 - `frontend/src/features/personal-space/` 是空间层入口：`PersonalSpacePage.tsx` 承接桌面个人工作面与独立移动单手布局，`frontend/src/api/space.ts` 只读聚合 `projects` summary、PMFlow OS `truth-state`、`execution-summary` 并生成 `nextActionQueue` 我的下一步队列、继续推进、待确认、review attention、发布关注、发布后反馈关注、下一轮迭代草稿关注、AI 正在推进、草案箱、最近项目摘要；Space P6 的下一步队列按高风险待确认、发布阻塞/失败证据、handoff consumed 后缺少后续 progress、下一轮 draft、发布后反馈/收入/合规信号排序；Space P7 新增 `review_attention`，只读消费 `truth-state.reviewerRouting`，按高风险待我审、`request_changes / rejected` 后待处理、`reviewer_missing` warning、普通 pending review 排序进入“我的下一步”，点击只跳 `/change-review?projectId=<id>&changeSetId=<id>`、已有 `/team-layer?projectId=<id>`、`/execution-bridge?projectId=<id>` 或 `/release-growth?projectId=<id>`；Space P3 的发布关注优先消费 `truth-state.releases` 的 release validation 投影，没有验证投影时才回落 `execution-summary.releaseGate`；Space P4/P5 的发布后反馈/下一轮草稿关注只读消费 `execution-summary.releaseSignals`；不在 Space 写 Project Memory、PMFlowApproval、ProgressEvent、ReleaseValidationRun、FeedbackIngest、RevenueEvent、ComplianceCheckRun、ChangeSet 状态或发布执行，不虚构 reviewer、审查意见或待审 ChangeSet。`components/SpaceChrome.tsx` 承接空间层左侧栏、顶部条与空间用量组件，并被 `/project-launch` 桌面首次新建壳复用；`frontend/src/pages/PersonalSpacePage.tsx` 仅做薄入口。
 - `frontend/src/features/account-settings/` 是 Account Settings 独立产品域：`AccountSettingsPanel.tsx` 承接 `/me` 桌面设置页、移动端分组列表与 bottom sheet，`frontend/src/api/accountSettings.ts` 定义个人资料、默认语言、AI 回答深度、证据展示偏好和四类通知偏好合同；当前已有账号同步 API fallback、本地 UI 通知消费模型、Release/Growth 偏好 helper、post-release / next change review 偏好 helper、`getAccountReminderConsumption(settings, event)` 提醒强度消费合同，以及 `getReviewDecisionNotificationPreference(settings, event)` review decision 偏好合同；支持 `reminderIntensity=silent|normal|prominent` 与 `evidenceDisplay=compact|expanded`，并覆盖 `review_requested / review_approved / review_changes_requested / review_rejected / high_risk_approval_required`；`releaseGate / failureAlert / pendingConfirmation / executionWriteback` 只影响页面内提醒表达强度和证据展开方式，不代表真实邮件、桌面推送或系统通知中心已接入，也不得隐藏真实业务证据、reviewerRouting、approval 或审计状态，不改 OAuth/JWT/auth core；`frontend/src/features/pmflow-os/pages/AccountPage.tsx` 仅做薄入口并复用既有退出登录 bottom sheet。
 - `frontend/src/features/pmflow-os/` 当前承载新的对话驱动前端产品域：`store.tsx` 提供共享 truth store；真实模式通过 `?projectId=<id>` 调用 `frontend/src/api/pmflowOs.ts` 读取后端 `ProjectTruthState` projection，并调用真实 message、`proposed_items` extraction、ChangeItem `accept/edit/defer`、ChangeSet `commit`、review decision、Execution Handoff create/consume、execution progress writeback、release validation run create、release feedback ingest、单条 iteration recommendation -> ChangeSet draft 与同组 iteration recommendation 批量 -> ChangeSet draft API，成功后 refetch truth-state / execution-summary；显式 `?demo=1` 才启用 `command_idle -> ai_extracting -> extraction_ready -> review_open -> writeback_success` 本地演示状态机，以及本地 `promoteAcceptedToGraph` 等演示动作。`pages/` 下包含 `CommandCenter / StructuredExtraction / ChangeReview / MemoryWritebackResult / WorkGraph / ExecutionBridge / ReleaseGrowth / TeamLayer / ProjectMemory / Account` 主页面；`ChangeReviewPage` 真实模式可请求审查、通过、要求修改或拒绝当前 ChangeSet，展示审查状态、建议 reviewer、审查意见和 high-risk approval gate，但不自动 commit；`TeamLayerPage` 真实模式读取 `state.reviewerRouting` 展示 ready/empty/warning、待审 ChangeSet、来源、风险等级、建议审查人或 fallback role、审查原因、待审 item 数、证据数、审查状态、审查意见和请求/决策时间，动作跳转 `/change-review?projectId=<id>&changeSetId=<id>`；`ExecutionBridgePage` 已支持创建 handoff、运行端领取确认和执行进度回写；`ReleaseGrowthPage` 真实模式展示 `execution-summary.releaseGate`、execution evidence、阻塞原因、下一步动作、`latestValidationRun` 和 `releaseSignals`，可创建 release validation run、摄取发布后 feedback、展示 recommendation quality grouping、从真实 recommendation 单条或同组批量生成下一轮待确认 ChangeSet draft，并消费 Account notification preference 静默强调型提醒，但不隐藏真实证据、审计状态或发布后信号；静态发布/增长原型仅保留在显式 demo 模式；后端只记录 review decision/progress/release gate/release validation/release feedback/recommendation draft 元数据，不执行本机命令、真实发布命令、外部支付、真实推送、自动 Project Memory commit 或正式任务创建；`ProjectMemoryPage` 在真实模式消费后端 `truth_nodes + semantic_facts` 的 `projectMemory` 投影，真实模式下 accepted/edited ChangeItem 只有 commit 成功后才进入 Project Memory。`components/` 下除了 `ProjectStageRail / ThreadComposer / ExtractionRail / ChangeGroupPanel / ObjectGraphSection / ContextPacketPanel / ExecutionTimeline / ReleaseGatePanel / TeamFeedPanel` 之外，新增 `ProjectStructuredLoop / PMFlowOsFrame / AccountControls / FeedbackPrimitives` 等行为组件，用来承接项目指挥台、结构化提取、待确认审查、项目记忆写入结果、项目内面包屑、项目切换器、账号退出登录交互，以及 `PageBanner / InlineNotice / HumanDecisionBar / ConfirmDialog / MobileBottomSheet` 这组契约化提示提醒组件；`components/MobileBottomNav.tsx` 是正式应用壳唯一移动底部导航，固定为 `空间 / 指挥台 / 待确认 / 动态 / 我的`。
+- `ProjectTruthState.feed` 现在是 Team Feed 只读动态流，由 `backend/app/services/pmflow_os_projection_service.py` 聚合 review request、review decision、ChangeSet 状态、execution progress 与 release gate 事件；`TeamLayerPage` 复用 `TeamFeedPanel` 展示 `state.feed`，只做摘要、空态和跳转，不写审批、不写 ChangeSet、不写通知，也不在真实模式用 mock 动态补齐。
 - 旧登录实现 `frontend/src/components/ui/sign-in.tsx` 与 `frontend/src/components/ui/demo.tsx` 已移除，`frontend/src/components/login/` 是当前唯一登录真源。

+- `ProjectTruthState.feed` 从静态/局部 feed 扩展为 Team Feed 只读动态流，聚合 review request、review decision、ChangeSet 状态、execution progress 和 release gate 事件。
+- 后端只读消费既有 `PMFlowChangeSet / PMFlowChangeItem / PMFlowApproval / PMFlowEvidenceLink / ProgressEvent / releaseGate` 投影，不新增表、不新增 route、不写审批、不写 ChangeSet、不写通知。
+- `TeamLayerPage` 复用 `TeamFeedPanel` 展示真实 `state.feed`；feed 为空时明确显示无真实动态，不使用 mock 动态冒充团队事件。
+- `TeamFeedPanel` 增加真实时间格式化和空态，保留角色收件箱/决策台为摘要展示，不塞入业务操作。
