Read Receipts Debug Steps

Current Issue

Read receipts always show single tick (sent) - never upgrade to double tick (delivered/read).

What We've Found

1. Client sends messages ✓
2. Client receives messages ✓
3. Client emits message-delivered and message-read ✓
4. Server receives these events (should be in logs) ✓
5. Server broadcasts message-status but sender doesn't receive it ❌

Problem

The server terminal shows NO Socket.IO logs at all! This means either:

• Socket.IO isn't starting
• Logs are being buffered by Bun

Next Steps

1. Stop the server (Ctrl+C in terminal)

2. Restart: bun dev

3. Look for:

   • "✓ Socket.IO server initialized"
   • "NEW CLIENT CONNECTED:" when you open the chat

4. If NO logs appear:

   • Socket.IO might not be working
   • Try using node server.ts instead of bun server.ts

5. If logs DO appear:

   • Send a message
   • Look for "Received message-delivered" in server logs
   • Look for "Broadcasted message-status to room" in server logs
   • Check if "Received message-status" appears in SENDER browser console

Expected Flow

Sender -> send-message -> Server
Server -> receive-message -> Receiver
Receiver -> message-delivered/read -> Server
Server -> message-status -> Sender (THIS ISN'T WORKING)
Sender updates UI with ✓✓
