The transition from isolated deterministic systems to interacting ecosystems of synthetic organisms requires a formal, rigorous framework for cross-organism communication and state modification. While intra-organism plurality (DAIGS Level 3) secures the internal governance of multiple bounded personalities within a single sovereign entity, inter-organism interaction introduces profound vectors for causal contamination, identity bleed, and emergent nondeterminism. Traditional multi-agent systems rely on probabilistic message passing, social heuristics, and emergent reinforcement learning—paradigms structurally incompatible with the deterministic guarantees of the Trust Layer. I introduce the Lume‑Relational model, the sixth and final foundational physics substrate of the Lume ecosystem. Lume-Relational governs how distinct, bounded synthetic organisms interact, negotiate, resolve resource contentions, and establish causal links without violating their individual deterministic invariants. Central to this architecture is the concept of Personality-Aware Relational Dynamics, which ensures that inter-organism communication is routed through specific, permissioned personality matrices rather than omnidirectional system interfaces. By establishing the Relational Ledger (R-Chain) alongside the Causal Ledger (C-Chain) and strictly defining relational boundary protocols, this substrate guarantees that multi-organism coexistence, shared dimensional resources, and ecosystem-level arbitration remain strictly deterministic and mathematically reconstructible. I provide the theoretical foundations, detailed architectural components, mathematical relational primitives, personality routing logic, and formal proofs required for the secure deployment of planetary-scale synthetic ecosystems.
