Narrative Architecture of Textual Invariance (ANIT): A Structural Model with Computational Verification

ABSTRACT This study proposes the formalization of a structural model entitled Narrative Architecture of Textual Invariance (ANIT), characterized by the complete reorganization of a literary work without any alteration of its textual materiality. The study demonstrates that modifying the structural order of narrative segments may generate a distinct interpretative experience while fully preserving each original textual unit. The central hypothesis maintains that textual invariance is independent of the formal sequence applied, making it possible to alter the structural architecture of a narrative without compromising the material integrity of the text. For empirical verification, two complete versions of the same previously published short story are presented, organized in distinct sequences yet composed of exactly the same textual units. The formal analysis includes descriptive logical modeling, objective criteria of verifiability, and a complete demonstration in the annexes. The results indicate that ANIT constitutes a verifiable structural model in which order functions as an ontological operator capable of producing distinct narrative realities without any rewriting, suppression, insertion, or modification of the textual content. The literary experiment used for demonstration is published in the work Möbius & suiböM (Salgado, 2026), currently available in major international digital book platforms.
