Review the record before drawing a conclusion. Look for missing context, ambiguous labels and claims that exceed the evidence. The purpose is to identify what can be understood from the record and what still requires a separate assessment.

| Overview | The 3-2-1 layout concept |
| Practical example | Read the record without relying on memory; check every label; identify uncertainty; decide whether a specialist review is required; retain the original observation. |
| Limits and interpretation | Thin walls and flexible parts need analysis beyond the rigid-body sketch. |

Measurements and examples are descriptive, not acceptance criteria.
