Concrete job: “show me more tweets like the ones I just touched.”
You liked or replied to three posts about the same scene (F1, a TV show, a city). SimClusters has already grouped accounts and posts into about 145,000 communities from who engages with whom.
At request time it does not read your bio. It takes those recent engagements and fetches other recent tweets from the same communities. Up to 800.
If you haven’t engaged with anything lately, this door returns nothing. A cold viewer only gets Thunder (follows) and Phoenix retrieval (taste).
It does not score. It only nominates candidates. Phoenix scores them later.
More: Three doors.
