Title:
The Semantic Holder (SH): Algebraic Extraction for Legal Opposability
Authors: MINKA MI NGUIDJOI Thierry Emmanuel
Abstract:This manuscript introduces Semantic Holder (SH), the opposability primitive within the Chaotic Affine Secure Hash (CASH) toolkit, completing the framework’s implementation of the Q2CSI philosophy. SH enables legally opposable interpretations through algebraic extraction from polynomial iteration traces, working in concert with CEE (confidentiality) and AOW (reliability). Building upon the Affine Iterated Inversion Problem (AIIP) foundation, SH provides mathematically verifiable legal interpretations with guaranteed minimum opposability bounds. We establish that SH maintains an opposability score Ω ≥ 0.60 through rigorous entropy preservation, institutional explainability, and legal contestability guarantees. The primitive features efficient STARK-proof verifiable computation, cross-jurisdictional compatibility, and quantum resistance through its reduction to AIIP hardness. We demonstrate practical applications in legal smart contracts, regulatory compliance auditing, and digital evidence authentication, providing concrete parameter recommendations for standard security levels. SH represents a
significant advancement in cryptographic systems that must operate within legal constraints, enabling transparent and verifiable legal opposability without compromising security or performance.
