In everyday language:
- People read, follow, rate, recommend, and finish chapters.
- Those actions refresh story scores like Momentum, Hidden Gem, Bingeable, Critically Acclaimed, Consistency, and Popular — each with its own ingredients and Confidence damping.
- Scheduled snapshot jobs rebuild homepage and Collections shelves from those scores (and apply eligibility gates so low-evidence stories stay off primary rails).
- Explore lanes read the same numbers with filters you choose — they do not invent a second ranking system.
Ratings have their own path into that world — see How Ratings Work. Lexicon words are just friendly names for the same ideas. Public summary page: How Rankings Work.
