Five things I found in Google's Agent Registry and Agent Gateway that aren't in the docs

Undocumented features in Google Cloud Agent Registry and Gateway may impact security and integration.

Too early

trajectory — needs a few more snapshots

Why this scored 20

every term, weighted
Velocity+0.6 / 40 max

Engagement gained per hour since the last capture, against the fastest item on its own source

Acceleration+12.5 / 25 max

Whether that velocity is itself speeding up, as a per-hour rate

Cross-source spread+0.0 / 25 max

How many independent communities are talking about the same entity

Recency+7.9 / 10 max

Decays to zero over 14 days

Saturation penalty0.6 / 30 max

Subtracted once something is big and old — we rank what's next, not what's peaked

Composite20.4

Weights are hand-tuned, not learned — we're calibrating them against realized trends as history accumulates. On a topic's first sighting there's no previous reading to compare against, so acceleration starts from a neutral prior rather than a measurement, and velocity falls back to engagement over its whole lifetime until a second reading exists.

Not enough history yet — the trend line fills in as snapshots accrue (every 30 min).
