Main traits: 1. **A unique identifier**: distinguishes the entity from others, even if the data matches. 2. **State and behavior**: holds data and the rules for changing it. 3. **A lifecycle**: it is created, modified, deleted, and can migrate between systems. Example: `User(id=42, name="Maria")` is still the same entity even if the name changes. **The point:** an Entity models *things that have a history*: people, orders, accounts, documents.For the reviewerNote to the moderator (optional)Visible only to the moderator.
