/**
 * Durable knowledge.db catalog tables. Retained as metadata for `db storage

 *
 * The removed client-side PostgreSQL sync engine connected fleet machines
 * directly to a database URL. Clients now reach the server only through the
 * HTTP ApiStore. This module keeps only on-box,
 * read-only status helpers.
