E.11.DSG:5.2 - A non-engineering multilingual suite

A narrative-practice Reference may combine results from independently maintained narrative, language-practice, and pedagogical DPFs for one lesson-planning question. Include all three only if removing any one makes that result insufficient under the stated rule. Otherwise present alternatives or a bounded plausible combination.

A Spanish translation of an English Reference is a derivative episteme when its effective scheme changes. It remains in the same Reference product only while it uses the same reader and use, access rule, warning rule, later-review rule, and retirement rule. A separately established maintenance relation changes product identity only when the identity rule says so. A different Spanish use or current state may select another Reference product even when the title and list of included product series remain recognizable.
