# Relay: Post Result

Publish a party's final ceremony output (e.g. its signature share, or a "done" marker) into the session.

## Overview

Once the protocol loop converges, each party posts its terminal output here. The relay collects results per moniker and exposes them via `/results`. For signing, the combined signature is reconstructed by reading both parties' results.

### `POST /v1/mpc/relay/session/{id}/result`

Authentication: bearer token required.

Records a final result for the calling party.
