Add Project Roman session fix analysis and design documentation

This commit includes comprehensive analysis and design documentation for fixing critical session management issues in manually created projects. Phase 1 Complete: - Identified 4 critical errors (SSE null reference, array access, race conditions, virtual workingDir mismatch) - Created detailed root cause analysis - Designed comprehensive solution with 5 components - Complete implementation plan with testing strategy Files added: - ROMAN_SESSION_ISSUE_ANALYSIS.md - Detailed root cause analysis - ROMAN_SESSION_FIX_DESIGN.md - Complete solution design - ROMAN_IMPLEMENTATION_SUMMARY.md - Quick reference guide - PHASE_1_COMPLETE_REPORT.md - Executive summary Next: Awaiting AI Engineer review before implementation Co-Authored-By: Claude <noreply@anthropic.com>

+# Project Roman Session Fix - Phase 2 Design Document
+
+## Executive Summary
+This document outlines the comprehensive fix for the Project Roman session issues. The solution addresses root causes: race conditions, multiple sources of truth, and insufficient error handling.
+
+## Design Principles
+
+### 1. Single Direction Data Flow
+```
+API (Source of Truth)
+        ↓
+  Frontend State (Derived)
+        ↓
+     UI (Computed)
+```
+
+### 2. Optimistic Updates with Rollback
+- Update UI immediately on user action
+- Verify with API in background
+- Rollback on failure
+
+### 3. Event-Driven Architecture
+- All state changes emit events
+- Components subscribe to relevant events
+- No direct state manipulation
+
+## Component 1: Enhanced State Management

+## Implementation Order
+
+### Phase 3: Implementation (Pending AI Engineer Approval)
+
+1. **Step 1: Install Real-Time Logger** (Low Risk)
+   - Add real-time-logger.js to index.html
+   - Test logging functionality
+   - Verify server endpoint exists
+
+2. **Step 2: Fix SSE Client** (Low Risk)
+   - Add null checks to sse-client.js
+   - Test connection with valid session
+   - Test connection with invalid session
+
+3. **Step 3: Add Array Validation** (Low Risk)
+   - Add guards to chat-enhanced.js
+   - Add guards to project-manager.js
+   - Test with empty sessions array
+   - Test with undefined sessions
+
+4. **Step 4: Add Project Validator** (Medium Risk)
+   - Create project-validator.js
+   - Run migration once
+   - Validate existing projects
+
+5. **Step 5: Implement State Manager** (High Risk)
+   - Create session-state-manager.js
+   - Migrate ProjectManager to use it
+   - Test all state transitions
+   - Verify optimistic updates work
+
+## Testing Strategy
+
+### Unit Tests
+- SessionStateManager transactions
+- ProjectValidator migration
+- Array validation functions
+
+### Integration Tests
+- Session creation flow
+- Project switching flow
+- Session persistence flow
+
+### Manual Tests
+1. Create new project
+2. Add session to project
+3. Refresh page
+4. Verify sessions persist
+5. Check console for errors
+
+## Rollback Plan
+
+If any step fails:
+1. Revert specific file changes
+2. Keep existing logger for debugging
+3. Document what failed and why
+4. Adjust approach based on findings
+
+---
+
+**Status:** Phase 2 Complete - Awaiting AI Engineer Review
+**Required Approval:** AI Engineer must review and approve before Phase 3 implementation
+**Review Focus Areas:**
+1. State management architecture
+2. Optimistic update pattern
+3. Error handling strategy
+4. Migration safety
