Why this scored 0

every term, weighted

Velocity+0.0 / 40 max

Its fastest-moving item, measured against the pace of its own source

Acceleration+9.6 / 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 its own items come from

Recency+0.0 / 10 max

Decays to zero over 14 days, counted from when we first saw it

Saturation penalty−11.4 / 30 max

Subtracted once something is big and old — sized by its biggest item, aged from when we first saw it

Composite-1.8 → clamped to 0

Weights are hand-tuned, not learned — we're calibrating them against realized trends as history accumulates. On an entity'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.
