Why does routing need an interactive environment rather than a fixed answer label?

**Why is a fixed destination label sometimes insufficient?**

A logistics request can clearly belong to dispatch while still requiring a choice between eligible dispatch queues. One queue may stop accepting work after the agent reads its status. The request text has not changed, but the executable decision has.

**What should the environment let the agent do?**

It can expose queue eligibility, current intake status and permitted fallback destinations. The agent can inspect those facts, attempt an assignment and respond to a rejection. A generated event can change availability between inspection and action, making the task depend on fresh state.

**What does that teach?**

It teaches the agent to distinguish a sound category judgement from a valid operational action. Repeating the same assignment after an availability rejection should not be treated as progress. Rechecking eligibility or selecting an authorised fallback can be the useful behaviour.

**Where does MirrorFirm fit?**

A simulated environment could include generated availability events and routing constraints. Builders can use these to test adaptation without defining one permanent queue as the correct answer for every occurrence of a request category.
