Use the visible practice workspace to review a model already approved by a separate expert in FactorySpec. This lesson does not establish production engineering readiness. Check the whole engineering release selection and submit its exact evidence for independent review.

## Prove and submit a FactorySpec release

1. **Load the current FactorySpec source**

   Load the current FactorySpec source

   Read the original source and its saved expected results before continuing.

2. **Open the expert-approved engineering release**

   Open the expert-approved engineering release

   Open the release from FactorySpec’s own list. Expert approval and approval to select this release are separate decisions.

3. **Classify the first release selection**

   Classify the first release selection

   Choose the first-approval classification only because this practice family has no earlier approved selection.

4. **Explain the engineering selection**

   Explain the engineering selection

   Give the reason for selecting this expert-approved model.

5. **Prepare the reviewed release selection**

   Prepare the reviewed release selection

   Ask FactorySpec to compare the approved model with the current family selection.

6. **Verify the complete FactorySpec candidate**

   Verify the complete FactorySpec candidate

   Run the complete native check for this practice selection. The expert-approved model and independently reviewed results remain bound together.

7. **Assemble the exact engineering release selection proposal**

   Assemble the exact engineering release selection proposal

   Keep the complete source, its independent expected results and original proof together.

8. **Request independent FactorySpec release review**

   Request independent FactorySpec release review

   Submit this exact proposal for a separate person to review. This does not activate it.
