How to read this list

HOW TO READ THIS

A cluster is a group of products whose descriptions sit close together, redrawn from scratch every night. Groups split, merge and disappear between rebuilds, and a group's size can change without a single product changing. Read this as a map of where ideas crowd, not a census — most products sit in no cluster at all.

Many labels here are auto-generated from the group's own text rather than written, and the summaries and gap analyses lag behind the clustering: the pass that writes them has not caught up with the groups the last rebuild created. A missing summary means we have not written one, not that there is nothing to say.

“First seen” is the earliest date any member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so an early date reports how far back a member's own source dated it — not how long we have been watching. The Pulse carries the live totals.
