Critical Errors Found

Error 1: SSE Client Null Reference

File: sse-client.js:41 Error: Cannot set properties of null (setting 'onopen') Fix: Add null check after EventSource construction

Error 2: Array Undefined Access

Files: project-manager.js, chat-enhanced.js, chat-functions.js Error: Cannot read properties of undefined (reading 'length') Fix: Add array validation before operations

Error 3: Race Condition in Session Creation

Pattern: pendingSessionAdd workaround Fix: Replace with optimistic updates + EventBus

Error 4: Virtual WorkingDir Mismatch

Issue: Project "roman" has wrong workingDir in localStorage Fix: Migration script to fix existing projects

Implementation Steps

Step 1: Real-Time Logger (Low Risk)

Create real-time-logger.js with:

• Event logging with context
• Error pattern tracking
• Automatic server reporting
• Visual alert indicators

Step 2: Fix SSE Client (Low Risk)

Modify sse-client.js to:

• Check EventSource before setting handlers
• Handle construction failures gracefully
• Log all connection states

Step 3: Add Array Validation (Low Risk)

Modify affected files to:

• Validate arrays before operations
• Use optional chaining
• Provide fallback empty arrays

Step 4: Project Validator (Medium Risk)

Create project-validator.js to:

• Validate project workingDir consistency
• Migrate existing localStorage projects
• Fix virtual project paths

Step 5: State Manager (High Risk)

Create session-state-manager.js to:

• Centralize all state operations
• Implement transaction-based updates
• Handle optimistic UI updates
• Emit events for all changes

Testing Checklist

Before Deploying

• Real-time logger captures all events
• SSE client handles null EventSource
• Array operations validate inputs
• Project validator fixes existing projects
• State manager passes all transactions

After Deploying

• Create new project "roman"
• Add session to project
• Refresh page - session persists
• Console shows no errors
• Sessions appear in left sidebar

Rollback Plan

If any step fails:

1. Step 1-3: Can be individually reverted without impact
2. Step 4: Migration is one-way, but can be re-run
3. Step 5: Keep old code as fallback, gradual migration

Success Metrics

Must Have (P0)

• ✅ Zero console errors on page load
• ✅ Sessions appear immediately after creation
• ✅ Sessions persist across page refresh

Should Have (P1)

• ✅ Real-time logging active
• ✅ Error alerts working
• ✅ All operations defensive

Nice to Have (P2)

• ✅ Performance monitoring
• ✅ Usage analytics
• ✅ Debug mode toggle
