## Definitions

### `app.tempomusic.notification.updateSeen`

**Type**: `procedure`

Mark the requesting viewer's notifications as seen up to seenAt. Server clamps the stored value to max(stored, received) so the marker is monotonic. The viewer DID is read from the service-auth JWT (`iss` claim) — no `?viewer=` query parameter.

#### Input

#### Output
