# Project Isolation Bug - Scratchpad

## Task Overview
Fix project isolation bug where ALL sessions appear in every project's left sidebar instead of only that project's sessions.

## Files to Modify
- /home/uroma/obsidian-web-interface/public/claude-ide/project-manager.js (main logic)
- /home/uroma/obsidian-web-interface/public/claude-ide/chat-enhanced.js (left sidebar)

## Root Cause Analysis

After analyzing the code:

1. **project-manager.js line 365**: `switchProject()` calls `loadChatHistory(project.sessions)` - this passes the correct sessions
2. **chat-enhanced.js line 52**: `loadChatHistory()` accepts `sessionsToRender` parameter
3. **BUT** - When `loadChatHistory()` is called without parameters (initial load), it fetches ALL sessions from API

The issue: The left sidebar `loadChatHistory` function is being called in multiple places:
1. Initial page load (no filter) - loads ALL sessions
2. When switching projects (with filter) - should load only project sessions
3. When sessions are created/updated

The problem is that `loadChatHistory` caches and reuses all sessions, and the filtering mechanism isn't working correctly.

## Progress

### Iteration 1 - Analysis - COMPLETED ✅
- Read all relevant files
- Identified the root cause
- Created fix plan

### Next Steps
1. Fix `loadChatHistory` to properly filter by project
2. Ensure sessions are tracked per project correctly
3. Test the fix

## Detailed Root Cause

Looking at `chat-enhanced.js` lines 64-81:
```javascript
if (sessionsToRender) {
  // Use provided sessions (for project filtering)
  allSessions = sessionsToRender;
} else {
  // Fetch all sessions from API
  const res = await fetch('/claude/api/claude/sessions');
  // ... loads ALL sessions
}
```

The problem: When `loadChatHistory()` is called from `switchProject()` with `project.sessions`, it correctly uses those sessions. BUT there are other calls to `loadChatHistory()` throughout the code that don't pass the filter parameter, causing all sessions to load.

Also, the session tabs (`window.sessionTabs.setSessions`) are correctly updated but the left sidebar isn't properly isolated.

## Solution

The fix needs to:
1. Make `loadChatHistory` always respect the current project's sessions
2. Track which project is active globally
3. Filter sessions by the active project's workingDir or project ID
