E.4.CM:4.8.1 - Problem frame

Use this when. You have unlike sources and a recurring practice that needs actionable Method knowledge, but no adequate current description or language already supplies the answer. You need to recover, reconcile, describe and connect the useful contributions while keeping their grounds and limits usable after change.

The intended reader is a practitioner developing Method knowledge or a framework author, able to examine the relevant practice and sources. The first useful result may be one justified allocation, a usable description, or a precise missing basis. A complete language is warranted only when its connected answers repay their construction and maintenance.

Use A.3.2.DE directly when one description is enough. Use E.8.ML when the content is already recovered and allocated and only its language architecture is missing. Use C.39.MC when a finished language or existing result already supplies the present continuation. Those narrower results remain valid exits.
