# X05 · The background message

**Prepare/source:** Named fictional planet below background mark B at archive date a, above B at date b; B/C relation held in schematic. A separate border moved. **Do:** Child makes a short useful caption and unsent later-record request. **Worked reasoning:** B/C relationship suits this relative-position question; changed border doesn't establish same-frame motion. **Outcome:** A message a future recorder could use. **Next help:** Ask for object/reference/date/status; future answer not fabricated. No planet brightness identification or current hours/direction.
