//! The entry-point name validation is core's ([`alkstore`]'s
//! `validate_shared_name` / `validate_local_name` — ADR-008 §4), same
//! as every engine; this module carries no new rule, only the mem
//! engine's pin that the rule it routes every future entry point
//! through is the family rule: empty and whitespace-only names are
//! `InvalidName`, the reserved prefix `__alkstore_` is `ReservedName`,
//! and the one reserved string (`__alkstore_listener_reconnected__`
//! — the Postgres reconnect channel, unused on this engine) is still
//! rejected because it carries the prefix.
