RICIS-III: An Autonomous Lunar Industrial Ecosystem as a Recursive Self-Healing System without a Single Point of Failure

This technical report presents a formal system architecture for a decentralised lunar industrial ecosystem based on the RICIS-III contract layer (Recursive Indexed Calculus of Identity and Singularity). The work extends the RICIS framework from mathematical singularities to structural singularities in multi-agent systems. Every mandatory capability is treated as a structural node whose failure is indexed rather than discarded. The architecture defines seventeen agent classes, a dynamic criticality-based value model, a progressive redundancy hierarchy (R0–R4), a six-stage autonomy roadmap (Seed → Recursive Ecosystem), and an explicit global invariant: no mandatory capability may remain permanently irreplaceable. The contribution is architectural and formal. It provides a machine-readable JSON specification (agents, resources, dependency relations, failure model, redundancy levels, autonomy stages, recursive development algorithm, and terminal conditions) intended for further simulation, verification and implementation. The general idea of self-replicating or closed-loop lunar industry is not claimed as novel; the distinctive element is the consistent application of RICIS contracts and structural criticality indexing to the elimination of single points of failure. This is a preprint technical report. It does not contain experimental validation, quantitative reliability analysis, or a complete physical design of lunar hardware.
