R.E.T.N.A
Decision Governance Protocol
R.E.T.N.A (Real-time Evaluation and Tracking Neural Assistant) is a decision governance protocol that ensures autonomous systems execute actions only within enforceable policy boundaries.
What the Protocol Does
R.E.T.N.A introduces a deterministic governance boundary between decision proposal and execution.
It evaluates autonomous actions against defined policy constraints, risk modes, and evidence thresholds before privileged execution occurs.
The protocol is designed to ensure that governed systems are not only intelligent, but auditable, policy-bound, and regulator-ready.
Core Governance Functions
Pre-Execution Authorization
Evaluates proposed actions before execution and resolves enforceable outcomes such as allow, deny, escalate, defer, or degrade.
Decision Receipts
Generates auditable governance artifacts that record the policy bundle, evidence references, participants, outcome, and rationale for every governed proposal.
Portable Compliance
Supports enterprise auditability, regulator-grade traceability, and independent validation without requiring a single vendor or model stack.
Reference Implementation
HomeSphere AI serves as the reference implementation of the R.E.T.N.A protocol.
It demonstrates how deterministic physical state, distributed orchestration, and decision governance operate together in a real-world autonomous environment.
Smart-I-Shelf provides the physical ground-truth layer.
HomeSphere AI coordinates structured orchestration.
R.E.T.N.A enforces the final authorization boundary before execution.

Governance Must Precede Execution
R.E.T.N.A introduces the missing governance layer required for autonomous systems to operate safely in real-world environments.
By enforcing deterministic authorization boundaries, auditable decision receipts, and policy-bound execution, the protocol transforms autonomous intelligence into accountable infrastructure.
