+"""Public Python API for Ouroboros.
+
+The package surface only re-exports pure-Python helpers (errors and
+QoS).  Applications import the load-bearing parts of the API from
+their submodule explicitly: flows from :mod:`ouroboros.dev`, the
+event loop from :mod:`ouroboros.event`, and the control plane from
+:mod:`ouroboros.irm` (or :mod:`ouroboros.cli`).  Submodule paths
+make the caller's intent explicit and keep the package importable
+in environments that have no business loading the libouroboros CFFI
+extensions (see ``CLAUDE.md`` for the underlying init-on-load
+behaviour that makes this contract load-bearing in practice).
