+**Objective:** Analyze repository issues and provide actionable fix comments
+
+---
+
+## π Analysis Results
+
+### Issues Analyzed: 1
+
+#### Issue #2: "No Move History"
+- **Status:** β
Analyzed and Documented
+- **Root Cause:** DOM Element ID mismatch in `js/main.js:185`
+- **Severity:** Medium (High user impact, trivial fix)
+- **Fix Complexity:** 1-line code change
+- **Analysis Document:** `docs/issue-2-analysis.md`
+- **Comment Posted:** β

+**Problem:** The move history UI component is not displaying moves.
+
+**Root Cause:** JavaScript code references wrong DOM element ID:
+- **Expected:** `move-history` (as defined in `index.html:43`)
+- **Actual:** `move-list` (as referenced in `js/main.js:185`)
+
+**Fix:** Change line 185 in `js/main.js` from:
+```javascript
+const moveList = document.getElementById('move-list');
+```
+to:
+```javascript
+const moveList = document.getElementById('move-history');

+
+### Issues Analyzed: 2 New Issues
+
+#### Issue #3: "No Captures"
+- **Status:** β
Analyzed and Documented
+- **Type:** Bug (DOM Element ID Mismatch)
+- **Root Cause:** JavaScript references `'white-captured'` and `'black-captured'` but HTML uses `'captured-white-pieces'` and `'captured-black-pieces'`
+- **Location:** `js/main.js:214-215`

+#### Issue #4: "AI Opponent"
+- **Status:** β
Analyzed and Documented
+- **Type:** Feature Request (New Development)
+- **Requirement:** Implement AI opponent for single-player mode
+- **Current State:** No AI implementation exists
+- **Recommended Approach:** Minimax algorithm (16-24 hours) or Library integration (8-12 hours)
+- **Complexity:** Medium-High
+- **Effort Estimate:** 33-47 hours (full minimax) or 8-12 hours (Stockfish.js)
+- **Analysis Document:** `docs/issue-4-analysis.md`
+- **Comment Posted:** β
Yes

+
+## π Analysis Summary
+
+### Issue #3: No Captures (Bug Fix)
+
+**Root Cause:**
+DOM element ID mismatch in `js/main.js:214-215`
+
+**Expected IDs:** `'captured-white-pieces'`, `'captured-black-pieces'`
+**Actual References:** `'white-captured'`, `'black-captured'`
+
+**Fix Required:**
+```javascript
+// BEFORE (Lines 214-215)
+const whiteCaptured = document.getElementById('white-captured');
+const blackCaptured = document.getElementById('black-captured');
+
+// AFTER
+const whiteCaptured = document.getElementById('captured-white-pieces');
+const blackCaptured = document.getElementById('captured-black-pieces');
+```
+
+**Pattern Recognition:**
+This is the **third DOM ID mismatch** in the codebase:
+1. Issue #2: `'move-list'` vs `'move-history'`
+2. Issue #3: `'white-captured'` vs `'captured-white-pieces'`
+3. Issue #3: `'black-captured'` vs `'captured-black-pieces'`
+
+**Recommendation:** Create a DOM constants file to prevent future mismatches.
+
+---
+
+### Issue #4: AI Opponent (Feature Request)
+
+**Request:** Enable single-player mode with AI opponent
+
+**Current State:**
+- No AI implementation exists
+- No move evaluation logic
+- No search algorithms
+- Game requires manual moves for both sides
+
+**Implementation Options:**
+
+| Option | Effort | Strength | Complexity |
+|--------|--------|----------|------------|
+| 1. Random AI | 4-8h | Very Weak | Easy |
+| 2. Minimax | 16-24h | Decent (1200-1600 ELO) | Medium |
+| 3. Alpha-Beta | 40-60h | Strong (1600-2000+ ELO) | Advanced |
+| 4. Stockfish.js | 8-12h | Excellent (2500+ ELO) | Easy-Medium |
+
+**Recommended:** Option 2 (Minimax) for learning/control, or Option 4 (Stockfish.js) for fastest implementation
+
+**Required Components:**
+```
+js/ai/
+βββ ChessAI.js // Main controller
+βββ MoveEvaluator.js // Position evaluation
+βββ SearchAlgorithm.js // Minimax/Alpha-beta
+βββ AIPlayer.js // Player interface
+```
+
+**Key Features Needed:**
+- Position evaluation function (material, position, mobility, king safety)
+- Minimax search algorithm with configurable depth
+- Game mode selector (PvP vs PvAI)
+- Difficulty settings
+- "AI thinking" indicator
+- Integration with existing GameController

+
+## π― Key Recommendations
+
+### **Migration Strategy: Incremental (Recommended)**
+- β
Lower risk than big-bang approach
+- β
Game stays functional throughout
+- β
Easier to rollback individual modules
+- β
Team learns TypeScript gradually
+- β
Industry best practice for codebases >1,000 LOC
+
+### **Timeline: 6 Weeks (Balanced)**
+- 15-20 hours per week
+- Sustainable pace
+- Time for code review and learning
+- Handles unexpected issues
+- Alternative timelines: 4 weeks (aggressive), 8-10 weeks (conservative)
+
+### **Migration Phases (7 phases)**
+1. **Phase 0:** Foundation & Setup (4-6h)
+2. **Phase 1:** Core Types (6-8h)
+3. **Phase 2:** Game Models (8-10h) β οΈ CRITICAL PATH
+4. **Phase 3:** Piece Classes (8-10h)
+5. **Phase 4:** Game Engine (8-10h) β οΈ CRITICAL PATH
+6. **Phase 5:** Controllers & Views (6-8h)
+7. **Phase 6:** Integration & Testing (4-6h)
+
+**Total Effort:** 40-54 hours baseline, 70 hours with 50% contingency
+
+---
+
+## π‘ Key Architectural Decisions
+
+1. **Strict TypeScript Mode** - Maximum type safety from day 1
+2. **Bottom-Up Migration** - Dependencies first (utilities β models β engine β UI)
+3. **45+ Type Definitions** - Comprehensive type system across 5 type files
+4. **Type-Safe Events** - Generic event bus with discriminated unions
+5. **Path Aliases** - Clean imports (@game, @pieces, @engine, etc.)
+6. **Jest + ts-jest** - Maintain 100% test pass rate throughout
+7. **Quality Gates** - Tests, type check, coverage on every PR
+
+---
+
+## π Type System Overview
+
+The architecture defines **45+ interfaces and types**, including:
+
+**Core Types:**
+- Position, Color, Square, BoardGrid
+- PieceType enum with 6 piece types
+- IPiece, IBoard interfaces
+
+**Move System:**
+- Move interface with special move variants
+- SpecialMove enum (castle, en passant, promotion)
+- MoveResult with validation
+
+**Game State:**
+- GameStatus enum
+- GameConfig with time control
+- Type-safe game events
+
+**UI Types:**
+- GameEvent system with typed payloads
+- Event handlers with generics
+- DOM element types with null safety
+
+---
+
+## π§ͺ Testing Strategy
+
+**Current State:**
+- 124 Jest tests (all passing)
+- ~80% code coverage
+- Jest + jsdom + custom matchers
+
+**Migration Approach:**
+- Use ts-jest for TypeScript testing
+- Migrate tests incrementally (keep in .js initially)
+- Type-safe test factories and mocks
+- Maintain 100% pass rate throughout
+
+**Quality Gates (Every PR):**
+```bash
+β Tests Pass (100%)
+β Type Check (0 errors)
+β Type Coverage (β₯ 95%)
+β Code Coverage (β₯ 80%)
+β ESLint (0 errors)
+```
+
+---
+
+## β οΈ Risk Assessment
+
+### **Top 5 Risks Identified:**
+
+1. **Event System Migration** (HIGH)
+ - Complex generic type system needed
+ - Mitigation: Start simple, add complexity gradually
+
+2. **DOM Type Safety** (MEDIUM-HIGH)
+ - Extensive DOM manipulation
+ - Mitigation: Type guards, proper HTMLElement typing
+
+3. **Test Suite Compatibility** (MEDIUM)
+ - Jest + TypeScript + ESM configuration
+ - Mitigation: Use ts-jest, follow established patterns
+

+## π€ Hive Mind Analysis - Issue #2: No Move History
+
+**Analysis Date:** 2025-11-23
+**Analyzed By:** Hive Mind Collective Intelligence System
+**Status:** β
Root Cause Identified
+
+---
+
+### π― Issue Summary
+
+The move history panel in the chess application's UI is not displaying moves, despite the game state correctly tracking them internally.
+
+---
+
+### π Root Cause Analysis
+
+**File:** `js/main.js`
+**Location:** Line 185
+**Problem Type:** DOM Element ID Mismatch
+
+**The Bug:**
+```javascript
+// Line 185 in js/main.js
+const moveList = document.getElementById('move-list');
+```
+
+**Expected Element ID (from index.html:43):**
+```html
+
+```
+
+**Discrepancy:** The JavaScript code references `'move-list'` but the HTML element has ID `'move-history'`.
+
+---
+
+### β
Verified System Components
+
+**Working Correctly:**
+1. β
**GameState.js** (lines 8, 22-47): `moveHistory` array properly initialized and populated
+2. β
**GameController.js** (line 138): Moves correctly recorded via `recordMove(move)`
+3. β
**Move notation generation** (lines 154-190): Algebraic notation properly generated
+4. β
**Display update trigger** (line 165): `updateMoveHistory()` called on move events
+
+**The Issue:**
+- β **main.js:185**: References wrong DOM element ID (`'move-list'` instead of `'move-history'`)
+
+---
+
+### π οΈ Fix Implementation
+
+**Solution:** Update the element ID reference in `js/main.js:185`
+
+**Change Required:**
+```javascript
+// BEFORE (Line 185)
+const moveList = document.getElementById('move-list');
+
+// AFTER
+const moveList = document.getElementById('move-history');
+```
+
+**Alternative Fix:** If preferred, update `index.html:43` to use `id="move-list"` instead, but changing JavaScript is recommended to match existing HTML structure.
+
+---
+
+### π Implementation Steps
+
+1. **Open file:** `js/main.js`
+2. **Navigate to:** Line 185 (inside `updateMoveHistory()` method)
+3. **Replace:** `'move-list'` with `'move-history'`
+4. **Test:** Play a few moves and verify history displays correctly
+5. **Additional validation:** Check browser console for any DOM-related errors
+
+---
+
+### π§ͺ Testing Checklist
+
+After fix implementation:
+- [ ] Make several moves on the chess board
+- [ ] Verify moves appear in the right sidebar under "Move History"
+- [ ] Verify move notation format (e.g., "1. e4 e5")
+- [ ] Test undo/redo functionality with move history
+- [ ] Verify scroll behavior (auto-scroll to latest move)
+- [ ] Check empty state message: "No moves yet"
+- [ ] Verify move history persists during game
+
+---
+
+### π Impact Assessment
+
+**Severity:** Medium
+**User Impact:** High (core feature not working)
+**Fix Complexity:** Trivial (1-line change)
+**Testing Required:** Basic UI testing
+**Regression Risk:** None

+**Analyzed By:** Hive Mind Collective Intelligence System
+**Status:** β
Root Cause Identified
+
+---
+
+### π― Issue Summary
+
+Captured pieces are not displayed in the UI sidebars, despite the game state correctly tracking captured pieces internally.
+
+---
+
+### π Root Cause Analysis
+
+**File:** `js/main.js`
+**Location:** Lines 214-215
+**Problem Type:** DOM Element ID Mismatch
+
+**The Bug:**
+```javascript
+// Lines 214-215 in js/main.js
+const whiteCaptured = document.getElementById('white-captured');

+
+---
+
+### β
Verified System Components
+
+**Working Correctly:**
+1. β
**GameState.js** (line 9): `capturedPieces` object properly initialized
+2. β
**GameState.js** (lines 43-46): Captured pieces correctly added to arrays when pieces are captured

+---
+
+### π οΈ Fix Implementation
+
+**Solution:** Update the element ID references in `js/main.js:214-215`
+
+**Changes Required:**

+const blackCaptured = document.getElementById('captured-black-pieces');
+```
+
+**Alternative Fix:** Update `index.html` to use `id="white-captured"` and `id="black-captured"`, but changing JavaScript is recommended to maintain consistency with existing naming pattern (`captured-{color}-pieces`).

+### π Impact Assessment
+
+**Severity:** Medium
+**User Impact:** High (core feature not working)
+**Fix Complexity:** Trivial (2-line change)
+**Testing Required:** Basic UI testing
+**Regression Risk:** None
+**Related Issues:** Issue #2 (same pattern - DOM ID mismatch)
+
+---
+
+### π Related Code References
+
+- **HTML Elements:** `index.html:31, 55`
+- **JavaScript Bug:** `js/main.js:214-215`
+- **State Management:** `js/game/GameState.js:9, 43-46, 74, 98`
+- **Display Update:** `js/main.js:168, 213-226`
+- **CSS Styling:** `css/main.css:79-86`, `css/pieces.css:59`
+
+---
+
+### π‘ Additional Recommendations
+
+1. **Code Review:** Systematically check all `getElementById()` calls against HTML element IDs
+2. **Constants File:** Create a constants file for DOM element IDs:
+ ```javascript
+ // js/utils/DOMConstants.js
+ export const DOM_IDS = {
+ MOVE_HISTORY: 'move-history',
+ CAPTURED_WHITE_PIECES: 'captured-white-pieces',
+ CAPTURED_BLACK_PIECES: 'captured-black-pieces',
+ // ... other IDs
+ };
+ ```
+
+3. **Error Handling:** Add null checks after DOM queries:
+ ```javascript
+ const whiteCaptured = document.getElementById('captured-white-pieces');
+ if (!whiteCaptured) {
+ console.error('Captured white pieces element not found');
+ return;
+ }
+ ```
+
+4. **Testing:** Add automated UI tests to catch missing DOM elements early
+
+5. **Pattern Detection:** Both Issue #2 and Issue #3 are DOM ID mismatches - consider a pre-deployment checklist to verify all DOM references
+
+---
+
+### π Relationship to Other Issues
+
+**Issue #2 (No Move History):** Same root cause pattern - DOM element ID mismatch
+- Issue #2: `'move-list'` vs `'move-history'`
+- Issue #3: `'white-captured'` vs `'captured-white-pieces'`
+
+Both issues suggest a need for better DOM element ID management and testing.

+βββ ai/ β DOES NOT EXIST - needs creation
+```
+
+---
+
+### ποΈ Implementation Approaches
+
+#### **Option 1: Random Move AI (Quick Implementation)**
+
+**Difficulty:** Easy
+**Effort:** 4-8 hours
+**Playing Strength:** Very weak
+
+**Implementation:**
+```javascript
+class RandomAI {
+ getBestMove(board, gameState, color) {
+ const legalMoves = this.getAllLegalMoves(board, color);
+ const randomIndex = Math.floor(Math.random() * legalMoves.length);
+ return legalMoves[randomIndex];
+ }
+}
+```
+
+**Pros:**
+- Very simple to implement
+- Good for initial testing
+- No performance concerns
+
+**Cons:**
+- Terrible playing strength
+- Not engaging for users
+- No strategic thinking
+
+---
+
+#### **Option 2: Minimax Algorithm (Recommended)**
+
+**Difficulty:** Medium
+**Effort:** 16-24 hours
+**Playing Strength:** Decent (1200-1600 ELO)
+
+**Core Algorithm:**
+```javascript
+class MinimaxAI {
+ minimax(board, depth, maximizing) {
+ if (depth === 0) {
+ return this.evaluatePosition(board);
+ }
+
+ const moves = this.getAllLegalMoves(board);
+ let bestScore = maximizing ? -Infinity : Infinity;
+
+ for (const move of moves) {
+ const newBoard = this.makeMove(board, move);
+ const score = this.minimax(newBoard, depth - 1, !maximizing);
+
+ if (maximizing) {
+ bestScore = Math.max(bestScore, score);
+ } else {
+ bestScore = Math.min(bestScore, score);
+ }
+ }
+
+ return bestScore;
+ }
+
+ evaluatePosition(board) {
+ let score = 0;
+
+ // Material evaluation
+ score += this.countMaterial(board);
+
+ // Positional bonuses
+ score += this.evaluatePositioning(board);
+
+ // King safety
+ score += this.evaluateKingSafety(board);
+
+ return score;
+ }
+}
+```
+
+**Pros:**
+- Decent playing strength
+- Configurable difficulty via depth
+- Industry-standard algorithm
+- Educational value
+
+**Cons:**
+- Can be slow at higher depths
+- Requires good evaluation function
+- More complex than random
+
+---
+
+#### **Option 3: Alpha-Beta Pruning (Advanced)**
+
+**Difficulty:** Advanced
+**Effort:** 40-60 hours
+**Playing Strength:** Strong (1600-2000+ ELO)
+
+**Enhanced Algorithm:**
+```javascript
+class AlphaBetaAI {
+ alphaBeta(board, depth, alpha, beta, maximizing) {
+ if (depth === 0) {
+ return this.evaluatePosition(board);
+ }
+
+ const moves = this.orderMoves(this.getAllLegalMoves(board));
+
+ for (const move of moves) {
+ const newBoard = this.makeMove(board, move);
+ const score = this.alphaBeta(newBoard, depth - 1, alpha, beta, !maximizing);
+
+ if (maximizing) {
+ alpha = Math.max(alpha, score);
+ if (beta <= alpha) break; // Beta cutoff
+ } else {
+ beta = Math.min(beta, score);
+ if (beta <= alpha) break; // Alpha cutoff
+ }
+ }
+
+ return maximizing ? alpha : beta;
+ }
+
+ orderMoves(moves) {
+ // Move ordering for better pruning
+ return moves.sort((a, b) => {
+ // Captures first
+ // Checks second
+ // Other moves last
+ });
+ }
+}
+```
+
+**Additional Features:**
+- Transposition tables (caching)
+- Iterative deepening
+- Quiescence search
+- Opening book integration
+
+**Pros:**
+- Strong playing ability
+- Much faster than plain minimax
+- Professional-grade implementation
+
+**Cons:**
+- Significant development time
+- Complex debugging
+- Requires optimization expertise
+
+---
+
+#### **Option 4: External Library Integration (Fastest)**
+
+**Difficulty:** Easy-Medium
+**Effort:** 8-12 hours
+**Playing Strength:** Excellent (2500+ ELO possible)
+
+**Recommended Libraries:**
+1. **Stockfish.js** (WASM port of Stockfish)
+ - World-class strength
+ - Well-documented
+ - ~2MB bundle size
+
+2. **chess.js + lozza.js**
+ - Pure JavaScript
+ - Good strength
+ - Smaller bundle (~500KB)
+
+**Implementation Example:**
+```javascript
+import { Chess } from 'chess.js';
+import { Stockfish } from 'stockfish.js';
+
+class StockfishAI {
+ constructor() {
+ this.engine = new Stockfish();
+ this.setupEngine();
+ }
+
+ async getBestMove(fen, difficulty) {
+ return new Promise((resolve) => {
+ this.engine.postMessage(`position fen ${fen}`);
+ this.engine.postMessage(`go depth ${difficulty}`);
+
+ this.engine.onmessage = (event) => {
+ if (event.includes('bestmove')) {
+ const move = this.parseMove(event);
+ resolve(move);
+ }
+ };
+ });
+ }
+}
+```
+
+**Pros:**
+- Fastest implementation
+- Strongest playing ability
+- Well-tested and maintained
+- Multiple difficulty levels
+
+**Cons:**
+- Larger bundle size
+- Less customization
+- External dependency
+- Learning curve for UCI protocol

+### ποΈ Implementation Approaches
+
+#### **Recommended Approach: Incremental Migration**
+
+**Industry Consensus (2024-2025):**
+- β
Incremental migration strongly recommended for codebases over 1,000 lines
+- β
Big-bang migrations get overwhelming and often abandoned
+- β
Productivity drops 10-15% (incremental) vs 30-50% (big-bang)
+
+**Why Incremental:**
+- Game stays functional throughout migration
+- Lower risk of breaking existing features
+- Easier to rollback individual modules
+- Team can learn TypeScript gradually
+- Can deploy partially migrated code
+
+**Timeline Options:**
+
+| Approach | Duration | Hours/Week | Best For |
+|----------|----------|------------|----------|
+| **Aggressive** | 4 weeks | 12-15h | Dedicated focus |
+| **Balanced** β | **6 weeks** | **15-20h** | **RECOMMENDED** |
+| **Conservative** | 8-10 weeks | 5-10h | Learning TypeScript |

+ row: number;
+ col: number;
+}
+
+type Color = 'white' | 'black';
+type Square = number; // 0-63 for board positions
+
+enum PieceType {
+ PAWN = 'pawn',
+ KNIGHT = 'knight',
+ BISHOP = 'bishop',
+ ROOK = 'rook',
+ QUEEN = 'queen',
+ KING = 'king'
+}
+```
+
+#### **Piece Interface**
+```typescript
+interface IPiece {
+ readonly color: Color;
+ readonly type: PieceType;
+ position: Position;
+ hasMoved: boolean;
+
+ getValidMoves(board: IBoard): Position[];
+ canMove(to: Position, board: IBoard): boolean;
+ clone(): IPiece;
+}
+```
+
+#### **Move System**
+```typescript
+enum SpecialMove {
+ NONE,

+const custom = TestBoardFactory.createCustomPosition([...]);
+```
+
+**2. Type-Safe Mocks:**

+
+## π‘οΈ Risk Mitigation Strategies
+
+### Risk 1: Test Failures During Migration
+**Impact:** High | **Probability:** Medium
+
+**Mitigation:**
+- β
One file at a time approach
+- β
Feature branch per file
+- β
Automated rollback via Git
+- β
Keep JS files until complete
+- β
Comprehensive regression tests
+
+### Risk 2: Type Errors Breaking Tests
+**Impact:** Medium | **Probability:** High
+
+**Mitigation:**
+- β
Start with `diagnostics.warnOnly`
+- β
Incremental strict mode adoption
+- β
Type-safe utilities from day 1
+- β
Extensive type testing with `tsd`
+
+### Risk 3: Coverage Drop
+**Impact:** High | **Probability:** Low
+
+**Mitigation:**
+- β
Enforce thresholds in CI (80%+)
+- β
Track per-file coverage
+- β
Visual coverage reports
+- β
Add tests for type-revealed edge cases
+
+## π Key Innovations
+
+### 1. Type-Level Testing
+Using `tsd` to test types themselves:
+```typescript
+expectType('white');
+expectError('red');
+expectAssignable({ type: 'king', ... });
+```
+
+### 2. Test Factory Pattern
+Consistent, type-safe test data creation:
+```typescript
+const board = TestBoardFactory.createStartingPosition();
+const king = TestPieceFactory.createKing('white', pos);
+```
+
+### 3. Incremental Migration
+Never break main branch:
+- One file per PR
+- Full test suite on every commit
+- Automated CI verification
+- Easy rollback if needed
+
+### 4. Multi-Layer Testing
+- Unit: Individual functions (130+ tests)
+- Integration: Component interaction (15+ tests)
+- E2E: User workflows (5+ tests)
+- Type: Type definitions (ongoing)

+## π€ Hive Mind Analysis - Issue #7: Status Message Element Not Found
+
+**Analysis Date:** 2025-11-23
+**Analyzed By:** Hive Mind Collective Intelligence System
+**Status:** β
Root Cause Identified
+
+---
+
+### π― Issue Summary
+
+Console warnings appear when the game tries to display status messages (Check, Checkmate, etc.). The warnings indicate that the status message DOM element is missing from the HTML.
+
+**Console Warnings:**
+```
+[Warning] Status message element not found, using console: β "Check! black king is in check" (main.js, line 245)
+[Warning] Status message element not found, using console: β "Checkmate! white wins!" (main.js, line 245)
+```
+
+---
+
+### π Root Cause Analysis
+
+**File:** `index.html`
+**Location:** Missing element (should be in layout)
+**Problem Type:** Missing DOM Element
+
+**The Bug:**
+```javascript
+// Line 243 in js/main.js
+const statusMessage = document.getElementById('status-message');
+if (!statusMessage) {
+ console.warn('Status message element not found, using console:', message);
+ return;
+}
+```
+
+**Expected Element:** `` or similar
+**Actual State:** **Element does not exist in `index.html`**
+
+**Discrepancy:** The JavaScript code references `'status-message'` but no HTML element has this ID.
+
+---
+
+### β
Verified System Components
+
+**Working Correctly:**
+1. β
**Null safety check** (`js/main.js:244-246`) - Prevents crashes with graceful degradation
+2. β
**showMessage() method** (`js/main.js:242-255`) - Properly implemented with error handling
+3. β
**Message calls** - Check, Checkmate, and other game status messages are triggered correctly
+4. β
**Console fallback** - Messages display in console when element is missing
+
+**The Issue:**
+- β **Missing DOM element** - `id="status-message"` does not exist in `index.html`
+- β **User experience** - Status messages not visible to users (only in console)
+
+---
+
+### π οΈ Fix Implementation
+
+**Solution 1: Add Missing Status Message Element (Recommended)**
+
+Add a status message display area to the HTML layout.
+
+**Location to Add:** After line 23 in `index.html` (inside `.game-status` div)
+
+**HTML to Add:**
+```html
+
+
+
White's Turn
+
Active
+
+
