# Interleaved Message Rendering - Complete Implementation

**Date:** 2026-02-16  
**Status:** ✅ Complete (Backend + Frontend)

## Quick Summary

Paprwork V2 now displays agent messages with **interleaved text and tool calls** (like V1):

```
Text response 1
→ Tool call 1 ✓
Text response 2
→ Tool call 2 ✓
Final text
```

Instead of the old V2 format:
```
[All text grouped]
[All tools grouped]
```

## What Changed

### 1. Backend (`SEQUENCE_IMPLEMENTATION.md`)
- Added `sequence` field to `StoredMessage` type
- `streamOrchestrator.ts` tracks text/tool/thinking order during streaming
- SQLite migration adds `sequence` column
- Applies to **all AI models** (Claude, OpenAI, Gemini, etc.)

### 2. Frontend (`SEQUENCE_RENDERING_UI.md`)
- Updated `ChatMessage` type with `sequence` field
- `MessageItem.tsx` renders sequence when available
- Falls back to old rendering for messages without sequence
- Fixed auto-open for `edit_app_file` tool

---

## Testing

Start the app and send a message that uses multiple tools:

```bash
npm start
```

**Example prompt:**
> "List all apps, then read the Reddit app main file, then update it to add a header"

**Expected UI:**
```
┌──────────────────────────────────┐
│ ▼ Exploring                      │
├──────────────────────────────────┤
│ I'll start by listing apps.      │
│ → Apps listed ✓                  │
│                                   │
│ Now reading the main file.       │
│ → File read ✓                    │
│                                   │
│ Updating the file now.           │
│ → File edited ✓                  │
└──────────────────────────────────┘

All done! Your app has been updated.
