Cathedral-OS / AOAG HAASA v2.0 Technical Handoff Package High-Assurance Governance Architecture for Autonomous Systems

Abstract Cathedral-OS is a prototype governance architecture for autonomous agent operations inhigh-consequence environments. The system combines hardware-timed safety interlocks, software level tri-state consensus, cryptographic auditability, and formal verification scaffolding to reduce unsafe execution pathways and preserve recoverable system state. This handoff package documents the current implementation surface, artifact registry, operational procedures, verification methodology, and bounded-state simulation outputs. Implementedc omponents include a 670 µs hardware safety window via a Deterministic Safety Interlock (Verilog), tri-state decision logic via a Tri-State Quorum Controller (Python), authenticatedstate-transition signing via HMAC-SHA256, and append-only auditability via an Append-OnlyA udit Ledger (SHA-256 Merkle structure). Lean 4 theorem stubs are included to define thei ntended proof surface for bounded state-transition behavior. The lattice structure was created by the other named author and not by myself and I thank her for the contribution.
