Overview

Stores named tags that point to a specific RuleVersion. A tag is a mutable pointer (re-pointing updates the existing row) but the content of the target version is immutable.

version_id is stored as a plain integer without a foreign-key constraint so that tags survive the deletion of the version they originally pointed to.
