//! [`SessionStore`] impl for vti-common's [`KeyspaceHandle`].
//!
//! VTA + VTC use this directly: their `AuthBackend::Store` is
//! `KeyspaceSessionStore` and the trait methods delegate to the
//! free-standing helpers in [`crate::auth::session`].
//!
//! did-hosting writes its own `SessionStore` impl wrapping
//! [`did_hosting_common::server::store::KeyspaceHandle`] —
//! different concrete keyspace type, same trait surface.

/// Thin newtype around [`KeyspaceHandle`] that implements
/// [`SessionStore`].
///
/// Newtype rather than blanket-impl-on-`KeyspaceHandle` so the
/// trait surface stays decoupled from the storage type (orphan
/// rule + future-proofing — a different store would implement
/// `SessionStore` on a different newtype).
