X10 · A message another person could adapt
Use C19/C20. Child arranges/directs source label, bounded clue, own purpose, if-plan and open question in any wanted format. A willing reader can suggest one actual change with permission; otherwise the imaginary reader remains clearly imaginary. Check: useful communication and honest unknowns, not polish or public uptake. Next: choose only the missed ordinary relation for another small start.
Complete named ordinary first source
Imaginary paper bulletin labels three parts: a morning-issued forecast of possible evening rain in Book Court; the bulletin-maker's conditional indoor drawing plan if a later relevant record reports rain; an empty evening report slot. An imaginary reader asks “Which part tells us what was actually recorded this evening?” No evening result or actual reader feedback exists.
Other whole ordinary sources. Later notes require grown-up release.
