Tech holds -0.40 (7d), the softest reading today, even as an AI ad-tracking cookie story lands on radar's own bluesky layer the same week independent reporting documents the same mechanism, and Google's quantum chip result draws mainstream coverage the same day radar's own science feed carries it.
Both layers agree; the domain's own number does not move to match.
how tech was measured today
Counted layer · the radar, 130 of 208 sources reporting
Tech's day ran 5.6 per 100 sources; usual is 7.8
counted 14:36 UTC · per 100 reporting · against 45 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 45 stamped days before it. The band is the usual range, one standard deviation each side: 29 of 45 days fall in it. All three windows sit below their usual. The numbers -0.71 1 day, in standard deviations
5.6 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-2026-10-17.json counted.domains, scripts/build-cover.py rep_scores.
This is the counted layer: how much the feeds we read published about tech, per source reporting, against what they usually publish. The story above is the heard layer, written from sources. They are kept apart on purpose.
