TSUMS 4.0V (BOI Edition) introduces a non-interventionist governance interface designed for high-risk mountain and disaster environments. This document defines a replayable governance structure that enables institutions to verify whether decisions were made under pre-committed parameters at the time of execution. The framework does not prescribe decisions, assign liability, or override sovereign authority. It provides a deterministic and auditable structure for: • Risk-state traceability • Institutional response latency visibility • Decision replay verification • Accountability mapping under pre-locked governance parameters TSUMS 4.0V operates as a policy-neutral interface layer. Normative judgment and legal authority remain sovereign. This BOI (Boundary of Intervention) edition clarifies that TSUMS functions strictly as a transparency and replay standard, not as a regulatory mechanism. The objective is to reduce post-incident ambiguity in high-risk environments by preserving governance memory through deterministic structural replay. Adoption is voluntary.
