+# Frontend Routing 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 URL-backed frontend routes for login, book list, book workspace, and admin.
+
+**Architecture:** Keep route ownership in `src/App.vue` and leave page components event-driven. Use `window.history.pushState`, `window.history.replaceState`, and `popstate` to maintain one small local route state without adding dependencies.
+
+**Tech Stack:** Vue 3 Composition API, Vite, Vitest, Vue Test Utils, browser History API.
+
+---
+
+## File Structure
+
+- Modify `src/App.test.ts` for TDD coverage of URL-backed navigation and logged-out redirects.
+- Modify `src/App.vue` to replace local `currentBookId` / `showAdmin` view state with parsed route state.
+- Do not modify `package.json` or `package-lock.json`; existing user changes there are unrelated.
+
+## Task 1: Add failing route tests
+
+**Files:**
+- Modify: `src/App.test.ts`
+- Test: `src/App.test.ts`
+
+- [ ] **Step 1: Replace the auth mock with mutable test state**
+
+Use a hoisted auth state so each test can switch between logged-in and logged-out behavior:
+
+```ts
+const authState = vi.hoisted(() => {
+  const { computed, ref } = require('vue') as typeof import('vue')
+  return {
+    loggedIn: ref(true),
+    user: ref(null),
+    fetchMe: vi.fn(),
+  }
+})
+
+vi.mock('./composables/useAuth', () => ({
+  useAuth: () => ({
+    isLoggedIn: computed(() => authState.loggedIn.value),
+    fetchMe: authState.fetchMe,
+    user: authState.user,
+  }),
+}))
+```
+
+- [ ] **Step 2: Reset URL and auth state before each test**
+
+Add this to the existing `beforeEach`:
+
+```ts
+authState.loggedIn.value = true
+authState.user.value = null
+authState.fetchMe.mockReset()
+window.history.replaceState(null, '', '/books')
+```
+
+- [ ] **Step 3: Add tests for the route behaviors**
+
+Add these tests:
+
+```ts
+it('opens a book route when a book is selected', async () => {
+  vi.mocked(booksApi.listBooks).mockResolvedValue([
+    { id: 'b1', name: '示例整本', updatedAt: '2026-01-01T00:00:00.000Z', lessonCount: 0 },
+  ])
+  vi.mocked(booksApi.getBook).mockResolvedValue({
+    id: 'b1',
+    name: '示例整本',
+    updatedAt: '2026-01-01T00:00:00.000Z',
+    data: createEmptyBook(),
+  })
+
+  const wrapper = mount(App)
+  await flushPromises()
+
+  await wrapper.get('[data-testid="open-b1"]').trigger('click')
+  await flushPromises()
+
+  expect(window.location.pathname).toBe('/books/b1')
+  expect(wrapper.find('[data-testid="back"]').exists()).toBe(true)
+})
+
+it('returns to the books route from the workspace', async () => {
+  vi.mocked(booksApi.listBooks).mockResolvedValue([
+    { id: 'b1', name: '示例整本', updatedAt: '2026-01-01T00:00:00.000Z', lessonCount: 0 },
+  ])
+  vi.mocked(booksApi.getBook).mockResolvedValue({
+    id: 'b1',
+    name: '示例整本',
+    updatedAt: '2026-01-01T00:00:00.000Z',
+    data: createEmptyBook(),
+  })
+
+  const wrapper = mount(App)
+  await flushPromises()
+
+  await wrapper.get('[data-testid="open-b1"]').trigger('click')
+  await flushPromises()
+  await wrapper.get('[data-testid="back"]').trigger('click')
+  await flushPromises()
+
+  expect(window.location.pathname).toBe('/books')
+  expect(wrapper.text()).toContain('教学设计')
+})
+
+it('opens the admin route from the book list', async () => {
+  authState.user.value = { id: 'u1', username: 'admin', role: 'admin' }
+  vi.mocked(booksApi.listBooks).mockResolvedValue([])
+
+  const wrapper = mount(App)
+  await flushPromises()
+
+  await wrapper.get('button').trigger('click')
+  await flushPromises()
+
+  expect(window.location.pathname).toBe('/admin')
+  expect(wrapper.text()).toContain('用户管理')
+})
+
+it('routes logged-out users to login', async () => {
+  authState.loggedIn.value = false
+  window.history.replaceState(null, '', '/books/b1')
+
+  const wrapper = mount(App)
+  await flushPromises()
+
+  expect(window.location.pathname).toBe('/login')
+  expect(wrapper.text()).toContain('登录')
+})
+```
+
+- [ ] **Step 4: Run test to verify RED**
+
+Run:
+
+```bash
+rtk npm test -- src/App.test.ts
+```
+
+Expected: FAIL because `App.vue` does not update `window.location.pathname` for book/admin navigation and does not redirect logged-out users.
+
+## Task 2: Implement route state in App.vue
+
+**Files:**
+- Modify: `src/App.vue`
+- Test: `src/App.test.ts`
+
+- [ ] **Step 1: Replace local page flags with route state**
+
+In `src/App.vue`, replace `currentBookId` and `showAdmin` with this route model:
+
+```ts
+type AppRoute =
+  | { name: 'login' }
+  | { name: 'books' }
+  | { name: 'book'; bookId: string }
+  | { name: 'admin' }
+
+const route = ref<AppRoute>(parseRoute(window.location.pathname))
+```
+
+- [ ] **Step 2: Add route parsing and navigation helpers**
+
+Add helpers in `src/App.vue`:
+
+```ts
+function parseRoute(pathname: string): AppRoute {
+  if (pathname === '/login') return { name: 'login' }
+  if (pathname === '/admin') return { name: 'admin' }
+  if (pathname === '/books') return { name: 'books' }
+
+  const bookMatch = pathname.match(/^\/books\/([^/]+)$/)
+  if (bookMatch?.[1]) {
+    return { name: 'book', bookId: decodeURIComponent(bookMatch[1]) }
+  }
+
+  return { name: 'books' }
+}
+
+function routeToPath(nextRoute: AppRoute): string {
+  if (nextRoute.name === 'login') return '/login'
+  if (nextRoute.name === 'admin') return '/admin'
+  if (nextRoute.name === 'book') return `/books/${encodeURIComponent(nextRoute.bookId)}`
+  return '/books'
+}
+
+function replaceRoute(nextRoute: AppRoute): void {
+  const path = routeToPath(nextRoute)
+  route.value = nextRoute
+  if (window.location.pathname !== path) {
+    window.history.replaceState(null, '', path)
+  }
+}
+
+function pushRoute(nextRoute: AppRoute): void {
+  const path = routeToPath(nextRoute)
+  route.value = nextRoute
+  if (window.location.pathname !== path) {
+    window.history.pushState(null, '', path)
+  }
+}
+```
+
+- [ ] **Step 3: Wire mount, popstate, and auth redirects**
+
+Update imports and lifecycle:
+
+```ts
+import { onBeforeUnmount, onMounted, ref, watch } from 'vue'
+```
+
+Use:
+
+```ts
+function syncRouteForAuth(): void {
+  if (!isLoggedIn.value) {
+    replaceRoute({ name: 'login' })
+    return
+  }
+  if (route.value.name === 'login') {
+    replaceRoute({ name: 'books' })
+  }
+}
+
+function handlePopState(): void {
+  route.value = parseRoute(window.location.pathname)
+  syncRouteForAuth()
+}
+
+onMounted(async () => {
+  window.addEventListener('popstate', handlePopState)
+  await fetchMe()
+  syncRouteForAuth()
+})
+
+onBeforeUnmount(() => {
+  window.removeEventListener('popstate', handlePopState)
+})
+
+watch(isLoggedIn, syncRouteForAuth)
+```
+
+- [ ] **Step 4: Map existing component events to route navigation**
+
+Use:
+
+```ts
+async function handleLoginSuccess(): Promise<void> {
+  await fetchMe()
+  pushRoute({ name: 'books' })
+}
+
+function openBook(id: string): void {
+  pushRoute({ name: 'book', bookId: id })
+}
+
+function backToList(): void {
+  pushRoute({ name: 'books' })
+}
+
+function openAdmin(): void {
+  pushRoute({ name: 'admin' })
+}
+```
+
+- [ ] **Step 5: Update template route conditions**
+
+Use:
+
+```vue
+<LoginPage v-if="route.name === 'login'" @success="handleLoginSuccess" />
+<template v-else>
+  <AdminPage v-if="route.name === 'admin'" @back="backToList" />
+  <WorkspaceView
+    v-else-if="route.name === 'book'"
+    :key="route.bookId"
+    :book-id="route.bookId"
+    @back="backToList"
+  />
+  <BookListPage v-else @open="openBook" @admin="openAdmin" />
+</template>
+```
+
+- [ ] **Step 6: Run test to verify GREEN**
+
+Run:
+
+```bash
+rtk npm test -- src/App.test.ts
+```
+
+Expected: PASS for all `App.test.ts` cases.
+
+## Task 3: Final verification
+
+**Files:**
+- Verify: `src/App.vue`
+- Verify: `src/App.test.ts`
+
+- [ ] **Step 1: Run focused tests**
+
+Run:
+
+```bash
+rtk npm test -- src/App.test.ts
+```
+
+Expected: PASS.
+
+- [ ] **Step 2: Run full frontend test suite**
+
+Run:
+
+```bash
+rtk npm test
+```
+
+Expected: PASS.
+
+- [ ] **Step 3: Run production build**
+
+Run:
+
+```bash
+rtk npm run build
+```
+
+Expected: PASS.
+
+- [ ] **Step 4: Review git diff**
+
+Run:
+
+```bash
+rtk git diff -- src/App.vue src/App.test.ts docs/superpowers/plans/2026-06-16-frontend-routing.md
+```
+
+Expected: diff only contains routing implementation, routing tests, and this plan.
