# Keep yesterday's version — if it exists

**Start:** “Keep this one. Shall we try a different link?”
**Do:** Make a complete earlier paper record now, or use an actual retained one; don't invent yesterday's work. Change one rule on a second record, then follow the same button through both. Digital Keep/Apply/Compare can do this locally if available.
**Grown-up:** Current draft, applied version and earlier copy are separate. A helper can scribe both fully. Child may restore or keep either with a reason or private choice. Next re-read the one changed relationship.
