HCD.28:11 - SoTA-Echoing
The adopted source distinction from the official 4C/ID overview concerns the contributions named in §4.3. It supports task-centred construction; it does not establish the efficacy of this module or claim coverage of the full Ten Steps book.
HCD.5–8 and HCD.18/.19 supply the developed learning and material methods used here, with their own qualified sources. HCD.20/.22 supply bounded group-design constructions. The whole-product comparison, three-way gap diagnosis and linked diagnostic example are authored combinations of those contributions. Their prospective numerical assumptions require observation; they are not imported effect sizes.
