+# AIUI Project Plan: Roadmap, Progress Tracking & Automated Coding Tasks
+
+## Context
+
+AIUI is at ~65% architectural completeness. The chat + content surface experience is mature (11 content types, streaming, responsive layout, glass morphism design system). However, critical infrastructure is missing: no persistent storage beyond dev mode, zero error boundaries, no unit tests, plugin system spec'd but unused, no encryption.
+
+The user has Claude Code automation set up for late-night unattended runs. This plan provides:
+1. **Progress tracking automation** — PROGRESS.md updated on every commit/push
+2. **Detailed task specs** — granular enough for automated Claude sessions to execute autonomously
+
+There are **6 active worktrees** — all automation must work across branches.
+
+---
+
+## Part 1: Progress Tracking Automation
+
+### Task 1.1: Create PROGRESS.md
+
+**File**: `PROGRESS.md` (repo root)
+
+Create a structured progress document with:
+- Project status summary (current milestone, % complete)
+- Roadmap checklist (M0–M7, matching Part 2 below)
+- Session log section (auto-populated by hook)
+
+Format:
+```markdown
+# AIUI Progress
+
+## Current Status
+**Active Milestone**: M1 — Stability & Polish
+**Overall**: ~65% architectural completeness
+
+## Roadmap
+### M0: Foundation ✅
+- [x] Chat interface with streaming
+- [x] 11 content type renderers
+- [x] Responsive layout (mobile + desktop)
+- [x] Glass morphism design system
+- [x] Claude proxy + web search
+- [x] PWA support
+
+### M1: Stability & Polish 🔄
+- [ ] Persistent storage (IndexedDB)
+- [ ] Error boundaries
+- [ ] Unit tests for composables
+- [ ] E2E test coverage
+- [ ] CI pipeline
+
+(... remaining milestones from Part 2 ...)
+
+## Session Log
+<!-- Auto-populated by post-push hook -->
+```
+
+### Task 1.2: Create post-push progress hook
+
+**File**: `.claude/hooks/post-push-progress.sh`
+
+A `PostToolUse` hook for Bash that:
+1. Reads stdin JSON, extracts `tool_input.command`
+2. Checks if command contains `git push` or `git commit`
+3. If match: runs `git log --oneline` for commits on current branch not on `main`
+4. Reads current PROGRESS.md roadmap section to identify active milestone
+5. Outputs JSON with `hookSpecificOutput` containing a message asking Claude to update the Session Log in PROGRESS.md
+
+The hook script should:
+- Extract branch name via `git branch --show-current`
+- Get commit list via `git log --oneline main..HEAD` (or last 5 commits if no divergence)
+- Format the output as structured feedback
+
+### Task 1.3: Register the hook
+
+**File**: `.claude/settings.json`
+
+Add a PostToolUse entry:
+```json
+{
+  "hooks": {
+    "PreToolUse": [ ... existing ... ],
+    "PostToolUse": [
+      {
+        "matcher": "Bash",
+        "hooks": [
+          {
+            "type": "command",
+            "command": "\"$CLAUDE_PROJECT_DIR\"/.claude/hooks/post-push-progress.sh"
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+---
+
+## Part 2: Long-Term Delivery Roadmap
+
+### M0: Foundation ✅ (Complete)
+All done — chat, renderers, layout, design system, proxy, PWA.
+
+---
+
+### M1: Stability & Polish (Infrastructure)
+
+#### Task M1.1: IndexedDB Persistent Storage
+
+**Why**: Conversations are lost on page refresh in production. Currently only persisted via dev-mode `/api/dev-chats` Vite middleware.
+
+**Files to modify**:
+- `packages/app/src/stores/chat.ts` (198 lines) — add IndexedDB adapter
+- Create `packages/app/src/utils/idb-storage.ts` — IndexedDB wrapper
+
+**Implementation**:
+1. Create `idb-storage.ts` with these functions:
+   ```ts
+   export async function openDB(): Promise<IDBDatabase>
+   export async function saveConversation(conv: Conversation): Promise<void>
+   export async function loadAllConversations(): Promise<Map<string, Conversation>>
+   export async function deleteConversation(id: string): Promise<void>
+   ```
+   - DB name: `aiui-store`, version 1
+   - Object store: `conversations`, keyPath: `id`
+   - Index on `updatedAt` for sorted retrieval
+
+2. Modify `chat.ts`:
+   - Replace `saveServerChats()` (line 51-62) with `saveConversation()` calls
+   - Replace `loadServerChats()` (line 64-84) with `loadAllConversations()`
+   - Keep dev-chats middleware as fallback when `indexedDB` unavailable
+   - Debounced save stays at 800ms
+
+**Acceptance criteria**:
+- Conversations survive page refresh
+- New conversations appear after reload
+- Delete removes from IndexedDB
+- Falls back to dev-chats middleware if IDB unavailable
+- `pnpm typecheck` passes
+
+#### Task M1.2: Error Boundaries
+
+**Why**: Zero `onErrorCaptured` usage. Any component error crashes the whole app.
+
+**Files to modify**:
+- Create `packages/app/src/components/ui/ErrorBoundary.vue`
+- `packages/app/src/pages/ChatPage.vue` (597 lines) — wrap major sections
+- `packages/app/src/components/chat/ChatWindow.vue` (248 lines) — wrap message list
+- `packages/app/src/components/content/ContentPanel.vue` — wrap detail views
+
+**Implementation**:
+1. Create `ErrorBoundary.vue`:
+   ```vue
+   <script setup lang="ts">
+   import { ref, onErrorCaptured } from 'vue'
+   defineProps<{ fallbackMessage?: string }>()
+   const error = ref<Error | null>(null)
+   const hasError = ref(false)
+   onErrorCaptured((err) => {
+     error.value = err instanceof Error ? err : new Error(String(err))
+     hasError.value = true
+     return false // prevent propagation
+   })
+   function retry() { hasError.value = false; error.value = null }
+   </script>
+   <template>
+     <slot v-if="!hasError" />
+     <div v-else class="glass-card p-4 text-center">
+       <p class="text-white/60">{{ fallbackMessage || 'Something went wrong' }}</p>
+       <button class="glass-button-sm mt-2" @click="retry">Retry</button>
+     </div>
+   </template>
+   ```
+
+2. Wrap in ChatPage.vue:
+   - Wrap chat column (around `<ChatWindow>`)
+   - Wrap content panel column (around `<ContentPanel>`)
+   - Wrap detail view column (around `<DetailView>`)
+
+3. Wrap in ChatWindow.vue:
+   - Wrap the message loop (v-for of ChatMessage)
+
+4. Wrap in ContentPanel.vue:
+   - Wrap each grid component render
+   - Wrap detail component render
+
+**Acceptance criteria**:
+- A failing renderer shows error card with retry button
+- Chat continues working if content panel errors
+- Content panel continues if one card errors
+- `pnpm typecheck` passes
+
+#### Task M1.3: Unit Tests for contentExtraction
+
+**Why**: `contentExtraction.ts` is 967 lines of regex parsing with zero tests. It's the most critical composable.
+
+**File to create**: `packages/app/src/__tests__/contentExtraction.test.ts`
+
+**Tests to write** (use vitest):
+```ts
+describe('contentExtraction', () => {
+  describe('extractAllFilms', () => {
+    it('extracts film_ext tags with title, year, director')
+    it('extracts film:id tags and looks up from library')
+    it('returns empty array for text with no film tags')
+    it('handles multiple films in one message')
+    it('handles malformed tags gracefully')
+  })
+
+  describe('extractAllSongs', () => {
+    it('extracts song_ext tags with title, artist, year')
+    it('extracts song:id tags from library')
+    it('extracts songs from markdown bold patterns')
+    it('deduplicates songs by title+artist')
+  })
+
+  describe('extractAllPodcasts', () => {
+    it('extracts podcast_ext tags')
+    it('extracts podcast:id from library')
+  })
+
+  describe('extractAllBooks', () => {
+    it('extracts book_ext tags with title, author, year')
+    it('handles optional fields')
+  })
+
+  describe('extractAllTVSeries', () => {
+    it('extracts tv_ext tags')
+    it('parses creator and network fields')
+  })
+
+  describe('extractAllPlaces', () => {
+    it('extracts place_ext tags with all fields')
+    it('handles missing optional fields (rating, price)')
+  })
+
+  describe('extractMagazineSections', () => {
+    it('extracts sections from markdown headings')
+    it('captures content between headings')
+    it('extracts hero images')
+  })
+
+  describe('stripContentTags', () => {
+    it('removes all tag types from text')
+    it('preserves non-tag content')
+    it('handles nested/adjacent tags')
+  })
+
+  describe('extractBoldDomainLinks', () => {
+    it('extracts **domain.com** patterns with URLs')
+    it('extracts markdown links')
+  })
+})
+```
+
+**How to run**: `pnpm test` (vitest via turbo)
+
+**Acceptance criteria**:
+- All tests pass
+- Covers the 10 main extraction functions
+- Tests edge cases (empty input, malformed tags, duplicates)
+- `pnpm test` exits 0
+
+#### Task M1.4: Unit Tests for useAI
+
+**File to create**: `packages/app/src/__tests__/useAI.test.ts`
+
+**Tests to write**:
+```ts
+describe('useAI', () => {
+  describe('provider selection', () => {
+    it('defaults to first available provider')
+    it('switches provider via setActiveProvider')
+    it('lists available models for active provider')
+  })
+
+  describe('context injection', () => {
+    it('includes film library in system prompt')
+    it('includes song library in system prompt')
+    it('includes content tag format instructions')
+  })
+
+  describe('sendMessage', () => {
+    it('adds user message to store')
+    it('creates assistant message placeholder')
+    it('sets isStreaming to true during stream')
+    it('sets isStreaming to false after completion')
+    it('handles stream errors gracefully')
+  })
+
+  describe('stopGeneration', () => {
+    it('aborts active stream')
+    it('sets isStreaming to false')
+  })
+})
+```
+
+**Note**: Will need to mock `fetch` for streaming tests. Use vitest's `vi.fn()`.
+
+**Acceptance criteria**:
+- All tests pass with mocked fetch/SSE
+- `pnpm test` exits 0
+
+#### Task M1.5: E2E Test Expansion
+
+**File to modify**: `packages/app/e2e/content-surfaces.spec.ts`
+
+**Tests to add**:
+```ts
+test('sends a message and receives streaming response')
+test('content panel shows film cards when AI mentions films')
+test('clicking a film card opens detail view')
+test('mobile viewport shows full-screen overlay for content')
+test('stop button halts generation')
+test('web search toggle works')
+test('new conversation clears messages')
+test('panel side toggle switches layout')
+```
+
+**Acceptance criteria**:
+- `pnpm test:e2e` passes (needs dev server running)
+
+---
+
+### M2: Content Experience (UX)
+
+#### Task M2.1: Markdown Rendering in Chat
+
+**Why**: Chat messages display plain text. Markdown (bold, italic, links, code blocks, lists) should render properly.
+
+**Files to modify**:
+- `packages/app/src/components/chat/ChatMessage.vue` (333 lines)
+- Add `markdown-it` as dependency
+
+**Implementation**:
+1. `pnpm add markdown-it` + `pnpm add -D @types/markdown-it` in `packages/app`
+2. In ChatMessage.vue:
+   - Import and configure markdown-it with safe defaults (no HTML)
+   - After `stripContentTags()`, render remaining text through markdown-it
+   - Use `v-html` with the sanitized markdown output
+   - Add CSS for rendered markdown (code blocks, lists, links) in main.css
+   - Ensure content tags are extracted BEFORE markdown rendering
+
+**Security**: markdown-it with `html: false` prevents XSS. No raw HTML passthrough.
+
+**Acceptance criteria**:
+- Bold, italic, links, code blocks, lists render in chat
+- Content tags still extract correctly (films, songs, etc.)
+- No XSS possible
+- `pnpm typecheck` passes
+
+#### Task M2.2: Virtual Scrolling for Chat
+
+**Why**: Long conversations with many messages cause scroll jank.
+
+**Files to modify**:
+- `packages/app/src/components/chat/ChatWindow.vue`
+- Add `@tanstack/vue-virtual` dependency
+
+**Implementation**:
+1. `pnpm add @tanstack/vue-virtual` in `packages/app`
+2. Replace the message `v-for` loop with `useVirtualizer`:
+   - Estimate row heights (user messages ~60px, assistant ~200px)
+   - Use dynamic measurement for actual heights
+   - Maintain scroll-to-bottom behavior during streaming
+   - Keep overscan at 5 items
+
+**Acceptance criteria**:
+- Scrolling is smooth with 100+ messages
+- Auto-scroll to bottom during streaming still works
+- `pnpm typecheck` passes
+
+#### Task M2.3: Music Source Resolution
+
+**Why**: PlayerBar exists but music source resolution is incomplete. Iframe embedding untested.
+
+**Files to modify**:
+- `packages/app/src/composables/usePlayer.ts` (185 lines)
+- `packages/app/src/components/player/PlayerBar.vue` (165 lines)
+
+**Implementation**:
+1. In usePlayer.ts:
+   - Add queue management: `queue: ShallowRef<Song[]>`, `currentIndex: Ref<number>`
+   - Add `playNext()`, `playPrevious()`, `addToQueue(song)` methods
+   - Fix iframe playback (lines 72-83): create Plyr instance for iframes too
+   - Add retry logic for failed music searches (try next source)
+
+2. In PlayerBar.vue:
+   - Add next/previous buttons
+   - Show queue count
+   - Add queue panel (slide-up from player)
+
+**Acceptance criteria**:
+- Can play songs from search results
+- Next/previous navigation works
+- Queue persists across song changes
+- `pnpm typecheck` passes
+
+#### Task M2.4: Nostr Feed Integration
+
+**Why**: NostrGrid.vue exists but is non-functional. No relay connection.
+
+**Files to modify**:
+- `packages/app/src/components/content/NostrGrid.vue`
+- Create `packages/app/src/composables/useNostr.ts`
+
+**Implementation**:
+1. Create `useNostr.ts`:
+   - Connect to public relays (wss://relay.damus.io, wss://nos.lol, wss://relay.snort.social)
+   - Use raw WebSocket (no nostr-tools dependency to keep bundle small)
+   - Subscribe to kind:1 (text notes) with limit 50
+   - Parse NIP-01 event format manually
+   - Export `useNostr()` returning `{ events, isConnected, connect, disconnect }`
+
+2. Update NostrGrid.vue:
+   - Use `useNostr()` composable
+   - Display events as cards with author npub (truncated), content, timestamp
+   - Lazy-load on tab activation only
+
+**Acceptance criteria**:
+- Nostr tab shows real posts from public relays
+- Connection/disconnection is clean (no leaked WebSockets)
+- Handles relay errors gracefully
+- `pnpm typecheck` passes

+
+### M3: Plugin System (Infrastructure)
+
+#### Task M3.1: Activate Plugin Registry at Runtime
+
+**Why**: `packages/core/src/plugins/registry.ts` exists with `registerPlugin()` but nothing calls it.
+
+**Files to modify**:
+- `packages/app/src/main.ts` (26 lines) — add plugin initialization
+- Create `packages/app/src/plugins/index.ts` — plugin bootstrap
+- Create `packages/app/src/plugins/claude-provider.ts` — first AI provider plugin
+
+**Implementation**:
+1. Create `plugins/index.ts`:
+   ```ts
+   export async function initializePlugins() {
+     // Register built-in plugins
+     const { claudeProvider } = await import('./claude-provider')
+     registerPlugin(claudeProvider)
+   }
+   ```
+
+2. Create `plugins/claude-provider.ts`:
+   - Implement `AIProviderAdapter` interface from `@aiui/core`
+   - Wrap existing `useAI.ts` streaming logic as a plugin
+   - Export as a Tier 1 (trusted) plugin
+
+3. In `main.ts`:
+   - Call `initializePlugins()` before app mount
+   - Make it async with error handling
+
+**Acceptance criteria**:
+- Plugin registry has at least 1 registered plugin at runtime
+- Chat still works through the plugin adapter
+- `getPluginsByType('ai-provider')` returns the Claude provider
+- `pnpm typecheck` passes
+
+#### Task M3.2: Renderer Plugin Registration
+
+**Why**: Content renderers are hardcoded. Making them pluggable enables community extensions.
+
+**Files to modify**:
+- Create `packages/app/src/plugins/renderers/film-renderer.ts`
+- Create `packages/app/src/plugins/renderers/song-renderer.ts`
+- Modify `packages/app/src/plugins/index.ts` — register renderers
+- Modify `packages/app/src/components/content/ContentPanel.vue` — use registry lookups
+
+**Implementation**:
+1. Create renderer plugins for film and song (as examples):
+   ```ts
+   const filmRenderer: RendererDefinition = {
+     id: 'film',
+     name: 'Film Renderer',
+     contentType: 'film',
+     surfaces: ['chat-preview', 'panel-preview', 'panel-play'],
+     chatPreview: FilmCard,
+     panelPreview: FilmGrid,
+     panelPlay: FilmDetail,
+   }
+   ```
+
+2. Register in `plugins/index.ts` via `registerRenderer()`
+
+3. In ContentPanel.vue, look up renderers via `getRendererForContentType()` instead of hardcoded imports (gradual migration — start with film/song, keep others hardcoded)
+
+**Acceptance criteria**:
+- Film and song renderers registered via plugin system
+- `getAllRenderers()` returns registered renderers
+- Content panel still renders correctly
+- `pnpm typecheck` passes

+## Part 3: Automated Session Execution Order
+
+For automated late-night Claude sessions, execute tasks in this order:
+
+### Priority Queue (each session picks next incomplete task):
+
+1. **Task 1.1** — Create PROGRESS.md *(5 min)*
+2. **Task 1.2** — Create post-push progress hook *(10 min)*
+3. **Task 1.3** — Register hook in settings.json *(2 min)*
+4. **Task M1.2** — Error boundaries *(15 min)*
+5. **Task M1.3** — Unit tests for contentExtraction *(20 min)*
+6. **Task M1.1** — IndexedDB persistent storage *(25 min)*
+7. **Task M1.4** — Unit tests for useAI *(20 min)*
+8. **Task M2.1** — Markdown rendering *(20 min)*
+9. **Task M1.5** — E2E test expansion *(15 min)*
+10. **Task M2.3** — Music source resolution *(20 min)*
+11. **Task M2.2** — Virtual scrolling *(15 min)*
+12. **Task M2.4** — Nostr feed integration *(25 min)*
+13. **Task M3.1** — Activate plugin registry *(20 min)*
+14. **Task M3.2** — Renderer plugin registration *(20 min)*
+
+### Session Protocol
+
+Each automated session should:
+1. Read `PROGRESS.md` to find the next incomplete task
+2. Read this plan file for the task's detailed spec
+3. Execute the task following the spec exactly
+4. Run `pnpm typecheck` after changes
+5. Run `pnpm lint` after changes
+6. Run `pnpm test` if unit tests exist
+7. Commit with conventional format: `type(scope): description`
+8. Push to current branch
+9. Update PROGRESS.md session log (triggered by hook, or manually)
+
+---
+
+## Verification
+
+After implementing Part 1 (progress automation):
+1. Run `pnpm typecheck && pnpm lint` — should pass
+2. Commit a change and push — hook should fire
+3. Verify PROGRESS.md gets a session log entry
+4. Test from a different worktree — should work identically
+
+After each M1–M3 task:
+1. `pnpm typecheck` passes
+2. `pnpm lint` passes
+3. `pnpm test` passes (if tests exist)
+4. Dev server runs without errors (`pnpm dev`)
+5. Manual smoke test: send a message, see content render
