EcoEchoSystem: A Substrate‑Aligned Simulation Framework for Cognitive, Ecological, and Civilizational Dynamics

EcoEchoSystem is a substrate‑aligned simulation framework designed to model the coupled dynamics of cognition, ecosystems, and civilization under regime‑aware constraints. The framework integrates: cognitive agents with learning, mislearning, and identity dynamics ecological systems with feedback, evolution, and regime transitions civilization‑scale coordination constrained by ecological and cognitive limits a non‑optimizing UI layer for observability, interpretation, and counterfactual exploration a community layer defining research, education, and stewardship practices EcoEchoSystem is not an optimization engine or policy tool. It is a research and learning substrate intended to support disciplined inquiry into complex systems, delayed feedback, irreversibility, and regime change. This record captures the first complete, internally coherent version of the EcoEchoSystem framework as documented in docs/ecoechosystem, establishing a stable reference point for citation, comparison, and long‑arc stewardship.
