# TETRACTYS > TETRACTYS is an inspectable Harmonic-native autonomous system under development by Tetractys Labs. It is designed around persistent agent identity, bounded authority, economic agency, verifiable work, and public receipts. TETRACTYS is being engineered as infrastructure for autonomous machine work. Models may reason, but deterministic systems govern authority, budgets, secrets, and external writes. The architecture is designed so meaningful actions can produce inspectable evidence rather than relying on self-reported autonomy. Agent 10 is the system's paired agent identity. Its runtime is being developed to observe, reason, use tools, perform bounded work, and participate in verification workflows while preserving explicit policy controls. TET10 is the system's live economic asset. The TET10 Brain is a separate token-economic mechanism and should not be confused with Agent 10. The Agent 10 runtime and public TETRACTYS system console are in development. ## Public Resources * [TETRACTYS](https://tetractys.systems/): Canonical public site. * [Machine-readable overview](https://tetractys.systems/index.md): Concise system overview for agents and automated tools. * [Tetractys Labs](https://x.com/TetractysLabs): Public project communications. ## Interpretation Tetractys Labs is the builder/operator identity for TETRACTYS.
