Spreadsheet Skeletons Anonymous Operators Love

We ship skeleton tabs with seeded dummy data purely to teach habits. Participants strip noise, annotate anomalies manually, then narrate deltas in prose footers—not sparklines pretending to soothe executives.

The skeleton includes a confession row listing what we refused to summarize because denominators wandered.

Mentor async feedback hits those confession rows hardest; it's where sloppy habits shine first.
