 ## 17. Codex 并行开发治理
 
-- 多个 Codex 线程并行推进时，执行单位必须是 `Packet`，不得以模糊“大模块”并行开工。
+- 多个 Codex 线程并行推进时，可以按 `Main Flow / Space / Account Settings / Shell Integration` 等大模块 lane 长期并行，但实际执行单位必须是 `Packet`，不得只以模糊“大模块”直接开工。
-- 每个 Packet 开始前必须有任务包，至少声明 `packet_id / owner_thread / base_ref / read_scope / write_scope / forbidden_paths / shared_files / depends_on / merge_after / verification / docs_to_sync`。
+- 每个 Packet 开始前必须有任务包，至少声明 `packet_id / module_lane / owner_thread / lane_owner / integration_owner / base_ref / read_scope / write_scope / forbidden_paths / shared_files / cross_lane_inputs / cross_lane_outputs / depends_on / merge_after / verification / docs_to_sync`。
 - 没有 `write_scope` 的任务不允许并行；`write_scope` 重叠的 Packet 必须串行。
 - 每轮并行最多一个 `contract / migration / router owner`；其他线程只能消费该 owner 已定义的稳定接口。
+- 大模块并行时，`Shell / Integration owner` 负责共享路由、导航、Provider、共享 API base、共享文档和最终合并；模块线程只能写自己的 owned files。
+- `Space` 线程只做个人空间聚合、草案箱、待确认摘要、AI 进行中摘要和跳转，不直接写 Project Memory、ChangeSet commit 或 Execution Bridge 回写。
+- `Account Settings` 线程只做个人资料、偏好、通知、账户壳和设置入口，不直接改项目主链、权限核心、AI 路由或 Space 聚合。
+- `Main Flow` 线程继续推进 PMFlow OS 主链，但不得顺手重做 Space 或个人中心。
 - 并行线程默认使用独立分支 `codex/<packet_id>`，并优先使用独立 git worktree；不得在同一脏工作区里让多个线程直接写同一批文件。
 - 一个 Packet 对应一个短生命周期分支；Packet 完成、验证通过、文档同步完成后必须形成可审查 commit。复杂 Packet 可在同一分支内做多个逻辑完整 checkpoint commit，但禁止提交半成品、失败验证或越界改动。
 - Codex 完成 Packet 后必须自行执行 commit gate 判定：满足 `auto_commit` 条件时应自行提交；命中 `hold_no_commit` 时不得提交并报告阻塞；命中 `ask_before_commit` 时先说明事实再等用户拍板。具体判定以 `docs/PMFLOW_PRODUCT_DELIVERY_STANDARD.md` 的 `Packet commit 协议` 为准。

+- 本 integration packet 未新增或修改后端运行时代码、Schema 或 migration；本轮未执行热部署/重启。当前验证发生在本地开发工作区，未连接实际部署服务；若要让 Main Flow D.2 的后端提交在部署环境生效，需要在对应部署机执行 `docker compose restart backend`、`scripts/docker_stack.sh restart|dev-restart` 或等价发布流程。
+- Space 的 `savedIdeas` 后端只读聚合合同仍未实现；当前 UI 明确展示 empty/warning，不使用 mock 数据冒充真实内容。
+- Account Settings V1 仍是前端合同 + 本机持久化；跨设备同步需要后续独立新增 `account_settings_api` 与持久化表。
