Hypergraph-Based Meta-Agents for Mesa

This proposal aims to design and implement a canonical meta-agent architecture for Mesa. The project addresses the current gap between Mesa’s experimental meta-agent support and the needs of users who want to model overlapping group structures such as households, workplaces, alliances, and teams. The work will focus on building a single canonical backend for representing overlapping typed memberships, along with a clean Mesa-facing API for creating groups, updating memberships, handling lifecycle operations, and supporting group-level state aggregation. The expected deliverables are a canonical backend, a user-facing API, lifecycle and aggregation support, tests for correctness and overlapping memberships, and documentation with example-driven validation. The result will be a stronger foundation for multi-level modeling in Mesa and a better base for future group-level extensions.
