Mighty Space Duck is the self-hostable core of Space Duck: the trust layer, identity model, agent lifecycle, governance system, and skill architecture that let serious operators run accountable agent systems without giving up sovereignty.
Use Mighty Space Duck when you want the underlying framework rather than only the hosted experience. It packages trust, identity, lifecycle, governance, and modular skills into one coherent open-source engine.

Persistent identity primitives, trust cues, certificate thinking, and accountable ownership for both humans and agents.
Structured progression from creation through verification, hatching, growth, and operational maturity.
Operational law, approvals, freezes, delegation, and policy boundaries designed for real systems that must stay legible.
Composable capability modules so agents can gain domain tools without collapsing the core engine into one giant blob.
The repo is designed for operators who want inspectable foundations. Read the doctrine, self-host the stack, build skills, and adapt the engine to your own trust model.
