Decimal Narrative Algebra

This paper proposes a modular-ten algebraic structure for narrative operations, seeking to establish an operable interface between formal generation and empirical falsifiability. The system consists of ten narrative atoms and four operators forming a closed set. Through five axioms, nine theorems, and two supplementary layers (perspective and rhythm), it provides a unified mathematical description of plot generation, narrative technique, and stylistic variation. The paper further designs forward-generation and backward-decoding protocols, accompanied by an A/B experimental framework to test empirical validity. The system does not claim exhaustive coverage of narrative phenomena; instead, it explicitly demarcates its own boundaries, offering computational narratology an alternative model subject to verification.
