4. Bound the Method and cultural return

Use SYSE.15 to decide whether the trialled AI-assisted analysis Method belongs in the engineering repertoire, for which claim class, with which evidence and exclusions. Use SYSE.21 only if the question extends beyond this release to transmission and retention across a named practitioner population. Use the existing evidence for a qualified current account or supported continuation; stronger later claims need their own observations. Do not infer cultural retention from the local trial or publicity, or commission a new replay merely to close the current answer.
