Ansina Just Got a Heart and a Brain​

Deliver three foundational systems that move Ansina from prototype toward a composable, enterprise-ready runtime: a formal Heart protocol, an autonomic tick loop, and a flexible, OpenAI-compatible Brain interface.

Heart: A Formal Runtime Protocol with MLX Support​

The new Heart runtime protocol (heart/runtime.py) formalizes how the agent signals intent and responds to runtime events, making behavior predictable and testable. A dedicated MLX adapter (heart/adapters/mlx.py) bridges the Heart to an external ML execution layer, and new heartbeat endpoints (api/routes/heart.py) give orchestration layers full visibility into runtime state, backed by comprehensive tests.

BrainProvider: Swap Models Without Touching Code​

The new BrainProvider abstraction (brain/provider.py) centralizes model invocation, retries, and selection logic. Paired with an OpenAI-compatible adapter (brain/adapters/openai_compat.py), Ansina now integrates with local models or any third-party provider speaking the OpenAI API standard — no code changes required. Configuration is fully exposed via settings and example files, so teams can switch providers as a configuration decision — a real step toward vendor flexibility and cost control at scale.

Autonomy: A Tick Loop That Keeps Agents Honest​

The new autonomic tick loop (heart/tick/loop.py) drives periodic decision cycles and lifecycle transitions automatically, keeping the agent running gracefully under partial failure. Decision logic, snapshots, and selection strategy are cleanly separated for easier auditing and replay. The loop integrates directly with Heart events and BrainProvider calls, making retries and pacing explicit and observable, with deterministic snapshots supporting reproducible debugging.

Developer Experience and Reliability​

This release also strengthens the foundation for teams building on Ansina: updated docs and architecture blueprints, a fuller dependency lockfile for build reproducibility, a tightened API and error surface for actionable telemetry, and extensive new unit tests across the codebase.

Why This Matters​

Ansina moves decisively toward a production-grade runtime: clear heartbeat contracts, a vendor-agnostic brain interface, and an autonomic loop that keeps agents moving even when components fail. This combination of reliability, interoperability, and configurability makes Ansina worth a closer look.

Onward — building agents with both heart and brain.
