# Review, Test, Apply, and Rollback AI changes
## Does an AI assistant apply changes automatically?

No. A supported connected assistant prepares a proposal. The proposal does not become live until the customer reviews it and explicitly chooses Apply through Mr.AI.

- Proposal is not production.
- Testing does not publish the proposal.
- Apply requires an explicit customer action.

## Safe proposal lifecycle

1. Open Proposal Review and confirm the affected area, current status, semantic diff, and warnings.
2. Validate the proposal against the current workspace configuration.
3. If the configuration changed or the proposal is stale or conflicting, create and review a fresh proposal instead of forcing the old one.
4. Use Testing when the proposal type supports it. Testing runs separately from production.
5. Choose Apply explicitly only when the proposal is ready and the impact is understood.
6. After Apply, use Rollback only when that change type has a verified rollback snapshot and Mr.AI offers the action.

## How to interpret failures

- Validation failure: the proposal is not ready to apply; inspect the message and refresh the proposal if needed.
- Testing failure: production is not changed by the failed test.
- Apply failure: do not assume the proposal is live; use the returned Mr.AI state as the source of truth.
- Rollback failure: do not assume the previous state was restored until Mr.AI confirms rollback success.

> **Prefer a fresh proposal**
> When in doubt, stop at review and create a fresh proposal from the current configuration instead of trying to rescue a stale proposal.
