Struct MutationLogEntry 

pub struct MutationLogEntry {
    pub trace_id: TraceId,
    pub step: usize,
    pub node_id: NodeId,
    pub checkpoint_id: Option<CheckpointId>,
    pub mutation_index: usize,
    pub mutation: Value,
    pub timestamp: SystemTime,
}

Mutation 日志条目 — 持久化审计记录。

使用 serde_json::Value 存储 mutation 内容， 避免在存储层引入对强类型 Mutation 的依赖。

Fields

trace_id: TraceId

执行追踪 ID

step: usize

步骤序号（从 1 开始）

node_id: NodeId

节点标识

checkpoint_id: Option<CheckpointId>

关联的 Checkpoint（如果有）

mutation_index: usize

步骤内的 mutation 序号

mutation: Value

序列化后的 mutation 内容

timestamp: SystemTime

记录时间
