06 / Clearly labelled interpretation

Editorial reading

Psychological is the highest-priority measured signal in this report. Its latest-month prevalence is 81.8%, compared with 100% in the preceding 90-day window and 100% across the longer baseline. The next useful step is to inspect how the supporting covers execute the feature—not to assume that the feature caused commercial performance.

Interpretation is downstream of measured facts and may not be treated as causation.
