## Durability contract
What a persistence backend relies on: the durable log persists every event losslessly, **including** `assistant/chunk` — `seq` must stay contiguous, so chunks cannot be filtered out of the canonical log. A backend may choose its own storage encoding for an event batch as long as `load` returns the exact appended events (the JSONL backend's opt-in packed chunk rows are such an encoding — see [persistence.md](persistence.md)). All `event.data` must be JSON-serializable; `Session.append` enforces this at the source (throwing on non-serializable data), so a bad event never enters the log and `session.events` always equals what a backend can persist. Adding an event type that carries non-serializable data, or that breaks the turn/step nesting checked by the session invariant companion, is a breaking change to the on-disk format.

## 持久性契约
持久化后端依赖的契约如下:持久日志无损保存每个事件,**包括** `assistant/chunk``seq` 必须连续,因此不能从规范日志中过滤分片。后端可以为事件批次选择自己的存储编码,只要 `load` 返回与追加时完全一致的事件即可JSONL 后端可选启用的打包分片行就是此类编码;见 [persistence.md](persistence.md))。所有 `event.data` 都必须可序列化为 JSON`Session.append` 会从源头强制这一要求(遇到不可序列化数据时抛出),因此错误事件绝不会进入日志,`session.events` 始终与后端可持久化的内容一致。新增携带不可序列化数据的事件类型,或破坏会话不变式配套插件所检查的轮次/步骤嵌套,会构成磁盘格式的破坏性变更。
