 //! Common backend-neutral Store runtime facade for KSP.
 //!
-//! `0.3.2-pre.002` establishes only the crate and Cargo feature graph. Runtime
-//! settings, backend selection, lifecycle, error mapping and API reexports are
-//! introduced by later prereleases of `0.3.2`.
+//! `0.3.2-pre.003` materializes Config-independent settings, stable backend
+//! identity, bounded validation and the opaque async Store lifecycle contract.
+//! Physical PostgreSQL connection, pool, TLS and migrations remain private
+//! future slices of this release.
 //!
 //! The default `postgres` feature compiles the official PostgreSQL backend as
 //! an optional implementation dependency. No backend implementation type is
 //! part of this crate's public surface.
