 ## Overview
 
 When a user triggers a long-running operation (like agent generation), the backend:
+
 1. Spawns a background task that survives SSE disconnections
 2. Returns an `operation_started` response with a `task_id`
 3. Stores stream messages in Redis Streams for replay

 ## Error Handling

 1. Check if task still exists (may have expired - default TTL: 1 hour)
 2. Fall back to polling the session for final state
 3. Show appropriate UI message to user
