Not dwelled (scroll-past) — a NEGATIVE ranking signal
Predicted probability the viewer scrolls past without engaging — being ignored is an explicit negative scoring term, not just an absence of positives.
Last public weight: none — this head first appeared publicly in the 2026 release; no weight value has ever been published.
2026 weight: withheld (negative) — all current weights live in an

What actually moves it
A weak first line doesn't merely earn nothing; it actively costs. The hook is a defensive play.
Where it sits in the formula
Phoenix (a Grok-1-architecture transformer, phoenix/README.md)
predicts P(not_dwelled) per viewer from that viewer’s own
engagement history — not from your post’s running like-count. The prediction is
multiplied by its weight and summed with the other 21 terms, then the
author-diversity decay and
out-of-network multiplier apply.
