Five test modules wrote the same db() over memory_conn, and portable.rs unwrapped it inline; local::test_db() is that. Four pull/push tests wrote the same label INSERT; local::seed_label(conn, id, name, dirty) is it. Both are cfg(test), beside memory_conn, as wire::sample_note is beside wire::Note.
