RFC 0001 — Janus Core Lite v0.1

Status: Draft Author: Martín Nicolás Sánchez Morales Created: 2026

Summary

This RFC defines the minimal governance core for AI-assisted systems.

Janus Core Lite introduces a stack-agnostic governance model based on append-only logs, explicit evidence handling, and traceable human authority.

Motivation

AI-assisted systems increasingly participate in decision processes.

Without explicit governance primitives, systems risk:

• opaque decisions
• untraceable omissions
• shadow sources of truth
• autonomous authority violations

Janus Core Lite provides the minimal ontology required to make governance auditable and reconstructable.

Specification

This RFC formalizes the following components:

• Three canonical append-only logs:
• MANAGEMENT_LOG
• SCHEMA_LOG
• AUDIT_LOG

• Evidence model:
• E+ explicit evidence
• E− omission evidence

• Governance events:
• HUMAN_DECISION
• OMISSION_DETECTED

• Core invariants:
• append-only logs
• separation of domain and governance
• deterministic rebuildability

Normative definitions are specified in:

core/lite/JANUS_CORE_LITE_v0.1.md

Rationale

Core Lite intentionally limits scope to governance primitives.

It does not define runtimes, identity systems, or distributed audit architectures.

Those concerns are addressed in the framework and runtime layers.

Backwards compatibility

Not applicable (initial specification).

Security considerations

Threats addressed in Core Lite include:

• log tampering
• shadow sources of truth
• schema drift
• silent failure
• unauthorized audit writers
• autonomous authority violations
