Overview
Queue-based orchestration preserves prioritization. When fifty issues exist, the human or team can decide that only three are critical. An endless agent loop does not naturally represent that decision authority.
Queues also avoid paying for continuous activity when no useful event has occurred. A task runs because something entered the system, not because an agent has been instructed to consume tokens forever.
The model also matches collaborative engineering. Multiple people and agents can participate, tasks can be inspected at each state, and work can be paused or redirected without terminating an opaque process.
