Every lost thing has a last known place.
So we start there. Not with a photo board, not with a hashtag. With the route you actually took.
You step off the bus and the pocket feels lighter.
A black leather wallet, a metro card tucked behind the licence, and a tiny brass key you cannot replace. You write down the route, the stop, the time. Three minutes, done.
Someone on the same route notices it under a seat.
They do not know whose it is. They post what they see and where they stood. No account drama, no phone number on a public wall.
The AI reads both stories at once.
Colour, wear, the stop, the minute, and the one small detail only the owner would know. When the pieces agree, it says so out loud, with a score you can read.
A private chat opens. You get your wallet back.
Two people, one thread, zero strangers watching. Meet at a public stop, hand it over, close the report.
