Serial Execution Queue

Details

Each employee now processes one task at a time through a serial execution queue. This prevents conflicts, ensures consistent memory updates, and guarantees that each interaction gets the employee's full attention. Priority handling lets urgent messages jump the queue. Combined with idempotent execution, the system is resilient to retries and duplicate submissions.

What changed

• One-at-a-time execution per employee
• Priority queue for urgent messages
• Idempotent execution safe for retries
• Consistent memory updates without race conditions
