 - `frontend/src/features/project-launch/types.ts`、`mockData.ts`、`useProjectLaunchState.ts` 是新项目启动台状态层；默认真实模式通过 `frontend/src/api/pmflowLaunch.ts` 生成草案并确认创建真实项目，API 失败进入明确失败态，不静默 fallback 成 mock 成功；`mockData.ts` 仅在显式 `?demo=1` 或 `?dataSource=demo` 下作为演示状态机使用。`components/LaunchShell.tsx` 负责桌面/移动分流，桌面端复用 `frontend/src/features/personal-space/components/SpaceChrome.tsx` 的空间左侧栏和顶部条，`LaunchCanvases.tsx` 和 `MobileLaunchLayout.tsx` 承接高保真图中的意图输入、AI 工作、人类确认、草案修改、生成失败、创建成功过渡与移动端 bottom sheet 交互。
 - `frontend/src/features/account-settings/AccountSettingsPanel.tsx` 是 `/me` 设置页实现：桌面端为个人资料摘要 + 分区设置面板，移动端为分组列表 + `MobileBottomSheet` 编辑；当前覆盖个人资料、默认语言、AI 回答深度、证据展示偏好、待确认、执行回写、发布门禁和失败提醒通知偏好，并在通知偏好区展示页面内提醒消费说明。`frontend/src/api/accountSettings.ts` 是前端合同层；有 token 时优先调用 `backend/app/api/account_settings_api/`，失败时回落浏览器本机暂存；P2 新增 `shouldShowAccountNotification` 与 `getAccountNotificationConsumption`，将四类通知偏好映射为本地 UI 的待确认、Execution Bridge、Release/Growth 和失败提醒显示/静默状态；P3 新增 `getReleaseGateNotificationPreference(settings, event)`，把 Release/Growth 的 `release_gate_* / release_validation_*` 事件映射到 `releaseGate` 偏好，把 `failed_event` 映射到 `failureAlert` 偏好；P5/P6 的 `getPostReleaseNotificationPreference(settings, event)` 把发布后 `feedback_received / revenue_signal / compliance_blocked` 映射到 `releaseGate` 偏好，把 `iteration_recommendation / next_change_review` 映射到 `pendingConfirmation` 偏好和 `change_review` surface，并返回 `spaceReadable / evidencePolicy / reminderPolicy` 供 Main Flow 与 Space 消费。该合同只控制页面内提醒表达，不代表邮件、桌面推送或系统通知中心已接入；偏好关闭也不得隐藏业务证据、recommendation 或 ChangeSet。`backend/app/schemas/account_settings.py` 定义账号偏好合同，`backend/app/services/account_settings_service.py` 当前复用既有 `integrations` 表按 `tenant_id + user_id` 保存 `account_settings_preferences` 配置包，`backend/app/api/router.py` 已挂载该 API；未改用户表、OAuth/JWT/auth core 或 PMFlow OS truth store。
 - `frontend/src/features/pmflow-os/store.tsx` 当前是 PMFlow OS 共享 truth store：`?projectId=<id>` 时通过 React Query 调用 `frontend/src/api/pmflowOs.ts` 读取真实 `GET /pmflow-os/projects/{project_id}/truth-state` 与 `GET /pmflow-os/projects/{project_id}/execution-summary`，真实模式下项目内 message、`proposed_items` extraction、ChangeItem `accept/edit/defer`、ChangeSet commit、Execution Handoff create/consume、execution progress writeback、release validation run create、release feedback ingest 与 iteration recommendation -> ChangeSet draft 均调用 `/pmflow-os` 后端并 refetch；只有显式 `?demo=1` 或 `?dataSource=demo` 时才启用本地 mock 演示状态机。真实读取/动作失败会进入错误/空态，不静默 fallback 成 mock 成功。
 - `frontend/src/features/pmflow-os/store.tsx` 仍保留演示用项目内 AI 结构化闭环状态机：`command_idle / ai_extracting / extraction_ready / review_open / writeback_success`。`frontend/src/features/pmflow-os/pages/StructuredExtractionPage.tsx` 是本轮结构化提取页，`ChangeReviewPage.tsx` 是决策与待确认中心，`MemoryWritebackResultPage.tsx` 是项目记忆写入结果页，`WorkGraphPage.tsx` 是项目工作台关系总览与对象投影视图，`ExecutionBridgePage.tsx` 是执行桥上下文包、交接按钮、运行端领取确认、PR/测试与回写状态页；`ReleaseGrowthPage.tsx` 真实模式读取 `execution-summary.releaseGate`、`latestValidationRun` 与 `releaseSignals`，从 branch、commit、PR、test、failed evidence 展示 `可发布 / 阻塞 / 需要人工确认 / 缺少证据` 判断、阻塞原因、下一步动作、发布验证记录和发布后 feedback/revenue/recommendation 信号，缺少发布后信号时显示 empty/warning，不执行发布命令、不展示 mock 发布结果；页面可把真实 recommendation 生成下一轮待确认 ChangeSet draft，生成后仍进入 Change Review accept/edit/defer，不自动 commit、不写 Project Memory、不创建正式任务；同时读取 Account notification preference helper，用 `releaseGate` 偏好控制发布门禁强调提醒，用 `failureAlert` 偏好控制失败强调提醒，偏好关闭时只静默提醒表达强度，不隐藏 release evidence、阻塞原因、审计状态、validation run 或 releaseSignals；静态发布/增长原型只保留在显式 demo 模式。A3 已接入后端 truth-state，C1 已接入真实 message/extraction/review 状态机，C2 已接入真实 ChangeSet commit，Phase D 已接入真实 execution-summary/dev-sync，D.2 已接入 `POST /execution-handoffs` 创建 PromptPackage + handoff_created progress event，P1 已接入 `POST /execution-handoffs/{prompt_package_id}/consume` 创建 handoff_consumed progress event 并把 execution status 投影为 coding，Release Growth P1 已接入 execution evidence gate，Release Validation P1 已接入 `POST /release-validation-runs` 创建 `ReleaseValidationRun` 快照，Release Feedback P1 已接入 `POST /release-feedback-ingests` 写入 `FeedbackIngest` 并生成 `IterationRecommendation`，Iteration Loop P1 已接入 `POST /iteration-recommendations/{recommendation_id}/change-set-drafts` 把 recommendation 回流到 Change Review；当前仍不调用真实 AI 提取，不把 mock 当真实失败 fallback。`ProjectMemoryPage.tsx` 在真实模式下展示后端 `truth_nodes + semantic_facts` 的 `projectMemory` 投影，accepted/edited ChangeItem 只有 commit 成功后才进入 Project Memory。`frontend/src/features/pmflow-os/components/ProjectStructuredLoop.tsx` 提供 `StatusLabel / EvidenceSnippet / ObjectChangeCard / ProjectConversationPanel / StructuredExtractionPanel / ProjectAICopilotPanel` 等闭环组件，并复用契约化 `InlineNotice` 表达“未确认不得写入”的局部提示。
