 M6 补充：remote history GraphQL/connection 分页现在接受 `hasPrevious`/`hasPreviousPage`、`hasOlder`/`more` 继续分页标记，以及 `previousCursor`/`prevCursor`/`beforeCursor`/`olderCursor` 等 before-id cursor 别名，避免只返回第一页历史。
 
 M6 补充：remote history response parser 现在会递归解包 `data.session.events`、`data.projectSession.eventConnection`、`conversation`、`remoteHistory` 等 GraphQL/session wrapper，继续复用 `nodes`/`edges[].node` 和 `pageInfo` pagination 解析。

 - 本轮补充：嵌套 contract message 接受 `messageId`/`messageID`/`message_id` 和 `messageUuid`/`messageUUID`/`message_uuid` 作为自身 ID/UUID 别名，indexed resume 会保留 payload 自带的 nested message id。
 - 本轮补充：基础 `SessionEntry` JSONL loader 接受 `role`/`entryType`/`messageType`、message ID/UUID、parent ID/UUID 和 `sessionID`/`session`/session UUID 别名，旧 entry 文件可通过 `session.Load` 保留类型、parent 和 session。
+- 本轮补充：tombstone metadata target/parent 加宽到 `targetId`/`deletedId`/`messageId` 和 `parentId`/`parentMessageId` ID/UUID 别名，delete/relink replay 可兼容旧字段拼写。
 - 本轮补充：remote history `SDKEvent` 解码接受顶层 `sessionID` 作为事件 session id 别名，materialize transcript 时会填充 record 与嵌套 message 的 session id（覆盖测试：`TestRemoteHistoryTranscriptMessagesAcceptsSessionIDUpperAlias`）。
 - 本轮补充：remote history `SDKEvent` 解码接受 `parentUUID`、`parentId`/`parentID`/`parent_id`、`parentMessageId`/`parentMessageID`/`parent_message_id` parent aliases，materialize transcript 时会保留 parent chain（覆盖测试：`TestRemoteHistoryTranscriptMessagesAcceptsParentIDAliases`）。
 - 本轮补充：memory 层补齐官方 `memoryAge`/freshness note 语义，`ReadDocumentsWithOptions` 可为超过 1 天的 memory 文档前缀 system-reminder，提示模型把 memory 当作 point-in-time observation 并核对当前代码。

 - `internal/contracts`/`internal/session`: nested contract messages now accept parent aliases such as `parentUUID`, `parentId`/`parentID`/`parent_id`, `parentMessageId`/`parentMessageID`/`parent_message_id`, and parent-message UUID aliases, preserving payload-supplied parents in transcript and remote-history resume paths.
 - `internal/contracts`/`internal/session`: nested contract messages now accept `messageId`/`messageID`/`message_id` and `messageUuid`/`messageUUID`/`message_uuid` as their own ID/UUID aliases, preserving payload-supplied nested message IDs in indexed resume output.
 - `internal/contracts`/`internal/session`: the base `SessionEntry` JSONL loader now accepts role/type, message ID/UUID, parent ID/UUID, and session ID/UUID aliases so older entry files keep type, parent, and session metadata when loaded through `session.Load`.
+- `internal/session`: tombstone metadata target/parent loading now accepts target/deleted/message ID aliases and parent ID/message ID aliases, preserving tombstone delete/relink replay across older field spellings.
 - `internal/session`: remote-history parsing now also accepts connection-style `history`/`messages` wrappers with `nodes`/`edges[].node` event lists and `pageInfo`/`page_info` `hasNextPage`/`endCursor`/`startCursor` pagination aliases.
 - `internal/session`: remote-history connection edges now use `edges[].cursor` as the event cursor when the nested node lacks an event ID, preserving pagination even when pageInfo omits a cursor.
 - `internal/session`: remote-history parsing now also accepts `eventList`/`event_list`, `sessionEvents`/`session_events`, and connection aliases such as `connection`, `eventConnection`, and `sessionEventsConnection`.
