# C16 · A later note can surprise us · educator whole source and model

**Complete FIRST ordinary source:** Invented Amber Room notes: at the stated same March story-hour in years One and Two, clouds were described; at the stated same September story-hour in both years, the sky was described as clear in that view. Another March view is not recorded yet. Save any wanted tentative March idea/reason or record the opportunity declined before releasing the later ordinary note.

**Separate complete LATER ordinary source:** In story year Three's March view, the same imaginary note-maker reports a clear sky from the stated viewpoint. No cause, whole-day weather, whole season or following September result is given.

**Worked meaning:** The first repeated relation remains in the source, and the new exception remains too. Compare with the real saved first contribution; no compulsory mismatch, guess grade or reconstructed prior thought. An unanswered cause question is allowed.
