Struct PersistedEvent 

pub struct PersistedEvent {
    pub lsn: i64,
    pub tr_id: Uuid,
    pub doc_id: String,
    pub ts: i64,
    pub actor: Option<String>,
    pub idempotency_key: String,
    pub payload: Vec<u8>,
    pub meta: Value,
    pub checksum: u32,
}

事件存储的“仅追加“记录。

不变式：

• lsn 为后端分配的单调递增日志序号
• idempotency_key 全局唯一，用于请求重试的幂等去重
• checksum 对（压缩/加密后的）payload 计算得到
