Can an environment include policy changes while a review is in progress?

**Can MirrorFirm generate more than one policy version?**

A release can include dated policy versions, a change notice and rules describing how the change applies to reviews already under way. The environment can expose each version as a retrievable record rather than embedding the applicable answer in the task prompt.

**What does that enable?**

An insurance servicing review can open under one evidence requirement and reach its decision stage after a revised requirement takes effect. The agent must check whether applicability depends on the opening date, decision date or another stated event.

**Does the newest version always win?**

No. The generated transition rule determines which version governs the review. A later publication date alone should not override an explicit rule for existing cases. Equally, an earlier opening date should not excuse requirements that explicitly apply to all pending decisions.

**What should a buyer request?**

Ask for policy identifiers, publication and effective dates, supersession links and explicit handling of open reviews. Include a policy lookup action and an applicability record in environment state. This lets evaluators inspect whether the agent selected the correct governing rule before assessing its subsequent decision.
