Replay rejects unknown versions, extra fields, reused ids, and delete or dispatch transitions against inactive records. Normal sessions fold the complete log. A fork folds only `session.events.slice(session.header.seedLength ?? 0)`, so it does not inherit its parent's reminders. The package's `./invariant` companion applies the same policy to existing logs and candidate events.

`scheduleReminderPresentation(events, dispatchSeq, seedLength)` is the pure Host-facing receipt projection. It returns `scheduleId`, prompt, occurrence, and `session-local` mode from the dispatch's nearest preceding same-id create. The current fork's `seedLength` is a hard boundary for child-owned dispatches, while inherited dispatches search their persisted prefix; resumed ancestors therefore remain renderable, nested generations may reuse session-local ids, and presentation never changes live ownership. `scheduleReminderPresentation(events, dispatchSeq, seedLength)` is the pure Host-facing receipt projection. It returns `scheduleId`, prompt, and occurrence from the dispatch's nearest preceding same-id create; the client renderer adds the fixed `session-local` label.

`scheduleReminderPresentation(events, dispatchSeq, seedLength)` 是供 Host 使用的纯回执投影。它从 dispatch 之前最近的同 id create 返回 `scheduleId`、prompt、occurrence 和 `session-local` 模式。当前 fork 的 `seedLength` 是 child 自有 dispatch 的硬边界,而继承的 dispatch 则会搜索其已持久前缀;因此恢复后的祖先仍可渲染,嵌套 generation 可以复用会话本地 id,presentation 绝不会改变 live ownership。 `scheduleReminderPresentation(events, dispatchSeq, seedLength)` 是供 Host 使用的纯回执投影。它从 dispatch 之前最近的同 id create 返回 `scheduleId`、prompt 和 occurrence;client renderer 添加固定的 `session-local` 标签。当前 fork 的 `seedLength` 是 child 自有 dispatch 的硬边界,而继承的 dispatch 则会搜索其已持久前缀;因此恢复后的祖先仍可渲染,嵌套 generation 可以复用会话本地 id,presentation 绝不会改变 live ownership。
