“Keep this one. Try a change. You can go back.”
Set up
Compare complete versions without mistaking stale output for current instructions. Use C12's pretend transport pictures, no travel claim. 20 minutes; educator ensures Keep makes a complete authored copy.
Use scrap paper and three broad cards, or a familiar locally approved device. A short chosen part is enough. A wanted helper reads or constructs exactly as directed; name who chooses and who operates.
Run the session
-
Keep current purpose, pictures, meanings and two rules (paper: make or dictate a complete labelled earlier record).
-
Change one child-chosen meaning or link.
-
Apply changes; a previous run/compare must be visibly invalidated.
-
Run the changed route and compare full kept/current versions if wanted.
-
Keep the new version or Restore kept; neither a changed draft nor an old preview is a new run.
-
Record what was changed and one actual outcome or no recorded outcome.
Choose a route
-
118a: Keep, edit, Apply, then compare full digital versions with labelled status.
-
118b: Put earlier/current rule cards side by side and trace the same chosen button through each.
-
118c: Dictate earlier/current keys to a wanted scribe and have both complete sets read aloud/sign/AAC before choosing which to retain. Same version reasoning; no artwork quality ranking.
Notice and next help
If an unchanged screenshot is treated as a new result, deliberately change an unrelated C13 rule and stop before Apply to explain draft/run distinction. Missing record does not prove no operation occurred.
