Music's lonely system holds the board's single coldest reading for the second reading in a row, and a dedicated sweep pass again found nothing on the open web to explain it, the kind of sustained signal the routine treats as the day's most valuable precisely because the mainstream hasn't caught up to it.
how music was measured today
Counted layer · the radar, 166 of 236 sources reporting
Music's day ran 4.2 per 100 sources; usual is 5.7
counted 16:05 UTC · per 100 reporting · against 50 stamped days

The signed number is today’s distance from its usual, in standard deviations.
Look for The dot is today; each tick is one of the 50 stamped days before it. The band is the usual range, one standard deviation each side: 33 of 50 days fall in it. All three windows sit below their usual. The numbers -0.62 1 day, in standard deviations
4.2 sources a day per 100, today

Limits It says the volume moved; it does not say why. It counts sources publishing, not a share of all talk. Under 14 stamped days a window reads early, a hollow dot; under 7 it does not print. How it is measured Per 100: sources publishing on the domain in the window, a day, over sources reporting that day, times 100. Usual: the mean of up to 56 stamped days before this sheet, one per scan, this sheet’s own scan left out; the spread is their standard deviation. Deviation: today less the usual, over the spread. src/data/cover-2026-10-22.json counted.domains, scripts/build-cover.py rep_scores.
This is the counted layer: how much the feeds we read published about music, per source reporting, against what they usually publish. The story above is the heard layer, written from sources. They are kept apart on purpose.
