# Reference
Reference pages describe Holon's current public surface as it actually behaves —
not as it is planned or promised. They are verified against the compiled
runtime (`holon --help`, `holon config schema`) and should be refreshed when
behavior changes.
> **Stability note:** The runtime is pre-1.0. CLI shapes, config keys, and HTTP
> endpoints may change without prior notice. Each reference page records the
> version it was last regenerated against where applicable. See the repository
> [RFC index](https://github.com/holon-run/holon/tree/main/docs/rfcs) for design direction and stability status.
