## Definition
The entity is **artificially constructed or engineered**, rather than occurring through natural processes. It is designed, built, or synthesized by human or machine intent.
---
## When to Apply
Use this trait when the entity:
- Is a product of intentional construction or fabrication
- Does not emerge spontaneously in nature
- Is synthetic in origin or composition, even if inspired by natural systems
Avoid applying if the entity is:
- Naturally occurring, even if modified (e.g. a tree, raw mineral)
- Entirely biological and unmodified by intelligent design
- An emergent structure formed without design (e.g. stalactite)
---
## Examples
- A smartphone
- A paperclip
- A concrete building
- A machine learning algorithm
- A plastic water bottle
- A synthetic protein or nanomaterial

## Commentary
This trait captures the **artificial origin** of an entity, which may differ from its behavior or composition. It's important to distinguish *synthetic in origin* from *modified by humans* — a genetically edited plant may still be classified as biological unless its design dominates its identity.
The trait also applies across domains: software code, organizational structures, and cultural artifacts can all be man-made — even if intangible or symbolic in nature.
