Why am I seeing this Ranked on recency
It is here mostly because it is new. Freshness is the largest single contributor to its score, which means nothing about the story except that it is recent.
Nothing much is corroborating this yet. On a quiet day in ai that is enough to reach the top of the section — recency, not significance, is doing the work here.
Link-outLink-out, because only one organisation carries it and no first-party source is on it. Link-out means we point at the publisher and say nothing of our own.
| Factor | Weight | Score | Contribution | Where it came from |
|---|---|---|---|---|
| Corroboration | 0.35 | 0.39 | +0.135 32% | 1 independent org on the story. Tier-3 aggregators never corroborate — they can show something is circulating, never that it is true. |
| Source trust | 0.25 | 0.44 | +0.110 26% | Tom's Hardware is the highest-trust source on this story. Trust is taken from the best source, not averaged. |
| Pickup rate | 0.20 | 0.00 | +0.000 0% | One counted organisation, so there is no spread to measure — nothing has picked this up to set a rate. |
| Freshnessleads | 0.20 | 0.86 | +0.173 41% | Halves every 10 hours from the newest item on the story. This is the only factor that rewards a story for nothing more than being recent. |
Corroboration counts distinct organisations, once each, and only from tiers 1 and 2 — Hacker News appears on this story and counts for nothing. Freshness halves every 10 hours, so this ranking is a snapshot and will differ at the next build.

What happened
The lawyers of a plaintiff in a labor case attempted to use prompt injection to influence the court's AI but were caught. They won the case anyway, as the defendant did not respond, making the move totally unnecessary.
