# StatesZoo Router

Open the [states catalog](../../.agents/context/zoos/states-catalog.md) to inspect
existing models. Open [add a state model](../../.agents/context/zoos/add-state-model.md)
only when changing or adding a model.

Keep symbolic parameters and backend representation separate. Verify formulas,
normalization or mixture weights, documented constructor parameters and
introspection, public marking, implemented representations, and targeted
`general/stateszoo` tests.
