# UHT Encoding: Passport ## Summary **Entity**: Passport **Hex Code**: `D7 EF FF FF` **Binary**: `11010111 11101111 11111111 11111111` **Trait Count**: 29 / 32 **Layers Covered**: Physical, Functional, Abstract, Social (all four) --- ## Trait Breakdown ### Physical Layer (1–8) | Bit | Trait | Value | Justification | |-----|----------------------------------|-------|---------------| | 1 | Physical object | 1 | It is a tangible item. | | 2 | Man-made / synthetic | 1 | Manufactured by governments. | | 3 | Biological or biologically-inspired | 0 | Not biological. | | 4 | Fixed/static | 1 | Not dynamic in structure or motion. | | 5 | Structural | 0 | Not a supporting structure. | | 6 | Perceptible | 1 | Visible and touchable. | | 7 | Material form | 1 | Exists as paper/plastic object. | | 8 | Passive | 1 | Does not act on its own. | ### Functional Layer (9–16) | Bit | Trait | Value | Justification | | --- | ------------------------------------- | ----- | ------------------------------------------ | | 9 | Purposeful / intentional | 1 | Created to identify and authorize. | | 10 | Emits output / produces effect | 1 | Grants/denies access at borders. | | 11 | Processes or regulates logic/signals | 1 | Machine-readable with digital data. | | 12 | Transforms or modifies internal state | 0 | Does not change internally. | | 13 | Interacts with humans directly | 1 | Presented to and examined by people. | | 14 | Part of a larger system | 1 | Embedded in legal and immigration systems. | | 15 | Autonomous in function | 0 | Requires a human agent to operate. | | 16 | System-critical | 1 | Essential for international travel. | ### Abstract Layer (17–24) | Bit | Trait | Value | Justification | |-----|----------------------------------|-------|---------------| | 17 | Symbolic / representational | 1 | Symbolizes citizenship. | | 18 | Communicative | 1 | Encodes permissions and identity. | | 19 | Logical / rule-based | 1 | Controlled by legal and policy rules. | | 20 | Hierarchical / modular | 1 | Issued by a nation; recognized globally. | | 21 | Behavior-guiding | 1 | Determines travel permissions and behaviors. | | 22 | Self-referential / meta-conceptual | 0 | Not reflective of itself. | | 23 | Temporal | 1 | Has expiration and issue dates. | | 24 | Contextual abstraction | 1 | Only meaningful in global mobility context. | ### Social Layer (25–32) | Bit | Trait | Value | Justification | |-----|----------------------------------|-------|---------------| | 25 | Socially / culturally constructed | 1 | Based on the concept of nations. | | 26 | Defined by a group/system | 1 | Created and regulated by states. | | 27 | Linked to identity or role | 1 | Core ID document. | | 28 | Regulated / governed | 1 | Strictly controlled by laws. | | 29 | Teachable / transmissible | 1 | People are trained to understand/use it. | | 30 | Visible | 1 | Readily seen and recognized. | | 31 | Context-sensitive | 1 | Activated in borders/travel scenarios. | | 32 | Widely known | 1 | Globally recognized and understood. | --- ## Notes - **Why This Entity?** The passport is a deeply layered socio-technical artifact. It combines bureaucratic logic, symbolic identity, and system-critical function in a passive, portable physical object. - **Code Density Insight:** With 29 active traits, the passport approaches institutional complexity. The absence of traits 3 (biological), 5 (structural), and 22 (self-referential) reflect its non-living, non-reflective nature. - **Nearby Concepts:** - National ID card (slightly fewer traits, less symbolic) - Visa (less durable, more context-dependent) - Digital credential (drops physical layer, boosts trait 11)
