⚠ Group 1 and Group 2 Excluded
Group 1 and Group 2 30-character messages (the dataset contains over 9,000 such EAMs combined) are excluded from this visualisation by default: at those volumes no individual position-pair clears the 30%-of-messages hot-pair threshold used here, so the heatmap reads as uniform. Structural signals are nonetheless present in both cohorts and are analysed in detail in the 30-character format analysis. This exclusion applies only to Group 1 and 2 messages for this length.
