Fixed: WebSocket Reconnection Now Resumes Streaming

Output

✓ Fixed: WebSocket Reconnection

🔍 Root Cause

When your WebSocket reconnected, the server sent turn_start with isReconnect: true, but events that occurred while you were disconnected were lost.

The architecture has two connections:

Browser ↔ Konui (WebSocket) - this reconnects
Konui ↔ Konsole (SSE) - keeps streaming events

Events from the SSE stream were being sent to the original socket object - which was disconnected!

✅ The Fix

Event buffering - Events are now stored per-user during active turns (max 500 events)
Username-based routing - sendEvent() now looks up the currently connected client by username, not the original socket
Replay on reconnect - When you reconnect, all buffered events are replayed to catch you up
Robust delivery - sendError() and endTurn() also use username lookup

🧪 How to Test

Restart konui to apply the fix
Start a turn that runs for a while (e.g., "explore the codebase")
Switch apps or lock your phone briefly
Come back - you should see all events that occurred while away

What's Next?

Restart konui to apply this fix, then test the reconnection behavior.
