Description

Mentat uses a single integer, the SQLite user version, to handle base storage schema versioning. At some point it might be useful to abstract this a little, allowing the use of a separate table (à la the "table table" in Firefox for iOS) or other mechanism. This would allow Mentat to cooperatively store data inside an existing SQLite database owned by a conventional consumer.

Contributor guide

Research direction
Investigate the current user version usage in the codebase and propose an abstraction that allows alternative version storage via a table or similar mechanism.
