Alpha stability and intentional omissions

The v0.1 API is an alpha contract. Pin an exact version and expect incompatible changes between alpha releases.

The project intentionally does not include:

• arbitrary indexing, slicing, concatenation, or positional-axis APIs;

• implicit contractions such as matrix @;

• posterior inference, conditioning, or probabilistic-programming effects;

• mutable RNG sessions or global generator state;

• autodiff, JIT compilation, or graph optimization;

• serialization or a stable custom-node format;

• custom distributions or reductions; or

• alternate numeric backends.

These omissions preserve a small algebra whose stochastic semantics are visible locally in source code. They may be revisited only when a concrete use case can retain that property.
