创建/编辑）、控制播放（搜索/播放/队列）、登录音乐平台账号、修改自己的密码。成员**始终不能**：管理其他用户、查看操作审计日志、降级或删除管理员。此外管理员可在 **设置 → 用户管理** 为每个成员单独**收紧权限**：勾选允许的能力（播放控制 / 队列 / 机器人管理 / 平台登录 / 音质）以及可操作的机器人白名单——未授权的能力会返回 403，未授权的机器人对该成员不可见也不可控。管理员不受任何限制。
+
+**Q：收藏的歌单存在哪里？其他用户能看到吗？**
+A：收藏按用户存储在本地 SQLite 数据库（`favorite_playlists` 表），仅本人可见，登录后跨设备同步。在首页、搜索结果或歌单页点击收藏图标即可增删。
+
+**Q：什么是"专属链接"？怎么用？**
+A：通过 `/bot/<机器人ID>` 打开 WebUI 会把界面锁定到该机器人（顶部显示"专属模式"，刷新后保持），适合把单台机器人的控制页分享给特定用户。点击"退出"可返回多机器人视图。注意：专属链接只是 UI 层的锁定，真正的访问控制由成员权限（机器人白名单）在后端强制。
+
+**Q：机器人播放时突然自动暂停了？**
+A：这是"频道无人时自动暂停"功能：当机器人所在频道没有其他人时会自动暂停，有人加入后自动恢复，避免空播。该功能**默认关闭**，仅在你于 **设置 → 行为设置** 开启后生效；如需停用，在同一页面关闭即可。（占用检测依赖 TeamSpeak 的 `clientlist` 命令，部分服务器在频道有其他人时可能查询失败——此时机器人会按"占用情况未知"处理，不会误暂停。）
+
+**Q：如何把某个用户从成员升级为管理员？**
+A：管理员登录后进入 **设置 → 用户管理**，点击对应用户的"提升管理员"按钮即可。降级同理（"降为成员"按钮）。系统会阻止降级最后一位管理员。
+
+**Q：登录之后多久会自动退出？**
+A：登录态有效期 7 天，活跃使用会滚动续期（每次受保护请求都会刷新过期时间）。同一账号最多保持 10 个并发会话（多设备登录时超过的会自动剔除最旧的会话）。
+
+**Q：部署到公网后如何防止暴力登录？**
+A：本项目内置 `/login` 限流（每 IP 每分钟 5 次），但生产部署建议同时在反向代理（nginx `limit_req` / Caddy 等）层加一层限流，并启用 HTTPS。反向代理部署务必设置 `"trustProxy": true`（详见 [反向代理部署注意事项](#反向代理部署注意事项)）。

+# Account Permissions 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:** Let an admin grant each member account a set of capabilities and a list of bots they may control, enforced on the backend.
+
+**Architecture:** Capability tokens + per-member bot allow-list stored in two new SQLite tables, loaded onto `req.user` per request (live, no re-login), enforced by `requirePermission` / `requireBotAccess` middleware mirroring the existing `requireAdmin`. Admin stays a super-user. Existing members are backfilled to full access on upgrade; new members get a basic tier. The Vue UI hides what a member can't do and gives admins a permission editor.
+
+**Tech Stack:** Node ESM + TypeScript, Express, better-sqlite3, Vitest + supertest, Vue 3 + Pinia.
+
+**Spec:** `docs/superpowers/specs/2026-05-30-account-permissions-design.md`
+
+**Conventions:** All file paths are repo-relative. Tests run with `npx vitest run <path>`. Backend is TDD (test first, watch fail, implement, watch pass, commit). Commit after each task.
+
+---
+
+## File Structure
+
+**Create:**
+- `src/data/permissions.ts` — capability constants + `PermissionStore` (tables accessed here)
+- `src/data/permissions.test.ts` — store + constants tests
+- `src/web/middleware/requirePermission.ts` — `requirePermission(cap)` + `requireBotAccess(param)`
+- `src/web/middleware/requirePermission.test.ts` — middleware tests
+
+**Modify:**
+- `src/data/database.ts` — `initTables`: add the two tables + index; migration backfill of existing members
+- `src/data/audit.ts` — add `"user.permissions_changed"` to `AuditAction`
+- `src/web/middleware/requireAuth.ts` — widen `req.user`; load capabilities + bot access
+- `src/web/auth/validateSession.ts` — (no change; just confirm) — actually unchanged
+- `src/web/api/session.ts` — `/me` returns capabilities + bots; inline auth attaches them
+- `src/web/server.ts` — construct `PermissionStore`, pass into routers/middleware
+- `src/web/api/player.ts` — `requireBotAccess` on `/:botId`; per-route `requirePermission`
+- `src/web/api/bot.ts` — `requirePermission("bot.manage")` + `requireBotAccess("id")`
+- `src/web/api/auth.ts` — `requirePermission("platform.auth")`
+- `src/web/api/music.ts` — `requirePermission("quality")` on the quality POST; filter `GET /api/bot`? no — bot list is in bot.ts
+- `src/web/api/bot.ts` — filter `GET /` to allowed bots for members

+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `npx vitest run src/data/permissions.test.ts`

+
+- [ ] **Step 3: Create `src/data/permissions.ts`**
+
+```typescript

+  "player.control",
+  "player.queue",
+  "bot.manage",

+}
+```
+
+- [ ] **Step 4: Add tables in `src/data/database.ts` initTables**
+
+Find `initTables` (creates users/sessions/user_audit). Add, after the `user_audit` CREATE:
+
+```typescript
+  db.exec(`
+    CREATE TABLE IF NOT EXISTS user_permissions (
+      userId     TEXT NOT NULL,
+      permission TEXT NOT NULL,
+      PRIMARY KEY (userId, permission),
+      FOREIGN KEY (userId) REFERENCES users(id) ON DELETE CASCADE
+    );
+    CREATE TABLE IF NOT EXISTS user_bot_access (
+      userId TEXT NOT NULL,
+      botId  TEXT NOT NULL,
+      PRIMARY KEY (userId, botId),
+      FOREIGN KEY (userId) REFERENCES users(id) ON DELETE CASCADE
+    );
+    CREATE INDEX IF NOT EXISTS idx_user_bot_access_userId ON user_bot_access(userId);
+  `);
+```
+
+(If `initTables` uses individual `db.exec` calls, match that style. The `BotDatabase` type already exposes `.db` and `.close()` — confirm by reading the file; the test uses `db.db` and `db.close()`.)
+
+- [ ] **Step 5: Run tests to verify they pass**
+
+Run: `npx vitest run src/data/permissions.test.ts`
+Expected: PASS (7 tests).
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/data/permissions.ts src/data/permissions.test.ts src/data/database.ts
+git commit -m "feat(perm): permission store + capability tokens + tables"

+## Task 2: requirePermission + requireBotAccess middleware
+
+**Files:**
+- Create: `src/web/middleware/requirePermission.ts`
+- Create: `src/web/middleware/requirePermission.test.ts`
+- Modify: `src/web/middleware/requireAuth.ts` (widen `req.user`)
+
+- [ ] **Step 1: Widen the `req.user` augmentation in `src/web/middleware/requireAuth.ts`**
+
+Change the `declare module` block so `req.user` carries capabilities + bot access:
+
+```typescript
+declare module "express-serve-static-core" {
+  interface Request {
+    user?: {
+      id: string;
+      username: string;
+      role: "admin" | "member";
+      capabilities: Set<string>;
+      bots: "all" | Set<string>;
+    };
+  }
+}
+```
+
+(The loading of these fields is done in Task 4 — for now this only widens the type. Existing assignments to `req.user` will fail to typecheck until Task 4; that is expected and Task 4 fixes them. If you need the build green between tasks, do Task 2 + Task 4 back-to-back before running `tsc`.)
+
+- [ ] **Step 2: Write the failing middleware test**

+  });
+});
+```
+
+- [ ] **Step 2: Run to verify fail**
+
+Run: `npx vitest run src/data/permissions.test.ts`
+Expected: FAIL — `resolvePermissionContext` not exported.

+- [ ] **Step 3: Add to `src/data/permissions.ts`**

+## Task 4: Load permissions onto req.user (requireAuth + session inline + /me)
+
+**Files:**
+- Modify: `src/web/middleware/requireAuth.ts`
+- Modify: `src/web/api/session.ts`
+- Modify: `src/web/server.ts`
+
+- [ ] **Step 1: Thread `PermissionStore` into `createRequireAuth`**
+
+`src/web/middleware/requireAuth.ts` — change the factory signature and set the new fields:
+
+```typescript
+import { resolvePermissionContext, type PermissionStore } from "../../data/permissions.js";
+
+export function createRequireAuth(sessions: SessionStore, permissions: PermissionStore): RequestHandler {
+  return function requireAuth(req, res, next) {
+    const result = validateSessionFromHeaders(req.headers.cookie, sessions);
+    if (!result) {
+      res.clearCookie(SESSION_COOKIE_NAME, { path: "/" });
+      res.status(401).json({ error: "unauthenticated" });
+      return;
+    }
+    const ctx = resolvePermissionContext(result.role, result.userId, permissions);
+    req.user = {
+      id: result.userId, username: result.username, role: result.role,
+      capabilities: ctx.capabilities, bots: ctx.bots,
+    };
+    const token = extractSessionToken(req.headers.cookie);
+    if (token) {
+      res.cookie(SESSION_COOKIE_NAME, token, {
+        httpOnly: true, sameSite: "lax", secure: req.secure, path: "/", maxAge: SESSION_TTL_MS,
+      });
+    }
+    next();
+  };
+}
+```
+
+- [ ] **Step 2: Update `src/web/server.ts`**
+
+Construct the store next to the others and pass it in:
+
+```typescript
+import { createPermissionStore } from "../data/permissions.js";
+// ...
+const permissions = createPermissionStore(options.database.db);
+// ...
+const requireAuth = createRequireAuth(sessions, permissions);
+```
+
+Keep `permissions` in scope — it's passed to routers in Tasks 5–7.
+
+- [ ] **Step 3: Update session inline auth + `/me` in `src/web/api/session.ts`**
+
+`createSessionRouter` must accept `permissions` and (a) attach capabilities in `requireAuthInline`, (b) include them in `/me`. Pass `permissions` from `server.ts` into `createSessionRouter(users, sessions, audit, logger, permissions)`. In the `/me` handler, return:
+
+```typescript
+const ctx = resolvePermissionContext(validation.role, validation.userId, permissions);
+res.json({
+  id: validation.userId, username: validation.username, role: validation.role,
+  capabilities: [...ctx.capabilities],
+  bots: ctx.bots === "all" ? "all" : [...ctx.bots],
+});
+```
+
+(Match the existing `/me` shape; just add `capabilities` + `bots`. Read the file to find the exact response object.)
+
+- [ ] **Step 4: Verify build + existing tests**
+
+Run: `npx tsc --noEmit`
+Expected: exit 0 (the widened `req.user` is now populated everywhere it's read).
+
+Run: `npx vitest run src/web`
+Expected: PASS (existing auth/session/csrf tests still green; if a test constructs `createRequireAuth(sessions)` it must be updated to pass a `createPermissionStore(db)`).
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/web/middleware/requireAuth.ts src/web/server.ts src/web/api/session.ts
+git commit -m "feat(perm): load capabilities + bot access onto req.user; expose via /me"

+## Task 5: Enforce capabilities on the action routes
+
+**Files:**
+- Modify: `src/web/api/player.ts`, `src/web/api/bot.ts`, `src/web/api/auth.ts`, `src/web/api/music.ts`
+- Modify: `src/web/api/player.test.ts` (or create `src/web/api/permissions-enforcement.test.ts`)
+
+- [ ] **Step 1: Write a failing integration test** at `src/web/api/permissions-enforcement.test.ts` that builds the real app (or the relevant router) with a stubbed `req.user` and asserts:
+  - member without `player.control` → `POST /api/player/:botId/pause` → 403
+  - member with `player.control` + bot in allow-list → 200 (bot resolves)
+  - member with `player.control` but bot NOT in allow-list → 403
+  - member without `player.queue` → `POST /api/player/:botId/clear` → 403
+  - member without `bot.manage` → `POST /api/bot` → 403
+  - member without `platform.auth` → `POST /api/auth/cookie` → 403
+  - member without `quality` → `POST /api/music/quality` → 403
+  - admin → all 200/allowed
+
+  Use the same `appWith(user)` injection pattern as Task 2 (insert a middleware that sets `req.user` before the router) and a fake `BotManager`/providers so routes resolve. Model it on the existing `src/web/api/*.test.ts` setup (read one first for the harness).
+
+- [ ] **Step 2: Run to verify fail** — `npx vitest run src/web/api/permissions-enforcement.test.ts` → FAIL (routes currently allow everyone).
+
+- [ ] **Step 3: Apply gates.**
+
+`src/web/api/player.ts` — the shared `/:botId` middleware already resolves the bot. Add bot-access there, and add per-action capability guards. Define the queue-capability routes vs control routes:
+
+```typescript
+import { requirePermission, requireBotAccess } from "../middleware/requirePermission.js";
+
+// after the existing router.use("/:botId", resolveBot):
+router.use("/:botId", requireBotAccess("botId"));
+
+const control = requirePermission("player.control");
+const queue = requirePermission("player.queue");
+// control: play, pause, resume, next, prev, stop, seek, volume, mode, play-song, play-at, play-by-id, play-playlist, play-album, play-next-song
+// queue:   add, add-song, add-by-id, clear, playlist, /queue/:index (DELETE)
+// Apply per route, e.g.:
+router.post("/:botId/pause", control, async (req, res) => { /* existing */ });
+router.post("/:botId/add", queue, async (req, res) => { /* existing */ });
+router.delete("/:botId/queue/:index", queue, async (req, res) => { /* existing */ });
+```
+
+(Insert the `control`/`queue` middleware as the 2nd arg of each existing `router.post/delete`. Do not change handler bodies. `PUT /:botId/profile` → `requirePermission("bot.manage")`.)
+
+`src/web/api/bot.ts` — gate management + per-bot:
+
+```typescript
+const manage = requirePermission("bot.manage");
+router.post("/", manage, ...);                 // create (no botId)
+router.put("/:id", manage, requireBotAccess("id"), ...);
+router.delete("/:id", manage, requireBotAccess("id"), ...);
+router.post("/:id/start", manage, requireBotAccess("id"), ...);
+router.post("/:id/stop", manage, requireBotAccess("id"), ...);
+router.put("/:id/avatar", manage, requireBotAccess("id"), ...);
+router.delete("/:id/avatar", manage, requireBotAccess("id"), ...);
+router.post("/settings", manage, ...);         // global idle timeout
+```
+
+`src/web/api/auth.ts` — gate every mutating route with `requirePermission("platform.auth")`:
+`POST /qrcode`, `POST /sms/send`, `POST /sms/verify`, `POST /cookie`. (Leave `GET /status`, `GET /qrcode/status` open — read-only.)
+
+`src/web/api/music.ts` — gate the one mutating route:
+`router.post("/quality", requirePermission("quality"), ...)`.
+
+- [ ] **Step 4: Run to verify pass** — `npx vitest run src/web/api/permissions-enforcement.test.ts` → PASS. Then `npx vitest run src/web` → all green.
+
+- [ ] **Step 5: Commit**

+- Modify: `src/web/api/bot.ts` (`GET /`)
+- Modify: `src/bot/manager.ts` (`removeBot` → `permissions.pruneBot`)
+- Modify: test from Task 5
+
+- [ ] **Step 1: Add failing test** — member with `bots: ["b1"]` calling `GET /api/bot` sees only `b1`; admin sees all.
+
+- [ ] **Step 2: Run → fail.**
+
+- [ ] **Step 3: Implement.** In `GET /` of `bot.ts`:
+
+```typescript
+const all = getAllBots().map((b) => b.getStatus());
+const u = req.user!;
+const bots = u.role === "admin" || u.bots === "all"
+  ? all
+  : all.filter((b) => (u.bots as Set<string>).has(b.id));
+res.json({ bots });
+```
+
+In `src/bot/manager.ts`, give `BotManager` access to the `PermissionStore` (constructor param) and call `this.permissions.pruneBot(id)` inside `removeBot(id)` after deletion, so deleted bots drop out of allow-lists. Thread `permissions` from `index.ts`/`server.ts` into `BotManager`.

+
+## Task 7: Management API (GET/PUT permissions) + audit
+
+**Files:**
+- Modify: `src/data/audit.ts` (add action)
+- Modify: `src/web/api/users.ts` (+ permissions endpoints; new-member default)
+- Modify: `src/web/server.ts` (pass `permissions` into `createUsersRouter`)
+- Create/extend: `src/web/api/users.test.ts`
+
+- [ ] **Step 1: Add `"user.permissions_changed"`** to the `AuditAction` union in `src/data/audit.ts`.
+
+- [ ] **Step 2: Write failing tests** for the users router (admin-only):
+  - `GET /api/users/:id/permissions` → `{ capabilities: [], bots: [] }` for a fresh member.
+  - `PUT /api/users/:id/permissions` with `{capabilities:["player.control"], bots:"all"}` → 200; subsequent GET reflects it; an audit row `user.permissions_changed` exists.
+  - `PUT` with an unknown capability token → it is dropped (not stored).
+  - New member created via `POST /api/users` → GET permissions returns basic tier (`["player.control","player.queue"]`, bots `"all"`).
+
+- [ ] **Step 3: Run → fail.**
+
+- [ ] **Step 4: Implement** in `src/web/api/users.ts` (router already admin-gated at mount). Accept `permissions: PermissionStore` param. Add:
+
+```typescript
+import { CAPABILITIES, isCapability, BASIC_TIER_CAPABILITIES } from "../../data/permissions.js";
+
+router.get("/:id/permissions", (req, res) => {
+  const user = users.findById(req.params.id);
+  if (!user) { res.status(404).json({ error: "not_found" }); return; }
+  res.json({ capabilities: permissions.getCapabilities(user.id), bots: permissions.getBotAccess(user.id) });
+});
+
+router.put("/:id/permissions", (req, res) => {
+  const user = users.findById(req.params.id);
+  if (!user) { res.status(404).json({ error: "not_found" }); return; }
+  const body = req.body ?? {};
+  const caps = Array.isArray(body.capabilities) ? body.capabilities.filter(isCapability) : [];
+  const bots = body.bots === "all" ? "all" : (Array.isArray(body.bots) ? body.bots.map(String) : []);
+  permissions.setPermissions(user.id, { capabilities: caps, bots });
+  audit.record({
+    actorId: req.user!.id, actorUsername: req.user!.username,
+    targetUserId: user.id, targetUsername: user.username,
+    action: "user.permissions_changed",
+  });
+  res.json({ success: true });
+});
+```
+
+In the existing `POST /api/users` handler, after creating a member, seed the basic tier:
+
+```typescript
+if (created.role === "member") {
+  permissions.setPermissions(created.id, { capabilities: BASIC_TIER_CAPABILITIES, bots: "all" });
+}
+```
+
+- [ ] **Step 5: Run → pass; `npx vitest run src/web` green.**
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/data/audit.ts src/web/api/users.ts src/web/server.ts src/web/api/users.test.ts
+git commit -m "feat(perm): admin permissions API + audit + new-member basic tier"
+```
+
+---
+
+## Task 8: One-time migration backfill (existing members → full)
+
+**Files:**
+- Modify: `src/data/database.ts` (`migrateSchema` or a dedicated backfill)
+- Create: `src/data/permissions-migration.test.ts`
+
+- [ ] **Step 1: Write failing test** — given a fresh db with an existing `member` user and NO permission rows, after `createDatabase()` runs the backfill, that member has all 5 capabilities + `bots.all`; an `admin` user gets nothing (bypasses). Backfill is idempotent (running twice does not duplicate / does not re-grant a member who was later restricted to empty).
+
+  Idempotency approach: store a one-shot marker. Use a `meta` row or check: only backfill members who currently have ZERO permission rows AND only on first introduction. Simplest robust marker: a row in a tiny `schema_meta(key TEXT PK, value TEXT)` table, key `perm_backfill_done`. If present, skip.
+
+- [ ] **Step 2: Run → fail.**
+
+- [ ] **Step 3: Implement** a `backfillMemberPermissions(db)` run once inside `createDatabase` after `initTables`:
+
+```typescript
+db.exec(`CREATE TABLE IF NOT EXISTS schema_meta (key TEXT PRIMARY KEY, value TEXT)`);
+const done = db.prepare("SELECT value FROM schema_meta WHERE key = 'perm_backfill_done'").get();
+if (!done) {
+  const members = db.prepare("SELECT id FROM users WHERE role = 'member'").all() as { id: string }[];
+  const insCap = db.prepare("INSERT OR IGNORE INTO user_permissions (userId, permission) VALUES (?, ?)");
+  const tx = db.transaction(() => {
+    for (const m of members) {
+      for (const c of ["player.control","player.queue","bot.manage","platform.auth","quality","bots.all"]) {
+        insCap.run(m.id, c);
+      }
+    }
+    db.prepare("INSERT INTO schema_meta (key, value) VALUES ('perm_backfill_done', ?)").run(String(Date.now()));
+  });
+  tx();
+}
+```
+
+- [ ] **Step 4: Run → pass.**
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/data/database.ts src/data/permissions-migration.test.ts
+git commit -m "feat(perm): one-time backfill of existing members to full access"
+```
+
+---
+
+## Task 9: Frontend — session capabilities + helpers
+
+**Files:**
+- Modify: `web/src/composables/useSession.ts`
+
+- [ ] **Step 1:** Extend the `User` type with `capabilities: string[]` and `bots: 'all' | string[]`; populate from `/api/session/me`, `/login`, `/setup` responses (the backend now returns them).
+- [ ] **Step 2:** Add computed helpers:
+
+```typescript
+function can(cap: string): boolean {
+  const u = currentUser.value;
+  return !!u && (u.role === 'admin' || (u.capabilities ?? []).includes(cap));
+}
+function canControlBot(botId: string): boolean {
+  const u = currentUser.value;
+  if (!u) return false;
+  if (u.role === 'admin' || u.bots === 'all') return true;
+  return Array.isArray(u.bots) && u.bots.includes(botId);
+}
+```
+
+Export `can` and `canControlBot` from the composable.
+
+- [ ] **Step 3:** Manual check: log in as admin → `can('quality')` true; (after backend done) a restricted member → false. Build: `cd web && npx vue-tsc --noEmit`.
+- [ ] **Step 4: Commit** `git add web/src/composables/useSession.ts && git commit -m "feat(perm): frontend session capabilities + can()/canControlBot()"`
+
+---
+
+## Task 10: Frontend — gate UI by capability + filter bots
+
+**Files:**
+- Modify: `web/src/components/Navbar.vue`, `web/src/components/Player.vue`, `web/src/views/Settings.vue`, `web/src/stores/player.ts`
+
+- [ ] **Step 1:** Navbar bot selector: render only controllable bots — `v-for="bot in store.bots"` becomes a filtered computed `controllableBots = store.bots.filter(b => session.canControlBot(b.id))`. (The backend already filters `GET /api/bot`, so this is belt-and-suspenders + correctness if both lists diverge.) Ensure `store.activeBot` fallback never lands on a bot the user can't control.
+- [ ] **Step 2:** Player.vue: wrap control buttons with `v-if="session.can('player.control')"` and queue actions with `v-if="session.can('player.queue')"`.
+- [ ] **Step 3:** Settings.vue: wrap the platform login cards with `v-if="session.can('platform.auth')"`, the audio-quality control with `v-if="session.can('quality')"`, and bot create/edit/delete with `v-if="session.can('bot.manage')"`.
+- [ ] **Step 4:** Manual verification (see Verification section). Build: `cd web && npx vue-tsc --noEmit`.
+- [ ] **Step 5: Commit** `git add web/src/components/Navbar.vue web/src/components/Player.vue web/src/views/Settings.vue web/src/stores/player.ts && git commit -m "feat(perm): hide UI a member lacks capability for"`
+
+---
+
+## Task 11: Frontend — admin permission editor
+
+**Files:**
+- Modify: `web/src/views/Settings.vue` (User Management section)
+
+- [ ] **Step 1:** In each member row of the admin User-Management list, add a "权限" button opening an editor (inline panel or dialog) with: 5 capability checkboxes (labels: 播放控制 / 队列管理 / 机器人管理 / 平台登录凭据 / 音质设置), and a bot allow-list — an "全部机器人" toggle plus, when off, a checkbox per bot from `store.bots`.
+- [ ] **Step 2:** On open, `GET /api/users/:id/permissions`; on save, `PUT /api/users/:id/permissions` with `{capabilities, bots}` then re-fetch. Admin rows show "全部权限(管理员)" and no editor.
+- [ ] **Step 3:** Manual verification. Build: `cd web && npx vue-tsc --noEmit`.
+- [ ] **Step 4: Commit** `git add web/src/views/Settings.vue && git commit -m "feat(perm): admin permission editor in user management"`
+
+---
+
+## Final verification
+
+- [ ] `npx tsc --noEmit` → exit 0
+- [ ] `npx vitest run src/` → all green (clean-checkout-equivalent; ignore stale `dist/` twins — see note)
+- [ ] `cd web && npx vue-tsc --noEmit` → exit 0
+- [ ] `npm run build` → succeeds
+- [ ] Manual (run the bot, log in): admin sees everything; create a member, restrict to `player.control` on one bot → member sees only that bot, can play/pause but cannot add to queue, cannot open platform login / quality / bot management; backend returns 403 on a forged request to a disallowed action (verify with curl + the member's session cookie).
+
+> **Note (pre-existing):** `tsconfig.json` compiles `*.test.ts` into `dist/`, and vitest also runs the `dist/` twins after a build — so `npx vitest run` (no path) double-runs and can fail on stale artifacts. Scope verification to `npx vitest run src/`. (A separate cleanup PR could add `exclude: ['**/dist/**']` to a vitest config.)

+# Auto-pause on Empty Channel — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: superpowers:subagent-driven-development. Steps use checkbox (`- [ ]`) syntax.
+
+**Goal:** Auto-pause playback when the bot's channel empties (no disconnect) and auto-resume when someone returns — only resuming tracks we auto-paused — gated by the existing global `autoPauseOnEmpty` flag.
+
+**Architecture:** A pure decision function decides pause/resume from (player state, autoPaused, flag, userCount). `BotInstance` owns an `autoPaused` flag and a `checkChannelOccupancy()` that the existing 30s idle poll AND new TS enter/leave/move events both call. The toggle is wired into `/api/bot/settings` + the Settings UI.
+
+**Tech:** Node ESM + TS, Vitest, Express, Vue 3.
+
+**Spec:** `docs/superpowers/specs/2026-05-30-autopause-empty-channel-design.md`
+
+---
+
+## Task 1: Pure occupancy-decision function
+
+**Files:** Create `src/bot/auto-pause.ts`, `src/bot/auto-pause.test.ts`.
+
+- [ ] **Step 1 — failing test** `src/bot/auto-pause.test.ts`:
+
+```typescript
+import { describe, it, expect } from "vitest";
+import { decideOccupancyAction } from "./auto-pause.js";
+
+describe("decideOccupancyAction", () => {
+  // (playerState, autoPaused, enabled, userCount) => "pause" | "resume" | "none"
+  it("pauses when empty while playing and enabled", () => {
+    expect(decideOccupancyAction("playing", false, true, 0)).toBe("pause");
+  });
+  it("does not pause when the feature is disabled", () => {
+    expect(decideOccupancyAction("playing", false, false, 0)).toBe("none");
+  });
+  it("does not pause when idle (nothing playing)", () => {
+    expect(decideOccupancyAction("idle", false, true, 0)).toBe("none");
+  });
+  it("does not pause when already paused", () => {
+    expect(decideOccupancyAction("paused", false, true, 0)).toBe("none");
+  });
+  it("resumes when re-populated and we auto-paused", () => {
+    expect(decideOccupancyAction("paused", true, true, 2)).toBe("resume");
+  });
+  it("does NOT resume a user-paused track on re-population", () => {
+    expect(decideOccupancyAction("paused", false, true, 2)).toBe("none");
+  });
+  it("does nothing when re-populated and already playing", () => {
+    expect(decideOccupancyAction("playing", false, true, 2)).toBe("none");
+  });
+  it("resume is independent of the enabled flag (we already auto-paused)", () => {
+    expect(decideOccupancyAction("paused", true, false, 1)).toBe("resume");
+  });
+});
+```
+
+- [ ] **Step 2 — run, expect fail:** `npx vitest run src/bot/auto-pause.test.ts` → module missing.
+
+- [ ] **Step 3 — implement** `src/bot/auto-pause.ts`:
+
+```typescript
+export type PlayerStateName = "idle" | "playing" | "paused";
+export type OccupancyAction = "pause" | "resume" | "none";
+
+/**
+ * Decide what auto-pause should do given the channel occupancy.
+ * - empty (userCount <= 0): pause iff enabled and currently playing.
+ * - re-populated (userCount > 0): resume iff we previously auto-paused and are still paused.
+ * `autoPaused` distinguishes our auto-pause from a user pause, so user pauses are never resumed.
+ */
+export function decideOccupancyAction(
+  playerState: PlayerStateName,
+  autoPaused: boolean,
+  enabled: boolean,
+  userCount: number,
+): OccupancyAction {
+  const empty = userCount <= 0;
+  if (empty) {
+    if (enabled && playerState === "playing") return "pause";
+    return "none";
+  }
+  if (autoPaused && playerState === "paused") return "resume";
+  return "none";
+}
+```
+
+- [ ] **Step 4 — run, expect pass:** `npx vitest run src/bot/auto-pause.test.ts` → 8 pass.
+- [ ] **Step 5 — commit:** `git add src/bot/auto-pause.ts src/bot/auto-pause.test.ts && git commit -m "feat(autopause): pure occupancy-decision function"`
+
+---
+
+## Task 2: Wire decision into BotInstance (autoPaused flag + checkChannelOccupancy)
+
+**Files:** Modify `src/bot/instance.ts`.
+
+Context: `_startIdlePoller` (~lines 190-206) polls every 30s, computes `userCount = (await getClientsInChannel()).length - 1`, and calls `_scheduleIdleCheck()` (empty) / `_cancelIdleTimer()` (occupied). `cmdPause`/`cmdResume` (~484-494), `cmdStop` (~496-505), and the playback start (`cmdPlay`/resolveAndPlay) wrap `player`. There's an unused `channelUserCount` field (~line 68). The instance has `this.config` (BotConfig) and `this.player`.
+
+- [ ] **Step 1 — add state + helper.** Add a private field `private autoPaused = false;`. Create a method that centralizes occupancy handling and is called with a freshly-computed userCount:
+
+```typescript
+import { decideOccupancyAction } from "./auto-pause.js";
+
+private handleOccupancy(userCount: number): void {
+  // idle-disconnect (unchanged behavior)
+  if (userCount <= 0) this._scheduleIdleCheck();
+  else this._cancelIdleTimer();
+
+  // auto-pause
+  const action = decideOccupancyAction(
+    this.player.getState() as "idle" | "playing" | "paused",
+    this.autoPaused,
+    this.config.autoPauseOnEmpty,
+    userCount,
+  );
+  if (action === "pause") {
+    this.player.pause();
+    this.autoPaused = true;
+    this.emit("stateChange");
+  } else if (action === "resume") {
+    this.player.resume();
+    this.autoPaused = false;
+    this.emit("stateChange");
+  }
+}
+```
+
+- [ ] **Step 2 — route the idle poller through it.** In `_startIdlePoller`, replace the inline `userCount`→schedule/cancel logic with: compute `userCount` then `this.handleOccupancy(userCount)`. (Keep the 30s interval + the same getClientsInChannel call + error handling.) Remove the now-redundant inline schedule/cancel branch (it lives in `handleOccupancy`).
+
+- [ ] **Step 3 — clear autoPaused on user actions + lifecycle.** In `cmdPause`, `cmdResume`, `cmdStop`, and the play-start path (`cmdPlay`/wherever playback (re)starts), set `this.autoPaused = false`. In the `disconnected` handler and on (re)connect, set `this.autoPaused = false`. (These ensure a user pause is never auto-resumed and the flag resets across connections.)
+
+- [ ] **Step 4 — `updateAutoPause`.** Add (mirrors `updateIdleTimeout`):
+
+```typescript
+updateAutoPause(enabled: boolean): void {
+  this.config.autoPauseOnEmpty = enabled;
+  // if turning off, leave current playback as-is; if a track was auto-paused, optionally resume:
+  if (!enabled && this.autoPaused && this.player.getState() === "paused") {
+    this.player.resume();
+    this.autoPaused = false;
+    this.emit("stateChange");
+  }
+}
+```
+
+- [ ] **Step 5 — verify:** `npx tsc --noEmit` → exit 0. `npx vitest run src/bot src/audio` → pass (existing tests unaffected).
+- [ ] **Step 6 — commit:** `git add src/bot/instance.ts && git commit -m "feat(autopause): drive pause/resume from channel occupancy in BotInstance"`
+
+---
+
+## Task 3: Re-emit TS member events for instant reaction
+
+**Files:** Modify `src/ts-protocol/client.ts`, `src/bot/instance.ts`.
+
+Context: `client.ts` forwards `textMessage`/`disconnected`/`connected` and only debug-logs `clientEnter` (~lines 219-224); `clientLeave`/`clientMoved` are not handled. `BotInstance.setupTsEvents()` (~lines 132-156) wires tsClient events.
+
+- [ ] **Step 1 — re-emit in client.ts.** Where `clientEnter` is logged, also `this.emit("clientEnter", info)`. Add subscriptions for `clientLeave` and `clientMoved` that `this.emit(...)` them upward (match the existing forwarding style; just propagate, no payload transformation needed since the instance re-queries).
+
+- [ ] **Step 2 — react in instance.ts.** In `setupTsEvents()`, add handlers: on `clientEnter` / `clientLeave` / `clientMoved`, call a small `async refreshOccupancy()` that does `const clients = await this.getClientsInChannel(); this.handleOccupancy(clients.length - 1);` (guarded with try/catch + only when connected). This gives near-instant pause/resume; the 30s poll remains the fallback.
+
+- [ ] **Step 3 — verify:** `npx tsc --noEmit` → 0. `npx vitest run src/bot` → pass.
+- [ ] **Step 4 — commit:** `git add src/ts-protocol/client.ts src/bot/instance.ts && git commit -m "feat(autopause): re-emit client enter/leave/move for instant pause/resume"`
+
+---
+
+## Task 4: API wiring for the toggle
+
+**Files:** Modify `src/web/api/bot.ts`; add/extend a test.
+
+Context: `GET /api/bot/settings` returns `{ idleTimeoutMinutes }`; `POST /api/bot/settings` validates `idleTimeoutMinutes`, sets `config.idleTimeoutMinutes`, `saveConfig`, then loops `botManager.getAllBots()` → `bot.updateIdleTimeout(...)`. This route is `requirePermission("bot.manage")`-gated.
+
+- [ ] **Step 1 — failing API test** (extend the existing bot settings test or add one): `GET /api/bot/settings` returns `autoPauseOnEmpty` (boolean); `POST /api/bot/settings` with `{ autoPauseOnEmpty: false }` persists it (a follow-up GET reflects false) and calls `updateAutoPause` on bots. Model the harness on the existing settings test.
+
+- [ ] **Step 2 — run, expect fail.**
+
+- [ ] **Step 3 — implement.** In `GET /settings`, add `autoPauseOnEmpty: options.config.autoPauseOnEmpty` to the response. In `POST /settings`, if `typeof req.body.autoPauseOnEmpty === "boolean"`, set `config.autoPauseOnEmpty`, include it in the `saveConfig`, and loop bots calling `bot.updateAutoPause(config.autoPauseOnEmpty)`. Keep the existing `idleTimeoutMinutes` handling intact (handle both fields in one save).
+
+- [ ] **Step 4 — verify:** `npx vitest run src/web` → pass; `npx tsc --noEmit` → 0.
+- [ ] **Step 5 — commit:** `git add src/web/api/bot.ts <test> && git commit -m "feat(autopause): expose autoPauseOnEmpty via /api/bot/settings"`
+
+---
+
+## Task 5: Frontend toggle in Settings
+
+**Files:** Modify `web/src/views/Settings.vue` (and the settings load/save it uses).
+
+Context: The **行为设置** section (already `v-if="can('bot.manage')"`) holds the idle-timeout control, loaded via `loadIdleTimeout()` (GET /api/bot/settings) and saved via `saveIdleTimeout()` (POST). Read these first.
+
+- [ ] **Step 1 — implement.** Add an `autoPauseOnEmpty` ref. In the settings load, populate it from the GET response. Add a checkbox/toggle in the 行为设置 section labelled e.g. "频道无人时自动暂停" bound to it, and include `autoPauseOnEmpty` in the POST payload of the save function (alongside `idleTimeoutMinutes`, or via its own save — match the existing pattern). Use existing form/toggle CSS classes.
+- [ ] **Step 2 — verify:** `cd web && npx vue-tsc --noEmit` → exit 0; read template back for correctness.
+- [ ] **Step 3 — commit:** `git add web/src/views/Settings.vue && git commit -m "feat(autopause): autoPauseOnEmpty toggle in Settings"`
+
+---
+
+## Final verification
+- [ ] `npx tsc --noEmit` → 0
+- [ ] `npx vitest run src/` → all pass
+- [ ] `cd web && npx vue-tsc --noEmit` → 0
+- [ ] `npm run build` → succeeds
+- [ ] Manual: with a bot playing, leave its channel → music auto-pauses (no disconnect); rejoin → resumes. Manually pause, leave, rejoin → stays paused. Toggle off in Settings → no auto-pause.

+# Dedicated-link Bot Scoping (+ refresh fix) — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: superpowers:subagent-driven-development. Steps use checkbox (`- [ ]`) syntax.
+
+**Goal:** Opening a dedicated link locks the WebUI to that one bot (selector shows only it, switching disabled, with an explicit exit); the lock is carried in the URL (`?bot=<id>`) so it survives refresh — fixing item 4 too.
+
+**Architecture:** A `scopedBotId` in the Pinia player store is the runtime lock; the URL query `?bot=<id>` is the durable source of truth. A router `beforeEach` syncs scope from the query and re-attaches `?bot` across in-app navigation while scoped. `BotRedirect` seeds it; Navbar renders the lock; graceful clear if the bot doesn't exist.
+
+**Tech:** Vue 3 + Pinia + vue-router, TypeScript. (Frontend isn't unit-tested in this repo → verify via `vue-tsc` + manual; extract one pure helper to unit-test.)

+    expect(resolveScopedBot("b", ["a", "b"])).toBe("b");
+  });
+  it("clears (null) when the requested id is not a known bot", () => {
+    expect(resolveScopedBot("ghost", ["a", "b"])).toBeNull();
+  });
+});
+```
+
+- [ ] **Step 2 — run, expect fail:** `npx vitest run web/src/stores/scope.test.ts` → module missing.
+      (Note: the repo's vitest runs from root; this test lives under web/. If the root vitest config doesn't include web/src, run it via the web workspace: `cd web && npx vitest run src/stores/scope.test.ts`. Use whichever picks it up; confirm it FAILS first.)
+
+- [ ] **Step 3 — implement the helper** (code above).
+
+- [ ] **Step 4 — add scope state to `web/src/stores/player.ts`:**
+  - state: `scopedBotId: null as string | null`.
+  - getter: `isScoped: (state) => state.scopedBotId !== null`.
+  - actions:
+    - `setScope(id: string)` → `this.scopedBotId = id;` and also set `this.activeBotId = id` (scoped == active), then ensure that bot's queue is loaded like `setActiveBotId` does.
+    - `clearScope()` → `this.scopedBotId = null;`.
+    - `applyScopeFromQuery(requestedId: string | null)` → uses `resolveScopedBot(requestedId, this.bots.map(b => b.id))`; if result non-null → `setScope(result)`; if null and a scope was requested → `clearScope()`. (Called after bots are loaded.)
+  - Guard `setActiveBotId(id)`: at the top, `if (this.scopedBotId !== null && id !== this.scopedBotId) return;` so switching is blocked while scoped.
+
+- [ ] **Step 5 — run helper test, expect pass:** `cd web && npx vitest run src/stores/scope.test.ts` → 3 pass. `cd web && npx vue-tsc --noEmit` → exit 0.
+
+- [ ] **Step 6 — commit:** `git add web/src/stores/scope.ts web/src/stores/scope.test.ts web/src/stores/player.ts && git commit -m "feat(scope): player store scopedBotId + resolveScopedBot helper"`
+
+---
+
+## Task 2: Router guard — sync scope from `?bot` + preserve across navigation
+
+**Files:** Modify `web/src/router/index.ts`.
+
+READ the file: the existing `beforeEach` (~lines 36-60) handles needsSetup/auth. Add scope handling AFTER auth resolves (so we don't fight the login redirect). Import the player store (use it inside the guard via `usePlayerStore()` — Pinia is active by the time navigation runs).
+
+- [ ] **Step 1 — implement.** In `beforeEach`, after the existing auth/needsSetup logic decides the navigation is allowed to proceed to `to` (i.e., not redirecting to /login or /first-run), add:
+
+```typescript
+const store = usePlayerStore();
+const qBot = typeof to.query.bot === "string" ? to.query.bot : null;
+if (qBot) {
+  // entering/with a scope in the URL — store will validate against bots later
+  store.scopedBotId = qBot;        // tentative; applyScopeFromQuery (after fetchBots) confirms/clears
+  return next();
+}
+if (store.scopedBotId) {
+  // scoped but this navigation dropped ?bot → re-attach so the lock survives in-app nav + refresh
+  if (to.query.bot !== store.scopedBotId) {
+    return next({ ...to, query: { ...to.query, bot: store.scopedBotId } });
+  }
+}
+return next();
+```
+
+(Adapt to the file's existing `next()` style — it may use `next(...)`/return. Ensure this runs only for allowed navigations, not when redirecting to /login. The exit action in Task 4 calls `store.clearScope()` BEFORE navigating to `/`, so `store.scopedBotId` is null and the re-attach branch is skipped — that's how exit works.)
+
+- [ ] **Step 2 — verify:** `cd web && npx vue-tsc --noEmit` → exit 0. Re-read the guard to ensure no redirect loop (when `to.query.bot === store.scopedBotId`, it does NOT redirect again).
+
+- [ ] **Step 3 — commit:** `git add web/src/router/index.ts && git commit -m "feat(scope): router guard syncs + preserves ?bot across navigation"`
+
+---
+
+## Task 3: BotRedirect seeds the URL scope
+
+**Files:** Modify `web/src/views/BotRedirect.vue`.
+
+READ it: onMounted reads `route.params.id`, ensures `store.fetchBots()`, finds the bot; if found `store.setActiveBotId(id)` + `router.replace('/')`; else shows not-found.
+
+- [ ] **Step 1 — implement.** Change the found-branch to seed scope via the URL instead of bouncing to a bare `/`:
+  - keep the fetchBots + existence check,
+  - if found: `router.replace({ path: '/', query: { bot: botId } })` (the router guard + store will set the scope). Optionally also call `store.setScope(botId)` directly for immediacy.
+  - if not found: unchanged (show "机器人不存在或未加载").
+
+- [ ] **Step 2 — verify:** `cd web && npx vue-tsc --noEmit` → exit 0.
+- [ ] **Step 3 — commit:** `git add web/src/views/BotRedirect.vue && git commit -m "feat(scope): dedicated link seeds ?bot scope instead of bare redirect"`
+
+---
+
+## Task 4: Navbar lock UI + apply-scope-on-load
+
+**Files:** Modify `web/src/components/Navbar.vue`, `web/src/App.vue`.
+
+READ both: Navbar has `controllableBots` (computed) + the dropdown selector + `selectBot`; App.vue onMounted calls `playerStore.fetchBots()` (+ loadTheme/connect).
+
+- [ ] **Step 1 — Navbar lock.** When `store.isScoped`:
+  - render only the scoped bot (a `displayedBots` computed → if scoped, `controllableBots.filter(b => b.id === store.scopedBotId)`, else `controllableBots`),
+  - disable the dropdown open / switching (no chevron, or make the trigger non-interactive) so the user can't switch,
+  - hide other bots' "copy link" affordances (only the scoped bot remains anyway),
+  - show a small "专属模式" badge and an "退出" button → `store.clearScope(); router.push('/')` (clear BEFORE navigating so the guard doesn't re-attach `?bot`). Import `useRouter` if not present.
+  When not scoped: behavior unchanged.
+
+- [ ] **Step 2 — apply scope on load (App.vue).** After `fetchBots()` resolves in onMounted, call `playerStore.applyScopeFromQuery(routeBot)` where `routeBot` is the current `?bot` query (via `useRoute().query.bot` as string|null). This confirms a refreshed `?bot` against the loaded bots and sets activeBotId (or gracefully clears if the bot is gone). (If Task 2's guard already set `scopedBotId` tentatively, this validates it against the now-loaded bot list.)
+
+- [ ] **Step 3 — verify:** `cd web && npx vue-tsc --noEmit` → exit 0. Read templates back for valid syntax; confirm read-only displays aren't broken and the non-scoped path is unchanged.
+- [ ] **Step 4 — commit:** `git add web/src/components/Navbar.vue web/src/App.vue && git commit -m "feat(scope): lock Navbar selector to scoped bot + apply scope on load"`
+
+---
+
+## Final verification
+- [ ] `cd web && npx vue-tsc --noEmit` → exit 0
+- [ ] `npx tsc --noEmit` → exit 0 (backend unaffected)
+- [ ] `cd web && npx vitest run src/stores/scope.test.ts` (or root vitest if it includes web) → pass
+- [ ] `npm run build` → succeeds
+- [ ] Manual: open `/bot/<id>` → URL becomes `/?bot=<id>`, selector shows only that bot, switching disabled; **refresh → still locked** (item 4 fixed); navigate to Search → URL keeps `?bot`; refresh on Search → still locked; click 退出 → back to all bots (`/`, no `?bot`); open `/` directly → full multi-bot control; open `/?bot=<nonexistent>` → gracefully shows all bots (no lock).
+
+## Notes
+- Backend per-bot authorization (PR #80) is the real security boundary; this is a UX lock.
+- No localStorage — URL is the source of truth, so the lock is shareable and self-clearing.
+- Item 4 is fixed as a consequence of carrying `?bot` in the URL across refresh/navigation.

+# WebUI Authentication
+
+**Date:** 2026-05-27
+**Status:** Spec — pending implementation
+**Branch:** `feat/webui-auth`
+
+## Problem
+
+WebUI 的所有后端端点和 WebSocket 当前没有任何鉴权：
+
+- `src/web/server.ts` 注册的 `/api/bot`、`/api/player`、`/api/music`、`/api/auth`、`/api/config/public-url`、`/api/health`、`/ws` 均无中间件拦截。
+- 静态前端通过 `express.static()` 直接对外提供。
+
+后果：任何能访问 WebUI 端口（默认 `3000`）的人都能控制 bot、修改配置、操控播放，并触发对网易云 / QQ / Bilibili 的登录二维码流程。一旦 WebUI 端口暴露公网（无论是直接绑定 `0.0.0.0`、还是经 nginx 反代），即被任意访客接管。
+
+## Goal
+
+为 WebUI 增加用户名 + 密码登录，覆盖所有 HTTP `/api/*` 端点（除显式公共白名单）以及 `/ws` WebSocket，使未登录访客无法调用任何敏感接口或观察 bot 状态。
+
+## Out of Scope（明确不做）
+
+- 登录失败的限流 / 锁定（无 brute-force 防御；可放在反代层；后续 PR 单独做）
+- 角色与权限（admin / viewer）—— 全员同权
+- 密码重置流程（不挂邮件；仅提供登录后 `change-password`）
+- 双因素认证（2FA）
+- "记住我" / 绝对过期 vs 滑动过期的可配置
+- 旧版"无鉴权"兼容开关（`requireAuth=false`）—— 合入后所有部署强制启用鉴权
+- 现有 `config.adminPassword` 字段的迁移 —— 保留为未使用字段，避免破坏旧 `config.json`
+
+## Non-functional Constraints
+
+- 不引入需要原生编译的依赖（Windows 用户多，build tools 不稳定）。密码哈希用纯 JS 的 `bcryptjs`。
+- Cookie 行为必须兼容现有 `trustProxy` 反代部署。
+- 升级路径：旧用户首次启动新版本 → 自动进入 `/setup` 创建首位 admin；期间所有 `/api/*` 仍拒绝访问。期间不存在"裸奔窗口"。
+- 后续维护者要能在不阅读 `requireAuth` 内部细节的情况下，把新路由挂到 `/api/*` 下并自动获得鉴权。
+
+## Architecture
+
+### 数据层（`src/data/`）
+
+扩展 `src/data/database.ts` 的 schema-migration 块，新增两张表：
+
+```sql
+CREATE TABLE IF NOT EXISTS users (
+  id           TEXT PRIMARY KEY,                 -- uuid v4
+  username     TEXT NOT NULL UNIQUE COLLATE NOCASE,
+  passwordHash TEXT NOT NULL,                    -- bcryptjs, 12 rounds
+  createdAt    INTEGER NOT NULL,
+  updatedAt    INTEGER NOT NULL
+);
+
+CREATE TABLE IF NOT EXISTS sessions (
+  id          TEXT PRIMARY KEY,                  -- sha256(rawToken) hex
+  userId      TEXT NOT NULL REFERENCES users(id) ON DELETE CASCADE,
+  createdAt   INTEGER NOT NULL,
+  expiresAt   INTEGER NOT NULL,                  -- ms epoch
+  lastSeenAt  INTEGER NOT NULL
+);
+CREATE INDEX IF NOT EXISTS idx_sessions_userId    ON sessions(userId);
+CREATE INDEX IF NOT EXISTS idx_sessions_expiresAt ON sessions(expiresAt);
+```
+
+**为什么 `sessions.id` 存 sha256(token) 而不是 token 本身：** 若 SQLite 文件被泄露（备份、误传、磁盘扫描），原始 token 会让攻击者直接冒充任意已登录用户。存 hash 后只能爆破。代价仅是每次请求一次 sha256。
+
+新模块：
+
+`src/data/users.ts`
+- `createUser(username, password): User` — 在事务里 INSERT；遇到 UNIQUE 冲突抛出 `UsernameTakenError`
+- `findByUsername(username): User | null`
+- `verifyPassword(plain, hash): Promise<boolean>` — bcryptjs compare
+- `countUsers(): number` — 用于 `/needs-setup`
+- `changePassword(userId, newPassword): void`
+
+`src/data/sessions.ts`
+- `createSession(userId): { token: string; expiresAt: number }` — 生成 32 字节随机 token（`crypto.randomBytes(32).toString('base64url')`），存 sha256
+- `validateAndTouch(rawToken): { userId, username } | null` — 单次 SQL JOIN：查 session + user；过期 → 返回 null + 删除该行；否则若 `now - lastSeenAt > 1h` 则 UPDATE 滑动续期到 `now + 7d`
+- `deleteSession(rawToken): void` — 退出
+- `deleteAllForUser(userId, exceptToken?): void` — change-password 时调用，可保留当前会话
+- `cleanupExpired(): void` — 定时任务
+
+### HTTP 层（`src/web/`）
+
+#### 新增中间件
+
+`src/web/middleware/requireAuth.ts`
+```
+读取 req.cookies.tsmb_session
+  → 缺失 → 401 { error: "unauthenticated" }
+  → 调 sessions.validateAndTouch
+  → null → 清 cookie + 401
+  → 有效 → req.user = { id, username }; next()
+```
+
+`src/web/middleware/csrf.ts`
+```
+若 method ∈ {GET, HEAD, OPTIONS} → next()
+否则要求 req.headers.origin || req.headers.referer 的 host 与 req.get('host') 一致
+  → 不一致或两者都缺失 → 403 { error: "bad origin" }
+```
+
+#### 新路由：`src/web/api/session.ts`
+
+挂在 `/api/session`，全部公共（不挂 requireAuth）：
+
+| Method | Path | 行为 |
+|---|---|---|
+| GET | `/needs-setup` | `{ needsSetup: users.countUsers() === 0 }` |
+| POST | `/setup` | Body `{ username, password }`。在事务内再次检查 `countUsers() === 0`：是则 INSERT user + 立刻 createSession + Set-Cookie + 200 `{ id, username }`；否则 409 `{ error: "already initialized" }` |
+| POST | `/login` | Body `{ username, password }`。匹配则 createSession + Set-Cookie + 200；不匹配则等待 250ms 后 401 `{ error: "invalid credentials" }`（常量时间延迟，降低用户名枚举风险） |
+| POST | `/logout` | 删 session，清 cookie，204 |
+| GET | `/me` | 走 requireAuth；返回 `{ id, username }` |
+| POST | `/change-password` | 走 requireAuth；Body `{ oldPassword, newPassword }`；通过则 changePassword + deleteAllForUser(except 当前) + 204 |
+
+> `/me` 与 `/change-password` 例外地需要 requireAuth —— 在路由内单独挂中间件，避免污染 `/api/session/*` 的公共属性。
+
+#### Cookie 规范
+
+- 名称：`tsmb_session`
+- 值：32 字节 random → base64url
+- 属性：`HttpOnly; SameSite=Lax; Path=/; Max-Age=604800`（7 天）
+- `Secure` 标志：当 `req.secure === true`（依赖 `trustProxy` + `X-Forwarded-Proto`）；本地 HTTP 调试时不加，避免 cookie 被丢弃
+
+#### 装配顺序（`src/web/server.ts`）
+
+```ts
+app.use(express.json({ limit: "400kb" }));
+app.use(cookieParser());                              // 新增
+
+// 公共
+app.get("/api/health", …);
+app.get("/api/config/public-url", …);
+app.use("/api/session", createSessionRouter(...));
+
+// 闸门（仅作用于下方注册的 /api/* 路由）
+app.use("/api", csrfOriginCheck);
+app.use("/api", requireAuth);
+
+// 受保护
+app.use("/api/bot",    createBotRouter(...));
+app.use("/api/music",  createMusicRouter(...));
+app.use("/api/player", createPlayerRouter(...));
+app.use("/api/auth",   createAuthRouter(...));        // 音乐平台 QR
+
+// 静态 SPA（公共，前端自行判定登录态后跳转）
+app.use(express.static(staticDir));
+app.get(/^(?!\/api|\/ws)/, sendIndex);
+```
+
+> Express 的 `app.use` 仅对匹配前缀生效。公共路由先注册即可命中；之后的 `app.use("/api", …)` 闸门只在公共路由未匹配时执行，因此 `/api/health`、`/api/config/public-url`、`/api/session/*` 不会被闸门拦截。
+
+#### 定时清理
+
+`server.start()` 内启动 `setInterval(cleanupExpired, 60 * 60 * 1000)`，`server.stop()` 内 `clearInterval`。
+
+### WebSocket 层（`src/web/websocket.ts` + `src/web/server.ts`）
+
+改造为手动 upgrade：
+
+```ts
+const wss = new WebSocketServer({ noServer: true });
+
+server.on("upgrade", (req, socket, head) => {
+  if (req.url !== "/ws") { socket.destroy(); return; }
+  const session = validateCookieFromHeaders(req.headers.cookie);
+  if (!session) {
+    socket.write("HTTP/1.1 401 Unauthorized\r\nConnection: close\r\n\r\n");
+    socket.destroy();
+    return;
+  }
+  wss.handleUpgrade(req, socket, head, (ws) => {
+    (ws as any).userId = session.userId;
+    wss.emit("connection", ws, req);
+  });
+});
+```
+
+`validateCookieFromHeaders` 在 `src/web/auth/validateSession.ts` 提供，HTTP 中间件与 WS upgrade 共用同一实现，确保不会出现"HTTP 拒、WS 放行"或反之的偏差。
+
+不需要在 upgrade 上单独做 CSRF：浏览器在跨站 WebSocket 请求里仍会带 Origin 头，可在 validate 之外顺手比对 `req.headers.origin` host 与 `req.headers.host` 一致；不一致直接拒绝。
+
+### 前端层（`web/`）
+
+#### 新视图
+
+- `web/src/views/Login.vue` — 用户名 + 密码表单 → POST `/api/session/login` → 成功跳 `next` 或 `/`
+- `web/src/views/FirstRunSetup.vue` — 同样表单 + 二次确认密码 → POST `/api/session/setup` → 成功后自动登录并跳 `/`
+  - 名称避免与既有 `Setup.vue`（bot 创建向导）冲突
+
+#### Session 状态
+
+新增 `web/src/composables/useSession.ts`：暴露 `currentUser: Ref<User|null>`、`refresh()`、`logout()`、`needsSetup: Ref<boolean>`。在 `App.vue` mount 时调用 `refresh()`。
+
+#### 路由守卫（`web/src/router/index.ts`）
+
+- 公共路由：`/login`、`/setup`
+- 全局 `beforeEach`：
+  1. 先 `GET /api/session/needs-setup`（仅在 `needsSetup` 未知时拉一次并缓存）
+  2. `needsSetup === true` 且目标不是 `/setup` → `redirect('/setup')`
+  3. 否则 `GET /api/session/me`，401 且目标非公共路由 → `redirect('/login?next=<path>')`
+
+#### API 客户端
+
+- 所有 `fetch` 改为 `credentials: 'same-origin'`（若现有有 wrapper 则改一处；否则按文件逐个改 —— 实施时由 plan 列出）
+- 包一层 401 拦截器：任意受保护请求返回 401 → 清 `currentUser` → `router.push('/login')`
+
+#### UI
+
+- 顶栏新增已登录用户名 + "退出"按钮（POST `/logout` → `router.push('/login')`）
+- 修改密码入口暂放在已有的"设置"页签内（若无则新增极简 section）
+
+### 依赖
+
+新增到 `package.json`：
+
+```
+"bcryptjs": "^2.4.3",
+"cookie-parser": "^1.4.6",
+"@types/bcryptjs": "^2.4.6",
+"@types/cookie-parser": "^1.4.7"
+```
+
+不引入 `express-session`、`jsonwebtoken`、`passport` 等更大栈。
+
+## Data Flow
+
+### 首次启动
+
+```
+Browser → GET /         → static SPA
+SPA mounted → GET /api/session/needs-setup → { needsSetup: true }
+SPA → router.replace('/setup')
+User submits form → POST /api/session/setup
+Server (TX): countUsers() === 0 → INSERT user → createSession → Set-Cookie → 200
+SPA → currentUser refresh → router.replace('/')
+```
+
+### 已部署用户升级
+
+旧 `config.adminPassword` 字段保留不动；首次启动新版本仍会因 `users` 表为空而进入 setup 流程 —— 旧字段不被采纳，避免歧义。
+
+### 后续登录
+
+```
+SPA → GET /api/session/me → 401
+SPA → router.replace('/login?next=/queue')
+User submits → POST /api/session/login → Set-Cookie + 200
+SPA → currentUser refresh → router.replace('/queue')
+```
+
+### 受保护请求
+
+```
+SPA → fetch('/api/bot', { credentials: 'same-origin' })
+Server requireAuth: validateAndTouch(cookie)
+  → ok → req.user 注入 → 业务路由处理
+  → 不 ok → 401 → SPA 拦截器跳 /login
+```
+
+### WebSocket
+
+```
+SPA → new WebSocket(`${wsScheme}://${host}/ws`)   // 浏览器自动带 cookie
+Server upgrade handler: validateCookieFromHeaders
+  → ok → handleUpgrade → connection event
+  → 不 ok → HTTP 401 写回原始 socket → destroy
+```
+
+## Error Handling
+
+| 场景 | HTTP 响应 | 备注 |
+|---|---|---|
+| 未带 cookie | 401 `{ error: "unauthenticated" }` | requireAuth |
+| Cookie 解析失败 / token 不存在 | 401 + `Set-Cookie tsmb_session=; Max-Age=0` 清掉 | 自愈 |
+| Session 过期 | 同上 + DELETE 该行 | validateAndTouch 内部完成 |
+| 用户名/密码不匹配 | 401 `{ error: "invalid credentials" }` + 250ms 延迟 | 不区分"用户不存在"和"密码错"两类 |
+| `setup` 时已存在用户 | 409 `{ error: "already initialized" }` | 防止重复初始化 |
+| `setup` 用户名重复 | 在 `/setup` 流程中不可能（只允许 0 → 1） |  |
+| `change-password` 旧密码错 | 401 `{ error: "invalid credentials" }` |  |
+| CSRF Origin 不匹配 | 403 `{ error: "bad origin" }` |  |
+| WS 无 cookie / 校验失败 | 写回 HTTP/1.1 401 并 destroy socket | 在握手前拒绝，避免 onopen 假成功 |
+
+所有错误响应统一 `{ error: string }` 形式，匹配现有 API 风格。
+
+## Testing Strategy
+
+### 单元（vitest）
+
+`src/data/users.test.ts`
+- createUser 成功后 findByUsername 命中（大小写不敏感）
+- 重复 username 抛 UsernameTakenError
+- verifyPassword 正反例
+- changePassword 之后旧哈希不再验证通过
+
+`src/data/sessions.test.ts`
+- createSession 返回的 token 不是 DB 内 id（DB 内是 sha256(token)）
+- validateAndTouch 过期记录返回 null 且记录被删
+- validateAndTouch 未过 1h 不写 DB；过 1h 后写 DB（用 `Date.now` mock 验证）
+- deleteAllForUser(exceptToken) 保留指定会话
+
+### 集成（vitest + supertest，真 SQLite in-memory）
+
+`src/web/api/session.test.ts`
+- empty DB → /needs-setup 返回 true；/setup 成功；/needs-setup 再调返回 false；二次 /setup 返回 409
+- /login 成功后受保护路由 (`GET /api/bot`) 200；不带 cookie 401
+- /logout 之后同一 cookie 调受保护路由 401
+- /change-password 后 a) 旧密码 /login 失败 b) 新密码 /login 成功 c) 之前签发的其他 cookie 失效，当前 cookie 仍可用
+
+`src/web/middleware/csrf.test.ts`
+- 带匹配 Origin 的 POST 通过
+- Origin 与 host 不匹配 → 403
+- 同样规则适用 Referer
+- GET 永远通过
+
+`src/web/websocket.test.ts`（新增或扩展）
+- 无 cookie 的 ws 握手 → 收到 HTTP 401，socket 关闭
+- 带有效 cookie → 握手成功，收到 init 消息
+- Session 删除后已建立的 ws **不会**被主动断（明确记录此妥协 —— 见 Trade-offs）
+
+### 前端
+
+不在本 PR 引入新的 e2e 框架。手动用例（在 PR 描述里列）：
+- 全新数据库启动 → 自动跳 /setup → 创建账户 → 进入主界面
+- 退出 → 自动跳 /login
+- 关闭浏览器 7 天内再开 → 仍登录
+- 登录态下后端重启清空 sessions → 任意 API 调用 → 自动跳 /login

+## Trade-offs / 已知妥协
+
+1. **会话失效不主动断 WS** —— 后台 deleteSession 后，已有 WS 仍在跑（直到客户端断或服务端进程重启）。原因：WS 长连接没有"每条消息再次鉴权"的廉价手段；为此引入会浪费时间。影响面有限：WS 只推状态、不接收 mutating 命令；所有写操作仍走 HTTP。
+2. **无登录限流** —— 见 Out of Scope。若部署面向公网，建议在反代层加 limit（如 nginx `limit_req`）。
+3. **`config.adminPassword` 留作未使用字段** —— 不迁移、不读取。后续 PR 可移除并加 schema migration。当前保留是为避免破坏旧 `config.json` 解析。
+4. **单一管理员模型** —— 多用户表已存在，但 UI 当前不暴露增删用户。下一个 PR 再加用户管理界面。
+5. **Origin/Referer CSRF 检查** —— 不是 token，但配合 `SameSite=Lax` 已能挡掉常规 CSRF 攻击。代价：会拒绝缺 Origin/Referer 的非浏览器客户端 POST 请求（如裸 curl）—— 这是预期行为。

+# Fine-grained account permissions — design
+
+**Issue:** [#79](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/issues/79) (item E — the maintainer's permission-management idea)
+**Date:** 2026-05-30
+**Status:** Approved (brainstorm), pending implementation plan
+
+## Scope
+
+Issue #79 bundles five things. This spec covers **only item E**: allow an admin to
+grant each non-admin (member) account a set of capabilities and a list of bots they
+may control. The other items are handled in separate PRs and are **out of scope**
+here:
+
+- #1 Guest mode (login-less playback)
+- #2 Dedicated-link hides other bots (subsumed conceptually by E's bot allow-list, but the link-specific UX is separate)
+- #3 Auto-pause when channel empty
+- #4 Dedicated link loses bot binding on refresh (a bug)
+
+## Problem
+
+Today the bot has a coarse two-role system: `admin | member` (single `role` column,
+read live per request). `requireAdmin` gates only `/api/users` and `/api/audit`.
+**Every other action — create/edit/delete bots, start/stop, all playback & queue
+control, set platform login cookies, set audio quality — is open to any logged-in
+member, on every bot.** Admins want to delegate limited control to members without
+handing them full power.
+
+## Decisions (from brainstorm)
+
+1. **Model = capability flags + per-member bot allow-list** (not a per-bot×per-action
+   matrix, not role templates).
+2. **Defaults:** on upgrade, existing members are backfilled with full capabilities +
+   all bots (no behavior change); newly-created members get a **basic tier**.
+3. **Bot allow-list semantics:** an explicit "all bots" toggle OR a specific list;
+   empty list = no bots controllable. Members **cannot see** bots outside their
+   allow-list (hidden, not merely disabled).
+4. **Capability set (5 toggles)** — see below; basic tier = playback + queue + all bots.
+5. **Admin is a super-user** (bypasses all checks). The last admin cannot be demoted
+   (existing invariant preserved). Permission grants/revokes are written to the
+   existing audit log.
+
+## Capability taxonomy
+
+| Capability token | Covers | Scope |
+|---|---|---|
+| `player.control` | play/pause/resume/next/prev/stop/seek/volume/mode | per-bot (allow-list) |
+| `player.queue` | search-add / clear / remove / play-at / playlist / album / play-song | per-bot (allow-list) |
+| `bot.manage` | create / edit / delete / start / stop / avatar / profile / idle settings | global (create) + per-bot (operate a specific bot) |
+| `platform.auth` | set NetEase/QQ/Bilibili cookie, QR, SMS | **global** (shared credentials) |
+| `quality` | set audio quality per platform | **global** |
+
+Bot scope is independent of capabilities: a member with `player.control` can only
+exercise it on bots in their allow-list (or all, if the "all bots" flag is set).
+`platform.auth` and `quality` are global capabilities with no bot scope.
+
+**Basic tier** (new members): `{ player.control, player.queue }` + `bots.all = true`.
+A new member can play/queue on every bot but cannot manage bots, change credentials,
+or change quality.
+
+## Data model (SQLite, additive — follows existing `CREATE TABLE IF NOT EXISTS` pattern)
+
+```sql
+-- capability tokens + the "all bots" flag (stored as token 'bots.all')
+CREATE TABLE IF NOT EXISTS user_permissions (
+  userId     TEXT NOT NULL,
+  permission TEXT NOT NULL,
+  PRIMARY KEY (userId, permission),
+  FOREIGN KEY (userId) REFERENCES users(id) ON DELETE CASCADE
+);
+
+-- specific bot allow-list (only consulted when 'bots.all' is NOT present)
+CREATE TABLE IF NOT EXISTS user_bot_access (
+  userId TEXT NOT NULL,
+  botId  TEXT NOT NULL,
+  PRIMARY KEY (userId, botId),
+  FOREIGN KEY (userId) REFERENCES users(id) ON DELETE CASCADE
+);
+CREATE INDEX IF NOT EXISTS idx_user_bot_access_userId ON user_bot_access(userId);
+```
+
+- Admins have no rows (they bypass). Only members are constrained.
+- `bots.all` present ⇒ all bots (incl. future ones). Absent ⇒ only `user_bot_access`
+  rows; empty ⇒ none.
+- `foreign_keys = ON` and WAL are already enabled; cascade-on-user-delete works.
+- `user_bot_access.botId` references bot instance ids; when a bot is deleted, its
+  access rows should be cleaned up (either an FK to the bot table if one exists, or an
+  explicit cleanup in `BotManager.removeBot` / `PermissionStore.pruneBot(botId)`).
+
+New `PermissionStore` in `src/data/permissions.ts` (mirrors `createUserStore` /
+`createSessionStore`: prepared statements + an interface). Methods:
+`getCapabilities(userId)`, `getBotAccess(userId)` → `'all' | string[]`,
+`setPermissions(userId, { capabilities, bots })`, `pruneBot(botId)`.
+
+## Backend enforcement (real 403 — not just hidden UI)
+
+- **`req.user` widened** to carry `capabilities: Set<string>` and bot access. Loaded in
+  `requireAuth` (one extra lookup, or a JOIN in the session query). The same
+  `{id,username,role,capabilities,bots}` shape must be kept in sync in the three places
+  it is built today: `requireAuth.ts`, `session.ts` `requireAuthInline`, and the WS
+  upgrade handler in `server.ts` (WS only needs it if a push action becomes gated).
+  Because it's read live, permission changes take effect immediately (no re-login).
+- **`requirePermission(cap)`** middleware (new, mirrors `requireAdmin.ts`): 401 if no
+  user; allow if `role === 'admin'` or `capabilities.has(cap)`; else 403.
+- **`requireBotAccess`** helper: allow if admin or `bots.all` or botId ∈ access list;
+  else 403. Mounted on the player router's existing `/:botId` choke-point
+  (`src/web/api/player.ts`) and on each `:id` route in `src/web/api/bot.ts`
+  (start/stop/edit/delete/avatar/profile).
+- **Route → capability mapping:**
+  - `/api/player/:botId/*` playback actions → `player.control` (+ `requireBotAccess`)
+  - `/api/player/:botId/*` queue actions → `player.queue` (+ `requireBotAccess`)
+  - `/api/bot` create, `/api/bot/:id` edit/delete, `/api/bot/:id/start|stop|avatar|profile`, `/api/bot/settings` → `bot.manage` (+ `requireBotAccess` for the `:id` ones)
+  - `/api/auth/*` (cookie/QR/SMS) → `platform.auth`
+  - `/api/music/quality` POST → `quality`
+- **`GET /api/bot`** filters its result to the caller's allowed bots for members
+  (admins see all). This is what "hides" disallowed bots in the UI.
+
+## Management API (admin-only, added to the existing users router)
+
+- `GET /api/users/:id/permissions` → `{ capabilities: string[], bots: 'all' | string[] }`
+- `PUT /api/users/:id/permissions` → body `{ capabilities, bots }`; validates tokens
+  against the known set and botIds against existing bots; writes audit
+  `user.permissions_changed`.
+- `GET /api/session/me` is extended to include the **current** user's
+  `{ capabilities, bots }` so the frontend can gate UI. (admins report effectively-all.)
+
+## Frontend
+
+- `useSession` extends `User` with `capabilities` + bot scope and exposes
+  `can(cap)` and `canControlBot(botId)` helpers.
+- **Navbar bot selector** filters `store.bots` to controllable bots (others hidden);
+  `activeBot` fallback and `fetchBots` default only ever land on an allowed bot.
+- **Player / Settings** hide controls and whole sections a member lacks: platform
+  login, audio quality, and bot create/edit/delete are hidden without the matching
+  capability; playback/queue buttons hidden without `player.control` / `player.queue`.
+- **Admin permission editor:** in the Settings → User Management list, each member row
+  gets a "权限" editor — capability checkboxes + a bot allow-list with an "全部机器人"
+  toggle. Saving calls `PUT /api/users/:id/permissions`.
+
+## Defaults & migration
+
+- New tables created idempotently in `initTables`.
+- **One-time backfill** (guarded so it runs once): every existing `member` gets all
+  five capabilities + `bots.all`. Admins are skipped (they bypass). This preserves
+  current behavior for existing members on upgrade.
+- **New member default** (`POST /api/users` with role member): capabilities
+  `{ player.control, player.queue }` + `bots.all` (basic tier).
+- Pre-existing accounts default to `role = 'admin'` per the current schema — those are
+  super-users and unaffected.
+
+## Testing (TDD)
+
+- `PermissionStore` unit tests (set/get capabilities + bot access; `'all'` vs list vs
+  empty; `pruneBot`).
+- `requirePermission` / `requireBotAccess` middleware tests (admin bypass; has/lacks
+  cap → 200/403; bot in/out of allow-list; `bots.all`).
+- API tests: member without cap → 403; with cap → 200; bot not allowed → 403/hidden;
+  `GET /api/bot` filtered for members, full for admin; `PUT .../permissions` validates
+  + audits.
+- Migration test: existing members backfilled to full + `bots.all`; new member gets
+  basic tier.
+
+## Non-goals
+
+- No per-bot×per-capability matrix, no custom role templates (YAGNI).
+- Guest mode, dedicated-link UX, auto-pause, and the refresh bug (#1–#4) are separate.
+- No change to the admin/member role concept itself; this layers capabilities under
+  the existing `member` role.

+# Auto-pause on empty channel — design
+
+**Issue:** [#79](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/issues/79) item 3
+**Date:** 2026-05-30
+**Status:** Approved (brainstorm), pending implementation plan
+
+## Problem
+
+When everyone leaves the bot's voice channel, music keeps playing to an empty room.
+The maintainer wants an option to **auto-pause when the channel is empty** (no disconnect)
+and resume when someone returns.
+
+## Decisions (from brainstorm)
+
+- **Global toggle**, reusing the **already-declared but currently dead** `config.autoPauseOnEmpty`
+  (`src/data/config.ts`, default `true`). No per-bot granularity (YAGNI).
+- **Event-driven, near-instant** reaction (not the 30s poll alone) — subscribe to TS client
+  enter/leave/move events; keep the existing 30s idle poll as a fallback.
+- **Auto-resume only what we auto-paused** — a user-paused track is never auto-resumed.
+- Independent of the existing **idle-disconnect** (`idleTimeoutMinutes`): both share the same
+  emptiness signal but act independently (pause immediately; disconnect after N minutes).
+
+## Current state (verified)
+
+- `client.ts` `getClientsInChannel()` returns all clients in the bot's channel *including the
+  bot*; callers compute "others" as `length - 1`. No persistent roster.
+- The library emits `clientEnter` / `clientLeave` / `clientMoved`; `client.ts` currently only
+  *logs* `clientEnter` and does not re-emit leave/moved.
+- The idle poller in `instance.ts` (`_startIdlePoller`, every 30s) already computes
+  `userCount = getClientsInChannel().length - 1` and, when `<= 0`, schedules an
+  idle-disconnect after `idleTimeoutMinutes`.
+- `player.pause()` / `player.resume()` already pause/resume **without disconnecting** (ffmpeg
+  stays alive, no voice sent). The player only knows `idle|playing|paused` — there is **no**
+  auto-vs-user-pause distinction today.
+- `BotConfig.autoPauseOnEmpty` exists (default true) but is **read nowhere**.
+
+## Design
+
+### Occupancy signal (shared)
+Extract the idle poller's count into one method on `BotInstance`:
+`checkChannelOccupancy()` → queries `getClientsInChannel()`, computes `userCount = length - 1`,
+and drives **both** the existing idle-disconnect timer (unchanged behavior) **and** the new
+auto-pause logic below. It is called by:
+1. the existing 30s poll (fallback), and
+2. new TS event handlers.
+
+### Event subscription
+`client.ts`: subscribe to and **re-emit** `clientEnter`, `clientLeave`, `clientMoved` up to
+`BotInstance`. `BotInstance.setupTsEvents()` calls `checkChannelOccupancy()` on each (a re-query
+is simplest, since `clientLeave` carries no channel id). This gives near-instant pause/resume;
+the poll remains as a safety net.
+
+### Auto-pause logic (inside `checkChannelOccupancy`)
+Add a private `autoPaused = false` flag to `BotInstance`.
+- **Empty** (`userCount <= 0`): if `config.autoPauseOnEmpty` **and** `player.getState() === "playing"`
+  → `player.pause()`, `autoPaused = true`, emit `stateChange`. (Idle-disconnect timer still
+  scheduled as today.)
+- **Re-populated** (`userCount > 0`): if `autoPaused` **and** `player.getState() === "paused"`
+  → `player.resume()`, `autoPaused = false`, emit `stateChange`. (Idle timer cancelled as today.)
+
+### `autoPaused` bookkeeping (so user pauses are respected)
+Clear `autoPaused = false` in `cmdPause`, `cmdResume`, `cmdStop`, `cmdPlay`, and on
+connect/disconnect (the `disconnected` handler calls `player.stop()` → idle). Net effect: only a
+track *we* auto-paused gets auto-resumed; a user-paused track stays paused when someone returns.
+
+### Config wiring
+- `GET /api/bot/settings`: include `autoPauseOnEmpty` in the payload (alongside `idleTimeoutMinutes`).
+- `POST /api/bot/settings`: accept + validate a boolean `autoPauseOnEmpty`, `saveConfig`, and
+  propagate to live bots via a new `BotInstance.updateAutoPause(enabled)` (mirrors
+  `updateIdleTimeout`). Since the instance reads `this.config.autoPauseOnEmpty` live, propagation
+  can be as simple as updating the stored config reference / a field the check reads.
+- Frontend `Settings.vue` → the **行为设置** section (already `bot.manage`-gated): add a toggle
+  for `autoPauseOnEmpty` next to the idle-timeout control; load it in the settings fetch and send
+  it on save.
+
+## Components / files
+
+- `src/ts-protocol/client.ts` — subscribe + re-emit `clientEnter`/`clientLeave`/`clientMoved`.
+- `src/bot/instance.ts` — `autoPaused` field; `checkChannelOccupancy()` (refactored from the
+  idle poller, drives idle + auto-pause); event handlers; clear `autoPaused` in user commands +
+  connect/disconnect; `updateAutoPause(enabled)`.
+- `src/web/api/bot.ts` — `GET`/`POST /settings` handle `autoPauseOnEmpty`.
+- `web/src/views/Settings.vue` (+ player store settings load/save) — the toggle.
+- `src/data/config.ts` — field already exists (no change beyond confirming default).
+
+## Testing
+
+- **Decision unit test (TDD):** extract the pause/resume decision into a testable method, e.g.
+  `applyOccupancy(userCount)` operating on an injected fake player (`getState`/`pause`/`resume`)
+  + the `autoPaused` flag + the config flag. Cases: empty+playing+enabled → pause + `autoPaused`;
+  re-populated+`autoPaused`+paused → resume + clear; re-populated when NOT `autoPaused` (user
+  pause) → no resume; flag disabled → no pause; empty while idle (not playing) → no-op.
+- **API test:** `GET`/`POST /api/bot/settings` round-trips `autoPauseOnEmpty` (validates boolean,
+  persists, propagates).
+- Live TS event wiring is verified by code review + a manual run (can't unit-test a real server).
+
+## Non-goals
+
+- No per-bot toggle (global only). No change to idle-disconnect behavior. No new dependency.
+- Reaction relies on events the bot can already see (same-channel members are always in view);
+  no extra channel subscription needed.

+# Dedicated-link bot scoping (+ refresh fix) — design
+
+**Issue:** [#79](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/issues/79) items 2 and 4
+**Date:** 2026-05-30
+**Status:** Approved (brainstorm), pending implementation plan
+
+## Problem
+
+- **Item 2:** A dedicated link (`/bot/:id`) is meant to give someone control of *one* bot, but today it just sets the active bot and bounces to `/`; the user can still switch to any other bot from the top-right selector.
+- **Item 4 (bug):** After opening a dedicated link, refreshing the page loses the bot — the UI falls back to the first bot.
+
+Root cause (verified): `BotRedirect.vue` does `router.replace('/')` (dropping the id), and `activeBotId` is in-memory-only Pinia state with no persistence, so a reload resets it to `bots[0]`.
+
+## Decision (from brainstorm: Q2 = URL-carried scope)
+
+Carry the scoped bot in the **URL query** (`?bot=<id>`). One mechanism fixes **both** items: the URL is durable across refresh (item 4) and shareable/self-clearing, and the frontend locks the selector to the scoped bot (item 2). No localStorage sticky-lock; plain `/` (no `?bot`) = full control. Backend per-bot authorization (PR #80) remains the real boundary — this is a UX lock.
+
+## Design
+
+### Scope state (store)
+Add to the player store:
+- `scopedBotId: string | null` — the bot the UI is locked to.
+- getter `isScoped` = `scopedBotId !== null`.
+- action `setScope(id)` / `clearScope()`.
+- `setActiveBotId(id)` becomes a no-op (or ignores) when `isScoped` and `id !== scopedBotId`, so stray switch attempts can't change bots.
+
+### URL as the durable source of truth
+- `BotRedirect.vue` (`/bot/:id`): instead of `router.replace('/')`, validate the bot exists, then `router.replace({ path: '/', query: { bot: id } })`. (Keeps the "clean" home URL but with `?bot=`.)
+- **Router `beforeEach` guard** (the heart of it):
+  - If `to.query.bot` is present → `store.setScope(to.query.bot)` and continue.
+  - Else if `store.isScoped` (a scope is active and this navigation dropped the param) → redirect to the same route **with** `query.bot = store.scopedBotId` re-attached (so the lock survives in-app navigation to /search, /library, etc.).
+  - Else → no scope; continue.
+  This keeps `?bot=` on the URL for every route while scoped, so a refresh on *any* route re-establishes the lock → **fixes item 4**.
+- On app load / after `fetchBots()`: apply `scopedBotId`/`?bot` to `activeBotId`; if the scoped bot doesn't exist or isn't in the user's allowed set, **clear the scope gracefully** (fall back to normal multi-bot view) rather than locking onto a dead id.
+
+### Exit
+- `clearScope()` sets `scopedBotId = null`; the exit affordance navigates to `/` *after* clearing, so the guard won't re-attach `?bot`. This is the only way to leave scoped mode (self-clearing, intentional).
+
+### Navbar (the lock UI)
+- When `isScoped`: the bot selector shows **only** the scoped bot, the dropdown/switching is disabled (no chevron / non-interactive), and other bots' "copy link" affordances are not shown.
+- Show a small "专属模式" indicator with an "退出" control → `clearScope()` + navigate to `/`.
+- When not scoped: unchanged (full selector over `controllableBots`).
+
+### Active-bot coherence
+Because every player action already routes through `activeBotId`, locking `activeBotId === scopedBotId` guarantees all controls affect only the scoped bot. The store's `activeBot` getter `bots[0]` fallback still degrades safely if the scoped id ever fails to match (combined with the graceful-clear above).
+
+## Components / files
+
+- `web/src/stores/player.ts` — `scopedBotId` state, `isScoped`, `setScope`/`clearScope`, guard in `setActiveBotId`, apply scope→active in `fetchBots`/init (graceful clear if missing).
+- `web/src/router/index.ts` — `beforeEach` scope sync + `?bot` preservation.
+- `web/src/views/BotRedirect.vue` — set scope + `replace({ path: '/', query: { bot: id } })`.
+- `web/src/components/Navbar.vue` — locked selector + "专属模式/退出" affordance.
+- `web/src/App.vue` — ensure scope is applied to `activeBotId` after `fetchBots` on load (if not already handled by the store/guard).
+
+## Testing
+
+Vue UI isn't unit-tested in this repo, so verification is `vue-tsc` + manual run. The **store scope logic is testable** if a lightweight test harness exists for Pinia stores; otherwise assert the pure pieces:
+- `setActiveBotId` ignores a switch to a non-scoped bot while scoped; allows the scoped bot.
+- `clearScope` resets state.
+- A small helper for "resolve scope from query + bots list → {scopedBotId, activeBotId} or cleared-if-missing" can be extracted and unit-tested.
+Manual: open `/bot/<id>` → locked to that bot, selector shows only it; refresh → still locked (item 4 fixed); navigate to Search then refresh → still locked; click 退出 → back to all bots; open `/` directly → full control (no lock).
+
+## Non-goals
+
+- No localStorage persistence (URL is the source of truth). No backend change (per-bot auth already exists in #80). No change to how dedicated links are generated (still `<base>/bot/<id>`); only what happens when one is opened.
