The self-replication research that sat alone on Hacker News Monday reaches Scientific American and The Atlantic by Thursday, yet tech's own climate reading turns negative for a second straight day, the only domain of the eight still below baseline.
Both layers agree on the story; they disagree on how loud it should read.
how tech was measured today
Counted layer · the radar, 132 of 208 sources reporting
Tech's day ran 9.8 per 100 sources; usual is 7.8
counted 15:46 UTC · per 100 reporting · against 44 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 44 stamped days before it. The band is the usual range, one standard deviation each side: 29 of 44 days fall in it. 1 day and 3 days sit above their usual; 7 days sits below. The numbers +0.67 1 day, in standard deviations
9.8 sources a day per 100, today
7.8 its usual, the mean of 44 days
44 stamped days behind it
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-2026-10-16.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.
