- Method Detail
  - ingestHsiMetrics
```
 final Unit ingestHsiMetrics(Map<String, Object> hsiMetrics)
```
    Ingest pre-computed HRV metrics from the runtime. These are artifact-filtered and authoritative — the session SDK does not compute HRV locally.
  - start

```
    Start a new session.
    
    Parameters:
    
    config - Session configuration.
    
    callback - Called for each event map.
  - stop

 final Unit stop(String sessionId)
```
    Stop a running session.
