Lockbox
Memories that used to mean something slip away.
The nine is how the lab studies what people still claim matters in photos, when the only audience is people they invite.
The question
Photos that used to mean something slip into noise. Feeds reward performance. The lab asks what people still curate when nobody is ranking them.
What the nine is
Nine photos you curate. Invite the people who matter. Not a feed, not an explore page. Cleaning your camera roll keeps the nine honest. You confirm every delete.
How it fits the lab
Cosmos is the algorithm: suppress what is not important, surface what is. Lockbox is the first public product on that stack. The nine is a concrete signal of what someone still claims matters.
One Cosmos account across the lab. What you curate on Lockbox can live in your .polarity file with the rest of your life, so other tools get more personal instead of inventing a new you.
What we are learning
Public and private train different things.
What you put on the nine, what moves in and out, captions, and how invited people respond: that teaches the general Cosmos algorithm how humans claim what matters in photos. Patterns, not your album shared with strangers. Your photos stay yours.
Keep, delete, and private notes: that only improves your own .polarity file, so Cosmos knows you better. Personal suppression, not a shared score.
We are watching whether invite-only honesty holds, whether authored claims beat endless scroll as training ground, and whether people return when the product stays small on purpose.
