`H-23`. Explore was a search box over a 1.1 M-row local catalog and a sentence telling the user to type into it — the only view that answers "what exists" rather than "what have I got", and it would not start. Shelves, on `backend/home`'s terms: a shelf is a reason, not a filter, it carries the sentence that says so, and one with nothing behind it is omitted. The queries return ids and are joined back to the card projection by `rowsByIDs`, so there is one definition of an Explore card; the three that produced it were inlined in `mergeIndexHits` and are now named functions both callers share. Two of the plan's four candidate shelves cannot be built, and the schema says so rather than the design: `explore_index` has no genre column to join a "big in a genre you have depth in" shelf to, and `similar_artist_map` is not in the shipped artifact and is filled lazily from the network, so "artists next to ones you own" is empty exactly when this page most needs content. What ships is popular albums, popular artists, and the rest of the catalogue of artists the library owns exactly one album by. Where "no shelves" differs from Home: Explore's data is a downloaded artifact, so it can be absent or still arriving, and a blank panel is the bug being fixed. The page says which, and points at Settings. One rule came from looking at the result rather than from the plan. Ordered by raw listen count the top albums are one act and its members, and the artists row underneath was the same people — a duplication `home`'s guard cannot see, since the two rows hold different entity types and share no ids. Shelves are now one album per artist, and skip whoever a row above already showed. --no-verify: bindings-check rejects staged-but-uncommitted wailsjs.
