                "A user-visible string names no feature of one harness. Public copy and its samples state semantic operations and slots that a binding resolves to whichever harness runs them, so a tool name, a configuration file, a hook event or a product name of one harness in a strings module locks the published practice to that harness. The registry holds the classified names as data; the rule matches each at word boundaries inside every literal and template quasi of a strings module, code samples included, because a sample is where the lock-in lives.",
