DACU-BOI v1.2: Sovereign Responsibility Protocol (SRP) — A Deterministic Replay Standard for High-Risk Governance Transparency

This technical reference introduces the Sovereign Responsibility Protocol (SRP), a deterministic replay framework for high-risk governance environments. SRP ensures that responsibility evolution under pre-committed governance parameters cannot be rewritten after outcomes are known. The protocol does not prescribe policy, assign liability, or override sovereign authority. It verifies procedural alignment under immutable input traces and cryptographically locked parameter registries. SRP enables:• deterministic governance replay• accountability injectivity verification• governance vacuum detection• tamper visibility through hash integrity SRP is non-binding, sovereignty-preserving, and policy-neutral. It is offered as a voluntary transparency standard for disaster governance, mountain risk management, evacuation decision review, and high-risk operational environments. This document defines architecture, replay conditions, threat model, and compliance tiers (SRP-Basic through SRP-Sovereign). SRP restores procedural memory without expanding technological authority.
