Each of the 32 traits in the **Universal Hex Taxonomy (UHT)** represents a binary property that may or may not apply to an entity. Traits are grouped into four semantic layers: **Physical**, **Functional**, **Abstract**, and **Social**. --- ## [[FF 00 00 00 - Physical Layer]] Describes tangible and material aspects of entities. 1.

[[08 00 00 00 - Structural]] 6. [[04 00 00 00 - Perceptible]] 7. [[02 00 00 00 - Material Form]] 8. [[01 00 00 00 - Passive]] --- ## [[00 FF 00 00 - Functional Layer]] Describes purpose, behavior, and system integration. 9. [[00 80 00 00 - Purposeful or Intentional]] 10. [[00 40 00 00 Emits output or produces effect]] 11. [[00 20 00 00 Processes or regulates logic or signals]] 12. [[00 10 00 00 Transforms or modifies internal state]] 13.
