```
public final class E2EEEvent

                    
```
A state change reported by StreamEncryptionManager, most usefully a decryption failure for a specific participant. Encryption problems are otherwise silent — media simply arrives undecodable — so this is the main signal for surfacing "you are on a different key" in a UI.

    Parameters:
    
    type - What happened.
    
    name - The event name as reported by the native layer, useful for logs.
    
    userId - The participant the event concerns, when it is scoped to one.
    
    trackType - The track the event concerns, when it is scoped to one.
    
    keyIndex - The key index involved, for key-related events.
    
    version - The frame format version, for E2EEEventType.UNSUPPORTED_VERSION.
    
    reason - Extra detail from the native layer, when present.
    
    keyState - The current key inventory, populated for E2EEEventType.KEY_STATE.
    
    encodePerformance - Per-track encrypt timings, populated for E2EEEventType.PERF_REPORT.
