The twenty-three title names in §4.6 are the module's defaults. An admin can set their own title per category, once for the site, and it supersedes the default on every server; clearing it restores the default. A rule's own text still wins over both. §4.6 describes the three layers on top of phase 17's rust_title_rules (stat grows from three values to the twenty-three categories).
