docs(06-02): complete react architecture design plan 

Phase 6 Plan 2 complete - React architecture designed for Phases 7-11:

Summary:
- All 3 tasks completed successfully
- 3 design documents created (3,224 lines total)
- Component architecture, Redux state, and implementation roadmap ready
- Phase 6 complete, ready for Phase 7

Design Documents Created:
- CHAT_COMPONENT_DESIGN.md (954 lines): 8 components, WindowPortal integration, auto-scroll logic
- CHAT_REDUX_DESIGN.md (1,132 lines): sessionChatSlice, 3 async thunks, 8 selectors, WebSocket integration
- IMPLEMENTATION_ROADMAP.md (1,138 lines): 11-13 plans for Phases 7-11, risk analysis, TDD strategy

Key Architectural Decisions:
- Component hierarchy: JKSessionChatWindow (WindowPortal) with 6 sub-components
- Props vs Redux: Heavy Redux usage (minimal props)
- Auto-scroll: Track isUserScrolling, disable when scrolled up
- Multi-channel state: messagesByChannel keyed by channel ID
- Read/unread tracking: Client-side with localStorage (NEW functionality)
- Message deduplication: By msg_id in Redux reducer
- WebSocket integration: CHAT_MESSAGE handler in useSessionWebSocket

Redux Architecture:
- sessionChatSlice (new): 7 reducers, 3 async thunks, 8 memoized selectors
- Reducers: addMessageFromWebSocket, openChatWindow, markAsRead, etc.
- Thunks: fetchChatHistory, sendMessage, markMessagesAsRead (future)
- Selectors: selectChatMessages, selectUnreadCount, selectTotalUnreadCount, etc.

Implementation Roadmap (Phases 7-11):
- Phase 7: Chat Infrastructure (3 plans) - Redux, API, WebSocket

- Phase 9: Message Composition (2 plans) - Composer, Send/Receive
- Phase 10: Read/Unread Tracking (2 plans) - Badge, Channel Switching
- Phase 11: Finalization (3 plans) - Error Handling, Performance, UAT

Risk Analysis:
- 2 HIGH: WebSocket deduplication, localStorage persistence
- 4 MEDIUM: Auto-scroll, multi-tab sync, API errors, WindowPortal styling
- 2 LOW: Character count, timestamp formatting

TDD Strategy:
- Phase 7: 100% TDD (data layer)
- Phase 8-10: 50-100% TDD (behavior)
- Phase 11: 70% TDD (error handling)

# Phase 6 Plan 2: React Architecture & Implementation Roadmap Summary
**Designed React architecture, Redux state, and created implementation roadmap for Phases 7-11**
**Date:** 2026-01-26
**Status:** Complete
**Commits:** 192703f59, 3206c1268, df87713ff
---
## Accomplishments
### Task 1: Design Component Architecture ✅
**File Created:** `.planning/phases/06-session-chat-research-design/CHAT_COMPONENT_DESIGN.md` (954 lines)
**Component Hierarchy Designed:**
- **JKSessionChatButton** - Top nav button with unread badge
- **JKSessionChatWindow** - Main window wrapper (WindowPortal)
- **JKChatHeader** - Title bar with close button
- **JKChatMessageList** - Scrollable container with auto-scroll
- **JKChatMessage** - Single message (avatar, name, text, timestamp)
- **JKChatLoadingSpinner** - Loading indicator
- **JKChatEmptyState** - Empty state display
- **JKChatComposer** - Message input and send button
**Key Design Decisions:**
- **WindowPortal Integration:** Reuse existing component (no modifications needed)
- **Props vs Redux Matrix:** Heavy Redux usage (minimal props)
- **Auto-Scroll Logic:** Track `isUserScrolling` state, disable auto-scroll when user scrolls up
- **Enter-to-Send:** Enter sends, Shift+Enter adds newline
- **Component File Structure:** `jam-ui/src/components/client/chat/`
**Patterns Applied:**
- Follows JamTrack player architecture (main component + sub-components)
- Matches Backing Track patterns (WindowPortal, Redux-heavy)
- Component lifecycle: Mount → Fetch history → Mark as read → Unmount
---
### Task 2: Design Redux State and WebSocket Integration ✅
**File Created:** `.planning/phases/06-session-chat-research-design/CHAT_REDUX_DESIGN.md` (1,132 lines)
**Redux State Structure:**
- **sessionChatSlice** (new slice)
- `messagesByChannel`: Keyed by channel ID for efficient lookup
- `unreadCounts`: Per-channel unread tracking (NEW functionality)
- `lastReadAt`: Timestamps for read state (localStorage persistence)
- `fetchStatus` / `sendStatus`: Per-channel operation status
- `isWindowOpen`: Window state (UI)
**Async Thunks (3):**
1. **fetchChatHistory** - Load message history via REST API
2. **sendMessage** - Send new message with optimistic update
3. **markMessagesAsRead** - Mark as read (future server-side tracking)
**Reducers (7):**
1. **addMessageFromWebSocket** - Handle real-time messages, deduplicate by `msg_id`
2. **setActiveChannel** - Switch between global/session/lesson
3. **openChatWindow** - Reset unread count, mark as read
4. **closeChatWindow** - Close window state
5. **markAsRead** - Client-side read tracking with localStorage
6. **incrementUnreadCount** - Increment on message receive
7. **setWindowPosition** - Save window position
**Selectors (8 memoized with Reselect):**
- `selectChatMessages`, `selectUnreadCount`, `selectTotalUnreadCount`
- `selectIsChatWindowOpen`, `selectActiveChannel`
- `selectFetchStatus`, `selectSendStatus`, `selectSendError`
**WebSocket Integration:**
- **CHAT_MESSAGE Handler** in `useSessionWebSocket` hook
- Protocol Buffer to Redux format conversion
- Unread count increment logic (if window closed or different channel)
- Message deduplication by `msg_id`
**Read/Unread Tracking System (NEW):**
- **Client-side tracking** with localStorage persistence
- Store `lastReadAt` timestamp per channel
- Calculate unread count: messages with `createdAt > lastReadAt`
- Reset on window open or channel switch
- **Server-side tracking deferred** to future milestone (new API endpoint needed)
---

- Typing indicators
- Emoji picker
- Multi-channel tabs UI
- Notification sounds
- Desktop notifications
---
## Decisions Made
### 1. Component Architecture
**JKSessionChatWindow follows JamTrack pattern:**
- Main component wraps WindowPortal
- Sub-components for modularity (Header, MessageList, Message, Composer)
- Props vs Redux: Heavy Redux (minimal props, only callbacks)
**Auto-Scroll Logic:**
- Track `isUserScrolling` state
- Disable auto-scroll if user scrolls up
- Re-enable when user scrolls to bottom
- Matches legacy ChatWindow behavior
**WindowPortal for Modeless Dialog:**
- Reuse existing component (no modifications)
- 400x600px dimensions (similar to Metronome)
- User-repositionable (WindowPortal handles)
---
### 2. Redux State Architecture
**sessionChatSlice (New Slice):**
- Multi-channel storage: `messagesByChannel[channelId]`
- Efficient lookup by channel ID (no filtering needed)
- Unread counts per channel (NEW functionality)
- localStorage persistence for `lastReadAt` timestamps
**Message Deduplication:**
- Deduplicate by `msg_id` in `addMessageFromWebSocket` reducer
- Prevents duplicate UI rendering on WebSocket reconnect
- Unit tests for deduplication logic
**Async Thunk Pattern:**
- Follow existing patterns from mediaSlice (Phase 5)
- Error handling: pending/fulfilled/rejected states
- Extra reducers for state updates
---
### 3. Read/Unread Tracking Strategy
**Client-Side Tracking (Phase 6):**
- Store `lastReadAt` timestamp per channel in Redux
- Persist to localStorage for cross-session consistency
- Calculate unread count on message receive (if window closed)
- Reset on window open or channel switch
**Server-Side Tracking (Future):**
- Create new `chat_message_reads` table
- API endpoint: `PUT /api/chat/mark_read`
- Cross-device synchronization
- Per-message read receipts (optional)
**Rationale:**
- Client-side simpler for MVP
- Server-side more robust but requires schema changes
- Acceptable tradeoff: Unread counts reset on logout (MVP)
---
### 4. Multi-Channel Architecture
**Channel Keying:**
- Global: `'global'`
- Session: `'session-{sessionId}'`
- Lesson: `'lesson-{lessonId}'`
**Benefits:**
- Efficient lookups (no filtering)
- Supports multiple sessions (future: multi-session jam)
- Clean separation of global vs session messages
---
### 5. WebSocket Integration
**CHAT_MESSAGE Handler:**
- Add to existing `useSessionWebSocket` hook
- Convert Protocol Buffer format to Redux format
- Dispatch `addMessageFromWebSocket()` action
- Increment unread count if window closed
**No Modifications to JamServer:**
- `CHAT_MESSAGE` type already defined
- Use existing `registerMessageCallback` API
- Cleanup automatic (unregister on unmount)
---
### 6. TDD Approach
**100% TDD for Data Layer:**
- Redux reducers, async thunks, selectors
- API client methods
- WebSocket handlers
- Validation logic
**50-70% TDD for UI:**
- Component behavior (send, auto-scroll, unread badge)
- Keyboard handling
- Error handling
- Skip styling, visual appearance
**Rationale:**
- CLAUDE.md requires TDD for jam-ui
- Data layer has clear test criteria
- UI behavior has measurable outcomes
- Styling is visual, hard to test programmatically
---
## Files Created/Modified
**Created:**
- `.planning/phases/06-session-chat-research-design/CHAT_COMPONENT_DESIGN.md` (954 lines)
- `.planning/phases/06-session-chat-research-design/CHAT_REDUX_DESIGN.md` (1,132 lines)
- `.planning/phases/06-session-chat-research-design/IMPLEMENTATION_ROADMAP.md` (1,138 lines)
**Total:** 3,224 lines of documentation
**Commits:**
- `192703f59` - feat(06-02): design session chat component architecture
- `3206c1268` - feat(06-02): design Redux state and WebSocket integration for chat
- `df87713ff` - feat(06-02): create implementation roadmap for Phases 7-11
---
## Key Insights
### 1. Chat is Simpler Than JamTrack
**No Native Client Integration:**
- Chat is purely web-based (REST API + WebSocket)
- JamTrack uses jamClient.* methods (complex download/sync)
- Chat state machine simpler (3 states vs 6-state machine)
**Implication:** Phase 7-11 should be faster than Phase 5 (JamTrack)
---
### 2. Read/Unread Tracking is NEW
**Critical Finding:** Session/global chat has NO persistent tracking in legacy.
**Design from Scratch:**
- No legacy patterns to follow
- Must align with lesson chat patterns (teacher_unread_messages, student_unread_messages)
- Client-side tracking acceptable for MVP
- Server-side tracking deferred to next milestone
**Implication:** This is NEW functionality, not just porting legacy
---
### 3. WindowPortal is Proven Pattern
**Already Used By:**
- Metronome popup (Phase 2)
- JamTrack player popup (Phase 5)
**Benefits:**
- No modifications needed (reuse as-is)
- Auto-handles styling, cleanup, lifecycle
- User-repositionable, modeless dialog
**Implication:** Phase 8 should be straightforward (no WindowPortal debugging)
---
### 4. Multi-Channel Complexity
**Legacy Pattern:**
- Single store manages all channels (global, session, lesson_N)
- Active channel tracked in state
- Messages keyed by channel ID
**Design Decision:**
- Follow legacy pattern (proven to work)
- `messagesByChannel[channelId]` for efficient lookup
- Avoid filtering on every render
**Implication:** Slightly more complex than single-channel, but more scalable
---
### 5. TDD Methodology Required
**CLAUDE.md Mandate:**
- All jam-ui code changes MUST follow TDD
- Test-first for data layer
- Test component behavior (not appearance)
**Phase 7-11 Strategy:**
- Phase 7: 100% TDD (foundation)
- Phase 8-10: Mixed TDD (behavior, skip styling)
- Phase 11: 70% TDD (error handling, skip performance)
**Implication:** Testing effort is significant (~30-40% of implementation time)
---
## Issues Encountered
