# Profile

Profile identity reads and subscribe helpers.

Profile is nested at `client.Auth.Profile`. The API-key-safe surface is subscribe-only:

```go
updates, err := client.Auth.Profile.SubscribeIdentity(ctx)
if err != nil { log.Fatal(err) }
defer updates.Close()

for identity := range updates.Messages() {
	fmt.Println(
		identity.AccountID,
		identity.Username,
		identity.AvatarURL,
		identity.RootSmartAccountAddress,
	)
	break
}
```

The stream does not provide a guaranteed initial profile snapshot. Use `client.Auth.Me(ctx)` for the current API-key identity and the Polyester app to manage profile fields.

`Get`, `Update`, and username-history operations are not included because they require a JWT/session. Configure `DefaultAccountID` explicitly; do not infer it from a stream event during startup.
