# UI Integrity **Domain:** Continuity Engineering / Executable Personhood **UI Integrity** is the capacity of an uploaded or reconstructed person to preserve identity-relevant organization under sustained execution, acceleration, copying, migration, restoration and environmental interaction. It is not equivalent to software uptime. A process may continue running while its memory, values, autobiographical access or relational commitments degrade beyond recognition. _Pantheon_ makes integrity a form of mortality. Heavy computation damages early UIs, so speed becomes metabolic expenditure and repair becomes continuity medicine. The cure then becomes a political resource: whoever controls it can decide which persons continue, which fail and which may be used as repair material. Integrity therefore joins engineering to rights. It requires provenance, checkpoints, semantic re-entry, restoration testing and protection against covert modification. [[wiki/Boot Success Is Not Identity Proof|Boot success]] establishes execution, not identity. A restoration must also answer the [[wiki/State Sufficiency Problem|State Sufficiency Problem]] and preserve [[wiki/Memory Continuity|Memory Continuity]]. ## Runtime Coherence Integrity must be evaluated through time. [[wiki/Runtime Coherence|Runtime Coherence]] asks whether a running person can integrate new experience, revise beliefs and preserve autobiographical order without collapsing into contradiction or fragmentation. Acquisition fidelity and a convincing first boot are necessary evidence, but neither proves longitudinal viability. [[wiki/Fidelity–Plasticity Paradox|The Fidelity–Plasticity Paradox]] adds the complementary warning: exact resemblance can become brittle when the system does not preserve the capacity to forget, reconsolidate, reinterpret and diverge.
