TSUMS 4.0V: A Replayable Governance Interface for High-Risk Mountain Systems

This technical reference introduces TSUMS 4.0V, a non-binding governance interface designed for high-risk mountain environments. 4.0V provides a deterministic, replayable structure that enables verification of whether operational decisions aligned with pre-committed governance parameters at the time they were made. The framework does not prescribe policy outcomes, assign liability, or override sovereign authority. Instead, it introduces a minimal interface composed of: Immutable input trace Pre-committed parameter registry Deterministic evaluation function Accountability mapping By ensuring that identical inputs and parameters produce identical governance states, 4.0V enhances procedural clarity in environments where post-incident ambiguity often arises. This document is offered as a voluntary transparency reference compatible with existing disaster risk reduction frameworks, including multi-hazard early warning and institutional governance modernization efforts. 4.0V strengthens governance memory without expanding institutional power.
