From Reactive Agents to a Cross-Universe Civilization: Emergent Communication, Institutions, Science, and Invention in a Deterministic Multi-Agent Simulation (v16.0)

This record accompanies the v16.0 release of a deterministic multi-agent simulation in which a small society of artificial agents develops symbolic communication, social institutions, written records, mathematics, proof, law, experimental science, energy technology, automation, and metacognition without any pre-specified lexicon. All word forms emerge from peer interaction under population-level selection pressure. The system is implemented as a chain of backwards-compatible increments (v11 through v16). An automated benchmark of 410 checks passes in full (410/410) in two independent runs that are bit-identical outside wall-clock lines under fixed seeds (main universe: 42; independent contact universe: 777). In the final curriculum stage, the agents invent a device from first principles (a dual-rare-core resonator), conduct a countdown in their own standardized number words, and open a gate whose operation was predicted by their own registered laws. Through this gate, they make first contact with universe B, which evolved independently from seed 777 with no dependence on user code. This release includes the complete source code (simcore package, 28 modules), the simulation entry point (sim_v16.py), run logs from two bit-identical verification runs, a chronicle of events (v16_events.log), a bilingual dialogue transcript (v16_dialogue.log), a cross-universe gate transcript (v16_gate.log), and this report (v16_report_en.pdf). A separate performance-engineering pass reduced wall-clock runtime from approximately 256 seconds to 137 seconds on a two-vCPU environment while preserving the exact trajectory.
