Discover collectors and pieces
Discover is the public browse for Autographs 101. You can look for collectors, open pieces they have chosen to show, and jump to guides, the glossary and the signing calendar. If a shelf is empty, nothing public matched. We do not fill the gap with sample people or sample pieces.
A public piece shows the photos and notes its owner published. Prices, estimates and sold records are separate facts. If an owner has not entered an estimate, the page should say that estimates are missing. A zero they typed is a zero. A blank is not a zero.
Collector profiles show the name and the public collection. A visitor does not see private vault notes. Following someone, saving a piece, or starting a trade requires an account, and viewing a profile does not send a message or spend a credit.
Use Discover when you want to see what other collectors are actually showing. Use the guides when you want a how-to. Use Pre-Screen only when you want a photo observation and you have read what it does not do. Those are different jobs.
Guides, the glossary, and the signing calendar are linked from Discover so a browse does not dead-end. A collector name on a public piece stays attached to that collector. Filtered trade pages keep that identity too. Discovery does not rank people by a public score, and it does not show a viewer counter.
