Package kv provides the shared key/value client class used by the valkey and badgerdb plugins.

Package kwarg converts object-side argument errors into Go errors, for typed class constructors whose signatures require an error return.

Package plugintest drives database plugins in external mode: it builds the plugin's cmd binary, loads it through a Manager (handshake, policy, script-shim connect wrappers, object protocol) and evaluates a script against it — the full wire path a real deployment uses.

Package relational provides the shared Connection and Transaction classes used by the database plugins (sqlite, sql).
