Default Session Bridge

Design a lightweight session helper that boots the package's default messaging instance in an in-memory mode, exposes its primary key-value table, and coordinates a local client connection for reading and writing values.

Capabilities

Start default service

• Starting the session brings up the in-memory messaging service on the default instance using the configured identity and port, and it exposes the default table handle for subsequent operations. @test

Publish and read keys

• After the service starts, publishing a key/value pair stores it in the default table and reading the same key returns the stored value. @test
• Publishing a new value to an existing key overwrites the previous value and the latest value is returned when read. @test

Client observes updates

• Once a local client connection is established, updates to keys in the default table are immediately visible when read through the session. @test

Clean shutdown and restart

• Stopping the session cleanly shuts down the service and releases connections, and starting again yields an empty default table without any previously published keys. @test
