  "abstract": "An Empirical Framework for Longitudinal Language-Model Interaction Measurement presents the Semantic Coherence Index (SCI), an empirical framework developed to measure the preservation, transformation, and recurrence of semantic structure across extended language-model interactions. Originating from longitudinal cross-model research and controlled local execution experiments, SCI introduces six measurable dimensions: semantic drift, alignment tax, runtime stability, temporal recurrence, cross-model consistency, and transformation resiliency. The framework distinguishes raw experimental observations from normalized measurements, estimator construction, and downstream interpretation, enabling researchers to evaluate changes in semantic behavior without relying on a single fixed scoring equation or universal threshold. Through controlled comparisons, cross-model transmission, persistent-state analysis, and transformation testing, the manuscript establishes a reproducible methodology for examining semantic continuity and behavioral variation across heterogeneous language-model environments. SCI provides a foundation for investigating model stability, structural preservation, and environmental influences on language-model behavior while supporting independent calibration, validation, and further experimental development.",
