# Track Chat Location

```
POST 
/v1/chats/:chat_id/location
```

Record that the current user is viewing `chat_id` at `payload.path`.

The frontend pings this endpoint when a chat becomes active in a panel or when the route changes while a chat is selected. Without it the location table is only populated on user-message send, which orphans chats after /viz/new → /viz/{id} redirects (the user-message that started the chat was sent on /viz/new — no further user message means no /viz/{id} entry).
