How can I apply some kind of referential integrity over table B to allow
table B keyed rows to be deleted if table A similar keyed rows are
deleted? Likewise if table A key value changes, table B key values change.

If I remember right, this can be done with a foreign key constraint. See docs for details.

:wq! PoC
