What streaks and records does the log show?

Every record on this page is scoped to 610 observations spanning 513.3h, and nothing here is called all-time. The log began 2026-09-23 20:04:22 UTC. An all-time high needs a record longer than the claim it carries, and this one is not there yet.

Which streaks are running?

Counted in consecutive observations, not in days — this index observes roughly hourly, and calling three consecutive rises “three days” would be false.

• Attention 7 consecutive rises over 12.7h +5.92
• Capability 2 consecutive rises over 10.6h +1.03
• Composite 2 consecutive rises over 10.6h +1.25
• Compute & Capital 2 consecutive falls over 10.6h −0.04

What is the arithmetic?

• Quietest observation on record: 36.79 of 100 at 2026-09-26 10:20 UTC, out of 610 observations spanning 513.3h.
• Loudest observation on record: 60.67 of 100 at 2026-10-08 03:25 UTC, out of 610 observations spanning 513.3h.
• ROUTINE has held for 513.3h, since 2026-09-23 20:04 UTC.
• Busiest hour in the corpus: 58 items stamped in the hour beginning 2026-10-14 16:00 UTC. Across 16 feeds.
• Highest-scoring item in the window: 93.5 of 100, gnews-ai, 2026-10-14 15:19 UTC.
• 70 of 800 items were carried by more than one independent source; the most-corroborated by 5.

How did every frontier lab fare, last 3 days?

The 800-item cap, not the 7-day window. 324 of 800 items in the corpus name at least one of the 51 entities in the published vocabulary. A lab with no items is a measured zero across the live feeds, not a gap in collection. Market position and mindshare come from Who is winning the AI race?; item counts and release cadence are computed here.

How is this page computed?

An item enters the brief on any one of five rules, not on a blended score. A blend hides which fact did the work; five rules mean every selected item can name the comparison that put it there, and you can redo that comparison against data/news.json with a calculator. Ranking within the brief is the sum of the weights below, then the item’s own news score, then its published time, then its id — a total order, so two runs over one file give one answer.

What is the velocity baseline?

The velocity baseline is live: the corpus holds 42h of history older than the brief window, against the 24h a baseline needs.

What are the engagement thresholds?

Computed per source from this window, not fixed in advance: Hacker News points, Hugging Face upvotes and Hugging Face likes run on three different scales, and a fixed cut-off does not survive a quiet week. A source with fewer than 10 scored items has no threshold and the rule cannot fire for it.

What are the three source states?

live — it answered and it is scored. dark — the fetch or the parse failed; it is excluded and never imputed. awaiting baseline — it answered perfectly and there is no frozen history to score it against yet. Calling the third one dark would claim an outage that is not happening, so this page never merges them, on any surface, in any count.

Every threshold on this page travels inside data/digest.json beside the numbers it produced, so recomputing a selection does not mean matching a file against a commit. The prose version is docs/DIGEST.md.
