Why this scored 29
every term, weightedVelocity+10.7 / 40
Its fastest-moving item, measured against the pace of its own source
Acceleration+8.3 / 25
Whether that velocity is itself speeding up, as a per-hour rate
Cross-source spread+0.0 / 25
How many independent communities its own items come from
Recency+9.9 / 10
Decays to zero over 14 days, counted from when we first saw it
Saturation penalty−0.2 / 30
Subtracted once something is big and old — sized by its biggest item, aged from when we first saw it

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.
